Part II: Summary of Receiving Waters

Below is a list of waterbodies and segments that receive discharge from Milton's MS4. Additional water bodies located within the geographical boundaries of Milton will be included in the Town's Stormwater Management Program for completeness. These water bodies are within the Town of Milton's borders, but may receive discharge from other MS4s including those in other municipalities and Commonwealth of Massachusetts agencies.

For each waterbody segment, the number of outfalls discharging into it and any applicable impairments are listed. Only outfalls owned by the Town of Milton are counted in the summary below. Outfalls owned by the Commonwealth of Massachusetts and its agencies are not counted.

This information is based on information from the Town's data, the Neponset River Watershed Association, MassGIS OLIVER, and the Massachusetts 2014 Integrated List of Waters, found at this link: http://www.mass.gov/ eea/ docs/ dep/water/ reso u rces/ 07v5/16ilwplist. pdf .

As future MA Integrated Lists of Waters are published and approved, Milton will update its stormwater management plan and BMPs to reflect any changes.

Part Ill: Stormwater Management Program Summary

The tables below identify the Best Management Practices (BMPs) that the Town of Milton will employ to address each of the six Minimum Control Measures. For Minimum Control Measure 1, we identify a target audience for each BMP. We do not identify BMPs for an industrial audience because Milton does not have any industrial facilities or zoning for such.

The Town's MS4 discharges to receiving waters with a TMDL for fecal coliform, E.coli, and enterococcus. The Town's MS4 also discharges to receiving waters that have impairments for oil and grease, solids, and total phosphorus, but there are no approved TMDLs for these impairments. Due to these special characteristics, the Town will undertake additional BMPs to support the achievement of the waste load allocation for the TMDL and pollutant reduction for other impairments. These BMPs are identified later in Part Ill.

Part IV: Notes and additional information Certification information: The Town of Milton's Board of Selectmen voted to authorize Michael Dennehy, Town Administrator, to certify the Town's Notice of Intent for this permit on March 12, 2018.

ESA Eligibility Information: Enclosed please find a letter and list of species found in Milton issued by the US Fish and Wildlife Service. Also enclosed is a letter from Milton's Director of Public Works, Chase Berkeley, certifying that if the Town plans to install a structural BMP not identified in the NOi, the Town will conduct an endangered species screening for the proposed site.

Outfall Mapping information: To view the Town's outfall map, follow the link provided in Part I and select the "Drainage" layer of the GIS mapper. The Town's outfall map is represented in Part I as 97% complete to account for recent changes to the town drainage that have not yet been updated.

The Town has determined that the following parts of permit sections 2.2.1 and 2.2.2 do not apply to the Town because Milton is not located in the watersheds to which they apply, and therefore is not listed under these sections:

• 2.2.l(b).i - Charles River Watershed, phosphorus TMDL • 2.2.l(b).ii - Northern Blackstone Basin - phosphorus TMDL • 2.2.l(b).iv- Cape Cod municipalities - nitrogen TMDL • 2.2.l(b).v-Assabet River Watershed - phosphorus TMDL • 2.2.l(c).i - Long Island Sound municipalities- nitrogen TMDL • 2.2.l(c).ii - out of state phosphorus TMDL • 2.2.l(c).iii - out of state bacteria/pathogens TMDL • 2.2.l(c).iv - out of state metals TMDL • 2.2.2(a) - discharges to water quality limited bodies where nitrogen is the cause of the impairment • 2.2.2(d) - discharges to water quality limited bodies where chloride is the cause of the impairment

Additional information about our MS4 program:

• As the 2016 permit requires, the Town will continue to implement our existing SWMP and control measures from the MS4-2003 permit. However, some of those minimum control measures will be reincorporated into new or renumbered BMPs in order to simplify the stormwater management plan where possible.

• Under the 2003 General Permit, some of the area of the Town of Milton was not part of the regulated area. Under the 2016 permit, the entire Town is within the regulated area.

• Within the Town of Milton there are a significant number of properties, catch basins, and outfalls that belong to the Commonwealth of Massachusetts and its agencies. While these items may appear in the Town's stormwater management maps, the Town of Milton is not responsible for maintenance and screening of infrastructure that belongs to the Commonwealth. The Town's outfall map should not be used as an official map of infrastructure belonging to the Commonwealth.

In Reply Refer To: May 31, 2018 Consultation Code: 05E1NE00-2017-SLI-2763 Event Code: 05E1NE00-2018-E-04624 Project Name: NPDES Small MS4 permit

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

To \Vhom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered 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 of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us ifyou need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through 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 the ecosystems upon which they depend may be conserved. Under sections 7(a)(l) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.

http://www.fws.gov/newen2Jand

05/31/2018 Event Code: 05E1 NE00-2018-E-04624 2

A Biological Assessment is required for construction projects ( or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the 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 biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species 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 Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats.

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

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

From: Hillary Waite To: Kozminski, Michelle Cc: Reports Stormwater Subject: RE: Small MS4 NOI submission - additional or corrected information required Date: Tuesday, September 25, 2018 1:51:22 PM Attachments: NOI_Corrections.pdf

Hi Michelle,

Thanks for reaching out.

- BMP 5-7 has been revised so that the list of properties will be completed by 2022. - A BMP has been added to inventory permittee-owned parks and open spaces, buildings and facilities, and vehicles and equipment. I added it as BMP 6-1 since it is foundational to 6-2, so other BMPs in section 6 have been renumbered. - BMP 6-2 (now BMP 6-3) has been revised to indicate that infrastructure O&M procedures will be implemented following permit requirements. - BMP 6-10 (now 6-11) has an expected implementation date of 2023.

I am attaching a revised NOI pages 1-12 to reflect these changes. Please let me know if these are acceptable or if I can provide any additional information.

Best,

Hillary Waite Environmental Coordinator Milton Department of Public Works 525 Canton Avenue Milton, MA 02186 617-898-4968

Part II: Summary of Receiving Waters Below is a list of waterbodies and segments that receive discharge from Milton’s MS4. Additional water bodies located within the geographical boundaries of Milton will be included in the Town’s Stormwater Management Program for completeness. These water bodies are within the Town of Milton’s borders, but may receive discharge from other MS4s including those in other municipalities and Commonwealth of Massachusetts agencies. For each waterbody segment, the number of outfalls discharging into it and any applicable impairments are listed. Only outfalls owned by the Town of Milton are counted in the summary below. Outfalls owned by the Commonwealth of Massachusetts and its agencies are not counted. This information is based on information from the Town’s data, the Neponset River Watershed Association, MassGIS OLIVER, and the Massachusetts 2014 Integrated List of Waters, found at this link: http://www.mass.gov/eea/docs/dep/water/resources/07v5/16ilwplist.pdf . As future MA Integrated Lists of Waters are published and approved, Milton will update its stormwater management plan and BMPs to reflect any changes. Waterbody segment

Part III: Stormwater Management Program Summary

Part III: Stormwater Management Program Summary The tables below identify the Best Management Practices (BMPs) that the Town of Milton will employ to address each of the six Minimum Control Measures. For Minimum Control Measure 1, we identify a target audience for each BMP. We do not identify BMPs for an industrial audience because Milton does not have any industrial facilities or zoning for such. The Town’s MS4 discharges to receiving waters with a TMDL for fecal coliform, E. coli, and enterococcus. The Town’s MS4 also discharges to receiving waters that have impairments for oil and grease, solids, and total phosphorus, but there are no approved TMDLs for these impairments. Due to these special characteristics, the Town will undertake additional BMPs to support the achievement of the waste load allocation for the TMDL and pollutant reduction for other impairments. These BMPs are identified later in Part III. Minimum Control Measure 1: Public Education and Outreach BMP Number

Part IV: Notes and additional information

Part IV: Notes and additional information Certification information: The Town of Milton’s Board of Selectmen voted to authorize Michael Dennehy, Town Administrator, to certify the Town’s Notice of Intent for this permit on March 12, 2018.

ESA Eligibility Information: Enclosed please find a letter and list of species found in Milton issued by the US Fish and Wildlife Service. Also enclosed is a letter from Milton’s Director of Public Works, Chase Berkeley, certifying that if the Town plans to install a structural BMP not identified in the NOI, the Town will conduct an endangered species screening for the proposed site.

Outfall Mapping information: To view the Town’s outfall map, follow the link provided in Part I and select the “Drainage” layer of the GIS mapper. The Town’s outfall map is represented in Part I as 97% complete to account for recent changes to the town drainage that have not yet been updated.

The Town has determined that the following parts of permit sections 2.2.1 and 2.2.2 do not apply to the Town because Milton is not located in the watersheds to which they apply, and therefore is not listed under these sections:

2.2.1(b).i – Charles River Watershed, phosphorus TMDL 2.2.1(b).ii – Northern Blackstone Basin – phosphorus TMDL 2.2.1(b).iv – Cape Cod municipalities – nitrogen TMDL 2.2.1(b).v – Assabet River Watershed – phosphorus TMDL 2.2.1(c).i – Long Island Sound municipalities – nitrogen TMDL 2.2.1(c).ii – out of state phosphorus TMDL 2.2.1(c).iii – out of state bacteria/pathogens TMDL 2.2.1(c).iv – out of state metals TMDL 2.2.2(a) – discharges to water quality limited bodies where nitrogen is the cause of the impairment 2.2.2(d) – discharges to water quality limited bodies where chloride is the cause of the impairment

Additional information about our MS4 program:

As the 2016 permit requires, the Town will continue to implement our existing SWMP and control measures from the MS4‐2003 permit. However, some of those minimum control measures will be reincorporated into new or renumbered BMPs in order to simplify the stormwater management plan where possible.

Under the 2003 General Permit, some of the area of the Town of Milton was not part of the regulated area. Under the 2016 permit, the entire Town is within the regulated area.

Within the Town of Milton there are a significant number of properties, catch basins, and outfalls that belong to the Commonwealth of Massachusetts and its agencies. While these items may appear in the Town’s stormwater management maps, the Town of Milton is not responsible for maintenance and screening of infrastructure that belongs to the Commonwealth. The Town’s outfall map should not be used as an official map of infrastructure belonging to the Commonwealth.

Town of Milton, MA Page 2 of 13


Below is a list of waterbodies and segments that receive discharge from Milton’s MS4. Additional water bodies located within the geographical boundaries of Milton will be included in the Town’s Stormwater Management Program for completeness. These water bodies are within the Town of Milton’s borders, but may receive discharge from other MS4s including those in other municipalities and Commonwealth of Massachusetts agencies.

For each waterbody segment, the number of outfalls discharging into it and any applicable impairments are listed. Only outfalls owned by the Town of Milton are counted in the summary below. Outfalls owned by the Commonwealth of Massachusetts and its agencies are not counted.

This information is based on information from the Town’s data, the Neponset River Watershed Association, MassGIS OLIVER, and the Massachusetts 2014 Integrated List of Waters, found at this link: http://www.mass.gov/eea/docs/dep/water/resources/07v5/16ilwplist.pdf .

As future MA Integrated Lists of Waters are published and approved, Milton will update its stormwater management plan and BMPs to reflect any changes.

For Minimum Control Measure 1, we identify a target audience for each BMP. We do not identify BMPs for an industrial audience because Milton does not have any industrial facilities or zoning for such.

The Town’s MS4 discharges to receiving waters with a TMDL for fecal coliform, E. coli, and enterococcus. The Town’s MS4 also discharges to receiving waters that have impairments for oil and grease, solids, and total phosphorus, but there are no approved TMDLs for these impairments. Due to these special characteristics, the Town will undertake additional BMPs to support the achievement of the waste load allocation for the TMDL and pollutant reduction for other impairments. These BMPs are identified later in Part III.
