1. INTRODUCTION Subject Property This report has been prepared to present the design methodology and calculations for the management of stormwater runoff associated with the proposed project. The subject property is known as Block 233, Lots 2, 7 & 12 as shown on the City of Plainfield tax maps. The property has a total area of approximately 5.03 acres, is located fronting onto West Front Street to the west, and is bordered by Plainfield Avenue and commercial and residential properties to the north, Conrail mainline to the east and Waynewood Park and commercial property to the south in the City of Plainfield, Union County, New Jersey (see Appendix A for a site location map). The site is located in the Block 233 Redevelopment Plan, Marino’s Tract, Redevelopment Area and has been previously disturbed, graded and filled, with existing warehouse and car dealership buildings, asphalt parking areas, lawn and wooded areas. No wetlands are present on-site and no water-courses pass through the site. Proposed Development The proposed development will consist of a mixed used development with approximately 16,500 square feet of commercial space on West Front Street and a residential apartment complex with 316 units above the commercial space extending to the rear of the property. A management office for the apartment component of the development is accessed from Plainfield Avenue. Additional site improvements include pavement parking areas, concrete sidewalks, and utility infrastructure, as well as grading, landscaping and lawn areas that are associated with the proposed development of the site. Stormwater Design The design of the stormwater collection and management system have been directed by the following guidelines:

1. New Jersey Department of Environmental Protection (NJDEP) Stormwater Management Rules (N.J.A.C. 7:8)

2. New Jersey Stormwater Best Management Practices (BMP) Manual, April 2004, last revised 2020.

3. Standards for Soil Erosion and Sediment Control in New Jersey, January 2004. 4. New Jersey Residential Site Improvement Standards (RSIS), (N.J.A.C. 5:21). 5. USDA NRCS, Web Soil Survey for Plainfield, Union County 6. Urban Hydrology for Small Watersheds, Tr-55 Manual, June 1986. 7.

Stormwater Analysis

The proposed development will disturb greater than 1 acre of land, therefore, is definted as a

“Major Development”. As such, this report and the proposed stormwater management plan have

been prepared in accordance with the above referenced guidelines.

The existing drainage conditions were analyzed under current on-site conditions for the subject

property. The existing runoff is discharged into existing stormwater drainage systems located in

adjacent roadways.

The proposed drainage conditions were analyzed to determine the flows generated from the

proposed site improvements.

The following sections will address the existing conditions of the site and the impact of the

proposed development on the existing drainage conditions.

Stormwater Runoff Quantity Requirements

The proposed stormwater management plan reduces the proposed development peak runoff rates

for the 2, 10 and 100-year storm events by the required respective 50, 75 ad 80 percent

reductions of the previously existing peak runoff rates. This is achieved through the use of an

underground stormwater detention BMP.

The storm water analysis was computed utilizing the Soil Conservation Service (SCS) Technical

Release 55 (TR-55) “Urban Hydrology for Small Watersheds,” revised June 1986, method for

the 2, 10, and 100-year storm frequencies. The rainfall distribution is based upon the SCS Type

III 24-hour storm. Time of concentration computations were based on industry minimum times

of 10 minutes per the New Jersey Residential Site Improvement Standards (RSIS) for time of

concentrations below 10 minutes.

Stormwater Quality Requirements

Pursuant to the NJDEP Stormwater Runoff Quality Standards, the proposed stormwater runoff

from the new impervious surface areas (not including rooftops) will be treated for 50% total

suspended solids (TSS) removal by a NJDEP certified manufactured treatment device (MTD) to

be located within the parking area prior to be routed into the underground detention system.

With the rooftop area considered clean by NJDEP standards, mingling with the pavement and

concrete areas, and is a greater area than the other two combined, only 50% TSS removal is

required.

Groundwater Recharge

This project is exempt from the NJDEP’s Groundwater Recharge requirement since the site is

located within an “urban redevelopment area”, as shown on the NJDEP Policy Map of State

Development and Redevelopment Plan.

Stormwater Management Maintenance Plan

In accordance with the municipal ordinance and regulations referenced within, a maintenance

plan for the proposed stormwater management measures is provided in this report.

Soil Erosion and Sediment Control

The proposed development plans to disturb greater than 5,000 square feet of land, therefore, a

Soil Erosion and Sediment Control (SESC) Plan has been developed and will be submitted for

certification to the Somerset-Union Soil Conservation District (SCD), pursuant to the SESC Act,

Chapter 251, P.L. 1975 as amended (N.J.S.A. 4:24-39 et. seq.). The proposed SESC measures

have been designed in accordance with the Standards for SESC in New Jersey. SESC Plan

Certification approval will be provided to the City of Plainfield prior to the commencement of

earthwork.

2. METHODOLOGY

Computations were performed Hydraflow Hydrographs Extension for Autodesk Civil 3D.

According To the United States Department of Agriculture (USDA), Natural Resources

Conservation Service, Web Soil Survey (WSS), the soil survey indicated the subject property

consists of an Urban Land (UR) and Birdsboro-Urban Land complex (BhpBr) soil classification.

UR does not have a corresponding hydrologic soil group classification while the BhpBr has a B

rating. To be conservative, a hydrologic soil group grading of ‘D’ was designated to be used in

the control of stormwater runoff generated from the proposed development since over 90% of the

subject property is located in the UR soil classification. See Appendix B for the Soil Map.

One (1) underground detention systems were incorporated into the proposed stormwater

management system to demonstrate flow reduction under the 2-, 10- and 100-year storm events

of 50%, 75% ad 80% of existing flow, respectively.

Under the existing conditions, a drainage area map was developed and used to determine and

demonstrate existing stormwater runoff patterns from the subject property. Similarly, a proposed

conditions drainage area map was created to illustrate proposed stormwater runoff generated as a

result of developing the site as shown on the design plans.

The existing and proposed stormwater runoff rates were compared for the 2-, 10- and 100-year

storm events. A comparison of the existing and proposed flows was performed and shown to

comply with the requirements of applicable review agencies. One (1) underground detention

systems with an outlet control structure was designed to achieve the required reductions.

6

A SiteSaver Stormwater Treatment System water quality unit was incorporated into the design

for the underground detention facility.

3. STORMWATER ANALYSIS

Analysis Parameters

The 2-, 10-, and 100-year storm events were modeled to determine the overall stormwater runoff

under the existing and proposed conditions to the existing drainage system.

Rainfall Intensity

Precipitation frequency rainfall estimates for the subject property were obtained from NOAA,

National Weather Service data.

Existing Conditions

The existing watershed area was delineated as shown on the attached Existing Drainage Area

Maps provided in Appendix F and consists of three (3) drainage areas. The point of analysis for

each drainage area is an existing inlet in the adjacent roadways.

Drainage Area 1 has runoff directed to the south towards Waynewood Park and has a total

drainage area of 0.67 acres. No drainage system exists in Waynewood Park until the intersection

of Waynewood Park with West Front Street approximately 200 feet to the west. The drainage

area consists of buildings, asphalt pavement, concrete, lawns and wooded areas.

Drainage Area 2 has runoff directed from the Contrail property located to the east across the

subject property to West Front Street in the west and has a total drainage area of 4.80 acres. The

drainage area consists of buildings, asphalt pavement, concrete, lawns and wooded areas.

Drainage Area 3 has runoff directed to the north towards Plainfield Avenue and has a total

drainage area of 0.28 acres. The drainage area consists of a wooded area.

No stormwater management facilities or pipe conveyance system exists in any drainage area.

The soils within each existing drainage area are urban and have been classified as hydrologic soil

group D (see Appendix B).

The HydraFlow Hydrographs program was used to determine the existing peak flows for

Drainage Areas 1 and 2 used in the analysis. Drainage Area 3 was not developed. These flows

are summarized in Table 1.

Appendix C provides hydrographs for the existing conditions area.

7

Proposed Conditions

The proposed watershed area was delineated as shown on the attached Proposed Drainage Area

Maps provided in Appendix F and consists of four (4) drainage area. The point of analysis for

each drainage area is an existing inlet in the adjacent roadways. The total proposed drainage

area is 5.75 AC. The drainage area consists of impervious building, driveways and parking

areas, landscaping and lawn areas.

Under the proposed condition, stormwater runoff generated from the proposed building, parking

area, concrete sidewalks and landscape areas is directed to area inlets and conveyed to the

proposed underground detention facility via catch basins and storm pipes having a minimum size

of 12”. The stormwater conveyance system consists of a two conveyance runs directing surface

runoff to the underground detention facility. Rooftop leaders were connected directly to the

underground detention system.

The HydraFlow Hydrographs program was used to determine the proposed unrouted peak flows

for Drainage Areas 1, 2 and 3 used in the analysis. Drainage Area 4 was not developed and is

the same as the existing conditions Drainage Area 3. These flows are summarized in Table 1.

The HydraFlow Hydrographs program was used to determine the proposed routed peak flows

for each drainage area. These flows are summarized in Table 1.

Appendix C provides hydrographs for the proposed conditions area.

As shown in Table 1, the peak flow for the 2-, 10- and 100-year storm events have been reduced

to 43%, 65% and 78% respectively when compared with the reduction requirements of 50%,

75% and 80%.

8

It should be noted that existing Drainage Areas 1 and 2 where compared to proposed Drainages

Areas 1, 2 and 3, since existing Drainage Area 3 is under changed and the same as proposed

Drainage Area 4.

The proposed underground detention system consists of 4 foot by 4 foot concrete chambers, 109

feet in length with 20 barrels and headers. Discharge is controlled by an outlet control structure

which has a 6 inch diameter orifice and a rectangular weir with a 2 foot long crest.

4. WATER QUALITY

Water Quality Design Storm

Stormwater runoff generated from the rooftop is assumed to be cleaned under NJDEP rules and

when intermingled with the asphalt parking area runoff, only a 50% TSS removal unit is

required.

The water quality design storm is 1.36 cfs. A SiteSaver Stormwater Treatment System by

StormTrap is proposed with a maximum water quality storm flow of 4.32 cfs.

See Appendix D for Water Quality Calculations.

Manufactured Treatment Device

Pursuant to Chapter 9.6 of the NJ Stormwater BMP Manual:

The TSS removal rate of the MTD must be certified by the NJDEP Division of Science,

Research & Technology (DSRT).

The MTD is not required for storage or flow rate attenuation, therefore, design is based

on peak flow rate.

To achieve its assigned TSS removal rate, the MTD must be designed to treat the runoff

generated by the stormwater quality design storm.

The MTD must be able to safely overflow or bypass flows of excess of stormwater

quality design storm.

The MTD will be subsurface, therefore, must be designed for HS-20 traffic loading.

The MTD will be an on-line system receiving upstream runoff from all storms, providing

runoff treatment for stormwater quality design storm and conveying the runoff from

larger storms through an overflow.

A maintenance plan for the MTD is required.

9

5. PIPE CALCULATIONS

A combination of PVC pipes for roof leaders and RCP for conveyance systems are utilized

throughout the development. The minimum slope is 0.5% and pipe sizes include 6” in diameter

for roof leaders and 12” for conveyance piping. Trench drains are provided at the bottom of

driveway slopes.

See Appendix E for pipe conveyance calculations.

6. SOIL EROSION AND SEDIMENT CONTROL

The proposed demolition and construction activities will disturb greater than 5,000 square feet of

land, therefore, the following soil erosion and sediment control measures will be incorporated

into the design plans.

Stabilized Construction Access (SCA)

SCAs are proposed for the site accesses along South Second Street. The SCAs will reduce the

tracking of sediment onto the public roadway and mitigate the potential for sediment laden

runoff to enter the municipal stormwater and adjacent waterways. All SCAs should be installed

and maintenance in accordance with the Somerset-Union SCD and SESC plan.

Silt Fence Perimeter Protection

Silt Fence (SF) perimeter controls shall be installed along the down gradient edge of the active

construction site. Per the SESC standard, the fence posts shall be construction of a hardwood

with minimum diameter of 1 ½ inches, spaced a minimum of 8-feet apart and extend a minimum

of 2 feet above and below grade. The geotextile fabric hall be buried at least 6-inches below

grade and extend at least 2 feet above grade. Metal fasteners and high strength reinforcement

material shall be used to fasten the geotextile fabric to the posts in a manner that resists tearing

away from the post. The fabric shall incorporate a drawstring in the top portion of the fence for

added. The sediment barrier will intercept and detain small amounts of sediment from being

discharged off-site. The silt fence perimeter controls shall be maintained in accordance with the

SESC standards.

Stockpile Controls

Stockpile controls shall be placed around all stockpiles of fine materials that are inactive. See

SESC notes. Stockpiles of suspect contaminated material should be placed on plastic sheeting

and contained such that no potentially contaminated runoff can infiltrate the groundwater or flow

off site.

10

Steep Slope Protection

Disturbed slopes shall be stabilized as soon as possible and slopes greater than 2:1 require steep

slope stabilization per SCD. Stabilizations methods include temporary/permanent seeding,

mulch, blankets and/or rolled products.

Inlet Protection

Existing and proposed inlets shall be protected per the SESC standards, which may include filter

fabric with perimeter controls and/or inlet protection bags. The installation and maintenance of

the inlet protection measures shall be in accordance with the SESC standards.

Dust Control

During demolition and construction activities, especially during dry conditions, a water truck

shall be present on-site to mitigate the generation and release of fugitive dust and gaseous air

pollutants. Areas of disturbed sediment and heavy traffic should be wetted regularly. Dust

control shall be maintained, during demolition activities. The application of dust control

polymers and/or perimeter screen fencing may be warranted depending on site conditions.

Concrete Truck Washout Areas

If on-site washout of the concrete trucks is proposed, a prefabricated washout container shall be

delivered to the site. Per the SESC standards, the washout area shall not be located adjacent to

identified surface drainage features or wetland areas. The washout container should be cleaned

or changed when it is filled to 75% capacity.

Hazardous Material Storage and Spill Protection

All hazardous materials shall be properly stored and maintenance with appropriate spill

protection measures.

Somerset-Union Soil Conservation District Soil Erosion and Sediment Control Notes

1. All Soil Erosion and Sediment Control practices shall be installed prior to any major soil

disturbances, or in their proper sequence and maintained until permanent protection is

established.

2. Any Disturbed areas that will be left exposed more than 30 Days and not subject to

construction traffic, will immediately receive a temporary seeding. If the season prevents the

establishment of a temporary cover, the disturbed areas will be mulched with a straw, or

equivalent material, at a rate of two (2) tons per acre, according to NJ State Standards.

3. Permanent Vegetation shall be seeded or sodded on all exposed areas within ten (10) days

after final grading. Mulch will be used for protection until seeding is established.

11

4. All work shall be done in accordance with the NJ State Standards for Soil Erosion and

Sediment Control in New Jersey.

5. A sub-base course will be applied immediately following rough grading and installation of

improvements in order to stabilize streets, roads, driveways and parking areas. In areas

where no utilities are present, the sub-base shall be installed within 15 days or preliminary

grading.

6. Immediately following initial disturbance or rough grading all critical areas subject to erosion

(i.e.: steep slopes, roadway embankments) will receive a temporary seeding in combination

with straw mulch or a suitable equivalent, at a rate of two (2) tons per acre, according to the

NJ State Standards.

7. Any steep slopes receiving pipeline installation will be backfilled and stabilized daily, as the

installation proceeds (i.e.: slopes greater than 3:1).

8. Traffic control Standards require the installation of a 50’x30’x6’’pad of 1 1/2” or 2” stone, at

all construction driveways, immediately after initial site disturbance.

9. The Somerset-Union Soil Conservation District shall be notified in writing 48 hours in

advance of any land disturbing activity.

10. At the time when the site preparation for permanent vegetative stabilization is going to be

accomplished, any soil that will not provide a suitable environment to support adequate

vegetative ground cover, shall be removed or treated in such a way that will permanently

adjust the soil conditions and render it suitable for vegetative ground cover. If the removal or

treatment of the soil will not provide suitable conditions, non-vegetative means of permanent

ground stabilization will have to be employed.

11. In that NJSA 4:24-39 et seq., requires that no Certificate of Occupancy be issued before the

provisions the Certified Plan for Soil Erosion and Sediment Control have been complied with

for permanent measures, all site work for site plans and all work around individual lots in

subdivisions, will have to be completed prior to the District issuing a Report of Compliance

for the issuance of a Certificate of Occupancy by the Municipality.

12. Conduit Outlet Protection must be installed at all required outfalls prior to the drainage

system becoming operational.

13. Any changes to the Certified Soil Erosion and Sediment Control Plan will require the

submission of revised Soil Erosion and Sediment Control Plans to the District for re-

12

certification. The revised plans must meet all NJ State Soil Erosion & Sediment Control

Standards.

14. The Somerset-Union Soil Conservation District shall be notified of any changes in

ownership.

15. Mulching to the NJ Standards is required for obtaining a Conditional Report of Compliance.

Conditionals are only issued when the season prohibits seeding.

16. Contractor is responsible for keeping all adjacent roads clean during life of construction

project.

17. The developer shall be responsible for remediating any erosion or sediment problems that

arise as a result of ongoing construction at the request of the Somerset-Union Soil

Conservation District.

18. Hydro seeding is a two- step process. The first step includes seed, fertilizer, lime, etc., along

with minimal amounts of mulch to promote consistency, good seed to soil contact, and give

a visual indication of coverage. Upon completion of seeding operation, hydro-mulch should

be applied at a rate of 1500 lbs. per acre in second step. The use of hydro-mulch, as opposed

to straw, is limited to optimum seeding dates as listed in the NJ Standards.

7. STORMWATER MANAGEMENT MAINTENANCE PLAN This stormwater maintenance plan has been prepared in accordance with the City of Plainfield's

municipal, Stormwater Management ordinance and applicable chapters of the NJDEP Stormwater BMP

Manual. The site's stormwater management measures shall be maintained in accordance with the

NJDEP Stormwater Management BMP Manual and the Standards for SESC in New Jersey, and any

manufacturer's specifications.

Underground Stormwater Detention Chambers

To meet the NJDEP Stormwater Management Quantity Requirements, an underground

stormwater detention systerm has been designed for the site.

Inspection Notes

During the first service year a visual inspection should e completed during and after each

major rainfall event, in addition to semi-annually, to establish a pattern of sediment and

debris build up.

13

Second year plus; establish an annual inspection frequency based on the information

collected during the first year. At a minimum an inspection should be performed semi-

annually.

Inspect inspection ports, inflow/outflow points, including inlet/manhole pipes and

discharge area.

Identify and report maintenance required, including sediment and debris accumulation,

system backing up, and flow rate change.

Maintenance Procedures

Conform to all local, state and federal regulations.

Determine if maintenance is required.

Use a vacuum pump truck to evacuate debris from the inflow and outflow points.

Flush the system with clean water forcing debris from the system. Take care to avoid

extreme direct water pressure when flushing the system.

Manufactured Treatment Device Maintenance Notes

Sufficient and suitable access must be provided for each chamber in the device for

inspection and maintenance activities; including adequate clearance from structures to

allow for placement and operation of maintenance equipment.

The MTDs should be inspected and maintained in accordance with the manufacturer's

instructions and/or recommendations and any maintenance requirements associated with

the MTD's certification by NJDEP.

The MTDs shall be inspected for clogging and excessive debris and sediment

accumulation at least four times annually as well as after every storm exceeding 1 inch of

rainfall.

Disposal of debris, trash, sediment, and other waste material should be done at suitable

disposal/recycling sites and in compliance with all applicable local, state and federal

waste regulations.

Vegetation

The prescribed MTDs will not utilize vegetation.

Structural Components

All structural components must be inspected for cracking, subsidence, spalling, erosion and

deterioration at least annually and per manufacturer's specifications.

Other

Maintenance plan must indicate the maximum level of oil, sediment, and debris

accumulation allowed before removal is required.

14

Removal levels should be monitored during device inspections to help determine the need

for removal and other device maintenance.

Prescribed StormTrap SiteSaver Maintenance Notes

Routine inspection and maintenance program should be established for each unit based

on:

o The volume of load of the contaminants of concern,

o Frequency of releases of contaminant at the facility, and

o The nature of the area being drained.

Inspections can occur from the surface, eliminating the need to enter the systems to

determine when cleanout should be performed.

Quarterly inspection is recommended for the first year to develop an appropriate schedule

of maintenance, typically the inspection schedule for subsequent years is semi-annual.

Refer to Appendix G StormTrap SiteSaver NJDEP Certification.

Debris and Sediment Disposal

All removed debris and sediment shall be disposed in a legal manner in accordance with all

applicable local, county and state agencies having jurisdiction.

must be maintained for at least five (5) years by the responsible party. Copies of these

documents must be submitted to the Township Engineer by April 1st every five (5) years. This

should include all receipts for materials and labor purchased. Manufacturer's documents,

including warranty information, shall also be retained.

8. CONCLUSIONS

The proposed development of Block 233, Lots 2, 7 & 12 will utilize one (1) proposed

underground detention facility to accommodate runoff generated from development of the

subject property. Additional drainage improvements, including proposed structural water quality

device, area inlets and conveyance piping, have been used to satisfy design parameters and

requirements set forth in the stormwater management rules and regulations.

The development will reduce peak flow from the site for the 2-year, 10-year and 100-year storm

at the point of analysis under the proposed conditions.

Water quality will be addressed with the use of a StormTrap SiteSaver Stormwater Treatment

System 50% TSS device.

Warning: Soil Map may not be valid at this scale.

Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale.

Please rely on the bar scale on each map sheet for map measurements.

Source of Map: Natural Resources Conservation ServiceWeb Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857)

Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

This product is generated from the USDA-NRCS certified data as of the version date(s) listed below.

Soil Survey Area: Union County, New JerseySurvey Area Data: Version 14, Jun 1, 2020

Soil map units are labeled (as space allows) for map scales 1:50,000 or larger.

Date(s) aerial images were photographed: Jul 26, 2019—Jul 31, 2019

The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Description

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission.

If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Appendix D: Water Quality Calculations

Water Quality Calculations

The rooftop area intermingles with the impervious area runoff and the Stormwater Quality Design is

calculated using the Rational Method: Q = CIA

Where:

Proposed Pervious Areas = 0.58 acres

Proposed Rooftop Area = 1.99 acres

Proposed Impervious Areas = 2.19 acres

Non-source of TTS = 0.58 + 1.99 = 2.57 acres > Source of TSS = 2.19 acres

Therefore, only 50% TSS removal required for the TS source.

Re: MTD Lab Certification

StormTrap SiteSaver® - 4 Hydrodynamic Separator (STSS-4) by FreshCreek Technologies, Inc.

Offline or Online Installation

TSS Removal Rate 50%

Dear Mr. Fajman:

The Stormwater Management rules under N.J.A.C. 7:8-5.5(b) and 5.7 (c) allow the use of manufactured

treatment devices (MTDs) for compliance with the design and performance standards at N.J.A.C. 7:8-5 if

the pollutant removal rates have been verified by the New Jersey Corporation for Advanced Technology

(NJCAT) and have been certified by the New Jersey Department of Environmental Protection (NJDEP).

FreshCreek Technologies, Inc. has requested an MTD Laboratory Certification for the StormTrap

SiteSaver® - 4 Hydrodynamic Separator.

The projects falls under the “Procedure for Obtaining Verification of a Stormwater Manufactured

Treatment Device from New Jersey Corporation for Advance Technology” dated January 25, 2013. The

applicable protocol is the “New Jersey Laboratory Testing Protocol to Assess Total Suspended Solids

Removal by a Hydrodynamic Sedimentation Manufactured Treatment Device” dated January 25, 2013.

NJCAT verification documents submitted to the NJDEP indicate that the requirements of the

aforementioned protocol have been met or exceeded. The NJCAT letter also included a recommended

certification TSS removal rate and the required maintenance plan. The NJCAT Verification Report with

the Verification Appendix (dated June 2017) for this device is published online at

http://www.njcat.org/verification-process/technology-verification-database.html.

The NJDEP certifies the use of the StormTrap SiteSaver® - 4 (STSS-4) Hydrodynamic Separator

by FreshCreek Technologies, Inc. at a TSS removal rate of 50% when designed, operated, and

maintained in accordance with the information provided in the Verification Appendix and the

following conditions:

1. The maximum treatment flow rate (MTFR) for the manufactured treatment device (MTD) is

calculated using the New Jersey Water Quality Design Storm (1.25 inches in 2 hrs) in N.J.A.C.

7:8-5.5.

2. The STSS-4 stormwater treatment device shall be installed using the same configuration

reviewed by NJCAT. Only model STSS-4 is certified under this letter, and the sizing information

is specified in item 6 below.

3. This STSS-4 stormwater treatment device cannot be used in series with another MTD or a media

filter (such as a sand filter) to achieve an enhanced removal rate for total suspended solids (TSS)

removal under N.J.A.C. 7:8-5.5.

4. Additional design criteria for MTDs can be found in Chapter 9.6 of the New Jersey Stormwater

Best Management Practices (NJ Stormwater BMP) Manual which can be found on-line at

www.njstormwater.org.

5. The maintenance plan for a site using this device shall incorporate, at a minimum, the

maintenance requirements for the STSS-4 stormwater treatment device. A copy of the

maintenance plan is attached to this certification. However, it is recommended to review the

maintenance website at http://stormtrap.com/wp-content/uploads/2016/05/SiteSaver-OM.pdf for any changes to the maintenance requirements.

6. Sizing Requirement:

The example below demonstrates the sizing procedure for the STSS-4 Stormwater Treatment

Device:

Example: A 0.25 acre impervious site is to be treated to 50% TSS removal using a

SiteSaver Stormwater Treatment Device. The impervious site runoff (Q) based

on the New Jersey Water Quality Design Storm was determined to be 0.79 cfs.

Maximum Treatment Flow Rate (MTFR) Evaluation:

The site runoff (Q) was based on the following:

time of concentration = 10 minutes

i = 3.2 in/hr (page 5-8, Fig. 5-3 of the NJ Stormwater BMP Manual)

c = 0.99 (curve number for impervious)

Q = ciA = 0.99 x 3.2 x 0.25 = 0.79 cfs

Given the site runoff is 0.79 cfs and based on Table 1 below, the STSS-4 with a MTFR of 4.32

cfs could be used for this site to remove 50% of the TSS from the impervious area without

exceeding the MTFR.

The sizing table corresponding to the STSS-4 model is noted below. This information can also be

found in the Verification Appendix of the NJCAT Verification Report. The sizing requirement

for the STSS-4 model hydrodynamic separator is as follows:

A detailed maintenance plan is mandatory for any project with a Stormwater BMP subject to the

Stormwater Management Rules, N.J.A.C. 7:8. The plan must include all of the items identified in the

Stormwater Management Rules, N.J.A.C. 7:8-5.8. Such items include, but are not limited to, the list of

inspection and maintenance equipment and tools, specific corrective and preventative maintenance tasks,

indication of problems in the system, and training of maintenance personnel. Additional information can

be found in Chapter 8: Maintenance and Retrofit of Stormwater Management Measures.

If you have any questions regarding the above information, please contact Mr. Shashi Nayak of my office

at (609) 633-7021.

SiteSaver® Manufacturer’s Instruction Manual

Regular inspections are recommended to ensure that the system is functioning as designed.

Please contact your Authorized SiteSaver Representative if you have questions regarding the

inspection and maintenance of the SiteSaver system. SiteSaver does not require entry into

the system for maintenance; however, it is prudent to note that prior to entry into any

underground storm sewer or underground structure, appropriate OSHA and local safety

regulations and guidelines should be followed.

Inspection Scheduling

The frequency of inspections and maintenance is site specific. Within the first year of

operation, it is recommended that the unit be inspected every six months to determine the

rate of pollutant accumulation. SiteSaver systems are recommended for inspection whenever

the upstream and downstream catch basins and stormwater pipes of the stormwater collection

system are inspected or maintained. This will minimize the cost of the inspection if it is done

at the same time. If checked on an annual basis, the inspection should be conducted before

the stormwater season begins to ensure that the system is functioning properly for the

upcoming storm season.

Inspection Process

Inspections should be done such that a sufficient time has lapsed since the most recent rain

event to allow for a static water condition. Visually inspect the system at all manhole

locations. For debris accumulation, visually inspect the netting component (if utilized) to

determine bag capacity. Nets containing only minor quantities of debris may be retained in

place. It is recommended to replace the nets when they appear 1/2 - 2/3 full. Failure to

replace nets and/or remove floatables from bypass screening (if applicable) will lead to

hydraulic relief, drain down deficiencies, and decrease the long-term functionality of the

system.

For sediment accumulation, utilize either a sludge sampler or a sediment pole to measure and

document the amount of sediment accumulation. To determine the amount of sediment in

the system with a sludge sampler follow the manufacturer’s instructions. If utilizing a

sediment pole, first insert the pole to the top of the sediment layer and record the depth.

Then, insert the pole to the bottom of the system and record the depth. The difference in the

two measurements corresponds to the amount of sediment in the system. Eight-inches of

sediment accumulation corresponds to the designed sediment storage capacity, four-inches

equates to 50% capacity, etc. Finally, inspect the inlet pipe opening to ensure that the silt

level or any foreign objects are not blocking the pipe.

Maintenance Process – Debris Removal

Maintenance should be done utilizing proper personal protective equipment such as: safety

glasses, hard-hat, gloves, first aid kit, etc. Maintenance should occur only when a sufficient

time has lapsed since the most recent rain event to allow for a static water condition for the

duration of the maintenance process.

For floatable debris removal, lift the netting bag by the frame, moving it upwards along the

netting support frame. To ease lifting the nets to the surface, gaff hooks or a service vehicle

(crane/hoist/boom truck) may be used. Slowly raise the netting frame allowing water in the

net to drain as it is raised to allow it to drip dry. Once the netting component is fully removed

from the system, it should be properly disposed of per local, state, and federal guidelines and

regulations. Typically, the netting component can be disposed of in a common dumpster

receptacle.

For sediment removal, the SiteSaver is designed with clear access at both the inlet and outlet.

A vacuum truck, or similar trailer mounted equipment, can be used to remove the sediment,

hydrocarbons, and water within the unit. For more effective removal, it is recommended to

use sewer jetting equipment or a spray lance to force the sediment to the vacuum hose.

When the floor is sufficiently cleaned, fill the system back to its normal water elevation (to

the pipe inverts).

Maintenance Process – Net Replacement

Install a new net assembly by sliding the netting frame down the support frame and ensure

the netting lays over the plate assembly. To order additional disposable nets, contact your

local SiteSaver representative. New nets come with tie wraps temporarily holding the net

material to the frame component for easy handling and storage. It is not recommended to

remove the tie wraps until the net is ready to be installed. The frame is tapered from top

(widest part) to bottom, and is also tapered from front (towards the sewer) to back. Cut the

tie wraps that secures the netting material to the frame for shipment and lower the net down

the guide rails. If debris has accumulated in the net support frame, remove the objects so

the new net seats fully in the channel when installed. If utilizing oil sorption socks, insert

them into the net cavity prior to lowering the net down the guide rails. The oil sorption socks

are designed to absorb approx. ¼ gallon of hydrocarbons; it is typically recommended to use

enough socks to absorb a gallon of hydrocarbons per treated cfs.

When lowering the net the following details should be exercised when placing the net:

• Watch the lowering to make sure that there are no unexpected entanglements.

• Be careful not to let the toe of the net get caught under the frame when it reaches the

bottom of the support frame. This is typically accomplished by holding the toe of the

net until after the net has started to prop into place.

• Finally, secure the access openings and properly dispose of the sediment per local,

state, and federal guidelines and regulations.

In the case of only floatables removal, a vacuum truck is not required. However, a vacuum

truck is required if the maintenance event is to include oil removal and/or sediment removal.

Proof of inspections and maintenance is the responsibility of the owner. All inspection reports

and data should be kept on site or at a location where they will be accessible for years in the

future. Some municipalities require these inspection and cleaning reports to be forwarded to

the proper governmental permitting agency on an annual basis. Refer to your local and

national regulations for any additional maintenance requirements and schedules not contained

herein. Inspections should be a part of the standard operating procedure. It is good practice

to keep records of rainfall events between maintenance events and the weight of material

removed, even if no report is required.

SiteSaver® Manufacturer’s Instruction Manual

Regular inspections are recommended to ensure that the system is functioning as designed.

Please contact your Authorized SiteSaver Representative if you have questions regarding the

inspection and maintenance of the SiteSaver system. SiteSaver does not require entry into

the system for maintenance; however, it is prudent to note that prior to entry into any

underground storm sewer or underground structure, appropriate OSHA and local safety

regulations and guidelines should be followed.

Inspection Scheduling

The frequency of inspections and maintenance is site specific. Within the first year of

operation, it is recommended that the unit be inspected every six months to determine the

rate of pollutant accumulation. SiteSaver systems are recommended for inspection whenever

the upstream and downstream catch basins and stormwater pipes of the stormwater collection

system are inspected or maintained. This will minimize the cost of the inspection if it is done

at the same time. If checked on an annual basis, the inspection should be conducted before

the stormwater season begins to ensure that the system is functioning properly for the

upcoming storm season.

Inspection Process

Inspections should be done such that a sufficient time has lapsed since the most recent rain

event to allow for a static water condition. Visually inspect the system at all manhole

locations. For debris accumulation, visually inspect the netting component (if utilized) to

determine bag capacity. Nets containing only minor quantities of debris may be retained in

place. It is recommended to replace the nets when they appear 1/2 - 2/3 full. Failure to

replace nets and/or remove floatables from bypass screening (if applicable) will lead to

hydraulic relief, drain down deficiencies, and decrease the long-term functionality of the

system.

For sediment accumulation, utilize either a sludge sampler or a sediment pole to measure and

document the amount of sediment accumulation. To determine the amount of sediment in

the system with a sludge sampler follow the manufacturer’s instructions. If utilizing a

sediment pole, first insert the pole to the top of the sediment layer and record the depth.

Then, insert the pole to the bottom of the system and record the depth. The difference in the

two measurements corresponds to the amount of sediment in the system. Eight-inches of

sediment accumulation corresponds to the designed sediment storage capacity, four-inches

equates to 50% capacity, etc. Finally, inspect the inlet pipe opening to ensure that the silt

level or any foreign objects are not blocking the pipe.

Maintenance Process – Debris Removal

Maintenance should be done utilizing proper personal protective equipment such as: safety

glasses, hard-hat, gloves, first aid kit, etc. Maintenance should occur only when a sufficient

time has lapsed since the most recent rain event to allow for a static water condition for the

duration of the maintenance process.

For floatable debris removal, lift the netting bag by the frame, moving it upwards along the

netting support frame. To ease lifting the nets to the surface, gaff hooks or a service vehicle

(crane/hoist/boom truck) may be used. Slowly raise the netting frame allowing water in the

net to drain as it is raised to allow it to drip dry. Once the netting component is fully removed

from the system, it should be properly disposed of per local, state, and federal guidelines and

regulations. Typically, the netting component can be disposed of in a common dumpster

receptacle.

For sediment removal, the SiteSaver is designed with clear access at both the inlet and outlet.

A vacuum truck, or similar trailer mounted equipment, can be used to remove the sediment,

hydrocarbons, and water within the unit. For more effective removal, it is recommended to

use sewer jetting equipment or a spray lance to force the sediment to the vacuum hose.

When the floor is sufficiently cleaned, fill the system back to its normal water elevation (to

the pipe inverts).

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
