INTRODUCTION
On October 28-30, 2020, staff from U.S. Environmental Protection Agency (EPA) Region 3 and EPA's contractor, PG Environmental (hereinafter, EPA Audit Team) conducted an offsite compliance audit of the municipal separate storm sewer system (MS4) program of the City of Williamsport, Pennsylvania (hereinafter, City or Permittee). Representatives of the Williamsport Sanitary Authority (WSA) and Pennsylvania Department of Environmental Protection (DEP) also attended the audit. Discharges from the City's MS4 are regulated by the National Pollutant Discharge Elimination System (NPDES) Individual Permit (IP) for Stormwater Discharges From Small Municipal Separate Storm Sewer Systems (MS4s) (Permit No. PAI134808 A-2; hereinafter, the Permit), effective April 1, 2014 - March 31, 2019 which has been administratively extended. This Permit includes the following co-applicants: City of Williamsport, Pennsylvania College of Technology, Old Lycoming Township, Borough of Montoursville, Hepburn Township, Fairfield Township, Lycoming Township, and Loyalsock Township. The City, along with Loyalsock Township applied for individual Permit coverage on October 1, 2018. At the time of the audit, the new Permit was under a public comment period. A copy of the existing Permit is included as Appendix A.
The purpose of this audit was to obtain information to assist EPA in assessing the City of Williamsport's compliance with the requirements of the Permit, as well as the implementation status of its current MS4 program. The presentation of audit observations in this report does not constitute a formal compliance determination or notice of violation.
The audit focused on the following Permit components:
Overall Program Management Illicit Discharge Detection and Elimination (IDDE) Construction Site Stormwater Runoff Control Post-Construction Stormwater Management (PCSM) in New Development and
Redevelopment Pollution Prevention and Good Housekeeping Pollutant Control Measures and Pollutant Reduction Plans (TMDL Implementation)
The EPA Audit Team obtained its information through a records review and a series of interviews via conference calls with Williamsport and WSA representatives. A copy of the EPA records request with Williamsport's response is included in Appendix B. The following primary representatives were involved in the audit:
City Representatives:
Mr. Jon Sander - Williamsport City Engineer Mr. Scott Dolan - City of Williamsport Administrative Foreman at Streets and Parks
WSA Representatives:
Ms. Marcia Lebeau - WSA Environmental Supervisor Ms. Wendy Walter - WSA Director of Compliance, Safety, and Security Mr. Michael Miller - WSA Executive Director

CITY OF WILLIAMSPORT BACKGROUND
The City encompasses approximately 9 square miles of land in north-central Pennsylvania with the West Branch Susquehanna River serving as the southern boundary. According to the 2010 U.S. Census, the total population of the City is 28,186. The City comprises approximately 25% industrial/commercial land and 75% residential and operates a combined sewer system (CSS) that collects both sanitary sewage and stormwater. The City currently has 40 stormwater outfalls and 162 miles of storm sewer. The City is located within the Chesapeake Bay and Susquehanna River watersheds. Locally, the City's primary receiving waters are the Susquehanna River, Daugherty Run, Fox Hollow Run, Spring Run, Lycoming Creek, Cemetery Run, Grafius Run, and McClures Run.
At the time of the audit, the City had in place a service agreement with WSA to handle administrative aspects of the Permit (e.g., annual report development, tracking of MS4 program goals). The City is responsible for the implementation and execution of the MS4 program and is ultimately responsible for Permit compliance. The City and WSA were in discussions about transferring all responsibilities of the MS4 program and Permit to WSA by establishing a stormwater utility. At the time of the audit, no timeline for this transition had been established. City representatives explained that currently the City's General Fund supports stormwater management projects and operational costs associated with implementing the MS4 program, including fees for MS4 administrative services provided by WSA.
The City has a Public Service Agreement (PSA) with WSA and Memorandums of Understanding (MOUs) with WSA, Loyalsock Township, and the County of Lycoming and Clean Water Institute of Lycoming College, which establish a basis for cooperation between the entities and the City in implementing the Permit requirements.
On December 21, 2017, WSA agreed to administer the MCMs on behalf of the City as part of a PSA (refer to Appendix C, Exhibit 1). The 2020 amended PSA with WSA (dated August 12, 2020) clarifies the roles, responsibilities, and specifically states that while WSA is responsible for the administrative services, they are not ultimately responsible for MS4 Permit compliance. This responsibility falls to the City. In an MOU with the Lycoming County and Clean Water Institute of Lycoming College, these entities agree to provide stormwater outfall survey field work and laboratory testing for all applicants listed in the Permit to include the City.

INFORMATION OBTAINED RELATIVE TO PERMIT REQUIREMENTS
During the audit, the EPA Audit Team obtained documentation and other supporting evidence regarding compliance with the Permit. Referenced documentation used as supporting evidence is provided in Appendix C, Exhibit Log.
The EPA Audit Team provided the City with a written list of requested records on October 6, 2020 (refer to Appendix B), for review prior to the audit. The City made MS4 program-related documents available electronically to the EPA Audit Team on October 15, 2020. Following the audit discussions, the EPA Audit Team did not have any additional documentation requests.
The following sections describe and outline Permit requirements and observations made during the audit.
CHESAPEAKE BAY POLLUTANT REDUCTION PLANS:
Permit Part C.3.a states that the permittee, "Shall within twelve (12) months of the effective date of the Approval of Coverage, develop and submit to DEP for approval a Chesapeake Bay Pollutant Reduction Plan, including a schedule, to implement BMPs to reduce nitrogen, phosphorus, and sediment associated with existing stormwater discharges into regulated small MS4s discharging to receiving waters tributary to the Chesapeake Bay."
As part of the pre-audit records request, City representatives provided the EPA Audit Team with a copy of the City's most recent draft of the Chesapeake Bay Pollutant Reduction Plan (CBPRP) (refer to Appendix C, Exhibit 2). The City's CBPRP was initially submitted to Pennsylvania DEP on October 1, 2018. After developing an amended version in August 2020, the CBPRP's public comment period took place August 3, 2020 through September 2, 2020 and was submitted to Pennsylvania DEP for final approval on September 18, 2020. At the time of the audit, the plan was still pending approval from the State prior to implementation.
MINIMUM CONTROL MEASURE 3: ILLICIT DISCHARGE DETECTION AND ELIMINATION (IDDE)
Permit Appendix A, MCM#3, BMP#4 states, "Following the IDD&E program created pursuant to BMP #1, the permittee shall conduct outfall field screening, identify the source of any illicit discharges, and remove or correct any illicit discharges using procedures developed under BMP #1... For renewal permittees, each of the identified regulated small MS4 outfalls shall be screened at least once during each permit coverage term. 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."
Observation 1:
The City is meeting the Permit-required frequency of screening outfalls "once during each permit coverage term". However, the frequency may not be sufficient to properly detect and eliminate dry weather flows. The City most recently conducted dry weather outfall screenings in 2016.

MS4 Audit Report City Williamsport, Pennsylvania
As part of the pre-audit records request, City representatives provided the EPA Audit Team with a copy of their 2016 Outfall Screening Summary Report as well as their outfall map (dated September 2, 2020) (refer to Appendix C, Exhibits 3 and 4). Staff from the Clean Water Institute of Lycoming College conducted the screening of 40 outfalls, noting the outfall reference number, GPS coordinates, description, and a photograph of each outfall. The outfall map provided by the City includes information gathered during the 2016 outfall screening in addition to identification of the City's eight (8) primary receiving waters.
The EPA Audit Team reviewed in detail the Outfall Screening Summary report and noted that Outfalls WB01, WB10, WB18, WB19, WB21 and LY06 were noted as having dry weather flows. No subsequent investigation was conducted of these dry weather flows. Further, these outfalls were not subsequently screened annually as required by the Permit. Additionally, the EPA Audit Team noted that several outfalls that were determined to have "no flow" were submerged during the 2016 Outfall Screening. City representatives were unable to explain to the EPA Audit Team how conditions of no flow were determined on the submerged outfalls (refer to Appendix C, Exhibits 3).
The City has not been actively screening the outfalls since 2016. It may benefit the City to take a more proactive approach in these outfall screenings.
Permit Appendix A, MCM#3, BMP#5 requires that the Permittee, "Enact a stormwater management ordinance to implement and enforce a stormwater management program (SWMP) that includes prohibition of non-stormwater discharges to the regulated small MS4." Additionally, Permit Appendix A, MCM#3, BMP#1 states the Permittee," shall develop and implement a written program for the detection, elimination, and prevention of illicit discharges into your regulated MS4s."
Observation 2:
The City of Williamsport Stormwater Management Ordinance (hereinafter, Ordinance) was enacted on April 15, 2012. The City provided the EPA Audit Team with a copy of the ordinance prior to the audit (refer to Appendix C, Exhibit 5).
The Ordinance describes unauthorized (illicit) discharges, and allows for penalties of up to $300 per day per violation. The EPA Audit Team noted the City's IDDE plan designates enforcement responsibility of the Ordinance to the Stormwater Management Enforcement Officer but does not outline policies, procedures, or guidance on how or when enforcement should be conducted.
City representatives explained that compliance with the Ordinance to date has been achieved through informal enforcement actions such as verbal warnings. At the time of the audit, City representatives were unaware of any formal

MS4 Audit Report City Williamsport, Pennsylvania
enforcement actions ever undertaken by the City since the Ordinance had been enacted.
MINIMUM CONTROL MEASURE 4: CONSTRUCTION SITE STORMWATER RUNOFF CONTROL
Permit Appendix A, MCM#4, BMP#1 states that the permittee must "Develop your program consisting of all procedures necessary to comply with the requirements of this MCM. Your program shall provide for construction stormwater permitting, construction inspection, and enforcement of installation and maintenance of the necessary Erosion and Sedimentation (E&S) control measures. Your program shall describe clearly how your program will be coordinated with DEP's NPDES Construction Stormwater Permitting program."
At the time of the audit, construction site plans submitted to the City were provided to the City Zoning Officer who would confer with the City Engineer for stormwater measures consistency and compliance. If there were any revisions required, these would be sent to the City Engineer. At the time of the audit, the EPA Audit Team did not find any observations of note related to Minimum Control Measure 4: Construction Site Stormwater Runoff Control.
MINIMUM CONTROL MEASURE 5: POST CONSTRUCTION STORMWATER MANAGEMENT
Permit Appendix A, MCM#5, BMP#1 states that the permittee shall, "Develop a written procedure that describes how the permittee shall address all required components of this MCM. Guidance can be found in the Pennsylvania Stormwater Best Management Practices Manual. This plan shall include the following components:
a. Minimum requirements for use of structural and/or non-structural BMPs in plans for development and redevelopment;
b. Criteria for selecting and standards for sizing stormwater BMPs; c. Implementation of an inspection program to ensure that BMPs are properly installed."
Observation 3:
At the time of the audit, the City had not developed and implemented a documented routine inspection program for ensuring maintenance of Cityowned or private post-construction stormwater BMPs. During audit discussions, City representatives stated that private post-construction stormwater BMPs are primarily inspected on an as-needed reactive basis. City representatives added that in June 2020, the City Engineer conducted inspections at each of the City-owned and private post-construction stormwater BMPs included in the City's current inventory, but this appeared to the Inspection Team to be a one-time occurrence. The June 2020 inspections were not documented or conducted under formal procedures. Furthermore, City representatives stated that the City has never enforced maintenance requirements for private post-construction BMPs.
City representatives stated that the City had 29 publicly owned postconstruction stormwater BMPs that were maintained by the Parks and Streets Departments on an as needed basis, but that maintenance and inspection were not specifically documented for Permit compliance.

Audit Dates: October 28-30, 2020
MS4 Audit Report City Williamsport, Pennsylvania
Permit Appendix A, MCM#5, BMP#6 requires the permittee to, "Ensure adequate Operation and Maintenance (O&M) of all post-construction stormwater management BMPs installed at all qualifying development or redevelopment projects (including those owned or operated by the permittee).
Measurable Goal - 1: Within the first year of coverage under this permit, new permittees shall develop and implement a written inspection program to ensure that stormwater BMPs are properly operated and maintained. The program shall include sanctions and penalties for noncompliance. All permittees shall review and update the inspection program annually and shall continue to implement this BMP."
Observation 4:
The City's Ordinance requires installation and maintenance of postconstruction BMPs. According to Article 1395.02, Operation And Maintenance Agreements of the Ordinance, "The owner is responsible for operation and maintenance of the SWM BMPs. If the owner fails to adhere to the operation and maintenance agreement, the City of Williamsport may perform the services required and charge the owner appropriate fees. Nonpayment of fees may result in a lien against the property.
Each stormwater management plan shall contain provisions which clearly set forth the ownership and maintenance responsibility of all permanent storm water management, and erosion and sediment control facilities. Including:
a. Description of maintenance requirements. b. Establishment of suitable easements for access to all facilities by
public officials, in accordance with this Article. c. Municipalities are exempt from the requirement to sign and record an
operation and maintenance agreement. d. Identification of the responsible party or entity for ownership and
maintenance of both temporary and permanent stormwater management, and erosion and sediment pollution control facilities. In meeting this requirement, the following options are hereby provided for upon approval by the City of Williamsport.
Facilities may be incorporated within individual lots so that the respective lot owners will own and be responsible for maintenance in accordance with recorded deed restriction. A description of the facility or system and the terms of the required maintenance shall be incorporated as part of the deed to the property."
However, the City does not have policies, procedures or guidance on how or when enforcement of the ordinance should be conducted or a plan to ensure private landowners are aware of and following maintenance agreements. At the time of the audit, City representatives were unaware of any formal enforcement actions ever undertaken by the City since the Ordinance had been enacted.

Observation 5:
At the time of the audit, the City did not have language/documentation to ensure that property owners were aware of private BMP maintenance obligations. According to the Ordinance Article 1395.02(d), Operation And Maintenance Agreements, "A description of the facility or system and the terms of the required maintenance shall be incorporated as part of the deed to the property."
During audit discussions, City representatives stated that they followed General Provisions of the Pennsylvania Code (refer to Appendix C, Exhibit 6), Chapter 102.8.(m)(2), post construction stormwater management (PCSM) long-term operation and maintenance requirements (pdf. p. 24) which states, "For any property containing a PCSM BMP, the permittee or co-permittee shall record an instrument with the recorder of deeds which will assure disclosure of the PCSM BMP and the related obligations in the ordinary course of a title search of the subject property. The recorded instrument must identify the PCSM BMP, provide for necessary access related to long-term operation and maintenance for PCSM BMPs and provide notice that the responsibility for long-term operation and maintenance of the PCSM BMP is a covenant that runs with the land that is binding upon and enforceable by subsequent grantees, and provide proof of filing with the notice of termination under 102.7(b)(5) (relating to permit termination)."
During inspection discussions, City representatives stated that Lycoming County implemented Chapter 102 provisions and attached maintenance requirements to property deeds for projects over one acre. In some cases, the City's Ordinance requires PCSM BMPs on projects less than one acre. For example, City PCSM BMP requirements are triggered by the City Ordinance for projects over 5,000 square feet, but not required by County, the City implements maintenance requirements in these cases. However, City representatives stated that in instances where Chapter 102 PCSM BMP requirements were not triggered but City PCSM BMP requirements were triggered, the City had no means to attach maintenance requirements to property deeds. In these instances, maintenance requirements are included in the initial site plans. However, these maintenance requirements were not attached to the property in perpetuity and it was unclear to the EPA Audit Team if the City had the ability to enforce these property specific maintenance requirements attached to initial site plans.
Permit Appendix A, MCM#5, BMP#6, Measurable Goal 2 states that, "An inventory of PCSM BMPs shall be developed by permittees and shall be continually updated during the term of coverage under the permit as development projects are reviewed, approved, and constructed. This inventory shall include all PCSM BMPs installed since March 10, 2003 that discharge directly or indirectly to your regulated small MS4s. The inventory also should include PCSM BMPs discharging to the regulated small MS4 system that may cause or contribute to violation of water quality standard. The inventory shall include:

Audit Dates: October 28-30, 2020
MS4 Audit Report City Williamsport, Pennsylvania
a. All PCSM BMPs that were installed to meet requirements in NPDES Permits for Stormwater Discharges Associated with Construction Activities approved since March 10, 2003.
b. The exact location of the PCSM BMP (e.g., street address); c. Information (e.g., name, address, phone number(s)) for BMP owner and entity
responsible for BMP Operation and Maintenance (O&M), if different from BMP owner; d. The type of BMP and the year it was installed; e. Maintenance required for the BMP type according to the Pennsylvania Stormwater BMP
Manual or other manuals and resources; f. The actual inspection/maintenance activities for each BMP; g. An assessment by the permittee if proper occurred during the year and if not, what
actions the permittee has taken, or shall take, to address compliance with O&M requirements."
Observation 6:
At the time of the audit, the City's inventory of private/City-owned and operated PCSM BMPs was incomplete. As part of the pre-audit records request, the City provided a document titled, "The City of Williamsport Inventory of Development and [Redevelopement] Projects Authorized for Construction that Discharge Stormwater into an MS4 (March 2003 - Present) (refer to Appendix C, Exhibit 7). This inventory was last updated on June 24, 2020 and was initially provided to the City by the County of Lycoming Conservation District. The inventory listed approximately forty-five (45) Cityowned and private projects and associated PCSM BMPs within the City. While the inventory included information on the specific type of PCSM BMP and approximate latitude/longitude, the City did not include all of the information required by the Permit including installation date, required maintenance, and associated inspection/maintenance activities. Additionally, it should be noted that this initial list only included projects that triggered Chapter 102 PCSM BMP requirements and not PCSM BMPs required solely by the City ordinance. WSA and the City have been working to fully complete the list in guidance with Permit requirements. City representatives stated they were unaware of how many of these City-triggered PCSM BMPs may exist and had no means to catalog them.
MINIMUM CONTROL MEASURE 6: POLLUTION PREVENTION AND GOOD HOUSEKEEPING
Due to COVID-19, the audit was conducted remotely; therefore, specific issues related to the onsite conditions of City facilities were not evaluated as a component of the audit. Observations are based on discussions with City representatives and document review.
Permit Appendix A, MCM#6, BMP#2 states that the permittee shall, "Develop, implement and maintain a written operation and maintenance (O&M) program for all municipal operations and facilities that could contribute to the discharge of pollutants from the regulated small MS4s, as identified under BMP #1. This program (or programs) shall address municipally owned stormwater collection or conveyance systems, but could include other areas (as identified under
Enforcement Confidential - Do Not Cite or Quote

Audit Dates: October 28-30, 2020
MS4 Audit Report City Williamsport, Pennsylvania
BMP #1). The O&M program(s) should stress pollution prevention and good housekeeping measures, contain site-specific information, and address the following areas:
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, and salt / sand (anti-skid) storage locations and snow disposal areas.
d. Procedures for the proper disposal of waste removed from your regulated small MS4s and your municipal operations, including dredge spoil, accumulated sediments, trash, household hazardous waste, used motor oil, and other debris."
Observation 7:
At the time of the audit, the City had not developed formal inspection procedures nor were they conducting inspections of municipal operations and facilities as a part of their operation and maintenance program. As part of the pre-audit records request, City representatives provided the EPA Audit Team with a copy of their Pollution Prevention and Good Housekeeping Municipal Operations And Maintenance Plan (refer to Appendix C, Exhibit 8). This Plan (pdf. p. 2) includes language regarding keeping records of inspections and documenting inspections "on an appropriate form". However, at the time of the audit, the City was not regularly conducting inspections of municipal operations and facilities or documenting existing inspection activities. Furthermore, the City had not developed a standard inspection form in order to document these inspection activities. As mentioned previously, due to COVID-19, the EPA Audit Team did not visit any City-owned facilities to verify and evaluate site conditions.
Permit Appendix A, MCM#6, BMP#3 states that the permittee shall, "Develop and implement an employee training program that addresses appropriate topics to further the goal of preventing or reducing the discharge of pollutants from municipal operations to your regulated small MS4s. The program may be developed and implemented using guidance and training materials that are available from federal, state or local agencies, or other organizations. Any municipal employee or contractor shall receive training. This could include public works staff, building / zoning / code enforcement staff, engineering staff (on-site and contracted), administrative staff, elected officials, police and fire responders, volunteers, and contracted personnel. Training topics should include operation, inspection, maintenance and repair activities associated with any of the municipal operations / facilities identified under BMP #1. Training should cover all relevant parts of the permittee's overall stormwater management program that could affect municipal operations, such as illicit discharge detection and elimination, construction sites, and ordinance requirements."

MS4 Audit Report City Williamsport, Pennsylvania
Observation 8:
The City's past pollution prevention and good housekeeping trainings were not provided to all applicable City personnel (i.e., police, fire department, and contractor personnel). As part of the pre-audit records request, City representatives provided the EPA Audit Team with a copy of the attendance log from their 2019 and 2020 training events (refer to Appendix C, Exhibits 9 and 10). The City's Pollution Prevention and Good Housekeeping Municipal Operations And Maintenance Plan, Requirement 3, Develop Employee Training Schedule and Program (pdf. p. 4) states, "The City routinely completes the following trainings as they pertain to activities completed by City employees within the small regulated MS4:
Provide on-site training for new Personnel/Contractor conducted in an informal manner with hands-on training.
Train all personnel involved in activities with pollution potential. Train relevant emergency personnel in proper spill responses. The
local Fire Departments are called in for spills (all fire departments have Hazmat training). The municipality has an Emergency Management Coordinator on staff; he is trained quarterly through Lycoming County's Department of Public Safety."
However, the City did not ensure that representatives from all municipal departments attended these training events as required by the Permit and as stated in the City's training program plan. Additionally, while local fire departments are stated as receiving hazardous materials (HAZMAT) training, it does not appear they are receiving pollution prevention and good housekeeping-specific training. The City should be incorporating representatives from all municipal departments to these training events to educate personnel on preventing or reducing the discharge of pollutants from municipal operations.

PART A
STORMWATER MANAGEMENT PROGRAM (SWMP)
The Stormwater Management Program is contained at Appendix A hereto, which is incorporated by reference herein. The SWMP that you submitted with your application for each of the six (6) MCMs may be either DEP's program or your own alternative program. If you prepared and submitted your own program for any of the MCMs, your program must be at least as protective of water quality as the program in DEP's version of Appendix A. You must implement, enforce and report on such activities related to the approved Stormwater Management Program in Appendix A which is designed to reduce the discharge of pollutants from your regulated small MS4 to the Maximum Extent Practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the federal Clean Water Act, the Pennsylvania Clean Streams Law, and regulations promulgated thereto.
This permit requires enactment and implementation of one of the following: (1) adoption of an MS4 Stormwater Management Ordinance; (2) adoption of an Ordinance from an applicable Act 167 Stormwater Management Plan approved by DEP in 2005 or later; or (3) an ordinance(s) that satisfies all applicable requirements in a completed and signed MS4 Stormwater Management Ordinance Checklist.
1. DEFINITIONS
Applicant: Refers to the owner or operator of a regulated small municipal separate storm sewer system (MS4) seeking to discharge under, and pursuant to, the terms of this permit.
Best Management Practices (BMPs): Schedules of activities, prohibitions of practices, structural controls (e.g., infiltration trenches), design criteria, maintenance procedures, and other management practices to prevent or reduce pollution to the waters of the Commonwealth. BMPs include Erosion and Sedimentation Control Plans, Post Construction Stormwater Management Plans, MS4 TMDL Plans, Stormwater Management Act Plans, and other treatment requirements, operating procedures and practices to control runoff, spillage or leaks, sludge or waste disposal, drainage from raw material storage, and methods to reduce pollution, to recharge groundwater, to enhance stream base flow and to reduce the threat of flooding and stream bank erosion.
Better Site Design (BSD): An approach to residential and commercial development that, when properly conducted, can simultaneously reduce pollutant loads, conserve natural areas, save money, and increase property values. BSD promotes three main goals for new development sites: (1) to reduce the amount of impervious cover, (2) to increase the amount of natural lands set aside for conservation, and (3) to better integrate stormwater treatment systems on-site. Green Infrastructure techniques like green roofs, rain gardens, and vegetated swales can be used in BSD to manage stormwater runoff and increase the amount of local green space. Also, reducing the overall scale of streets, driveways, setbacks, parking spaces, and lot sizes are effective methods of reducing impervious cover. http://cfpub.epa.gov/npdes/greeninfrastructure/information.cfm#glossary
Clean Water Act (CWA): The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 U.S.C. 1251, et. seq.
Control Measure: As used in this permit refers to any BMP in the MS4 Stormwater Management Program, the MS4 TMDL Plan or any other method used to prevent or reduce the discharge of pollutants to waters of the Commonwealth.
Consistent with the TMDL: Implementing measures as soon as practicable to make measurable progress in substantially reducing the applicable pollutant loads specified in the applicable WLA of the TMDL, and ultimately achieving the pollutant reductions required in the WLA through implementation of measures in accordance with an implementation timeline contained in the MS4 TMDL Plan.
Department: The Department of Environmental Protection (DEP)
Designated uses: Those uses specified in 25 Pa. Code 93.4(a) and 93.9a - 93.9z for each waterbody or segment whether or not they are being attained.
Director: The Secretary of the Department of Environmental Protection or any authorized employee thereof.
- 4 -
3800-PM-BPNPSM0200g 2/2012 Authorization to Discharge
Dry Weather: For required outfall inspections, dry weather is a continuous time interval without stormwater producing events that immediately follows an initial 48 hour period with no stormwater producing events. (NOTE: For additional information regarding dry weather, see Chapter 11 of Illicit Discharge Detection and Elimination: A Guidance Manual for Program Development and Technical Assessments [CWP, October 2004]. http://cfpub.epa.gov/NPDES/stormwater/idde.cfm.)
Existing uses: Those uses actually attained in the waterbody on or after November 28, 1975, whether or not they are included in the water quality standards.
Illicit Connection: Any physical connection to a separate stormwater drainage system that conveys illicit discharges into the system and/or is not authorized or permitted by the local authority.
Illicit Discharge: Any discharge (or seepage) to a municipal separate storm sewer that is not composed entirely of stormwater. This does not refer to discharges authorized under an NPDES permit (other than the NPDES permit for discharges from the regulated small MS4); certain allowable non-stormwater discharges described in the EPA regulations, NPDES MS4 permit or the MS4 permittee's ordinance; and discharges resulting from fire fighting activities. Examples of illicit discharges include dumping of motor vehicle fluids, household hazardous wastes, grass clippings, leaf litter, animal wastes, or unauthorized discharges of sewage, industrial waste, restaurant wastes, or any other non-stormwater waste into a separate stormwater drainage system. Illicit discharges can be accidental or intentional.
Load Allocation (LA): The portion of a surface water's loading capacity that is assigned or allocated to existing and future nonpoint sources and natural quality (25 Pa Code 96.1).
Low Impact Development (LID): A set of site design approaches and small-scale stormwater management practices that promote the use of natural systems for infiltration, evapotranspiration, and reuse of rainwater. LID can be applied to new development, urban retrofits, and revitalization projects. LID utilizes design techniques that infiltrate, filter, evaporate, and store runoff close to its source. Rather than rely on costly large-scale conveyance and treatment systems, LID addresses stormwater through a variety of small, cost-effective landscape features located on-site. http://cfpub.epa.gov/npdes/greeninfrastructure/information.cfm#glossary
Maximum Extent Practicable (MEP): A technology-based discharge standard established in the CWA at 402(p)(3)(B)(iii) that requires NPDES MS4 permittees to optimize reductions in stormwater pollutants on a location-by-location basis by minimizing pollutant loads in stormwater discharges and maximizing technically achievable and cost-effective water quality improvements. MEP as used in this program also includes the requirement under the Pennsylvania Clean Streams Law to prevent pollution from changes in stormwater rate, volume, and temperature associated with alteration of the land. The MEP standard requires the development, implementation, and enforcement of measures including BMPs, control techniques, system design, engineering methods, and other provisions that DEP determines to be appropriate for the control of such pollutants. MEP is an iterative, dynamic, flexible standard that the permittee shall evaluate and update continuously, as necessary, to better tailor or expand the program based on its effectiveness in reducing pollutant discharge load.
Measurable Goals: Best Management Practice design objectives or goals that quantify the progress of program implementation and the performance of the chosen BMPs. They are objective markers or milestones that can be used to track the progress and effectiveness of BMPs in reducing pollutants to the MEP.
Municipal Separate Storm Sewer: A conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade channels, or storm drains), which is all of the following:
(1) owned or operated by a state, city, town, borough, township, county, district, association or other public body (created under state law) having jurisdiction over disposal of sewage, industrial wastes, stormwater or other wastes,
(2) designed or used for collecting or conveying stormwater, (3) not a combined sewer, and (4) not part of a Publicly Owned Treatment Works as defined at 40 CFR 122.2.
Municipal Separate Storm Sewer System (MS4): All separate storm sewers that are defined as "large" or "medium" or "small" municipal separate storm sewer systems pursuant to 40 CFR 122.26(b)(18), or designated as regulated under 40 CFR 122.26(a)(1)(v).

The following are the requirements for MCM #3 that are included in the Federal Regulations:
Develop, implement, and enforce a program to detect and eliminate illicit discharges into the MS4 (40 CFR Part 122.34(b)(3)(i)).
Develop, if not already completed, a storm sewer system map, showing the location of all outfalls and the names and locations of all surface waters of the Commonwealth that receive discharges from those outfalls (40 CFR Part 122.34(b)(3)(ii)(A)).
To the extent allowable under State or local law, effectively prohibit, through ordinance, or other regulatory mechanism, non-stormwater discharges into your storm sewer system and implement appropriate enforcement procedures and actions (40 CFR Part 122.34(b)(3)(ii)(B)).
Develop and implement a plan to detect and address non-stormwater discharges, including illegal dumping, to your system (40 CFR Part 122.34(b)(3)(ii)(C)).
Inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper disposal of waste (40 CFR Part 122.34(b)(3)(ii)(D)).
The following requirements, Best Management Practices (BMPs) and Measurable Goals are to be implemented and achieved:
BMP #1: You shall develop and implement a written program for the detection, elimination, and prevention of illicit discharges into your regulated MS4s. Your program shall include dry weather field screening of outfalls for nonstormwater flows and sampling of dry weather discharges for selected chemical and biological parameters. Test results shall be used as indicators of possible discharge sources. The program shall include the following:
a. Procedures for identifying priority areas. These are areas with a higher likelihood of illicit discharges, illicit connections, or illegal dumping. Priority areas may include areas with older infrastructure, a concentration of high-risk activities, or past history of water pollution problems.
b. Procedures for screening outfalls in priority areas during varying seasonal and meteorological conditions. c. Procedures for identifying the source of an illicit discharge when a contaminated flow is detected at a regulated
small MS4 outfall. d. Procedures for eliminating an illicit discharge. e. Procedures for assessing the potential for illicit discharges caused by the interaction of sewage disposal
systems (e.g., on-lot septic systems, sanitary piping) with storm-drain systems. f. Mechanisms for gaining access to private property to inspect outfalls (e.g., land easements, consent
agreements, search warrants). g. Procedures for program documentation, evaluation and assessment.
Measurable Goal: For new permittees, the IDD&E program shall be developed during the first year of coverage under this permit and shall be implemented and evaluated each year thereafter. For renewal permittees, the existing IDD&E program shall continue to be implemented and evaluated annually. Records shall be kept of all outfall inspections, flows observed, results of field screening and testing, and other follow-up investigation and corrective action work performed under this program.
Recommendation: For information on development and implementation of an IDD&E program, refer to: Illicit Discharge Detection and Elimination: A Guidance Manual for Program Development and Technical Assessments (CWP, October 2004). http://cfpub.epa.gov/NPDES/stormwater/idde.cfm
BMP #2: Develop and maintain a map of your regulated small MS4. The map must also show the location of all outfalls and the locations and names of all surface waters of the Commonwealth (e.g., creek, stream, pond, lake, basin, swale, channel) that receive discharges from those outfalls.
Measurable Goals: For new permittees, develop the map(s) of your regulated small municipal separate storm sewer systems (MS4) and the information on all outfalls from your regulated small MS4 by the end of the fourth (4th) year of
- 4 -
3800-PM-BPNPSM0200h 2/2012 Appendix A
permit coverage. For renewal permittees, the existing map(s) of your regulated small MS4 shall be updated and maintained as necessary during each year of coverage under the permit.
BMP #3: In conjunction with the map(s) created under BMP #2 (either on the same map or on a different map), new permittees shall show, and renewal permittees shall update, the entire storm sewer collection system, including roads, inlets, piping, swales, catch basins, channels, basins, and any other features of the permittee's storm sewer system, including municipal boundaries and/or watershed boundaries.
Measurable Goal: For new permittees, develop the map(s) by the end of the fourth (4th) year of coverage under the permit and update and maintain the map(s) as necessary each year of permit coverage thereafter. For renewal permittees, update and maintain the map(s) as necessary during each year of permit coverage.
BMP #4: Following the IDD&E program created pursuant to BMP #1, the permittee shall conduct outfall field screening, identify the source of any illicit discharges, and remove or correct any illicit discharges using procedures developed under BMP #1.
Measurable Goals: For new permittees, all of the identified regulated small MS4 outfalls shall be screened during Dry Weather on at least two (2) different occasions during the permit coverage term. In each permit coverage year, at least forty percent (40%) of the total number of outfalls should be screened.
For renewal permittees, each of the identified regulated small MS4 outfalls shall be screened at least once during each permit coverage term. 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.
For each outfall, if the screening reveals dry weather flow, the discharge from the outfall and the area around the outfall shall be inspected visually for color, turbidity, sheen, floating or submerged solids; for adverse affects on plants or animals in proximity to the outfall; and for odor. If the outfall produces any odor, or if the visual inspection shows any indication that the discharge may contain pollutants, then samples of the discharge shall be collected for field and / or lab testing of selected chemical and biological parameters as part of a process to determine if the dry weather flow is illicit. Common parameters include: pH; conductivity; E. Coli bacteria; fecal coliform bacteria; metals; suspended solids; dissolved solids; oils; ammonia; surfactants; chlorine; and fluoride.
You shall implement the IDD&E plan that you developed to address any non-storm water discharges. If an outfall does not have any dry weather flow, then sampling and testing are not needed.
For all permittees, outfall inspections need to be prioritized according to the perceived chance of illicit discharges within the outfall's contributing drainage area. Observations of each outfall shall be recorded each time an outfall is screened, regardless of the presence of dry weather flow. Proper quality assurance and quality control procedures shall be followed when collecting, transporting or analyzing water samples. All outfall inspection information shall be recorded on the Outfall Reconnaissance Inventory/Sample Collection field sheet (attached below) excerpted from the Illicit Discharge Detection and Elimination: A Guidance Manual for Program Development and Technical Assessments (CWP, October 2004). Adequate written documentation shall be maintained to justify a determination that an outfall flow is not illicit. If an outfall flow is illicit, the actions taken to identify and eliminate the illicit flow also shall be documented.
The results of outfall inspections and actions taken to remove or correct illicit discharges shall be summarized in periodic reports.
Recommendation: All permittees should consider conducting some outfall screenings during varying seasonal and meteorological conditions since it is possible for illicit discharges/connections to occur during different times of the year and during or just after rain events. Seasonal outfall screenings conducted during periods of both low and high groundwater conditions can be beneficial in identifying illicit discharges that can occur during these times.
BMP #5: Enact a stormwater management ordinance to implement and enforce a stormwater management program (SWMP) that includes prohibition of non-stormwater discharges to the regulated small MS4.
- 5 -
3800-PM-BPNPSM0200h 2/2012 Appendix A
Measurable Goal - 1: Within the first year of coverage under the permit, new permittees shall enact and implement an ordinance from an Act 167 Plan approved by the Department in 2005 or later; one (1) of the MS4 Stormwater Management Ordinances; or an ordinance that satisfies all applicable requirements in a completed and signed MS4 Stormwater Management Ordinance Checklist. Renewal permittees must continue to maintain, update, implement, and enforce a Stormwater Management Ordinance that satisfies all applicable requirements. Measurable Goal - 2: New permittees shall submit a letter signed by a municipal official, municipal engineer, or the municipal solicitor as an attachment to their first year report certifying the enactment of an ordinance that meets all applicable requirements of this permit. Renewal permittees shall update their existing ordinance, if necessary, and submit documentation of completion to the DEP. BMP #6: Provide educational outreach to public employees, business owners and employees, property owners, the general public and elected officials (i.e., target audiences) about the program to detect and eliminate illicit discharges. Educational outreach should include:
a. Distribution of brochures and guidance for target audiences including schools; b. Programs to encourage and facilitate public reporting of illicit discharges; c. Organizing volunteers to locate and visually inspect outfalls and to stencil storm drains; and d. Implement and encourage recycling programs for common wastes such as motor oil, antifreeze and pesticides. Measurable Goals: During each year of permit coverage, appropriate educational information concerning illicit discharges shall be distributed to the target audiences using methods outlined under MCM #1. If not already established, set up and promote a stormwater pollution reporting mechanism (e.g., a complaint line with message recording) by the end of the first year of permit coverage for the public to use to notify you of illicit discharges, illegal dumping or outfall pollution. Respond to all complaints in a timely and appropriate manner. Document all responses, include the action taken, the time required to take the action, whether the complaint was resolved successfully.

INTRODUCTION
The City of Williamsport and Loyalsock Township (Applicants) discharge stormwater to surface waters located within the Chesapeake Bay Watershed and are therefore regulated by the National Pollutant Discharge Elimination System Individual Permit to Discharge Stormwater from Small Municipal Separate Sewer Systems. The Applicants submitted a Municipal Separate Storm Sewer System (MS4) individual permit application and a Joint Pollutant Reduction Plan (PRP) to the Pennsylvania Department of Environmental Protection (PADEP) on October 1, 2018, and the Applicants have determined that the PRP should be amended so that it is an implementable plan with confidence that the proposed best management practices (BMPs) meet PADEP's credit eligibility guidelines. This Joint Chesapeake Bay Pollutant Reduction Plan (CBPRP) was developed in accordance with both individual permit requirements, and it documents how the Applicants intend to achieve the pollutant reduction requirements listed in the PADEP Municipal MS4 Requirements Table1 and the NPDES Stormwater Discharges From Small Municipal Separate Storm Sewer Systems Pollutant Reduction Plan (PRP) Instructions2.

SECTION D: DETERMINE EXISTING LOADING FOR POLLUTANTS OF CONCERN
D.1 Planning Area
The spatial extents of the 2018 Joint PRP planning area was utilized and pollutant loads were modeled utilizing Model My Watershed. Model My Watershed is the present day iteration of the Mapshed and GWLF-E watershed modeling tools. These tools have been developed to support total maximum daily load (TMDL) and MS4-related watershed analyses and have been identified by PADEP guidance for developing PRPs as an acceptable approach for calculating baseline loads and load reductions.
Consideration was given to areas outside of the urbanized area when delineating the planning area. Namely, storm sewersheds contributing to the impaired streams were reviewed for pollutant reduction BMP opportunities. Consequently, the extents of the planning area were adjusted as necessary to include areas draining to potentially beneficial BMP locations and the baseline pollutant loading was increased to accommodate for the additional planning area.
D.2 Parsed Area Calculation
In order to calculate the actual pollutant loads applicable to the City's and Township's MS4s, the PRP instructions allow areas that do not drain to the MS4 and areas that are already covered by their own MS4 or other NPDES permit to be removed from the planning area through the parsing process4.
Therefore, the following areas were removed from the CBPRP and PRP planning areas:
PennDOT roadway and land area - The estimated pollutant load from stormwater runoff generated by PennDOT roadways located within the Planning Area was parsed from the existing pollutant base load, as PennDOT maintains their own MS4 permit to account for stormwater runoff generated from their facilities.
Non-municipal stormwater NPDES permit area - land area associated with non-municipal stormwater NPDES permit coverage that exists within the urbanized area of a municipality.
Land area that does not enter the MS4 - as defined by PADEP, if an accurate storm sewershed map is developed, these lands may be parsed or excluded as part of that process. Potential examples include homeowner's associations and schools which do not contain municipal roads or their municipal infrastructures. Also, areas that directly discharge to surface water without entering the MS4 may be parsed.
Combined sewer system area - it has also been determined during preliminary discussions between the City of Williamsport, Loyalsock Township, and PADEP, along with the MS4 FAQ, that all stormwater draining to Combined Sewer Outfalls (CSOs) can be parsed from the planning area because it is regulated under a different NPDES program.

A summary of parsed area removed from the Applicant's planning area is shown in Table 2. Parsed areas are shown on the CBPRP Planning Area Map (Appendix B). Supporting information for the pollutant load calculations using Model My Watershed output associated with each parsed area included in Appendix D.

-3,674 -1,201 4,626
D.3 Existing Pollutant Load Calculation
The existing pollutant loadings were calculated using the Model My Watershed online tool and BMP Spreadsheet. In accordance with this method, 2011 National Land Cover Database is the default land use file used by Model My Watershed. The existing pollutant loading was determined for the Planning Area as well as for each watersheds' PRP planning areas, as this is the native output from Model My Watershed.
The pollutants of concern identified in Section C are total suspended solids (TSS), total nitrogen (TN), and total phosphorus (TP); however, it is presumed that within the overall Bay watershed, the TP and TN goals will be achieved when the permit-required sediment reduction is achieved. Therefore, only the TSS pollutant loading was calculated in Table 3. Detailed pollutant load calculations are provided in Appendix D.

D.4 Existing Pollutant Loading Adjustment for Previously Implemented BMPs
Loyalsock Township and the City of Williamsport adjusted Planning Area contains various previously installed BMPs, which continue to function as designed. The municipally-owned BMPs

are maintained by public works staff, and are inspected regularly. Privately owned BMPs located within the Planning Area are to be maintained in accordance with Operation and Maintenance agreements recorded with the land development plan or local municipal stormwater ordinances.
Land use information from aerial flight data and PADEP's standard BMP Effectiveness Values5 were used to estimate the pollutant load reduction associated with BMPs. Additional information on existing BMPs is provided in Appendix E. The locations of existing BMPs are shown on the CBPRP Planning Area Map in Appendix B.
Since the 2018 CBPRP was finalized, an inventory of additional installed stormwater BMPs was completed. The inventory was cross referenced with available BMP characteristics to determine the TSS removal efficiencies for existing BMPs and baseload reductions were calculated for the additional BMPs.

SECTION E: BMPS TO ACHIEVE THE REQUIRED POLLUTANT LOADING REDUCTIONS
E.1 Required Pollutant Reduction Calculation
The Applicants discharge stormwater to surface waters located within the Chesapeake Bay Watershed and must address PA DEP Appendix D requirements (nutrients and sediment in stormwater discharges to waters in the Chesapeake Bay watershed). The pollutants of concern for Appendix D are TSS, TP, and TN, with required loading reductions of 10-percent, 5-percent, and 3-percent, respectively. However, as previously described, it is presumed that within the overall Bay watershed, the TP and TN goals will be achieved when a 10-percent reduction in sediment is achieved6. Therefore, only the required 10-percent TSS reduction is calculated herein as a requirement for planning area load reductions (Table 5). The pollutant load reduction

requirements listed below consider adjustments to baseline loading from the parsed areas and existing BMPs discussed in Section D.
The total CBPRP planning area required sediment load reduction is 229,991 lbs/yr. The municipalities have agreed to share responsibility for reducing the sediment loading as follows: The City of Williamsport will have a reduction requirement of 80,497 lbs/yr or 35% of the total required loading and the remaining 149,494 lbs/yr or 65% of the required reduction will be the responsibility of Loyalsock Township. The memorandum of understanding documenting the agreement and roles and responsibilities of the municipalities is included in Appendix G.

E.2 Proposed BMPs
This section outlines the BMP implementation strategy developed to achieve the required pollutant load reduction goals stated in Section E.1. The proposed BMPs were determined through discussions with municipal staff, in-field site assessments, and public outreach meetings.
A summary of the type and scale of BMP projects included in the pollutant reduction strategy is listed in Table 6. The pollutant loading reductions for each proposed BMP were calculated in terms of pounds per year using a combination of the Expert Panel Report7 and PADEP's standard BMP Effectiveness Values8. Calculations for the anticipated pollutant load reductions for each BMP in Table 6 is provided is provided in Appendix F.

E.3 Secondary Projects and Meeting the MS4 Goal
The inherent complexity of implementing numerous, large-scale projects in a five-year timeframe with limited annual cash flow and limited land control, necessitates a significant number of alternate projects be identified and included in this plan in order to provide flexibility during implementation. As projects are completed and reported on in MS4 Annual Reports, plan implementation progress will be quantified. The plan goal will be accomplished once the implemented projects meet the joint planning area load reduction goal. For those planned projects that are not completed during the individual permit term because the goal has been met, the MS4s reserve the possibility of implementing the projects in the future should there be a new regulatory water quality improvement goal.
Should any projects proposed be deemed to be unachievable during the five-year plan implementation, additional projects have been identified as secondary sites. The Applicants recognize their ability to review and revise the sediment reduction strategy put forth in this Joint Plan and may elect to do so in at some point in the future in accordance with PADEP regulations. Projects on the primary BMP project lists may shift to the secondary project list (identified in Tables 7 and 8) based upon actual feasibility upon initiation of the project and, conversely, alternate projects may shift to the primary project list. Calculations for the anticipated pollutant load reductions for each BMP in Table 7 is provided is provided in Appendix F.

SECTION F: FUNDING MECHANISMS
Financing of the design and construction of the BMPs proposed herein will be funded through a variety of sources including the Township's and City's general funds, available grants, and public donation of materials and manpower.
The City of Williamsport has been in discussions to transfer the ownership and operation of all stormwater infrastructure to the Williamsport Sanitary Authority. Further, the Williamsport Sanitary Authority has investigated a stormwater utility fee to assist with funding the maintenance of the stormwater system infrastructure. At this time there is no further detail on this funding mechanism, but it is anticipated a stormwater utility fee may be a tool to assist with the funding of municipal stormwater infrastructure operations, maintenance, and capital program in the future.

The Applicants are mutually responsible for meeting their joint sediment reduction requirements as stated in the memorandum of understanding between the City and Township. Once implemented, the BMPs outlined in this plan will be operated and maintained by the City of Williamsport and Loyalsock Township staff and inspected regularly by the Applicants MS4 Program
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
10
Coordinators to ensure that they continue to provide the expected pollutant reductions. Table 8 provides a summary of BMP type, priority, and responsible party for maintenance based on project location. The Operation and Maintenance (O&M) activities will be reported in the Annual MS4 Status Reports submitted in accordance with the joint Individual Permit. Projects located within private property will require an easement, if not already existing.
The O&M activities and schedule for each BMP will be developed during the design phase. A general summary of the O&M activities involved with each BMP type and the frequency at which O&M activities will occur are as follows:
Bioretention, Infiltration Basins, and Retrofits (Bioswales and Basin Retrofits)
Operation and maintenance requirements for the bioretention, infiltration basin, and basin retrofit projects include:
Ensure disturbed areas are kept free of foot and/or vehicular traffic until full stabilization has occurred. Properly designed and installed Bioretention areas require some regular maintenance.
While vegetation is being established, pruning and weeding may be required. Detritus may also need to be removed every year. Perennial plantings may be cut down
at the end of the growing season. Mulch should be re-spread when erosion is evident and be replenished as needed. Once
every 2 to 3 years the entire area may require mulch replacement. Bioretention areas should be inspected at least two times per year for sediment buildup,
erosion, vegetative conditions, etc. During periods of extended drought, Bioretention areas may require watering. Trees and shrubs should be inspected twice per year to evaluate health.
The contractor shall be responsible for the operation and maintenance of the bioretention/infiltration/basin retrofit practices until all features of the project have been successfully constructed to the specifications and design standards set forth by the Applicants' Engineer(s). The Contractor should provide a one-year 80% care and replacement warranty for all planting beginning after installation and inspection of all plants.
Once construction of the project(s) is complete, the Applicant(s) shall be responsible for long term implementation of all Operation and Maintenance procedures to ensure the basin remains operationally functional and physically consistent with the original design.
Stream Restoration/Stabilization
Operation and maintenance requirements for a stream restoration project includes: Ensure disturbed areas are kept free of foot and/or vehicular traffic until full stabilization has occurred. Properly designed and installed stream features require some monitoring and regular maintenance. Stream Restoration areas should be inspected at least four times per year for sediment buildup, erosion, vegetative conditions, etc. Trees and shrubs should be inspected twice per year to evaluate health.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan

Once construction of the project(s) is complete, the Applicant(s) shall be responsible for long term implementation of all Operation and Maintenance procedures to ensure the system remains operationally functional and physically consistent with the original design.
Wetlands and Wet Ponds
Operation and maintenance requirements for a wetland or wet pond project includes:
Wetlads/wet ponds should have a maintenance plan and privately-owned facilities should have an easement, deed restriction, or other legal measure to prevent neglect or removal.
During the first growing season or until established, vegetation should be inspected every two to three weeks.
Wetlands/wet ponds should be inspected at least four times per year and after major storms (greater than two inches in 24 hours) or rapid ice breakup. Inspections should access the vegetation, erosion, flow channelization, bank stability, inlet outlet conditions, embankment, and sediment/debris accumulation.
If applicable, the pond drain should also be inspected and tested four times per year. Problems should be corrected as soon as possible.
Wetlands/wet ponds and buffer vegetation may need support (watering, weeding, mulching, replanting, etc.) during the first three years.
Undesirable species should be carefully removed and desirable replacements planted if necessary.
Vegetation should be maintained at least an 85 percent cover of the emergent vegetation zone and buffer area.
Annual harvesting of vegetation may increase the nutrient removal of wetlands; if performed it should generally be done in the summer so that there is adequate regrowth before winter.
Care should be taken to minimize disturbance, especially of bottom sediments, during harvesting. The potential disturbance from harvesting may outweigh its benefits unless the area receives a particularly high nutrient load or discharges to a nutrient sensitive waterbody.
Sediment should be removed from forebay before it occupies 50 percent of the volume, typically every five to 10 years.
If applicable, the contractor shall be responsible for the operation and maintenance of the wetland/wet pond until all features of the project have been successfully constructed to the specifications and design standards set forth by the Applicants' Engineer. The Contractor should provide a one-year 80% care and replacement warranty for all planting beginning after installation and inspection of all plants.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
13
Once construction of the project(s) is complete, the municipality shall be responsible for long term implementation of all Operation and Maintenance procedures to ensure the wet pond remains operationally functional and physically consistent with the original design.
Dry Extended Detention Basin
Operation and maintenance requirements for the dry extended detention basin project includes:
All basin structures expected to receive and/or trap debris and sediment should be inspected for clogging excessive debris and sediment accumulation at least four times per year, as well as after every storm greater than 1 inch.
Structures include basin bottoms, trash racks, outlets structures, riprap or gabion structures and inlets.
Sediment removal should be conducted when the basin is completely dry. Sediment should be disposed of properly and once sediment is removed, disturbed areas need to be immediately stabilized and revegetated.
Mowing and/or trimming of vegetation should be performed as necessary to sustain the system but all detritus should be removed from the basin.
Vegetated areas should be inspected annually for erosion. Vegetated areas should be inspected annually for unwanted growth of exotic/invasive
species. Vegetative cover should be maintained at a minimum of 95 percent. If vegetative cover
has been reduced by 10 percent, vegetation should be reestablished.
If applicable, the contractor shall be responsible for the operation and maintenance of the dry extended retention basin until all features of the project have been successfully constructed to the specifications and design standards set forth by the Applicants' Engineer. The Contractor should provide a one-year 80% care and replacement warranty for all planting beginning after installation and inspection of all plants.
Once construction of the project(s) is complete, the municipality shall be responsible for long term implementation of all Operation and Maintenance procedures to ensure the dry extended detention basin remains operationally functional and physically consistent with the original design.
Roadside Infiltration Trenches/Berms
Operation and maintenance requirements for the roadside infiltration trench project includes:
Catch Basins and Inlets should be inspected and cleaned at least two times per year. The vegetation along the surface of the infiltration trench should be maintained in good
condition and any bare spots revegetated as soon as possible. Vehicles should not be parked or driven on a vegetated infiltration trench, and care should
be taken to avoid excessive compaction by mowers.

condition and any bare spots revegetated as soon as possible. Vehicles should not be parked or driven on a vegetated Subsurface Infiltration Basin, and
care should be taken to avoid excessive compaction by mowers. If access is needed, use of permeable, turf reinforcement should be considered.
If applicable, the contractor shall be responsible for the operation and maintenance of the subsurface infiltration basin until all features of the project have been successfully constructed to the specifications and design standards set forth by the Applicant(s) Engineer. The Contractor should provide a one-year 80% care and replacement warranty for all planting beginning after installation and inspection of all plants.
Once construction of the project(s) is complete, the municipality shall be responsible for long term implementation of all Operation and Maintenance procedures to ensure the subsurface infiltration basin remains operationally functional and physically consistent with the original design.
Street Sweeping
The Applicants have implemented street sweeping programs to help reduce the amount of road debris entering the storm water basins that can lead to sediment and foreign debris being discharged to rivers and streams.
The following is a protocol that the Applicants could utilize to sweep streets and record the pertinent information for street sweeping in order to report to the Department of Environmental Protection:
Streets will be swept up to 26-times a year in the planning area. The operator records the mileage and street name of the streets swept on a Street Sweeping Tracking and Reporting Form.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
15
Mileage is recorded by entering the starting mileage of the sweeper and the ending mileage of the sweeper to give the most accurate total mileage that was swept on any given street.
The debris extracted from the streets would be transported to a public works facility. The debris would be deposited on a protected location and the water is allowed to drain
out of the debris. The amount of debris is recorded by the operator using visual markers and logged onto his
reporting form in cubic yards. Street sweepings are reclaimed or disposed of at a permitted facility.
Inlet/Catch Basin/Pipe Cleaning
The Applicants will seek to implement an inlet/catch basin and pipe cleaning program. Presently the Applicants clean inlets/catch basins and stormwater pipes as needed. As part of the CBPRP, the applicants will seek to clean these stormwater structures on a rotating basis and address areas of high debris loads more frequently. The following is a protocol that the Applicants can use to clean storm water inlets/catch basins/pipes and record the pertinent information for structure cleaning in order to report to the Department of Environmental Protection:
The operator records the pertinent information, including the actual amount of debris in pounds that is being removed from each basin, on a Storm Water Catch Basin and Inlet Inspection Form.
The debris would be extracted from the basins by vactor truck and transported to a public works facility.
The debris is measured by the operator and logged onto a reporting form in net pounds by determining the debris weight using an appropriate method similar to that provided in Expert Panel Report9.

Urban BMP Load Reduction Calculation Table
INSTRUCTIONS: Each row in the table below can represent either different areas of land use/cover within a single planning area (e.g., municipality), or different BMP drainage areas within a given planning area. If an individual planning area has multiple "developed land" types, each type can be represented in separate rows, with each row having the same "Project Name". If it is assumed that the planning area is being reated by one BMP system, then the "Treatment Depth" should be the same for each row. Similarly, a given planning area can have multiple "BMP drainage areas" (i.e., areas treated by different BMP systems). If a BMP drainage area has multiple "developed land" types, separate "land use areas" can be represented on separate rows, with each row having the same "Project Name". Also, the treatment depth should be the same for any row associated with the same Project Name. If runoff from a land use/cover type with NO impervious cover (e.g., Cropland) is treated by a BMP system (either existing or proposed), use the Manual Override (column M) to type in the treatment depth (in/imp. ac). Examples of various options for characterizing different types of project areas are provided in the "Example" spreadsheet that is also available for downloading from the Model My Watershed site.

Lycoming Creek-West Branch Susquehanna River Existing BMP Pollutant Load Reductions
Urban BMP Load Reduction Calculation Table
INSTRUCTIONS: Each row in the table below can represent either different areas of land use/cover within a single planning area (e.g., municipality), or different BMP drainage areas within a given planning area. If an individual planning area has multiple "developed land" types, each type can be represented in separate rows, with each row having the same "Project Name". If it is assumed that the planning area is being reated by one BMP system, then the "Treatment Depth" should be the same for each row. Similarly, a given planning area can have multiple "BMP drainage areas" (i.e., areas treated by different BMP systems). If a BMP drainage area has multiple "developed land" types, separate "land use areas" can be represented on separate rows, with each row having the same "Project Name". Also, the treatment depth should be the same for any row associated with the same Project Name. If runoff from a land use/cover type with NO impervious cover (e.g., Cropland) is treated by a BMP system (either existing or proposed), use the Manual Override (column M) to type in the treatment depth (in/imp. ac). Examples of various options for characterizing different types of project areas are provided in the "Example" spreadsheet that is also available for downloading from the Model My Watershed site.

APPENDIX F: Proposed BMP Documentation
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
Primary Locations
BMP-204 Sand Hill Road Infiltration Berm - The Township is proposing to construct an infiltration berm along the western side of Sand Hill Road. Drainage from the adjacent neighborhood and upland forested area drain onto Sand Hill Road and across onto the other side. The infiltration berm is proposed to retain and infiltrate this runoff.
This BMP will help to reduce volume and rate entering the downstream watershed, allow eroded material upland to be deposited on the berm, and to slowly release runoff stored along the berm to the downstream watershed reducing erosion and sediment deposition.
BMP-205 Robbins Road Infiltration Basin Retrofit - Stormwater runoff from the roadway, residential development, and pervious surfaces up gradient of the existing basin along Warrensville Road between Robbins Road and Sand Hill Road drains directly into this basin via overland flow and direct piping.
The existing basin will be retrofitted to increase capacity, promote infiltration, and improve water quality vegetation. The existing basin will be regraded to improve capacity. Hydrological and Hydraulic computations will be used to resize and redesign the basin outlet structure. Approximately 29 acres of drainage from the local development and forested area will drain to this basin via overland flow and proposed piping system. A new outlet structure will be designed to increase the amount of stored water within the pond to promote infiltration and nutrient uptake from the water quality plantings. The outlet structure will be designed to slowly release runoff from higher storm events into the downstream stormsewer system. This will help to reduce erosion and help to improve capacity in the system by reducing the rate of runoff from the basin and its associated upstream drainage into the piping network.
BMP-246 Mountain Crescent Subsurface Infiltration - A subsurface infiltration BMP is proposed to be placed within the cartway of Mountain Crescent Road. The proposed subsurface infiltration BMP will receive 2 acres of drainage from the local residential neighborhood and a portion of the upland forested area. This BMP will receive drainage through direct piping and overland flow into the stormsewer system. The subsurface BMP will be designed to create a localized groundwater recharge area. This BMP will contain a stone bed which will be open graded clean stone. An overflow device will be designed to convey large storm events such that the runoff rate directed to the downstream stormsewer system is reduced as feasibly possibe.
BMP-201 Becht School Redevelopment Subsurface Infiltration - The proposed subsurface infiltration BMP will receive 2.56 acres of drainage from the local residential neighborhood and Becht School lot. The subsurface BMP will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed which will be open graded clean stone containing a minimum void space of 40%. An overflow device will be designed to convey large storm events such that the runoff rate is reduce as feasibly possible to reduce any accelerated erosion associated with typical overflow devices.
This infiltration BMP is selected to be used due to the limited room available. The existing school has been redeveloped and has created an opportunity for BMP implementation. Existing and proposed stormwater infrastructure will be routed to the proposed BMP within the central open space area.
BMP-214 Ruby Tuesday's/Harley Davidson Basin Retrofit - Stormwater runoff from the parking lots of Ruby's Tuesday and Harley Davidson drains directly into this basin via overland flow and direct piping.
The existing basin will be retrofitted to increase capacity, promote infiltration, and improve water quality vegetation. The existing basin regraded to improve capacity. Hydrological and Hydraulic computations will be used to resize and redesign the basin outlet structure.
A new outlet structure will be designed to increase the amount of stored water within the pond to promote infiltration and nutrient uptake from the water quality plantings. The outlet structure will be designed to slowly
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
release runoff from higher storm events into the downstream stormsewer system. This will help to reduce erosion and help to improve capacity in the system by reducing the rate of runoff from the basin and its associated upstream drainage into the piping network.
BMP-241 Reed Street Stormwater Treatment Wetland - The proposed stormwater treatment will be placed at an existing forested depression. This location was identified due to an existing stream, Bull Run, flowing through this area and the surrounding neighborhood stormwater collection system discharges stormwater into the stream at this location. The Township owned property will be converted into wetlands that will be engineered to retain and treat up to 70 acres of runoff. The existing stormwater outfall pipe will be shortened and runoff will be redirected from directly discharging to Bull Run to discharging into and through the forested area. The constructed wetland will consist of surface regrading to help promote ponding, native water quality vegetation to promote nutrient uptake, and dewatering mechanism for use during extreme flooding events. The constructed wetlands will be hydrogeologically supplied by the drainage area and from groundwater interception of the adjacent Bull Run stream system.
BMP-240 Pennvale-Randall Circle Permeable Pavement and/or Infiltration Basin - Pennvale/Randall Circle is a townhouse development managed by the Lycoming County Housing Authority. The area contains several small parking areas for its residents throughout the development. These parking areas could be targeted to contain new permeable pavement parking aisles.
If a permeable pavement system is utilized, the travel lane through the parking regions will remain as bituminous pavement, with the parking aisles to be converted to permeable pavement. Inlets will be proposed and routed to the infiltration beds beneath the pavement. These small sections of permeable pavement located throughout the development will receive approximately 3 acres of drainage in total consisting of mostly roadway drainage. The pavement will be designed to store water, create a localized region of groundwater recharge, and help reduce peak rates from the impervious roadway. Maintenance of the pervious pavement will consist of street sweeping every 6-months with proper notification to all residents.
The townhouse development also contains several open space areas that runoff drains to from within the neighborhood. These open spaces could be redesigned to contain either surface or subsurface infiltration system. The decision on which BMP will be used will be determined after survey of the region has been completed and piping system mapped.
A surface infiltration system would consist of an infiltration basin. The open space area would be lowered, a forebay will be constructed, and an outlet structure designed. This outlet structure will be designed to store water during low flow situations and reduce peak rate during large storm events. As the open space area is currently used for recreation activities for the residents, the infiltration basin will be seeded with a turf mix and continued to be mowed and maintained. This basin will be strictly for sediment reduction and will provide little water quality benefit.
A subsurface infiltration system would be designed to create a localized groundwater recharge region. This BMP will contain a stone bed which will be open graded clean stone. An overflow device will be designed to convey large storm events.
BMP-224 Loyalsock Community Center Stormwater Management Features
Parking Infiltration Basin - The Loyalsock Community Center parking area will be redesigned to direct runoff to a single infiltration basin or a series of smaller basins. This will be achieved through redirecting the existing parking lot drainage by using inlets and piping to a graded depression (infiltration basin).
The proposed infiltration basin(s) will provide a localized area of groundwater recharge and help to reduce both volume and peak flow discharge Millers Run. The basin will be constructed with an engineered soil
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
media to help promote infiltration and water storage within the soil media. Water quality vegetation will be planted within the basin to promote nutrient uptake and reduce pollution to the groundwater and downstream discharge point.
Greenway Trail - The Loyalsock Community Center Trail will be improved with a series of swales along the trail that will help to direct runoff to an infiltration basin.
The proposed infiltration basin(s) will provide a localized area of groundwater recharge and help to reduce both volume and peak flow discharge to Millers Run. The basin will be constructed with an engineered soil media to help promote infiltration and water storage within the soil media. Water quality vegetation will be planted within the basin to promote nutrient uptake and reduce pollution to the groundwater and downstream discharge point.
Regenerative Stormwater Conveyance - The proposed project will retrofit an existing eroding drainage path into a regenerative stormwater conveyance system. The existing swale will be excavated to include new engineered media and regraded to include various steps, pools, check dams, and other in channel features to help reduce the conveyance velocity and promote infiltration. The conveyance system will be seeded with a wet mix and water quality shrubbery planted along the length of the system. The proposed conveyance system will reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading, and promote nutrient reduction.
BMP-237 Millers Run at Short Park Stream Restoration - The project consists of the restoration of 300 to 450 feet stream segment of Millers Run located within Short Park.
This portion of Millers Run has been targeted for restoration due the extent of bank erosion and loss of bank armoring seen along the Short Park trail. This restoration would consist of construction a more natural stream channel through the use of instream structures such as cross vanes and j-hooks. The project will aim to reestablish the floodplain, remove legacy sediment, and establish a riparian buffer to aid in stabilizing the stream bed and banks and reintroducing a more natural riparian buffer area on the east side of the stream. Constructed features will aid in slowing stream velocity and sediment transport. Incorporating native vegetation through an approximate 70 foot buffer (at least 35 feet on each side of the stream and trail) will help reduce sediment load from runoff entering the stream and provide aquatic habitat, while reducing thermal impacts to the stream.
BMP-250/251 Cameo - Short Park Stormwater Management Facilities - A rain garden and subsurface infiltration facility with be designed within Short Park to control stormwater runoff from the parking lot and open space area. The existing park and parking lot area is located within the Millers Run floodplain. Currently, runoff from this site drains directly into Millers Run via overland flow. The implementation of stormwater controls will help to reduce the volume and runoff directly entering the stream and help to reduce thermal impacts associated with the impervious cover.
A rain garden and subsurface infiltration system will be designed to create a groundwater recharge area. This BMP will contain a stone bed which will be open graded clean stone.
BMP-209 Northway - Church of Saint Ann Infiltration Basin - The runoff from this site directly drains to Millers Run via overland flow. This project is targeted to control the runoff and peak flow rates from the Saint Ann's parking lot and adjacent street runoff where conveyance to the proposed practice is feasible. The basin will be designed with inlets and pipes to direct the stormwater runoff to a new infiltration basin.
The proposed infiltration basin will provide a localized area of groundwater recharge and help to reduce both volume and peak flow discharge to its downstream drainage area. The basin will be constructed with an engineered soil media to help promote infiltration and water storage within the soil media. Water quality vegetation will be planted within the basin to promote nutrient uptake and reduce pollution to the
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
groundwater and downstream discharge point. An engineered outlet structure will be designed to increase stormwater retention from smaller storm events to promote sediment reduction and water storage for further nutrient uptake and slowly release larger storm events.
BMP-239 Hidden Valley Basin Retrofit - An existing basin approximately 1 acre in size is located west of the intersection of Hidden Valley Drive and Fairview Road. This existing basin receives approximately 66.7 acres of drainage from the surrounding development and roadway system. This basin has become impacted from sediment deposition and lack of maintenance, limiting the available capacity within the basin and reducing the ability for vegetation to establish.
The existing basin will be retrofitted to increase capacity, promote infiltration, and provide vegetation to improve discharged water quality. A sediment forebay will be graded into the basin to establish a localized region of sediment deposition. This will allow for easy maintenance by Township staff.
A new outlet structure will be designed to increase the amount of stored water within the pond to promote infiltration and nutrient uptake from the water quality plantings. The outlet structure will be designed to slowly release runoff from higher storm events into the tributary stream to Millers Run. This will help to reduce erosion and help to improve capacity in the system by reducing the rate of runoff from the basin and its associated upstream drainage into the piping network.
BMP-238 Cameo Estates to Northway Regenerative Stormwater Conveyance - The Township is proposing to construct a series of conveyance structures in the drainage channel from Cameo Estates down to Northway Road. The system will convey stormwater runoff from the development to the storm sewer located in Short Park.
A regenerative stormwater conveyance project would consist of grading in a channel that will include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity and promote infiltration. The conveyance system will be seeded with a wet mix and water quality shrubbery planted along the length of the system. The proposed conveyance system will further reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading and promote nutrient uptake.
BMP-223 Faxon Bowling Lanes Subsuface Infiltration - Faxon bowling lane is a completely impervious 1.81 acre lot. All stormwater from this site is directed towards inlets and drains into the local roadway system. The lack of stormwater management, and the minimal land available makes this an ideal candidate for a subsurface infiltration BMP.
A subsurface infiltration system will be excavated under the existing parking lot. The existing inlets will connect to the facility. The infiltration system will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed which will be open graded clean stone. Perforated stormwater pipes placed will be placed throughout the bed bottom to increase detention time and promote infiltration.
BMPs-202/203/220/221 Windfield Drive Roadside Subsurface Infiltration - In the northern part of the planning area along Windfield Drive, four locations have been identified for subsurface infiltration BMP implementation. These roadside infiltration systems will receive drainage from the local roadways, neighborhood development, and adjacent open space. This will be achieved by grading in roadside swales and connecting the existing storm sewer system into the facility.
A subsurface infiltration system will be excavated within the existing right of way of Windfield Drive. The existing inlets will connect to the facility. The infiltration system will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed and perforated storm sewer pipes placed throughout the bed bottom to increase detention time and promote infiltration.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
BMPs-216/219/230 Northwood Drive Subsurface Infiltration and Infiltration Basin Retrofits - Along Northwood Drive, a proposed series of subsurface infiltration basins and infiltration basin retrofits will be constructed along one side of the road and from an existing smaller basin. The existing roadway is located within a flat grade break on a hill. Drainage from the adjacent neighborhood and forested area drain onto the road and travel across the road to the other side where it then continues to drain down the hill. The Township is proposing to design a subsurface infiltration feature to capture and control this runoff volume.
The infiltration basin retrofits will involve over excavating the existing basins and adding engineered media to help promote infiltration. The basins will be designed to store runoff volume and infiltrate it into the ground. These series of practices will help to reduce volume and rate entering Grafius Run and to slowly release runoff stored to the downslope channel, thereby reducing erosion and sediment deposition downstream.
BMP-234 Ravine Road Infiltration Berms/Swales - A segment along Ravine Road contains a road split where there are small sections of landscaped areas in between each through lane. The City is proposing to turn these landscaped areas into drainage swales and then construct and infiltration berm along the downslope of the road. The site will be located in the City but will only take credit pollutant loads reduced from MS4 drainage area.
The infiltration berm will be located on the north side of the road. The berm will be over excavated and an engineered media will be placed to help promote infiltration into the ground. Various drain pipes will be placed throughout the berm to slowly bypass the berm in cases of extreme storm events.
The swales located along the center of the road will be designed to reduced runoff velocity, allow for some infiltration, and target specified discharge regions along the infiltration berm. The swale will become an important deign consideration in control the rate of runoff discharged onto the berm.
This BMP will help to reduce volume and rate entering the downstream watershed, allow eroded material upland to be deposited on the berm, and to slowly release runoff stored along the berm to the downstream watershed reducing erosion and sediment deposition.
BMP-232 Reach Road Infiltration Berms/Swales - The area along Reach Road is fairly flat and existing stormwater runoff from the roadway drains into the adjacent grassed areas before entering stormwater inlets that collect and discharge to Fox Hollow Run. This project is aimed at grading in swales along the side of the road and grading up the sides to promote infiltration and provide additional storage before discharging to the storm sewer system occurs.
The infiltration berms would be located on both sides of the road. The berms will be over excavated and an engineered media will be placed to help promote infiltration and reduce runoff volume and discharge rate.
BMP-L1 Loyalsock Township Street Sweeping - The use of mechanical, regenerative air, or vacuum filter sweepers will be used to conduct street sweeping along the roads of Loyalsock Township. The exact amount of time each road will be swept is dependent on pollutant loading to said road. The Township will target a street sweeping frequency of up to 26 times per year in the non-parsed Planning Area. A street sweeping program will be developed to prepare for parking restrictions and resident notification on when and which streets will be swept. A street sweeping route through the Township will be kept and the total curb mile swept will be tracked for each route.
BMP-L2 Loyalsock Township Inlet/Pipe Cleaning - Loyalsock Township will develop a maintenance program to directly remove sediment from inlets and pipe located throughout the Township. All material removed from these inlets will be properly disposed of to avoid migration back into the watershed. The Township will develop a method for tracking the mass or volume of sediment removed to be used for final computations of sediment and nutrient removal.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
BMP-W1 Williamsport Street Sweeping - The use of mechanical, regenerative air, or vacuum filter sweepers will be used to conduct street sweeping along the roads of Williamsport. The exact amount of time each road will be swept is dependent on pollutant loading to said road. The City will target a street sweeping frequency of up to 26 times per year for targeted roads in the non-parsed Planning Area. A street sweeping program will be developed to prepare for parking restrictions and resident notification on when and which streets will be swept. A street sweeping route through the City will be kept and the total curb mile swept will be tracked for each route.
BMP-W2 Williamsport Inlet/Pipe Cleaning - The City of Williamsport will develop a maintenance program to directly remove sediment from inlets and pipe located throughout the Township. All material removed from these inlets will be properly disposed of to avoid migration back into the watershed. The City will develop a method for tracking the mass or volume of sediment removed to be used for final computations of sediment and nutrient removal.
Secondary Locations
BMP-244 Warrensville Road Wetland/Riparian Buffer - On the eastern side of Warrensville Road lies a frequently flooded parcel near Loyalsock Creek. This region is a low lying area adjacent to the Loyalsock Creek and receives stormwater drainage from local residential and forested areas to the west.
The project itself would consist of riparian buffer plantings along the low lying region and creation of hydrologically connected wetlands. The riparian buffer would provide both water quality benefits and reduce thermal impacts to the Loyalsock Creek. This area most likely contains wetlands due to the low lying area being directly connected to the Creek. If utilized as a project, the Township is proposing to improve and extend the assumed existing wetlands.
The extent of the proposed wetlands would be regraded for maximum retention of water. The area will be seeded and planted with species tolerant to constant inundation with extensive root systems for soil stability. Wetlands will be monitored for establishment, vegetative help, and erosive behavior during flooding conditions.
BMP-245 Mill Creek Bend Regenerative Stormwater Conveyance - This project would be located directly upstream from BMP-244. Stormwater from the adjacent development drains down the hill through an existing drainage ditch and into the existing floodplain of Loyalsock Creek. This project would reconstruct the existing eroding drainage path into a regenerative stormwater conveyance practice.
A regenerative stormwater conveyance project would consist of regrading the channel to include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity and promote infiltration. The conveyance system will be seeded with a wet mix and water quality shrubbery planted along the length of the system. If implemented, the proposed conveyance system will further reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading, promote nutrient reduction, and reduce thermal impacts to the Loyalsock Creek.
BMP-243 Sycamore Road/Haas Lane Stream Restoration or Regenerative Stormwater Conveyance - The Township has identified a length of stream in Bulls Run watershed for stream restoration or to convert the drainage path into a bioswale along. The approximate 400 feet segment is located directly south of Haas Lane and north of Lincoln Drive. The project type will be dependent on design factors assessed in the field during future project scoping.
If selected, restoration would consist of construction of instream features such as cross vanes or j-hook vanes. The floodplain would be reestablished as feasibly possible, legacy sediment will be removed, and a riparian buffer planted to aid in stabilizing the stream bed and banks and reintroducing a more natural stream channel system. Constructed features will aid in slowing stream velocity and sediment transport.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
Incorporating native vegetation through the buffer will help reduce sediment load from runoff entering the stream and provide aquatic habitat, while reducing thermal impacts to the stream.
A regenerative stormwater conveyance project would consist of regrading the channel to include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity and promote infiltration. The conveyance system would be seeded with a wet mix and water quality shrubbery planted along the length of the system.
BMP-207 Hoss's Parking Lot Subsurface Infiltration - Hoss's Restaurant located off of E. 3rd Street, is an almost entirely impervious lot besides a small front portion of the lot. Stormwater from this lot drains into inlets throughout the parking lot and connects to the drainage system on E. 3rd Street.
A subsurface infiltration system would be excavated under the existing parking lot. The existing inlets will connect to the facility. The infiltration system will be designed to create a localized groundwater recharge region. Perforated stormsewer pipes placed would be placed throughout the bed bottom to increase detention time and promote infiltration.
BMP-208 Giant Parking Lot Subsurface Infiltration - Directly north of BMP-207 is the Giant Food Store. The entire shopping center is impervious. Stormwater from this site drains into inlets located throughout the parking area. The stormsewer system from this parking lot connects directly to the drainage system discharging to Bull Run.
An option for retrofit stormwater management would be a subsurface infiltration system excavated under the existing Giant parking lot. The existing inlets will connect to the facility. The infiltration system will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed and perforated stormsewer pipes to increase detention time and promote infiltration. An overflow device will be designed to convey large storm events.
BMP-241 Bull Run - Reed to Edercrest Stream Restoration - The Township has identified a length of Bull Run that could be eligible for stream restoration along a 400 foot segment from Reed Street to Edercrest Road.
A restoration would consist of construction of instream features such as cross vanes or j-hook vanes. The floodplain will be reestablished, legacy sediment will be removed, and a riparian buffer planted to aid in stabilizing the stream bed and banks and reintroducing a more natural stream channel system. Constructed features will aid in slowing stream velocity and sediment transport. Incorporating native vegetation through the buffer will help reduce sediment load from runoff entering the stream and provide aquatic habitat, while reducing thermal impacts to the stream.
BMP-242 Country Club at Lincoln Drive Wetland, Pond, or Regenerative Stormwater Conveyance - The Williamsport Country Club contains a driving range located to the east of Country Club Drive. Located within the driving range is an unnamed tributary to Bull Run. The type of project is dependent on agreements between the Township and the Country Club if this project is sought after.
Option 1: A regenerative stormwater conveyance project would consist of regarding the channel to include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity and promote infiltration. The conveyance system will be seeded with a wet mix and water quality shrubbery planted along the length of the system. The proposed conveyance system would reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading, promote nutrient reduction, and reduce thermal impacts to the Bull Run. This option would be ideal for this project as heavy bank erosion and undercutting can be seen throughout the reach segment. Additional floodplain storage could be added by grading in depressions around the stream segment. These additional storage areas will provide places for sediment deposition during high flow events, and help to reduce flooding in the downstream reach segment.
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
Option 2: Constructed wetlands could be created by excavating the floodplain regions surround the stream segment. This constructed wetland system will be hydrologically supplied through runoff to this region. The constructed wetland would consist of regrading existing land surface to promote ponding, native water quality vegetation to promote nutrient uptake, and dewatering mechanism for use during extreme flooding events.
BMP-211 Wilmont Drive Basin Retrofit - In between Wilmont Drive and the Susquehanna Beltway is an approximate 1.5 acre stormwater detention basin. The basin currently stores runoff from the lots located on Wilmont Drive, and discharges the water across the Susquehanna Beltway.
The existing basin could be retrofitted to accept additional runoff, promote infiltration, and improve water quality vegetation. A sediment forebay will be graded into the basin to establish a localized region of sediment deposition. An option is to construct a berm around the existing outlet endwall to store water within the basin to promote infiltration. The basin retrofit would assist in further reducing erosion by reducing the rate of runoff from the basin and its associated upstream drainage into Bull Run.
BMP-228 Faxon Circle Subsurface Infiltration - Located at the center of Faxon Circle is a landscaped area. The Township is proposing to construct a subsurface infiltration facility within this landscaped area. The facility could receive approximately 3.54 acres of drainage from the local residential lots though the redirection of the existing storm sewer system.
The existing inlets along Faxon Circle will drain into the subsurface infiltration system. The infiltration system will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed and perforated stormsewer pipes to increase detention time and promote infiltration. An overflow device would be designed to convey large storm events such that the runoff rate is reduce as feasibly possible to mitigate the volume and rate of runoff entering the downstream stormsewer system.
BMP-222 Divine Providence Campus Subsurface Infiltration - The Divine Providence Hospital Campus is located along Grampian Boulevard and consists of several healthcare facilities and adjacent parking lots. The lot is mostly impervious with small portions of landscaped areas placed throughout the area. The parcel straddles the City/Township border and a proposed stormwater management system could involve installing a single or series of subsurface infiltration facilities within the parking lot. The facility will receive approximate 2.29 acres of drainage from the parking lot.
The parking lot inlets would be directed to drain into the subsurface infiltration system. The infiltration system will be designed to create a localized groundwater recharge region. This BMP will contain a stone bed which will be open graded clean stone and perforated pipes placed to increase detention time and promote infiltration. An overflow device will be designed to convey large storm events such that the runoff rate is reduced to mitigate the volume and rate of runoff entering the downstream stormsewer system.
BMPs-235/236 Grafius Run Infiltration/Detention Basins - Grafius Run is a watershed that is divided between the City and Township. The watershed runoff collects in Loyalsock Township and travels southward into the City of Williamsport and then enters a subsurface stream conveyance system. Where the stream enters at two locations in the City are areas of frequent flooding. The City has considered improvements to trash racks at these locations and additional runoff or streamflow control measures. At least two potential locations for either an infiltration or detention basin BMP have been identified along the stream before it enters the subsurface stream system. These basins would likely receive drainage from both City and Township areas from the local developments, roadway systems, and act as a flood control BMP during high flow conditions of Grafius Run.
If pursued, the proposed basins could provide a potential region of groundwater recharge and help to reduce both volume and peak flow discharge to the stream. An engineered outlet structure will be designed
City of Williamsport & Loyalsock Township Chesapeake Bay Joint Pollutant Reduction Plan
to increase stormwater retention from smaller storm events to promote sediment reduction and water storage for further nutrient uptake and slowly release larger storm events into the stream to help reduce possibly erosion associated with high peak flow rates.
Since these basins will be located directly next to the stream, the bottom of the basins will most likely be around groundwater level. This basin will then be considered to be a detention basin. This basin will still contain water quality plantings but will mostly be used to reduce rate of the runoff to the stream. The basins could provide additional floodplain capacity helping to reduce extreme flooding events seen by the areas affected by flooding of the stream.
BMP-200 Cemetery Road Detention Basins - The drainage from the adjacent cemetery and upland forested area drains to a low lying area adjacent to Cemetery Road. This project is aimed at creating a detention basin within this area to promote stormwater storage and reduce peak flow rate to the downstream system.
BMP-231 Lycoming Valley Middle School Infiltration Basin/Regenerative Stormwater Conveyance - The Township had identified an area near Lycoming Valley Middle School where wet weather problems persist. South of the school is a drainage path to an unnamed tributary to Lycoming Creek that could be converted into an infiltration basin and/or a regenerative stormwater conveyance system.
The proposed infiltration basin would provide a localized area of groundwater recharge and help to reduce both volume and peak flow discharge to its downstream drainage area. The regenerative stormwater conveyance portion would consist of regrading the channel to include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity and promote infiltration. The proposed infiltration basins/conveyance system could reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading, promote nutrient reduction, and reduce thermal impacts to the Lycoming Creek.
BMP-233 Fox Hollow Run Regenerative Stormwater Conveyance - The City had identified the Fox Hollow Run area as having limited wet weather capacity. Previous reports have indicated a need to provide conveyance or storage to assist in managing runoff. A portion the stream has been identified with potential to convert at least a 400 foot segment of Fox Hollow Run into a regenerative stormwater conveyance system.
The regenerative stormwater conveyance project would consist of regarding the channel to include various steps, pools, check dams, riffle features, and other in channel features to help reduce the conveyance velocity, promote infiltration, and increase floodplain volume. The proposed conveyance system will further reduce stormwater runoff volume, reduce runoff rate, reduce sediment loading, and promote nutrient reduction to the Susquehanna River.
BMP-L3 Downspout Disconnection Enforcement in Loyalsock - The Township presently requires residents to disconnect all downspouts from discharging directly onto roads and stormsewer systems. Residents are required to discharge rooftop leaders onto vegetative areas and towards areas designed to receive stormwater as feasibly possible. The Township and Williamsport Sanitary Authority (WSA) could work together to verify disconnections and require corrective actions where necessary. WSA already tracks similar information as part of the combined sewer overflow management program and could expand the program to its entire service area, including Loyalsock Township MS4 areas.
BMP-W3 Downspout Disconnection Enforcement in Williamsport - The City presently requires residents to disconnect all downspouts from discharging directly onto roads and into stormsewer systems. Residents are required to discharge rooftop leaders onto vegetative areas and towards areas designed to receive stormwater as feasibly possible. WSA already tracks similar information as part of the combined sewer overflow management program and could expand the program to its entire service area, including City MS4 areas.

Street Sweeping and Catch Basin Calculations
STREET SWEEPING CALCULATION
Impervious area of streets swept 26 times a year: Williamsport: 28.1 acres Loyalsock: 306.5 acres Swept Street Area x Pollutant Load TSS (lbs/yr) (area weighted load from Model My Watershed output) Williamsport: 28.1 acre x 1,963 lbs/acre = 55,201 lbs/yr Loyalsock: 306.5 x 1,438 lbs/acre = 440,747 lbs/yr Street Sweeping BMP effectiveness = 9% Crediting calculation Williamsport: 55,201 lbs/yr x 0.09 = 4,968 lbs/yr Loyalsock: 440,747 lbs/yar x .09 = 27,767 lbs/yr
CATCH BASIN CALCULATION
Williamsport: assume catch basins cleaned in same area as street sweeping 1x year Assume approximately 30% of street sweeping load removed through inlet cleaning 4,968 lbs/yr x 30% = 1,490 lbs/yr Dry weights will be verified according to expert panel protocols. Loyalsock: assume catch basins cleaned in same area as street sweeping 1x per permit cycle (20% of system per year) Assume approximately 30% of street sweeping load removed through inlet cleaning 27,767 lbs/yr x 20% x 30% = 1,666 lbs/yr Dry weights will be verified according to expert panel protocols.

Urban BMP Load Reduction Calculation Table
INSTRUCTIONS: Each row in the table below can represent either different areas of land use/cover within a single planning area (e.g., municipality), or different BMP drainage areas within a given planning area. If an individual planning area has multiple "developed land" types, each type can be represented in separate rows, with each row having the same "Project Name". If it is assumed that the planning area is being reated by one BMP system, then the "Treatment Depth" should be the same for each row. Similarly, a given planning area can have multiple "BMP drainage areas" (i.e., areas treated by different BMP systems). If a BMP drainage area has multiple "developed land" types, separate "land use areas" can be represented on separate rows, with each row having the same "Project Name". Also, the treatment depth should be the same for any row associated with the same Project Name. If runoff from a land use/cover type with NO impervious cover (e.g., Cropland) is treated by a BMP system (either existing or proposed), use the Manual Override (column M) to type in the treatment depth (in/imp. ac). Examples of various options for characterizing different types of project areas are provided in the "Example" spreadsheet that is also available for downloading from the Model My Watershed site.

Urban BMP Load Reduction Calculation Table
INSTRUCTIONS: Each row in the table below can represent either different areas of land use/cover within a single planning area (e.g., municipality), or different BMP drainage areas within a given planning area. If an individual planning area has multiple "developed land" types, each type can be represented in separate rows, with each row having the same "Project Name". If it is assumed that the planning area is being reated by one BMP system, then the "Treatment Depth" should be the same for each row. Similarly, a given planning area can have multiple "BMP drainage areas" (i.e., areas treated by different BMP systems). If a BMP drainage area has multiple "developed land" types, separate "land use areas" can be represented on separate rows, with each row having the same "Project Name". Also, the treatment depth should be the same for any row associated with the same Project Name. If runoff from a land use/cover type with NO impervious cover (e.g., Cropland) is treated by a BMP system (either existing or proposed), use the Manual Override (column M) to type in the treatment depth (in/imp. ac). Examples of various options for characterizing different types of project areas are provided in the "Example" spreadsheet that is also available for downloading from the Model My Watershed site.

1391.01 SHORT TITLE.
This Title shall be known and may be cited as the "City of Williamsport Stormwater Management Ordinance." (Ord. 6211. Approved 4-15-2012.)
1391.02 STATEMENT OF FINDINGS.
The City of Williamsport finds that:
(a) Inadequate management of accelerated runoff of stormwater resulting from development throughout a watershed increases flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of streams and storm sewers, greatly increases the cost of public facilities to carry and control stormwater, undermines floodplain management and flood control efforts in downstream communities, reduces groundwater recharge, threatens public health and safety, and increases non-point source pollution of water resour_ces.
(b) A comprehensive program of stormwater management, including reasonable regulation of development and activities causing accelerated runoff, is fundamental

to the public health, safety and welfare and the protection of people of the Commonwealth, their resources and the environment.
(c) Stormwater is an important water resource. Less runoff provides for increased groundwater recharge for water supplies and base flow of streams, which also protects and maintains surface water quality.
(d) Federal and State regulations require certain municipalities to implement a program of stormwater controls. These municipalities are required to obtain a permit for stormwater discharges from their separate storm sewer systems under the National Pollutant Discharge Elimination System (NPDES).
(Ord. 6211. Approved 4-15-2012.)
1391.03 PURPOSE.
The purpose of this Title is to promote health, safety, and welfare within the City of Williamsport and its watershed by minimizing the harms and maximizing the benefits described in 1391.02 of this Title, through provisions designed to:
(a) Meet legal water quality requirements under state law, including regulations at 25 Pa.Code, Chapter 93, to protect, maintain, reclaim and restore the existing and designated uses of the waters of this Commonwealth.
(b) Authorize a comprehensive program of stormwater management designated to preserve and restore the flood carrying capacity of Commonwealth streams; to preserve to the maximum extent practicable natural stormwater runoff regimes and natural course, current and cross-section of water of the Commonwealth; and to protect and conserve ground waters and ground-water recharge areas.
(c) Manage stormwater runoff close to the source.
(d) Provide procedures and performance standards for stormwater planning and management.
(e) Maintain groundwater recharge, to prevent degradation of surface and groundwater quality and to otherwise protect water resources.
(t) Prevent scour and erosion of stream banks and streambeds.
(g) Provide proper operations and maintenance of all permanent Stormwater Management (SWM) Best Management Practices (BMPs) that are implemented within the City of Williamsport.
(h) Provide standards to meet NPDES permit requirements.
(i) Encourage the provision or upgrade of stormwater BMPs for existing development.

General Provisions
1391.03
G) Facilitate the development of Chesapeake Bay nutrient credits for retrofit stormwater facilities or regulated activities that exceed the minimum nutrient reduction standards.
(Ord. 6211. Approved 4-15-2012.)
1391.04 STATUTORY AUTHORITY.
(a) Primary Authority. The City of Williamsport is empowered to regulate these activities by the authority of the Act of October 4, 1978, P.L. 864 (Act 167), 32 P.S. 680.1, et seq., as amended, the "Storm Water Management Act" and the (appropriate municipal code).
(b) Secondary Authority. The City of Williamsport also is empowered to regulate land use activities that affect runoff by the authority of the Act of July 31, 1968, P.L. 805, No. 247, the Pennsylvania Municipalities Planning Code, as amended.
(Ord. 6211. Approved 4-15-2012.)
1391.05 APPLICABILITY.
All regulated activities and all activities that may affect stormwater runoff, including land development and earth disturbance, are subject to regulation by this Title. (Ord. 6211. Approved 4-15-2012.)
1391.06 REPEALER.
Any other ordinance provision(s) or regulation of the City of Williamsport inconsistent with any of the provisions of this Title is hereby repealed to the extent of the inconsistency only. (Ord. 6211. Approved 4-15-2012.)
1391.07 SEVERAB ILITY.
In the event that a court of competent jurisdiction declares any section or provision of this Title invalid, such decision shall not affect the validity of any of the remaining provisions of this Title. (Ord. 6211. Approved 4-15-2012.)
1391.08 COMPATIBILITY WITH OTHER ORDINANCE REQUIREMENTS.
Approvals issued and actions taken under this Title do not relieve the applicant of the responsibility to secure required permits or approvals for activities regulated by any other code, law, regulation or ordinance. (Ord. 6211. Approved 4-15-2012.)
1391.09 EFFECT OF WATERSHED STORMWATER PLANS.
(a) After adoption and approval of a watershed stormwater plan in accordance with this act, the location, design and construction within the watershed of stormwater management systems, obstructions, flood control projects, subdivisions and major land developments, highways and transportation facilities, facilities for the provi-

acre that do not require hydrologic routing to design the stormwater facilities, this Title establishes no preference for either methodology; therefore, the applicant may select either methodology on the basis of economic considerations, the intrinsic limitations on applicability of the analytical procedures associated with each methodology, and other factors.
(a) The Design Storm Method (CG-1 in the PA BMP Manual) is applicable to any size of regulated activity. This method requires detailed modeling based on site conditions.
(1) Do not increase the post-development total runoff volume for all storms equal to or less than the 2-year 24-hour duration rainfall.
(2) For modeling purposes:
a. Existing (pre-development) non-forested pervious areas must be considered meadow or its equivalent.
b. Twenty percent of existing impervious area, when present, shall be considered meadow in the model for existing conditions for redevelopment.
(b) The Simplified Method (CG-2 in the PA BMP Manual) provided below is independent of site conditions and should be used if the design storm method is not followed. This method is not applicable to activities that disturb greater than 1 acre, or for projects that require design of stormwater storage facilities. For new impervious surfaces:
(1) Stormwater facilities shall be sized to capture at least the first 2 inches of runoff from all new impervious surfaces.
(2) At least the first 1 inch of runoff from new impervious surfaces shall be permanently removed from the runoffflow-i.e., it shall not be released into the surface waters of this Commonwealth. Removal options include reuse, evaporation, transpiration, and infiltration.
(3) Wherever possible, infiltration facilities should be designed to accommodate infiltration of the entire permanently removed runoff; however, in all cases at least the first 0.5 inch of the permanently removed runoff should be infiltrated.
(4) This method is exempt from the requirements of 1393.04, "Rate Controls." (Ord. 6211. Approved 4-15-2012.)
1393.04 RATE CONTROLS.
(a) Areas not covered by a release rate map from an approved Act 167 Stormwater Management Plan:

128
Post-development discharge rates shall not exceed the predevelopment discharge rates for the 1-, 2-, 5-, 10-, 25-, 50-, and 100-year, 24-hour, storms. If it is shown, that the peak rates of discharge indicated by the post-development analysis are less than or equal to the peak rates of discharge indicated by the pre-development analysis for 1-, 2-, 5-, 10-, 25-, 50-, and 100-year, 24-hour storms, then the requirements of this section have been met. Otherwise, the applicant shall provide additional controls as necessary to satisfy the peak rate of discharge requirement.
(b) Areas covered by a release rate map from an approved Act 167 Stormwater Management Plan:
For the 1-, 2-, 5-, 10-, 25-, 50-, and 100-year storms, the post-development peak discharge rates will follow the applicable approved release rate maps. For any areas not shown on the release rate maps, the post-development discharge rates shall not exceed the predevelopment discharge rates. (Ord. 6211. Approved 4-15-2012.)
1393.05 TECHNICAL DESIGN STANDARDS.
All regulated activities shall be conducted in conformance with the following standards:
(a) After installation of impervious cover, peak discharges for the 2-, 5-, 10-, 25-, 50-, and 100-year frequency storms from the site shall not exceed the respective peak discharge performance standards in this Title.
Stormwater runoff shall be managed so that no downstream increases in flood damages or impairment of streets and other public facilities occur. The City of Williamsport may require that downstream impacts be evaluat~d at critical locations such as dams, tributaries, existing developments, undersized culverts, and flood prone areas. The City of Williamsport shall make the final determination with respect tb the degree of management required for any site. The applicant shall evaluate the effects of the proposed plan on such critical locations by providing computed water surface elevations (WSEL) for the 10- and 100-year storms. Methods of computation shall have prior approval of the City of Williamsport. At such downstream critical locations, stormwater management may be exercised by:
(1) Providing off-site improvements to downstream conveyances in order to contain flow increases.
(2) Providing downstream drainage easements with sufficient widths to contain the flood limits.
(b) Groundwater Recharge. The City of Williamsport may impose stormwater quality measures in accordance with this Title to protect against ground or surface water pollution where the type of business or the nature of the stormwater runoff and soils underlying stormwater management facilities would constitute a substantial risk of contamination.

Plans for facilities other than storm sewers should determine stormwater peak discharge and stormwater runoff by the use of the PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended. The City of Williamsport may permit the use of the modified rational method or other methods for calculation of the storage capacity of a stormwater management facility from drainage areas of 20 acres or less.
(1) Coefficients. Acceptable runoff coefficient values for use in the rational method equation are identified in Appendix E, of this Title. When applying the rational method coefficients in Table A-3, "open space" coefficients shall be used for undeveloped, densely vegetated (non-forest) areas instead of "meadow" coefficients. Refer to PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended, for permissible curve numbers.
The Rational Formula may be used in lieu of the Soil Cover Complex method to compute design flows for the sizing of storm sewers, inlets, and swales.
(2) Rainfall amounts for the return periods specified shall be determined using the Precipitation-Frequency Atlas ofthe United States, Atlas 14, Volume 2 (as amended), U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Weather Service, Hydrometeorological Design Studies Center, Silver Spring, Maryland, 20910.

the given watershed and subwatersheds. In no case shall the duration be less than 24 hours.
(3) Time of concentration shall be determined in accordance with the methods presented in PennDOT Drainage Manual, Publication Number 13, DM-2 Chapter 10, as amended.
(4) In order to reduce stormwater runoff volumes from developed areas and encourage groundwater recharge, underground basin drains, infiltration trenches, and cisterns are permitted to which roof leaders may be connected. These drains consist of stone-filled basins which temporarily store and release water below ground surface. Plans for such facilities shall be submitted to the City of Williamspo1i for approval, and the basins shall be used only in those areas where soils, geologic, and water table conditions permit.
(e) Stormwater management facilities and related installations shall be provided:
(1) To permit unimpeded flow of natural watercourses. Such flow may be redirected as required, subject to the approval of the Pennsylvania Department of Environmental Protection.
(2) To ensure adequate drainage of all low points along the curb line of streets.
(3) To intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area drained, and to prevent substantial flow of water across intersections or flooded intersections during storms, in accordance with the procedures in the PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended.
(4) To ensure adequate and unimpeded flow ofstormwater under driveways in, near, or across natural watercourses or drainage swales. Suitable pipes or other waterways shall be provided as necessary.
(5) To properly drain stormwater runoff from all land development projects. All lot and open areas shall be designed to drain to the nearest practical street or drainage system, existing or proposed, as defined by the City of Williamsport, with no impact on adjoining properties, unless an area specifically designed for stormwater detention is provided.
(f) Storm sewers and related installations:
(1) Storm sewers, where required by zoning and land use densities, shall be placed under or immediately adjacent to the roadway side of the curb, or as directed by the City of Williamsport, when parallel to the street within the right-of-way.

The use of properly designed, graded, and turfed drainage swales is encouraged in lieu of storm sewers in commercial and industrial areas and, where approved by the City of Williamsport, in residential areas. Such swales shall be designed not only to carry the required discharge without excessive erosion, but also to increase the time of concentration, reduce the peak discharge and velocity, and permit the water to percolate into the soil, where appropriate. Criteria related to the use and design of drainage swales are as follows:
Criteria:
a. Where vegetated drainage swales are used in lieu of or in addition to storm sewers, they shall be designed to carry the 10-year discharge without erosion, and also to increase the time of concentration, reduce the peak discharge and velocity, and permit the water to percolate into the soil.
b. The maximum encroachment of water on the roadway pavement along roadside swales in cut areas shall not exceed half of a through traffic lane during a 10-year frequency storm of 5-minute duration. Frequent and/or sustained flooding of the sub-base shall be avoided.
c. Swales shall be designed in accordance with PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended. Inlets shall be provided to limit the shoulder encroachment and water velocity.
d. The side slope for any vegetated drainage channel requiring mowing of the vegetation shall have a maximum grade of three horizontal to one vertical on those areas to be mowed.
e. Erosion Prevention. All drainage swales shall be designed to prevent the erosion of the bed and bank areas. Suitable temporary and/or permanent stabilization during vegetative cover establishment shall be provided to prevent erosion.
f. Storm sewers or drainage swales shall discharge to a detention or retention basin to attenuate the peak rate and volume, respectively of stormwater runoff, except as provided in the plan.
g. Design Standard. Because of the critical nature of vegetated drainage channels, the design of all vegetated channels shall, as a minimum, conform to the design procedures outlined in the PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended.

a. Deed restrictions may be required on property(ies) containing drainage swales and/or perennial streams. When required, these deed restrictions shall specify that no property owner obstruct or alter any drainage swale or perennial stream identified in the stormwater management plan.
b. The design capacity of storm sewers shall be in accordance with PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended. Storm drainage systems shall be designed without surcharging inlets to provide conveyance of stormwater runoff into a detention basin or similar facility utilized to manage the rate of stormwater runoff. To avoid surcharging inlets, and to ensure that inlets will receive stormwater runoff, the hydraulic grade line at the inlet should be at least 6 inches below the elevation of the inlet grate. Where site grading will direct stormwater runoff from the 100-year design storm to a detention basin or similar facility utilized to manage the rate of stormwater runoff, then the storm sewer may be designed for the 10year design storm. Where site grading will not direct stormwater runoff from the 100-year design storm to a detention basin or similar facility utilized to manage the rate of stormwater runoff, then the storm sewer shall be designed for the 100-year design storm. Conveyance of storms to the detention basin, up to and including the 100-year frequency, shall be provided so as not to endanger life or seriously damage property.
c. Storm inlet types and inlet assemblies shall conform to the Pennsylvania Department of Transportation Standards for Roadway Construction as approved by the City of Williamsport.
1. Inlets shall, at a minimum, be located at the lowest point of street intersections to intercept the stormwater before it reaches pedestrian crossings; or at sag points of vertical curves in the street alignment which provide a natural point of ponding of surface stormwater.
2. Where the City of Williamsport deems it necessary because of special land requirements, special inlets may be approved.
3. The interval between inlets collecting stormwater runoff shall be determined in accordance with the PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended.
4. In curbed sections, the maximum encroachment of water on the roadway pavement shall not exceed half of a through traffic lane or 1 inch less than the depth of curb during the 10-year design storm of 5-minute duration. Inlets shall be provided to limit the encroachment of water on the pavement. When inlets

are used in a storm system within the right-of-way limits of a street in lieu of manholes, the spacing of such inlets shall not exceed the maximum distance of 450 feet.
5. The design of storm inlets shall be in accordance with PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended.
d. Accessible drainage structures shall be located on a continuous storm sewer system at all vertical dislocations, at all locations where a transition in storm sewer pipe sizing is required, at all vertical and horizontal angle points exceeding 5 degrees, and at all points of convergence of two or more influent storm sewer mains. The construction locations of accessible drainage structures shall be as indicated on the subdivision drainage plan or area drainage plan approved by the City of Williamsport.
e. When evidence available to the City of Williamsport indicates that existing storm sewers have sufficient capacity as determined by hydrograph summation and are accessible, proposed stormwater facilities may connect to the existing storm sewers so long as the peak rate of discharge does not exceed the amount permitted by this Article.
(g) Bridges and culverts shall have ample waterway opening to carry expected flows, based on the PennDOT Drainage Manual, Publication Number 13, DM-2, Chapter 10, as amended, or as required by the City of Williamsport.

Comments shall be received and. E&SPC plan approval obtained from the Conservation District prior to stormwater plan approval.
(n) Minor SWM Plan. A minor SWM plan is required per 1393.02(c) and as outlined in Appendix C. Minor SWM plans shall consist of the following, and are not subject to 1393 .03, "Volume Controls," and 1393 .04, "Rate Controls," of this Title. Minor plan preparation steps are as follows:
(1) Prepare a scaled drawing showing key features of the site.
The plan can be developed from a tax map, site survey, or other accurate drawing of the site. The property and boundaries should be accurate in scale. The plan should include:
a. A line showing the limit and location of area(s) that will be cleared for regulated activities such as buildings, driveways and lawns.
b. The location of all structures, existing and proposed (house, shed, garage, etc.). Include driveways, parking areas, any other impervious surfaces, well and septic system locations.
c. The location of property boundaries, any streams or wetlands, and separation distances of structure(s) to any water body or stream.
d. The angle/slope of the property in relation to any water body or stream.
(2) Calculate the volume of stormwater runoff created by the project.
Identify the newly created impervious areas. Note on the plan the area of each proposed structure and impervious surface (paved, walkways, etc.) and calculate the sum of the areas. For example:
a. 20' x 20' shed =
400 sf
b. 6' x 60' sidewalk =
360 sf
c. Total Impervious Area=
760 sf
(3) Calculate the volume of stormwater runoff.
For minor projects, multiply the total square footage of newly created total impervious area by (2.85 in/12 in/ft). For example:
760 sfx (0.2375 ft.)= 180.5 cubic feet
(2.85 in is the 2-year, 24-hour rainfall for Williamsport, PA, taken from NOAA's Hydrometeorological Design Studies Center Precipitation Fre-

quency Data Server for Point Precipitation Frequency Estimates from NOAA Atlas 14).
(4) Identify/choose the appropriate stormwater control measures. Size and place the measures on the project site, and add the measures to the SWM plan.
The volume of stormwater runoff calculated in Step #3 is now used to size the stormwater control storage devices. Vegetative controls and structural measures can be used individually or in combination to provide the required storage volume. The PA BMP Manual identifies structural and non-structural control measures that may be used, as well as instructions to calculate the volume provided by each.
Please note that all minor stormwater management plans should provide appropriate erosion control measures. Refer to subsection (m) above. The PA Erosion and Sediment Pollution Control Program Manual is available for guidance. Please contact the Lycoming County Conservation District for additional information.
A sample minor stormwater management plan can be found in Appendix D.
(o) All regulated activities that do not fall under the exemption criteria referenced herein shall submit a drainage plan to the City of Williamsport for review. These criteria shall apply to the total proposed development even if development is to take place in stages. Impervious cover shall include, but not be limited to, any roof, parking or driveway areas and any new streets and sidewalks. Any areas designed to initially be gravel or crushed stone shall be considered to be impervious for the purposes of comparison to the waiver criteria, unless they are installed and maintained as provided for in the PA BMP Manual.
(1) Stormwater drainage systems shall be provided in order to permit unimpeded flow along natural watercourses, except as modified by stormwater management facilities or open channels consistent with this Title.
(2) Areas of existing diffused drainage discharge shall be subject to any applicable discharge criteria in the general direction of existing discharge, whether proposed to be concentrated or maintained as diffused drainage areas, except as otherwise provided by this Title. If diffused flow is proposed to be concentrated and discharged onto adjacent property, the applicant must document that adequate downstream conveyance facilities exist to safely transport the concentrated discharge, or otherwise prove that no erosion, sedimentation, flooding or other harm will result from the concentrated discharge.
(3) Where a development site is traversed by watercourses, drainage easements shall be provided conforming to the line of such watercourses. The terms of the easement shall prohibit excavation, the placing of fill or structures, and any alterations that may adversely affect the flow of stormwater within any portion of the easement. Also, maintenance, including mowing of vegetation

within the easement shall be required, except as approved by the appropriate governing authority.
(4) When it can be shown that, due to topographic conditions, natural drainageways on the site cannot adequately provide for drainage, open channels may be constructed conforming substantially to the line and grade of such natural drainageways. Work within natural drainageways shall be subject to approval by PA DEP through the joint permit application process, or, where deemed appropriate by PA DEP, through the general permit process.
(5) Any stormwater management facilities regulated by this Title that would be located in or adjacent to waters of the Commonwealth or wetlands shall be subject to approval by PA DEP through the joint permit application process, or where deemed appropriate by PA DEP, the general permit process. When there is a question whether wetlands may be involved, it is the responsibility of the applicant or his agent to show that the land in question cannot be classified as wetlands, otherwise approval to work in the area must be obtained from PA DEP.
(6) Any stormwater management facilities regulated by this Title that would be located on State highway rights-of-way shall be subject to approval by the Pennsylvania Department of Transportation (PA DOT).
(7) Minimization of impervious surfaces and infiltration of stormwater runoff through seepage beds, infiltration trenches, etc., are encouraged, where soil conditions permit, to reduce the size or eliminate the need for detention facilities.
(8) In order to promote overland flow and infiltration, roof drains should not discharge directly to streets or storin sewers. Roof drains may discharge directly to streets or storm sewers when deemed necessary by the City of Williamsport. Under no circumstances shall roof drains discharge directly to sanitary sewer systems.

DISCONNECTED IMPERVIOUS AREA (DIA)
B.1. Rooftop Disconnection
When rooftop downspouts are directed to a pervious area that allows for infiltration, filtration, and increased time of concentration, the moftop may qualify as completely or partially Disconnected Impervious Area (DIA) and a portion of the impervious rooftop area may be excluded from the calculation of total impervious cover.
A rooftop is considered to be completely or partially disconnected if it meets the requirements listed below;
The contributing area of rooftop to each disconnected discharge is 500 square feet or less,
and
The soil is not designated as hydrologic soil group ''D" or equivalent, and
The overland flow path from roof water discharge area has a positive slope of 5% or less.
For designs that Uleet these requirements, the portion of the roof that may be considered disconnected depends on the length of the overland path as designated in Table B.1.

B.2. Pavement Disconnection
\Vhen pavement runoff is directed to a pervious area that allows for infiltration, filtration, and increased time of concentration, the contributing pavement area may qualify as Disconnected Impervious Area (DIA) and a that area may be excluded from the calculation of total iinpervious cover, This applies generally only to small or nruTow pavement structures such as driveways and nanow pathways through otherwise pervious areas (e.g. a walkway or bike path through a park).
Pavement is disconnected if the pavement, or area adjacent to the pavement, meets the requirements below:
The contributing flow path over impervious cover is not more than 75 feet, and The length of overland flow is greater than or equal to the contributing length, and The soil is not designated as hydrologic soil group "D" or equivalent, and The slope of the contributing impervious area is 5% or less, and The slope of the overland flow path is 5% or less.
If the discharge is concentrated at one or more discrete points, no more than 1000 square feet may discharge to any one point. In addition, a gravel strip or other spreading device is required for concentrated discharges. For non.concentrated discharges along the entire edge of pavement, this requirement is waived; however, there must be provision for the establishment of vegetation along tl1e pavement edge and temporary stabilization of the area until vegetation becomes stabilized.

ENFORCEMENT
102.31. Applicability.
The Department or a conservation district may enforce this chapter under The Clean Streams Law (35 P. S. 691.1--691.1001).
Authority The provisions of this 102.31 amended under sections 5 and 402 of The Clean Streams Law (35 P. S. 691.5 and 691.402); section 1920-A of The Administrative Code of 1929 (71 P. S. 51020); and section 11(2) of the Conservation District Law (3 P. S. 859(2)).

Immediately preceding text appears at serial pages (203744) to (203745).
Notes of Decisions The provision concerning a 25-acre requirement found in this section should be read so as to relate merely to permit requirements, not so as to remove parcels of land of less than 25 acres from the protection of erosion and sedimentation controls. Delaware County Community College v. Fox, 342 A.2d 468 (Pa. Cmwlth. 1975). The Department of Transportation does not come within the provisions of 25 Pa. Code 102.31 (a)(4) with its plan to construct culverts for stream crossings for an expressway project to be carried out in sections of 17 acres at a time. In re Precision Tube Company, Inc., 2 Pa. D. & C.3d 1 (1975). The Department of Transportation need not obtain an erosion and sedimentation control permit before commencing earth moving activity for construction of an expressway if the plan is developed with and approved by the Soil Conservation Service. In re Precision Tube Company, Inc., 2 Pa. D. & C.3d 1 (1975).
102.32. Compliance and enforcement provisions.
(a) Compliance and enforcement actions under this chapter which may be pursued include the following. The actions listed are cumulative and the exercise of one action does not preclude the exercise of another. The failure to exercise an action will not be deemed to be a waiver of that action:
(1) Investigations and inspections. (2) Response to complaints. (3) Orders (including orders to remediate or restore). (4) Civil penalty proceedings, except as provided in subsection (b). (5) Summary proceedings. (6) The suspension, revocation, withholding or denial of permits or approvals. (7) Notices of violation.
