1.0 INTRODUCTION Sovereign Consulting Inc. (Sovereign) prepared this National Pollutant Discharge Elimination System (NPDES) Remediation General Permit (RGP) application on behalf of Shell Oil Products US (SOPUS) to manage treated groundwater which will be discharged into the municipal storm catch basin located on Sharon Street in Stoughton, Massachusetts. The residually impacted groundwater will be generated from dewatering during underground storage tank (UST) system installation. This site is identified by the Massachusetts Department of Environmental Protection (MassDEP) as Release Tracking Number (RTN) 4-15064 and is regulated in accordance with the Massachusetts Contingency Plan (MCP) 310 CMR 40.0000. Accordingly, discharges subject to the MCP do not require the completion of a state application form BRPWM 12 or state fee payment. A Site Location Map and discharge location is provided as Figure 1 and a Site Plan, depicting relevant site features including the municipal storm system location, is attached as Figure 2. Figure 3 presents a Typical Groundwater Dewatering Installation Diagram. A Waterbody Assessment and TMDL Status for Canton, Massachusetts (the discharge location for the storm drain outfall) is provided as Figure 4. The MassDEP Bureau of Waste Site Cleanup Phase I Site Assessment Map, dated July 5, 2017, is provided as Figure 5. For the purpose of this investigation, the “facility” is defined as the area located within the property boundaries of 140 Sharon Street, Stoughton, Massachusetts. The “disposal site” is defined as the property and other properties where oil and/or hazardous material (OHM) has come to be located as a result of the release from the property. Relevant Contacts: Facility/Facility Owner: Colbea Enterprises LLC 2050 Plainfield Pike Cranston, Rhode Island 02921 Contact: Thomas Breckel Tel: (401) 943-0005 Facility Operator: Colbea Enterprises LLC 2050 Plainfield Pike Cranston, Rhode Island 02921 Contact: Thomas Breckel Tel: (401) 943-0005 2.0 PROJECT SUMMARY 2.1 Site Description The facility is located in a mixed commercial/residential area of Stoughton, Massachusetts and has operated as a gasoline station since at least the 1960s. This Shell-branded station is currently owned by Colbea Enterprises LLC (Colbea). A one-story building with a convenience store and a car wash are located on the southern portion of the property. Two 10,000-gallon gasoline and


2

one 8,000-gallon gasoline underground storage tanks (USTs) are located on the northwest portion of the facility. The existing USTs are constructed of single-walled, fiberglass-reinforced plastic with product line leak detection and an in-tank monitor. The station and carwash buildings are heated via electric, forced hot-air systems. Electricity and telephone services enter the property via overhead lines from a utility pole at the eastern property corner. Electric and telephone service lines continue underground to the facility building. Natural gas, water, and sewer are supplied to the facility via underground utility lines entering the property from the east. The areas surrounding the structures are paved with asphalt. Entrances to the property are located on Sharon Street and Bay Road. Colbea anticipates removing the entire UST system, demolishing the site building, installing a new UST system, and constructing a new site building in the near future. The disposal site is a commercial property and does not have a NPDES permit or prior application. Dewatering activities associated with this RGP application are associated with excavation for the installation of replacement USTs. 2.2 Sensitive Receptors According to data obtained from the MassDEP Bureau of Waste Site Cleanup (BWSC) Phase 1 Site Assessment Map, dated July 5, 2017, Figure 5, the disposal site is not located within a Current or Potential Drinking Water Source Area, Zone II or Interim Wellhead Protection Area (IWPAs). No other potentially sensitive environmental receptors have been identified within a 500-foot radius of the disposal site. A residential property, identified as 2351 Central Street in Stoughton, is located adjacent to the southeastern corner of the subject property and utilizes a private water supply well for drinking water purposes. The private drinking water supply well on that property is located approximately 300 feet southeast of the disposal site in the inferred upgradient direction. No schools, hospitals, daycare centers, or long-term health care facilities were identified within 500 feet of the disposal site. There are no IWPAs, surface water supply Zone A areas, Potentially Productive Aquifers, Non-Potentially Productive Aquifers, wetlands, Protected Open Spaces, Priority Habitats of Rare Species, vernal pools, or Areas of Critical Environmental Concern (ACEC) identified within 500 feet of the disposal site. The nearest surface water bodies are Shephard Pond and Massapoag Brook, approximately 1,600 feet northwest of the disposal site boundary. Wetlands are located within ½ mile of the disposal site in the southwest, east and northeast directions. The nearest wetlands are located approximately 625 feet downgradient, in the northwest direction of the facility. A potential vernal pool is located approximately ½ mile from the disposal site boundary. A FEMA 100-year floodplain and protected open space are located within ½ mile radius of the disposal site. A non-potential drinking water source area of medium yield and a medium yield aquifer are located approximately 1,125 feet southeast of the disposal site. 3.0 DISCHARGE INFORMATION 3.1 Influent and Receiving Water Sampling An influent sample was collected from groundwater at monitoring well MW-1, which is located within the area where construction dewatering will be required. A receiving water sample was


3

collected from the nearest accessible surface water location in Massapoag Brook. Both groundwater samples were collected on June 1, 2017 and analyzed by a State of Massachusetts certified laboratory for the parameters required by the RGP Permit. The sample results, laboratory methods, laboratory method detection limits, and the total maximum daily mass of contaminants of concert (COCs) anticipated to be discharged have been summarized in the Notice of Intent form provided as Attachment A, and the laboratory analytical report included as Attachment B.

3.1.1 Influent Sample Results The influent sample results from groundwater collected at monitoring well MW-1 chloride and hardness parameters, below the effluent limit listed in Section D of the NOI form. Effluent samples were not collected at the time of sampling because the dewatering treatment system is not installed. On the NOI form, all analytes detected above the laboratory detections limits from the June 1, 2017 sampling event were recorded as “Known or Believed Present” and all analytes detected below the laboratory detections limits were recorded as “Known or Believed Absent”. The two exceptions were tert-butyl alcohol (TBA) and tertiary-amyl methyl ether (TAME), which have historically been detected at this location, but have not been detected in recent years. These two analytes have been conservatively categorized as “Known or Believed Present.”

3.1. Dilution Factor SOPUS evaluated the potential concentration considering a dilution factor (DF) using the formula below: Dilution Factor (DF) Calculation: DF = (Qs + Qd) / Qd

Where:

DF = Dilution Factor Qd = Maximum flow rate of the discharge in cubic feet per second (cfs) (1.0

gpm =0.002676 cfs) Qs = Receiving water 7Q10 flow (cfs) where 7Q10 is the minimum flow (cfs) for 7

consecutive days with a recurrence interval of 10 years Estimated flow rates are based on the maximum flow rate of 50 gpm and the United States Geological Society 7Q10 flow data for Massapoag Brook, the dilution factor is as follows:

DF = (Qs + Qd) / Qd Qd = .0.072 MGD Qs = 0.275 DF = (0.275 +0.072)/ 0.072 DF= 4.82

SOPUS anticipates that the treatment system will remove the majority of dissolved iron from the effluent water stream prior to discharge to the storm water drain which discharges to Dam Lot Brook. If needed, a modification to the system may be required which will include the incorporation of a sequestering agent to keep iron in solution. Any modifications to the system will be submitted for approval by a Notice of Change (NOC). The calculated dilution factor and effluent limitation calculations are included as Attachment C. 4.0 TREATMENT SYSTEM INFORMATION 4.1 System Design The sump water treatment system will be located in on the disposal site, located at 140 Sharon Street in Stoughton, Massachusetts. The system will be composed of the following: one submersible sump pump locate within each sub-grade sump, a pre-treatment holding tank, two bag filters piped in parallel to filter out particulates, two influent 200-pound or greater liquid phase granular activated carbon (LGAC) units piped in parallel and two effluent 200-pound or greater LGAC units piped in parallel, and a post-treatment holding tank. The flow rate of the system is designed to pump, treat, and discharge up to 50 gpm, but is expected to range from 1 to 20 gpm. The component of the system with the most limited flow will be the LGACs. The proposed discharge location for treated groundwater is a municipal storm drain catch basin located adjacent to the property line, on Sharon Street adjacent to the disposal site as depicted on Figure 2. This storm drain discharges to a wetland that feeds Massapoag Brook. Refer to Figure 4 for a typical Groundwater Dewatering Installation Diagram. 5.0 RECEIVING SURFACE WATER The proposed discharge location for treated groundwater is a municipal storm drain catch basin located adjacent to the property line, on Sharon Street as depicted on Figure 2. This storm drain discharges to a wetland that feeds Massapoag Brook. The discharge point to the wetland is located 350 feet to the northwest of the disposal site. The Town of Canton Town Engineer and Conservation Commission were both notified in writing of the planned discharge of treated groundwater to the wetland feeding Massapoag Brook. Both departments will be contacted again following submittal of the RGP application. Copies of the notification letters are included as Attachment D. 5.1 Receiving Water Information The receiving water for the indirect discharge of the treated groundwater discharge is Massapoag Brook. On June 19, 2017, Sovereign consulted the online United States Geological Survey (USGS) Streamstats program to determine the 7Q10 flow rate at the discharge location. Data obtained from the online resource indicated that the 7Q10 flow rate for Massapoag Brook at USGS station #01105270 is 0.426 cubic feet per second (cfs). Based on data available, Sovereign calculated a 7Q10 flow rate for this area to be approximately 0.275 million gallons per day (mgd).

Per the Waterbody Assessment and TMDL Status Map for Canton, Massachusetts, Massapoag Brook is listed as a Category 5 impaired or threatened water body. Category 5 is water that is impaired or threatened for one of more uses and required a TMDL. A copy of the Waterbody Assessment and TMDL Status Map for Canton, Massachusetts is included as Figure 4. 5.2 Receiving Water Classification Sovereign consulted the MassDEP Division of Water Pollution Control to determine the classification for the receiving waters. Massapoag Brook, segment MA73-21, is listed as Class B. 6.0 ESA AND NHPA ELIGIBILITY 6.1 Endangered Species Act Guidance In accordance with Appendix I and II of the RGP regulations, Sovereign personnel reviewed the regulations to determine if the proposed discharge to the storm drain on Sharon Street, which discharges to a wetland that feeds Massapoag Brook, is in compliance with the Endangered Species Act (ESA) eligibility criteria. Based on the ESA Eligibility Criteria, the applicable criterion is “Criterion B”. Criterion B states that a formal or informal consultation with the Fish and Wildlife Service (FWS) under section 7 of the ESA resulted in either a no jeopardy opinion (formal consultation) or a written concurrence by FWS on a finding that the discharges and related activities are “not likely to adversely affect” listed species or critical habitat (informal consultation). While one threatened species (the northern long eared bat) exists within this portion of the Massapoag Brook and wetland area, the planned discharge of treated groundwater is considered not likely to adversely affect this species. In addition, there are no critical habitats located in the vicinity of the project area. Correspondence with the FWS is included as Attachment E. 6.2 National Historic Preservation Act In accordance with Appendix III of the RGP regulations, Sovereign personal reviewed electronic listings to determine if any historic properties, or properties eligible for listing on the National Register of Historic Places, are within the path of the discharge or discharge related activities. Listings of Historic Places within the Town of Canton, in the vicinity of the proposed discharge area of Massapoag Brook and associated wetland were obtained from the Massachusetts Cultural Resources Information System (MACRIS) online database, accessed July 6, 2017). A copy of the MACRIS report is provided as Attachment F. The database indicated that Massapoag Brook and its associated wetland are not registered as historic properties. There are several historic places located in proximity to the proposed discharge area. Upon review of the listed locations, It has been determined that the listed properties are located upgradient from Massapoag Brook and its associated wetland area, and are unlikely to be impacted from the planned discharge of treated groundwater to the wetland area. In accordance with Part IIC of Appendix III of the RGP regulations, Permit Eligibility Criterion B is applicable. Criterion B states that “Historic properties are present. Discharges and discharge related activities do not have the potential to cause effects on historic properties.” This project does not involve the demolition or rehabilitation of existing buildings or other


6

structures or facilities and historic properties are not affected by the discharge or identified in the path of the discharges regulated by this permit.

Hi Jim, Thank you so much for working with us together to make sure you have the right numbers for the 7Q10 and the dilution factor. Please see the attached SteamStats report. I am not sure why our reports are in different formats and give us different values, maybe they were run by different versions? BTW, I used StreamStats 4.0. The 7Q10 in the attached report is 0.426 cfs. Could you please take a look at it and let me know if you have any questions? Thanks.

The coordinates you listed below are indeed what the Streamstats 7Q10 was based on – unless I misinterpreted it. See attached. When I sent this to you last week, it seems I forgot to double‐side the scanner, so you didn’t get all of our calculations. With this attachment you’ll see the page where we captured the 7Q10 flow and converted it from cfs to mgd. Sorry about that. Jim James M.

Could you please send me your StreamStats report? Cause I got a different 7Q10 by using the coordinates you provided in the earlier email, Lat – 42.1495436, Long ‐ ‐71.14949528. It will be very helpful if I can see in the report where you clicked exactly. Thank you. Xiaodan From: Smith, James [mailto:[email protected]] Sent: Monday, July 10, 2017 11:39 AM To: Ruan, Xiaodan (DEP) Subject: RE: Receiving Water Lookup Hi Xiaodan, thanks for your attention to working through this with me. For the GPs coordinates we used, Streatstats provided a 7Q10 of 0.7 cfs, which we converted to 0.452 MGD. So using 0.452, and using a design flow of 50 gpm (converted to 0.072 MGD) is how we came up with a dilution factor of 7.278. I don’t want to dispute the result, I just want to make sure I am calculating correctly. Can you please confirm that we did the cfs‐MGD conversion correctly or incorrectly? Thanks so much for your patience.

From: Ruan, Xiaodan (DEP) [mailto:[email protected]] Sent: Friday, July 07, 2017 3:01 PM To: Vakalopoulos, Catherine (DEP) <[email protected]>; Smith, James <[email protected]> Subject: RE: Receiving Water Lookup Hi Jim, I clicked on the stream cell that is very close to the coordinates that you gave and received a slightly different 7Q10 (see attached report). The 7Q10 in the report is 0.426 cfs, that equals to 0.229 MGD. So the dilution factor is: (0.229 MGD +0.072 MGD) / 0.072 MGD = 4.18. This value does not match what you had. Could you please send us your calculation? Thank you!

You will have to contact EPA. Shauna Little is on vacation but she said to have people contact George Papadopoulos 617‐918‐1579 or Newton Tedder 617‐918‐1038. I know George is in today so start with him.

The system will likely be running more like 20‐30 gpm when it is running. I also have another question – in Sections G and H – am I required to contact someone at FWS, NMFS, or NHPA as applicable, and get a written document from those parties in order to consider the determinations in these sections valid for the RGP application? Or can my review of available data (mainly online resources) suffice as a valid determination, to support this application? Jim James M. Smith Senior Project Manager | email:

Please check the attached StreamStats report because I came up with a different 7Q10 than you (I made sure to convert cfs to MGD and it was still different). It’s probably because I guessed at the exact discharge location and so please send me the lat/long of the discharge location on Massapoag Brook. If you didn’t save the StreamStats report, please run it again and you will see a lat/long of the location you clicked on to delineate. Also, please confirm that the 0.072 MGD (50 gpm) is indeed the design flow and not an average flow. Thanks!

Here is where you can find the classification (A, B, SA, or SB): http://www.mass.gov/eea/docs/dep/water/laws/i‐thru‐z/tblfig.pdf. Waterbody IDs can be found in water quality assessment reports here: http://www.mass.gov/eea/agencies/massdep/water/watersheds/water‐quality‐assessments.html. Open the latest report for the watershed you are working in and do a search for the waterbody ID (also known as the segment, it looks like “MA##‐##). Larger rivers are split up into several segments and smaller stream may not have an ID so just list the name in the NOI. Let me know if you have any trouble and I can look for you.

Dewatering of petroleum-impacted groundwater will be conducted during gasoline station redevelopment construction activities beginning in later July 2017, and continuing through August 2017. During the construction, existing gasoline underground storage tanks (USTs), pump islands, and associated piping will be removed and replaced with a new UST system. Dewatering of groundwater will be performed during the installation of the replacement USTs, as the excavation depth for the replacement USTs will extend into the groundwater table. Groundwater dewatered during the construction activities will be treated through a series of bag filters and carbon filter units, under the NPDES RGP permit referenced above, prior to being discharged to the storm drain system, which discharges to a wetland area that feeds Massapoag Brook. A copy of the NDPES RGP application will be available upon request, once complete. Please feel free to contact me with any questions at the office number below, or by my mobile phone at 781-588-7370.

In Reply Refer To:Consultation Code: 05E1NE00-2017-SLI-2037Event Code: 05E1NE00-2017-E-04460 Project Name: Massapoag Brook Wetland - Canton, MA

Subject: List of threatened and endangered species that may occur in your proposed projectlocation, and/or may be affected by your proposed project

To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, aswell as proposed and final designated critical habitat, that may occur within the boundary of yourproposed project and/or may be affected by your proposed project. The species list fulfills therequirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of theEndangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 ).et seq.

New information based on updated surveys, changes in the abundance and distribution ofspecies, changed habitat conditions, or other factors could change this list. Please feel free tocontact us if you need more current information or assistance regarding the potential impacts tofederally proposed, listed, and candidate species and federally designated and proposed criticalhabitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of theAct, the accuracy of this species list should be verified after 90 days. This verification can becompleted formally or informally as desired. The Service recommends that verification becompleted by visiting the ECOS-IPaC website at regular intervals during project planning andimplementation for updates to species lists and information. An updated list may be requestedthrough the ECOS-IPaC system by completing the same process used to receive the enclosed list.

The purpose of the Act is to provide a means whereby threatened and endangered species and theecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of theAct and its implementing regulations (50 CFR 402 ), Federal agencies are required toet seq.utilize their authorities to carry out programs for the conservation of threatened and endangeredspecies and to determine whether projects may affect threatened and endangered species and/ordesignated critical habitat.

A Biological Assessment is required for construction projects (or other undertakings havingsimilar physical impacts) that are major Federal actions significantly affecting the quality of the

http://www.fws.gov/newengland

07/10/2017 Event Code: 05E1NE00-2017-E-04460 2

human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)(c)). For projects other than major construction activities, the Service suggests that a biologicalevaluation similar to a Biological Assessment be prepared to determine whether the project mayaffect listed or proposed species and/or designated or proposed critical habitat. Recommendedcontents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, thatlisted species and/or designated critical habitat may be affected by the proposed project, theagency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Servicerecommends that candidate species, proposed species and proposed critical habitat be addressedwithin the consultation. More information on the regulations and procedures for section 7consultation, including the role of permit or license applicants, can be found in the "EndangeredSpecies Consultation Handbook" at:

http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF

Please be aware that bald and golden eagles are protected under the Bald and Golden EagleProtection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq.development of an eagle conservation plan(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projectsshould follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizingimpacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communicationstowers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;http://www.towerkill.com; andhttp://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.

We appreciate your concern for threatened and endangered species. The Service encouragesFederal agencies to include conservation of threatened and endangered species into their projectplanning to further the purposes of the Act. Please include the Consultation Tracking Number inthe header of this letter with any request for consultation or correspondence about your projectthat you submit to our office.
