EXECUTIVE SUMMARY

New York University (NYU) is working with the NYC Office of Environmental Remediation

(OER) in the New York City Voluntary Cleanup Program to investigate and remediate an

approximately 80,700-square-foot site located at 181 Mercer Street in New York, New York. A

remedial investigation (RI) was performed to compile and evaluate data and information

necessary to develop this Remedial Action Work Plan (RAWP). The remedial action described

in this document provides for the protection of public health and the environment consistent with

the intended property use, complies with applicable environmental standards, criteria and

guidance and conforms with applicable laws and regulations.

Site Location and Background

The Site is located in the Greenwich Village neighborhood of Manhattan, and occupies the

eastern portion of Block 524, Lot 66 on the NYC Tax Map. The Site occupies a footprint of

about 80,700 square feet. The Site is improved with a one-story building previously occupied by

the NYU Coles Sports Recreation Center, which is located on the city block bound by West

Houston Street to the south, Mercer Street to the east, Bleecker Street to the north and LaGuardia

Place to the west. The building occupies a majority of the Site and includes one cellar and one

sub-cellar level. The recreation center was vacated in January 2016, and interior demolition

work inside the building had begun by the time Langan commenced field work for the RI on

February 23, 2016. The building contains former weight and aerobics rooms, squash and

racquetball courts, dance studios, locker rooms, and two swimming pools. A former dog park,

sitting area and playground occupy the exterior eastern portion of the Site along Mercer Street.

A landscaped area occupies the western exterior portion of the property adjacent to the former

Greene Street Walkway. A Con Edison easement runs along the Greene Street walkway. The

Site elevation at basement grade is about el. 7.5 NAVD 881. The elevation at sidewalk grade

ranges from about el. 34 to el. 36.

1 NAVD88 = North American Vertical Datum of 1988. All elevations presented herein are referenced to

NAVD88, unless otherwise noted.

vii

The redevelopment project is subject to a “Restrictive Declaration of Large -Scale General

Development for the NYU LSGD”, dated July 24, 2012. The Restrictive Declaration (R-218)

covers the phased redevelopment of four contiguous lots (two super blocks) owned by NYU.

The Site occupies the southeastern portion of the redevelopment area and constitutes the first

phase of redevelopment. The Restrictive Declaration applies to hazardous materials, air quality,

and noise concerns. A site location plan is presented in Figure 1. A site boundary map is

provided in Figure 2.

Summary of Redevelopment Plan

The proposed future use of the Site will include demolition of the existing building and paved

exterior areas to construct a new building that will house facilities for NYU students and faculty.

The proposed development will consist of a six-story podium, upon which will be five towers up

to 23-stories high. The building will include two sub-grade levels and will require excavation of

the entire site footprint to about 6.5 feet below the existing sub-grade level (i.e., el. 1.0), which is

about 34 feet below sidewalk grade The cellar and sub-cellar will be extended about 12 feet

west of the current western boundary of the building. Construction of a swimming pool,

stormwater tank, ejector pit, two elevator pits, and mechanical plenum will require deeper

excavation to elevations ranging from about el. -3.0 to -8.5 (i.e., 38 to 42.5 feet below sidewalk

grade) in portions of the site. The new building will contain student and faculty housing,

commercial space, theaters, dining areas, performing arts venues, athletic areas, gymnasiums and

classrooms. The 5,600-square-foot Greene Street Walkway will be repaved, and a landscaping

cover will be placed on the 2,600-square-foot northern exterior area bordering Bleecker Street .

The cellar will house locker rooms, meeting rooms, office space and a performing arts theater.

The sub-cellar will contain four basketball courts, a pool, a wrestling and martial arts studio,

equipment and athletic laundry rooms, storage for athletic equipment and pool supplies,

mechanical rooms and additional locker rooms .

viii

The proposed development plans are provided in Appendix 1. The remedial action contemplated

under this RAWP may be implemented independently of the proposed redevelopment plan.

Summary of Surrounding Property

The Site is located in an urban setting generally characterized by mixed -use residential,

commercial and light manufacturing buildings. The surrounding property usage is summarized

in the following table:

ix

Direction Adjoining Properties Surrounding Properties

North Bleecker Street NYU-owned student and faculty

residential buildings

East Mercer Street Multiple-story mixed-use residential and

commercial buildings

South West Houston Street (underground NYCTA

“F” subway line)

Multiple-story mixed-use residential and

commercial buildings

West Greene Street pedestrian walkway

NYU-owned student and faculty high-rise

residential towers and a Mitchell-Lama

cooperative apartment building

Surrounding properties have been historically occupied by commercial businesses and residential

structures since at least 1894. The Site historically bordered Greene Street on the west, until it

was demapped in the late 1960s. The western adjoining property contained a Con Edison sub -

station in the 1950s and was occupied by the current residential towers by 1969.

Summary of Past Site Uses and Areas of Concern

Historical maps indicate that the Site was located in a densely developed area and improved with

five- and six-story commercial and residential buildings with basements between 1894 and 1950.

Buildings containing a woodwork facility, wool clipping sorting facility, and food products

company were located on the Site in 1950. The buildings were demolished by 1966. Greene

Street was demapped and NYU developed the western adjoining parcel in the late 1960s. The

Site remained a vacant lot until construction of the existing building in approximately 1980. A

March 1981 certificate of occupancy identifies the building as a recreational center.

The following Areas of Concern (AOCs) were identified, based on previous investigations:

1. Potential PCB-Impacted Soil: Soil in the exterior eastern portion of the Site may contain

PCB concentrations above the 6 NYCRR Part 375 Restricted Use Restricted -Residential

(RR) Soil Cleanup Objectives (SCO), based on data from a 2011 sub-surface investigation.

2. Potential Hydraulic Oil Impacts: Potential undetected spills of hydraulic oil from an

elevator may have adversely impacted soil and groundwater.

x

3. Historic Fill Material: The Site was backfilled with historic fill from unknown sources

during its development history. Historic fill may include ash, slag, demolition debris,

municipal waste products and organic and inorganic compounds above the RR SCOs.

4. Historical Site Usage: Potential unreported releases associated with previous uses of the

Site, including vehicle repair and manufacturing facilities, may have adversely impacted

soil, groundwater, and soil vapor.

5. Historical and Current Surrounding Property Usage: Potential unreported releases

associated with a 10,000-gallon fuel oil aboveground storage tank (AST) on an eastern

adjoining property and historical usage of surrounding properties, including a Con Edison

sub-station and vehicle repair, dry cleaning, and manufacturing facilities, may have

adversely impacted soil vapor and groundwater at the Site.

Summary of Work Performed under the Remedial Investigation

The remedial investigation was performed in accordance with the RI Work Plan (RIWP) dated

February 2016 and e-mail approval from NYU for additional sampling in the western exterior

area, dated July 26, 2016. The investigation included:

1. A geophysical survey to identify potential physical obstructions (e.g., vaults, tanks,

utilities, etc.);

2. Advancement of 15 soil borings and collection of 29 grab soil samples, including two

duplicate samples, for chemical analysis to complement existing data and to evaluate soil

quality;

3. Installation of six temporary groundwater monitoring wells and collection of seven

groundwater samples, including one duplicate sample, for chemical analysis to evaluate

groundwater quality; and

4. Installation of six temporary sub-slab soil vapor sample points and collection of seven

soil vapor samples, including one duplicate, and one ambient air sample, for chemical

analysis to evaluate soil vapor quality.

Langan conducted a waste characterization investigation (WCI) concurrently with the RI. The

WCI incorporated the RI borings and included an additional 15 soil borings, from which 66 grab

xi

and 67 composite samples were collected. Composite samples generally included material from

two to three borings. The samples were representative of discrete depth intervals within the

historic fill material and underlying native soil.

Summary of Findings of Remedial Investigation

The findings of the RI are summarized below and presented in an October 2016 Remedial

Investigation Report (RIR):

1. The geophysical survey did not identify anomalies indicative of underground storage

tanks (USTs), abandoned vaults, or other structures of potential environmental concern.

2. Groundwater was encountered at about 6.9 to 7.3 feet below the cellar slab (el. 0.8 to el.

0.5) and at about 33 to 36.7 feet below sidewalk grade (el. 0.3 to el. 0.7) in the eastern

exterior area. Groundwater flow direction is inferred to be from the northeast toward the

southwest.

3. The stratigraphy underlying the Site is comprised of a surficial layer of historic fill

material overlying native sand and silt. Historic fill extends below the cellar floor slab

to depths between about 0.3 and 3 feet below the slab (el. 7.2 to el. 4.5). Historic fill in

the exterior eastern portion of the Site extends to depths from about 30 to 33 feet below

ground surface (bgs) (el. 7 to el. 4). Bedrock was not encountered during the RI;

however, bedrock was encountered between about 55 and 75 bgs (el. -51.5 to el. -18.5)

during a concurrent geotechnical investigation.

4. Historic fill material generally consists of brown fine s and with traces of silt and gravel

interspersed with concrete, glass and brick fragments. Domestic refuse was observed in

shallow fill material in one boring near the northwestern portion of the cellar. Native

soil generally consisting of brown fine and medium sand with varying amounts of silt

underlies the historic fill. Organic vapor concentrations above background, petroleum-

like odors, staining, or other indications of a chemical or petroleum release were not

identified in the soil samples.

5. Soil/fill sample results were compared to NYSDEC Unrestricted Use (UU) Soil Cleanup

Objectives (SCOs) and Restricted Residential (RR) SCOs as presented in 6NYCRR Part

375-6.8 and CP51. Volatile organic compounds (VOCs) and semivolatile organic

xii

compounds (SVOCs) were detected at or below the UU SCOs. Samples of historical fill

material contained the pesticide 4,4’-DDT (max 0.03 mg/kg), and the polychlorinated

biphenyls (PCBs) Aroclor 1254 and Aroclor 1260 (total PCBs 1.11 mg/kg) were

detected at concentrations above the UU SCOs and below the RR SCOs. Four metals,

including lead (max 82.2 mg/kg), mercury (max 0.399 mg/kg), nickel (max 31.9 mg/kg)

and zinc (max 164 mg/kg), were detected at concentrations above the UU SCOs and

below the RR SCOs. Samples of native soil did not contain compounds above the UU

SCOs.

6. Groundwater sample results were compared to 6NYCRR Part 703.5 Class GA

groundwater quality standards (GQS). One groundwater sample (MW21) contained

chloroform (max 8 µg/l) and tetrachloroethylene (PCE) (max 6.3 µg/l) at concentrations

above their respective GQS. Chloroform is a common byproduct of the chlorination

process for drinking water, and PCE is a chlorinated solvent that was historically used in

the commercial dry cleaning process. Four dissolved metals (antimony, manganese,

magnesium, and sodium) were detected in at least one of the six wells at concentrations

above the GQS. The presence of manganese, magnesium, and sodium in each well

indicates that the detections are likely attributable to a regional groundwater condition.

The antimony detection does not correlate with detections in soil samples from the same

boring (EB16) or with detections in other groundwater samples. The occurrence may

therefore reflect a localized condition.

7. Sub-slab soil vapor sample analytical results were evaluated based on the Decision

Matrices presented in the 2006 New York State Department of Health (NYSDOH)

Guidance for Evaluating Soil Vapor Intrusion in the State of New York and the 2013 and

2015 NYSDOH Ambient Air Guideline updates for trichloroethene (TCE) and

tetrachloroethene (PCE). Three of the seven compounds covered by the Decision

Matrices were detected: carbon tetrachloride (max 3 μg/m3), TCE (max 12 μg/m

3), and

PCE (max 6.5 μg/m3). The NYSDOH mitigation recommendations include “no further

action” to “monitor” and “mitigate”, based on the detected soil vapor concentrations.

xiii

Summary of the Remedial Action

The proposed remedial action achieves protection of public health and the environment for the

intended use of the property. The proposed remedial action achieves all of the remedial act ion

objectives established for the project and addresses applicable standards, criterion, and guidance;

is effective in both the short-term and long-term and reduces mobility, toxicity and volume of

contaminants; is cost effective and implementable; and us es standards methods that are well

established in the industry.

The proposed remedial action will consist of:

1. Preparation of a Community Protection Statement and performance of all required

NYC VCP Citizen Participation activities , according to an approved Citizen

Participation Plan.

2. Performance of a Community Air Monitoring Program for particulates and volatile

organic carbon compounds.

3. Selection of NYSDEC Part 375 Unrestricted Use (Track 1) SCOs.

4. Site mobilization involving Site security setup, equipment mobilization, utility mark

outs and marking & staking excavation areas.

5. Completion of a Waste Characterization Study prior to excavation . A Waste

Characterization Study was completed during the RI and additional sampling will be

conducted as required for soil disposal facility approval. Waste characterization soil

samples were collected at a frequency of about one sample per 800 (approximate) cubic

yards of fill to be excavated. A Waste Characterization Report documenting sample

procedures, location and analytical results shall be submitted to OER as part of the

Remedial Action Report (RAR).

6. Excavation and removal of soil and fill exceeding Track 1 Unrestricted Use SCOs

during installation of the temporary support of excavation (SOE) system along the

northern, eastern and western perimeters of the Site. Soldier piles will be drilled to a

depth of about 48 to 50 feet below sidewalk grade (el. -15.0). The eastern and western

exterior portions of the Site will be excavated to the planned sub-grade elevation (el.

1.0), which is about 6.5 feet below the existing sub-grade level and about 34 feet below

sidewalk grade. The below-ground portions of the existing building will be demolished

xiv

during this phase. Approximately 22,000 cubic yards (CY) of soil will be removed

during the SOE phase.

7. Excavation and removal of soil and fill exceeding Track 1 Unrestricted Use SCOs

during bulk excavation in the footprint of the existing building. The footprint of the

former building will be excavated from the existing level (el. 7.5) to the sub -cellar

foundation slab elevation (el. 1.0), which is about 6.5 feet below the existing sub-grade

level and about 34 feet below sidewalk grade. Deeper excavation will occur in the

areas of the proposed swimming pool (el. -3.3 or about 37.5 feet below sidewalk

grade), the elevator pits (el. -4.7 or about 38.5 feet below sidewalk grade) and caissons

and caps (el. -1.5 and -5.0 or about 35.5 and 39 feet below sidewalk grade).

Approximately 16,000 CY of soil will be removed during this phase.

8. Screening of excavated soil and fill during intrusive work for indications of

contamination by visual means, odor, and monitoring with a PID. Appropriate

segregation of excavated media on-Site.

9. Management of excavated materials including temporarily stockpiling and segregating

in accordance with defined material types and to prevent co-mingling of different waste

streams.

10. Removal of underground storage tanks encountered during soil and fill removal

activities. Registration of tanks, reporting of petroleum spills associated with USTs,

and appropriate closure of these petroleum spills in compliance with applicable local,

state and federal laws and regulations.

11. Transportation and off-Site disposal of soil and fill material at licensed or permitted

facilities in accordance with applicable laws and regulations for handling, transport, and

disposal, and this plan. Sampling and analysis of excavated media as required by

disposal facilities. Appropriate segregation of excavated media on -Site.

12. Collection and analysis of end-point samples to determine the performance of the

remedy with respect to attainment of Track 1 SCOs.

13. Import of materials to be used for backfill and cover in compliance with this plan and in

accordance with applicable laws and regulations.

xv

14. Performance of all activities required for the remedial action, including acquisit ion of

required permits and attainment of pretreatment requirements, in compliance with

applicable laws and regulations.

15. Dewatering in compliance with city, state, and federal laws and regulations. Extracted

groundwater will either be containerized for off-site licensed or permitted disposal or

will be treated under a permit from the New York City Department of Environmental

Protection (NYCDEP) to meet pretreatment requirements prior to discharge to the

sewer system.

16. Implementation of storm-water pollution prevention measures in compliance with

applicable laws and regulations.

17. Submission of a Remedial Action Report (RAR) that describes the remedial activities,

certifies that the remedial requirements have been achieved, defines the Site

boundaries, and lists any changes from this RAWP.

If Track 1 Unrestricted Use SCOs are not achieved, the following construction elements

implemented as part of new development will constitute Engineering and Institutional Controls:

As part of development, construction of an engineered site cover system consisting of an

18-inch thick concrete foundation slab beneath all building areas.

As part of development, installation of a waterproofing membrane/vapor barrier system

consisting of vapor barrier beneath the building slab and outside of sub-grade foundation

sidewalls to mitigate soil vapor migration into the building. The system will consist of a

minimum 20-mil thick vapor barrier. The proposed waterproofing membrane/vapor

barrier will be manufactured by Grace Construction Products and will consist of

PrePrufe® 160 and 300R and Bituthene

® 30000/4000, or similar. All welds, seams and

penetrations will be properly sealed to prevent preferential pathways for vapor migration.

COMMUNITY PROTECTION STATEMENT

The NYC Office of Environmental Remediation (OER) provides governmental oversight for the

cleanup of contaminated property in NYC. This Remedial Action Work Plan (“cleanup plan”)

describes the findings of prior environmental studies , shows the location of identified

contamination at the site, and describes the plans to clean up the site to protect public health and

the environment.

This cleanup plan protects neighboring communities and also includes many other elements that

address common community concerns, such as community air monitoring, odor, dust and noise

controls, hours of operation, good housekeeping and cleanliness, truck management and routing,

and opportunities for community participation. The purpose of this Community Protection

Statement is to explain these community protection measures in non -technical language to

simplify community review.

Remedial Investigation and Cleanup Plan: Under the oversight of the NYC OER, a

thorough study of this property (called a remedial investigation) has been performed to identify

past property usage, to sample and test soils, groundwater and soil vapor, and to identify

contaminant sources present on the property. The cleanup plan has been designed to address all

contaminant sources that have been identified during the study of this property.

xvii

Identification of Sensitive Land Uses : Prior to selecting a cleanup, the neighborhood

was evaluated to identify sensitive land uses nearby, such as schools, day care facilities, hospitals

and residential areas. The cleanup program was then tailored to address the special conditions of

this community.

Qualitative Human Health Exposure Assessment: An important part of the cleanup

planning for the Site is a study to find all of the ways that people might come in contact with

contaminants at the Site now or in the future. This study is called a Qualitative Human Health

Exposure Assessment (QHHEA). A QHHEA was performed for this project. This assessment

has considered all known contamination at the Site and evaluated the potential for people to

come in contact with this contamination. All identified potential public exposure pathways will

be addressed under this cleanup plan.

Health and Safety Plan: This cleanup plan includes a Construction Health and Safety Plan

(CHASP) that is designed to protect community residents and on-Site workers. The elements of

this RAWP are in compliance with applicable safety requirements of the United States

Occupational Safety and Health Administration (OSHA). This RAWP includes many protective

elements including those discussed below.

Site Safety Coordinator: This project has a designated Site Safety Coordinator to

implement the CHASP. The safety coordinator maintains an emergency contact sheet and

protocol for management of emergencies. The Site Safety Coordinator is identified at the

beginning of this Community Protection Statement.

Worker Training: Workers participating in cleanup of hazardous material on this project are

required to be trained in a 40-hour hazardous waste operations training course and to take annual

refresher training. This pertains to workers performing specific tasks including removing

contaminated material and installing cleanup systems in contaminated areas.

xviii

Community Air Monitoring Plan: Community air monitoring will be performed during

this cleanup project to ensure that the community is properly protected from contaminants, dust

and odors. Air samples will be tested in accordance with a detailed plan called the Community

Air Monitoring Plan or CAMP. Results will be regularly reported to the NYC Office of

Environmental Remediation. This cleanup plan also has a plan to address any unforeseen

problems that might occur during the cleanup (called a ‘Contingency Plan’).

Odor, Dust and Noise Control: This cleanup plan includes actions for odor and dust

control. These actions are designed to prevent off-Site odor and dust nuisances and includes

steps to be taken if nuisances are detected. Generally, dust is managed by application of physical

covers and by water sprays. Odors are controlled by limiting the area of op en excavations,

physical covers, spray foams and by a series of other actions (called operational measures). The

project is also required to comply with applicable NYC noise control standards. If you observe

problems in these areas, please contact the ons ite Project Manager or NYC Office of

Environmental Remediation Project Manager listed on the first page of this Community

Protection Statement document.

Quality Assurance: This cleanup plan requires that evidence be provided to illustrate that all

cleanup work required under the plan has been completed properly. This evidence will be

summarized in the final report, called the Remedial Action Report. This report will be submitted

to the NYC Office of Environmental Remediation and will be thoroughly reviewed.

Stormwater Management: To limit the potential for soil erosion and discharge, this

cleanup plan has provisions for stormwater management. The main elements of the stormwater

management include physical barriers such as tarp covers and erosion fencing, and a program for

frequent inspection.

Hours of Operation: The hours for operation of cleanup will comply with the NYC

Department of Buildings construction code requirements or according to specific variances

issued by that agency.

xix

Signage : While the cleanup is in progress, a placard will be prominently posted at the main

entrance of the property with a laminated project Fact Sheet that states that the project is in the

NYC Voluntary Cleanup Program and provides project contact names and numbers, and a link to

the document repository where project documents can be viewed.

Complaint Management: The contractor performing this cleanup is required to address all

complaints relating to the cleanup. If you have any complaints, you can call the facility Project

Manager or the NYC Office of Environmental Remediation Project Manager listed on the first

page of this Community Protection Statement document, or call 311 and mention the Site is in

the NYC Voluntary Cleanup Program.

Utility Mark-outs: To promote safety during excavation in this cleanup, the contractor is

required to first identify all utilities and must perform all excavation and construction work in

compliance with NYC Department of Buildings regulations.

Soil and Liquid Disposal: All soil and liquid material removed from the Site as part of the

cleanup will be transported and disposed of in accordance with all applicable City, State and

Federal regulations, and required permits will be obtained.

Soil Chemical Testing and Screening: All excavations will be supervised by a trained

and properly qualified environmental professional. In addition to extensive sampling and

chemical testing of soils on the Site, excavated soil will be screened continuously using hand -

held instruments, by sight, and by smell to ensure proper material handling and management, and

community protection.

Stockpile Management: Soil stockpiles will be kept covered with tarps to prevent dust,

odor and erosion. Stockpiles will be frequently inspected. Damaged t arp covers will be

promptly replaced. Stockpiles will be protected with silt fences. Hay bales will be used, as

needed, to protect storm water catch basins and other discharge points.

xx

Trucks and Covers : Loaded trucks leaving the Site will be covered in compliance with

applicable laws and regulations to prevent dust and odor. Trucks will be properly recorded in

logs and records and placarded in compliance with applicable City, State and Federal laws,

including those of the New York State Department of Transportation. If loads contain wet

material that can leak, truck liners will be used. All transport of materials will be performed by

licensed truckers and in compliance with applicable laws and regulations.

Imported Material: All fill materials proposed to be brought onto the Site will comply with

rules outlined in this cleanup plan and will be inspected and approved by a qualified worker

located on the Site. Waste materials will not be brought onto the Site. Trucks entering the Site

with imported clean materials will be covered in compliance with applicable laws and

regulations.

Equipment Decontamination: All equipment used for cleanup work will be inspected and

washed, if needed, before it leaves the Site. Trucks will be cleaned at a truck inspection station

on the property before leaving the Site.

Housekeeping: Locations where trucks enter or leave the Site will be inspected every day

and cleaned regularly to ensure that they are free of dirt and other materials from the Site.

Truck Routing: Truck routes have been selected to: (a) limit transport through residential

areas and past sensitive nearby properties; (b) maximize use of city -mapped truck routes; (c)

limit total distance to major highways; (d) promote safety in entry to highways; (e) promote

overall safety in trucking; and (f) minimize off-Site line-ups (queuing) of trucks entering the

property. Operators of loaded trucks leaving the Site will be instructed not to stop or idle in the

local neighborhood.

Final Report: The results of all cleanup work will be fully documented in a final report

(called the Remedial Action Report) that will be available for public review online. A link to the

xxi

online document repository and the public library with Internet access nearest the Site are listed

on the first page of this Community Protection Statement document

Long-Term Site Management: If long-term protection is needed after the cleanup is

complete, the property owner will be required to comply with an ongoing Site Management Plan

that calls for continued inspection of protective controls, such as Site covers. The Site

Management Plan is evaluated and approved by the NYC Office of Environmental Remediation.

Requirements that the property owner must comply with are defined either in the property’s deed

or established through a city environmental designation registered with the Department of

Buildings. A certification of continued protectiveness of the cleanup will be required from time

to time to show that the approved cleanup is still effective.

REMEDIAL ACTION WORK PLAN

1.0 Project Background

New York University (NYU) is working with the NYC Office of Environmental Remediation

(OER) in the New York City Voluntary Cleanup Program and in the Restrictive Declaration

Program to investigate and remediate a property located at 181 Mercer Street in the Greenwich

Village section of New York, New York (the “Site”). A Remedial Investigation (RI) was

performed to compile and evaluate data and information necessary to develop this Remedial

Action Work Plan (RAWP) in a manner that will render the Site protective of public health and

the environment consistent with the contemplated end use. This RAWP establishes remedial

action objectives, provides a remedial alternatives analysis that includes consideration of a

permanent cleanup, and provides a description of the selected remedial action. The remedial

action described in this document provides for the protection of public health and the

environment, and complies with applicable environmental standards, criteria and guidance and

applicable laws and regulations.

1.1 Site Location and Background

The Site is located in the Greenwich Village neighborhood of Manhattan, and occupies the

eastern portion of Block 524, Lot 66 on the NYC Tax Map. The Site occupies a footprint of

about 80,700 square feet. The Site is improved with a one-story building previously occupied by

the NYU Coles Sports Recreation Center, which is located on the city block bound by West

Houston Street to the south, Mercer Street to the east, Bleecker Street to the north and LaGuardia

Place to the west. The building occupies a majority of the Site and includes one cellar and one

sub-cellar level. The recreation center was vacated in January 2016, and interior demolition

work inside the building had begun by the time Langan commenced field work for the RI on

February 23, 2016. The building contains former weight and aerobics rooms, squash and

racquetball courts, dance studios, locker rooms, and two swimming pools. A former dog park,

sitting area and playground occupy the exterior eastern portion of the Site a long Mercer Street.

A landscaped area occupies the western exterior portion of the property adjacent to the former

Greene Street Walkway. A Con Edison easement runs along the Greene Street walkway. The

2

Site elevation at basement grade is about el. 7.5 NAVD 882. The elevation at sidewalk grade

ranges from about el. 34 to el. 36.

The redevelopment project is subject to a “Restrictive Declaration of Large -Scale General

Development for the NYU LSGD”, dated July 24, 2012. The Restrictive Declaration (R-218)

covers the phased redevelopment of four contiguous lots (two super blocks) owned by NYU.

The Site occupies the southeastern portion of the redevelopment area and constitutes the first

phase of redevelopment. The Restrictive Declaration applies to hazardous materials, air quality,

and noise concerns. A site location plan is presented in Figure 1. A site boundary map is

provided in Figure 2.

1.2 Redevelopment Plan

The proposed future use of the Site will include demolition of the existing building and paved

exterior areas to construct a new building that will house facilities for NYU students and faculty.

The proposed development will consist of a six-story podium, upon which will be five towers up

to 23-stories high. The building will include two sub-grade levels and will require excavation of

the entire site footprint to about 6.5 feet below the existing sub-grade level (i.e., el. 1.0), which is

about 34 feet below sidewalk grade The cellar and sub-cellar will be extended about 12 feet

west of the current western boundary of the building. Construction of a swimming pool,

stormwater tank, ejector pit, two elevator pits, and mechanical plenum will require deeper

excavation to elevations ranging from about el. -3.0 to -8.5 (i.e., 38 to 42.5 feet below sidewalk

grade) in portions of the site. The new building will contain student and faculty housing,

commercial space, theaters, dining areas, performing arts venues, athletic areas, gymnasiums and

classrooms. The cellar will house locker rooms, meeting rooms, office space and a performing

arts theater. The sub-cellar will contain four basketball courts, a pool, a wrestling and martial

arts studio, equipment and athletic laundry rooms, storage for athletic equipment and pool

supplies, mechanical rooms and additional locker rooms . The 5,600-square-foot Greene Street

Walkway will be repaved, and a landscaping cover will be placed on the 2,600-square-foot

in Appendix 1.

1.3 Description of Surrounding Property

The Site is located in an urban setting generally characterized by mixed -use residential,

commercial and light manufacturing buildings. The surrounding property usage is summarized

in the following table:

Direction Adjoining Properties Surrounding Properties

North Bleecker Street NYU-owned student and faculty

residential buildings

East Mercer Street Multiple-story mixed-use residential and

commercial buildings

South West Houston Street (underground NYCTA

“F” subway line)

Multiple-story mixed-use residential and

commercial buildings

West Greene Street pedestrian walkway

NYU-owned student and faculty high-rise

Surrounding properties have been historically occupied by commercial businesses and residential

structures since at least 1894. The Site historically bordered Greene Street on the west, until it

was demapped in the late 1960s. The western adjoining property contained a Con Edison sub-

station in the 1950s and was occupied by the current residential towers by 1969.

1.4 Summary of Past Site Uses and Areas of Concern

Historical maps indicate that the Site was located in a densely developed area and improved with

five- and six-story commercial and residential buildings with basements between 1894 and 1950.

Buildings containing a woodwork facility, wool clipping sorting facility, and food products

company were located on the Site in 1950. The buildings were demolished by 1966. Greene

Street was demapped and NYU developed the western adjoining parcel in the late 1960s. The

Site remained a vacant lot until construction of the existing building in approximately 1980. A

March 1981 certificate of occupancy identifies the building as a recreational center.

The following Areas of Concern (AOCs) were identified, based on previous investigations:

1. Potential PCB-Impacted Soil: Soil in the exterior eastern portion of the Site may contain

PCB concentrations above the 6 NYCRR Part 375 Restricted Use Restricted -Residential

(RR) Soil Cleanup Objectives (SCO), based on data from a 2011 sub-surface investigation.

2. Potential Hydraulic Oil Impacts: Potential undetected spills of hydraulic oil from an

elevator may have adversely impacted soil and groundwater.

3. Historic Fill Material: The Site was backfilled with historic fill from unknown sources

during its development history. Historic fill may include ash, slag, demolition debris,

municipal waste products and organic and inorganic compounds above the RR SCOs.

5

4. Historical Site Usage: Potential unreported releases associated with previous uses of the

Site, including vehicle repair and manufacturing facilities, may have adversely impacted

soil, groundwater, and soil vapor.

5. Historical and Current Surrounding Property Usage: Potential unreported releases

associated with a 10,000-gallon fuel oil aboveground storage tank (AST) on an eastern

adjoining property and historical usage of surrounding properties, including a Con Edison

sub-station and vehicle repair, dry cleaning, and manufacturing facilities, may have

adversely impacted soil vapor and groundwater at the Site.

1.5 Summary of Work Performed under the Remedial Investigation

To investigate AOCs identified during previous investigations and evaluate soil, groundwater,

and soil vapor quality, Langan performed the following scope of work during a Remedial

Investigation (RI) conducted in February, March, and July 2016:

1. A geophysical survey to identify potential physical obstructions (e.g., vaults, tanks,

utilities, etc.);

2. Advancement of 15 soil borings and collection of 29 grab soil samples, including two

duplicate samples, for chemical analysis to complement existing data and to evaluate soil

quality;

3. Installation of six temporary groundwater monitoring wells and collection of seven

groundwater samples, including one duplicate sample, for chemical analysis to evaluate

groundwater quality; and

4. Installation of six temporary sub-slab soil vapor sample points and collection of seven soil

vapor samples, including one duplicate, and one ambient air sample, for chemical analysis

to evaluate soil vapor quality.

Langan conducted a waste characterization investigation (WCI) concurrently with the RI. The

WCI incorporated the RI borings and included an additional 15 soil borings, from which 66 grab

and 67 composite samples were collected. Composite samples generally included material from

two to three borings. The samples were representative of discrete depth intervals within the

historic fill material and underlying native soil.

6

1.6 Summary of Findings of Remedial Investigation

A remedial investigation was performed and the results are documented in a companion

document called “Remedial Investigation Report, 181 Mercer Street”, dated October 2016 (RIR).

A copy of the RIR, which includes copies of previous environmental reports, is provided in

Appendix 2. The findings of the RI are summarized below:

1. The geophysical survey did not identify anomalies indicative of underground storage tanks

(USTs), abandoned vaults, or other structures of potential environmental concern.

2. Groundwater was encountered at about 6.9 to 7.3 feet below the cellar slab (el. 0.8 to el.

0.5) and at about 33 to 36.7 feet below sidewalk grade (el. 0.3 to el. 0.7) in the eastern

exterior area. Groundwater flow direction is inferred to be from the northeast toward the

southwest.

3. The stratigraphy underlying the Site is comprised of a surficial layer of historic fill material

overlying native sand and silt. Historic fill extends below the cellar floor slab to depths

between about 0.3 and 3 feet below grade surface (bgs) (el. 7.2 to el. 4.5). Historic fill in

the exterior eastern portion of the Site extends to depths from about 30 to 33 feet bgs (el. 7

to el. 4). Bedrock was not encountered during the RI; however, bedrock was encountered

between about 55 and 75 bgs (el. -51.5 to el. -18.5) during a concurrent geotechnical

investigation.

4. Historic fill material generally consists of brown fine sand with traces of silt and gravel

interspersed with concrete, glass and brick fragments. Domestic refuse was observed in

shallow fill material in one boring in the northwestern portion of the cellar. Native soil

generally consisting of brown fine and medium sand with varying amounts of silt underlies

the historic fill. Organic vapor concentrations above background, petroleum-like odors,

staining, or other indications of a chemical or petroleum release were not identified in the

soil samples.

5. Soil/fill sample results were compared to NYSDEC Unrestricted Use (UU) Soil Cleanup

Objectives (SCOs) and Restricted Residential (RR) SCOs as presented in 6NYCRR Part

375-6.8 and CP51. Volatile organic compounds (VOCs) and semivolatile organic

compounds (SVOCs) were detected at or below the UU SCOs. Samples of historical fill

7

material contained the pesticide 4,4’-DDT (max 0.03 mg/kg), and the polychlorinated

biphenyls (PCBs) Aroclor 1254 and Aroclor 1260 (total PCBs 1.11 mg/kg) were detected

at concentrations above the UU SCOs and below the RR SCOs. Four metals, including

lead (max 82.2 mg/kg), mercury (max 0.399 mg/kg), nickel (max 31.9 mg/kg) and zinc

(max 164 mg/kg), were detected at concentrations above the UU SCOs and below the RR

SCOs. Samples of native soil did not contain compounds above the UU SCOs.

6. Groundwater sample results were compared to 6NYCRR Part 703.5 Class GA groundwater

quality standards (GQS). One groundwater sample (MW21) contained chloroform (max 8

µg/l) and tetrachloroethylene (PCE) (max 6.3 µg/l) at concentrations above their respective

GQS. Chloroform is a common byproduct of the chlorination process for drinking water,

and PCE is a chlorinated solvent that was historically used in the commercial dry cleaning

process. Four dissolved metals (antimony, manganese, magnesium, and sodium) were

detected in at least one of the six wells at concentrations above the GQS. The presence of

manganese, magnesium, and sodium in each well indicates that the detections are likely

attributable to a regional groundwater condition. The antimony detection does not correlate

with detections in soil samples from the same boring (EB16) or with detections in other

groundwater samples. The occurrence may therefore reflect a localized condition.

7. Sub-slab soil vapor sample analytical results were evaluated based on the Decision

Matrices presented in the 2006 New York State Department of Health (NYSDOH)

Guidance for Evaluating Soil Vapor Intrusion in the State of New York and the 2013 and

2015 NYSDOH Ambient Air Guideline updates for trichloroethene (TCE) and

tetrachloroethene (PCE). Three of the seven compounds covered by the Decision Matrices

were detected: carbon tetrachloride, TCE, and PCE. The NYSDOH mitigation

recommendations include “no further action” to “monitor” and “mitigate”, based on the

detected soil vapor concentrations.

For more detailed results, consult the RIR. Based on an evaluation of the data and information

from the RIR and this RAWP, disposal of significant amounts of hazardous waste is not

suspected at this site.

2.0 Remedial Action Objectives

Based on the results of the RI, the following Remedial Action Objectives (RAOs) have been

identified for this Site:

Soil

Prevent direct contact with contaminated soil.

Prevent migration of contaminants that would result in groundwater or surface water

contamination.

Groundwater

Prevent direct exposure to contaminated groundwater.

Soil Vapor

Prevent exposure to contaminants in soil vapor.

Prevent migration of soil vapor into dwelling and other occupied structures.

3.0 Remedial Alternatives Analysis

The goal of the remedy selection process is to select a remedy that is protective of human health

and the environment taking into consideration the current, intended and reasonably anticipated

future use of the property. The remedy selection process begins by establishing RAOs for media

in which chemical constituents were found at concentrations greater than applicable standards,

criteria and guidance values (SCGs). Remedial alternatives are then developed and evaluated

based on the following ten criteria:

Protection of human health and the environment;

Compliance with SCGs;

Short-term effectiveness and impacts;

Long-term effectiveness and permanence;

Reduction of toxicity, mobility, or volume of contaminated material;

Implementability;

Cost effectiveness;

Community acceptance;

Land use; and

Sustainability.

As required, a Track 1 Unrestricted Use scenario is evaluated for the remedial action. The

following is a detailed description of the alternatives analyzed to address impacted media at the

Site:

Alternative 1:

Selection of NYSDEC 6NYCRR Part 375 Unrestricted Use (Track 1) SCOs .

Removal of all soil and fill exceeding Track 1 Unrestricted Use SCOs throughout the Site

and confirmation that Track 1 Unrestricted Use SCOs have been achieved with post -

excavation endpoint sampling. Based on the results of the Remedial Investigation, it is

expected that this alternative would be achieved by excavating the entire site footprint to

a minimum elevation of el. 1.0, which is about 6.5 feet below the existing sub-grade level

and about 34 feet below sidewalk grade. Historic fill material extends to a minimum

elevation of about el. 4.5, which is about 3.5 feet above the proposed sub -grade depth.

10

Based on the observations and results of the RI, the proposed excavation will extend to

depths required to achieve Unrestricted Use. If soil/fill containing analytes at

concentrations above Unrestricted Use SCOs is still present at the base of the excavation

after removal of all soil required for construction of the new building's sub-cellar level is

complete, additional excavation will be performed to ensure complete removal of soil/ fill

that does not meet Track 1 Unrestricted Use SCOs .

No Engineering or Institutional Controls are required for a Track 1 cleanup; however, as

part of development, a waterproofing membrane/vapor barrier will be installed beneath

the basement foundation and behind the foundation walls of the new building to prevent

potential exposures from soil vapor intrusion in the future.

Alternative 2:

Establishment of Site-Specific (Track 4) SCOs.

Removal of all soil and fill exceeding Track 4 Site-Specific SCOs throughout the Site and

confirmation that Track 4 Site-Specific SCOs have been achieved with post-excavation

endpoint sampling. Excavation for development purposes would take place to a depth of

approximately 6.5 feet below the existing sub-cellar slab and about 34 feet below existing

sidewalk grade. If soil/fill containing analytes at concentrations above Track 4 Site -

Specific SCOs is still present at the base of the excavation after removal of all soil

required for construction of the new building's sub-cellar level is complete, additional

excavation will be performed to ensure complete removal of soil/ fill that does not meet

Track 4 Site-Specific SCOs.

As part of development, a waterproofing membrane/vapor barrier will be installed

beneath the basement foundation and behind the foundation walls of the new building to

prevent potential exposures from soil vapor in the future.

Placement of a site cover system over the entire site as an engineering control (EC) to

prevent exposure to remaining soil and fill. The system will consist of a concrete

foundation slab within the building footprint.

Establishment of use restrictions (i.e., institutional controls [ICs]) including prohibitions

on the use of groundwater from the Site; prohibitions of restricted Site uses, such as

11

farming or vegetable gardening, to prevent future exposure pathways; and prohibition of

a higher level of land use without OER approval.

Establishment of an approved Site Management Plan (SMP) to ensure long -term

management of these Engineering and Institutional Controls including the performance of

periodic inspections and certification that the controls are performing as they were

intended. The SMP will note that the property owner and property owner’s successors

and assigns must comply with the approved SMP.

The property will continue to be registered with a Restrictive Declaration for Hazardous

Materials.

3.1 Threshold Criteria

Protection of Public Health and the Environment

This criterion is an evaluation of the remedy’s ability to protect public health and the

environment, and an assessment of how risks posed through each existing or potential pathway

of exposure are eliminated, reduced or controlled through removal, treatment, and

implementation of Engineering Controls or Institutional Controls. Protection of public health

and the environment must be achieved for all approved remedial actions.

Alternative 1

Alternative 1 would be protective of human health and the environ ment by removing

contaminated soil and fill exceeding Track 1 SCOs, thus eliminating potential for direct contact

with contaminated soil, and eliminating the risk of contamination leaching into groundwater,

once construction is complete. The construction measure to install a waterproofing

membrane/vapor barrier would mitigate potential risk from soil vapor intrusion from a potential

off-site source.

Alternative 2

Alternative 2 would achieve comparable protections of human health and the environment by

excavation and removal of most of the historic fill at the Site and by ensuring that remaining soil

and fill on-Site meets Track 4 Site-Specific SCO’s , as well as by placement of Institutional and

Engineering Controls, including a composite cover system. The site cover system would prevent

direct contact with any remaining on-Site soil and fill. Implementing Institutional Controls

including a Site Management Plan and continuing the Restrictive Declaration would ensure that

12

the cover system remains intact and protective of public health. Establishment of Track 4 Site-

Specific SCO’s would minimize the risk of contamination leaching into groundwater.

For both Alternatives, potential exposure to contaminated soil or groundwater during

construction would be minimized by implementing a Construction Health and Safety Plan

(CHASP), an approved Soil/Materials Management Plan (SMMP), and Community Air

Monitoring Plan (CAMP). Potential contact with contaminated groundwater would be prevented

as its use is prohibited by city laws and regulations. Potential future migration of off-Site soil

vapors into the new building would be prevented by installing a vapor barrier below the building

slab and outside foundations walls below grade.

3.2 Balancing Criteria

Compliance with Standards, Criteria and Guidance (SCGs)

This evaluation criterion assesses the ability of the alternative to achieve applicable standards,

criteria and guidance.

Alternative 1

Alternative 1 would achieve compliance with the remedial goals, chemical-specific SCGs and

RAOs for soil through removal of soil to achieve Track 1 Unrestricted Use SCOs and Protection

of Groundwater SCOs. Compliance with SCGs for soil vapor would also be achieved by

installing a waterproofing membrane/vapor barrier below the new building's basement slab and

continuing the vapor barrier outside of sub-grade foundation walls, as part of development.

Alternative 2

Alternative 2 would achieve compliance with the remedial goals, chemical-specific SCGs and

RAOs for soil through removal of soil to meet Track 4 Site-Specific SCOs. Compliance with

SCGs for soil vapor would also be achieved by installing a waterproofing membrane/vapor

barrier below the new building's basement slab and continuing the vapor barrier around sub-

grade foundation walls. An SMP would ensure that these controls remained protective for the

long term.

13

Health and safety measures contained in the CHASP and CAMP that comply with the applicable

SCGs shall be implemented during Site redevelopment under this RAWP. For both Alternatives,

focused attention to means and methods employed during the remedial action would ensure that

handling and management of contaminated material would be compliant with applicable SCGs.

These measures will protect on-site workers and the surrounding community from exposure to

site-related contaminants.

Short-Term Effectiveness and Impacts

This evaluation criterion assesses the effects of the alternative during the construction and

implementation phase until remedial action objectives are met. Under this criterion, alternatives

are evaluated with respect to their short term effects during the remedial action on public health

and the environment during implementation of the remedial action, including protection of the

community, protection of onsite workers and environmental impacts.

Alternatives 1 and 2 have similar short-term effectiveness during their respective

implementations, as each requires removal excavation of historic fill material. Both alternatives

would result in short-term dust generation impacts associated with excavation, handling, load out

of materials, and truck traffic. Attention to means and methods during the removal action,

including community air monitoring and appropriate truck routing, would minimize or negate the

overall impact of these activities.

An additional short-term adverse impact and risk to the community associated with both

remedial alternatives is increased truck traffic. About 2,300, 25-ton capacity truck-trips would

be necessary to transport fill and soil excavated during Site development for either Track 1 or

Track 4. Truck traffic will be routed on the most direct course using major thoroughfares where

possible and flag persons will be used to protect pedestrians at Site entrances and exits.

The potential adverse impact to the community, workers and the environment for both

alternatives would be minimized through implementation of control plans including a CHASP, a

CAMP and an SMMP, during all on-Site soil disturbance activities and would minimize the

release of contaminants into the environment. Both alternatives provide short -term effectiveness

in protecting the surrounding community by decreasing the risk of contact with on -Site

contaminants. Construction workers operating under appropriate management procedures and a

14

CHASP would be provided protection from on-Site contaminants by using personal protective

equipment, which would be worn consistent with the documented risks within the respective

work zones.

Long-Term Effectiveness and Permanence

This evaluation criterion addresses the results of a remedial action in terms of its permanence

and quantity/nature of waste or residual contamination remaining at the Site after response

objectives have been met, such as permanence of the remedial alternative, magnitude of

remaining contamination, adequacy of controls including the adequacy and suitability of ECs/ICs

that may be used to manage contaminant residuals that remain at the Site and assessment of

containment systems and ICs that are designed to eliminate exposures to contaminants, and long -

term reliability of ECs.

Alternative 1

The Track 1 remedy would achieve long-term effectiveness and permanence related to on-site

contamination by removing all impacted soil above Track 1 Unrestricted Use SCOs. Removal of

on-site contaminant sources will also minimize future potential groundwater contamination.

Installation of a waterproofing membrane/vapor barrier as a construction measure would prevent

potential future migration of soil vapors from a potential off-Site source into the new building.

Alternative 2

Alternative 2 would provide long-term effectiveness by:

1. Removing soil and fill with contaminant concentrations above Track 4 Site-

Specific SCOs;

2. Constructing a cover system across the Site;

3. Maintaining use restrictions;

4. Establishing an SMP to ensure long-term management of EC/ICs; and

5. Maintaining the hazardous materials Restrictive Declaration to memorialize these

controls for the long-term.

The SMP would provide long-term effectiveness of all EC/ICs by requiring periodic inspection

and certification that these controls and restrictions continue to be in place and functioning as

they were intended. The inspection and certification would document that protections designed

15

into the remedy provide continued protection.

Both alternatives would result in removal of soil contamination exceeding their respective SCOs,

which provides a permanent remedy over the long-term with respect to a remedy for

contaminated soil. This will also eliminate or minimize migration of any potential soil-related

contaminants to groundwater. Installation of a waterproofing membrane/vapor barrier as a

construction measure under both scenarios will mitigate potential sources of soil vapor intrusion.

Reduction of Toxicity, Mobility, or Volume of Contaminated Material

This evaluation criterion assesses the remedial alternative's use of remedial technologies that

permanently and significantly reduce toxicity, mobility, or volume of contaminants as their

principal element. The following is the hierarchy of source removal and control measures that

are to be used to remediate a Site, ranked from most preferable to least preferable: removal

and/or treatment, containment, elimination of exposure and treatment of source at the point of

exposure. It is preferred to use treatment or removal to eliminate contaminants at a Site, reduce

the total mass of toxic contaminants, cause irreversible reduction in contaminant mobility, or

reduce of total volume of contaminated media.

Alternative 1

Alternative 1 will permanently eliminate the toxicity, mobility, and volume of contaminated

material by removing all soil and fill exceeding Track 1 Unrestricted Use SCOs.

Alternative 2

Alternative 2 provides a similar reduction in toxicity, mobility, and volume of contaminated

material through the removal of all historic fill and the removal of any remaining soil exceeding

the Track 4 Site-Specific SCOs.

Implementability

This evaluation criterion addresses the technical and administrative feasibility of implementing

an alternative and the availability of various services and materials required during its

implementation, including technical feasibility of construction and operation, reliability of the

selected technology, ease of undertaking remedial action, monitoring considerations,

administrative feasibility (e.g. obtaining permits for remedial activities), and availability of

services and materials.

16

The techniques, materials and equipment to implement both remedial Alternatives 1 and 2 are

readily available and have been proven effective in remediating the contaminants associated with

the Site. They use standard materials and services that are well established technologies. Each

remedy is reliable. The remedial measures conform to the site development plans; hence, there

are no special difficulties associated with the activities proposed .

Cost Effectiveness

This evaluation criterion addresses the cost of alternatives, including capital costs (such as

construction costs, equipment costs, and disposal costs, engineering expenses) and site

management costs (costs incurred after remedial construction is complete) necessary to ensure

the continued effectiveness of a remedial action.

Since historic fill at the Site was found to extend to a depth of up to about 33 feet below sidewalk

grade during the RI, and the new building requires excavation of the entire Site to a minimum

depth of about 34 feet below sidewalk grade, the costs associated with both Alternative 1 and

Alternative 2 will likely be comparable. Costs associated with Alternative 1 could potentially be

higher than Alternative 2 if soil with analytes above Track 1 Unrestricted Use SCOs is

encountered below the excavation depth required for development. Additional costs would

include disposal of additional soil and import of clean soil for backfill. However, long-term costs

for Alternative 2 are likely higher than Alternative 1 based on implementation of a Site

Management Plan as part of Alternative 2.

The remedial plan would couple the remedial action with the redevelopment of the Site, lowering

total costs. The remedial plan will also consider the selection of the most appropriate disposal

facilities to reduce transportation and disposal costs during cleanup and redevelopment of the

Site.

Community Acceptance

This evaluation criterion addresses community opinion and support for the remedial action.

Observations here will be supplemented by public comment received on the RAWP.

Based on the overall goals of the remedial program and initial permitting associated with the

proposed Site development, no adverse community opinion is anticipated for either alternative.

This RAP will be subject to a public review under the VCP and will provide the opportunity for

detailed public input on the remedial alternatives, and the selected remedy. This public comment

will be considered by OER prior to approval of this plan. The Citizen Participation Plan for the

project is provided in Appendix 3. Observations here will be supplemented by public comment

received on the RAWP. Under both alternatives, the overall goals of the remedial program, to

protect public health and the environment and eliminate potential contaminant exposures, have

been broadly supported by citizens in NYC communities .

Land Use

This evaluation criterion addresses the proposed use of the property. This evaluation has

considered reasonably anticipated future uses of the Site and takes into account: current use and

historical and/or recent development patterns; applicable zoning laws and maps; NYS

Department of State’s Brownfield Opportunity Areas (BOA) pursuant to section 970-r of the

general municipal law; applicable land use plans; proximity to real property currently used for

residential use, and to commercial, industrial, agricultural, and/or recreational areas;

environmental justice impacts, Federal or State land use designations; population growth patterns

and projections; accessibility to existing infrastructure; proximity of the site to important cultural

resources and natural resources, potential vulnerability of groundwater to contamination that

might emanate from the site, proximity to flood plains, geography and geology; and current

Institutional Controls applicable to the site.

The current, intended, and reasonably anticipated future land use of the Site and its surroundings

are compatible with the selected remedy of soil remediation. The proposed future use of the Site

is an NYU-owned and operated facility consisting of a six-story podium that supports five, up to

23-story towers. The facility will contain a cellar and sub-cellar level under the podium. The

new facility will be used for student and faculty housing, commercial space, theaters, dining

areas, performing arts venues, athletic spaces, gymnasium zones and classrooms.

Following remediation, the Site will meet either Track 1 Unrestricted Use SCOs or Track 4 Site-

Specific SCOs, both of which are protective of public health and the environment for its planned

residential use. The proposed use is compliant with the 2012 Restrictive Declaration of Large-

Scale General Development for the NYU LSGD and is consistent with recent development

patterns. Both remediation alternatives are appropriate for the Site’s planned use.

18

The areas surrounding the Site are urban and consist of predominantly mixed residential,

commercial, and institutional buildings in zoning districts designated for commercial and

residential uses. The development would remediate an underutilized lot and provide a modern,

multiple-use recreational, classroom, and student/faculty residential facility. The proposed

development would clean up the property and make it safer, create new employment

opportunities, add living space, and provide economic and fiscal benefits to the city and state in

the form of economic revitalization and tax revenue.

Temporary short-term project impacts are being mitigated through Site management controls and

truck traffic controls during remediation activities.

The adjoining western portion of Lot 66 is occupied by University Village, a complex of three

high-rise apartment buildings. University Village is designated as a Historic Landmark by the

New York City Landmarks Preservation Commission. The Site is not in close proximity to other

important cultural resources, including federal- or state- historic or heritage Sites, Native

American religious Sites, natural resources, waterways, wildlife refuges, wetlands, or critical

habitats of endangered or threatened species. The Site is located in an urban area and not in

proximity to fish or wildlife.

Neither alternative would encroach on the landmarked University Village or result in potential

exposure pathways of contaminant migration affecting fish or wildlife. The remedial action is

also protective of groundwater natural resources. Municipal water supply wells are not present in

this part of City; therefore, groundwater from the Site cannot affect municipal water supply wells

or recharge areas. The Site does not lie in a Federal Emergency Management Agency (FEMA)-

designated flood plain. Both alternatives are equally protective of natural resources and cultural

resources. Improvements in the current environmental condition of the property achieved by

both alternatives are also consistent with the City’s goals for cleanup of contaminated land.

Sustainability of the Remedial Action

This criterion evaluates the overall sustainability of the remedial action alternatives and the

degree to which sustainable means are employed to implement the remedial action including

those that take into consideration NYC’s sustainability goals defined in PlaNYC: A Greener,

Greater New York. Sustainability goals may include: maximizing the recycling and reuse of

19

non-virgin materials; reducing the consumption of virgin and non-renewable resources;

minimizing energy consumption and greenhouse gas emissions; improving energy efficiency;

and promotion of the use of native vegetation and enhancing biodiversity during landscaping

associated with Site development.

While Alternative 2 would potentially result in lower energy usage based on reducing the volume

of material transported off site, both remedial alternatives are comparable with respect to the

opportunity to achieve sustainable remedial action. The remedial plan would take into

consideration the shortest trucking routes during off-site disposal of historic fill and other soil,

which would reduce greenhouse gas emissions and conserve energy used to fuel trucks. The

New York City Clean Soil Bank program is available for reuse of any clean native soils under

either alternative. A complete list of green remedial activities considered as part of the NYC

VCP is included in the Sustainability Statement, included as Appendix 4.

20

4.0 Remedial Action

4.1 Summary of Preferred Remedial Action

The preferred remedial action alternative is Alternative 1, the Track 1 remedial action. The

preferred remedial action achieves protection of public health and the environment for the

intended use of the property. The preferred remedial action will achieve all of the remedial action

objectives established for the project and addresses applicable SCGs. The preferred remedial

action is effective in both the short-term and long-term and reduces mobility, toxicity and

volume of contaminants. The preferred remedial action alternative is cost effective and

implementable and uses standards methods that are well established in the industry.

The proposed remedial action will consist of:

1. Preparation of a Community Protection Statement and performance of all required

NYC VCP Citizen Participation activities according to an approved Citizen

Participation Plan.

2. Performance of a Community Air Monitoring Program for particulates and volatile

organic carbon compounds.

3. Selection of NYSDEC Part 375 Unrestricted Use (Track 1) SCOs.

4. Site mobilization involving Site security setup, equipment mobilization, utility mark

outs and marking & staking excavation areas.

5. Completion of a Waste Characterization Study prior to excavation activities . A Waste

Characterization Study was completed during the RI and additional sampling will be

conducted as required for soil disposal facility approval. Waste characterization soil

samples were collected at a frequency of about one sample per 800 (approximate) cubic

yards of fill to be excavated. A Waste Characterization Report documenting sample

procedures, location and analytical results shall be submitted to OER as part of the

Remedial Action Report (RAR).

6. Excavation and removal of soil and fill exceeding Track 1 Unrestricted Use SCOs

during installation of the temporary support of excavation (SOE) system along the

northern, eastern and western perimeters of the Site. Soldier piles will be drilled to a

depth of about 48 to 50 feet below sidewalk grade (el. -15.0). The eastern and western

exterior portions of the Site will be excavated to the planned sub-grade elevation (el.

21

1.0, which is about 6.5 feet below the existing sub-grade level and about 34 feet below

sidewalk grade. The below-ground portions of the existing building will be demolished

during this phase. Approximately 22,000 cubic yards (CY) of soil will be removed

during the SOE phase.

7. Excavation and removal of soil and fill exceeding Track 1 Unrestricted Use SCOs

during bulk excavation in the footprint of the existing building. The footprint of the

former building will be excavated from the existing level (el. 7.5) to the sub-cellar

foundation slab elevation (el. 1.0), which is about 6.5 feet below the existing sub-grade

level and about 34 feet below sidewalk grade. Deeper excavation will occur in the

areas of the proposed swimming pool (el. -3.3 or about 37.5 feet below sidewalk

grade), the elevator pits (el. -4.7 or about 38.5 feet below sidewalk grade) and caissons

and caps (el. -1.5 and -5.0 or about 35.5 and 39 feet below sidewalk grade).

Approximately 16,000 CY of soil will be removed during this phase.

8. Screening of excavated soil fill during intrusive work for indications of contamination

by visual means, odor, and monitoring with a PID. Appropriate segregation of

excavated media on-Site.

9. Management of excavated materials including temporarily stockpiling and segregating

in accordance with defined material types and to prevent co-mingling of contaminated

material and non-contaminated materials.

10. Removal of underground storage tanks encountered during soil and fill removal.

Registration of tanks , reporting of petroleum spills associated with USTs, and

appropriate closure of these petroleum spills in compliance with applicable local, state

and federal laws and regulations is required for any decommissioned USTs .

11. Transportation and off-Site disposal of all soil and fill material at licensed or permitted

facilities in accordance with applicable laws and regulations for handling, transport, and

disposal, and this plan. Sampling and analysis of excavated media as required by

disposal facilities. Appropriate segregation of excavated media on-Site.

12. Collection and analysis of end-point samples to determine the performance of the

remedy with respect to attainment of Track 1 SCOs. If the initial end-point samples do

not meet Track 1 SCOs, additional excavation will be performed until confirmation of

22

Track 1 attainment is confirmed with supplemental end-point samples or a Track 4

remedy (i.e., Alternative 2) will be implemented in lieu of deeper excavation.

13. Import of materials to be used for backfill and cover in compliance with this plan and in

accordance with applicable laws and regulations.

14. Performance of all activities required for the remedial action, including acquisition of

required permits and attainment of pretreatment requirements, in compliance with

applicable laws and regulations .

15. Dewatering in compliance with city, state, and federal laws and regulations. Extracted

groundwater will either be containerized for off-site disposal at a licensed or permitted

facility or will be treated in accordance with a permit from the New York City

Department of Environmental Protection (NYCDEP) to meet pretreatment

requirements prior to discharge to the sewer system.

16. Implementation of storm-water pollution prevention measures in compliance with

applicable laws and regulations.

17. Submission of a Remedial Action Report (RAR) that describes the remedial activities,

certifies that the remedial requirements have been achieved, defines the Site

boundaries, and lists any changes from this RAWP.

If Track 1 Unrestricted Use SCOs are not achieved, the following construction elements

implemented as part of new development will constitute Engineering and Institutional Controls:

As part of development, construction of an engineered site cover system consisting of an

18-inch thick concrete foundation slab beneath all building areas.

As part of development, installation of a waterproofing membrane/vapor barrier system

consisting of vapor barrier beneath the building slab and outside of sub-grade foundation

sidewalls to mitigate soil vapor migration into the building. The system will consist of a

minimum 20-mil thick vapor barrier. The proposed waterproofing membrane/vapor

barrier will be manufactured by Grace Construction Products and will consist of

PrePrufe® 160 and 300R and Bituthene

® 30000/4000, or similar. All welds, seams and

penetrations will be properly sealed to prevent preferential pathways for vapor migration.

23

4.2 Soil Cleanup Objectives and Soil/ Fill Management

Track 1 SCOs are proposed for this project and SCOs are defined in 6 NYCRR Part 375, Table

6.8(a) Track 1 Unrestricted Use. If Track 1 SCOs are not achieved, the Track 4 Restricted

Commercial SCOs, as defined in 6 NYCRR Part 375, Table 6.8(b) Restricted Commercial Use

will be met.

Soil and materials management on-Site and off-Site, including excavation, handling and

disposal, will be conducted in accordance with the Soil/Materials Management Plan in Appendix

4. Discrete contaminant sources (such as hotspots) identified during the remedial action will be

identified by GPS or surveyed. This information will be provided in the Remedial Action Report.

Soil/Fill Excavation and Removal

The location of planned excavations is shown on Figure 4. Soil and fill removal will occur

during two construction phases. During the first phase, an SOE system consisting of drilled

soldier piles with lagging and tie backs will be installed along the northern, eastern, and western

perimeter of the Site. The soldier piles will be drilled to a depth of about 48 to 50 feet below

sidewalk grade (i.e., about el. -15). Following SOE installation, the exterior portions of the Site

will be excavated to the foundation construction depth, which is about 33 to 35 feet below

sidewalk grade (el. 1.0). The total quantity of soil and fill expected to be excavated and disposed

off-Site during this construction phase is about 33,000 tons.

During the foundation construction phase, the area in the footprint of the existing building will

be excavated to the foundation construction depth, which is about 6.5 feet below the current sub-

grade. Deeper excavation will occur in the areas of the proposed swimming pool (el. -3.3 or

about 37.5 feet below sidewalk grade), the elevator pits (el. -4.7 or about 38.5 feet below

sidewalk grade) and caissons and caps (el. -1.5 and -5.0, or about 35.5 and 39 feet below

sidewalk grade). The total quantity of soil and fill expected to be excavated and disposed off-

Site during this construction phase is about 24,000 tons.

For each disposal facility to be used, a letter from the developer/QEP to the receiving facility

requesting approval for disposal and a letter back to the developer/QEP providing approval for

disposal will be submitted to OER prior to any transport and disposal of soil at a facility.

24

Disposal facilities will be reported to OER when they are identified and prior to the start of

remedial action.

Confirmation End-point Sampling

After removal of historic fill material and soil to the proposed development depth, end point

samples will be collected. In addition to the 12 samples of native soil that were collected during

the RI at the development depth, 6 end point samples will be collected from the base of the

excavation at locations to be determined by OER. To evaluate attainment of Track 1 SCOs,

samples will be analyzed for VOCs, SVOCs, pesticides, PCBs and metals according to analytical

methods described below. If the initial end-point samples do not meet Track 1 SCOs, additional

excavation will be performed until confirmation of Track 1 attainment is confirmed with

supplemental end-point samples or a Track 4 remedy (i.e., Alternative 2) will be implemented in

lieu of deeper excavation. An endpoint sampling diagram is included as Figure5.

End-Point Sample Analyses

End-point samples will be analyzed for compounds and elements as described below utilizing the

following methodology:

Volatile organic compounds by EPA Method 8260;

Semi-volatile organic compounds by EPA Method 8270;

Target Analyte List metals; and

Pesticides/PCBs by EPA Method 8081/8082.

New York State ELAP certified labs will be used for all end-point sample analyses. Labs

performing end-point sample analyses will be reported in the RAR. The RAR will provide a

tabular and map summary of all end-point sample results and will include all data including non-

detects and applicable standards and/or guidance values.

Quality Assurance/Quality Control

The fundamental quality assurance (QA) objective with respect to accuracy, precision, and

sensitivity of analysis for laboratory analytical data is to achieve the QC acceptance of the

analytical protocol. The accuracy, precision and completeness requirements will be addressed by

the laboratory for all data generated.

25

One blind duplicate sample for every 20 samples collected will be submitted to the approved

laboratory for analysis of the same parameters. Trip blanks will be used whenever samples are

transported to the laboratory for analysis of VOCs. One trip blank will be submitted to the

laboratory with each shipment of soil samples. Trip blanks will not be used for samples to be

analyzed for metals, SVOCs or pesticides.

Samples will be appropriately packaged, placed in coolers and shipped via overnight courier or

delivered directly to the analytical laboratory by field personnel. Samples will be containerized

in appropriate laboratory provided glassware and shipped in plastic coolers. Samples will be

preserved through the use of ice or “cold-packs” to maintain a temperature of 4oC.

Dedicated disposable sampling materials will be used for the collection endpoint samples,

eliminating the need to prepare field equipment (rinsate) blanks. If non-disposable equipment is

used, (stainless steel scoop, etc.) field rinsate blanks will be prepared at the rate of one for every

20 samples collected. Decontamination of non-dedicated sampling equipment will consist of:

Gently tap or scrape to remove adhered soil;

Rinse with tap water;

Wash with Alconox® detergent solution and scrub;

Rinse with tap water; and

Rinse with distilled or deionized water.

Field blanks will be prepared by pouring distilled or deionized water over decontaminated

equipment and collecting the water in laboratory provided containers.

Import of Soils

Import of soils onto the property will be performed in conformance with the Soil/Materials

Management Plan in Appendix 4. Imported soil will meet Track 1 SCOs. The building

foundation will cover the excavation area. Placement of imported soil will be limited to a

landscaped area above the western 12-foot extension of the cellar. Reuse of soil that meets the

Track 1 SCOs, if required, will be allowed given there are no observable indications of

contamination (e.g. petroleum staining and odor) and reuse complies with 6 NYCRR Part 360.

A map of soil backfill placement locations will be provided with the Remedial Action Report.

26

Reuse of Onsite Soils

Reuse of onsite soils already onsite will be performed in conformance with the Soil/Materials

Management Plan in Appendix 4. Soil reuse is not planned on this project.

4.3 Engineering Controls

The remedial action will achieve Track 1 Unrestricted Use SCOs and no Engineering Controls

are required. However, the following design elements will be incorporated into the project as part

of the development:

(1) Composite Cover System

(2) Waterproofing Membrane/Soil Vapor Barrier System

If Track 1 is not achieved, these elements will constitute Engineering Controls that will be

employed in the remedial action to address residual contamination remaining at the Site.

Composite Cover System

If Track 1 is not achieved, exposure to residual soil and fill will be prevented by an engineered,

site cover system. This cover system will be comprised of an approximately 18-inch thick

concrete building slab. The composite cover is shown on the attached architectural drawin gs

(Appendix 1). In the event that a landscaped area is constructed on residual Site soil or fill, it

will be capped with a minimum of two feet of fill meeting Track 1 SCOs and top soil or gravel

imported from an approved facility/source. Soil or fill will be imported to the Site in accordance

with the SMMP in Appendix 5. A proposed composite cover design drawing for the project is

provided as Figure 6.

Vapor Barrier System

As a precaution against potential infiltration of soil vapors into the sub-grade building, a

waterproofing membrane/vapor barrier will be installed between the concrete sub-cellar slab and

underlying sub-grade layer, extending along the external walls of the sub-cellar and cellar

portions of the structure from the base of the excavation to surface grade level. The vapor barrier

system will have a minimum thickness of 20 mils. As-built vapor barrier plans will be submitted

with the RAR. Proposed vapor barrier design diagrams and specifications for the types of

27

waterproofing and vapor barrier products to be installed for the project are included in Appendix

6.

4.4 Institutional Controls

A Track 1 remedial action is proposed and Institutional Controls are not required. If a Track 1

remedial action is not achieved, Institutional Controls (ICs) will be incorporated in this remedial

action to manage residual soil/fill and other media and render the Site protective of public health

and the environment. These ICs define the program to operate, maintain, inspect and certify the

performance of Engineering Controls and Institutional Controls on this property. Institutional

Controls would be implemented in accordance with a Site Management Plan included in the final

Remedial Action Report (RAR). Institutional Controls would be:

Continued registration of the Restrictive Declaration for the property. This RAWP

includes a description of all ECs and ICs and summarizes the requirements of the SMP,

which will note that the property owner and property owner’s successors and assigns

must comply with the approved SMP;

Submittal of a SMP in the RAR for approval by OER that provides procedures for

appropriate operation, maintenance, inspection, and certification of ECs and IC’s. SMP

will require that the property owner and property owner’s successors and assigns will

submit to OER a periodic written statement that certifies that: (1) controls employed at

the Site are unchanged from the previous certification or that any changes to the controls

were approved by OER; and, (2) nothing has occurred that impairs the ability of the

controls to protect public health and environment or that constitute a violation or failure

to comply with the SMP. OER retains the right to enter the Site in order to evaluate the

continued maintenance of any controls. This certification shall be submitted at a

frequency to be determine by OER in the SMP and will comply with RCNY §43-

1407(l)(3).

Vegetable gardens and farming on the Site are prohibited in contact with residual soil

materials;

Use of groundwater underlying the Site is prohibited without treatment rendering it safe

for its intended use;

28

All future activities on the Site that will disturb residual material must be conduc ted

pursuant to the soil management provisions in an approved SMP; and

The Site will be used for mixed residential, recreational, and institutional use and will not

be used for a higher level of use without prior approval by OER.

4.5 Site Management Plan

A Track 1 remedial action is proposed and Site Management is not required. If a Track 1

remedial action is not achieved, Site Management will be required and will be the last phase of

remediation. Site Management will begin with the approval of the Remedial Action Report and

issuance of the Notice of Completion (NOC) for the Remedial Action. The Site Management

Plan (SMP) describes appropriate methods and procedures to ensure implementation of all ECs

and ICs that are required by this RAWP. The Site Management Plan is submitted as part of the

RAR but will be written in a manner that allows its use as an independent document. Site

Management continues until terminated in writing by OER. The property owner is responsible

to ensure that all Site Management responsibilities defined in the Site Management Plan are

implemented.

4.6 Qualitative Human Health Exposure Assessment

The objective of the qualitative exposure assessment is to identify potential receptors and

pathways for human exposure to the contaminants of concern (COC) that are present at, or

migrating from, the Site. The identification of exposure pathways describes the route that the

COC takes to travel from the source to the receptor. An identified pathway indicates that the

potential for exposure exists; it does not imply that exposures actually occur.

Data and information reported in the Remedial Investigation Report (RIR) are sufficient to

complete a Qualitative Human Health Exposure Assessment (QHHEA) for this project. As part

of the VCP process, a QHHEA was performed to determine whether the Site poses an existing or

future health hazard to the Site’s exposed or potentially exposed population. The sampling data

from the RI were evaluated to determine whether there is any health risk under current and future

conditions by characterizing the exposure setting, identifying exposure pathways, and evaluating

contaminant fate and transport. This QHHEA was prepared in accordance with Appendix 4B and

29

Section 3.3 (b) 8 of the NYSDEC Draft DER-10 Technical Guidance for Site Investigation and

Remediation.

Known and Potential Contaminant Sources

Known and potential sources were identified during previous investigations at the Site and

include the AOCs that were evaluated during the RI. The AOCs for the Site are summarized

below:

1. Potential PCB-Impacted Soil: A 2011 sub-surface investigation indicated that soil in the

exterior eastern portion of the Site may contain PCBs above the Part 375 Restricted Use

Restricted-Residential (RR) SCOs.

2. Potential Hydraulic Oil Impacts: Potential undetected spills of hydraulic oil from an

elevator may have adversely impacted soil and groundwater.

3. Historic Fill Material: The Site was backfilled with historic fill material from unknown

sources during its development history. Historic fill may include ash, slag, demolition

debris, municipal waste products and organic and inorganic compounds above the RR

SCOs.

4. Historical Site Usage: Potential unreported releases associated with previous uses of the

Site, including vehicle repair and manufacturing facilities, may have adversely impacted

soil, groundwater, and soil vapor.

5. Historical and Current Surrounding Property Usage: Potential unreported releases

associated with a 10,000-gallon fuel oil AST on an eastern adjoining property and

historical usage of surrounding properties, including a Con Edison sub-station and vehicle

repair, dry cleaning, and manufacturing facilities, may have adversely impacted soil vapor

and groundwater at the Site.

Based on the results of the RIR, the contaminants of concern are:

Soil:

Part 375 analytes were not detected at concentrations above the RR SCOs. Multiple

metals (i.e., mercury, lead, zinc, and nickel) and one pesticide, 4,4’-DDT, were detected

at concentrations above the Part 375 Unrestricted Use (UU) SCOs in samples collected

from the upper 10 feet of historic fill material

30

Groundwater:

VOCs including chloroform and PCE were detected above their respective TOGS SGVs.

Dissolved metals including antimony, manganese, magnesium, and sodium, were

detected above the respective TOGS SGVs.

Soil Vapor:

TCE was detected in one sample at a concentration corresponding to recommendations

ranging from “No Further Action” to “Monitor” and “Mitigate”, according to the

NYSDOH Final Guidance on Soil Vapor Intrusion in the State of New York.

31

Nature, Extent, Fate and Transport of Contaminants

Soil and Fill Material

The information compiled during the RI and previous investigations indicated the presence of

historic fill material from surface grade to depths ranging from about 1 to 6 feet below the sub-

cellar floor slab and about 30 to 33 feet below sidewalk grade. The fill material generally

consists of brown fine sand with traces of silt and gravel interspersed with concrete, glass and

brick fragments. Laboratory analytical results from the RI did not identify Part 375 analytes at

concentrations above the RR SCOs. Multiple metals (i.e., mercury, lead, zinc, and nickel) and

one pesticide, 4,4’-DDT, were detected at concentrations above the Part 375 Unrestricted Use

SCOs in samples collected from the upper 10 feet of historic fill material. The detected metals

and 4,4’-DDT are likely indicative of background conditions in the historic fill.

Groundwater

Groundwater samples collected during the RI contained VOCs (chloroform and PCE) and

dissolved metals at concentrations above the TOGS SGVs. Chloroform is a common byproduct

of the chlorination process for drinking water, and PCE is a chlorinated solvent that was

historically used in the commercial dry cleaning process . An on-site source for chloroform or

PCE was not identified, based on the findings of the soil investigation and historical use of the

Site. The detected levels therefore likely reflect localized migration of contaminants from an

off-site source. The metals concentrations are distributed throughout groundwater at the Site and

are therefore likely associated with dissolved, naturally occurring mineral constituents from

regional soil or the quality of the historic fill material.

Soil Vapor

Soil vapor samples collected during the RI contained VOCs. TCE (max. 12 µg/m3) is a soil

vapor contaminant of concern. The source of the TCE in soil vapor appears to be off site, due to

the absence of impacts in soil or groundwater and the localized nature of the detection in a single

sample.

Receptor Populations

On-Site Receptors: The existing building currently vacant and undergoing demolition. Access

to the Site is restricted by a 10-foot high construction fence and a controlled construction

32

entrance. On-site receptors include demolition workers, NYU representatives, and visitors

granted access to the property by NYU. During construction, potential on-site receptors will

include construction workers, NYU representatives and sub-contractors, and NYU-authorized

visitors. If contamination remains under proposed future conditions, potential on-site receptors

would include NYU students, faculty, and personnel, adult and children building residents, and

visitors.

Off-Site Receptors: Potential off-site receptors within a 500 foot radius of the Site include adult

and child residents; commercial and construction workers; pedestrians; and trespassers based on

the following land uses within 500 feet of the Site:

1. Commercial Businesses – There are street-level commercial businesses east of

Mercer Street, west of the adjoining residential building, and south of West Houston

Street. The businesses are expected to remain after completion of the proposed

development project.

2. Residential Buildings –There are currently NYU-owned residential high-rise

buildings located immediately west of the Site and north of the Site across Bleecker

Street. Mixed-use buildings with residential units are located east and south of the

Site across Mercer Street and West Houston Street. The surrounding residential uses

are expected to remain after completion of the development project .

3. Pedestrians and Cyclists – Pedestrian traffic (including cyclists) is currently possible

on Mercer Street to the east, West Houston Street to the south, Bleecker Street to the

north, and the Greene Street Walkway to the west. The traffic will continue after the

development project is complete.

4. Schools – According to NYCityMap (i.e., New York City GIS), there are no schools

within 500 feet of the Site.

Potential Routes of Exposure

Three potential primary routes exist by which chemicals can enter the body: ingestion,

inhalation, and dermal absorption. Exposure can occur based on the following potential

exposure pathways:

• Ingestion of groundwater or fill/soil;

• Inhalation of vapors or particulates; and

33

• Dermal absorption of groundwater or fill/soil.

Potential Exposure Points

Current Conditions: The area within the footprint of the existing building is currently capped

with an approximately five-inch thick concrete sub-cellar slab, and there are no potential

exposure pathways from ingestion, inhalation, or dermal absorption of soil/fill in that area. The

eastern exterior portion of the Site is currently being used as a construction staging area for site

demolition. The concrete pavement has been removed and historic fill is exposed in the

southeastern corner of the Site. Potential exposure pathways to construction workers in that area

include inhalation of vapors or particulates, ingestion of fill/soil, and dermal absorption of

fill/soil. Soil disturbance in the exposed area is limited to vehicle and foot traffic; excavation or

other earthwork is not occurring during the demolition phase of work. Site access is restricted to

construction workers and NYU-authorized personnel, and potential exposure to the general

public is therefore restricted.

Groundwater is not exposed at the site. The site is served by the public water supply and

groundwater is not used at the site for potable supply and there is no potential for exposure.

Potential soil vapor accumulation may occur underneath the sub-cellar floor slab. Potential

exposure to soil vapor is limited due to restricted site access during demolition and forthcoming

construction activities.

Construction/ Remediation Conditions: During the remedial action, onsite workers will come

into direct contact with surface and subsurface soil as a result of on-Site construction and

excavation. On-Site construction workers potentially could ingest, inhale or have dermal contact

with exposed impacted soil and fill. Similarly, off-Site receptors could be exposed to dust and

vapors from on-Site activities. Due to the depth of groundwater, direct contact with groundwater

will be limited to excavation within the swimming pool, elevator pit, and cais son areas. During

construction, on-Site and off-Site exposures to contaminated dust from on-Site will be addressed

through the Soil/Materials Management Plan, dust controls, and through the implementation of

the Community Air Monitoring Program and a Construction Health and Safety Plan.

Proposed Future Conditions: Under future remediated conditions, all soils in excess of Track 1

SCOs will be removed. The site will be fully capped, preventing potential direct exposure to soil

34

and groundwater remaining in place. A waterproofing membrane/soil vapor barrier will prevent

any potential exposure due to inhalation by preventing soil vapor intrusion. The Site is served by

the public water supply, and groundwater is not used at the site. There are no plausible off-site

pathways for oral, inhalation, or dermal exposure to contaminants derived from the Site.

Overall Human Health Exposure Assessment

Under current conditions, on-Site exposure pathways exist for those with access to the Site and

trespassers. There are potential complete exposure pathways that require mitigation during

implementation of the remedy. There are no complete exposure pathways under future

conditions after the site is developed. This assessment takes into consideration the reasonably

anticipated use of the Site, which includes residential, recreational, and educational use,

landscaped areas, a concrete sub-cellar floor slab, and a waterproofing membrane/vapor barrier.

During remedial construction, on-Site and off-Site exposures to dust from historic fill material

will be addressed through dust controls, and through the implementation of the Community Air

Monitoring Program, the Soil/Materials Management Plan, and a Construction Health and Safety

Plan. Potential post-construction use of groundwater is not considered an option because

groundwater in this area of New York City is not used as a potable water source. There are no

surface waters in close proximity to the Site that could be impacted or threatened.

5.0 Remedial Action Management

5.1 Project Organization and Oversight

Principal personnel who will participate in the remedial action include the following:

Stuart Knoop, P.G. – Project Manager (Langan)

Michael Burke, CHMM, LEED AP – Qualified Environmental Professional (QEP) for

the project and Senior Associate (Langan)

Jason Hayes, P.E. – Professional Engineer for the project and Senior Associate (Langan).

5.2 Site Security

Site access will be controlled by 24-hour security, construction fencing, and gated construction

entrances .

5.3 Work Hours

The hours for operation of cleanup will comply with the NYC Department of Buildings (DOB)

construction code requirements, the terms of the Restrictive Declaration, or according to specific

variances issued by the NYC DOB. The hours of operation will be conveyed to OER during the

pre-construction meeting.

5.4 Construction Health and Safety Plan

The Health and Safety Plan is included in Appendix 6. The Site Safety Coordinator for Langan

will be William Bohrer. Contractors working at the Site will designate their respective Site

Safety Coordinator. Remedial work performed under this RAWP will be in full compliance with

applicable health and safety laws and regulations, including Site and OSHA worker safety

requirements and HAZWOPER requirements. Confined space entry, if any, will comply with

OSHA requirements and industry standards and will address potential risks. The parties

performing the remedial construction work will ensure that performance of work is in

compliance with the HASP and applicable laws and regulations. The CHASP pertains to

remedial and invasive work performed at the Site until the issuance of the Notice of Completion.

36

All field personnel involved in remedial activities will participate in training required under 29

CFR 1910.120, such as 40-hour hazardous waste operator training and annual 8-hour refresher

training. The Site Safety Officer will be responsible for maintaining workers training records.

Personnel entering any exclusion zone will be trained in the provisions of the CHASP and will

comply with all requirements of 29 CFR 1910.120. Site-specific training will be provided to

field personnel. Additional safety training may be added depending on the tasks performed.

Emergency telephone numbers will be posted at the site location before any remedial work

begins. A safety meeting will be conducted before each shift begins. Topics to be discussed

include task hazards and protective measures (physical, chemical, environmental); emergency

procedures; PPE levels and other relevant safety topics. Meetings will be documented in a log

book or specific form.

An emergency contact sheet with names and phone numbers is included in the CHASP. That

document will define the specific project contacts for use in case of emergency.

5.5 Community Air Monitoring Plan

Real-time air monitoring for volatile organic compounds (VOCs) and particulate levels at the

perimeter of the exclusion zone or work area will be performed. Continuous monitoring will be

performed for all ground intrusive activities and during the handling of contaminated or

potentially contaminated media. Ground intrusive activities include, but are not limited to,

soil/waste excavation and handling, test pit excavation or trenching, and the installation of soil

borings or monitoring wells.

Periodic monitoring for VOCs will be performed during non-intrusive activities such as the

collection of soil and sediment samples or the collection of groundwater samples from existing

monitoring wells. Periodic monitoring during sample collection, for instance, will consist of

taking a reading upon arrival at a sample location, monitoring while opening a well cap or

overturning soil, monitoring during well bailing/purging, and taking a reading prior to leaving a

sample location. Depending upon the proximity of potentially exposed individuals, continuous

monitoring may be performed during sampling activities. Examples of such situations include

groundwater sampling at wells on the curb of a busy urban s treet, in the midst of a public park,

or adjacent to a school or residence. Exceedances of action levels observed during performance

37

of the Community Air Monitoring Plan (CAMP) will be reported to the OER Project Manager

and included in the Daily Report.

VOC Monitoring, Response Levels, and Actions

Volatile organic compounds (VOCs) will be monitored at the downwind perimeter of the

immediate work area (i.e., the exclusion zone) on a continuous basis during invasive work.

Upwind concentrations will be measured at the start of each workday and periodically thereafter

to establish background conditions. The monitoring work will be performed using equipment

appropriate to measure the types of contaminants known or suspected to be present. The

equipment will be calibrated at least daily for the contaminant(s) of concern or for an appropriate

surrogate. The equipment will be capable of calculating 15-minute running average

concentrations, which will be compared to the levels specified below.

• If the ambient air concentration of total organic vapors at the downwind perimeter of the

work area or exclusion zone exceeds 5 parts per million (ppm) above background for the

15-minute average, work activities will be temporarily halted and monitoring continued.

If the total organic vapor level readily decreases (per instantaneous readings) below 5

ppm over background, work activities will resume with continued monitoring.

• If total organic vapor levels at the downwind perimeter of the work area or exclusion

zone persist at levels in excess of 5 ppm over background but less than 25 ppm, work

activities will be halted, the source of vapors identified, corrective actions taken to abate

emissions, and monitoring continued. After these steps, work activities will resume

provided that the total organic vapor level 200 feet downwind of the exclusion zone or

half the distance to the nearest potential receptor or residential/commercial structure,

whichever is less - but in no case less than 20 feet, is below 5 ppm over background for

the 15-minute average.

• If the organic vapor level is above 25 ppm at the perimeter of the work area, activities

will be shutdown.

All 15-minute readings must be recorded and be available for OER personnel to review.

Instantaneous readings, if any, used for decision purposes will also be recorded.

38

Particulate Monitoring, Response Levels, and Actions

Particulate concentrations will be monitored continuously at the upwind and downwind

perimeters of the exclusion zone at temporary particulate monitoring stations. The particulate

monitoring will be performed using real-time monitoring equipment capable of measuring

particulate matter less than 10 micrometers in size (PM-10) and capable of integrating over a

period of 15 minutes (or less) for comparison to the airborne particulate action level. The

equipment will be equipped with an audible alarm to indicate exceedance of the action level. In

addition, fugitive dust migration should be visually assessed during all work activities.

• If the downwind PM-10 particulate level is 100 micrograms per cubic meter (mcg/m3)

greater than background (upwind perimeter) for the 15-minute period or if airborne dust

is observed leaving the work area, then dust suppression techniques will be employed.

Work will continue with dust suppression techniques provided that downwind PM-10

particulate levels do not exceed 150 mcg/m3 above the upwind level and provided that no

visible dust is migrating from the work area.

• If, after implementation of dust suppression techniques, downwind PM-10 particulate

levels are greater than 150 mcg/m3 above the upwind level, work will be stopped and a

re-evaluation of activities initiated. Work will resume provided that dust suppression

measures and other controls are successful in reducing the downwind PM-10 particulate

concentration to within 150 mcg/m3 of the upwind level and in preventing visible dust

migration.

All readings will be recorded and be available for OER personnel to review.

5.6 Agency Approvals

All permits or government approvals required for remedial construction have been or will be

obtained prior to the start of remedial construction. Approval of this RAWP by OER does not

constitute satisfaction of these requirements and will not be a substitute for any required permit.

39

5.7 Site Preparation

Pre-Construction Meeting

OER will be invited to attend the pre-construction meeting at the Site with all parties involved in

the remedial process prior to the start of remedial construction activities.

Mobilization

Mobilization will be conducted as necessary for each phase of work at the Site. Mobilization

includes field personnel orientation, equipment mobilization (including securing all sampling

equipment needed for the field investigation), marking/staking sampling locations and utility

mark-outs. Each field team member will attend an orientation meeting to become familiar with

the general operation of the Site, health and safety requirements, and field procedures.

Utility Marker Layouts, Easement Layouts

The presence of utilities and easements on the Site will be fully investigated prior to the

performance of invasive work such as excavation or drilling under this plan by using, at a

minimum, the One-Call System (811). Underground utilities may pose an electrocution,

explosion, or other hazard during excavation or drilling activities. All invasive activities will be

performed incompliance with applicable laws and regulations including NYC Building Code to

assure safety. Utility companies and other responsible authorities will be contacted to locate and

mark the locations, and a copy of the Mark-Out Ticket will be retained by the contractor prior to

the start of drilling, excavation or other invasive subsurface operations. Overhead utilities may

also be present within the anticipated work zones. Electrical hazards associated with drilling in

the vicinity of overhead utilities will be prevented by maintaining a safe distance between

overhead power lines and drill rig masts.

Proper safety and protective measures pertaining to utilities and easements, and compliance with

all laws and regulations will be employed during invasive and other work contemplated under

this RAWP. The integrity and safety of on-Site and off-Site structures will be maintained during

all invasive, excavation or other remedial activity performed under the RAWP.

40

Dewatering

Dewatering is anticipated during remediation and construction occurring in the proposed

swimming pool, elevator pit, and caisson areas. Dewatering will be completed in accordance

with a NYCDEP permit. As part of the permit process, additional groundwater samples will be

collected and be analyzed for NYCDEP dewatering parameters. All dewatering will be

conducted in accordance with NYCDEP regulations regarding discharge to the municipal sewer

(including appropriate groundwater sampling and permitting) and NYSDEC regulations

regarding groundwater discharge. There shall be no discharge of groundwater onto or into the

Site, unless it has been shown by sampling and laboratory analysis to meet the requirements of

the TOGS SGVs. A copy of the NYCDEP or NYSDEC sewer discharge permit will be included

in the PE-certified RAR submitted to OER.

Equipment and Material Staging

Equipment and materials will be stored and staged in a manner that complies with applicable

laws and regulations.

Stabilized Construction Entrance

Steps will be taken to ensure that trucks departing the site will not track soil, fill or debris off-

Site. Such actions may include use of cleaned asphalt or concrete pads or use of stone or other

aggregate-based egress paths between the truck inspection station and the property exit.

Measures will be taken to ensure that adjacent roadways will be kept clean of project related

soils, fill and debris.

Truck Inspection Station

An outbound-truck inspection station will be set up close to the Site exit. Before exiting the Site,

trucks will be required to stop at the truck inspection station and will be examined for evidence

of contaminated soil on the undercarriage, body, and wheels. Soil and debris will be removed.

Brooms, shovels and clean water will be utilized for the removal of soil from vehicles and

equipment, as necessary.

41

Extreme Storm Preparedness and Response Contingency Plan

Damage from flooding or storm surge can include dislocation of soil and stockpiled materials,

dislocation of site structures and construction materials and equipment, and dislocation of

support of excavation structures. Damage from wind during an extreme storm event can create

unsafe or unstable structures, damage safety structures and cause downed power lines creating

dangerous site conditions and loss of power. In the event of emergency conditions caused by an

extreme storm event, the enrollee will undertake the following steps for site preparedness prior to

the event and response after the event.

Storm Preparedness

Preparations in advance of an extreme storm event will include the following: containerized

hazardous materials and fuels will be removed from the property; loose materials will be secured

to prevent dislocation and blowing by wind or water; heavy equipment such as excavators and

generators will be removed from excavated areas, trenches and depressions on the property to

high ground or removed from the property; an inventory of the property with photographs will be

performed to establish conditions for the site and equipment prior to the event; stockpile covers

for soil and fill will be secured by adding weights such as sandbags for added security and worn

or ripped stockpile covers will be replaced with competent covers; stockpiled hazardous wastes

will be removed from the property; stormwater management systems will be inspected and

fortified, including, as necessary: clean and reposition silt fences, hay bales; clean storm sewer

filters and traps; and secure and protect pumps and hosing.

Storm Response

At the conclusion of an extreme storm event, as soon as it is safe to access the property, a

complete inspection of the property will be performed. A site inspection report will be submitted

to OER at the completion of site inspection and after the site security is assessed. Site conditions

will be compared to the inventory of site conditions and material performed prior to the storm

event and significant differences will be noted. Damage from s torm conditions that result in

acute public safety threats, such as downed power lines or imminent collapse of buildings,

structures or equipment will be reported to public safety authorities via appropriate means such

as calling 911. Petroleum spills will be reported to NYS DEC within 2 hours of identification

42

and consistent with State regulations. Emergency and spill conditions will also be reported to

OER. Public safety structures, such as construction security fences will be repaired promptly to

eliminate public safety threats. Debris will be collected and removed. Dewatering will be

performed in compliance with existing laws and regulations and consistent with emergency

notifications, if any, from proper authorities. Eroded areas of soil including unsafe slopes will be

stabilized and fortified. Dislocated materials will be collected and appropriately managed.

Support of excavation structure will be inspected and fortified as necessary. Impacted stockpiles

will be contained and damaged stockpile covers will be replaced. Stormwater control systems

and structures will be inspected and maintained as necessary. If soil or fill materials are

discharged off site to adjacent properties, property owners and OER will be notified and

corrective measure plan designed to remove and clean dislocated material will be submitted to

OER and implemented following approval by OER and granting of site access by the property

owner. Impacted offsite areas may require characterization based on site conditions, at the

discretion of OER. If onsite petroleum spills are identified, a qualified environmental

professional will determine the nature and extent of the spill and report to NYS DEC’s spill

hotline at DEC 800-457-7362 within statutory defined timelines . If the source of the spill is

ongoing and can be identified, it should be stopped if this can be done safely. Potential hazards

will be addressed immediately, consistent with guidance issued by NYS DEC.

Storm Response Reporting

A site inspection report will be submitted to OER at the completion of site inspection. An

inspection report established by OER is available on OER’s website (www.nyc.gov/oer) and will

be used for this purpose. Site conditions will be compared to the inventory of site conditions and

material performed prior to the storm event and significant differences will be noted. The site

inspection report will be sent to the OER project manager and will include the site name,

address, tax block and lot, site primary and alternate contact name and phone number. Damage

and soil release assessment will include: whether the project had stockpiles; whether stockpiles

were damaged; photographs of damage and notice of plan for repair; report of whether soil from

the site was dislocated and whether any of the soil left the site; estimates of the volume of soil

that left the site, nature of impact, and photographs; description of erosion damage; description

of equipment damage; description of damage to the remedial program or the construction

43

program, such as damage to the support of excavation; presence of onsite or offsite exposure

pathways caused by the storm; presence of petroleum or other spills and status of spill reporting

to NYS DEC; description of corrective actions; schedule for corrective actions. This report

should be completed and submitted to OER project manager with photographs within 24 hours of

the time of safe entry to the property after the storm event.

5.8 Traffic Control

Drivers of trucks leaving the Site with soil/fill will be instructed to proceed without stopping in

the vicinity of the Site to prevent neighborhood impacts. The planned route on local roads for

trucks leaving the site is shown on Figure 7.

5.9 Demobilization

Demobilization will include:

• As necessary, restoration of temporary access areas and areas that may have been

disturbed to accommodate support areas (e.g., staging areas, decontamination areas,

storage areas, temporary water management areas, and access area);

• Removal of sediment from erosion control measures and truck wash and disposal of

materials in accordance with applicable laws and regulations;

• Equipment decontamination, and;

• General refuse disposal.

Equipment will be decontaminated and demobilized at the completion of all field activities.

Investigation equipment and large equipment (e.g., soil excavators) will be washed at the truck

inspection station as necessary. In addition, all investigation and remediation derived waste will

be appropriately disposed.

5.10 Reporting and Record Keeping

Daily reports

Daily reports providing a general summary of activities for each day of active remedial work will

be emailed to the OER Project Manager by the end of the following business day. Those reports

will include:

44

to the RAWP or other sensitive or time critical information. However, such information will be

included in the daily reports. Emergency conditions and changes to the RAWP will be

communicated directly to the OER project manager by personal communication. Daily reports

will be included as an Appendix in the Remedial Action Report.

Record Keeping and Photo Documentation

Job-site record keeping for all remedial work will be performed. These records will be

maintained on-Site during the project and will be available for inspection by OER staff.

Representative photographs will be taken of the Site prior to any remedial activities and during

major remedial activities to illustrate remedial program elements and contaminant source areas.

Photographs will be submitted at the completion of the project in the RAR in digital format (i.e.

jpeg files).

5.11 Complaint Management

All complaints from citizens will be promptly reported to OER. Complaints relating to the

cleanup will be addressed and outcomes will also be reported to OER in daily reports. Notices to

OER will include the nature of the complaint, the party providing the complaint, and the actions

taken to resolve any problems.

45

5.12 Deviations from the Remedial Action Work Plan

All changes to the RAWP will be reported to, and approved by, the OER Project Manager and

will be documented in daily reports and reported in the Remedial Action Report. The process to

be followed if there are any deviations from the RAWP will include a request for approval for

the change from OER noting the following:

• Reasons for deviating from the approved RAWP;

• Effect of the deviations on overall remedy; and

• Determination with basis that the remedial action with the deviation(s) is protective of

public health and the environment.

46

APPENDIX 3

CITIZEN PARTICIPATION PLAN

The NYC Office of Environmental Remediation and New York University (NYU) have

established this Citizen Participation Plan because the opportunity for citizen participation is an

important component of the NYC Voluntary Cleanup Program. This Citizen Participation Plan

describes how information about the project will be disseminated to the Community during the

remedial process. As part of its obligations under the NYC VCP, NYU will maintain a

repository for project documents and provide public notice at specified times throughout the

remedial program. This Plan also takes into account potential environmental justice concerns in

the community that surrounds the project Site. Under this Citizen Participation Plan, project

documents and work plans are made available to the public in a timely manner. Public comment

on work plans is strongly encouraged during public comment periods. Work plans are not

approved by the NYC Office of Environmental Remediation (OER) until public comment

periods have expired and all comments are formally reviewed. An explanation of cleanup plans

in the form of a public meeting or informational session is available upon request to OER’s

project manager assigned to this Site, Horace Zhang, who can be contacted about these issues or

any others questions, comments or concerns that arise during the remedial process at (212) 788-

8484.

Project Contact List: OER has established a Site Contact List for this project to provide

public notices in the form of fact sheets to interested members of the Community.

Communications will include updates on important information relating to the progress of the

cleanup program at the Site as well as to request public comments on the cleanup plan. The

Project Contact List includes owners and occupants of adjacent buildings and homes, principal

administrators of nearby schools, hospitals and day care centers, the public water supplier that

serves the area, established document repositories, the representative Community Board, City

Council members, other elected representatives and any local Brownfield Opportunity Area

2

(BOA) grantee organizations. Any member of the public or organization will be added to the

Site Contact List on request. A copy of the Site Contact List is maintained by OER’s project

manager. If you would like to be added to the Project Contact List, contact NYC OER at (212)

788-8841 or by email at brownfields@cityhall.nyc.gov.

Repositories: A document repository is maintained online. Internet access to view OER’s

document repositories is available at public libraries. This document repository is intended to

house, for community review, all principal documents generated during the cleanup program

including Remedial Investigation plans and reports, Remedial Action work plans and reports,

and all public notices and fact sheets produced during the lifetime of the remedial project. The

library nearest the Site is:

Mulberry Street Library

10 Jersey Street

New York, New York 10012

(212) 966-3424

M-Th: 10AM-7PM; F-S: 10AM-5PM; closed Sundays

Digital Documentation: NYC OER requires the use of digital documents in our repository

as a means of minimizing paper use while also increasing convenience in access and ease of use.

Issues of Public Concern: There are no environmental justice or other specific issues of

public concern related to the RAWP.

Public Notice and Public Comment: Public notice to all members of the Project Contact

List is required at three major steps during the performance of the cleanup program (listed

below) and at other points that may be required by OER. Notices will include Fact Sheets with

descriptive project summaries, updates on recent and upcoming project activities, repository

information, and important phone and email contact information. All notices will be reviewed

and approved by OER prior to distribution and mailed by the Enrollee. Public comment is

solicited in public notices for all work plans developed under the NYC Voluntary Cleanup

3

Program. Final review of all work plans by OER will consider all public comments. Approval

will not be granted until the public comment period has been completed.

Citizen Participation Milestones: Public notice and public comment activities occur at

several steps during a typical NYC VCP project. These steps include:

• Public Notice of the availability of the Remedial Investigation Report and Remedial

Action Work Plan and a 30-day public comment period on the Remedial Action

Work Plan: Public notice in the form of a Fact Sheet is sent to all parties listed on the

Site Contact List announcing the availability of the Remedial Investigation Report and

Remedial Action Work Plan and the initiation of a 30-day public comment period on the

Remedial Action Work Plan. The Fact Sheet summarizes the findings of the RIR and

provides details of the RAWP. The public comment period will be extended an

additional 15 days upon public request. A public meeting or informational session will

be conducted by OER upon request.

• Public Notice announcing the approval of the RAWP and the start of remediation:

Public notice in the form of a Fact Sheet is sent to all parties listed on the Site Contact

List announcing the approval of the RAWP and the start of remediation.

• Public Notice announcing the completion of remediation, designation of

Institutional and Engineering Controls and issuance of the Notice of Completion:

Public notice in the form of a Fact Sheet is sent to all parties listed on the Site Contact

List announcing the completion of remediation, providing a list of all Institutional and

Engineering Controls implemented for to the Site and announcing the issuance of the

Notice of Completion.

APPENDIX 4

Sustainability Statement

1

APPENDIX 4

SUSTAINABILITY STATEMENT

This Sustainability Statement documents sustainable activities and green remediation efforts

planned under this remedial action.

Reuse of Clean, Recyclable Materials and Reduced Consumption of Non-

Renewable Resources:

Reuse of clean, locally-derived recyclable materials reduces consumption of non-renewable

virgin resources and can provide energy savings and greenhouse gas reduction.

An estimate of the quantity (in tons) of clean, non-virgin materials (reported by type of material)

reused under this plan will be quantified and reported in the RAR.

Reduced Energy Consumption and Promotion of Greater Energy Efficiency:

Reduced energy consumption lowers greenhouse gas emissions, improves local air quality,

lessens in-city power generation requirements, can lower traffic congestion, and provides

substantial cost savings.

Best efforts will be made to quantify energy efficiencies achieved during the remediation and

will be reported in the RAR. Where energy savings cannot be easily quantified, a gross indicator

of the amount of energy saved or the means by which energy savings was achieved will be

reported.

Conversion to Clean Fuels:

Use of clean fuel improves NYC’s air quality by reducing harmful emissions.

An estimate of the volume of clean fuels used during remedial activities will be quantified and

reported in the RAR.

2

Recontamination Control:

Recontamination after cleanup and redevelopment is completed undermines the value of work

performed, may result in a property that is less protective of public health or the environment,

and may necessitate additional cleanup work later or impede future redevelopment.

Recontamination can arise from future releases that occur within the property or by influx of

contamination from off-Site.

An estimate of the area of the Site that utilizes recontamination controls under this plan will be

reported in the RAR in square feet.

Stormwater Retention:

Stormwater retention improves water quality by lowering the rate of combined stormwater and

sewer discharges to NYC’s sewage treatment plants during periods of precipitation, and reduces

the volume of untreated influent to local surface waters.

An estimate of the enhanced stormwater retention capability of the redevelopment project will be

included in the RAR.

Linkage with Green Building: Green buildings provide a multitude of benefits to the city

across a broad range of areas, such as reduction of energy consumption, conservation of

resources, and reduction in toxic materials use.

The number of Green Buildings that are associated with this brownfield redevelopment property

will be reported in the RAR. The total square footage of green building space created as a

function of this brownfield redevelopment will be quantified for residential, commercial and

industrial/manufacturing uses.

Paperless Voluntary Cleanup Program: New York University (NYU) is participating

in OER’s Paperless Voluntary Cleanup Program. Under this program, submission of electronic

documents will replace submission of hard copies for the review of project documents,

communications and milestone reports.

3

Low-Energy Project Management Program: NYU is participating in OER’s low-

energy project management program. Under this program, whenever possible, meetings are held

using remote communication technologies, such as videoconferencing and teleconferencing to

reduce energy consumption and traffic congestion associated with personal transportation.

Trees and Plantings: Trees and other plantings provide habitat and add to NYC’s

environmental quality in a wide variety of ways. Native plant species and native habitat provide

optimal support to local fauna, promote local biodiversity, and require less maintenance.

An estimate of the land area that will be vegetated, including the number of trees planted or

preserved, will be reported in square feet in the RAR.

APPENDIX 5

Soil/Materials Management Plan

1

APPENDIX 5

SOIL/MATERIALS MANAGEMENT PLAN

1.1 Soil Screening Methods

Visual, olfactory and PID soil screening and assessment will be performed under the supervision

of a Qualified Environmental Professional and will be reported in the final remedial report. Soil

screening will be performed during invasive work performed during the remedy and

development phases prior to issuance of final signoff by OER.

1.2 Stockpile Methods

Excavated soil from suspected areas of contamination (e.g., hot spots, USTs, drains, etc.) will be

stockpiled separately and will be segregated from clean soil and construction materials.

Stockpiles will be used only when necessary and will be removed as soon as practicable. While

stockpiles are in place, they will be inspected daily, and before and after every storm event.

Results of inspections will be recorded in a logbook and maintained at the Site and available for

inspection by OER. Excavated soils will be stockpiled on, at minimum, double layers of 8-mil

minimum sheeting, will be kept covered at all times with appropriately anchored plastic tarps,

and will be routinely inspected. Broken or ripped tarps will be promptly replaced.

All stockpile activities will be compliant with applicable laws and regulations. Soil stockpile

areas will be appropriately graded to control run-off in accordance with applicable laws and

regulations. Stockpiles of excavated soils and other materials shall be located at least 50 feet

from the property boundaries, where possible. Hay bales or equivalent will surround soil

stockpiles except for areas where access by equipment is required. Silt fencing and hay bales will

be used as needed near catch basins, surface waters and other discharge points.

1.3 Characterization of Excavated Materials

Soil/fill or other excavated media that is transported off-Site for disposal will be sampled in a

manner required by the receiving facility, and in compliance with applicable laws and

regulations. Soils proposed for reuse on-Site will be managed as defined in this plan.

2

1.4 Materials Excavation, Load-Out, and Departure

The PE/QEP overseeing the remedial action will:

• oversee remedial work and the excavation and load-out of excavated material;

• ensure that there is a party responsible for the safe execution of invasive and other work

performed under this work plan;

• ensure that Site development activities and development-related grading cuts will not

interfere with, or otherwise impair or compromise the remedial activities proposed in this

RAWP;

• ensure that the presence of utilities and easements on the Site has been investigated and

that any identified risks from work proposed under this plan are properly addressed by

appropriate parties;

• ensure that all loaded outbound trucks are inspected and cleaned if necessary before

leaving the Site;

• ensure that all egress points for truck and equipment transport from the Site will be kept

clean of Site-derived materials during Site remediation.

Locations where vehicles exit the Site shall be inspected daily for evidence of soil tracking off

premises. Cleaning of the adjacent streets will be performed as needed to maintain a clean

condition with respect to Site-derived materials.

Open and uncontrolled mechanical processing of historical fill and contaminated soil on-Site will

not be performed without prior OER approval.

1.5 Off-Site Materials Transport

Loaded vehicles leaving the Site will comply with all applicable materials transportation

requirements (including appropriate covering, manifests, and placards) in accordance with

applicable laws and regulations, including use of licensed haulers in accordance with 6 NYCRR

Part 364. If loads contain wet material capable of causing leakage from trucks, truck liners will

be used. Queuing of trucks will be performed on-Site, when possible in order to minimize off

Site disturbance. Off-Site queuing will be minimized.

3

Outbound truck transport routes are described in the remedial report. This routing takes into

account the following factors: (a) limiting transport through residential areas and past sensitive

sites; (b) use of mapped truck routes; (c) minimizing off-Site queuing of trucks entering the

facility; (d) limiting total distance to major highways; (e) promoting safety in access to

highways; and (f) overall safety in transport. To the extent possible, all trucks loaded with Site

materials will travel from the Site using these truck routes. Trucks will not stop or idle in the

neighborhood after leaving the project Site.

1.6 Materials Disposal Off-Site

The following documentation will be established and reported by the PE/QEP for each disposal

destination used in this project to document that the disposal of regulated material exported from

the Site conforms with applicable laws and regulations: (1) a letter from the PE/QEP or Enrollee

to each disposal facility describing the material to be disposed and requesting written acceptance

of the material. This letter will state that material to be disposed is regulated material generated

at an environmental remediation Site in New York City under a governmental remediation

program. The letter will provide the project identity and the name and phone number of the

PE/QEP or Enrollee. The letter will include as an attachment a summary of all chemical data for

the material being transported; and (2) a letter from each disposal facility stating it is in receipt of

the correspondence (1, above) and is approved to accept the material. These documents will be

included in the final remedial report.

The Remedial Action Report will include an itemized account of the destination of all material

removed from the Site during this remedial action. Documentation associated with disposal of

all material will include records and approvals for receipt of the material. This information will

be presented in the final remedial report.

All impacted soil/fill or other waste excavated and removed from the Site will be managed as

regulated material and will be disposed in accordance with applicable laws and regulations.

Historic fill and contaminated soils taken off-Site will be handled as solid waste and will not be

disposed at a Part 360-16 Registration Facility (also known as a Soil Recycling Facility).

Waste characterization will be performed for off-Site disposal in a manner required by the

receiving facility and in conformance with its applicable permits. Waste characterization

sampling and analytical methods, sampling frequency, analytical results and QA/QC will be

4

reported in the final remedial report. A manifest system for off-Site transportation of exported

materials will be employed. Manifest information will be reported in the final remedial report.

Hazardous wastes derived from on-Site will be stored, transported, and disposed of in

compliance with applicable laws and regulations.

If disposal of soil/fill from this Site is proposed for unregulated disposal (i.e., clean soil removed

for development purposes), including transport to a Part 360-16 Registration Facility, a formal

request will be made for approval by OER with an associated plan compliant with 6NYCRR Part

360-16. This request and plan will include the location, volume and a description of the material

to be recycled, including verification that the material is not impacted by site uses and that the

material complies with receipt requirements for recycling under 6NYCRR Part 360. This

material will be appropriately handled on-Site to prevent mixing with impacted material.

1.7 Materials Reuse On-Site

Soil and fill that is derived from the property that meets the Soil Cleanup Objectives (SCOs)

established in this plan may be reused on-Site. The SCOs for on-Site reuse are listed in Section

4.2 of this cleanup plan. ‘Reuse on-Site’ means material that is excavated during the remedy or

development, does not leave the property, and is relocated within the same property and on land

with comparable levels of contaminants in soil/fill material, compliant with applicable laws and

regulations, and addressed pursuant to the NYC VCP agreement subject to Engineering and

Institutional Controls. The PE/QEP will ensure that reused materials are segregated from other

materials to be exported from the Site and that procedures defined for material reuse in this

remedial plan are followed. The expected location for placement of reused material is shown in

Section 4.2.

Organic matter (wood, roots, stumps, etc.) or other waste derived from clearing and grubbing of

the Site will not be buried on-Site. Soil or fill excavated from the site for grading or other

purposes will not be reused within a cover soil layer or within landscaping berms.

1.8 Demarcation

After completion of hotspot removal and any other invasive remedial activities, and prior to

backfilling, the top of the residual soil/fill will be defined by one of three methods: (1) placement

of a demarcation layer. The demarcation layer will consist of geosynthetic fencing or equivalent

5

material to be placed on the surface of residual soil/fill to provide an observable reference layer.

A description or map of the approximate depth of the demarcation layer will be provided in the

SMP; or (2) a land survey of the top elevation of residual soil/fill before the placement of cover

soils, pavement and associated sub-soils, or other materials or structures or, (3) all materials

beneath the approved cover will be considered impacted and subject to site management after the

remedy is complete. Demarcation may be established by one or any combination of these three

methods. As appropriate, a map showing the method of demarcation for the Site and all

associated documentation will be presented in the RAR.

This demarcation will constitute the top of the site management horizon. Materials within this

horizon require adherence to special conditions during future invasive activities as defined in the

Site Management Plan.

1.9 Import of Backfill Soil From Off-Site Sources

This Section presents the requirements for imported fill materials to be used below the cover

layer and within the clean soil cover layer. All imported soils will meet OER-approved backfill

and cover soil quality objectives for this Site. Imported soils will not exceed groundwater

protection standards established in Part 375. Imported soils for Track 1 remedial action projects

will not exceed Track 1 SCO’s.

A process will be established to evaluate sources of backfill and cover soil to be imported to the

Site, and will include an examination of source location, current and historical use(s), and any

applicable documentation. Material from industrial sites, spill sites, environmental remediation

sites or other potentially contaminated sites will not be imported to the Site.

The following potential sources may be used pending attainment of backfill and cover soil

quality objectives:

• Clean soil from construction projects at non-industrial sites in compliance with applicable

laws and regulations;

• Clean soil from roadway or other transportation-related projects in compliance with

applicable laws and regulations;

• Clean recycled concrete aggregate (RCA) from facilities permitted or registered by the

regulations of NYS DEC.

6

All materials received for import to the Site will be approved by a PE/QEP and will be in

compliance with provisions in this remedial plan. The final remedial report will report the

source of the fill, evidence that an inspection was performed on the source, chemical sampling

results, frequency of testing, and a Site map indicating the locations where backfill or soil cover

was placed.

All material will be subject to source screening and chemical testing. Inspection of imported fill

material will include visual, olfactory and PID screening for evidence of contamination.

Materials imported to the Site will be subject to inspection, as follows:

• Trucks with imported fill material will be in compliance with applicable laws and

regulations and will enter the Site at designated locations;

• The PE/QEP is responsible to ensure that every truck load of imported material is

inspected for evidence of contamination; and

• Fill material will be free of solid waste including pavement materials, debris, stumps,

roots, and other organic matter, as well as ashes, oil, perishables or foreign matter.

Composite samples of imported material will be taken at a minimum frequency of one sample

for every 500 cubic yards of material. Once it is determined that the fill material meets imported

backfill or cover soil chemical requirements and is non-hazardous, and lacks petroleum

contamination, the material will be loaded onto trucks for delivery to the Site.

Recycled concrete aggregate (RCA) will be imported from facilities permitted or registered by

NYSDEC. Facilities will be identified in the final remedial report. A PE/QEP is responsible to

ensure that the facility is compliant with 6NYCRR Part 360 registration and permitting

requirements for the period of acquisition of RCA. RCA imported from compliant facilities will

not require additional testing, unless required by NYSDEC under its terms for operation of the

facility. RCA imported to the Site must be derived from recognizable and uncontaminated

concrete. RCA material is not acceptable for, and will not be used as cover material.

1.10 Fluids Management

All liquids to be removed from the Site, including dewatering fluids, will be handled, transported

and disposed in accordance with applicable laws and regulations. Liquids discharged into the

New York City sewer system will receive prior approval by New York City Department of

Environmental Protection (NYC DEP). The NYC DEP regulates discharges to the New York

7

City sewers under Title 15, Rules of the City of New York Chapter 19. Discharge to the New

York City sewer system will require an authorization and sampling data demonstrating that the

groundwater meets the City’s discharge criteria. The dewatering fluid will be pretreated as

necessary to meet the NYC DEP discharge criteria. If discharge to the City sewer system is not

appropriate, the dewatering fluids will be managed by transportation and disposal at an off-Site

treatment facility.

Discharge of water generated during remedial construction to surface waters (i.e., a stream or

river) is prohibited without a SPDES permit issued by the NYSDEC.

1.11 Stormwater Pollution Prevention

Applicable laws and regulations pertaining to stormwater pollution prevention will be addressed

during the remedial program. Erosion and sediment control measures identified in this remedial

plan (silt fences and barriers and hay bale checks) will be installed around the entire perimeter of

the remedial construction area and inspected once a week and after every storm event to ensure

that they are operating appropriately. Discharge locations will be inspected to determine whether

erosion control measures are effective in preventing significant impacts to receptors. Results of

inspections will be recorded in a logbook and maintained at the Site and available for inspection

by OER. All necessary repairs shall be made immediately. Accumulated sediments will be

removed as required to keep the barrier and hay bale check functional. Undercutting or erosion

of the silt fence toe anchor will be repaired immediately with appropriate backfill materials.

Manufacturer's recommendations will be followed for replacing silt fencing damaged due to

weathering.

1.12 Contingency Plan for Unknown Contamination Sources

This contingency plan is developed for the remedial construction to address the discovery of

unknown structures or contaminated media during excavation. Identification of unknown

contamination source areas during invasive Site work will be promptly communicated to OER’s

Project Manager. Petroleum spills will be reported to the NYSDEC Spill Hotline. These findings

will be included in the daily report. If previously unidentified contaminant sources are found

during on-Site remedial excavation or development-related excavation, sampling will be

performed on contaminated source material and surrounding soils and reported to OER.

8

Chemical analytical testing will be performed for TAL metals, TCL volatiles and semi-volatiles,

TCL pesticides and PCBs, as appropriate.

1.13 Odor, Dust, and Nuisance Control

Odor Control

All necessary means will be employed to prevent on- and off-Site odor nuisances. At a

minimum, procedures will include: (a) limiting the area of open excavations; (b) shrouding open

excavations with tarps and other covers; and (c) use of foams to cover exposed odorous soils. If

odors develop and cannot otherwise be controlled, additional means to eliminate odor nuisances

will include: (d) direct load-out of soils to trucks for off-Site disposal; and (e) use of chemical

odorants in spray or misting systems.

This odor control plan is capable of controlling emissions of nuisance odors. If nuisance odors

are identified, work will be halted and the source of odors will be identified and corrected. Work

will not resume until all nuisance odors have been abated. OER will be notified of all odor

complaint events. Implementation of all odor controls, including halt of work, will be the

responsibility of the PE/QEP’s certifying this remedial plan.

Dust Control

Dust management during invasive on-Site work will include, at a minimum:

• Use of a dedicated water spray methodology for roads, excavation areas and stockpiles.

• Use of properly anchored tarps to cover stockpiles.

• Exercise extra care during dry and high-wind periods.

• Use of gravel or RCA on egress and other roadways to provide a clean and dust-free road

surface.

This dust control plan is capable of controlling emissions of dust. If nuisance dust emissions are

identified, work will be halted and the source of dusts will be identified and corrected. Work

will not resume until all nuisance dust emissions have been abated. OER will be notified of all

dust complaint events. Implementation of all dust controls, including halt of work, will be the

responsibility of the PE/QEP’s responsible for certifying this remedial plan.

9

Other Nuisances

Noise control will be exercised during the remedial program. All remedial work will conform, at

a minimum, to NYC noise control standards. Rodent control will be provided during Site

clearing and grubbing and during the remedial program, as necessary, to prevent nuisances.

1.14 Import of Clean Cover Soil

Importation of soil is not anticipated; however, any imported soil will be uncontaminated,

clean soil that meets the lower of the appropriate 6 NYCRR Part 375-6.8(a) Unrestricted Use and

Protection of Groundwater SCOs.

The imported uncontaminated, clean soil cover will be from an approved source/facility and

will be evaluated by the PE or QEP to ensure that the following has been accomplished.

Imported uncontaminated, clean soil cover will conform to the following, as evaluated by

individuals reporting to the PE or QEP:

1. A segregated stockpile will be properly maintained at the source and will not be

comingled with any other material prior to importing and grading the clean soil material

at the Site;

2. The material will not include any solid waste, including construction and demolition

material, as it is prohibited;

3. Screening for evidence of contamination by visual, olfactory and PID screening practices

will occur prior to testing at the source as well as upon importing to the Site for grading is

completed; and

4. A maximum five-part composite sample will be collected from the segregated stockpile

at the source at a frequency in accordance with CP-51 Soil Cleanup Guidance Table 4 or

at a frequency negotiated with the OER, depending on the proposed source material and

analyzed for the following parameters:

VOCs by EPA Method 8260C

SVOCs by EPA Method 8270D

Pesticides by EPA Method 8081B

PCBs by EPA Method 8082A

TAL Metals by EPA Method 6010C/7471B

10

Upon receipt of the segregated stockpile analytical results collected at the source, a Clean

Soil Sampling Report will be submitted to the OER for review/approval prior to importing. The

report will include the following:

1. Summary of number of samples collected and analyzed, tabulated data and comparison to

Track 1 SCOs;

2. Analytical data sheets and chain of custody documentation;

3. Photographs from the segregated stockpile at the source with sample point locations

identified;

4. An affidavit from the source/facility on company letterhead stating that the segregated

stockpile for about 150 tons (100 cubic yards) has been properly maintained at the source

and complies with the requirements listed above; and

5. A copy of source/facility permit;

Demarcation as previously described will be complete prior to installation of the clean soil

or fill surface cover. Upon importing and grading the OER-approved clean soil cover, the

following documentation will be presented in the RAR:

1. Copies of purchase invoices;

2. Truck transportation slips from the source to the Site;

3. Confirmation of the volume of the OER-approved clean soil cover material imported and

graded at the Site;

4. A site plan depicting all areas where the OER-approved clean soil cover was placed;

5. Documentation of demarcation method; and

6. Photographs documenting the importing and grading of the OER-approved clean soil

cover across the Site, and where applicable, the demarcation layer.

InstallationThe most current application instructions, detail drawings and technical letters can be viewed at graceconstruction.com. For other technical information contact your local Grace representative.Preprufe® 300R & 160R membranes are supplied in rolls 4 ft (1.2 m) wide, with a selvedge on one side to provide self-adhered laps for continuity between rolls. The rolls of Preprufe Membrane and Preprufe Tape are interwound with a disposable plastic release liner which must be removed before placing reinforcement and concrete.Substrate PreparationAll surfaces—It is essential to create a sound and solid substrate to eliminate movement during the concrete pour. Substrates must be regular and smooth with no gaps or voids greater than 0.5 in. (12 mm). Grout around all penetrations such as utility conduits, etc. for stability (see Figure 1).Horizontal—The substrate must be free of loose aggregate and sharp protrusions. Avoid curved or rounded substrates. When installing over earth or crushed stone, ensure substrate is well compacted to avoid displacement of substrate due to traffic or concrete pour. The surface does not need to be dry, but standing water must be removed.Vertical—Use concrete, plywood, insulation or other approved facing to sheet piling to provide support to the membrane. Board systems such as timber lagging must be close butted to provide support and not more than 0.5 in. (12 mm) out of alignment.Membrane InstallationPreprufe® membranes can be applied at temperatures of 25°F (-4°C) or above. When installing Preprufe product in cold or marginal weather conditions 55°F (<13°C) the use of Preprufe Tape LT is recommended at all laps and detailing. Preprufe Tape LT should be applied to clean, dry surfaces and the release liner must be removed immediately after application. Alternatively, Preprufe Low Temperature (LT) membrane is available for low temperature condition applications. Refer to Preprufe LT data sheet and Grace Tech Letter 16 for more information.Horizontal substrates—Place the membrane HDPE film side to the substrate with the clear plastic release liner facing towards the concrete pour. End laps should be staggered to avoid a build up of layers. Leave plastic release liner in position until overlap procedure is completed (see Figure 2). Accurately position succeeding sheets to overlap the previous sheet 3 in. (75 mm) along the marked selvedge. Ensure the underside of the succeeding sheet is clean, dry and free from contamination before attempting to overlap. Peel back the plastic release liner from between the overlaps as the two layers are bonded together. Ensure a continuous bond is achieved without creases and roll firmly with a heavy roller. Completely remove the plastic liner to expose the protective coating. Any initial tack will quickly disappear products.Refer to Grace Tech Letter 15 for information on suitable rebar chairs for Preprufe products.Vertical substrates—Mechanically fasten the membrane vertically using fasteners appropriate to the substrate with the the clear plastic release liner facing towards the concrete pour. The membrane may be installed in any convenient length. Fastening can be

made through the selvedge using a small and low profile head fastener so that the membrane lays flat and allows firmly rolled overlaps. Immediately remove the plastic release liner. Ensure the underside of the succeeding sheet is clean, dry and free from contamination before attempting to overlap. Roll firmly to ensure a watertight seal. Roll ends and cut edges—Overlap all roll ends and cut edges by a minimum 3 in. (75 mm) and ensure the area is clean and free from contamination, wiping with a damp cloth if necessary. Allow to dry and apply Preprufe® Tape LT (or HC in hot climates) centered over the lap edges and roll firmly (see Figure 3). Immediately remove printed plastic release liner from the tape.DetailsDetail drawings are available at graceconstruction.com.Membrane RepairInspect the membrane before installation of reinforcement steel, formwork and final placement of concrete. The membrane can be easily cleaned by power washing if required. Repair damage by wiping the area with a damp cloth to ensure the area is clean and free from dust, and allow to dry. Repair small punctures (0.5 in. (12 mm) or less) and slices by applying Preprufe® Tape centered over the damaged area. Repair holes and large punctures by applying a patch of Preprufe membrane, which extends 6 in. (150 mm) beyond the damaged area. Seal all edges of the patch with Preprufe Tape. Any areas of damaged adhesive should be covered with Preprufe Tape. Where exposed selvedge has lost adhesion or laps have not been sealed, ensure the area is clean and dry and cover with fresh Preprufe Tape. All Preprufe Tape must be rolled firmly and the tinted release liner removed. Alternatively, use a hot air gun or similar to activate the adhesive using caution not to damage the membrane and firmly roll lap to achieve continuity.Pouring of ConcreteEnsure the plastic release liner is removed from all areas of Preprufe membrane and tape.It is recommended that concrete be poured within 56 days (42 days in hot climates) of application of the membrane. Following proper ACI guidelines, concrete must be placed carefully and consolidated properly to avoid damage to the membrane. Never use a sharp object to consolidate the concrete.Removal of FormworkPreprufe® membranes can be applied to removable formwork, such as slab perimeters, elevator and lift pits, etc. Once the concrete is poured the formwork must remain in place until the concrete has gained sufficient compressive strength to develop the surface bond. Preprufe membranes are not recommended for conventional twin-sided wall forming systems, see Grace Tech Letter 13 for information on forming systems used with Preprufe products.

SAFETY

Bituthene products must be properly handled.Vapors from the solvent based primer andmastic are harmful and flammable. For theseproducts, the best available information onsafe handling, storage, personal protection,health and environmental considerations hasbeen gathered and is available on MaterialSafety Data Sheets (MSDS). All users shouldacquaint themselves with this information.

Carefully read detailed precaution statementson product labels and MSDS before use, orcontact Grace Construction Products.

STORAGE & HANDLING

Protect all materials from rain and physicaldamage. Do not double stack pallets ofmembrane on the jobsite. Provide tarpaulincover on top and all sides, allowing for ade-quate ventilation. Store membrane wheretemperatures will not exceed 90 degrees F (32 degrees C) for extended periods. In lowtemperature conditions, the membraneshould be stored above 40 degrees F (5 degrees C) to promote good adhesion.Store all products in a dry area away fromhigh heat, flames or sparks. Store only asmuch material at point-of-use as required foreach day’s work.

PREPARATORY WORK

Surface ConditionConcrete must be smooth, monolithic andfree of voids, spalled areas, loose substrateand sharp protrusions, dirt and debris, andmust contain no visible coarse aggregate.Repair defects such as spalled or poorly con-solidated areas. Use Bituthene Deck PrepSurface Treatment to smooth and level roughconcrete decks. Remove sharp protrusionsand form match lines.

CuringConcrete must be cured a minimum of 7 daysfor normal structural concrete and 14 days forlightweight structural concrete. If concrete isplaced over a nonvented metal deck, therequired curing time is doubled. Use formrelease agents that will not transfer to the con-crete. Remove forms as soon as possible frombelow horizontal slabs to prevent entrapmentof excess moisture. Excess moisture can lead toblistering of the membrane. Cure concretewith clear, resin based curing compounds con-taining no oil, wax or pigment. Allow concreteto thoroughly dry following rain.

On masonry surfaces, apply a parge coatto rough concrete block and brick walls ortrowel-cut mortar joints flush to the face ofthe concrete blocks.

Cure time and drying time for concreteand masonry surfaces may be reduced byusing Bituthene Primer B2.

APPLICATION

Surface ConditionerBituthene System 4000 Surface Conditioner issupplied ready to use. Do not dilute with wateror solvents. Spray surface conditioner uniformlyto substrate at a rate of 300 ft2/gal (7.5 m2/L).Use appropriate sprayer and nozzle.

Allow surface conditioner to dry completelyand thoroughly prior to membrane application.The surface conditioner is considered dry whenthe substrate returns to its original color. To testfor dryness, rub small conditioned area by

hand. Wet conditioner will ball up under the fin-gertips. Let dry until conditioner cannot berubbed off. If conditioned areas are not covered that day, recondition the area if thereis significant dust or dirt contamination.

PrimerApply Bituthene Primer WP-3000 by spray orroller at a coverage rate of 500 - 600 ft2/gal(12 - 15 m2/L). Allow to dry 1 hour or until con-crete returns to original color.

Apply Bituthene Primer B2 by lamb’s woolroller at a coverage rate of 250 - 350 ft2/gal (6- 8 m2/L). Allow primer to dry 1 hour or until tack-free. Dry time may be longer in cold tempera-tures.

Reprime areas if contaminated by dust. Ifthe work area is dusty, apply membrane assoon as the primer is dry.

Surfaces treated with Deck Prep SurfaceTreatment do not require conditioning or prim-ing. Metal does not require priming but mustbe clean, dry and free of loose paint, rust orother contaminants. Use Bituthene Primer B2 fordamp or green substrates. Do not applyprimer or surface conditioner to membrane.

CornersThe treatment of corners varies depending onthe location of the corner.

At wall-to-footing inside corners:• Option 1 - Apply membrane to within 1"

(25 mm) of base of wall. Treat the insidecorner by installing a 3/4" (19 mm) fillet of Bituthene Liquid Membrane. Extend liquidmembrane at least 3" (75 mm) onto wallmembrane

• Option 2 - Treat the inside corner by installing a 3/4" (19 mm) fillet of BitutheneLiquid Membrane.

For outside corners, apply 12" (300 mm)membrane strip centered on corner. Coverthe treated corner with a full sheet of mem-brane to ensure 2-ply coverage.

JointsProperly seal all joints with waterstop, joint fillerand sealant as required. Bituthene mem-branes are not intended to function as theprimary joint seal. Allow sealant to fully cure.Prestrip all slabs and wall cracks over 1/16" (1.6 mm) wide and all construction and controljoints with 9" (225 mm) wide membrane.

DrainsAt drains, apply a collar of membrane whichextends 6" (150 mm) beyond the drain open-ing. Apply full coverage of membrane overthe collar. Cut out the drain opening so themembrane extends under the clamping ring.Place a bead of Bituthene Mastic or BitutheneLiquid Membrane between the membraneand clamping ring. An alternate method is toapply Bituthene Liquid Membrane 0.090" (2.3mm) thick so that it extends under the clamp-ing ring and overlaps the deck membrane atleast 3" (75 mm). Install clamping ring afterBituthene Liquid Membrane has cured.

Application to Horizontal SurfacesApply membrane from the low point to thehigh point so that laps shed water. Overlap all

seams at least 2 1/2" (64 mm). Stagger all endlaps.

Roll the entire membrane firmly and com-pletely as soon as possible. Use a linoleumroller or standard water-filled garden rollerless than 30" (762 mm) wide, weighing a mini-mum of 75 lb (34 kg) when filled. Cover theface of the roller with a resilient material suchas a 1/2" (13 mm) plastic foam or 2 wraps ofindoor/outdoor carpet to allow the mem-brane to fully contact the primed substrate.

Seal all T-joints and membrane terminationswith Bituthene Mastic or Bituthene LiquidMembrane at the end of the day.

For required testing of horizontal applica-tions, see Flood Testing.

Application to Vertical SurfacesApply membrane in lengths up to 8' (2 m).Overlap all seams 2 1/2" (64 mm) minimum. On higher walls, apply membrane in 2 or moresections with the upper overlapping the lowerby at least 2 1/2" (64 mm). Roll membrane witha hand roller.

Terminate the membrane at grade level.Press the membrane firmly to the wall with thebutt end of a hardwood tool such as ahammer handle, or secure into a reglet. A ter-mination bar may be used to secure the toptermination. Failure to use heavy pressure atterminations can result in a poor seal.

Terminate the membrane at the base ofthe wall if the bottom of the interior floor slabis at least 6" (150 mm) above the

Apply atroweled bead of Bituthene Mastic orBituthene Liquid Membrane to all vertical andhorizontal terminations at the end of eachworkday.

Protrusions and PenetrationsApply membrane to within 1" (25 mm) of thebase of the protrusion. Apply Liquid Membrane0.090" (2.3 mm) thick around the protrusion.Extend Bituthene Liquid Membrane over thesheet membrane at least 3" (75 mm) and upthe protrusion to just below the finished heightof the wearing course (for horizontal applica-tions) or for a minimum of 6" (150 mm) for ver-tical applications.

FLOOD TESTING

Flood test all horizontal applications with aminimum 2" (50 mm) head of water for 24hours. Mark any leaks and repair when themembrane is dry. Before flood testing, be surethe structure will withstand the dead load of the water. For well-sloped decks, segment theflood test to avoid deep water near drains.

Conduct the flood test 1 day after com-pleting the application of Bituthene water-proofing system. Immediately after flood testis completed, and all necessary repairs made,install Hydroduct 660 Drainage Composite toprotect the Bituthene membrane from trafficand other trades.

MEMBRANE REPAIR

Patch tears and inadequately lapped seamswith membrane. Slit fishmouths and repair witha patch extending 6" (150 mm) in all directionsfrom the slit and seal edges of the patch withBituthene Mastic. Inspect the membrane thor-oughly before covering and make any repairs.

PROTECTION

Protection of MembraneProtect Bituthene membranes to avoid dam-age from other trades’ construction materialsor backfill. Place protection immediately in tem-peratures above 77 degrees F (25 degrees C) toreduce potential for blistering.

On horizontal applications, use Hydroduct660 Drainage Composite for protection.Adhere as necessary to membrane withHydroduct Tape.

Alternate methods are to use 1/8" or 1/4" (3 or 6 mm) asphaltic hardboard. When rein-forced concrete slabs are placed over the

membrane, use Hydroduct 660 DrainageComposite or 1/4" (6 mm) hardboard or 2 lay-ers of 1/8" (3 mm) hardboard.

On vertical applications, use Hydroduct 220Drainage Composite. Adhere Hydroduct 220 tomembrane with Hydroduct Tape. Alternative protection methods are to use 1" (25 mm)expanded polystyrene or 1/4" (6 mm) extruded polystyrene that has a minimumcompressive strength of 10 lb/in2 (69 kN/m2).

If 1/4" (6 mm) extruded polystyrene protec-tion board is used, backfill should not containsharp rock or aggregate over 2" (50 mm) indiameter. Adhere polystyrene protectionboard with Hydroduct Tape or compatibleadhesive.

Cover any exposed Bituthene membranewith weather resistant flashing such as cop-per, aluminum or neoprene. Install Hydroduct660 Drainage Composite or alternate protec-tion the same day the membrane is appliedor immediately after a 24 hour flood test. Nowaiting before backfill or application of wear-ing course is necessary.

Placement of BackfillUse care during backfill operation to avoiddamage to waterproofing and drainage sys-tem. Follow generally accepted practice forbackfill and compaction. Backfill should beadded in 6" - 12" (150 - 300 mm) lifts. Forbermed areas that cannot be fully com-pacted, a termination bar is recommendedacross the top termination of the membrane.

In general, backfill or the final wearingcourse should be placed as soon as possibleafter installation of the membrane.

Placement of Reinforcing SteelWhen placing reinforcing steel over properlyprotected membrane, use concrete bar sup-ports (dobies) or chairs with plastic tips orrolled feet to prevent damage from sharpedges. Use special care when using wiremesh, especially if the mesh is curled.

1.0 INTRODUCTION

1.1 General

This CONSTRUCTION HEALTH AND SAFETY PLAN (CHASP) was developed to address

disturbance of known and reasonably anticipated subsurface contaminants and comply with

Occupational Safety and Health Administration (OSHA) Standard 29 CFR 1910.120(b) (4),

Hazardous Waste Operations and Emergency Response during anticipated remedial activities

to be conducted at 181 Mercer Street, New York, New York (Tax Block 524, Lot 66) (“the Site).

This CHASP provides the minimum requirements for implementing site operations during

remedial activities. All contractors performing work on this Site shall implement their own

CONSTRUCTION HEALTH AND SAFETY PLANs that, at a minimum, adhere to this CHASP.

The contractor is solely responsible for their own health and safety and that of their

subcontractors. Langan personnel will implement this CHASP while on-site.

The management of the day-to-day site activities and implementation of this CHASP in the field

is the responsibility of the site Langan Field Team Leader (FTL). Assistance in the

implementation of this CHASP can also be obtained from the site Langan Health and Safety

Officer (HSO) and the Langan Health and Safety Manager (HSM). Contractors operating on the

Site shall designate their own FTL, HSO and HSM. The content of this CHASP may change or

undergo revision based upon additional information made available to health and safety

personnel, monitoring results, or changes in the work plan.

1.2 Site Location and Background

The Site is located in the Greenwich Village neighborhood of Manhattan, and occupies the

eastern portion of Block 524, Lot 66 on the NYC Tax Map. The Site occupies a footprint of

about 80,700 square feet. The Site is improved with a one-story building previously occupied

by the NYU Coles Sports Recreation Center, which is located on the city block bound by West

Houston Street to the south, Mercer Street to the east, Bleecker Street to the north and

LaGuardia Place to the west. The building occupies a majority of the Site and includes one sub-

mezzanine and one basement level. The recreation center was vacated in January 2016, and

interior demolition work inside the building had begun by the time Langan commenced field

work for the RI on February 23, 2016. The building contains former weight and aerobics rooms,

squash and racquetball courts, dance studios, locker rooms, and two swimming pools. A

former dog park, sitting area and playground occupy the exterior eastern portion of the Site

along Mercer Street. A landscaped area occupies the western exterior portion of the property

adjacent to the former Greene Street Walkway. A Con Edison easement runs along the Greene

Street walkway. The Site elevation at basement grade is about el. 7.5 NAVD 88. The elevation

at sidewalk grade ranges from about el. 34 to el. 36. A site location map is provided as Figure

1.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 2

New York, New York

Langan Project No. 170001401

Historical maps indicate that the Site was located in a densely developed area and improved

with five- and six-story commercial and residential buildings with basements between 1894 and

1950. Buildings containing a woodwork facility, wool clipping sorting facility, and food products

company were located on the Site in 1950. The buildings were demolished by 1966. Greene

Street was demapped and NYU developed the western adjoining parcel in the late 1960s. The

Site remained a vacant lot until construction of the existing building in approximately 1980. A

March 1981 certificate of occupancy identifies the building as a recreational center.

1.3 Summary of Work Tasks

The general categories of work tasks being performed during implementation of the work plan

include:

1.3.1 Excavation and Soil Screening

Langan personnel will screen excavated material for visual, olfactory, and instrumental

indicators suggestive of a potential chemical or petroleum release. Instrument screening for

the presence of volatile organic compounds (VOCs) may be performed with a calibrated

photoionization detector (PID). Contractors will excavate for utilities, foundation components

and potential grading using heavy equipment and hand tools. Contractors will notify Langan

personnel if they identify indications suggestive of a potential chemical or petroleum release.

Contaminated material shall be handled and property disposed in accordance with federal, state

and city regulations, criteria and guidelines.

1.3.2 Stockpiling

Potentially impacted soil may be stockpiled on-site prior to off-site disposal at a facility

permitted to accept the material. Visibly contaminated soil, if encountered, shall be segregated

and stockpiled on at least 10 millimeters of plastic sheeting; reusable soil and fill shall be

segregated and stockpiled separately from unusable fill, concrete and other debris; the

stockpiles shall be kept covered with 6 millimeters thick plastic sheeting; the plastic sheeting

covering the stockpiles shall be anchored firmly in place by weights, stakes, or both; the

Contractor shall maintain the plastic sheeting. If stockpile soil sampling is required from above

ground level, suitable excavation equipment (i.e., excavator, front end loader) should be used to

collect the sample. In the event of discrepancies between the requirements specified herein

and those specified in the Soil/Materials Management Plan (SMMP) in Appendix 5 of the

Remedial Action Work Plan (RAWP), the more stringent requirements will apply.

1.3.3 Soil Sampling

Soil samples (waste characterization, excavation endpoint, delineation, or quality

assurance/quality control [QA/QC]) may be collected during construction, as required. Samples

Construction Health & Safety Plan November 2016

181 Mercer Street Page 3

New York, New York

Langan Project No. 170001401

will be placed into laboratory-supplied batch-certified clean glassware and submitted to a New

York State Department of Health (NYSDOH) Environmental Laboratory Accreditation Program

(ELAP)-certified laboratory.

1.3.4 Removal of Underground Storage Tank

If encountered, the contractor shall furnish all labor and materials, equipment and incidentals

required for the proper decontamination, removal and closure of any UST in accordance with

federal, state and local regulations. Langan personnel will monitor VOCs with a calibrated PID

downwind from the UST excavation and record the PID readings.

1.3.5 Drum Sampling

Excess or impacted soil or fluid may be drummed separately in approved 55-gallon sealed

drums, as required. Each drum must be labeled in accordance with the Langan Drum Labeling

Standard Operating Procedure (SOP-#9). Langan field personnel will collect drum samples, as

required, during construction prior to off-site drum disposal. Samples will be placed into

laboratory-supplied batch-certified clean glassware and submitted to a NYSDOH ELAP-certified

laboratory.

1.3.6 Support of Excavation (SOE)

Langan personnel will perform observational and inspection activities in support of excavation.

These activities include drilling of soil pilings and tiebacks and other activities specified in the

work plan.

1.3.7 Dewatering Treatment System

The contractor shall be responsible for sampling, treatment and disposal of all contaminated

groundwater removed from the site in accordance with federal, state and local regulations. The

contractor shall provide sufficient containerized storage to allow for testing of groundwater prior

to and after treatment and before disposal. If required, Langan field personnel may sample

dewatering treatment system liquids from either a discharge standpipe or a storage tank.

Dewatering samples will be submitted to an ELAP-certified laboratory for analysis.

1.3.8 Installation of Waterproofing and Vapor Barrier

A properly licensed contractor will install the waterproofing membrane and vapor barrier system

in accordance with specifications outlined in the work plan. Langan or other authorized

personnel, as specified in the contract documents, will inspect the waterproofing and vapor

barrier installation and in accordance with the specification outlined in the work plan.

3.0 TASK/OPERATION SAFETY AND HEALTH RISK ANALYSES

A Task-Hazard Analysis (Table 1) was completed for general construction hazards that may be

encountered at the Site. Known and suspected chemical contaminant hazards that could be

encountered during site operations are included in Table 2. A complete inventory of

MSDS/SDS for chemical products used on site is included as Attachment E.

3.1 Specific Task Safety Analysis

3.1.2 Excavation and Soil Screen

Soil handling or screening activities requires the donning of chemical resistant gloves in addition

to the standard PPE. Langan personnel are not to operate drilling or excavation equipment nor

open sampling devices (acetate liners, sonic sample bags, etc.). These tasks are to be

completed by the contractor.

3.1.2 Stockpiling

If stockpiling is required, potentially impacted soil shall be segregated and stockpiled on at least

10 millimeters of plastic sheeting; reusable soil and fill shall be segregated and stockpiled

separately from unusable fill, concrete and other debris; the stockpiles shall be kept covered

with a minimum 6 millimeter thick plastic sheeting; the plastic sheeting covering the stockpiles

shall be anchored firmly in place by weights, stakes, or both; the Contractor shall maintain the

plastic sheeting. If stockpile soil sampling is required from above ground level, suitable

excavation equipment (i.e., excavator, front end loader) should be used to collect the sample.

3.1.3 Soil Sampling

Sampling soil requires the donning of chemical resistant gloves in addition to the standard PPE.

3.1.4 Removal of Underground Storage Tank

If UST excavation and removal activity is initiated, Langan personnel will conduct air monitoring

for lower explosion limit (LEL) conditions within the UST excavation itself. This task is to be

performed using calibrated air monitoring equipment designed to sound an audio alarm when

Construction Health & Safety Plan November 2016

181 Mercer Street Page 7

New York, New York

Langan Project No. 170001401

atmospheric concentrations of VOC are within 10% of the LEL. In normal atmospheric oxygen

concentrations, the LEL monitoring may be done with a Wheatstone bridge/catalytic bead type

sensor (i.e. MultiRAE). However in oxygen depleted atmospheres (confined space), only an

LEL designed to work in low oxygen environments may be used. Best practices require that

the LEL monitoring unit be equipped with a long sniffer tube to allow the LEL unit to remain

outside the UST excavation. Langan personnel are not to enter the UST excavation nor enter

an excavated UST.

In addition to monitoring LEL, Langan personnel will monitor atmospheric VOC concentrations

directly downwind of the UST excavation in accordance with standard CAMP procedures using

calibrated air monitoring equipment.

3.1.5 Drum Sampling

Sampling drums requires the donning of work gloves when opening the drums and chemical

resistant gloves when sampling in addition to standard PPE.

Langan personnel and contractors are not to move or opened any orphaned (unlabeled) drum

found on the site without approval of the project manager.

3.2.6 Support of Excavation

The contractor will operate drilling equipment used to install the soil pilings and tiebacks.

Langan personnel will inspect in accordance with specification in the work plan and record the

data the work plan and/or contract documents require. The installation of the soil pilings and

tiebacks are to be done exclusively by the contractor following their own health and safety

specifications outlined in their CHASPs. Other activities assigned to Langan as part of the SOE

are limited to inspection and observations as specified in the work plan and/or contract

documents. Langan personnel are not to operate or assist in the operation of equipment used

in the SOE unless defined as part of an inspection or observation in the work plan and/or

contract documents.

3.1.7 Dewatering Treatment System

When required by the work plan to sample water treatment discharge effluent, the Langan field

staffer will don additional PPE including nitrile gloves and if necessary, facial and body splash

protection. Samples should be collected from a ground level discharge point. A sample

discharge point that is at an elevation above six feet must be accessible from a platform that

meets OSHA fall protection standards (i.e. guardrail and toe rail). When fall protection is

inadequate, Langan personnel must be don fall protection and be certified in its proper use.

3.1.8 Installation of Waterproofing and Vapor Barrier System

Specifically trained contractors are to install the waterproofing membrane and vapor barrier

Construction Health & Safety Plan November 2016

181 Mercer Street Page 8

New York, New York

Langan Project No. 170001401

system. Langan personnel will inspect in accordance with specification in the work plan and

record the data the work plan requires. Installation and assemblage of the waterproofing

membrane and vapor barrier system are to be done exclusively by the contractor following their

own health and safety specifications outlined in their CHASPs.

3.2 Radiation Hazards

No radiation hazards are known or expected at the site.

3.3 Physical Hazards

Physical hazards, which may be encountered during site operations for this project, are detailed

in Table 1.

3.3.1 Explosion

No explosion hazards are expected for the scope of work at this site.

3.3.2 Heat Stress

The use of Level C protective equipment, or greater, may create heat stress. Monitoring of

personnel wearing personal protective clothing should commence when the ambient

temperature is 72oF or above. Table 6 presents the suggested frequency for such monitoring.

Monitoring frequency should increase as ambient temperature increases or as slow recovery

rates are observed. Refer to the Table 7 to assist in assessing when the risk for heat related

illness is likely. To use this table, the ambient temperature and relative humidity must be

obtained (a regional weather report should suffice). Heat stress monitoring should be

performed by the HSO or the FTL, who shall be able to recognize symptoms related to heat

stress.

To monitor the workers, be familiar with the following heat-related disorders and their

symptoms:

Heat Cramps: Painful spasm of arm, leg or abdominal muscles, during or after work

Heat Exhaustion: Headache, nausea, dizziness; cool, clammy, moist skin; heavy

sweating; weak, fast pulse; shallow respiration, normal temperature

Heat Stroke: Headache, nausea, weakness, hot dry skin, fever, rapid strong pulse,

rapid deep respirations, loss of consciousness, convulsions, coma. This is a life

threatening condition.

Do not permit a worker to wear a semi-permeable or impermeable garment when they are

showing signs or symptoms of heat-related illness.

To monitor the worker, measure:

Construction Health & Safety Plan November 2016

181 Mercer Street Page 9

New York, New York

Langan Project No. 170001401

Heart rate: Count the radial pulse during a 30-second period as early as possible in the

rest period. If the heart rate exceeds 100 beats per minute at the beginning of the rest

period, shorten the next work cycle by one-third and keep the rest period the same. If

the heart rate still exceeds 100 beats per minute at the next rest period, shorten the

following work cycle by one-third. A worker cannot return to work after a rest period

until their heart rate is below 100 beats per minute.

Oral temperature: Use a clinical thermometer (3 minutes under the tongue) or similar

device to measure the oral temperature at the end of the work period (before drinking).

If oral temperature exceeds 99.6oF (37.6oC), shorten the next work cycle by one-third

without changing the rest period. A worker cannot return to work after a rest period

until their oral temperature is below 99.6oF. If oral temperature still exceeds 99.6oF

(37.6oC) at the beginning of the next rest period, shorten the following cycle by one-

third. Do not permit a worker to wear a semi-permeable or impermeable garment when

oral temperature exceeds 100.6oF (38.1oC).

Prevention of Heat Stress - Proper training and preventative measures will aid in averting loss

of worker productivity and serious illness. Heat stress prevention is particularly important

because once a person suffers from heat stroke or heat exhaustion, that person may be

predisposed to additional heat related illness. To avoid heat stress the following steps should

be taken:

Adjust work schedules.

Mandate work slowdowns as needed.

Perform work during cooler hours of the day if possible or at night if adequate lighting

can be provided.

Provide shelter (air-conditioned, if possible) or shaded areas to protect personnel during

rest periods.

Maintain worker's body fluids at normal levels. This is necessary to ensure that the

cardiovascular system functions adequately. Daily fluid intake must approximately equal

the amount of water lost in sweat, id., eight fluid ounces (0.23 liters) of water must be

ingested for approximately every eight ounces (0.23 kg) of weight lost. The normal

thirst mechanism is not sensitive enough to ensure that enough water will be drunk to

replace lost sweat. When heavy sweating occurs, encourage the worker to drink more.

The following strategies may be useful:

o Maintain water temperature 50o to 60oF (10o to 16.6oC).

o Provide small disposal cups that hold about four ounces (0.1 liter).

o Have workers drink 16 ounces (0.5 liters) of fluid (preferably water or dilute

drinks) before beginning work.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 10

New York, New York

Langan Project No. 170001401

o Urge workers to drink a cup or two every 15 to 20 minutes, or at each

monitoring break. A total of 1 to 1.6 gallons (4 to 6 liters) of fluid per day are

recommended, but more may be necessary to maintain body weight.

o Train workers to recognize the symptoms of heat related illness.

3.3.3 Cold-Related Illness

If work on this project begins in the winter months, thermal injury due to cold exposure can

become a problem for field personnel. Systemic cold exposure is referred to as hypothermia.

Local cold exposure is generally called frostbite.

Hypothermia - Hypothermia is defined as a decrease in the patient core temperature

below 96oF. The body temperature is normally maintained by a combination of central

(brain and spinal cord) and peripheral (skin and muscle) activity. Interference with any of

these mechanisms can result in hypothermia, even in the absence of what normally is

considered a "cold" ambient temperature. Symptoms of hypothermia include: shivering,

apathy, listlessness, sleepiness, and unconsciousness.

Frostbite - Frostbite is both a general and medical term given to areas of local cold

injury. Unlike systemic hypothermia, frostbite rarely occurs unless the ambient

temperatures are less than freezing and usually less than 20oF. Symptoms of frostbite

are: a sudden blanching or whitening of the skin; the skin has a waxy or white

appearance and is firm to the touch; tissues are cold, pale, and solid.

Prevention of Cold-Related Illness - To prevent cold-related illness:

Educate workers to recognize the symptoms of frostbite and hypothermia

Identify and limit known risk factors:

Assure the availability of enclosed, heated environment on or adjacent to the site.

Assure the availability of dry changes of clothing.

Assure the availability of warm drinks.

Start (oral) temperature recording at the job site:

At the FSO or Field Team Leader's discretion when suspicion is based on changes in a

worker's performance or mental status.

At a worker's request.

As a screening measure, two times per shift, under unusually hazardous conditions

(e.g., wind-chill less than 20oF, or wind-chill less than 30oF with precipitation).

As a screening measure whenever anyone worker on the site develops hypothermia.

Any person developing moderate hypothermia (a core temperature of 92oF) cannot return to

work for 48 hours.

3.3.4 Noise

Construction Health & Safety Plan November 2016

181 Mercer Street Page 11

New York, New York

Langan Project No. 170001401

Work activities during the proposed activities may be conducted at locations with high noise

levels from the operation of equipment. Hearing protection will be used as necessary.

3.3.5 Hand and Power Tools

The use of hand and power tools can present a variety of hazards, including physical harm from

being struck by flying objects, being cut or struck by the tool, fire, and electrocution. All hand

and power tools should be inspected for health and safety hazards prior to use. If deemed

unserviceable/un-operable, notify supervisor and tag equipment out of service. Ground Fault

Circuit Interrupters (GFCIs) are required for all power tools requiring direct electrical service.

3.3.6 Slips, Trips and Fall Hazards

Care should be exercised when walking at the site, especially when carrying equipment. The

presence of surface debris, uneven surfaces, pits, facility equipment, and soil piles contribute

to tripping hazards and fall hazards. To the extent possible, all hazards should be identified and

marked on the Site, with hazards communicated to all workers in the area.

3.3.7 Utilities (Electrocution and Fire Hazards)

The possibility of encountering underground utilities poses fire, explosion, and electrocution

hazards. All excavation work will be preceded by review of available utility drawings and by

notification of the subsurface work to the N.Y. One –Call--Center. Potential adverse effects of

electrical hazards include burns and electrocution, which could result in death.

3.4 Biological Hazards

3.4.1 Animals

No animals are expected to be encountered during site operations.

3.4.2 Insects

Insects are not expected to be encountered during site operations.

3.5 Additional Safety Analysis

3.5.1 Presence of Non-Aqueous Phase Liquids (NAPL)

There is potential for exposure to NAPL at this site. Special care and PPE should be considered

when NAPL is observed as NAPL is a typically flammable fluid and releases VOCs known to be

toxic and/or carcinogenic. If NAPL is present in a monitoring well, vapors from the well casing

may contaminate the work area breathing zone with concentrations of VOCs potentially

exceeding health and safety action levels. In addition, all equipment used to monitor or sample

NAPL (or groundwater from wells containing NAPL) must be intrinsically safe. Equipment that

Construction Health & Safety Plan November 2016

181 Mercer Street Page 12

New York, New York

Langan Project No. 170001401

directly contacts NAPL must also be resistant to organic solvents.

At a minimum, a PID should be used to monitor for VOCs when NAPL is observed. If NAPL is

expected to be observed in an excavation or enclosed area, air monitoring must be started

using calibrated air monitoring equipment designed to sound an audio alarm when atmospheric

concentrations of VOC are within 10% of the LEL. In normal atmospheric oxygen

concentrations, the LEL monitoring may be done with a Wheatstone bridge/catalytic bead type

sensor (i.e. MultiRAE). However in oxygen depleted atmospheres (confined space), only an

LEL designed to work in low oxygen environments may be used. Best practices require that

the LEL monitoring unit be equipped with a long sniffer tube to allow the LEL unit to remain

outside the UST excavation.

When NAPL is present, Langan personnel are required to use disposable nitrile gloves at all

times to prevent skin contact with contaminated materials. They should also consider having

available a respirator and protective clothing (Tyvek® overalls), especially if NAPL is in

abundance and there are high concentrations of VOCs.

All contaminated disposables including PPE and sampling equipment must be properly

disposed of in labeled 55-gallon drums.

3.6 Job Safety Analysis

A Job Safety Analysis (JSA) is a process to identify existing and potential hazards associated

with each job or task so these hazards can be eliminated, controlled or minimized. A JSA will

be performed at the beginning of each work day, and additionally whenever an employee

begins a new task or moves to a new location. All JSAs must be developed and reviewed by

all parties involved. A blank JSA form and documentation of completed JSAs are in Attachment

G.

4.0 PERSONNEL TRAINING

4.1 Basic Training

Completion of an initial 40-hour HAZWOPER training program as detailed in OSHA's 29 CFR

1910.120(e) is required for all employees working on a site engaged in hazardous substance

removal or other activities which expose or potentially expose workers to hazardous

substances, health hazards, or safety hazards as defined by 29 CFR 1910.120(a). Annual 8-hour

refresher training is also required to maintain competencies to ensure a safe work environment.

In addition to these training requirements, all employees must complete the OSHA 10 hour

Construction Safety and Health training and supervisory personnel must also receive eight

additional hours of specialized management training. Training records are maintained by the

HSM.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 13

New York, New York

Langan Project No. 170001401

4.2 Initial Site-Specific Training

Training will be provided to specifically address the activities, procedures, monitoring, and

equipment for site operations at the beginning of each field mobilization and the beginning of

each discrete phase of work. The training will include the site and facility layout, hazards, and

emergency services at the site, and will detail all the provisions contained within this CHASP.

For a HAZWOPER operation, training on the site must be for a minimum of 3 days. Specific

issues that will be addressed include the hazards described in Section 3.0.

4.3 Tailgate Safety Briefings

Before starting work each day or as needed, the Langan HSO will conduct a brief tailgate safety

meeting to assist site personnel in conducting their activities safely. Tailgate meetings will be

documented in Attachment H. Briefings will include the following:

Work plan for the day;

Review of safety information relevant to planned tasks and environmental conditions;

New activities/task being conducted;

Results of Jobsite Safety Inspection Checklist;

Changes in work practices;

Safe work practices; and

Discussion and remedies for noted or observed deficiencies.

5.0 MEDICAL SURVEILLANCE

All personnel who will be performing field work involving potential exposure to toxic and

hazardous substances (defined by 29 CFR 1910.120(a)) will be required to have passed an initial

baseline medical examination, with follow-up medical exams thereafter, consistent with 29 CFR

1910.120(f). Medical evaluations will be performed by, or under the direction of, a physician

board-certified in occupational medicine.

Additionally, personnel who may be required to perform work while wearing a respirator must

receive medical clearance as required under CFR 1910.134(e), Respiratory Protection. Medical

evaluations will be performed by, or under the direction of, a physician board-certified in

occupational medicine. Results of medical evaluations are maintained by the HSM.

6.0 COMMUNITY AIR MONITORING PROGRAM

Community air monitoring may be conducted in compliance with the NYSDOH Generic CAMP

outlined below:

Monitoring for dust and odors will be conducted during all ground intrusive activities by the FTL.

Continuous monitoring on the perimeter of the work zones for odor, VOCs, and dust may be

required for all ground intrusive activities such as soil excavation and handling activities. The

Construction Health & Safety Plan November 2016

181 Mercer Street Page 14

New York, New York

Langan Project No. 170001401

work zone is defined as the general area in which machinery is operating in support of

remediation activities. A portable PID will be used to monitor the work zone and for periodic

monitoring for VOCs during activities such as soil and groundwater sampling and .soil

excavation. The site perimeter will be monitored for fugitive dust emissions by visual

observations as well as instrumentation measurements (if required). When required,

particulate or dust will be monitored continuously with real-time field instrumentation that will

meet, at a minimum, the performance standards from DER-10 Appendix 1B.

If VOC monitoring is required, the following actions will be taken based on VOC levels

measured:

If total VOC levels exceed 5 ppm above background for the 15-minute average at the

perimeter, work activities will be temporarily halted and monitoring continued. If levels

readily decrease (per instantaneous readings) below 5 ppm above background, work

activities will resume with continued monitoring.

If total VOC levels at the downwind perimeter of the hot zone persist at levels in excess

of 5 ppm above background but less than 25 ppm, work activities will be halted, the

source of vapors identified, corrective actions taken to abate emissions, and monitoring

continued. After these steps work activities will resume provided that the total organic

vapor level 200 feet downwind of the hot zone or half the distance to the nearest

potential receptor or residential/commercial structure, whichever is less – but in no case

less than 20 feet, is below 5 ppm above background for the 15-minute average.

If the total VOC level is above 25 ppm at the perimeter of the hot zone, activities will be

shutdown.

If dust monitoring with field instrumentation is required, the following actions will be taken

based on instrumentation measurements:

If the downwind particulate level is 100 micrograms per cubic meter (µg/m³) greater

than background (upwind perimeter) for the 15-minute period or if airborne dust is

observed leaving the work area, then dust suppression must be employed. Work may

continue with dust suppression techniques provided that downwind PM10 levels do not

exceed 150 µg/m³ above the background level and provided that no visible dust is

migrating from the work area.

If, after implementation of dust suppression techniques, downwind PM10 levels are

greater than 150 µg/m³ above the background level, work must be stopped and a re-

evaluation of activities initiated. Work can resume provided that dust suppression

measures and other controls are successful in reducing the downwind PM10

concentration to within 150 µg/m³ of the upwind level and in preventing visible dust

migration.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 15

New York, New York

Langan Project No. 170001401

6.1 Vapor Emission Response Plan

This section applies if VOC monitoring is required. If the ambient air concentration of organic

vapors exceeds 5 ppm above background at the perimeter of the hot zone, boring and well

installation, and excavation activities will be halted or odor controls will be employed, and

monitoring continued. When work shut-down occurs, downwind air monitoring as directed by

the HSO or FTL will be implemented to ensure that vapor emission does not impact the

nearest residential or commercial structure at levels exceeding those specified in the Major

Vapor Emission section.

If the organic vapor level decreases below 5 ppm above background, sampling and boring and

well installation can resume, provided:

The organic vapor level 200 feet downwind of the hot zone or half the distance to the

nearest residential or commercial structure, whichever is less, is below 1 ppm over

background, and

More frequent intervals of monitoring, as directed by the HSO or FTL, are conducted.

6.2 Major Vapor Emission

This section applies if VOC monitoring is required. If any organic levels greater than 5 ppm over

background are identified 200 feet downwind from the work site, or half the distance to the

nearest residential or commercial property, whichever is less, all work activities must be halted

or odor controls must be implemented.

If, following the cessation of the work activities, or as the result of an emergency, organic

levels persist above 5 ppm above background 200 feet downwind or half the distance to the

nearest residential or commercial property from the hot zone, then the air quality must be

monitored within 20 feet of the perimeter of the nearest residential or commercial structure (20

Foot Zone).

If either of the following criteria is exceeded in the 20 Foot Zone, then the Major Vapor

Emission Response Plan shall automatically be implemented.

Sustained organic vapor levels approaching 5 ppm above background for a period of

more than 30 minutes, or

Organic vapor levels greater than 5 ppm above background for any time period.

6.3 Major Vapor Emission Response Plan

Upon activation, the following activities will be undertaken:

The local police authorities will immediately be contacted by the HSO or FTL and

advised of the situation;

Frequent air monitoring will be conducted at 30-minute intervals within the 20 Foot

Construction Health & Safety Plan November 2016

181 Mercer Street Page 16

New York, New York

Langan Project No. 170001401

Zone. If two successive readings below action levels are measured, air monitoring may

be halted or modified by the HSO or FTL; and

All Emergency contacts will go into effect as appropriate.

6.4 Dust Suppression Techniques

Preventative measures for dust generation may include wetting site fill and soil, construction of

an engineered construction entrance with gravel pad, a truck wash area, covering soils with

tarps, and limiting vehicle speeds to five miles per hour.

Work practices to minimize odors and vapors include limiting the time that the excavations

remain open, minimizing stockpiling of contaminated-source soil, and minimizing the handling

of contaminated material. Offending odor and organic vapor controls may include the

application of foam suppressants or tarps over the odor or VOC source areas. Foam

suppressants may include biodegradable foams applied over the source material for short-term

control of the odor and VOCs.

If odors develop and cannot be otherwise controlled, additional means to eliminate odor

nuisances will include: direct load-out of soils to trucks for off-Site disposal; use of chemical

odorants in spray or misting systems; and, use of staff to monitor odors in surrounding

neighborhoods.

Where odor nuisances have developed during remedial work and cannot be corrected, or

where the release of nuisance odors cannot otherwise be avoided due to on-site conditions or

close proximity to sensitive receptors, odor control will be achieved by sheltering excavation

and handling areas under tented containment structures equipped with appropriate air

venting/filtering systems.

7.0 PERSONAL PROTECTIVE EQUIPMENT

7.1 Levels of Protection

Langan will provide PPE to Langan employees to protect them from the specific hazards they

are likely to encounter on-site. Direct hired contractors will provide their employees with

equivalent PPE to protect them from the specific hazards likely to be encountered on-site.

Selection of the appropriate PPE must take into consideration: (1) identification of the hazards

or suspected hazards; (2) potential exposure routes; and, (3) the performance of the PPE

construction (materials and seams) in providing a barrier to these hazards.

Based on anticipated site conditions and the proposed work activities to be performed at the

site, Level D protection will be used. The upgrading/downgrading of the level of protection will

be based on continuous air monitoring results as described in Section 6.0 (when applicable).

The decision to modify standard PPE will be made by the site HSO or FTL after conferring with

the PM. The levels of protection are described below.

waist

Leave immediately without

debate

Hands on top of head Need assistance

Thumbs up OK; I'm alright; I understand

Thumbs down No; negative

Simulated "stick" break with fists Take a break; stop work

8.2 Work Zones

The need to formally establish specific work zones (Support, Contamination Reduction, and

Exclusion Zones) during site activities will be determined by the HSO or FTL. It is important for

the safety of all concerned that appropriate barriers (cones, wooden horses, plastic fencing etc.)

are in place to keep vehicles and pedestrians away from the Work Zone.

8.2.1 Exclusion Zone

Exclusion zones or hot zones will be established within a 25 foot radius around drilling and

sampling activities involving hazardous materials, where applicable and feasible. All personnel

within the hot zone must don the appropriate levels of personal protection as set forth by the

HSO. It is not anticipated that Level C or higher will be required for this site.

All personnel within the hot zone will be required to use the specified level of protection. No

food, drink, or smoking will be allowed in the hot or warm zones.

8.2.2 Contamination Reduction Zone

If PID VOC concentration action levels are exceeded or obvious indications of contamination (by

sight or odor) are encountered, a contamination reduction zone or warm zone will be

established and utilized during the field activities. This zone will be established between the

hot zone and the cold zone (discussed below), and will include the personnel and equipment

necessary for decontamination of equipment and personnel exiting the hot zone. Personnel

and equipment in the hot zone must pass through this zone before entering the cold zone. This

zone should always be located upwind of the hot zone.

8.2.3 Support Zone

The support zone or cold zone will include the remaining areas of the job site. Break areas and

support facilities (include equipment storage and maintenance areas) will be located in this

zone. No equipment or personnel will be permitted to enter the cold zone from the hot zone

without passing through the decontamination station in the warm zone (if necessitated).

Eating, smoking, and drinking will be allowed only in this area.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 19

New York, New York

Langan Project No. 170001401

8.3 The Buddy System

When working in teams of two or more, workers will use the "buddy system" for all work

activities to ensure that rapid assistance can be provided in the event of an emergency. This

requires work groups to be organized such that workers can remain close together and

maintain visual contact with one another. Workers using the "buddy system" have the following

responsibilities:

Provide his/her partner with assistance.

Observe his/her partner for signs of chemical or heat exposure.

Periodically check the integrity of his/her partner's PPE.

Notify the HSO or other site personnel if emergency service is needed.

9.0 NEAREST MEDICAL ASSISTANCE

The address and telephone number of the nearest hospital:

Beth Israel Medical Center

First Avenue and 16th Street, New York, NY

212-420-2000

Map with directions to the hospital are shown in Figure 2. This information will either be

posted prominently at the site or will be available to all personnel all of the time. Further, all

field personnel, including the HSO & FTL, will know the directions to the hospital.

10.0 STANDING ORDERS/SAFE WORK PRACTICES

The standing orders, which consist of a description of safe work practices that must always be

followed while on-site by Langan employees and contractors, are shown in Attachment A. The

site HSO and FTL each have the responsibility for enforcing these practices. The standing

orders will be posted prominently at the site, or are made available to all personnel at all times.

Those who do not abide by these safe work practices will be removed from the site.

11.0 SITE SECURITY

No unauthorized personnel shall be permitted access to the work areas.

12.0 UNDERGROUND UTILITIES

As provided in Langan’s Underground Utility Clearance Guidelines, the following safe work

practices should be followed by Langan personnel and the contractor before and during

subsurface work in accordance with federal, state and local regulations:

Obtain available utility drawings from the property owner/client or operator.

Provide utility drawings to the project team.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 20

New York, New York

Langan Project No. 170001401

In the field, mark the proposed area of subsurface disturbance (when possible).

Ensure that the utility clearance system has been notified.

Ensure that utilities are marked before beginning subsurface work.

Discuss subsurface work locations with the owner/client and contractors.

Obtain approval from the owner/client and operators for proposed subsurface work

locations.

Use safe digging procedures when applicable.

Stay at least 10 feet from all equipment performing subsurface work.

13.0 SITE SAFETY INSPECTION

The Langan HSO or alternate will check the work area daily, at the beginning and end of each

work shift or more frequently to ensure safe work conditions. The HSO or alternate must

complete the Jobsite Safety Inspection Checklist, found in Attachment F. Any deficiencies

shall be shared with the FTL, HSM and PM and will be discussed at the daily tailgate meeting.

14.0 HAND AND POWER TOOLS

All hand- and electric-power tools and similar equipment shall be maintained in a safe operating

condition. All electric-power tools must be inspected before initial use. Damaged tools shall be

removed immediately from service or repaired. Tools shall be used only for the purpose for

which they were designed. All users must be properly trained in their safe operation.

15.0 DECONTAMINATION PLAN

15.1 General

All personnel, equipment, and samples leaving the contaminated area of the site must be

decontaminated. Decontamination for this operation is achieved through physical removal and

chemical detoxification/disinfection/sterilization. The first step in decontamination, however, is

prevention and standard operating procedures have been established meant to minimize

contact with wastes:

Work habits that minimize contact with wastes are stressed.

Disposable equipment, where appropriate, will be used.

15.2 Decontamination Procedures

Standard decontamination procedures will be used as described in Attachment B.

15.3 Disposal of Decontamination Wastes

Waste solutions generated during decontamination procedures shall be contained, collected,

and stored in drums or other appropriate containers and labeled for proper off-site disposal.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 21

New York, New York

Langan Project No. 170001401

16.0 EMERGENCY RESPONSE

16.1 General

Due to hazards that may be present at the site and the conditions under which operations are

conducted, it is possible that an emergency situation may develop. Emergency situations can

be characterized as injury or acute chemical exposure to personnel, fire or explosion,

environmental release, or hazardous weather conditions.

16.2 Responsibilities

Site Emergency Coordinator - The HSO, or his/her alternate, will serve as the Site Emergency

Coordinator and shall implement emergency procedures whenever conditions warrant such

action. The Site Emergency Coordinator will be responsible for assuring the evacuation,

emergency treatment, emergency transport of site personnel, and notification of emergency

units and the appropriate management staff. Emergency response instructions will be provided

by the HSO as part of every employee's training prior to the start of work.

Employees - All employees at the site will be familiar with emergency response procedures for

this work location.

16.3 Evacuation

In the event of an emergency situation, an air horn or vehicle horn will be sounded three times

indicating the initiation of evacuation procedures. Loud voice command, if appropriate, can be

used. All personnel will evacuate and assemble at the site entrance. No one, except the

emergency responders, will be allowed to proceed into the area once the emergency signal has

been given. The Site Emergency Coordinator will ensure that access for emergency equipment

is provided and that all sources of combustion (e.g., operating machinery, etc.) have been shut

down once the alarm has been sounded. Wind direction will be taken into consideration for

evacuation plans. Evacuation plans will be discussed at the initial Site-Specific Training and as

needed at the regular safety briefings.

In all situations, when an on-site emergency results in an evacuation, personnel shall not

re-enter until:

The conditions resulting in the emergency have been corrected.

The hazards have been reassessed.

This CHASP has been reviewed.

Site personnel have been briefed on any changes to this CHASP.

16.4 Emergency Contacts/Notification System

The fire department and other emergency response groups will be notified by telephone of the

emergency as soon as possible. An emergency telephone numbers list is presented as Table 5

Construction Health & Safety Plan November 2016

181 Mercer Street Page 22

New York, New York

Langan Project No. 170001401

in this CHASP. This list will either be posted prominently at the site or will be made readily

available to all personnel all of the time.

16.5 Emergency Medical Treatment

Personnel Injury - In case of injury to personnel, the HSO or his/her alternate will immediately

administer emergency first aid. The ambulance/rescue squad will also be contacted as

necessary. Some situations may require transport of the injured parties by automobile.

Therefore, maps/directions to the nearest hospital are provided as Figure 2. Figure 2 will either

be posted at the site, or will be made readily available to all personnel all of the time.

Personnel Exposure – Emergency first aid procedures to be followed are:

Skin Contact: Use copious amounts of soap and water. Wash/rinse affected areas

thoroughly, and then provide appropriate medical attention. Rinse eyes with water for

at least 15 minutes.

Inhalation: Move to fresh air and/or, if necessary decontaminate and transport to

emergency medical facility.

Ingestion: Decontaminate and transport to emergency medical facility.

Puncture/Laceration: Decontaminate, if possible, and transport to emergency medical

facility.

16.6 Fire or Explosion

Appropriate fire extinguishers will be made available at the site for trained personnel to use on

insipient stage fires without endangering the safety and health of those nearby. If the use of

fire extinguishers will not extinguish the fire, immediately notify the fire department, sound the

evacuation signal, and then evacuate the area, assembling at the site entrance to be accounted

for and to receive further instruction.

16.7 Spills/Leaks

Control or stop the spread of minor chemical spills or contamination by utilizing the appropriate

materials (absorbents, etc.), if possible. If the release is significant, or highly hazardous,

immediately notify the appropriate response groups, sound the evacuation signal, evacuate the

area, and assemble at the site entrance to be accounted for and to receive further instruction.

16.8 Adverse Weather Conditions

In the event of severe weather (rain, snow, sleet, heat, etc.), conditions will be assessed on

site to determine if the work can proceed safely. If it is determined that the weather poses a

significant hazard, site operations will be stopped and rescheduled. Some of the items to be

considered prior to determining if work should continue include:

Potential for heat stress and heat-related injuries.

Construction Health & Safety Plan November 2016

181 Mercer Street Page 23

New York, New York

Langan Project No. 170001401

Potential for cold stress and cold-related injuries.

Treacherous weather-related working conditions including thunder storms. When

thunderstorms do occur, work is to cease immediately while personnel seek shelter.

Work cannot resume until 30 minutes after the last thunder clap.

Limited visibility.

TABLE 3

Summary of Monitoring Equipment

Instrument Operation Parameters

Photoionization

Detector (PID)

Hazard Monitored: Many organic and some inorganic gases and vapors.

Application: Detects total concentration of many organic and some inorganic gases and

vapors. Some identification of compounds is possible if more than one probe is

measured.

Detection Method: Ionizes molecules using UV radiation; produces a current that is

proportional to the number of ions.

General Care/Maintenance: Recharge or replace battery. Regularly clean lamp

window. Regularly clean and maintain the instrument and accessories.

Typical Operating Time: 10 hours. 5 hours with strip chart recorder.

Oxygen Meter Hazard Monitored: Oxygen (O2).

Application: Measures the percentage of O2 in the air.

Detection Method: Uses an electrochemical sensor to measure the partial pressure of

O2 in the air, and converts the reading to O2 concentration.

General Care/Maintenance: Replace detector cell according to manufacturer’s

recommendations. Recharge or replace batteries prior to explanation of the specified

interval. If the ambient air is less than 0.5% C O2 , replace the detector cell frequently.

Typical Operating Time: 8 – 12 hours.

Additional equipment (if needed, based on site conditions)

Combustible Gas

Indicator (CGI)

Hazard Monitored: Combustible gases and vapors.

Application: Measures the concentration of combustible gas or vapor.

Detection Method: A filament, usually made of platinum, is heated by burning the

combustible gas or vapor. The increase in heat is measured. Gases and vapors are

ionized in a flame. A current is produced in proportion to the number of carbon atoms

present.

General Care/Maintenance: Recharge or replace battery. Calibrate immediately before

use.

Typical Operating Time: Can be used for as long as the battery lasts, or for the

recommended interval between calibrations, whichever is less.

Flame Ionization

Detector (FID) with

Gas Chromatography

Option

(i.e., Foxboro Organic

Vapor Analyzer (OVA))

Hazard Monitored: Many organic gases and vapors (approved areas only).

Application: In survey mode, detects the concentration of many organic gases and

vapors. In gas chromatography (GC) mode, identifies and measures specific compounds.

In survey mode, all the organic compounds are ionized and detected at the same time.

In GC mode, volatile species are separated.

General Care/Maintenance: Recharge or replace battery. Monitor fuel and/or

combustion air supply gauges. Perform routine maintenance as described in the manual.

Check for leaks.

Typical Operating Time: 8 hours; 3 hours with strip chart recorder.

Potable Infrared (IR)

Spectrophotometer

Hazard Monitored: Many gases and vapors.

Application: Measures concentration of many gases and vapors in air. Designed to

quantify one or two component mixtures.

Detection Method: Passes different frequencies of IR through the sample. The

frequencies absorbed are specific for each compound.

General Care/Maintenance: As specified by the manufacturer.

Instrument Operation Parameters

Direct Reading

Colorimetric Indicator

Tube

Hazard Monitored: Specific gas and vapors.

Application: Measures concentration of specific gases and vapors.

Detection Method: The compound reacts with the indicator chemical in the tube,

producing a stain whose length or color change is proportional to the compound’s

concentration.

General Care/Maintenance: Do not use a previously opened tube even if the indicator

chemical is not stained. Check pump for leaks before and after use. Refrigerate before

use to maintain a shelf life of about 2 years. Check expiration dates of tubes. Calibrate

pump volume at least quarterly. Avoid rough handling which may cause channeling.

Aerosol Monitor Hazard Monitored: Airborne particulate (dust, mist, fume) concentrations

Application: Measures total concentration of semi-volatile organic compounds, PCBs,

and metals.

Detection Method: Based on light-scattering properties of particulate matter. Using an

internal pump, air sample is drawn into the sensing volume where near infrared light

scattering is used to detect particles.

General Care/Maintenance: As specified by the mfr. Also, the instrument must be

calibrated with particulates of a size and refractive index similar to those to be measured

in the ambient air.

Monitox Hazard Monitored: Gases and vapors.

Application: Measures specific gases and vapors.

Detection Method: Electrochemical sensor relatively specific for the chemical species

in question.

General Care/Maintenance: Moisten sponge before use; check the function switch;

change the battery when needed.

Gamma Radiation

Survey Instrument

Hazard Monitored: Gamma Radiation.

Application: Environmental radiation monitor.

Detection Method: Scintillation detector.

General Care/Maintenance: Must be calibrated annually at a specialized facility.

Typical Operating Time: Can be used for as long as the battery lasts, or for the

recommended interval between calibrations, whichever is less.

INSTRUMENTATION ACTION LEVELS

Photoionization Detector Action Levels Action Required

Background to 5 ppm No respirator; no further action required

> 1 ppm but < 5 ppm for > 5 minutes 1. Temporarily discontinue all activities and

evaluate potential causes of the excessive

readings. If these levels persist and cannot be

mitigated (i.e., by slowing drilling or excavation

activities), contact HSO to review conditions and

determine source and appropriate response

action.

2. If PID readings remain above 1 ppm,

temporarily discontinue work and upgrade to

Level C protection.

3. If sustained PID readings fall below 1 ppm,

downgrading to Level D protection may be

permitted.

> 5 ppm but < 150 ppm for > 5 minutes 1. Discontinue all work; all workers shall move to

an area upwind of the jobsite.

2. Evaluate potential causes of the excessive

readings and allow work area to vent until VOC

concentrations fall below 5 ppm.

3. Level C protection will continue to be used until

PID readings fall below 1 ppm.

> 150 ppm Evacuate the work area

Notes: 1. 1 ppm level based on OSHA Permissible Exposure Limit (PEL) for benzene.

2. 5 ppm level based on OSHA Short Term Exposure Limit (STEL) maximum exposure

for benzene for any 15 minute period.

3. 150 ppm level based on NIOSH Immediately Dangerous to Life and Health (IDLH) for

tetrachloroethylene.

STANDING ORDERS

STANDING ORDERS

GENERAL

No smoking, eating, or drinking in this work zone.

Upon leaving the work zone, personnel will thoroughly wash their hands and face.

Minimize contact with contaminated materials through proper planning of work areas and

decontamination areas, and by following proper procedures. Do not place equipment on the

ground. Do not sit on contaminated materials.

No open flames in the work zone.

Only properly trained and equipped personnel are permitted to work in potentially

contaminated areas.

Always use the appropriate level of personal protective equipment (PPE).

Maintain close contact with your buddy in the work zone

Contaminated material will be contained in the Exclusion Zone (EZ).

Report any unusual conditions.

Work areas will be kept clear and uncluttered. Debris and other slip, trip, and fall hazards

will be removed as frequently as possible.

The number of personnel and equipment in the work zone will be kept to an essential

minimum.

Be alert to the symptoms of fatigue and heat/cold stress, and their effects on the normal

caution and judgment of personnel.

Conflicting situations which may arise concerning safety requirements and working

conditions must be addressed and resolved quickly by the site HSO.

TOOLS AND HEAVY EQUIPMENT

Do not, under any circumstances, enter or ride in or on any backhoe bucket, materials hoist,

or any other device not specifically designed to carrying passengers.

Loose-fitting clothing or loose long hair is prohibited around moving machinery.

Ensure that heavy equipment operators and all other personnel in the work zone are using

the same hand signals to communicate.

Drilling/excavating within 10 feet in any direction of overhead power lines is prohibited.

The locations of all underground utilities must be identified and marked out prior to initiating

any subsurface activities.

Check to insure that the equipment operator has lowered all blades and buckets to the

ground before shutting off the vehicle.

If the equipment has an emergency stop device, have the operator show all personnel its

location and how to activate it.

Help the operator ensure adequate clearances when the equipment must negotiate in tight

quarters; serve as a signalman to direct backing as necessary.

Ensure that all heavy equipment that is used in the Exclusion Zone is kept in that zone until

the job is done, and that such equipment is completely decontaminated before moving it

into the clean area of the work zone.

Samplers must not reach into or get near rotating equipment such as the drill rig. If

personnel must work near any tools that could rotate, the equipment operator must

completely shut down the rig prior to initiating such work. It may be necessary to use a

remote sampling device.

EQUIPMENT DECONTAMINATION

GENERAL:

Equipment to be decontaminated during the project may include tools, monitoring equipment,

respirators, sampling containers, laboratory equipment and drilling equipment.

All decontamination will be done by personnel in protective gear, appropriate for the level of

decontamination, as determined by the site HSO. The decontamination work tasks will be split or

rotated among support and work crews.

Depending on site conditions, backhoe and pumps may be decontaminated over a portable

decontamination pad to contain wash water; or, wash water may be allowed to run off into a storm

sewer system. Equipment needed may include a steam generator with high-pressure water, empty

drums, screens, screen support structures, and shovels. Drums will be used to hold contaminated

wash water pumped from the lined pit. These drums will be labeled as such.

Miscellaneous tools and equipment will be dropped into a plastic pail, tub, or other container. They

will be brushed off and rinsed with a detergent solution, and finally rinsed with clean water.

MONITORING EQUIPMENT:

Monitoring equipment will be protected as much as possible from contamination by draping,

masking, or otherwise covering as much of the instruments as possible with plastic without

hindering the operation of the unit. The PID, HNu or OVA meter, for example, can be placed in a

clear plastic bag, which allows reading of the scale and operation of knobs. The probes can be

partially wrapped keeping the sensor tip and discharge port clear.

The contaminated equipment will be taken from the drop area and the protective coverings

removed and disposed in the appropriate containers. Any dirt or obvious contamination will be

brushed or wiped with a disposable paper wipe.

RESPIRATORS:

Respirators will be cleaned and disinfected after every use. Taken from the drop area, the masks

(with the cartridges removed and disposed of with other used disposable gear) will be immersed in

a cleaning solution and scrubbed gently with a soft brush, followed by a rinse in plain warm water,

and then allowed to air dry. In the morning, new cartridges will be installed. Personnel will inspect

their own masks for serviceability prior to donning them. And, once the mask is on, the wearer will

check the respirator for leakage using the negative and positive pressure fit check techniques.
