The Municipal Complex includes a bus maintenance building; a paint shop; a garage for storage of city equipment and other vehicles; vehicle washing areas; salt and aggregate storage; a vehicle impound lot; a public-access natural gas fueling station; a gasoline, diesel, and natural gas bus fueling station; an indoor bus storage building; and administrative offices. Stormwater runoff at the site sheet flows via multiple storm drains to the center of the facility and then leaves the facility via a single outlet towards the south of the property. The Municipal Complex is bounded by Lycoming Creek to the west, which is protected by an approximately 50-foot-tall levee. Permit Appendix A, MCM#6, BMP#2 requires the permittee to "Develop, implement and maintain a written Operations and Maintenance (O&M) program for all operations that could contribute to the discharge of pollutants from the regulated small MS4, as identified under BMP Unique Project Identifier: 3E21WN010A Page 5 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania #1. This program shall address stormwater collection or conveyance systems within the regulated MS4. The written O&M program shall stress pollution prevention and good housekeeping measures, contain site-specific information, and include the following: a. Management practices, policies, procedures, etc. shall be developed and implemented to reduce or prevent the discharge of pollutants to your regulated small MS4s. You should consider eliminating maintenance-area discharges from floor drains and other drains if they have the potential to discharge to storm sewers. b. Maintenance activities, maintenance schedules, and inspection procedures to reduce the potential for pollutants to reach your regulated small MS4s. You also should review your procedures for maintaining your stormwater BMPs. c. Controls for reducing or eliminating the discharge of pollutants from streets, roads, highways, municipal parking lots, maintenance and storage yards, waste transfer stations, fleet or maintenance shops with outdoor storage areas, salt / sand (anti-skid) storage locations and snow disposal areas. Controls for solid chemical products stored and utilized for the principal purpose of deicing roadways for public safety must be consistent with the BMPs for existing salt storage and distribution sites contained in the PAG-03 NPDES Permit for Stormwater Discharges Associated with Industrial Activity. d. Procedures for the proper disposal of waste, including dredge spoil, accumulated sediments, trash, household hazardous waste, used motor oil, street sweepings, and other debris. (1) New permittees shall develop and implement a written O&M program by the end of the first year of permit coverage and review and update the program each year thereafter. (2) All permittees must review and update the written O&M program each year of permit coverage, as necessary." Site Visit Observations: The EPA Inspection Team made the following observations related to the City's pollution prevention and good housekeeping at the Municipal Complex. 1) The City foreman filled out an inspection checklist that was developed after the October 28-30, 2020 EPA offsite compliance audit to document the Municipal Complex site inspection (refer to Appendix A, Exhibits 1 and 2). 2) The EPA Inspection Team observed floor drains in the Public Works building (1550 W 3rd Street). The City foreman stated that the floor drains flow to an oil/water separator, which is cleaned "a few times per year." The EPA Inspection Team observed numerous small oil stains inside the Public Works building, most of which had been covered with oil absorbent. The City foreman also stated that vehicle washing only occurs inside this building. 3) The EPA Inspection Team observed an uncovered scrap metal dumpster outside of the Public Works building with metal overflowing the top of the dumpster (refer to Photographs 1 and 2). The City foreman stated that the dumpster is emptied "every three to four months." This observation was not noted in the City foreman's inspection report. Unique Project Identifier: 3E21WN010A Page 6 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania 4) The EPA Inspection Team observed multiple storm drains at the Municipal Complex. All storm drains contained a significant amount of snow. 5) The EPA Inspection Team observed an uncovered five-gallon bucket with an unknown yellow liquid outside of the "American Building," approximately 30 feet from a storm drain (refer to Photograph 3). The City foreman stated that he did not know what was in the bucket or why it was uncovered outside. The EPA Inspection Team returned to the area approximately 30-45 minutes later and the bucket was still present. This was not noted in the City foreman's inspection report. 6) The EPA Inspection Team observed one covered asphalt bin and two covered salt bins along the western boundary of the Municipal Complex (refer to Photograph 4). The roof and walls appeared to be in good condition and there was minimal debris on the ground in front of the covered structure. 7) The EPA Inspection Team observed an uncovered vehicle impound area behind the asphalt and salt bins (refer to Photograph 5). The impound area was fenced and locked. The City foreman stated that this area belongs to the police, but stated that they did not know if vehicle fluids were emptied before vehicles were stored. 8) The EPA Inspection Team observed a large amount of scrap materials stored uncovered along the northwestern corner of the Municipal Complex property (refer to Photographs 5 through 7). 9) The EPA Inspection Team observed a public access brush pile between the Municipal Complex and the levee along Lycoming Creek (refer to Photograph 7). 10) The EPA Inspection Team observed a public access compressed natural gas fueling station located near the southwest corner of the Municipal Complex (refer to Photographs 8 and 9). 11) The EPA Inspection Team observed three 55-gallon drums of used oil (refer to Photograph 10), two partially filled 330-gallon totes containing used oil (refer to Photograph 11), and one partially filled 330-gallon tote containing diesel exhaust fluid (refer to Photograph 12) stored inside the "American Building" located in the north central portion of the Municipal Complex. All containers were inside of a covered building but lacked secondary containment. The building had no floor drains. A small oil spill was observed on the floor without oil absorbent (refer to Photograph 13); however, oil absorbent was available in this building. When asked, City representatives were unsure about what training is provided to employees working in the garages regarding spill prevention and clean up. The EPA Inspection Team recommended training employees and documenting spill and cleanup activities. 12) The EPA Inspection Team observed a natural gas processing facility in the center of the Municipal Complex (refer to Photograph 14). City representatives stated that natural gas used for buses is pulled directly from the ground; the Municipal Complex does not receive shipments of natural gas via truck. The Municipal Complex also contains underground gasoline and diesel tanks. 13) The EPA Inspection Team observed an indoor paint booth with no floor drains. City representatives stated that the paint booth had not been used in many years. The EPA Inspection Team did not observe any paint spills on the ground. Unique Project Identifier: 3E21WN010A Page 7 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania 14) The EPA Inspection Team observed a covered bus fueling station for gasoline and diesel (refer to Photograph 15). Spills from this area appear they would flow approximately 50 feet southward towards a storm drain in the employee parking lot of the River Valley Transit building. A spill kit was present. 15) The EPA Inspection Team observed the bus maintenance building where preventative maintenance such as oil changes are performed (refer to Photograph 16). The building also contains a bus wash bay (refer to Photograph 17), bulk motor oil storage (refer to Photograph 18), battery storage (refer to Photograph 19), and a large indoor area for overnight bus storage. Floor drains were present throughout the building and City representatives stated all drains flow to an oil/water separator. Photograph 1.

Site Visit Participants Name Title/Affiliation Jon Sander Engineer, City of Williamsport Marcia LeBeau Environmental Supervisor, WSA Wendy Walter Director of Compliance, Safety & Security, WSA Jeff Hakes Field Technician, WSA Taylor Fontaine Inspector, PG Environmental Cassidy Owen Inspector, ERG Rebecca Serfass Inspector, EPA Region 3 Site Description: Outfall LY06 is located directly adjacent to Elm Park and the Williamsport Streets Department and River Valley Transit Municipal Complex. City representatives stated that this is a known NPDES industrial outfall under Permit Number PA0007455 for Lycoming Engines, an airplane part manufacturer. City representatives were unsure if the MS4 also contributed stormwater flow to this outfall. Permit Appendix A, MCM#3, BMP#4 requires the permittee to "conduct dry weather screenings of its MS4 outfalls and observation points to evaluate the presence of illicit discharges. If any illicit discharges are present, the permittee shall identify the source(s) and take appropriate actions to remove or correct any illicit discharges. The permittee shall also respond to reports received from the public or other agencies of suspected or confirmed illicit discharges associated with the storm sewer system, as well as take enforcement action as necessary. The permittee shall immediately report to DEP illicit discharges that would endanger users downstream from the discharge, or would otherwise result in pollution or create a danger of pollution or would damage property, in accordance with Part A III.D.4 of this permit. An observation point must be established by the permittee at a location upstream of any discharge of stormwater into storm sewers owned or operated by an adjoining municipality. (1) For new permittees, all of the identified regulated small MS4 outfalls shall be screened during dry weather at least twice within the 5-year period following issuance of this permit. (2) For existing permittees, each of the identified regulated small MS4 outfalls shall be screened during dry weather at least once by November 30, 2025. For areas where past problems have been reported or known sources of dry weather flows occur on a continual basis, outfalls shall be screened annually during each year of permit coverage. (3) If a discharge is observed from any outfall during dry weather screenings, the discharge shall be inspected for color, odor, floating solids, scum, sheen, and substances that result in Unique Project Identifier: 3E21WN010A Page 18 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania observed deposits in the surface waters. In addition, the discharge cannot contain substances that result in deposits in the receiving water or produce an observable change in the color, odor or turbidity of the receiving water." Site Visit Observations: The EPA Inspection Team made the following observations related to the City's illicit discharge detection and elimination at Outfall LY06: 1) The outfall headwall opens to Lycoming Creek at the bottom of an approximately 50-foottall levee. The EPA Inspection Team did not walk down the levee due to safety concerns, but flow was observed leaving the outfall from the top of the levee (refer to Photograph 20). City representatives stated that there is always a discharge from this outfall, even during dry weather, due to the industrial process water discharge. Permit Number PA0007455 for Lycoming Engines includes several permitted outfalls, one for industrial process water, three for groundwater cleanup discharges, and six stormwater outfalls. At the time of the inspection, it was unclear if any of the Lycoming Engines Outfalls correspond to Outfall LY06 and it was unclear if the observed flow was industrial sourced or from stormwater. A zoomed-in photograph of the outfall showed a short channel with rip rap between the headwall and Lycoming Creek (refer to Photograph 21). 2) City representatives did not complete outfall inspection checklists during the EPA inspection; however, the City provided inspection checklists (dated January 28, 2021) for each of the outfalls visited following the EPA inspection (refer to Appendix A, Exhibit 3). The inspection checklist made note of dry weather flow during the inspection and stated that the flow was from a recovery well from Lycoming Engines (Permit Number PA0007455), but did not disclose how the origin of the flow was determined.

The privately managed basin Unique Project Identifier: 3E21WN010A Page 20 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania was designed with a stormwater storage area, trash rack, concrete riser outlet structure, outlet pipe, and vegetated buffer along the perimeter. According to site representatives, the detention basin eventually discharges into the receiving water, Laurel Run Creek. Permit Appendix A, MCM#5, BMP#1 states that the permittee shall, "Enact, implement and enforce an ordinance or SOP to require post-construction stormwater management from new development and redevelopment projects, including sanctions for non-compliance. (1) Municipal permittees shall enact, implement, and enforce an ordinance to require the implementation of PCSM BMPs, including sanctions for non-compliance. All municipal permittees shall submit a copy of an ordinance that is consistent with DEP's 2022 Model Stormwater Management Ordinance (3800-PM-BCW0100j) as an attachment to an Annual MS4 Status Report by September 30, 2024 (existing permittees) or the fourth (4th) Annual MS4 Status Report following issuance of this permit (new permittees); (2) Permittees that lack the authority to enact ordinances shall develop, implement and enforce an SOP to require the implementation and maintenance of PCSM BMPs and submit the SOP to DEP by September 30, 2024 (existing permittees) or the fourth (4th) Annual MS4 Status Report following issuance of this permit (new permittees); Permit Appendix A, MCM#5, BMP#3 requires the permittee to, "Ensure adequate O&M of all post-construction stormwater management BMPs that have been installed at development or redevelopment projects that disturb greater than or equal to one acre, including projects less than one acre that are part of a larger common plan of development or sale. An inventory of PCSM BMPs shall be developed by new permittees by the end of the first year of Permit coverage and shall be continually updated during the term of coverage under the Permit as development projects are reviewed, approved, and constructed. Existing permittees shall update and maintain its current inventory during the term of coverage under the Permit." Site Visit Observations: The EPA Inspection Team made the following observations related to the City's post construction stormwater management at the Laurel Run Circle infiltration basin BMP: 1) The EPA Inspection Team observed the detention basin contained excess vegetation within the basin and along the perimeter (refer to Photographs 22 and 23). This same issue was referenced during a routine inspection by the City in May 2019, with instructions to correct the referenced deficiency (refer to Appendix A, Exhibit 4). However, at the time of the inspection, City representatives were unsure if follow-up to the deficiency letter was ever completed. 2) The EPA Inspection Team observed the detention basin outlet, concrete riser structure, and trash rack (refer to Photographs 24-26). From what was visible, the structures appeared to be in good condition and no trash was observed. 3) After the inspection, the City provided the EPA Inspection Team with an inspection form completed by Mr. Jon Sander, City Engineer (refer to Appendix A, Exhibit 5). The completed form also made note of the excess vegetation within the basin.

According to the inspection checklist, Outfall WB01 receives flow from Fox Hollow Run as well as permitted entities General Cable (Permit Number PA0009318) and Penn Recycling Inc. (Permit Number PAR604841). 2) The EPA Inspection Team observed Fox Hollow Run flowing through a subsurface channel beneath the Susquehanna Beltway (refer to Photograph 37). Fox Hollow Run subsequently runs through a large levee to Outfall WB01. 3) The EPA Inspection Team observed the ditch between Outfall WB01 and the West Branch Susquehanna River (refer to Photograph 38) from the top of the levee. The surface of the ditch was frozen and covered in snow, but some rip rap was observed in the upstream half of the ditch. 4) The EPA Inspection Team observed the large headwall containing Outfall WB01 (refer to Photograph 39). The headwall contained three pipe flap gates opening to a small notched weir, which subsequently flowed to the ditch to the West Branch Susquehanna River. Flow was observed from the bottom of the central pipe flap gate. City representatives stated that there is always a discharge from this outfall due to the proximity to Fox Hollow Run, but did not state if formal tracing had been performed to confirm this. Additionally, the City's outfall inspection checklist (dated January 28, 2021) for this outfall did not state if formal tracing had been performed (refer to Appendix A, Exhibit 3).

Outfall WB19 is located approximately 1,000 feet to the northeast of Outfall WB18. The outfall consists of a single pipe with a flap gate and a headwall. Permit Appendix A, MCM#3, BMP#4 requires the permittee to "conduct dry weather screenings of its MS4 outfalls and observation points to evaluate the presence of illicit discharges. If any illicit discharges are present, the permittee shall identify the source(s) and take appropriate actions to remove or correct any illicit discharges. The permittee shall also respond to reports received from the public or other agencies of suspected or confirmed illicit discharges associated with the storm sewer system, as well as take enforcement action as necessary. The permittee shall immediately report to DEP illicit discharges that would endanger users downstream from the discharge, or would otherwise result in pollution or create a danger of pollution or would damage property, in accordance with Part A III.D.4 of this permit. An observation point must be established by the permittee at a location upstream of any discharge of stormwater into storm sewers owned or operated by an adjoining municipality. (1) For new permittees, all of the identified regulated small MS4 outfalls shall be screened during dry weather at least twice within the 5-year period following issuance of this permit. (2) For existing permittees, each of the identified regulated small MS4 outfalls shall be screened during dry weather at least once by November 30, 2025. For areas where past problems have been reported or known sources of dry weather flows occur on a continual basis, outfalls shall be screened annually during each year of permit coverage. (3) If a discharge is observed from any outfall during dry weather screenings, the discharge shall be inspected for color, odor, floating solids, scum, sheen, and substances that result in observed deposits in the surface waters. In addition, the discharge cannot contain substances Unique Project Identifier: 3E21WN010A Page 46 of 48 Inspection Date: February 9, 2021 MS4 Audit Report - Site Visit Inspections City of Williamsport, Pennsylvania that result in deposits in the receiving water or produce an observable change in the color, odor or turbidity of the receiving water." Site Visit Observations: The EPA Inspection Team made the following observations related to the City's illicit discharge detection and elimination at Outfall WB19: 1. City representatives did not complete outfall inspection checklists during the EPA inspection; however, the City provided inspection checklists (dated January 28, 2021) for each of the outfalls visited following the EPA Inspection (refer to Appendix A, Exhibit 3). There were no observations or issues of note documented on the inspection form. 2. The EPA Inspection Team observed a headwall adjacent to the West Branch Susquehanna River (refer to Photograph 46). The outfall was partially submerged (refer to Photograph 47), and the surface of the water was frozen, but a small amount of flow was observed in the ditch between the outfall and the West Branch Susquehanna River. City representatives stated that an unnamed creek contributes to this outfall and is piped beneath the levee to the outfall headwall. The EPA Inspection Team observed no maintenance issues associated with the outfall. Levee Outfall headwall Photograph 46. View, facing northwest, of Outfall WB19 at the base of a levee.

Turbotville, Pa. Re: Maintenance of detention pond City of Williamsport, Lycoming County, PA Dear Mr. Yoder, On May 30, 2019 I conducted a routine inspection of the large detention pond which is located on the Western side of the development at Pennsy Heights. Upon speaking with some neighbors and through my own observations, my findings are as follows. All concrete structures are in very good condition and appear to be operational. I did find some excess vegetation throughout as well as light debris which appears to have come from surrounding houses. Please correct the above referenced deficiencies and respond by 30 August, 2019. Please let me know if you have any questions.

August 2, 2016 -Approximately 100 gallons of digested sludge was spilled onto a paved area at the WSA West Plant, of which approximately 20 gallons flowed to the ground. The incident was caused by an equipment malfunction during a pilot study. Please see the attached notification letter to PaDEP on August 5, 2016 for further details. VIII.NON-STORMWATER DISCHARGE ASSESSMENT AND CERTIFICATION Attached IX. SUMMARY OF POLLUTANT SOURCES - SITE ASSESSMENT I. The most likely place for an accidental spill is the unloading docks where raw materials are delivered. The transfer of materials from incoming trucks to storage areas is a potential source of pollution. Although there are no present problems, absorbents, brooms, and shovels are available to quickly contain any spill. 2. A vehicle accident on Interstate 180 could result in a chemical spill. Page 3 of7 July 10, 2019 3. Gasoline used for lawn mowers is a potential source ofpollution. Gasoline storage and use will be addressed in the WSA Safety Training Program as part of the lawn mower safety section. 4. There is no vehicle washing conducted at this facility. 5. There is no outdoor storage of chemicals at this facility. X. BEST MANAGEMENT PRACTICES 1. Good Housekeeping: The WSA West Plant is dedicated to maintaining a clean and orderly work environment. The following housekeeping practices will be implemented so that releases of hazardous substances or oil to stormwater do not occur: a. Maintain up-to-date material inventory. Identify all chemical substances present in the workplace and maintain current SDSs. b. All containers and piping shall be appropriately labeled. c. Cleanup duties are routinely assigned by the Superintendent. d. All work areas are to be kept well organized and neat. e. All employees will be trained about good housekeeping practices. f. The paved areas around the plant will be swept as necessary to prevent debris from entering stonnwater impounding area. g. Obsolete chemicals will be appropriately disposed. 2. Preventative Maintenance: a. Daily inspection of exterior offacility for debris and spilled material or leaks that could enter the stormwater impounding area. b. Weather permitting, monthly inspection of the roof area for debris to ensure that the roof drains are clear. c. A minimal appropriate amount of gasoline will be kept on site. d. 55-gallon drums of oil will be stored and used on containment skids. e. Unloading procedures will be followed to prevent a spill of material. f. Inspect the riprap channels and outfalls after each heavy rainfall event. Immediately make all needed repairs to prevent future damage. Replace any stones which have been dislodged and repair any eroded areas with additional riprap. Record the information on the Facility Stormwater Management log, which has been attached as part of this plan. 3. Spill Prevention and Response: a. The 3,500 gallon above ground fuel oil tank has double wall containment and leak alarms. b. All 55-gallon drums of oil are stored and used on containment skids. c. Good housekeeping practices will be followed. Page 4 of7 July 10, 2019 d. Regular visual inspections to identify areas for potential leaks or spills will be performed e. All spills will be promptly cleaned up, and a supervisor will be notified. f. Appropriate authorities will be notified in the event of a spill. 4. Sediment and Erosion Control: a. Any projects involving earthmoving at this facility shall be in accordance with an appropriate Erosion and Sediment Pollution Control Plan to adequately meet the requirements of Pa Title 25, Chapter 102, Erosion Control. b. Grass shall be maintained in all areas not paved or part of the runoff management system. 5. RunoffManagement: a. The majority of the stormwater runoff from the site is collected by a paved channel which was installed in 2002 to improve the drainage from the site. The northern portion of the channel also serves as an access road. The paved channel is 780 feet long and 8 feet wide. The channel runs from the northwest comer of the site to the east along the base of the U.S. Route 220 embankment. The channel continues along the perimeter of the site and turns to the south along the levee system. There are two rock riprap-lined channels. One is located at the eastern portion and one at the end of the paved channel .where the flow enters a grassy ponding area which was constructed as part of the U.S. Army Corps of Engineers/City of Williamsport Flood Control System. The flow from the channel, along with runoff from the western portion of the site, is normally absorbed by the ground. However, during extended wet weather it may be conveyed through the levee system to the Susquehanna River by a 30-inch flood control pipe and flap gate maintained by the City of Williamsport, located at the southern portion of the site. There is also a valve on the 30-inch outlet pipe on the top of the levee. Plant personnel report that they have never seen a discharge through this outfall. b. The remainder of the stormwater runoff from the site is collected by two stormwater BMP's, a rain garden and vegetated swale, that were installed as part of the West Plant Phase 2 upgrades completed during 2013 -2015. As a requirement of the General NPDES Permitfor Stormwater Discharges Associated with Construction Activities that was required to be submitted by the WSA and approved by the PaDEP in order to complete the Phase 2 upgrades, a Post Construction Stormwater Management (PCSM) Plan was included and approved, which identified these required BMP's and their long term operation and maintenance. The Long Term Operation and Maintenance of the PCSM BMPs for the rain garden and vegetated swale (Section 4 - Permanent Best Management Practices and Section 5-Maintenance) have been included as Appendix I ofthis plan for easy reference. Continued implementation of the Long Term Operation Page 5 of? July 10, 2019 and Maintenance Plan is guaranteed by a property deed covenant and is enforceable by the Lycoming County Conservation District. XI. EMPLOYEE TRAINING 1. Who must be trained: Operators, Assistant Operators, Maintenance Crew 2. When will training occur: a. Employee safety training meetings are held each month which include discussion on the following topics: o Any environmental/health and safety incidents o Upcoming training sessions o Brief reminders on good housekeeping, spill prevention and response procedures, and material handling practices o Announce any changes to the plan o Announce any new management practices b. In-depth pollution prevention training for new employees. c. Refresher courses held annually to address: o Good housekeeping o Spill prevention and response procedures o Material handling and storage 3. Employee Training Program Topics: o Contents and purpose of this plan, including the Long Term O&M Plan of the rain garden and vegetated swale o Review and demonstrate basic clean-up (sweeping) procedures o Clearly indicate proper disposal locations o Location ofroutine clean-up equipment 4. Spill Prevention and Response: o Clearly identify potential spill areas and drainage routes o Familiarize employees with past spill events - why they happened and the environmental impact o Post emergency contacts and telephone numbers 5.

PERMANENT BEST MANAGEMENT PRACTICES The following permanent erosion and sediment control measures have been installed: Rain Garden Vegetated Swale A. Rain Garden I. General Description Rain gardens serve as a method of treating stormwater by pooling water on the surface and allowing filtering and settling of suspended solids and sediment at the surface layer, prior to entering the plant/soil/microbe complex media for infiltration and pollutant removal. Design and planting techniques are used to accomplish water quality improvement and water quantity reduction. The rain garden installed at the West Plant in June 2016 is constructed with an overflow catch basin to direct excessive rainfall runoff to the vegetated swale and the West Plant stormwater channel via a controlled release discharge. The rain garden receives pavement sheet flow runoff from the south and west sides of the headworks building in addition to catch basin discharge. 2. Sizing and Design of the Rain Garden The site's rain garden has been designed in accordance with the PaDEP BMP Manual with the following criteria: Existing soil has an acceptable infiltration capacity. Sub-grades are uncompacted. Ponding depths were designed to be 12 inches and drain within 6 hours. Side slopes will be 3: 1. Emergency spillways will provide positive outflow. The bottom of the rain garden is level, with a planting soil depth and plant selection specified in the Tables 1&2 below. 3. Maintenance and Inspection The rain garden will be routinely inspected and maintained by the plant Superintendent as follows: a. At least two times per year, the area will be inspected for sediment buildup, erosion, vegetative conditions, etc. b. Annually, remove any accumulated leaves and other detritus. c. At the end of the growing season, typically October, cut down perennial plantings. d. Twice per year, evaluate the health of the trees and shrubs. Replace as necessary. e. Annually, inspect the overflow catch basin discharge piping, cleaning or repairing as necessary. f. In addition to the itemized inspection items at the frequencies listed above, a Stormwater Management Inspection Form must be completed quarterly. The form has been attached to this Appendix. B. Vegetated Swale 1. General Description Vegetated swales are broad, shallow, typically trapezoidal channels that receive runoff from adjacent impervious surfaces and are designed to slow it down, promote infiltration, and filter pollutants and sediments in the process of conveying the runoff. The vegetated swale installed at the West Plant in April 2015 conveys the stormwater discharge from the rain garden and sheet flow runoff from paved areas on the southwest side of the existing administration building to the preexisting drainage swale along the south side of the property which discharges to a 30-inch stormwater pipe that passes through the levee to the Susquehanna river. The pipe is equipped with a one-way flap gate to prevent stormwwater on the river side of the levee from entering the site during extremely high river levels. 2. Sizing and Design of the Vegetated Swale The site's vegetated swale has been designed in accordance with the PaDEP BMP Manual with the following criteria: Existing soil has an acceptable infiltration capacity. Sub-grades are uncompacted. Ponding depths were designed to be 12 inches and drain within 6 hours. Side slopes will be 3:1 with a bottom width of 6 feet. The design depth is 24 inches. The swale bottom has a slope of 0.5% and the planting mix to be used can be found in the Tables 1&2 below. 3. Maintenance and Inspection a. Operation and maintenance of the vegetated swale is limited to grass mowing and periodically removing any excessive blown-in debris or leaf build-up. b. In addition to the itemized inspection items at the frequencies listed above, a Stormwater Management' Inspection Form must be completed quarterly. The form has been attached to this Appendix. C.

Shrub and Tree Plantings The following tables consist of the vegetation planted in the rain garden and/or vegetated swale at the West Plant. The contents of the tables should be used as a resource ifi'when vegetation needs replaced, although other appropriate vegetation may be used.

Apply soil amendments as determined by conditions on site and soil nutrient testing after final grade has been established. 2. * Indicator status is defined as follows: OBL Obligate Wetland FACW Facultative Wetland FAC Facultative Occurs almost always (estimated probability 99%) under natural conditions in wetlands. Usually occurs in wetlands (estimated probability 67% - 99%), but occasionally found in nonwetlands. Equally likely to occur in wetlands or nonwetlands (estimated probability 34% - 66%). 3. 3 tons per acre of straw mulch will be applied immediately after the grass seed mixture for permanent BMP seeding. Temporary seeding, where erosion control blankets are not used, shall be stabilized within 4 days of disturbance. 6 tons per acre of agricultural lime and 1,000 lbs per acre of I 0-10-20 fertilizer will be applied prior to seeding/mulching, unless soil testing recommends different ratios. E. Housekeeping/Pollution Prevention The following housekeeping and pollution prevention practices will be implemented so that releases of hazardous substances or oil to stormwater do not occur: Store, as appropriate, only enough products on-site required to complete the project. Store materials in a neat, orderly manner in their original containers (unless they are not re-sealable), and with either the materials original manufacturer's label or replacement label that identify the contents of each container. Follow manufacturer's recommendations for proper use and disposal, and do not mix substances with one another unless recommended by the manufacturer. Use, whenever possible, all of the product before disposing of the container. If surplus product must be disposed of, follow manufacturers' or state/local recommended methods for disposal. Inspect material storage areas routinely to verify proper use and management of materials for, at a minimum, the following: o Leaks, corrosion, and integrity of containers o Accumulated liquids on the ground o Improper labeling and storage practices o Opened or deteriorated containers Provide a secondary containment berm, or other device, for onsite containers with a 55-gallon capacity or larger that are utilized to store ethanol, diesel fuel, gasoline fuel, oil, or other hazardous substances to ensure residual material resulting from leaks/drips do no enter into the stormwater discharge. Conduct routine maintenance such as replacement and repair of leaking fittings, valves, hoses, or other equipment. Remediate/clean-up minor spills which pose no threat to site personnel that may have resulted from leaking containers, equipment leaks, spilled materials, or other site specific operations immediately after discovery. In the unlikely event that a discharge of hazardous substance or oil in an amount equal to or in excess of a reportable quantity does occur, the E&SC Plan will be modified as needed, within 14 calendar days following the event to include measures to prevent a similar type of release from reoccurring and responses to such a release if a similar release occurs. In addition, a description of the date and cause of the release and the clean-up measures taken will be included in the E&SC Plan as well as reported to the proper state and federal agencies. F. Record Retention/Reporting A record of inspections will be maintained by the WSA. These inspection records will include the date(s) and name(s) of personnel making the inspection and results (including any major observations and corrective actions taken or needed). Notification will be made to the Lycoming County Conservation District for any BMP failures or modifications to E&S controls. ,..

Internal Review and Recommendations No comments were received from the public, the operations section, or EPA. The permittee submitted a response to the Department's draft permit / PRP deficiencies along with additional comments in an email dated 11/9/2020. The responses/ comments are as follows: PRP technical deficiency comment responses: 1. Department Deficiency: Please provide additional details regarding the regenerative stormwater conveyances (BMP-224 & BMP-238). In specific, provide a more comprehensive eligibility review analysis for each of these projects. (These reviews should be identical to the stream restoration reviews.) Deficiency Response: WAJMS4s have developed additional support information in reference to BMPs 224 and 228. The documents are provided as Attachment A. Department Response: The Department has determined that the additional information provided satisfies the deficiency and this BMP will be approved with the PRP. 2. Department Deficiency: Regarding the Hidden Valley Basin Retrofit (BMP-239), please provide additional details for this project. In specific, if this structure was constructed under a 102 Permit, please provide documentation that the described capacity issue is not due to a lack of compliance with the PCSMs. (Essentially, this structure should be retrofitted due to a design need and not due to a lack of maintenance.) Deficiency Response: This structure was not constructed under a 102 Permit to the knowledge of Loyalsock Township. The BMP location was investigated as part of the PRP development process and it was determined that the basin bottom soils and outlet structure is not sufficient at adequately delaying stormwater flows from the contributory area. Loyalsock Township has had preliminary discussions with the site owner to make necessary retrofits to increase stormwater control at this location through enhanced soils, vegetation, a longer outlet discharge path, and retrofit/new outlet control structure.

Department Deficiency: Please ensure that your stream restoration projects (see BMP-237 Miller's Run at Short Park) only account for areas where a permanent 35' minimum riparian buffer can be maintained alongside the stream itself. Update Table 6 of your PRP as necessary. Deficiency Response: Loyalsock Township has identified the area adjacent to the existing walking/bike path near the softball fields at Short Park as having adequate space to allow for a 35 foot minimum riparian buffer for the approximate length identified in the stream restoration documentation attachment (Appendix E of PRP). Existing site features (parking lot and path) will be evaluated for relocation as part of the stream restoration design to ensure buffer is maintained. Department Response: The Department has determined that the additional information provided satisfies the deficiency and this BMP will be approved with the PRP. Draft NPDES MS4 Permit comments: 1. WAJMS4s request clarification of their status as either `Existing' or `New' permittees. Status of varies throughout the draft permit (see example in comment 4 below). Many of the MCM requirements vary based on whether existing or new. Department Response: City of Williamsport and Loyalsock Township Joint Client are considered to be an existing permittee currently covered under NPDES permit PAI134808. Once this proposed permit is issued, the previous permit will be terminated. 2. WAJMS4s request clarification to the following Appendix Requirements: a. Page 1, Appendix D (Chesapeake Bay) is specifically listed as required. Are Appendix C (Susquehanna River) or Appendix E (Spring Run) required? b. Pages 21 and 22 - Appendix C, D, and E each mentioned generally, but only Appendix D is required on cover page 1, and only Appendix D requirements are attached. (ie: The cover page is inconsistent with latter pages, including attachments.) Additionally, this is different than what has been included in other permits issued locally (e.g.: South Williamsport). Department Response: The appendices were listed incorrectly and not attached. The applicable appendices are Appendix C, D, and E. These will be added to the permit documents accordingly. 3. Page 6, Unanticipated Non-compliance or Potential Pollution Reporting - WAJMS4 is requesting clarification regarding what defines a "non-compliance event which may endanger health or the environment:" a. Would this include all illicit discharges? Is there guidance regarding types of pollution and /or quantity thresholds? (For example: 2 gallons of hydraulic fluid or 10 gallons per minute of potable water). b. Page 16, BMP#4 contains similar language, please clarify guidelines on reporting. Department Response: Illicit discharges would be determined and reported using Part C.I.3.d.3 of the permit. Refer to 25 Pa. Code 91.33(a) Incidents causing or threatening pollution for the general definition of this requirement. "25 Pa. Code 91.33(a) does not provide a threshold amount of a substance that triggers mandatory notification requirements under this section. However, notification should be provided to DEP about any quantity of a substance that spills, discharges, or otherwise enters waters of the Commonwealth if the release may endanger downstream users, may result in pollution, may create a danger of pollution, or may damage property. When there is some question regarding whether a spill or release requires notification of DEP or not, DEP recommends that a Responsible Party err on the side of notification. Notifying DEP of these incidents requires minimal effort (i.e., a phone call) and can help prevent or minimize hazards to the environment, public health, and public safety. The decision to notify DEP may also affect liability because failure to notify DEP can result in a civil penalty, pursuant to the Department's exercise of its enforcement discretion." This is an excerpt from the Guidance on Notification Requirements for Spills, Discharges, and other Incidents of a Substance Causing or Threatening Pollution to Waters of the Commonwealth Under Pennsylvania's Clean Streams Law (383-4200-003) which can be located on the Department's eLibrary website. 4.

New permittees have until 4 years post issuance. Are WAJMS4s considered existing or new? Other areas of the permit state that WAJMS4s are an existing permittee. WAJMS4s request clarification. Department Response: These dates are entered in at the time of issuance. The dates will be set to four years after issuance (2024) for an existing permittee. The abovementioned changes will be applied to the draft permit.
