INTRODUCTION

Executive Summary

Each community with a municipal separate storm sewer system (MS4) in designated urbanized areas must develop a Stormwater Management Program (SWMP) that will guide its activities under the 2016 MS4 general permit. This SWMP was developed by the City of Taunton to protect water quality and reduce the discharge of pollutants from the municipality’s storm sewer system to the maximum extent practicable (MEP) as described herein.

The SWMP is comprised of four documents.

· SWMP – Stormwater Management Plan · SWMP – Illicit Discharge Detection and Elimination (IDDE) Plan · SWMP – Operations and Maintenance (O&M) Plan · SWMP – Annual Reporting

Written plans for Stormwater Management Plan and the IDDE Plan are required to be completed by the end of year 1 of the permit term (June 30, 2019). The Operations and Maintenance (O&M) Plan is required to be completed by the end of year 2 of the permit term (June 30, 2020). The Annual Reporting manuscript compiles the documentation required over each reporting period (July 1 to June 30) for assembly of annual reports due September 30th each year.

Stormwater Regulation

The Stormwater Phase II Final Rule was promulgated in 1999 and was the next step after the 1987 Phase I Rule in EPA's effort to preserve, protect, and improve the Nation's water resources from polluted stormwater runoff. The Phase II program expands the Phase I program by requiring additional operators of MS4s in urbanized areas and operators of small construction sites, through the use of NPDES permits, to implement programs and practices to control polluted stormwater runoff. Phase II is intended to further reduce adverse impacts to water quality and aquatic habitat by instituting the use of controls on the unregulated sources of stormwater discharges that have the greatest likelihood of causing continued environmental degradation. Under the Phase II rule all MS4s with stormwater discharges from Census designated Urbanized Areas are required to seek NPDES permit coverage for those stormwater discharges.

Permit Program Background

On May 1, 2003, EPA Region I issued its Final General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems (MS4-2003 permit) consistent with the Phase II rule. The MS4- 2003 permit covered "traditional" (i.e., cities and towns) and "non-traditional" (i.e., Federal and state agencies) MS4 Operators located in the states of Massachusetts and New Hampshire. This permit expired on May 1, 2008 but remained in effect until operators were authorized under the 2016 MS4 general permit, hereinafter referred to as the Permit, which became effective on July 1, 2018.

City Specific MS4 Background

Taunton has 17 water body segments designated as “impaired waters” within the boundaries of the city with five designated as Category 5 Waters, two designated as Category 4A, and four designated as Category 4C. Two of these waterbodies, Big Bearhole Pond and Cain Pond, do not receive direct

1 Stormwater Management Program June 2019 Taunton, Massachusetts discharges from municipal storm drains. A breakdown of the impairments related to each waterbody is provided in the Resource Protection section of this report. Several waterbodies have bacteria, phosphorus, and nitrogen impairments which require specific actions under the Permit. Additional impairments and required actions are described in detail in the Resource Protection section of this report.

The City of Taunton’s MS4 is composed of pipes, catch basins, manholes, culverts, swales and outfalls discharging to wetland areas, streams, lakes, ponds and rivers. A GIS database has been established which contains City-wide information for all of the drainage structures including:

· 5,861 catch basins from the City database o 4,357 designated City-owned o 375 designated State-owned o 1,129 designated privately owned · 78 curb inlets from the City database o Data layer does not include a field for ownership designation · 658 outfalls from the City database that were during inspection from 2016 to 2018. o Only includes outfalls designated as City-owned · 3,316 storm drain manholes from the City database o 3,078 designated City-owned o 88 designated State-owned o 150 designated privately owned

A storm sewer system map is included as part of the Illicit Discharge Detection and Elimination (IDDE) report, and is also located in Appendix D. The map includes stormwater system structures and identifies the impaired water bodies and the MS4 areas tributary to each.

Massachusetts Department of Transportation (MassDOT) has several roads within Taunton including Route 24, Route 44, and I-495. MassDOT is required to have their own NPDES MS4 Permit for their properties, which are therefore not the responsibility of the City.

Stormwater Management Program

The City was previously authorized by the MS4-2003 permit which had established six minimum control measures, Best Management Practice (BMPs) and measurable goals to meet the terms and conditions of that permit. This SWMP is a modification and update to the previous plan and efforts.

The SWMP describes and details the activities and measures that will be implemented to meet the terms and conditions of the Permit. The SWMP accurately describes the City’s plans and activities. The document will be updated and/or modified during the Permit term as the permittee's activities are modified, changed or updated to meet Permit conditions during the Permit term. The main elements of the stormwater management program are (1) a public education program in order to change public behavior causing stormwater pollution, (2) an opportunity for the public to participate in and provide comments on the stormwater program, (3) a program to effectively find and eliminate illicit discharges within the MS4, (4) a program to effectively control construction site stormwater discharges to the MS4, (5) a program to ensure that stormwater from development projects entering the MS4 is adequately controlled by the construction of stormwater controls, and (6) a good housekeeping program to ensure that stormwater pollution sources on municipal properties and from municipal operations are minimized.

This document will be made available at the office of the Taunton Department of Public Works and on the City website. The Permit covers the following which are included in this SWMP Plan:

RESOURCE PROTECTION

Endangered and Threatened Species

The Permit requires applicants to assess the impacts of their stormwater discharges and discharge related activities on federally listed endangered and threatened species and designated critical habitat.

The NOI submitted in September of 2018 for coverage under the Permit identified two federally listed endangered species of concern, the Northern Long-eared Bat and the Plymouth Redbelly Turtle, and determined eligibility for Endangered Species Act (ESA) under Criteria C. An ESA section 7 consultation was provided for the NOI certifying the activities under the Permit, and as described in this SWMP, will not adversely affect the Northern Long-eared Bat or the Plymouth Redbelly Turtle. There is no reason to believe that the stormwater discharges, allowable non-stormwater discharges and discharge related activities will have any effect on this or any other listed species or critical habitat. This is based on the following:

1. All stormwater discharges are pre-existing or previously permitted by EPA; 2. Any planned operations and maintenance work covered by this permit will only affect previously disturbed areas where stormwater controls are already installed. In these situations the chance of encountering and of the subject species is discountable; 3. The project implements EPA MS4 Best Management Practices (BMPs) and meets Clean Water Act and Massachusetts Water Quality Standards. Although permitted discharges may reach the environment used by these species, BMPs reduce pollutants to the extent that discharges are not known to have measurable impacts on these species or their habitat; 4. No new construction or structural BMPs are proposed under this permit at this time; and 5. It is agreed that if, during the course of the permit term, it is planned to install a structural BMP not identified in the Notice of Intent (NOI), the City will re-initiate with the U.S. Fish and Wildlife Services as necessary. 6. A determination by the U.S. Fish and Wildlife Service confirming these assumptions is attached in Appendix B, along with other supporting documentation obtained to reach this determination.

The aforementioned requirements are all met under this Permit and as such there is no reason to believe that the stormwater discharges, allowable non-stormwater discharges and discharge related activities will have any adverse effect on the aforementioned species or any other listed species or critical habitat. If any future stormwater projects or activities are proposed the City acknowledges that they will have to re- initiate either informal or formal consultation with USFWS as required under the MA MS4 General Permit Appendix C: Step 2(5).

The Environmental Overview Map in Appendix C includes Natural Heritage and Endangered Species Program (NHESP) estimated habitats of rare wildlife, priority habitats of rare species, certified vernal pools and wetlands. Future stormwater projects and activities proposed within these areas will require review for compliance with the Massachusetts ESA and the Wetlands Protection Act.

Historic Properties

The MS4 Permit requires applicants to take into account the effects of Federal undertakings on historical properties that are either listed on or eligible for listing on the National Register of Historic Places. The NOI identified eligibility for National Historic Preservation Act under Criteria A. The proposed BMPs outlined in this program have no potential to affect any historic properties because no changes are proposed to the existing MS4 infrastructure.

5 Stormwater Management Program June 2019 Taunton, Massachusetts

The Environmental Overview Map in Appendix C includes the Massachusetts Historical Commission’s (MHC) inventory of historic points and areas. Future stormwater projects and activities proposed in and around these properties should be referenced against this map as well as the state register. The state register provides an up to date comprehensive listing of buildings, structures objects and sites that have received local, state or national designations based on their historical or archaeological significance.

Summary of Receiving Waters and Impairments

Surface Water Quality Standards (SWQS) are provided by the Massachusetts Department of Environmental Protection (DEP). They are determined for a water body's designated use. The SWQS designate the uses that surface waters are protected for, and an assessment is performed to determine if the designated uses are met by the water bodies. The use is not assessed in instances when there is insufficient data or information. Assessment information is maintained by the DEP in the Water Body System (WBS) database, which is updated every two years. Designated uses include:

· Aquatic Life · Fish Consumption · Primary Contact Recreation (Swimming) · Secondary Contact Recreation (Boating) · Aesthetics

The aquatic life use is supported when suitable habitat is available in the water body to sustain a native and diverse aquatic environment. Impairments to the aquatic life use can result from anthropogenic sources of pollution. Organic enrichment, flow and habitat alteration, sedimentation (habitat destruction), and whole effluent toxicity are potential causes of water body impairment for this use.

The fish consumption use is met when pollutant concentrations are acceptable for edible marketable fish or shellfish or for the use of recreationally caught fish or other aquatic life for human ingestion.

The primary contact recreational use is any activity that involves prolonged contact with the water with a significant risk of ingestion. Activities include swimming, diving, water skiing, and wading, among others. The secondary contact recreational use includes any activity with incidental water contact including boating, fishing, and other activities.

The aesthetic use is supported when water bodies do not contain objectionable deposits, floating debris, scum, or other matter, which produces offensive odors, colors, taste or turbidity or produces noxious aquatic life.

Total Maximum Daily Loads (TMDLs) are the amount of a pollutant allowed to be discharged into a water body per day to assure attainment of the SWQS. The sum total of all pollutant load allocations cannot exceed the total maximum allowable pollutant load calculated for the water body.

Impaired water bodies are those that are not expected to meet the SWQS due to specific pollutants or stressors. However, numerical data is not available for every pollution indicator, so best available guidance in the literature may be applied. Not all water bodies are assessed; many small and/or unnamed water bodies are currently not assessed.

According to the Massachusetts Year 2014/2016 Integrated List of Waters, there are five categories for water quality assessment.

6 Stormwater Management Program June 2019 Taunton, Massachusetts

· Category 1 — Waters attaining all designated uses · Category 2 — Attaining some uses; other uses not assessed · Category 3 — No uses assessed · Category 4A — TMDL is completed · Category 4B — Impairment controlled by alternative pollution control requirements · Category 4C — Impairment not caused by a pollutant – TMDL not required · Category 5 — Waters requiring a TMDL

The City of Taunton has seventeen (17) impaired water body segments within the City limits, however only fifteen (15) receive flow from the MS4. Table 1 summarizes these water bodies and the associated impairments and TMDLs requiring action as described in the Permit and this SWMP based on the approved Massachusetts Year 2014 Integrated List of Waters and the proposed Massachusetts Year 2016 Integrated List of Waters.

These impaired water bodies and the MS4 areas tributary to them can be found on the storm sewer system map included in Appendix D, as well as part of the IDDE report, which is located in the IDDE Plan.

Appendix H of the Permit identifies specific requirements for water bodies that are Water Quality Limited in five categories of impairments (Nitrogen, Phosphorus, Bacteria/Pathogens, Chloride and Solids, Metals or Oil and Grease). These requirements apply to water bodies and their tributaries that do not meet applicable water quality standards, including but not limited to waters listed in category 5 and waters without an EPA approved TMDL.

Taunton WQLW Impairment(s) Nitrogen Phosphorus Appendix F of the Permit identifies specific requirements for discharges to impaired waters or their tributaries with an approved TMDL.

DISCHARGES

EPA has written the Permit to meet Massachusetts state water quality standards. Antidegradation provisions at 314 CMR § 4.04 are part of the current EPA-approved water quality standards for Massachusetts. As such, the Permit requires compliance with 314 CMR § 4.04 and increased discharges from MS4s remain subject to 314 CMR § 4.04.

Increased Discharges Authorization

The Massachusetts Stormwater Management regulations, current site development review practices and new stormwater regulations drafted by the City prohibit increased discharges. They all require that any new development or re-development (including new impervious area) is subject to the Post-Construction Stormwater Management requirements, which include infiltration standards that are intended to mimic pre-development conditions. New impervious areas require the implementation of best management practices (BMPs). In a case where these conditions cannot be met, authorization for an increased discharge may be required.

All listed water bodies in the City are identified as impaired waters on the proposed Massachusetts Year 2016 Integrated List of Waters. As discussed previously, this SWMP incorporates the required actions outlined in Appendix F and H of the Permit aimed at decreasing pollutants causing impairments to those water bodies. These actions combined with the implementation of post construction stormwater requirements will decrease the overall pollutant loading to all receiving waters over time. Town compliance with these requirements of the Permit, including all reporting and documentation, demonstrates no net increase in pollutant loading from the MS4.

Discharges to TMDL or Water Quality Limited Waters

As previously noted, most discharges in the City are to either TMDL or Water Quality Limited Waters. Table 1 highlights the TMDL(s) and/or Water Quality Limitations for each of Taunton’s listed water bodies. The MS4 area tributary to each water body is subject to the TMDL and/or Water Quality Limited Waters requirements (described previously) based on that water body’s stormwater related impairments. A map of the MS4 discharge locations (i.e. outfalls and interconnections), the MS4 area tributary to each receiving water and the TMDL and/or Water Quality Limitation triggering additional requirements to reduce pollutant loading and protect water quality can be found in the IDDE Plan.

14 Stormwater Management Program June 2019 Taunton, Massachusetts

IMPLEMENTATION OF MINIMUM CONTROL MEASURES

The 2016 MS4 Permit states that the permittee shall continue to implement their 2003 MS4 SWMP while updating it pursuant to meet the requirements of the new permit. Upon adoption, this new SWMP supersedes the 2003 SWMP and all related deadlines and expectations. As indicated in the 2003 and 2016 MS4 permits, the permittee shall reduce the discharge of pollutants from the MS4 to the maximum extent practicable (MEP) using these 6 minimum control measures (MCM): 1. Public Education and Outreach 2. Public Involvement and Participation 3. Illicit Discharge Detection and Elimination (IDDE) Program 4. Construction Site Stormwater Runoff Control 5. Stormwater Management in New Development and Redevelopment (Post-Construction Stormwater Management) 6. Good House Keeping and Pollution Prevention for Permittee Owned Operations

17 Stormwater Management Program June 2019 Taunton, Massachusetts

BMP 1-1 Conduct an Annual Household Hazardous Waste Collection Day

Over the last twenty years the Taunton Wastewater Treatment Plant has sponsored an annual Household Hazardous Waste (HHW) Collection Day and will continue to do so during the month of April each year during the permit term. The City will use the event as a vehicle to raise awareness throughout the community about the potential impacts hazardous household materials have on water quality when they are not stored or disposed of properly. The event will continue to take place at the City's Wastewater Treatment Plant on West Water Street, allowing residents a convenient location and safe method to properly dispose of household hazardous waste. In addition, residents can also drop-off household hazardous materials at the landfill on 330 East Britannia Street throughout the year.

The DPW periodically conducts a mass mailing of a brochure entitled Taunton Recycling Information. This brochure is updated annually and provides the public with information on how they should dispose of trash and recyclables, tips for composting, and procedures for disposal of household hazardous wastes. This information publicizes the HHW Collection Day event and the ability for residents to conduct special drop-offs of their household hazardous materials at the East Britannia Street landfill. Additionally, the HHW Collection Day event will be advertised in the form of a press release to the Taunton Gazette which will include the details of the event, a listing of the materials that will be accepted, proper methods of storing household hazardous wastes and what impacts these hazardous materials can potentially have on the environment if they are improperly disposed.

The Taunton Department of Public Works also uploads all the above information on the City’s website. This page currently contains information and links to other web sites that contain information about household hazardous waste. A resident can learn about the different classifications of household hazardous waste materials, their detrimental effects, alternatives to HHW, how to properly dispose of HHW and much more. The DPW will ensure that this information is maintained on the web site as well as include specific information about the HHW Collection Day event. The HHW Collection day will also be advertised on the City's public cable access channel in order to disseminate the information to as many residents as possible.

BMP 1-2 Distribute a Series of Educational Flyers

A component of the City's public education efforts will include the development of a series of educational flyers. These flyers will be distributed as inserts in the Taunton Municipal Lighting Plant (TMLP) bill on a biennial basis. The flyers are to be both an educational and motivational tool, increasing public awareness of stormwater issues and teaching citizens about their influence on stormwater quality and flow.

Every other year, under the guidance of the Conservation Commission, the Taunton Ecology Awareness Movement (TEAM) will develop one flyer for distribution to the City's residents. The subject matter of these flyers is expected to include such topics as lawn care, water conservation, pet waste management, trash management, vehicle care and maintenance, and proper disposal of household hazardous waste materials. The flyers will provide residents with information about preventing stormwater pollution and offer incentives for changed behaviors. For example, a lawn care brochure could focus on proper fertilizing, watering, and mowing practices that would help protect water resources and save the homeowner both time and money. The flyers will be used to raise awareness among residents about what they can do to reduce stormwater pollution. The electronic version of these flyers will also be posted on the City's web page in for viewing throughout the permit term.

BMP 1-4 Promoting Water Conservation Practices for Homeowners

While the City's Water Conservation Program was originally created to help reduce the strain on Taunton Water Treatment Plant this program provides other benefits. For homes that are serviced by private on-site septic systems, practicing water conservation will reduce the amount of wastewater to be treated, therefore minimizing strain on the system and improving pollutant removal performance. For properties serviced by the municipal sewer system, a successful water conservation campaign can help reduce the frequency of sanitary sewer surcharges, reduce the load on the Taunton Wastewater Treatment Facility (tributary to the Taunton River) and reduce the need to expand the existing sewer system.

Taunton actively promotes water conservation practices to all residence throughout the year. The Water Department places reminders in the local newspapers multiple times a week during times of peak water use. The City has also posted water conservation tips on the Water Division's web page, which can be accessed at https://www.taunton-ma.gov/water-division. The Water Division will continue these practices throughout the permit term.

Primary Audience All residents and businesses

BMP 2-4 Conduct Local Water Quality Monitoring Activities

Water Quality Monitoring provides important information that helps to establish a baseline from which changes in the watershed can be measured and facilitates the indication of problem areas. The City of Taunton has contracted with a private consulting firm, Veolia Water and Waste Management, to operate and maintain the Taunton Pollution Prevention Control Facility and manage and administer a pollution prevention program. This program includes collaborating with the Taunton River Watershed Alliance (TRWA) on a volunteer watershed monitoring program.

The TRWA is a volunteer organization dedicated to protecting and restoring the Taunton River Watershed. The TRWA has a network of River Action Focus Teams (RAFT) that collect monthly samplings from sixteen sites and submit them to Veolia who performs the laboratory analysis to determine the quality of the water. The sixteen sites that were chosen for sampling cover a representative area of the City's waterways. The sites include known problem areas, areas of critical concern, and areas where no previous water quality data existed. Data from these monitoring activities was used to obtain funding from the State Revolving Fund (SRF) program to finance the sewer projects in the Watson State Pond and Lake Sabbatia areas of the City. The data has also been crucial in finding and resolving sewer system outbreaks in the City.

The collaborative monitoring project between Veolia Water and Waste Management and TRWA will continue throughout the permit term. Veolia will submit reports to the City which will use the information to screen for water quality problems, evaluate the success of the Stormwater Management Program's best management practices, and measure baseline conditions and trends.

Primary Audience Veolia Water and Waste Management, Taunton Department of Public Works (DPW), the Taunton River Watershed Alliance (TRWA), General public

Measurable Goals § Identify sampling areas. § Collect and analyze samples. § Report high fecal coliform counts to responsible parties. § Draft an Annual Water Quality Report for the City of Taunton.

Responsible Parties Taunton Department of Public Works (DPW), Veolia Water and Waste Management, Taunton River Watershed Alliance (TWRA)

Implementation Strategies This activity has been running successfully since 1997 and will continue to run throughout the permit term.

Timeline Water monitoring activities as outlined above will continue to take place on a monthly basis throughout the permit term.

Annual Evaluation Veolia will prepare and submit the annual Water Quality Report for the City of Taunton to the DPW. The DPW will summarize this report and include an assessment of the progress made towards achieving the identified measurable goals.

33 Stormwater Management Program June 2019 Taunton, Massachusetts

BMP 2-5 Sponsor Storm Drain Stenciling Activities

Stenciling storm drain inlets with a simple phrase like "Drains to River" is an effective way to identify the connection between the drain inlets and the receiving waterbodies. The purpose of the message is to raise public awareness to help deter littering and other practices that contribute to non-point source pollution. The City will partner with the Taunton Ecology Awareness Movement (TEAM) to co-sponsor a storm drain stenciling event during the permit years.

The Conservation Commission and TEAM will work together to handle logistical issues for the event. The City would be responsible for providing stencils; paints and safety materials for the activity while TEAM would organize the volunteers that will stencil the storm drain inlets. As the volunteers conduct the storm drain labeling they will also note the condition of the inlets, such as whether they are clogged with debris or show signs of dumping. There are thousands of drain inlets in the City and stenciling all of them would be costly and have less of an effect than selecting drains based on specific criteria. The DPW, Conservation Commission and TEAM will work together to identify environmentally sensitive areas, areas where illegal dumping has been recorded in the past and areas of high pedestrian traffic to be the focus of the activity.

The media coverage and publicity efforts that result from this event will help educate members of the community about the importance of environmental management. The event will be publicized via the Conservation Commission’s web page, on the local cable access channel, and in a press release to the Taunton Gazette, the Brockton Enterprise and other local papers. The press release will explain the purpose of the project, solicit volunteers for the activity, and offer tips on how citizens can reduce non- point source pollution to urban runoff by modifying certain behaviors. Participation will be encouraged from local environmental groups, neighborhood groups, homeowner's associates, school children and individuals. Similar to the Annual River Cleanup (BMP 2-2), TEAM will solicit support from local businesses in the form of charitable donations to provide materials for stenciling and a lunch for all the citizen volunteers.

BMP 3-1 Field Verify Outfall Locations

MassGIS, USGS, city records, drainage maps, and information collected via field surveys were compiled to develop the current storm drainage system map. A majority of the storm drains and outfalls maintained by the City are shown on the map; these outfalls include those that handle drainage from municipal roadways and properties as well as outfalls from any detention basins that the City currently maintains. The City is currently in the process of adding the missing components of the mapped system; these include closed storm drainage systems in newer subdivision roads and roadside ditches. All roadways, waterbodies and wetlands located within the municipal boundaries have been illustrated on the map. All named water bodies are identified, however, there are many small streams, brooks and ponds within the municipality. Throughout the permit term the City will work to field verify all the outfalls that have been identified on the outfall location map and update the map with pertinent data. The City will also work to identify municipal outfalls within the regulated area that have been overlooked and add them to the outfall location map.

The City's storm drainage map has been created in a GIS format that can be linked to an external database in order to maintain inspection and maintenance records for various components of the storm drainage system. Future efforts will involve obtaining additional GIS software licenses, GIS training for various municipal staff, and maintaining inspection and maintenance records for the storm drainage system using the GIS databases.

Measurable Goals § Develop a schedule for outfall verification and outfall identification activities. § Perform and track the outfall verification and outfall identification activities as scheduled. § Continuously update the storm drainage system map as new components are added to the municipal storm drainage system. § Updated Map (Phase I) shall be completed within two years and complete full system map (Phase II) shall be completed ten years after the effective date of permit.

Responsible Parties Taunton Department of Public Works (DPW)

BMP 3-3 Continue Septic System Management Program (SSMP)

The City of Taunton will continue to enforce a Septic System Management Program (SSMP) in order to maintain new systems and to detect and correct existing systems that have been failing. A failure of on-site disposal systems can be due to a number of cause's, including unsuitable soil conditions, improper design and installation, or inadequate maintenance practices. Approximately 60% of the housing units in the City rely on septic systems to treat sanitary waste. A large percentage of these on-site systems can be found within the watersheds of the Three Mile River, Segreganset River and Lake Rico. Identifying and eliminating failing septic systems will help control contamination of ground and surface water supplies from untreated wastewater discharges.

The City's formal SSMP will consist of (1) Performing Public Education, (2) Maintaining a Septic System Database, (3) Offering the Community Septic Management Betterment Loan Program.

Performing Public Education With each Certificate of Compliance that is issued for newly constructed and repaired septic systems the Taunton Board of Health (BOH) also distributes a public education packet. This packet includes literature about caring for a septic system, identifying a failing system, and guidance for having a Title V Inspection done. Pertinent Title V websites and telephone numbers are also listed in the packet. The BOH regularly updates the informational packets with new flyers, brochures and articles and maintains a budget for their duplication. The BOH recommends that the informational packets be passed along to the next property owners at the time of sale. These brochures are also continuously available at the BOH office.

In addition, the BOH conducts a Septic System Maintenance Workshop two times a year. During the workshop a presentation is made by a BOH representative, a DEP slideshow about septic system maintenance is shown, and informational handouts are distributed. This event is advertised in the Taunton Gazette and the Brockton Enterprise, on the local cable access channel, on the City's web page, and TWEP a local AM radio station.

Maintaining a Septic System Database Title V requires that licensed septic system pumpers submit a copy of all system pumping forms to the local approving authority, in this case the BOH, after the pumping job. This requirement allows the BOH to obtain pumping information for all septic systems in the City in order to identify failed systems. The BOH identifies these failed systems by reviewing the pumping records for systems that have been pumped out four or more times a year. Property owners with failing septic systems are then sent notices and remind them of the requirements set forth in 310 CMR 15.300 which ensure proper operation and maintenance of all systems and identification and upgrade of failed systems.

Offering the Homeowner Septic Repair Loan Program (HSRLP) The Office of Economic and Community Development currently manages the Homeowner Septic Repair Loan Program (HSRLP). This program makes loans available to Taunton homeowners who have a failed septic system and lie within City designated environmentally sensitive areas or are located within 200 feet of a body of water. The program offers a low interest loan provided through the Department of Environmental Protection (DEP) Water Pollution Abatement Trust that can be paid back over ten years. The loan is secured as a betterment assessment against the homeowner's property and is recorded with the Registry of Deeds as a lien on the property. Loan amounts cover all costs associated with septic system repair, replacement or upgrading or connecting to the municipal sewer system where available.

Measurable Goals § Track the number of septic system pumping companies licensed by the City each year. § Track the number of septic system installers that are licensed by the City each year. § Track the number of Certificates of Compliance issued each year. § Track the number of failed septic systems identified each year and action taken. 43 Stormwater Management Program June 2019 Taunton, Massachusetts

§ Track the number of property owners that participate in the HSRLP. § Host the Septic System Maintenance Workshop. § Track the number of attendees at each Septic System Maintenance Workshop.

Responsible Parties Taunton Board of Health (BOH), Mayor's Office of Community Development (MOCD), Conservation Commission

Implementation Strategies The BOH will update the septic system database on a regular basis and review the data to identify failed septic systems and septic systems requiring routine maintenance. Property owners will be contacted by the BOH to inform them of a failing system or one requiring maintenance The BOH will continue to produce the septic system informational packets and provide one with every Certificate of Compliance issued as well as continue to have the packets available at the BOH office. Twice a year the BOH will hold a Septic System Management Workshop and advertise it as outlined above. The MOCD will continue to offer and manage the HSRLP.

Timeline The BOH will continue to provide public education materials and maintain the septic system database as outlined in the BMP description throughout the permit term. The BOH will also host the Septic System Maintenance Workshop every fall and winter throughout the five year permit term. The MOCD will offer the HSRLP to Taunton residents throughout the permit term.

Annual Evaluation The BOH will prepare a summary of the SSMP that includes an assessment of the progress towards achieving the identified measurable goals.

BMP 3-4 Continue Sewer Separation Management Program

The City of Taunton is looking to keep extraneous flows from entering the sanitary sewer system and minimize the possibility of sanitary sewer overflows. Overflows can occur when the flows into the system exceed the design capacity resulting in back-ups into basements and streets or streams. Failures in the City's sanitary sewer system are attributed to deterioration caused by age, or poor installation techniques or having been inadequately sized. The City also suspects that a significant number of buildings in the older areas of the City may have connections from their roof leaders, sump pumps and yard drains to the sanitary sewer system. These connections could overload the sanitary sewer system due to the inability of the sewer pipes to handle the extraneous flows resulting from wet weather discharges because the sewer pipes were not originally designed to convey wet weather flows

Measurable Goals § Evaluate the recommendations made in the Comprehensive Wastewater Management Study and develop a plan to perform the recommended activities. § Track the City's sanitary sewer capital improvement projects conducted.

Responsible Parties Taunton Department of Public Works (DPW)

Implementation Strategies The City is tracking the sanitary sewer capital improvement projects conducted and will continue to implement projects that separate the sanitary and stormwater sewer systems.

Timeline The City will continue a series of capital improvement projects to address the separation of the sanitary and stormwater sewer systems. Providing that funding is available, a variety of projects will be conducted throughout the permit term.

Annual Evaluation The DPW will prepare a summary that includes an assessment of the progress towards achieving the identified measurable goals.

BMP 4-2 Site Inspections and Enforcement of Erosion and Sediment Control Measures

During construction, erosion and sedimentation control (ESC) measures are rendered ineffective if they are not installed or maintained properly. In order to ensure the effectiveness of construction site ESC measures, regular inspections must be conducted. Inspections will be conducted at various stages of the construction process including clearing and grubbing, rough grading, building/roadway construction, finish grading and final stabilization. ESC Inspection Forms will be developed to assist the inspector in documenting the ongoing inspection and maintenance ESC Inspection Forms will identify the project site and the stage of construction.

The Inspections Section of Article IV (Required Improvements) of the City of Taunton Rules and Regulations Governing the Subdivision of Land requires that the quality of materials and methods of installation of the proposed improvements within a subdivision be inspected. Five inspections are required and the regulation outlines specific purposes for each inspection. Projects that are regulated under the Rules and Regulations governing the Subdivision of Land will also be covered by the City’s Stormwater Ordinance and therefore will require ESC measures to be inspected and maintained. Inspection of the ESC measures installed on subdivision projects will be incorporated into the series of five-inspections that are currently conducted during these inspections an ESC Inspection Form will be completed and then submitted to the Planning Board. The inspection fee outlined in sub-section 427 of Article IV will cover these inspection services.

Inspection of the ESC measures for all other regulated projects will occur as outlined in the City’s Stormwater Ordinance. The Conservation Commission, with assistance from the Engineering Department, will inspect the ESC measures and charge the developer responsible a fee to cover the cost of scheduling and conducting these inspections.

Consultation Code: 05E1NE00-2017-SLI-0465 December 14, 2016 Event Code: 05E1NE00-2017-E-00644 Project Name: Taunton MS4 Permit Area

Subject: List of threatened and endangered species that may occur in your proposed project location, 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, 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 if you 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)(1) 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. 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.htm; http://www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/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.

9/19/2016 11:25 AM IPaC v3.0.9 Page 6 IPaC Trust Resources Report Wetlands

Wetlands in the National Wetlands Inventory Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District.

DATA LIMITATIONS The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis.

The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems.

Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.

DATA EXCLUSIONS Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.

DATA PRECAUTIONS Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.

Wetland data is unavailable at this time.
