SITE MANAGEMENT PLAN

The purpose of the SMP is to provide EPA with a written description of how various project tasks such

as identifying abutting properties, access procedures, site access control, personnel organization and

responsibilities, waste material management, data management system, and monitoring and reporting

measures are to be managed by the Settling Parties.

This SMP constitutes the first portion of the Project Operations Plan (POP); the POP also includes a

Sampling and Analysis Plan (SAP), a Site Health & Safety Plan (HSP) and a Community Relations

Support Plan (CRSP). The SMP is subject to USEPA's review and revisions prior to the implementation

of the field work at Gallup's Quarry Superfund Site.

SMP-4; 08/29/94

1.0 PROJECT LAYOUT AND SITE CONTROL

The Gallup's Quarry site is located off Tarbox Road in the town of Plainfield, Windham County,

Connecticut, as shown on Figure A-l, Project Locus. Project layout for the Gallup's Quarry site includes

identifying the existing site conditions, work zones, project support measures and provisions for support

of site workers during implementation of the RI/FS Work Plan. A Site Plan showing some safety

provisions, along with overall existing site conditions and proposed location of project support facilities,

is contained in this SMP, as Figure A-2. For the purpose of this SMP the term "site" refers to the limits

of the property owned by C. Stanton Gallup.

1.1 WORK ZONES

Existing site conditions for the Gallup's Quarry Site are described in Section HI, Surface and Subsurface

Conditions, of the RI/FS Work Plan. Three former contaminant source areas and two potential source

areas have been identified at the site. These consist of the following areas:

• Primary Barrel Pit and Chemical Lagoon

• Secondary Barrel Pit and Liquid Burial Area

• Barrel Seepage Bed

• Two suspected former Connecticut D.O.T Asphalt Mix Plants

If additional contaminant source areas are identified during the initial surface soil screening portion of

the field work, then additional source-area work zones will be established. Vork zones will be clearly

delineated and posted to reduce the potential for accidental spread of hazardous substances by workers

from contaminated areas to clean areas. These zones consist of an exclusion zone, contamination

reduction zone, and the support zone as described below. The HSP contained in Appendix D, provides

additional information on work zones.

1.1.1 Exclusion Zones

The exclusion zone is the area where the highest potential for exposure by dermal or inhalation routes

exists. Activities performed in the exclusion zone include site characterization and soil borings.

The level of personnel protective equipment (PPE) required in the exclusion zone is defined by the Health

& Safety Plan (HSP). More than one restricted area within the exclusion zone may be established when

different levels of protection are required. A daily log will be kept of all personnel entering and exiting

this zone, the tasks performed, and health and safety protocols followed.

SMP-5; 08/29/94

Some exclusion zones wi l l be task specific. For example, the area marked as part of the support zone

during the geophysical survey may later be designated an exclusion zone during dri l l ing operations. The

five areas described above have been identified as containing the potential for exposure by dermal or

inhalation routes (possible exclusion zones) due to known or suspected surficial contamination. More

exclusion zones may be identified as additional information is obtained during field activities. The five

exclusion zones presently identified are shown as stippled areas in Figure A-2. These areas include the

two barrel pits, seepage bed and two possible former D.O.T. asphalt plant locations.

The exclusion zone will be marked off with barricades or barrier tape placed a minimum of 50 feet from

the active work area. During field operations this boundary may be expanded by the field team leader

based upon observations and/or monitoring measurements. The locations and descriptions of the previous

activities, and known conditions, at these areas are described in the RI/FS Work Plan in Section II,

Background Information, and Section III, Surface and Subsurface Conditions. An initial site

reconnaissance, described in Section 1.4, will help to identify the limits of areas to be designated

exclusion zones based on visual observation and monitoring measurements. Table A-3 (Action Levels

and Responses) lists monitoring equipment required inside and outside the exclusion zone and at what

action levels the exclusion zone will be extended.

1.1.2 Contamination Reduction Zone

The contamination reduction zone is the transition area located immediately adjacent to and upwind of

the exclusion zone. The contamination reduction zone will include facilities for personnel and equipment

decontamination as described in the HSP. Each exclusion zone will have or share a contamination

reduction zone. Table A-3 (Action Levels and Responses) lists monitoring equipment required inside and

outside the contamination reduction zone.

1.1.3 Support Zone

The support zone covers all areas outside the exclusion zone and the contamination reduction zone. The

support zone will include the command post, facilities for a field office, and equipment and material

storage. Emergency support information will be available in the Support Zone. Details of the Support

Zone are also provided in the HSP. Table A-3 (Action Levels and Responses) lists monitoring required

inside and outside the support zone.

SMP - 6; 08/29/94

1.2 PROJECT SUPPORT MEASURES

Field activities will be supported by locating a field office trailer equipped with electricity and telephone

on the Gallup's Site. The field office will be maintained throughout the implementation of the RI/FS

Work Plan field activities.

The field office will be located within an enclosed security fence on the southwestern portion of the site

approximately 10-20 feet from the main entrance (as allowed bv local ordinance), as shown on Figure

A-2. Such field offices available for rental are typically 8 feet wide with lengths varying from 16 to 32

feet long. The size selected will be appropriate for the level of activity anticipated during the RI/FS

Work Plan field activities.

Telephone service will be provided in the field office to facilitate normal business and emergency

communications. The field office will also be equipped with a desk, plans table, fire extinguisher,

portable eye wash and drench hose, as well as some personnel amenities. The office will also serve as

the coordination location for emergency procedures and will have emergency telephone numbers,

evacuation routes, and maps to local hospitals posted.

Portable sanitary facilities will be provided adjacent to the field office. The field office will be used to

support field activities by providing the following services:

• Emergency procedure information

• Sign in and sign out sheets

• Daily field activity log book

• Health & Safety log book

• Storage of Personal Protective Equipment (PPE)

• Communications center

• Posting of project plans

• Briefing/Meeting room to coordinate field activities

• Meeting place for emergency evacuations

• Lunch area

Written directions and a map showing access to nearby medical facilities (Figure a-4) will be posted in

site vehicles as well as in the Support Zone.

SMP-7; 08/29/94

2.0 ACCESS TO ABUTTING PROPERTIES

It wi l l be necessary to have access to some abutting properties to conduct investigations and long-term

monitoring.

Information on ownership and boundaries for properties adjacent to the site was obtained from the Town

of Plainfield, Tax Assessor's Office. The approximate location and boundaries of the property are shown

on the Property Boundaries Plan, attached as Figure A-3.

A list of the abutting property owners' names, addresses and telephone numbers is set out in

Table A-1.

2.1 PROCEDURES TO OBTAIN ACCESS

The authority to access abutting properties, when access is required to determine the sources or extent

of groundwater and soil contamination, is stated in the Comprehensive Environmental Response,

Compensation and Liability Act (Superfund), 42 U.S.C. Section 9601. Access to abutting properties,

for investigation purposes, was requested on 19 November 1993. A copy of the access request letter is

included as Attachment 1. This letter contains an acknowledgement to be completed by the properties'

owners indicating their willingness to allow access to their property.

SMP-8; 08/29/94

3.0 SITE ACCESS CONTROL

Access control will be provided at the site for general citizen security and for the security of government

and private property on the site. Security measures are necessary for the following reasons:

• Prevent the exposure of unauthorized, unprotected people to site hazards.

• Avoid additional contamination from vandals disturbing investigation derived waste or

from persons seeking to abandon other wastes on the site.

• Prevent theft.

• Avoid interference with safe working procedures.

As discussed below, security measures will include fencing, gates, signage, and communication with local

police.

ESE, Inc. will arrange and control access to the Gallup's property. Persons seeking entrance to the

property will have to make arrangements through the Project Coordinator, W. Gary Wilson. All visitors

will be required to sign in and out in a visitors log which will be maintained in the site office and will

be accompanied by the Site Manager (or another designated representative). Under no circumstances will

visitors be allowed to enter designated exclusion zones unless authorized by both the Site Health and

Safety Officer and the Project Coordinator

3.1 GALLUP'S PROPERTY PERIMETER CONDITIONS

The Gallup's property is bordered on the east by Route 12 and private residences, a railroad right-of-way

to the west, an undeveloped property including Mill Brook and wetlands to the north, and Tarbox Road

to the south. The railroad tracks, and Mill Brook and wetlands, act as natural access control measures,

however, iignage will be placed as described in Section 3.1.3, along these areas to provide additional site

control.

There are four obvious locations where vehicles can enter the Gallup's property. These are shown on

Figure A-2. The main entrance to the property is located on the southwest portion off Tarbox Road.

Another possible entrance is located in the southeast corner of the site along Tarbox Road. The two

remaining entrances, which might allow small off-road vehicles to pass, are located on the eastern portion

SMP-9; 08/29/94

of the site, one extending from Route 12 approximately 540 ft. from Tarbox Road, and the other passing

from Route 12 through an occupied abutter's property about 1100 ft. from Tarbox Road.

The remainder of the perimeter of Jic Gallup's property is heavily wooded and presently inaccessible to

vehicular traffic.

3.1.1 Fencing and Gates

The southwest entrance to the site on Tarbox Road will be used as the main entrance during field

operations. This main entrance will be secured with a six foot high chain-link gate and fence extending

west from the main entrance to the railway right-of-way and east until it meets existing heavy vegetation.

The total length of fencing is expected not to exceed 100 ft. This combination of fencing, railroad tracks

and heavy vegetation should restrict access by unauthorized vehicles attempting to enter the site from

Tarbox Road.

The three other entrances will be blocked with a row of boulders, a minimum of 3 ft. in diameter.

Access through these entrances has been primarily by all-terrain type vehicles. Existing heavy vegetation

and stone walls, in addition to the row of boulders, should sufficiently restrict access by these vehicles

at other entrances. Warning signage will be used to restrict public access by foot.

Inside the site, adjacent to the entrance, a security fence and gate shall be placed around the field office.

A separate fenced-in area with its own gates will be constructed as a temporary holding area for

investigation derived wastes. This area will include a solids management area, drum management area

(for liquids), and a decontamination area, as shown on Figure A-6. A description of the materials to be

managed in this area are included in Section V, Waste Material Management Plan.

The main entrance will be the access control point for the site and have the only gate allowing vehicles

and equipment to enter and exit the Gallup's property.

3.1.2 Signage

Warning signs will be posted on the fenced and unfenced portions of the site perimeter approximately

every 100 feet to advise people attempting to enter the site, hat access is restricted. In accordance with

40 CFR 264.14 signs must be legible from a distance of at least 25 ft. Signs will be a minimum of

approximately 20 in. by 20 in. The signs will contain the following information:

SMP - 10; 08/29/94

WARNING

CONTAMINATED AREA

SITE CONTAINS HAZARDOUS MATERIALS WHICH

MAY BL r-.ARMFUL TO THE PUBLIC HEALTH

NO TRESPASSING

- AUTHORIZED PERSONNEL ONLY

EPA SITE ID# CTD108960972

The signs will be checked periodically, and repaired or replaced when needed.

3.1.3 Local Police Department

The Plainfield Police Department will be asked to have its normal town patrol conduct nightly drive-by

inspections of the site along Tarbox Road. Communications with the police department will be

maintained to insure they are informed of site activities.

3.2 CONTINGENCY AND NOTIFICATION PLAN FOR POTENTIALLY DANGEROUS

ACTIVITIES

The contingency and notification plan for potentially dangerous activities includes emergency response,

task specific HSPs, and community right-to-know provisions. Those requirements are discussed briefly

below.

3.2.1 Emergency Response

During site activities, unpredictable events such as a release of contaminants, physical injury, chemical

exposure, fire or explosion could occur. The emergency response plan, contained in Section XV of the

HSP provides information concerning emergency contacts such as the Hazardous Materials Response

Team (ERT), medical and fire officials and agencies. Figure A4 provides information on the location

of access routes for ambulance response, and location of the nearest medical facilities.

3.2.2 Emergency Response Team

The general procedures for responding to emergencies at the Gallup's Quarry Superfund Site will include

notifying the appropriate Stare and/or local emergency response authorities in accordance with the HSP.

In addition, an emergency response team (ERT) will be under contract to respond in the event of a release

of hazardous materials to the environment. The ERT will provide on-site emergency response capabilities

SMP- 11; 08/29/94

and request assistance from the local emergency response authorities for those emergencies that have the

potential to impact the local community.

The ERT will be notified by the Site Manager of an emergency ciiat requires their services. The ERT

will provide equipment and personnel trained to implement control procedures for fire, explosions, or

release of hazardous materials to the environment. This will include, but not be limited to, coordinating

the emergency response, developing command posts, communication and appropriate notifications.

3.2.3 Notification Procedures

In the event of a potential or actual chemical release which may affect off-site receptors, the Emergency

Notification Flow Chart (Figure A-5) will be followed. Notification will immediately begin with the Site

Health & Safety Officer contacting local fire and emergency response officials who will determine if

notification or evacuation of nearby residences is required. The Project Coordinator, W. Gary Wilson,

will then be contacted and briefed on the emergency situation. The Project Coordinator, W. Gary

Wilson, will contact the EPA Remedial Project Manager (RPM) or in the event of EPA's RPM

inavailability the Regional Duty Officer of the Emergency Planning and Response Branch, within 24

hours, and submit a written report within five days.

3.2.4 Chemical Release

In the event a chemical release (such as rupture of a buried drum or excavation of highly contaminated

soils), the following procedures will be implemented immediately:

• All activities will cease and all workers will exit the site to the emergency response

station, (refer to Figure 4-2, Evacuation Route and Emergency Response Station)

• The appropriate protective equipment will be donned by the Field Team and readings

with either the HNU or OVA will be taken along the downwind site border. Air

sampling will be continuous until action levels are no longer exceeded at the exclusion

zone perimeter

• Once air quality levels have been measured (based on PID or FID recordings) these

levels will be reported to the appropriate off-site agency.

Emergency chemical releases will be avoided by the following steps:

SMP - 12; 08/29/94

• Strict compliance with health and safety procedures and protocols

• Continuous observation for signs of an impending chemical reiease

• Air monitoring for indications of the presence of, or increasing amounts of, airborne

contaminants

• A review of previously collected site data for indications of areas where potential

chemical releases may occur

• A continuous review and interpretation of data gathered while performing field work for

indications of where a release may occur.

3.2.5 Task Specific HSP Plan - Action Plan

Task-specific Health and Safety Plans are contained in Attachment 1 of the HSP (Appendix D of the

RI/FS Work Plan). Table D-3 (Action Levels and Responses) presents a summary of the type of hazards,

action levels, notification, and specific actions to be taken during implementation of the work plan tasks

performed at the site.

3.2.6 Community Right-to-Know

Assistance will be provided to EPA in the development and implementation of the Community Relations

Support Plan (CRSP) for the Gallup's Quarry Superfund Site. Such support will be provided at the

request of the EPA and will include, but not be limited to the following:

• participation at public informational meetings, including preparing written materials and

providing visual aids and equipment;

• periodic publications and distribution of fact sheets and other informational materials

describing on-going activities or environmental conditions at the site;

• assistance in the preparation of written responses to significant comments made by the

public, all of which shall be subject to EPA review and approval; and

• assistance in preparing, establishing, and maintaining an administrative record file in the

local area information repository (e.g., library).

SMP - 13; 08/29/94

A notification flow chart containing the order, name, title, and telephone number of people to be

contacted in the event of a release, spill, or other emergency which may impact off-site receptors is

included as Figure A-5.

2. The role of these subcontractors has been discussed throughout the RI/FS Work Plan. The specific

subcontractors will be selected based on experience, availability, and costs.

SMP - 17; 08/29/94

5.0 WASTE MATERIALS MANAGEMENT PLAN (WMMP)

The WMMP is designed to provide a practical approach for managing the waste materials resulting from

work performed in accordance with the RI/FS Work Plan, consistent with applicable regulatory

requirements. Efforts will be taken to minimize the volume of contaminated materials that may ultimately

require management.

This plan also describes measures to be implemented to prevent release of potential waste materials to

the environment and characterization procedures to evaluate treatment and/or disposal options. The

measures to prevent a release of material to the environment include establishing a secured temporary

waste management area including the installation of an impervious bermed pad provide containment.

It is anticipated that work activities will produce three types of waste materials requiring management:

solids consisting of soil and rock drill cuttings; liquids consisting of drilling fluids, well-purge water,

well-development water, and decontamination washwater; and used personnel protective equipment, and

expendable sampling supplies.

The waste materials management plan is consistent with the requirements of RCRA, and applicable state

laws.

5.1 INVESTIGATION DERIVED WASTE (IDW) GENERATION AND DISPOSAL

It is presently anticipated that much of the wastes generated during field activities can appropriately be

containerized in 55-gallon drums. However some field activities may generate more waste than can be

practically stored in 55-gallon drums, in which case larger storage containers will be obtained. These

larger containers may consist of lined roll-offs for bulk storage of solids, and tankers for holding liquids.

Work activities to be performed and the anticipated materials requiring disposal management include:

• Surveying - Personal Protective Equipment (PPE)

• Geophysical survey - PPE

• Soil vapor survey - PPE, decontamination wastes

• Test borings, and well installation and development - PPE, decontamination wastes, soil

and rock cuttings, drilling fluids, well-development water

SMP - 18; 08/29/94

• Groundwater sampling - PPE, decontamination wastes, well-purge water, expendable

supplies

• Surface water and sediment sampling - PPE, decontamination wastes, expendable supplies

Typically, soil and debris produced during implementation of the FSP will be containerized in 55-gallon

drums near the work sites. Liquids produced during decontamination will be removed using pumps,

vacuum trucks or similar equipment and containerized. Residual solids produced during decontamination

will be removed by shovel or other means and placed in a drum. Containers will be filled and labeled

as discussed in Section 5.4 of the WMMP and transferred to the appropriate management area for

subsequent management as described in Section 5.6 of the WWMP. Tankers containing liquids will be

parked adjacent to the decontamination pad. Liquids in the tanker will be characterized as described in

Section 5.6 of the WMMP.

Superfund sites are exempt from permit requirements under CERCLA however the substantive standards

of the regulation must be complied with. Therefore, site managers are not required to comply with

administrative requirements triggered by RCRA storage deadlines. However, before shipping wastes off

site, approval will be obtained for the proposed disposal facility from EPA's Regional Off-site Policy

Coordinator.

Until the final action, IDW may be stored (e.g., drummed, covered waste piles) or returned to its source

provided that this option is protective of human health and the environment and considers ARARs, and

other relevant site specific factors. Storage of RCRA hazardous IDW in . jntainers within the area of

contamination and subsequently returning it to the source will not trigger land disposal restrictions.

Returning soils to their source immediately may be protective; if so it will avoid potentially increased

costs and requirements associated with storage. Chemical test results obtained from soil and groundwater

samples collected from monitoring wells and soil borings will be used to classify containerized IDW.

Drill cuttings from borings will be placed back into the borehole, from which they originated at

approximately the sample depth they existed in-situ.

For well installations outside of source areas, drill cuttings from above the groundwater table will be

temporarily stored on plastic sheeting adjacent to the borehole and covered with plastic sheeting. The

ultimate disposition of all drill cuttings will be determined based on the results of Phase 1A laboratory

testing. Groundwater elevations will be established in these areas based on drilling observations and from

data collected while performing the MicroWell* survey.

SMP - 19; 08/29/94

5.2 TEMPORARY CONTAINER MANAGEMENT/DECONTAMINATION AREA

A temporary on-site container management/decontamination area will be established to manage wastes

generated during field activities and provide a controlled area for decontamination of equipment. Use

of the temporary Container Management/Decontamination area will facilitate the safe management of

wastes and contaminated materials, and reduce the possibility of migration of contamination to

surrounding soil or surface water. The temporary container management/decontamination area will be

designed to provide secondary containment for liquid wastes. This area will be secured by a fence and

located adjacent to the field office, as shown on Figure A-6.

The temporary container management/decontamination area will be graded and lined with textured HOPE

which will be draped over hay bales at the periphery of the area to create a containment berm. In

addition, the pad will be sloped to a common collection trench to allow decontamination water,

precipitation, or spills to be conveyed to a sump and collected into appropriate containers. Tarps will

be used whenever practical to minimize the amount of precipitation which accumulates on the pad.

Drummed solid wastes will be stored in 55 gallon drums at the point of generation (i.e., drilling site).

Drums will be transported to the temporary container management area. Drums will be stored, with

appropriate labeling, in the temporary containment area. Drums of solids may be combined, as detailed

in Section 5.5.1, into roll-off boxes.

A double-walled bulk liquid storage tank will be placed in the temporary containment area. Liquid wastes

will be collected at each drilling site or monitoring well into 55-gallon drums. These drums will be

transported, when full, to the bulk liquid storage tank and the contents puirr^d into the tank.

Liquids will not be allowed to accumulate in excess of the specified maximum volume. The temporary

waste material management area will be constructed large enough to provide segregation of "non

compatible substances", and large enough to accommodate anticipated volumes of containerized waste

and staged clean drums. Overall dimensions are shown on Figure A-6.

Wastes in the temporary container management/decontamination area will be stored with adequate aisle

space so that they are readily accessible to site workers responsible for managing liquid and solid wastes.

Spills will be recovered, contained, and cleaned-up immediately upon detection.

SMP-20; 08/29/94

5.3 CONTAINERS

As discussed in Section 5.1, several different types of containers may be used during various aspects of

implementation of the RI/FS work plan. These containers may include: 55-gallon drums for solids and

liquids; tankers for bulk liquids; and roll-off boxes for bulk solids. Containers used will be selected

based on the suitability of a container to hold the material and compatibility with the material. In

addition, containers used will meet US DOT specifications for transportation.

5.4 CONTAINER LABELLING

Containers such as 55-gallon drums will be used to hold materials produced during implementation of

RI/FS work plans. These containers will be filled near the work site and then moved to the appropriate

container holding area until disposal options are determined. At the work site, an inventory of the type

of materials placed in a drum will be maintained by on-site personnel. Once the container has been filled,

the cover will be securely iastened and the container will be labeled with the following information: site

name, location, date filled, general content type, initials of the person securing the container lid, and the

name and telephone number of a contact person. After the container has been labeled, it will be placed

in the appropriate container management area. An inventory sheet will be maintained to control and

monitor materials placed in tankers and roll-off boxes. The inventory sheet will be maintained by site-

personnel and record the following information: site name, location, date material added, type of material

added, approximate volume of material added, date filled to capacity, initials of the individual recording

the information, and the name and telephone number of a contact person. This inventory sheet will be

kept near the tanker and/or roll-off box location, and will be used when determining disposition of the

material.

5.5 CHARACTERIZATION AND DISPOSITION OF WASTE MATERIALS

5.5.1 Waste Materials in Drums

Drums that have been placed in the container holding area will be characterized to determine the

appropriate disposal option. Where practical, drums containing similar materials will be consolidated for

subsequent management of the material. Prior to individual drum characterization, information provided

from the initial drum filling will be reviewed on a drum-by-drum basis. Drums that contain materials

of similar nature will be consolidated in roll-off boxes or tankers. Once consolidated, a representative

sample of the material in the container will be collected and analyzed for parameters necessary to

determine the appropriate disposal option.

SMP-21; 08/29/94

If the material in the drum is determined not to be similar in nature to other drummed materials, then it

will be characterized individually as described below:

Drums with Solids:

Drums that contain solids will be sampled using a hand auger or other suitable sampling device.

The sample will be transferred to an appropriate sample container and submitted for chemical

analyses as described in Section 5.6 of the WMMP.

5.5.2 Waste Material in Tankers

Liquids containerized in tankers will be tested to determine the appropriate treatment and disposal option.

A representative sample of the liquid in the tanker will be collected using a coliwasa tube or similar

equipment through the access port located on the topside of die tanker. The sample will be transferred

to an appropriate sample container and submitted for chemical analysis as described in Section 5.6 of the

WMMP.

5.5.3 Disposition

The materials produced during the work activities of RI/FS will consist of those materials that may

potentially be considered hazardous or non-hazardous materials. To determine the appropriate treatment

and/or disposal options, representative samples of materials requiring management may be obtained and

tested, depending upon the requirements of the waste hauler and ultimate disposal facility. No wastes

will be manifested without full compliance with applicable RCRA requirements.

A subcontracted licensed waste hauler will remove the wastes generated during field activities or. The

PRP Group will follow the generator responsibilities in compliance with all RCRA requirements.

All waste haulers removing wastes from the Gallup's Quarry Superfund Site will be licensed and have

appropriate EPA identification numbers.

SMP-22; 08/29/94

6.0 DATA MANAGEMENT SYSTEM

6.1 PURPOSE

The purpose of the data management system (DMS) is to organize, store, and present, and facilitate

analyzing and verification of data obtained during implementation of the RI/FS Work Plan. A DMS flow

chart is presented in Figure A-16.

The DMS encompasses the overall management of field and laboratory data from the time it is first

generated, through entry into, and use within a computer database system, and presentation as tables,

charts, graphs, maps and cross-sections. Three levels of quality assurance/quality control (QA/QC)

review are incorporated into the DMS as follow; (i) on raw data prior to input to computer database files,

(ii) on the computer database files, as a check on input procedures, and (iii) on computer database output,

to check that the database was used corr^tly to prepare the output. The Quality Assurance Officer is

responsible for the Level 1 QA/QC review of all non-laboratory field data. The Data Management

Coordinator is responsible for QA/QC review of all laboratory data and all internal data base and output

QA/QC reviews.

Site-specific field and laboratory procedures to be used at the Gallup's Quarry site are incorporated into

the DMS by reference to the specifications outlined in the Field Sampling Plan (FSP). Project-specific

QA/QC procedures to be used are incorporated into the DMS by reference to the specifications outlined

in the Quality Assurance Project Plan (QAPP).

The DMS will manage the following types of data:

• Data compiled for the Gallup's Quarry site prior to the RI/FS, including chemical testing

results for soil, groundwater, and surface water, and information from subsurface

exploration logs and monitoring well construction reports.

• Data compiled during the RI/FS, including: chemical testing results for samples of soil,

groundwater, surface water, sediments, air and soil gases; subsurface exploration logs

(including geophysical surveys and logs);, monitoring well construction details; and

monitoring and sampling procedures.

The DMS will be expanded to include additional types of data based on project needs.

SMP-23; 08/29/94

6.2 DATA ORGANIZATION, REDUCTION, AND QA/QC PROCEDURES

The DMS provides a structure for handling site data using the following steps:

• "Raw" data will be compiled in "working files", including the existing site data, and the

field and laboratory reports prepared while performing the RI/FS Work Plan. Generally,

these will be paper (aka, hard copy) files.

• A Level 1 QA/QC review process will be performed on the working files until these are

considered complete and correct. After the Level 1 QA/QC procedure is performed, the

files will become hard copy "record files". In some cases (e.g., for laboratory chemical

testing data) the hard copy record files will be transmitted to ESE on magnetic disk or

by fax modem, after the Level 1 QA/QC review has been completed. This will allow

direct data input to the computer database system.

For data existing prior to the RI/FS, the Level 1 QA/QC review of working files will include

interpreting and reducing the data to prepare them for input to the computer database system.

The existing data will be assumed to be essentially correct at the time they are obtained by ESE

and will not be edited prior to input, except in the case of clear and obvious errors such as use

of incorrect units or typographical errors.

For data obtained during the RI/FS, the Level 1 QA/QC procedure will include a review of all

data points in field and laboratory reports for completeness, indications of aberrations, adherence

to and interferences with specified procedures, and reasonability. Edits will be made, where

needed, to transform the working files into record files which are considered complete and

correct. Examples of such edits are correcting a mis-typed well identification number on a

laboratory report, refining field soil descriptions based on an in-house review of jar samples of

the soil, or "flagging" a data point because of an aberration (e.g., intended detection limit not

achieved due to high matrix interference).

• Record file data will be input to the working files of the computer database system, either

by manual data entry or electronic file transfer, depending on the type of record file.

• A Level 2 QA/QC review will be performed for the working files of the computer

database system, to establish the integrity of the data input procedures. This review will

be done by comparing selected data points in the electronic database files with the record

files, and making edits as needed, until the database files and the record files are

SMP - 24; 08/29/94

considered identical. When they are considered identical, the computer database system

files will be considered database system record files. Electronic memory backup files

will be made of the computer database system record files. Through the course of the

RI/FS, updated memory backup files will be made when the database system record files

are added to or otherwise modified.

• Data from the database system record files will be manipulated (i.e., accessed and

"used") using query programs. The query programs will allow data to be analyzed and

summarized for presentation purposes (e.g., as tables and maps).

• A Level 3 QA/QC review will be performed on output from the query programs, to

assure that the programs are correctly written and used. This will be done by manually

calculating select portions of the output and comparing these with the computer generated

data. After any required edits to the programs are made and checked, the database

system output will be prepared as presentation quality or interpretation quality

documents. At this stage the output documents will be considered correct. [Note:

Interpretation quality output are for the use of project scientists and engineers during

their work in interpreting the RI/FS data, and are not necessarily in presentation quality

format suitable for inclusion in final documents (e.g., with respect to column order on

tables, or notes on figures).]

6.3 COMPUTER DATABASE SYSTEM

A computerized database management system has been designed by ESE specifically to manage and

organize a large amount of sampling and analytical data. The system operates in a user-ready format

using a commercially available programming language/software package (Paradox*).

This data management system is intended to serve as the database for data generated in past and ongoing

phases of the project. The data management system is designed to provide the technical project staff with

a vehicle to sort, arrange, and thereby analyze data with speed and efficiency, while allowing user-

specified reporting capabilities. Output from the program may be generated for direct printing and

plotting, or in file form (ASCII or Symphony* spreadsheet formats) for use by other software. Data will

be provided to EPA in a format suitable to their oversight contractor, for use in developing the risk

assessments.

SMP-25; 08/29/94

Analytical data, and sampling and monitoring well data are either entered by importing a pre-existing file

or by entering data from the keyboard within the program. The program processes both numeric and

alphanumeric fields and allows descriptive text to be entered.

The Paradox* database completes a quality assurance check of the data by cross referencing the data

being imported against data already in the system. Additional cross referencing occurs during querying

applications, construction of tables, and generation of reports, at which time duplication, spelling

mismatches, and other errors are identified and displayed.

Organization of data in tabular form is especially useful as a decision-making tool during a site

investigation. By allowing the user to select criteria for construction of each table, the data management

system facilitates generation of unique data tables from which to analyze various problems and scenarios.

Data may be sorted by sample ID, analyte or groups of analytes, dates, or any other identifier which

might be added to the data field. Positive hit tables can be generated which greatly simplify presentation

and review of large data sets. In addition, die Paradox* database also has built-in analysis capabilities

including statistics and graphics.

The fo.mat used to review and arrange data exists in a menu-driven mode for on-screen analysis. Pre

written scripts have been designed to incorporate the data into various pre-built tables and lists, based on

sample-specific criteria such as sampling date, sample location, sample matrix, analyte type, analyte

concentration, and detection limits.

Output from the system can be generated in a variety of formats including Paradox* text and graphical

printouts, spreadsheet form (e.g., Symphony*), or ASCII file form. The ASCII file output can be

utilized directly by other software to produce contour maps and graphs, or to serve as input for

analytical/numerical models.

Final reports may include graphic representation of physical and chemical data using a combination of

contouring, graphing, and drafting software (e.g., Surfer* Grapher*, and Autocad Release 13*).

6.4 DATA OUTPUT AND PRESENTATION

The Data Report will present summaries of all validated data collected during the Phase 1A field

investigations. ESE will use its analytical data management database to generate summary tables for the

Data Report. The database allows easy and quick manipulation of data. Table A-2 provides an example

SMP-26; 08/29/94

of a positive hit data table. The positive hit table is generated by first selecting any analyte detected in

any sample and then developing a table, using that list of analytes, for all samples of interest.

SMP-27; 08/29/94

7.0 MONITORING AND REPORTING MEASURES

7.1 SITE AIR MONITORING

Air monitoring will be performed at the Gallup's Quarry Superfund Site to assist in protecting the health

and safety of site workers and the surrounding community. During the initial site reconnaissance air

sampling and analysis will be performed at the three known disposal areas and three predominantly

downwind property boundary locations, for VOCs and particulates. The predominant downwind

directions were determined by using annual wind rose data collected at Bradley International Airport in

Windsor Locks, Connecticut. The air sampling locations and wind rose data are shown on Figure A-18.

During intrusive field activities continuous air monitoring will be performed in the workers breathing

zones using a PID for total VOCs, and a RAM-1 for particulates. Draeger tubes will be used to monitor

for Benzene, Carbon Tetrachloride, Chloroform, and Ethylene Dichloride and 1,1 DCE vapors detected

in the breathing zone when a sustained reading of 1 ppm or greater is recorded in the workers breathing

zone using a PID. When sustained readings of total VOCs exceed 1 ppm in the workers breathing zone,

continuous monitoring for VOCs and particulates will be performed at the perimeter of the exclusion

zone. If total VOC concentrations exceed background readings at the downwind edge of the exclusion

zones during any intrusive activities, monitoring of the actual downwind property boundary locations

for VOCs and particulates will be performed at a minimum of twice a day until exclusion zone boundary

readings return to normal. Wind direction, wind speed, temperature, and barometric pressure will be

monitored at the on-site meteorological station.

Action levels and responses are summarized in the HSP. Sections 3.2.3 and 3.2.4 of the SMP should

be thoroughly read for information concerning appropriate actions to be taken during a chemical release.

7.2 FINANCIAL MONITORING

The Settling Parties will provide a summary of all costs incurred by the Settling Parties in performing

die work under the Administrative Order semi-annually to the USEPA.

In order to investigate suspected environmental contamination at this Site, the United States Environmental Protection Agency is requiring that certain surveying and environmental monitoring activities take place. Due to the proximity of your property to this Site, some of these investigatory activities may have to be undertaken on your property. The purpose of these activities is to assure that your property has not been adversely affected by contamination which might emanate from the Site. Additionally, if these activities show that your property has been affected, these activities will help us determine what steps should be taken to remedy the situation. In short, these activities are being done for your benefit.

The Gallup's Quarry PRP Group is a group of companies who, though they do not believe they are responsible for the conditions at the Gallup's Quarry Site, have jo'intly agreed to investigate the existence of and or extent of contamination at this Site. They have, accordingly, entered into a consent order (a form of an administrative order) with the United States Environmental Protection Agency that requires them to undertake certain investigatory activities including surveying and monjtoring at your property.

By signing this Agreement, you will permit the Gallup's Quarry PRP Group, its consultants, contractors, subcontractors, agents, and other authorized representatives, and the United States Environmental Protection Agency and its designated coordinators, agents, employees, contractors, consultants and other authorized representatives to enter your property for the purposes stated herein, subject to the conditions set forth below:

1. Access will be limited to the outdoor areas of your property, between the hours of 8 A.M. and 5 P.M., on weekdays that are not recognized holidays.

.2. The activities that may be conducted will be limited to:

(a) Surveying, within the usual meaning of that term. This activity may involve the placement of stakes and other surveyors markers. Some will be temporary, and a few will be permanent. Permanent markers will be small, just like markers used by surveyors who work for homeowners to locate property boundaries.

(b) Dri l l ine monitoring wel ls . A monitoring well, which is just a small water well, might have to be driUed on your property. This will involve conventional well-drilling equipment.

(c) Taking Soil Sample^ This will involve excavating small amounts of soil from a few places, which wiii be done by either a hand or motorized auger or other digging equipment.

(d) Surface and Subsurface fnvestigation. Various techniques will be used to investigate the site including surface water and sedimentation sampling and geophysical and soil gas surveying. The sou" gas survey involves inserting and removing an approximately 3/4 inch rod into the soil to extract soil vapors which can then be analyzed. The other sampling and surveying techniques do not involve any intrusive work.

3. Every reasonable effort will be made to minimize disruption of your property and your daily life. Some noise or dust are, however, to be expected because of these activities, and the location of digging or drilling may have to be located in a particular spot because of technical requirements relating to the type of information we are required to obtain.

4. At the end of each day's work, we will leave your property in as clean a condition as possible. Any areas of unavoidably disturbed or excavated condition will be shown to you or clearly marked to alert you to their condition.

5. At the completion of the work, your property will be restored to substantially the same condition that existed prior to the work. Any holes will be filled and regraded.

6. Access will be permitted under the terms of this agreement for the length of time necessary for completion of the activities covered by it, in accordance with the requirements of the United States Environmental Protection Agency.

Should you be willing to grant the requested access, please sign this document (if the property is jointly owned or otherwise co-owned, both owners must sign) and return it to the GaJlup's Quarry PR? Group within 10 days of your receipt of this form in the stamped, pre-addressed, envelope provided. If you have any questions, you may call the United States Environmental Protection Agency's Remedial Project Manager. Ms. Leslie McVickar at (617) 593-9689 or the Project Coordinator for the Gallup's Quarry PRP Group, Mr. William Kay. Jr. at 659-4248.

1.0 INTRODUCTION

This Quality Assurance Project Plan (QAPP) is one of severaJ site specific plans developed by Haley &

Aldrich, Inc. and finalized by Environmental Science & Engineering, Inc. (ESE) for the Settling Parties

to establish procedures to be followed by personnel during implementation of the Remedial

Investigation/Feasibility Study (RI/FS) Work Plan. This QAPP constitutes one portion of the Project

Operation Plan (POP), which also includes, the Site Management Plan (SMP), Field Sampling Plan

(FSP), Site Specific Health and Safety Plan (HSP), and the Community Relations Support Plan. The

QAPP is based in-part on information contained in the Statement of Work (SOW), dated 7 September

1993 contained in the Administrative Order of Consent dated 8 September 1993 as agreed to by the

United States Environmental Protection Agency (EPA) and the Settling Parties. The QAPP is subject to

EPA's review and revisions prior to the implementation of the field work at the Gallup's Quarry site.

The QAPP provides the process, procedures and criteria for ensuring that the Data Quality Objectives

(DQO's) of the RI/FS are met.

QAPP-5; 08/29/94

2.0 PROJECT DESCRIPTION

The Gallup's Quarry property occupies an approximate 22-acre site located in the town of Plainfield,

Windham County, Connecticut, as shown on Figure B - l , Project Locus. The site borders Route 12 and

private residences to the east; railroad tracks abut the site to the west; a power transmission line, Mill

Brook and wetlands are north of the site; and Tarbox Road borders the site to the south.

The site topography is erratic due to previous quarry activities, but generally slopes toward the west as

shown on the Site Plan included in this QAPP, as Figure B-2.

The Gallup's Quarry Remedial Investigation will define the sources, nature, extent, and distribution of

contaminants released during the former disposal operations at the property. To accomplish these tasks,

the investigation will utilize a variety of intrusive and non-intrusive techniques. Intrusive techniques will

include the sampling and analysis of soil vapor in the vadose zone, unsaturated and saturated overburden

soils, sediments, surface water and groundwater. Non-intrusive techniques will include air quality

monitoring, and the use of electromagnetic survey instruments (EM31, MAG), and ground penetrating

radar (GPR) to assess the presence/absence of buried metal objects and help identify the presence of

residual contaminated soil.

The investigation will include each analytical level as defined by the Data Quality Objectives for Remedial

Response, EPA/540/G-87/003, March 1987.

LEVEL I - Portable field monitoring equipment (i.e. OVA-128GC) for site worker Health

and Safety purposes and presence/absence determinations of volatiles organic

compounds (VOCS).

LEVEL II- Headspace analysis of overburden soils, vadose zone soil gas, and perched

groundwater using a portable gas chromatograph (GC) and field geophysical

analysis systems.

LEVEL III- Micro Well metals screening parameters and wet chemistry parameters using EPA

Methods as published by "Test Methods For Evaluating Solid Waste", SW-846,

1986 with updates, for additional site characterization.

QAPP-6; 08/29/94

LEVEL IV/V- Target compound list (TCL), target analyte list (TAL), using Contract Laboratory

Program (CLP) Statement of Work (SOW) OLM01.8 and ILM03.0 methodology'

and reporting requirements. Appendix IX analyses by CLP and SW-846

Methods. Low level TCL volatiles analysis by EPA Method 524.2 with CLP

SOW reporting.

Analytical levels will be utilized in a phased approach. Initial site surveys will employ primarily Level

I and II analytical protocols. Nature and extent determinations will utilize Level II, III and IV/V

analytical protocols. Level III, IV and V data will be presented in formats suitable for validation by an

independent professional. The validation will utilize EPA Region I guidance documents to qualify data

for inclusion within a site specific risk assessment (RA) database. The RA database will be compiled to

provide sufficient information to determine the risks to human health and the environment from the

contamination delineated at the site by the investigation. The RA findings will provide direction for the

development of remediation alternatives suitable to reduce the determined risks to below acceptable

thresholds.

This Quality Assurance Project Plan provides the standard operating procedures, analytical methodologies

and data quality objectives which will enable the development of a RA database of validated analytical

results to direct the remediation of the Gallup's Quarry Superfund Site.
