Minor edits and revisions are reviewed and made on an ongoing basis. Storm water mapping is archived in GIS based data layer available to Town staff and public electronically.

PY 2 (2014-2015) Yarmouth’s stormwater infrastructure is 100% mapped as noted above. Edits and revisions continue to be made on an ongoing basis as required and are archived in the GIS based data-layer for stormwater infrastructure. A sample of Yarmouth’s mapping is included in the appendices.

Page 16

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

PY 3 (2015-2016) through PY 8 (2020-2021) Yarmouth’s stormwater infrastructure is 100% mapped as noted above. Edits and revisions continue to be made on an ongoing basis as required and are archived in the GIS based data-layer for stormwater infrastructure. The live mapping may be viewed via the ArcGIS mapping portal as noted above.

MEASURABLE GOAL 3.1.3 – Map Pipes By the end of the Permit Year 5 (June 30, 2018), and each permit year thereafter, the permittee will: a. Update the watershed-based storm sewer system infrastructure map to show all new connecting surface and subsurface infrastructure depicting the direction of in-flow and out-flow pipes,

PY1 (2013-2014) All infrastructure mapping is complete Town wide except for normal updates and as-built work; which is currently on-going. It is anticipated that storm drainage projects nearing completion in the reporting period will incorporated into the mapping system during the next permit period.

PY2 (2014-2015) All infrastructure mapping is complete Town wide except for normal updates and as-built work; which is currently on-going. It is anticipated that storm drainage projects nearing completion in the reporting period will incorporated into the mapping system during the next permit period.

PY3 (2015-2016) All infrastructure mapping is complete Town wide except for normal updates and as-built work; which is currently on-going. It is anticipated that storm drainage projects nearing completion in the reporting period will be incorporated into the mapping system during the next permit period.

PY4 (2016-2017) through PY 8 (2020-2021) All infrastructure mapping is complete Town wide except for normal updates and as-built work; which is currently on-going. It is anticipated that storm drainage projects nearing completion in the reporting period will be incorporated into the mapping system during the next reporting period. Also, it should be noted that all storm drainpipes include flow direction arrows.

b. Ensure each catch basin will be uniquely identified to facilitate control of potential illicit discharges, and to ensure proper operation and maintenance of the structures.

PY1 (2013-2014) through PY 8 (2020-2021) Catch basins throughout Town have unique identifiers assigned. For PY8, several catch basins that were added to the GIS from the field required assignment of IDs after the fact in the desktop application. The IDs were assigned in August 2021.

c. For each outfall, the following information will be included: type, material, and size of conveyance, outfall or channelized flow (e.g. 24” concrete pipe); the name and location of the immediate surface waterbody or wetland to which the stormwater runoff discharges (or, if an outfall does not discharge directly to a named waterbody, the name and location of the nearest named waterbody to which the outfall eventually discharges.)

Page 17

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

PY1 (2013-2014) 385 Outfalls are mapped; all of them have material and size fully documented on the maps. The name of receiving water for each is included on map’s attribute table. Additionally, the Town has moved from a paper-based inspection protocol to a fully electronic inspection format. The Town has purchased a ruggedized tablet computer with GPS capability that is used to perform outfall field inspections, outfall characterizations and GPS locating and other data acquisition activities for our system mapping. This new tool has significantly increased the Town’s productivity; allowing staff to perform more inspections in less time. It is anticipated that during the next permit year the Town will move the mapping data files to the cloud to allow more flexibility in the mapping use.

PY 2 (2014-2015) Actions performed for this BMP: During the permit year, the Town worked collaboratively across the Public Works Department, Waste Water Department, Engineering Department and the Yarmouth Community Services (YCS) to move our GIS system to a cloud-based system. This allows a much more flexible use of technology among office staff as well as field operators. With our mapping data, including storm drain system and sewer system as well as all other data layers in the cloud, the mapping can be accessed in real time by field staff using 4G devices rather than paper maps. For example, Public Works staff can use a smart phone to pull up the maps that show all attributes of the map, such as catch basins, pipe location and direction of flow, outfalls, etc. Any data that is included in our mapping is accessible via the device and in real time along with the GPS locator. For example, as Public Works performs catch basin cleaning, the data is entered directly into electronic forms and immediately uploaded to the cloud system making it available to all GIS map users. It is anticipated that in the 4th quarter of 2015 read only map data will be made available to the public through the Town’s website.

PY 3 (2015-2016) Actions performed for this BMP: During the permit year the Town implemented its ArcGIS online mapping portal that allows public viewing of the infrastructure map as noted above. During the permit year the Town continued to utilize this powerful mapping program to manage our infrastructure Town wide as described above. It is interesting to note that the Town mapping portal has been viewed nearly 2,700 times since it was rolled in the fall of 2015. While it is anticipated that not all of these hits were for viewing the infrastructure layers, it is clear that the site is providing significant benefit to the public.

PY 4 (2016-2017) Actions performed for this BMP: During the permit year the Town continues to support its ArcGIS online mapping portal that allows public viewing of the infrastructure map as noted above. During the permit year the Town continued to utilize this powerful mapping program to manage our infrastructure Town wide as described above. It is interesting to note that the Town mapping portal is experiencing substantial increase in use by the public; with hits approaching tens of thousands per year. While it is anticipated that not all of these hits were for viewing the infrastructure layers, it is clear that the site is providing significant benefit to the public.

PY 5 (2017-2018) Actions performed for this BMP: During the permit year the Town continues to support its ArcGIS online mapping portal that allows public viewing of the infrastructure map as noted above. During the permit year the Page 18

Town continued to utilize this powerful mapping program to manage our infrastructure Town wide as described above. It is interesting to note that the Town mapping portal continues to experience substantial use by the public; with hits approaching tens of thousands per year. While it is anticipated that not all of these hits were for viewing the infrastructure layers, it is clear that the site continues to provide significant benefit to the public.

PY 6 (2018-2019) Actions performed for this BMP: During the permit year the Town continues to support its ArcGIS online mapping portal that allows public viewing of the infrastructure map as noted above. As noted in Measurable Goal 3.1.1, the Town conducted a review of all ditch outfalls based on the Maine DEP audit. In addition, the Public Works Department began conducting a review of all outfalls because it was identified that some outlets were being identified as outfalls, when in fact they were just a culvert that outlet to a Town Ditch. As a result, some outfalls were removed from the system, and some were added. The total number of outfalls mapped as of 6/30/2019 was 382 (including ditch and piped outfalls).

PY 7 (2019-2020) to PY8 (2020-2021) Actions performed for this BMP: During the permit year the Town continues to support its ArcGIS online mapping portal that allows public viewing of the infrastructure map as noted above.

d. Add to the mapping system all septic systems meeting the requirements of BMP 3.5 as required.

PY1 (2013-2014) No activities required during this permit year.

PY 2 (2014-2015) No activities required during this reporting period.

PY 3 (2015-2016) Actions performed for this BMP: The Town has added a layer to the GIS mapping datasets that identify septic systems in the highest priority watershed (Brickyard Hollow) that are twenty (20) years old or greater and which may discharge to the MS4 system should they fail. It should be noted that this data layer is available to Town staff but is not accessible through the public map viewer.

PY 4 (2016-2017) Actions performed for this BMP: As noted in the prior Permit Year, the Town has added a layer to the GIS mapping datasets that identify septic systems in the highest priority watershed (Brickyard Hollow) that are twenty (20) years old or greater and which may discharge to the MS4 system should they fail. It should be noted that this data layer is available to Town staff but is not accessible through the public map viewer. Inspection reports are currently performed in paper format, but it is anticipated this activity will be converted to an electronic process in the next Permit Year.

PY 5 (2017-2018) Actions performed for this BMP: As noted in the prior permit years, GIS mapping datasets identify septic systems in the highest priority watershed (Brickyard Hollow) that are twenty (20) years old or greater and which may discharge to the MS4 system should they fail. It should be noted that this data layer is available to Town staff but is not accessible through the public map

viewer. Inspection reports are currently performed in paper format. No additional inspections were performed in the Permit Year.

PY 6 (2018-2019) through PY 8 (2020-2021) – No work required to be completed this year, but the GIS mapping data sets continue to include the Brickyard Hollow septic systems as in prior years.

BMP 3.2 –NON-STORMWATER DISCHARGE ORDINANCE Responsible Party: Town Engineer

MEASURABLE GOAL 3.2.1 – The Non- Stormwater Discharge Ordinance has been adopted and implemented in 2008. By Permit Year 4 (June 30, 2017) the Town will review the existing ordinance to ensure it is adequately addressing any stormwater discharges that may cause or contribute to water quality violations and shall amend the ordinance, if required, by the end of Permit Year 5 (June 30, 2018).

PY 1 (2013-2014) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May 2008.

PY 2 (2014-2015) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May of 2008.

PY 3 (2015-2016) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May of 2008.

PY 4 (2016-2017) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May of 2008.

PY 5 (2017-2018) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May of 2008.

PY 6 (2018-2019) A Non-Stormwater Discharge Ordinance was adopted by Town Council in May of 2008. Additionally, in July of 2019 (PY7) the Town Council updated the Ordinance to reference the correct definition of Urban Area per MDEP request.

PY 7 (2019-2020) – PY8 (2020-2021) No work required to be completed, the Non-Stormwater Discharge Ordinance is still in effect.

MEASURABLE GOAL 3.2.2 – Reporting – Document any illicit discharge incidents and municipal enforcement actions as a result of the adopted ordinance will be included in annual reports to DEP each year of the permit.

PY 1 (2013-2014) No illicit discharge incidents have occurred in 2013-2014.

PY 2 (2014-2015) During the reporting period there were two (2) illicit discharge incidents in Yarmouth. The first incident was anonymously reported to the Code Enforcement Officer (CEO) by a concerned resident who witnessed a commercial vehicle washing business discharge wash water across a parking lot to a Town catch basin (CB ID 205-50). The Town Engineer immediately responded to the incident and met with the operator. After educating the operator

Page 20

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21) regarding the Non-Stormwater Discharge Ordinance requirements, the operator agreed to wash only while using a reclamation mat that allows the capture of wastewater for discharge to the public sanitary sewer. No subsequent reports from this operation have been received and subsequent site visits by Town staff have seen no recurrence of this activity.

The second incident was reported to the Town Engineer by Public Works staff who noted soap suds in a catch basin (CB ID 42-10). The Town Engineer responded to the site and after investigating the incident determined that the suds were a result of residential car washing activities. While not prohibited, the Town Engineer did discuss the activity with the resident performing the car washing and suggested alternatives such as washing the vehicles on the lawn rather than the driveway. The resident was unaware of the impacts of car washing on the environment and agreed to wash vehicles on the lawn rather than in the driveway.

Copies of the Illicit Discharge Incident Tracking Sheet for these incidents are available on request.

PY 3 (2015-2016) Actions performed under this BMP: During the reporting year there were four (4) incidents, that while not actual reportable Illicit discharges, were addressed in some fashion by the Town. The first incident pertained to the sinking of a private boat off Littlejohn Island, adjacent to the Littlejohn Island Town Wharf. The Yarmouth Harbormaster responded to the incident and was able to contain and clean up a minor fuel oil spill using the on-board spill kit. The US Coast Guard also responded to this incident. While the discharge did not impact the MS4 infrastructure, it was quickly and safely addressed by the Harbormaster using the spill kit required under the Town’s O&M plan.

The second incident was an approved discharge of a residential swimming pool on or about November 19, 2015 at 85 Village Brook Drive. The property owner coordinated with the Town Engineer to provide the required de-chlorination and extended flow path before the water was discharged to the receiving water. The pool water was tested three times and no chlorine was detected. The water was then pumped through a one (1) inch diameter pump discharging to a grassed swale traveling 80 feet to the road gutter line where it traveled about 90 feet until it entered a Town catch basin. The water then traveled about 350 feet through the drain piping system before entering the receiving water. This discharge was allowable under the NPDES MS4 General Permit since there was no chlorine present.

The third incident involved a Town owned property on Cousin’s Island. MDEP and Marine Resource staff identified this seasonal property as potentially suspect for a failing septic system as part of a regular review of the bay. While no illicit discharge was identified, it was noted by MDEP field staff that the septic tank was non-standard, and the leach field appeared to be undersized in addition to being quite old. The Town voluntarily replaced the existing system with a new sub-surface wastewater disposal system per Maine Plumbing Code requirements. The new system installation was completed on December 9, 2015.

The final incident pertained to a regular inspection of Town Hall on May 3, 2016. No illicit discharge occurred, however the potential for one to occur was eliminated. It was noticed that the contracted dumpster a Town Hall was missing a plug. The plug was replaced by the waste hauler within one (1) week.

PY 4 (2016-2017) Actions performed under this BMP: During the reporting period there were three (3) incidents that occurred, two (2) of which could be considered illicit discharges that were discovered and addressed by the Town. The first incident was reported by a Town Page 21

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21) employee to the Town Engineer on December 2, 2016 and consisted of commercial vehicle washing activity by a private school that was discharging to the Town storm drain system. The Town Engineer met with the vehicle maintenance supervisor for the private school and was able to achieve voluntary compliance with the Code of Ordinances. The supervisor agreed to cease washing activities on the school campus and will transport all buses and equipment to a commercial was facility in another community. The Town has continued to monitor this site for compliance and has noted no repeat activity by the private school. The issue was resolved on December 6, 2017.

The second incident was the discovery of a sewer service/storm drain cross connection. On May 26, 2017, during the investigation of a potential natural gas main cross bore of a sewer service, it was discovered that the service was illegally connected to the storm drain. The Yarmouth Sewer Department was immediately notified and on June 1, 2017 the sewer service was removed from the storm drain main and connected to the sanitary sewer main. It is interesting to note that the inspections for the affected outfall pipe did not show any indicators of the cross connection.

The third incident occurred on April 27, 2017 and consisted of a petroleum spill of 15 to 20 gallons of gasoline. The spill was contained and cleaned up by Yarmouth and MDEP first responders. No product was discharged to the Town’s MS4.

PY 5 (2017-2018) Actions performed under this BMP: During the reporting period there were two (2) incidents that occurred, one that could be considered an illicit discharge, (a serious one at that), that was discovered by the Town. The first incident was reported by Yarmouth Public Works staff when they noticed a trial of hydraulic fluid on East Main Street and traced the leak to a piece of construction equipment owned by a local contractor. Public Works responded per the SOP and cleaned up the spill. No petroleum product was discharged to the Town’s MS4.

The second incident occurred on April 2, 2018. This incident was reported by a Public Works employee who noticed the apparent discharge in the Town’s hockey pond adjacent to US Route 1 and the North Yarmouth Academy (NYA) Travis Roy Arena. While performing routine deicing operations in the NYA arena, the slush ice, which was contaminated with ice paint was pushed to the Zamboni ice melt pit and allowed to melt and drain through the outlet. The ice melt pit was illegally connected to the site storm drain system that discharged to the Town’s hockey pond. Once reported, Public Works, Code Enforcement and NYA staff as well as the Stormwater Coordinator immediately responded to stop the discharge. It is important to note that no discharge to waters of the US occurred since all contamination was contained within the Town’s pond and then conveyed to the wastewater treatment plant with MDEP’s authorization. The Town issued a Notice of Violation and required NYA to complete mitigation work to ensure that the discharge physically cannot occur in the future. Additionally, NYA was required to develop SOP’s to ensure proper O&M of the newly installed controls, provide training on the SOP’s to all employees and for all NYA grounds and facilities employees, including senior management staff, to receive stormwater awareness training provided by Yarmouth’s Town Engineer. NYA successfully completed their mitigation plan. It is also important to note that in this case municipal employee stormwater awareness training likely played a critical role in having this discharge noticed, identified as wrong and reported to the right people to address. The employee who noticed the discharge had received annual awareness training just a couple of weeks previously. I think this is a very good indication that the training is critical and effective.

PY 6 (2018-2019) Actions performed under this BMP: During the reporting period, four illicit discharges were investigated: The first incident was an apparent soapy discharge identified during outfall inspections. The Stormwater Coordinator authorized upstream inspections of the system and inspected two suspect homes for illicit connections. None were identified. The area continues to be monitored.

The second incident was a report of a resident dumping paint into a catch basin (associated with outfall 6-025-000). The Stormwater Coordinator responded with Public Works who cleaned the basin. The Stormwater Coordinator issued a verbal warning to the homeowner who committed never to do this again.

Two additional incidents were identified during PY6, and investigated early in PY7, and so are being reported on. During ditch outfall mapping, two areas were identified as having high nutrient condition and were sampled for fecal coliform. Because the investigation of the drainage area shows the ditch outfalls receive water from wooded intermittent streams, the fecal coliform results were low, and no optical brighteners or ammonia were present, the high nutrient condition is likely because of naturally occurring bacteria. No further action is planned for these areas, except for regular outfall and ditch monitoring.

An additional area was initially thought to be a potential illicit discharge because the inspector observed a sheen on the water associated with outfall 5-016-001 (a private 4-inch line coming from a residence) and 5-016-003 (a road culvert outlet that receives the discharge from the private line). The inspector spoke with the resident during the inspection who noted they have a sump pump in their basement, which was the source of the water. The resident stated they do not have any oil discharging from their sump pump. The sheen was determined to be associated with groundwater that had a high iron content, and the iron was oxidizing as it hit the air and was discharged through the sump pump. There was no odor associated with these outfalls, and no indication of illicit discharged upon re-inspection. They have been returned to regular monitoring.

PY 7 (2019-2020) Actions performed under this BMP: During the reporting period, three illicit discharges were investigated:

a. PY7-001: On 8/21/2019 a citizen complaint along with photo documentation was received notifying the Town that concrete washout was being discharged to a drainage swale adjacent to Hancock Lumber by a subcontractor of a construction firm. Hancock Lumber was issued a NOV on 9/11/2020 and was required to pay a fine, develop and implement a site-specific stormwater O&M plan and provide training for all site staff on the Plan. The required mitigation items were satisfactorily completed by Hancock Lumber on January 17, 2020. b. PY7-002: On December 20, 2019, a Parks Department snow blower broke through the ice at the Town Skating pond during clearing operations. When retrieving the machine, a tire bead failed, and the calcium chloride tire ballast leaked onto the ice and into the pond. The material was cleaned up with absorbent pads by the Parks crew. No impact to waters of the State occurred since the material was contained in the skating pond. c. PY7-003: On March 20, 2020 Yarmouth PD received a report of a carpet cleaning company discharging water from their operations to a parking lot. PD responded and curtailed the activity. The effluent from the discharge was conveyed to and captured by an upland area and did not impact waters of the

Page 23

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

State. The vendor was educated that this discharge is not allowed, and the vendor voluntarily complied.

PY 8 (2020-2021) Actions performed under this BMP: During the reporting period, one potential illicit discharge was investigated:

a. The Town received an email complaint about possible wash water discharge to a gutterline along Route 1. Upon investigation, the water was uncontaminated potable water from an ice cream machine that was backing up. No NOV was issued. Also, based on public comments provided on the Town’s Draft 2022 Stormwater Management Plan, the Town sampled two outfalls to the Royal River for bacteria and did not find evidence of any illicit discharges. The data was shared with the DEP in assisting with the response to comments.

BMP 3.3 – DRY WEATHER OUTFALL INSPECTION PROGRAM.

MEASURABLE GOAL 3.3.1 – In Permit Years 1-7, continue to use existing IDDE Outfall Standard Operating Procedure (SOP) to conduct annual dry weather outfall inspections in the sub- watersheds within the remaining Urban Area, such that by Permit Year 5 (June 30, 2018), inspections are being conducted in all sub-watersheds of the Urban Area. Note: Inspection staff will document and make use of opportunistic inspections.

Reporting - Inspection results will be documented in a database management system or other recordkeeping system and a summary will be reported in annual reports submitted to the DEP.

Responsible Party: Public Works Director and Town Engineer

PY 1 (2013-2014) In PY 5 of the previous permit cycle, the Town commissioned an electronic data acquisition process for IDDE and ditch inspections. Currently the Town utilizes a ruggedized notebook computer to check GIS stormwater mapping dataset out and collects IDDE inspection report data (In ISWG SOP Manual format) electronically using ArcPAD Forms software. The unit has capability to input newly discovered outfalls and characterization data as well as inspection data with GPS enabled notebook computer. This new system saves tremendous time and provides for more accurate data acquisition. Efficiency of IDDE inspections has significantly increased allowing more inspections to be performed in the same amount of time. During PY 1 Public Works staff conducted 716 outfall inspections which included all sub-watersheds within the Town.

PY 2 (2014-2015) Actions performed for the BMP: The Town continues to utilize electronic data collection for the outfall inspections required under this BMP. However, with the new cloud- based GIS protocol, the ruggedized computer has been replaced with other more flexible devices, which is either a smart phone or 4G capable mini-tablet. In both cases the GIS mapping is used to locate, track and manage the inspection data. During the reporting period, Public Works staff conducted 353 outfall inspections which included all sub-watersheds within the Town.

PY 3 (2015-2016) Actions performed for this BMP: The Town continues to utilize an electronic data collection tool for the outfall inspections under this BMP as noted above in PY 2. During the reporting period, Public Works staff conducted 371 outfall inspections which included all

Page 24

A copy of the inspection data output is included in Appendix 4 and it should be noted that several columns were hidden to allow readability of the spreadsheet. However, key data columns are visible.

PY 5 (2017-2018) Actions performed for this BMP: The Town continues to utilize an electronic data collection tool for the outfall inspections under this BMP as noted above in PY 2. During the reporting period, Public Works staff conducted 294 outfall inspections which included all sub-watersheds within the Town. A copy of the inspection data output is included in Appendix 4 and it should be noted that several columns were hidden to allow readability of the spreadsheet. However, key data columns are visible.

PY 6 (2018-2019) Actions performed for this BMP: The Town continues to utilize an electronic data collection tool for the outfall inspections under this BMP as noted above in PY 2. During the reporting period, Public Works staff conducted 429 outfall inspections which included all sub-watersheds within the Town – some outfalls were inspected in both the fall of 2018 and the spring of 2019, and the outfalls at DPW (which are inspected quarterly for the SWPPP) are included in these totals. A copy of the inspection data output is included in Appendix 4 and it should be noted that several columns were hidden to allow readability of the spreadsheet. However, key data columns are visible.

PY 7 (2019-2020) Actions performed for this BMP: The Town continues to utilize an electronic data collection tool for the outfall inspections under this BMP as noted above in PY 2. During the reporting period, Public Works staff conducted 626 outfall inspections which included all sub-watersheds within the Town – some outfalls were inspected in both the fall of 2019 and the spring of 2020, and the outfalls at DPW (which are inspected quarterly for the SWPPP) are included in these totals. Though some outfalls exhibited some foam because of large discharge drops (from the invert to the ground), and iron sheens, none exhibited evidence of illicit discharges. A copy of the inspection data output is included in Appendix 4 and it should be noted that several columns were hidden to allow readability of the spreadsheet. However, key data columns are visible.

PY 8 (2020-2021) Actions performed for this BMP: The Town continues to utilize an electronic data collection tool for the outfall inspections under this BMP as noted above in PY 2.

Page 27

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

PY 2 (2014-2015) Actions performed under this BMP: No work has been completed on this BMP during the permit year. During the next reporting cycle, the Town will commence work on this BMP.

PY 3 (2015-2016) Actions performed under this BMP: During the reporting period the Town Engineer ascertained which parcels within the priority watershed (Brickyard Hollow) was served by a septic system that was twenty years old or older and had the potential to discharge to the MS4 should it fail. This was accomplished as follows:  The Brickyard Hollow watershed is served mostly by the Yarmouth sewer system and most properties are connected to the system, given the Code of Ordinances requires connection in the event of a system failure. The Town sewer map data layer was reviewed and all parcels that were not located within proximity of a private or public sewer main was flagged for further review;  This list was compared to the Town Assessor’s database against two (2) key data points, building age and whether the lot was served by the sewer system or a septic system;  Parcels that met the parameters of being more than 20 years old and were served by septic were placed on the priority list. These parcels will be further reviewed through field observation as well as a thorough map/lot file review to determine if the systems have been replaced since the initial building construction or if the parcel is served by the sewer system. This work will occur in PY 4.  Yarmouth developed a DRAFT SOP for septic system inspections in PY 3 and will implement it in PY 4.  All parcels that appear on the priority septic system list are included as a data layer on the Town’s ArcGIS infrastructure map;  A copy of the priority septic system list, which includes approximately ten (10) properties, is included in Appendix 6.

PY 4 (2016-2017) Actions performed under this BMP: During the reporting period the Town Engineer inspected all septic systems in the priority watershed per the Town SOP, which were six (6) systems. All six systems appeared to be functioning as intended and did not show signs of malfunction per the SOP. It should be noted that one inspection site appeared to be abandoned and the property owner was non-responsive to a site meeting request. However, the field inspection was performed, and no obvious malfunction was apparent. It was also determined that one suspected aging septic system has been abandoned and the building connected to the sanitary sewer. A copy of the Septic System Tracking Sheet is included in Appendix 6.

PY 5 (2017-2018) through PY 8 (2020-2021) Actions performed under this BMP: As noted above, during PY 4 the Town Engineer inspected all septic systems in the priority watershed per the Town SOP. No additional inspections were required during PY 5, 6, 7 and 8. A copy of the Septic System Tracking Sheet is included in Appendix 6.

BMP 3.6: COORDINATE WITH THE YARMOUTH WATER DISTRICT (YWD)

Coordinate with the Yarmouth Water District regarding water line and hydrant flushing to determine if either is a significant contributor of pollutants to the MS4.

Page 28

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

MEASURABLE GOAL 3.6.1 – In Permit Year 1 (July 1, 2013 to June 30, 2014), coordinate with the YWD via mail or in person to evaluate whether or not water line or hydrant flushing from potable water sources is a significant contributor of pollutants to the MS4. Evaluation will include the following action:  Provide YWD with a location map showing the extent of the municipal urbanized area and the highest priority watershed(s);  Gather information from YWD, specific to the urbanized area and priority watersheds, including the number and location of hydrants and details on waterline or hydrant flushing that outlines procedures, including how often flushing occurs, typical flow rates and duration, where the water is conveyed, what the target or actual chlorine concentrations are and what best practices are employed to prevent erosion and address potential pollutants.

PY 1 (2013-2014): The Town Engineer met in person with the Superintendent, Mr. Bob MacKinnon, as well as hydrant flushing field staff, to collect information regarding the YWD’s hydrant flushing program. The following information was discussed, collected and disseminated:  YWD was provided with Figure 2.1 Yarmouth Location Map, Figure 2.3 Yarmouth’s NPDES Phase II Stormwater Program MS4 Areas (11/19/2012); Figure 2.4 Yarmouth Watersheds and Town of Yarmouth Brickyard Hollow Subwatershed map;  YWD maintains 332 hydrants in its system;  YWD typically flushes the hydrants in their system at least once per year and may flush as frequently as twice per year as staffing allows;  As a standard operating procedure (SOP), YWD provided de-chlorination via the use of diffusers with chemical tablet de-chlorination. This SOP is implemented for all hydrants that are within 1,000 linear feet of receiving waters;  Hydrant discharge is managed through the use of diffusers or temporary energy dissipaters, such as plywood or sandbags, to protect the discharge area from erosion or by directing the discharge to areas not susceptible to erosion;  YWD typically flushes hydrants at a sufficient rate to provide scour velocities in the water mains, which will vary by main size. Additionally, YWD may operate system valves in such a way to reverse the flow in the mains to provide the desired scour at lower flow rates if possible. Flush times vary, depending on main size; but typically, is performed for as short a time as possible to achieve the desired cleaning of the main;  YWD is not required to chlorinate its source water, which is a groundwater supply, but does so voluntarily. YWD typically sets a dosage rate of 0.50 ppm at its wells, which typically results in a residual range of 0.35 to 0.10 ppm in the distribution system. As mentioned above, the District’s SOP is to de-chlorinate for hydrant flushing in areas within 1,000 feet of a receiving water;  When possible, YWD directs hydrant discharge flow to well vegetated ditches or paved shoulder areas to ensure erosion does not occur and to provide for the natural dissipation of residual chlorine. Any hydrant flow where the discharge flow path is within 1,000 feet of a receiving water is de-chlorinated as noted above;  There are some problematic hydrants that the YWD avoids flushing to ensure receiving water impacts do not occur.

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

PY 2 (2014-2015) through PY 7 (2019-2020) Actions performed under this BMP: The information reported during PY1 above is accurate.

MEASURABLE GOAL 3.6.2 – By December 30, 2014, unless otherwise approved by the Department, using available GIS or other municipal mapping information, the location of hydrants will be added to the storm sewer system infrastructure map to aid in the evaluation. The Town of Yarmouth will work with the YWD to prioritize the hydrants or water lines that have the potential to cause exceedances of the ambient water quality criterion for chlorine when discharged through the MS4. The Town of Yarmouth will request a water quality progress report that documents what BMPs are being implemented for flushing activity at the prioritized hydrants as well as the YWD testing results of the total residual chlorine for any such discharges.

PY 1 (2013-2014): The Town of Yarmouth maintains a data layer in its GIS mapping system that includes YWD hydrant infrastructure. New hydrants that are installed are added to the system as required, similar to the normal storm drain mapping program. The Town is working to complete this BMP by December 30, 2014 and will report the status in the PY2 Annual Report.

PY 2 (2014-2015) Actions performed under this BMP: As noted in the PY 1 paragraph above, the Town maintains a GIS data layer of all YWD hydrants. Using the GIS mapping, the Town identified forty-one (41) hydrants that have the potential to impact receiving water quality, should the appropriate BMP’s not be implemented by the YWD during flushing operations. These prioritized hydrants are noted in a document titled YWD Prioritized Hydrant list dated June 25, 2015 and includes the YWD Hydrant Number, Street Address of the hydrant and the receiving water and the document has been shared with both the YWD Superintendent and YWD staff responsible for flushing hydrants. In addition to this prioritized list, the Town created a GIS based field mapping application, titled MS4 Viewer, that graphically depicts not only the hydrant layer superimposed on the drainage system and aerial photo, but also depicts the priority hydrants in a different color from the non-priority hydrants. This allows YWD flushing staff to, at a glance, note if the hydrant they are working on is a priority hydrant and should receive special de-chlorination and ESC protocols to protect the receiving water from unauthorized discharge. It is anticipated that the YWD will implement a GIS based mapping system sometime during PY 3, which will allow them to use the application the Town developed for their use. In the interim, the Town Engineer will work with the YWD to help ensure flushing protocols on the priority hydrants are achieved.

PY 3 (2015-2016) Actions performed under this BMP: As noted in PY 2 above, the YWD has begun initial implementation of a GIS system to manage their infrastructure mapping. YWD flushing staff are currently equipped with 4G field tablets that allow them to access the District’s GIS mapping layers including the priority hydrant layer. This allows District staff to quickly ascertain if additional flushing measures for de-chlorination are needed for a specific hydrant that is an identified priority. A copy of the MS4 YWD Prioritized Hydrant List is included in Appendix 7. Additionally, a sample map showing the hydrant and storm drain system datasets is included in Appendix 8. Priority hydrants are shown in yellow color.

PY 4 (2016-2017) Actions performed under this BMP: As noted in PY 2 above, the YWD has continued implementation of a GIS system to manage their infrastructure mapping. YWD flushing staff are equipped with 4G field tablets that allow them to access the District’s GIS mapping layers including the priority hydrant layer. This allows District staff to quickly ascertain if additional flushing measures for de-chlorination are needed for a specific hydrant that is an Page 30

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

PY 3 (2015-2016): Actions performed under this BMP: The Yarmouth Water District forwarded to the Town an annual report dated June 13, 2016 outlining the District’s BMP’s to address chlorinated water. A copy of this report is included in Appendix 9. Generally, the District notes that SOP requires dechlorination of all flushing discharge using a Pollard LPD-250 diffuser/dechlorination device using D-Chlor (sodium sulfite) tablets. Additionally, discharge is directed to grassed areas and land areas to promote further neutralization of the chlorine residual. This protocol is for typical system residual chlorine levels averaging about 0.45 mg/L. Super chlorinated discharges, such as effluent from new main disinfection activities is either disposed of in the sanitary sewer, (with Town permission) or via a Pollard LPD-250 with a gravity fed tank of CAPTOR (calcium thiosulfate) dechlorination chemical. These methods are used for residuals of 25-50 mg/L.

In discussions with District staff, it was noted that during normal flushing operations the dechlorination diffuser resulted in a tenfold decrease in residual levels and after about ten feet of travel along pavement or grassed swale area the discharge exhibited no detectable residual chlorine level.

PY 4 (2016-2017): Actions performed under this BMP: The Yarmouth Water District forwarded to the Town an annual report dated August 31, 2017 outlining the District’s BMP’s to address chlorinated water.

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

MEASURABLE GOAL 3.6.4: If it is determined by the end of Permit Year 3, that water line or hydrant flushing is a significant contributor of pollutants to the MS4, and the Yarmouth Water District has demonstrated that it will not voluntarily implement BMPs in order to reach ambient water quality criteria for chlorine, the Town of Yarmouth will, as soon as practicable or by no later than the end of Permit Year 4 (July 1, 2016 to June 30, 2017), update their Illicit Discharge Detection and Elimination (IDDE) ordinance to allow enforcement of discharges that cause exceedances of water quality criteria.

Reporting: The annual report will include a status update on the evaluation of water line and hydrant flushing as a significant contributor of pollutants to the MS4 and an update on subsequent actions.

Responsible Party: Town Engineer

PY 1 (2013-2014): No action required in PY1.

PY 2 (2014-2015): No action required in PY2.

PY 3 (2015-2016): Actions performed under this BMP: The Yarmouth Water District (District) has voluntarily implemented a hydrant flushing SOP that clearly is intended to protect Yarmouth’s MS4 and the receiving waters from the impacts of chlorine. As noted above, all discharges are routinely dechlorinated as a matter of policy in addition to utilizing other BMP’s such as diversion to grassed and upland areas as well as maintaining very long flow paths over paved areas to ensure there is no chlorine residual impacting the receiving waters. Field testing with typical equipment used by the District have shown non-detect in discharges a very short distance away from the diffuser/dechlorinator which is not surprising given the fairly low levels of residual chlorine maintained by the District. The Town will continue to work collaboratively with the District to ensure discharges from flushing do not contribute pollution to the MS4 infrastructure and receiving waters.

PY 4 (2016-2017): Actions performed under this BMP: As noted above, the Yarmouth Water District continues to voluntarily implement a hydrant flushing SOP that is protective of Yarmouth’s MS4 and the local receiving waters. The Town has received no evidence that waterline or hydrant flushing is a significant contributor of pollutants to the MS4 and the Yarmouth Water District has continued to implement a voluntary program to ensure this remains to be the case. The Town will continue to work collaboratively with the District to ensure discharges from flushing do not contribute pollution to the MS4 and receiving waters. A copy of the District’s annual report is included in Appendix 9.

PY 5 (2017-2018): Actions performed under this BMP: As noted above, the Yarmouth Water District continues to voluntarily implement a hydrant flushing SOP that is protective of Yarmouth’s MS4 and the local receiving waters. The Town has received no evidence that waterline or hydrant flushing is a significant contributor of pollutants to the MS4 and the Yarmouth Water District has continued to implement a voluntary program to ensure this remains to be the case. The Town will continue to work collaboratively with the District to ensure discharges from flushing do not contribute pollution to the MS4 and receiving waters. A copy of the District’s annual report is included in Appendix 9.

PY 6 (2018-2019) through PY 8 (2020-2021): Actions performed under this BMP: Same as PY5

Maintenance activities, maintenance schedules, and long-term inspection procedures for structural and non-structural stormwater controls to reduce pollutants discharged from the separate storm sewers. b. Controls for reducing or eliminating the discharge of pollutants into the separate storm sewers from streets, roads, highways, municipal parking lots, maintenance and storage yards, fleet or maintenance shops with outdoor storage areas, salt/sand storage locations, snow disposal areas, and waste transfer stations. c. Procedures for disposing of waste removed from the separate storm sewers and areas listed above in accordance with all regulatory requirements (such as dredge spoil, accumulated sediments, floatables, and other debris). d. Training materials available from the EPA, State, regional stormwater groups or other organizations, Guidelines and Standard Operating Procedures for Stormwater Phase II Communities in Maine, volumes 1 and 2 and the Think Blue Maine website (www.thinkbluemaine.org).

PY 1 (2013-2014): Besides the municipal employee training that was documented in MCM 4 above, Yarmouth municipal staff took advantage of training opportunities when staffing and time allowed. Several staff took advantage of training offered by the Interlocal Stormwater Working Group (ISWG) through the Cumberland County Soil and Water Conservation District (CCSWCD) at the Maine Chapter of the American Public Works (MCAPWA) Highway Congress on June 5th, 2014. It should be noted that Yarmouth performed formal stormwater training for most Town departments including Public Works, Waste Water Department and the Parks Department during the previous reporting period and is scheduled to perform a large training segment again during the winter of 2014-2015.

PY 2 (2014-2015) Actions completed for this BMP: Besides the municipal employee training that was documented in MCM 4 above, Yarmouth municipal staff was provided stormwater awareness training on June 23, 2015 and staff from Public Works, Police, Fire, School, Parks and Sewer Departments were in attendance. Additionally, training on the new Operations and Maintenance plans was performed at this training session as well as two additional training sessions provided for the Police and Fire Departments. As noted in BMP 6.6, the Town provided third party training for the new SPCC Plan and SWPPP Plans for Public Works and the Transfer Station. Town Department Heads also received Stormwater Awareness training, similar to the training provided to Town Councilors under MCM 1 on April 1, 2015.

PY 3 (2015-2016) Actions completed for this BMP: Besides municipal training completed as part or MCM 1 and MCM 4 noted above, Yarmouth municipal staff was provided stormwater awareness training on May 4, 2016 and included twenty-eight staff from Public Works, Police, Fire, Parks and the Sewer Departments. On July 13, 2015 stormwater awareness training was provided to 14 police officers of the Police Department. An attendance list and training outline is included in Appendix 11. Additionally, on May 10 and May 19, 2016 the Town provided third party refresher training for the Town’s SPCC Plan and SWPPP for 20 Public Works, Parks and the Transfer Station employees. A copy of this training outline and attendance lists is included in Appendix 12. In general, it appears that the training is fairly effective in bringing stormwater impacts to the forefront of employee minds.

In PY 5 Yarmouth’s sweeping program began on April 10, 2018 and was completed on June 18, 2018. Typically, YPW gets started a bit earlier on sweeping, however during this Permit Year, sweeping started later due to the significant cleanup required after the large windstorm damage from October 2017. Public Works collected approximately 498 cubic yards of material that was disposed of at the Town’s permitted beneficial reuse site on East Main Street. Additionally, the Town provides extensive sweeping of the Town center before and after the Yarmouth Clam Festival.

BMP 6.4 CLEANING OF STORMWATER STRUCTURES INCLUDING CATCH BASINS

Page 58

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

MEASURABLE GOAL 6.4.1 – Each permit year the Town of Yarmouth will continue to the implement and evaluate the cleaning program, and if necessary, clean catch basins and other stormwater structures that accumulate sediment at least once every other year and dispose of the removed sediments in accordance with current State law. The Town of Yarmouth will clean catch basins more frequently if inspections indicate excessive accumulation of sediment. Excessive accumulation is defined as greater than or equal to fifty percent filled.

PY 1 (2013-2014): During the reporting period, no catch basins were cleaned. Due to the fairly long winter and late start to the spring maintenance work, Public Works crews were focusing on the priority of sweeping the Town streets, sidewalks and parking areas as soon as possible. This delayed the start of the catch basin cleaning program. Catch basin cleaning operations commenced on July 21, 2014 and ended on September 19, 2014 with 867 catch basins cleaned and 168 cubic yards of material recovered and disposed of. It should be noted that by June of 2013, 1,230 catch basins were cleaned with the remainder did not requiring cleaning. It is likely that few, if any, basins exceeded the capacity of the sumps during the reporting year and did not release sediment due to being full. It should be noted that the Town will likely implement an electronic inspection/cleaning form for the catch basin cleaning program that will help field staff track the operation.

PY 2 (2014-2015): Actions completed regarding this BMP: Catch basin cleaning operations commenced on July 21, 2014 and ended on September 19, 2014 with 867 catch basins cleaned and 168 cubic yards of material recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. Additionally, the Town implemented a GIS field application that allows Public Works staff to log cleaning and inspection reports in the field using a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected as well as captures the volume of material removed from each basin for reporting. This application has made the tracking of the cleaning operation more efficient and staff, at a glance, can note any catch basins that have not been inspected and/or cleaned.

PY 3 (2015-2016): Actions completed regarding this BMP: Catch basin cleaning operations commenced on August 12, 2015 and ended on October 15, 2015 with the onset of winter operations with 458 catch basins cleaned and approximately 223 cubic yards of material recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. Of those 458 basins, 315 were estimated to be about half full and 80 were more than half filled at the time of cleaning. The remainder of the catch basins were empty. Additionally, as noted in the prior year, the Town implemented a GIS field application that allows Public Works staff to log cleaning and inspection reports in the field using a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected. It should also be noted that during the spring of 2016 the Public Works Department removed the clamshell catch basin cleaning system from the existing truck chassis and reinstalled it on a newer truck chassis. This work was not completed until after June 30 of PY 3, which is why no catch basins were cleaned in the spring of the Permit Year. Public Works commenced catch basin cleaning with the rehabilitated truck on July 20, 2016. The volume and CB cleaning numbers since July 20, 2016 will be reported in the PY 4 report.

PY 4 (2016-2017): Actions completed regarding this BMP: Catch basin cleaning operations commenced on July 25, 2016 and ended on June 29, 2017 and continued into the PY 5 reporting period with 1,721 catch basins inspected and/or cleaned during the reporting period and approximately 835 cubic yards of material recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. Of those 1,721 basins, 1,062 were estimated to be about half full and 357 were more than half filled at the time of cleaning. The Page 59

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21) remainder of the catch basins were empty. It should be noted that no basins were reported to be bypassing sediment. As noted in PY 2, the Town implemented a GIS field application that allows Public Works staff to log cleaning and inspection reports in the field using a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected. It should also be noted that during the spring of 2016 the Public Works Department removed the clamshell catch basin cleaning system from the existing truck chassis and reinstalled it on a newer truck chassis. This work was not completed until after June 30 of PY 3, which is why no catch basins were cleaned in the spring of the 2016. Public Works commenced catch basin cleaning with the rehabilitated truck on July 20, 2016 and continued throughout PY4, which allowed for multiple cleanings of some catch basins and the associated high number of inspections and volume of grit during the reporting period.

PY 5 (2017-2018): Actions completed regarding this BMP: Catch basin cleaning operations commenced on July 6, 2017 and has continued into the current reporting period with 1,145 catch basins inspected and/or cleaned as of September 9, 2018 and approximately 460 cubic yards of material recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. It should be noted that during the Permit Year the Town submitted a sample of the catch basin sediment for testing to ensure it was acceptable to dispose of at the Town’s beneficial reuse site. Of those 1,215 basins, 792 were estimated to be about half full and 219 were more than half filled at the time of cleaning. The remainder of the catch basins were empty. It should be noted that no basins were reported to be bypassing sediment. As noted in PY 2, the Town implemented a GIS field application that allows Public Works staff to log cleaning and inspection reports in the field using a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected.

As noted in follow up questions from MDEP on the Town’s cleaning program, there is a concern that some catch basins may not be cleaned frequently enough to ensure sediment does not discharge from the MS4. To help address this issue that Town has updated our GIS inspection system to provide a graphic identifier on the Storm Drain Map that indicates catch basin’s that were half full or greater in the last inspection. By seeing graphically the problem basins, field staff can provide targeted cleaning of these specific structures early in the program and more frequently if needed. For example, when field staff starts the catch basin cleaning program, they can see the map (in real time) and target the basins that were half full or greater during the last inspection first. As the cleaning program continues, the results of each cleaning will drive the map icon color to help prioritize individual structures for early/more frequent cleaning. Basins that are empty will be the last structures to be visited and inspected. It is anticipated that this new tool will help minimize the potential for sediment by-pass from the MS4.

PY 6 (2018-2019): Actions completed regarding this BMP: Catch basin cleaning operations commenced on 5/21/2019 and has continued into the current reporting period. Between 7/1/2018 and 6/30/2019, 918 catch basins were cleaned. In Permit Year 6, approximately 102 cubic yards of material was recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. It should be noted that during the Permit Year the Town did not submitted a sample of the catch basin sediment for testing because changes to Maine DEP Chapter 418 Beneficial Re-use allow catch basin sediment to be reused as long as it does not exhibit evidence of litter or pollution. Of those 918 basins, 630 were estimated to be about half full or more than half filled at the time of cleaning. The remainder of the catch basins were ¼ full or empty. It should be noted that no basins were reported to be bypassing sediment. As noted in PY 2, the Town implemented a GIS field application that allows Public Works staff to log cleaning and inspection reports in the field using a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected. The Page 60

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21)

Town does inspect and clean most of its basins each year, and as described in PY5, uses the new ap to prioritize those basins for cleaning that were more than ½ full.

PY 7 (2019-2020): Actions completed regarding this BMP: During catch basin cleaning operations between 7/1/2019 and 6/30/2020, 981 catch basins were inspected and 508 were cleaned. In Permit Year 7, approximately 75 cubic yards of material were recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. It should be noted that during the Permit Year the Town did not submit a sample of the catch basin sediment for testing because changes to Maine DEP Chapter 418 Beneficial Re-use allow catch basin sediment to be reused as long as it does not exhibit evidence of litter or pollution. Of the 981 basins that were inspected, 119 were estimated to be about half full or more than half filled at the time of cleaning. The remainder of the catch basins were less than ½ full or empty. It should be noted that no basins were reported to be bypassing sediment. As noted in PY 2, the Town continues to track inspections and cleaning using a GIS field on a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected. The Town does inspect and clean most of its basins each year, and as described in PY5, uses the new ap to prioritize those basins for cleaning that were more than ½ full. Some of the basins were cleaned twice in PY7 (fall of 2019 and spring of 2020).

PY 8 (2020-2021): Actions completed regarding this BMP: During catch basin cleaning operations between 7/1/2020 and 6/30/2021, 1245 catch basins were inspected and 995 were cleaned. In Permit Year 8, approximately 109 cubic yards of material were recovered and disposed of at the Town’s permitted beneficial reuse site on East Main Street. Even though changes to Maine DEP Chapter 418 Beneficial Re-use allow catch basin sediment to be reused as long as it does not exhibit evidence of litter or pollution, a sample was collected and the results were 420 mg/kg Total Petroleum Hydrocarbons, below the guidance value of 500 mg/kg TPH. Of the 1245 basins that were inspected, 23 were estimated to be about half full or more than half filled at the time of cleaning. The remainder of the catch basins were less than ½ full or empty. It should be noted that no basins were reported to be bypassing sediment. As noted in PY 2, the Town continues to track inspections and cleaning using a GIS field on a tablet. The application allows management staff to track in real time which basins have been cleaned and inspected. The Town does inspect and clean most of its basins each year, and as described in PY5, uses the new ap to prioritize those basins for cleaning that were more than ½ full.

Reporting - Annual reports to DEP each year of the permit will include a status report on cleaning of stormwater structures.

BMP 6.6 – STORMWATER POLLUTION PREVENTION PLANS (SWPPP’S)

MEASURABLE GOAL 6.6.1 - The Town of Yarmouth will continue to implement SWPPPs for each applicable facility during Permit Year 1-7. In Permit Year 2 the Town of Yarmouth will ensure all facility SWPPPs meet the MSGP requirements promulgated on April 26, 2011 including visual monitoring. The Town of Yarmouth will collaborate with DEP on training programs to provide to municipal facility staff informing them on the requirements of the SWPPP and how to continue to effectively implement their plans.

PY 1 (2013-2014): Yarmouth continued to implement the SWPPP’s for each facility as required by the plan and reported in previous Annual Reports. As noted above, during the reporting period, the Public Works facility was subject to a major addition and renovation that was completed at the end of the reporting period. It is anticipated that during the early part of the PY 2 reporting period the SWPPP will be updated to reflect the current conditions of the facility and will require additional focused staff training for this facility. The new SWPPP will comply with the latest MSGP requirements. The Town has DEP approved SWPPP for Transfer Station regulated under Maine’s Industrial Stormwater Program. All compliance requirements have been met.

PY 2 (2014-2015) Actions competed for this BMP: During the reporting period, Yarmouth contracted with third party engineering firms to update the Department’s Spill Prevention, Control and Countermeasure (SPCC) Plan and the Stormwater Pollution Prevention Plan

(SWPPP) at the Public Works facility on North Road and the SWPPP at the Public Works Transfer Station on East Main Street. All site-specific plans were sealed by professional engineers licensed in the State of Maine and delivered to the respective facilities. On March 10, 2015 training was provided to all staff by Kristie Rabasca, P.E., Principal of Integrated Environmental Engineering, Inc. and author of the SWPPP’s. On October 29, 2014 SPCC plan training was provided to Public Works staff by Judd Newcomb, CG, PG, Project Manager of Credere Associates, LLC and author of the SPCC. Public Works has implemented both the SWPPP’s and the SPCC at the respective sites and are in compliance with each.

PY 3 (2015-2016) Actions competed for this BMP: During the PY 2 reporting period, Yarmouth contracted with third party engineering firms to update the Department’s Spill Prevention, Control and Countermeasure (SPCC) Plan and the Stormwater Pollution Prevention Plan (SWPPP) at the Public Works facility on North Road and the SWPPP at the Public Works Transfer Station on East Main Street. All site-specific plans were sealed by professional engineers licensed in the State of Maine and delivered to the respective facilities. On May 10, 2016 refresher training was provided to staff by Kristie Rabasca, P.E., Principal of Integrated Environmental Engineering, Inc. and author of the SWPPP’s. Public Works has implemented both the SWPPP’s and performs the required quarterly visual monitoring and quarterly site inspections. It should be noted that during the last year, the Public Works facility was converted from #2 fuel oil to natural gas for building heating. As such, two (2) 330 gallon above ground heating oil tanks were removed from the site which has brought the petroleum storage volume on site below the 1,320-gallon threshold that requires a SPCC plan.

PY 4 (2016-2017) Actions competed for this BMP: During the PY 2 reporting period, Yarmouth contracted with third party engineering firms to update the Department’s Spill Prevention, Control and Countermeasure (SPCC) Plan and the Stormwater Pollution Prevention Plan (SWPPP) at the Public Works facility on North Road and the SWPPP at the Public Works Transfer Station on East Main Street. All site-specific plans were sealed by professional engineers licensed in the State of Maine and delivered to the respective facilities. On January 26, 2017 SWPPP Inspection training was provided to staff by Robyn Saunders, P.E., trainer for the Cumberland County Soil and Water Conservation District. Public Works has implemented both the SWPPP’s and performs the required quarterly visual monitoring and quarterly site inspections. As noted in PY 3 above, the Public Works Facility no longer requires a SPCC Plan since the above ground storage volume of petroleum products is less than 1,320 gallons. SWPPP training records are located in Appendix 11 Employee Awareness Training.

PY 5 (2017-2018) Actions competed for this BMP: During the PY 2 reporting period, Yarmouth contracted with a third-party engineering firm to update the Department’s Stormwater Pollution Prevention Plan (SWPPP) at the Public Works facility on North Road and the SWPPP at the Public Works Transfer Station on East Main Street. All site-specific plans were sealed by professional engineers licensed in the State of Maine and delivered to the respective facilities. Public Works has implemented both the SWPPP’s and performs the required quarterly visual monitoring and quarterly site inspections. As noted in PY 3 above, the Public Works Facility no longer requires a SPCC Plan since the above ground storage volume of petroleum products is less than 1,320 gallons. Stormwater awareness training records are located in Appendix 11 Employee Awareness Training.

PY 6 (2018-2019) Actions competed for this BMP: During PY 6, the Town contracted with a third-party engineering firm to update the Department’s Stormwater Pollution Prevention Plan (SWPPP) at the Public Works facility on North Road and the SWPPP at the Public Works Transfer Station on East Main Street. All site-specific plans were sealed by professional Page 64

BMP 6.7 – Strategy to reduce floatables and other pollutants discharged from separate storm sewers.

MEASURABLE GOAL 6.7.1 – Prior to the end of Permit Year 3, the Town of Yarmouth will determine the projected cost and evaluate the feasibility to install floatable controls on existing catch basins in the urban area and may consider implementing Measureable Goal 6.7.2.

MEASURABLE GOAL 6.7.2 – Subject to funding and feasibility of installing floatable control, the Town of Yarmouth may begin installation of floatable control measures in selected structures in the priority watershed by the end of Permit Year 5.

PY 1 (2013-2014): No action required during the reporting period.

PY 2 (2014-2015): No action required during the reporting period.

PY 3 (2015-2016): Actions completed for this BMP: During the Permit Year, the Town developed an opinion of probable cost and evaluated the feasibility of installing floatable controls on existing catch basins in the urban area. After evaluating several technology alternatives for providing floatable control, Yarmouth selected the alternative of using The Snout Oil-Water-Debris Separator as manufactured by Best Management Practices, Inc. to perform a cost analysis for retrofit on the 1,344 true catch basins in the Urban Area. After including materials, labor, vehicle and equipment, engineering, capital outlay expense and a contingency it is estimated that the total cost to provide floatable control to each catch basin in the urban area would be approximately $1.7 million dollars. This sum equates to an approximate local tax rate increase of about $1.16 per thousand dollars of value for this single program. Given current local budget stressors and competition for scarce local dollars it is unlikely that Yarmouth could undertake this program in a single year. In PY 4 and PY 5 it is anticipated that Yarmouth may have internal dialog regarding this BMP to consider how to move forward with a floatable control program. A technical memorandum documenting Yarmouth’s Floatable Control Strategy in more detail is included in Appendix 14.

PY 4 (2016-2017): During PY 4 no funding was available to implement floatable control of the magnitude suggested in the paragraph above. However, the Town has discussed the potential of installing floatable control in two specific areas that would clearly benefit from this BMP if Page 65

Yarmouth Stormwater Discharge Permit 2013–2022 Year 8 Annual Report (7/1/20 – 6/30/21) funding is available. The Town anticipates working toward addressing these to selected sites in PY 5 depending on funding levels.

PY 5 (2017-2018): During PY 5 no funding was available to implement floatable control of the magnitude suggested in the paragraph above. However, as noted previously the Town has discussed the potential of installing floatable control in two specific areas that would clearly benefit from this BMP if funding is available. Unfortunately, in PY 5 funding was not available to move forward with floatable control. It is hopeful that some work on this BMP can be implemented in the spring of 2019.

PY 6 (2018-2019) to PY8 (2020-2021): As noted in PY 5, during PY 6, PY 7, and PY 8, no funding was available to implement floatable control of the magnitude suggested in the paragraph above. However, as noted previously the Town continues to discuss the potential of installing floatable control in two specific areas that would clearly benefit from this BMP if funding is available.

Reporting – Annual reports to DEP will include the status on Measureable Goal 6.7.1 and 6.7.2.

ISWG Permit Year 8 (2020‐2021) Summary of Minimum Control Measures 1 & 2

Permit Year 8 (PY8) Summary of Minimum Control Measures 1 & 2 The following is a summary of work facilitated by the Cumberland County Soil & Water Conservation District (CCSWCD) on behalf of the Interlocal Stormwater Working Group (ISWG). The 2013 MEPDES MS4 Permit expired on June 30, 2018 but was administratively continued. Guidance from the Maine Department of Environmental Protection (Maine DEP) indicated that compliance may be maintained by implementing modified Permit Year 7 activities for “Permit Year 8” (PY8). CCSWCD submitted permit continuance plans for PY8 MCM 1 and MCM 2 tasks on 6/9/2020 via an email to Maine DEP and no written response from Maine DEP was received within 30 days’ time. Per Plan Modification procedures, “if no response is received in writing by the Maine DEP within one month of the amended plan’s submission, the ISWG will implement the amended plan”.

This report includes a summary of all four education & outreach plans required under MCM 1 of the 2013 MEPDES MS4 Permit including the Stormwater Public Awareness Plan, the Targeted BMP Adoption Plan, the Municipal Permit Awareness Plan, and the Enhanced Outreach Plan. This report also includes a summary of the regional public event (Urban Runoff) in fulfillment of MCM 2 of the 2013 MEPDES MS4 Permit. Additional voluntary (not required by the permit) outreach activities are also included.

MCM1: Public Education and Outreach on Stormwater Impacts Stormwater Public Awareness Plan Task Status Details1 Summarize plan Complete Plan goal: As a result of our efforts, at the end of this permit cycle, 50% of homeowners, implementation aged 35-55, in the 30 regulated small MS4 municipalities will understand that water to date does run off their property, not all is absorbed, and it will carry with it pollutants, such as lawn chemicals, pet waste, and oil drops. This polluted water will enter the storm drain system and discharge, untreated, directly to water bodies used for drinking, fishing, and swimming. Conduct online Complete CCSWCD coordinated an online media campaign for the ISWG region through the ad campaign for a placement of ads on Facebook. The Think Blue video PSA “Don’t Fowl Our Waters” ran on minimum of 6 Facebook from August 13, 2020 through October 31, 2020. Ads were targeted to the months identified awareness audience (homeowners, aged 35-55). The PSA was scheduled to run Spring 2021 but changes to Facebook’s policy on ads pertaining to social issues, which started in November 2020, required alternative ads approved by Maine DEP in December 2020 to be run in Spring 2021. The following data were obtained from Facebook’s advertising metrics for the PSA video: Reach2 5,826 Frequency3 3.03 Impressions4 17,658 Post Engagement5 1,975 Video Plays at 50%6 361 Link Clicks7 160 Link Click-Through Rate8 0.91% Additional Facebook ads were used in the ISWG region to highlight individual stormwater pollutants (chlorides and pet waste) and as a substitute for the PSA ad.

Track behavior change Complete CCSWCD staff documented class evaluations and contacted past class participants to determine which YardScaping practices were implemented. Please see the summary of behavior change reported by participants of PY7 classes, as well as which practices the participants of PY8 classes intend to implement below.

Adult Education Behavior Change Tracking During the fall of 2020, emails and phone calls were made to participants of YardScaping workshop classes held in the fall of 2019 and spring of 2020 to determine class participants’ level of implementation of the YardScaping practices. Follow up emails and phone calls are made six months to one year after the class to allow participants a growing season to implement the recommended practices. Our follow up provided an anticipated rate of behavior change for the YardScaping practices that class participants intended to implement. Of the 113 class participants, 55 participants completed a survey upon completion of the class. Two-thirds of the surveyed class participants responded to the fall 2020 follow up emails and phone calls.

Additional Outreach Activities not identified in the Permit or Outreach Plans Maine Water Environment Association (MEWEA) ISWG/CCSWCD continues to serve on MEWEA’s Stormwater Committee, attend meetings, and assist with the Committee’s technical and outreach efforts. ISWG outreach materials are being used as a basis to educate MEWEA’s membership about stormwater.

ISWG Youth Education Although not a permit requirement, ISWG provides funding to deliver clean water education to K-12 students in each municipality. CCSWCD staff provide the education on behalf of ISWG member communities. In addition, the City of Portland also supports additional stormwater education efforts in Portland schools and recreation camps through their Greener Neighborhoods Cleaner Streams program. Portland Water District (PWD) provides clean water lessons in many ISWG communities which enhance ISWG’s efforts. A summary of students reached, contact hours, and topics covered is provided below.

MCM2: Public Involvement and Participation Urban Runoff 2021 marked the tenth year ISWG supported, promoted, and participated in the Urban Runoff 5k, a community event that promotes clean water and raises awareness of water pollution. In addition to raising awareness, funds raised from the Urban Runoff help support in-school youth education programs in Cumberland and parts of York Counties. Due to COVID-19, the Urban Runoff 5k was held virtually from April 1 through April 30, 2021. The race served as the Public Involvement and Participation event for all ISWG communities. Participation by each ISWG municipality is summarized in the table below.

Despite the pandemic, over 150 runners and walkers registered for the race. Many local businesses supported the race through sponsorships, in-kind donations, and employee participation as race participants. Local media outlets advertised the events, including the donation of tv advertisement by Channel 8 WMTW/CW who developed and ran a 15-second ad promoting the event. Social media, paid online advertising, and email were also used to promote the race and included a clean water message. Additional clean water messages were included on the event website, social media, eblasts, and other marketing tools that were sent to all registered participants, sponsors, and partners. Participants submitted photos of their completed Stormwater Hero Bingo cards, sights (including stormwater BMPs) they saw along their route, and their route course designs through Facebook, Instagram, and email.

Plans are underway to host the eleventh annual Urban Runoff 5K in 2022.

Stormwater Permit Awareness

Presenter:

Steven S. Johnson, P.E. Town Engineer

April 22, 2021

What is Stormwater? Precipitation or melted snow that flows over the land...

…plus anything that is carried with it. Common Pollutants

• Soil, sand, and sediment • Fertilizer • Pesticides • Pet waste • Road salt • Litter • …And more

Polluted Runoff Poll Question #1

Permit Awareness • Regulated municipalities must have a permit to direct stormwater runoff to water bodies in their communities while minimizing pollutants. • Municipal Separate Storm Sewer System (MS4) • 5-year permit cycles, first permit issued in 2003 • Additional regulations in each permit cycle • Heading toward year 9 of the current 5-year permit! • Next permit effective July 1, 2022 Regulated Entities are Subject to:

• Full compliance with permit requirements in six steps • Improvement and protection of your priority water bodies • Heightened scrutiny from DEP, EPA, and environmental groups • Higher costs than non-regulated entities

Cost of Compliance vs. Non-Compliance

• More cost-effective to comply with requirements • Noncompliance can result in: • Fines up to $25,000 per day, per violation • More rigorous CWA requirements Interlocal Stormwater Working Group (ISWG) 14 regulated municipalities & 2 nested MS4s in the Greater Portland and Saco areas • Working cooperatively to address stormwater permit requirements • Coordinated by Cumberland County Soil & Water Conservation District • Satisfying permit’s education requirements and parts of public participation

Benefits of Regional Collaboration

• Cost savings: $11,125 member dues (FY ’21) • Meet education requirements without having to hire a dedicated staff person • One consistent message across the region • Advocate with regulators – DEP & EPA • Collaborate with partners – MMA, Environmental Nonprofits, MTA, State Agencies • Provide common framework for collective problem solving, training information exchange Parts of the Permit

Requirement #1 Public Education & Outreach:

Educate the public and municipal staff and officials about polluted runoff and how to reduce pollution. Requirement #2 Public Participation:

Provide the public an opportunity to participate in your town’s stormwater program.

Requirement #3 Illicit Discharge Detection & Elimination:

Identify and eliminate sources of pollution. Carry out long-term maintenance and mapping of all stormwater infrastructure. Requirement #4 Construction Site Runoff Control:

Ensure that construction on both public and private property does not impact water resources.

Requirement #5 Stormwater Management after Construction:

Implement new development and redevelopment stormwater ordinances; encourage developers to use techniques to reduce impact of development on water resources. “LID” and Green Infrastructure Are Different!

Low Impact Development Green Infrastructure • Systems or practices that • Broader, big picture term that mimic natural processes at the includes site level (pre-development • LID hydrology) • Land conservation • Focuses on installing • Other practices to protect stormwater management natural areas at watershed features during development scales or redevelopment

Source: USEPA, https://www.epa.gov/nps/urban-runoff-low-impact-development

Requirement #6 Good Housekeeping & Pollution Prevention:

Prevent pollution from municipal operations and facilities; educate municipal staff about practices to reduce polluted runoff. Impaired Waters Requirements

• Requires discharges to be consistent with Total Maximum Daily Load (TMDL) Waste Load Allocations (WLAs). • DEP may require MS4 to do more if new TMDLs issued.

Accountability

• Must keep comprehensive records documenting compliance for all requirements • Annual reports • Audits • Conducted by EPA and/or DEP • All regulated entities can anticipate being audited at least once per permit cycle Poll Question #2

New with 2022 Permit Remand Rule

Court ruling that National Pollutant Discharge Elimination System (NPDES) rules violated Clean Water Act • Insufficient public participation in permit process • Lack of permitting authority review

Key take-away for Maine MS4s for 2022 permit: • New “Two-step” permitting process, additional requirements after initial submittals • All permit requirements must be “Clear, Specific, and Measurable”, and reduce pollutants to the “Maximum Extent Practicable (MEP) • Expanded requirements for public comment & participation

• Municipalities prepare SWMP & IDDE Plan March • Municipalities submit NOI & SWMP to DEP 2021

• DEP provides any notices of deficiency May 2021

• DEP reviews SWMPs & drafts Permittee-specific DEP Orders May-Dec • Municipalities review Permittee-specific DEP Orders 2021 • DEP holds 30-day public comment on Permittee-specific DEP Orders

• MS4 Permit becomes effective July 2022 • Municipalities implement new requirements 2022 Permit Requirement Increases

MCM 1 (changes may have minor fiscal impact) • Requires education & outreach to: • Public • Municipal, Development/Construction, Commercial, OR Institutions • Two audiences of choice

MCM 2 (changes may have minor fiscal impact) • Must allow public to comment on SWMP • Must make stormwater program accessible for public participation • Annually host/conduct/participate in a public event

2022 Permit Requirement Increases MCM 3 (changes have significant fiscal impact) • Written IDDE Plan • New dry weather outfall flow monitoring requirement • Prepare for wet weather monitoring requirements in 2027

MCM 4 (moderate fiscal impact) • Requires ordinance or other regulatory mechanism • Requires written inspection procedures • Requires an annual inspection if construction is longer than 1 year 2022 Permit Requirement Increases MCM 5 (no major changes) • All sites need to be inspected by “qualified inspector” • Site maintenance must be corrected within 60 days of identification or provide schedule for completion

MCM 6 (moderate changes) • Modify existing SWPPP to comply with new requirements

2022 Permit Requirement Increases Impaired Waters (major changes) • Must implement 3 BMPs per Chapter 502 Urban Impaired Stream • Most impaired waters that have TMDLs are already being addressed • Permittee must consult with DEP regarding any non-TMDL impairments Poll Question #3

Friends of Casco Bay Appeal

RE: Yarmouth Water District BMPs for MS4 Requirements

Dear Kristie:

This letter is a summary of the Yarmouth Water District’s Best Management Practices (BMPs) to address chlorinated water during the District’s unidirectional flushing program. We currently flush the distribution system semiannually and continually perform regular maintenance flushing throughout the year.

We currently use Pollard LPD-250 as a diffuser and dechlorination device during our unidirectional and maintenance flushing. Dechlorination is achieved by using D-Chlor tablets (sodium sulfite), where pre- dechlorination residuals are typically between 0.42 – 0.62 mg/L with an average of 0.52 mg/L.

Where dechlorination of super-chlorinated water is required, we use one of two options. Our first option is to coordinate with the Town of Yarmouth in using the municipal sewer as a point of discharge. If that option is not feasible, we use a tripod utilizing a gravity-fed tank of CAPTOR (Calcium Thiosulfate) that is diffused through the Pollard LPD-250 connection to neutralize the chlorine. These applications are typical where new mains are installed and disinfected with 25– 50 mg/L chlorine residual in the main.

The District also makes an effort to diffuse and divert the water along the pavement, grass areas, and other land applications, to further neutralize any remaining chlorine residual, while being conscious to erosion, before the flow enters the receiving waters.

We periodically conduct field tests to determine the effectiveness of land application and chemical dechlorination of flushing waters to ensure chlorine levels are below 0.05 mg/L reporting limit. Based on our most recent field tests conducted at the discharge of the dechlorination device, the total residual chlorine concentrations have been below the detection limits of our chlorine analyzer. The District will use these methods and continue to periodically test to ensure adequate dechlorination of flushing waters is both effective and economical. The District operators have been trained to contact the Town of Yarmouth if chlorinated water at or above the reporting limit of 0.05 mg/L has been discharged to receiving waters.

The District utilizes GIS mapping and has an MS4 priority hydrant layer for flushing purposes that will signify hydrants that are close to watershed boundaries and streams. This will allow operators to quickly identify hydrants that are critical, ensure proper dechlorination methods are used, and streamline field testing data. Attached you will find a screenshot of the GIS Map that our Operators use in the field. In this map, the hydrants are color-coded according to their flush cycle and MS4 priority hydrants have a red circle around them.

Feel free to contact the District if you have any questions or concerns.

Sincerely,

Eric Gagnon Superintendent
