STORM SEWER SYSTEM INFORMATION 2.1 Population Served: Winston-Salem is in the northwestern area of the Piedmont Region of North Carolina. Situated in Forsyth County, Winston-Salem is the fifth largest city in North Carolina and has an estimated population of 254,032 citizens (based on data from the World Population Review website, August 2024). 2.2 Growth Rate: The City of Winston-Salem increased its population size by 0.42 percent annually and 1.69 percent from the last U.S. Census, which was recorded in 2020. 2.3 Jurisdictional and MS4 Service Areas: The City of Winston-Salem does not have any ETJ areas currently. The square mile area for the city is 132.45. 2.3aLatitude of Center of MS4 Area: 36 degrees 06' 9.95"N Longitude of Center of MS4 Area: 80 degrees 15' 37.77"W 2.3bStorm Sewer Service Area(square miles): 132.45 2.4 Municipal Separate Storm Sewer System (MS4): The City of Winston-Salem is authorized to discharge stormwater from its municipal separate storm sewer system (MS4) into the waters of the State of North Carolina. A National Pollutant Discharge Elimination System(NPDES)permit is the legal mechanism that allows the City of Winston-Salem to discharge stormwater runoff into streams. All six minimum measures, which govern the City of Winston-Salem's Stormwater Program, are contained within this permit. The City of Winston-Salem is delineated into 17 different sub-watersheds that drain the City and its surrounding area. The streams, within these sub-watersheds, flow in a southwesterly direction into Lower Muddy Creek; the original fifteen watersheds had stormwater masterplans developed for staff by a consultant. Current objectives of masterplan efforts include providing a comprehensive update of the existing storm sewer inventory (contained within public, private, and industrial properties),perform stream-walking assessments and stormwater discharge outfall monitoring, and evaluate the impacts of stormwater discharges on the quality of Winston-Salem's streams. Information obtained from those plans show that Winston-Salem has approximately 538 miles of stormwater conveyance piping and 39,818 infrastructure devices, which includes catch basins and manholes. Based on the city's current GIS layer, there are approximately 547 miles of perennial and intermittent streams within the municipal boundaries of Winston-Salem. 2.4aMS4 maintenance activities: Cave-in reports are responded to within 24 hours of first knowledge of occurrence with simple repairs being completed within 72 hours. Maintenance activities include the following services of catch basin inspection and cleaning,pipe repair, replacement and upgrade projects, ditching (performed by hired contractors or in-house crews), and street sweeping activities are performed by in-house services. 7 2.5 Land Use Composition Estimates: The land use estimates below are from the City of Winston-Salem Planning Department(source: The Legacy 2030, Table 4-1, dated 2012) Land Use Classification Residential=43.14% Commercial=2.81 % Industrial =3.32% Parks/Open Space=2.09% Institutional=2.94% Right-of-Way= 8.15 % Office/Office Commercial=0.46% Agricultural = 15.71 % Vacant =20.97% Utility =0.41% TOTAL 100.0% 2.6 Estimate Methodology: Classifications are based on zoning districts with the corresponding acreage versus the total acreage of the City of Winston-Salem. For this assessment, schools have been calculated as institutional purposes and parks are listed separately (typically included in the residential classification). 2.7 TMDL Identification: The North Carolina Department of Environmental Quality(NCDEQ)has detected standard violations of turbidity and chlorophyll a at High Rock Lake, which is 25 miles south of Winston-Salem. A TMDL is currently being developed for wastewater point sources within the High Rock Lake Watershed, which indirectly receives stormwater discharges from the City's MS4. The main contributing river to High Rock Lake is the Yadkin River, in which Muddy Creek discharges into near the Forsyth-Davidson County border. NCDEQ determined that the Salem Creek Watershed is biologically impaired due to excessive fecal coliform concentrations. As a result, the Stormwater Division continues to perform water sampling to determine pollutant origin sources of fecal coliform loading into Salem Creek. The City of Winston-Salem revised its TMDL Sampling Plan in 2019, which resulted in 22 water sampling sites being selected throughout Salem, Peters, and Brushy Fork Watersheds. Stormwater staff will perform basic statistical analyses of collected water quality samples; once a sufficient population of data points exists to discern an observable trend, staff will report its findings to NCDEQ. In November 2011,NCDEQ issued a final report for turbidity impairment of the Muddy Creek Watershed. The Muddy Creek TMDL designates the City of Winston-Salem's MS4 as a significant contributor of turbidity (i.e. total suspended solids)pollution. A waste load allocation(WLA) was not assigned to the City's NPDES permit; however, total suspended solids loading (ton per a day) must be reduced by 58 percent. In accordance with its NPDES permit, the city must evaluate strategies and adapt BMPs to reduce TSS loading within the Muddy Creek Watershed. 8 3. RECEIVING STREAMS Major River Basin: Yadkin Pee-Dee Name and Identification Number of the Primary Receiving Streams and Impoundments: The following inventory receives stormwater runoff from the MS4 jurisdictional area.

EXISTING WATER QUALITY PROGRAMS Local Programs Water Supply Watershed Protection—The Salem Lake Watershed Protection Ordinance is in place to provide regulations, which protect drinking water quality in the Salem Lake Watershed. These regulations meet or exceed the minimum regulations established by the North Carolina Environmental Management Commission under the provisions of the Water Supply Watershed Protection Act of 1989. Floodway and Floodway Fringe Regulations—Winston-Salem has adopted floodway and floodway fringe regulations to control alteration of natural drainage patterns, control development and to ensure stream velocities are not significantly increased. Erosion and Sediment Control—The City of Winston-Salem and Forsyth County is a locally-delegated program that enforces the North Carolina Sedimentation Pollution Control Act of 1973. The Erosion Control Ordinance regulates certain land disturbing activities to control accelerated erosion and sedimentation to prevent the pollution of water and other damage to lakes and watercourses. NPDES MS4 Phase I Permit—The City was issued a new stormwater permit that became effective October 10, 2018. Program components include public education and outreach,public involvement and participation, illicit discharge detection and elimination, construction site runoff controls, post-construction site runoff controls, and pollution prevention and good housekeeping for municipal operations. Code Enforcement Section of the Neighborhood Services Division—Enforcement of the sanitation code relating to weeded lots, shrubbery, solid waste in yards and curbside trash. It also includes vector control in the storm drainage system, sanitary sewers (manholes), and along creek beds. 10 Other programs that support water quality within the City of Winston-Salem: 1.

TV and radio infomercials Best Management Practices (BMPs) for Public Education and Outreach 8.1(a) Describe Target Pollutants, Sources, and Audiences: The Stormwater Division uses three resources to identify and target pollutants of concern within local waterways of Winston-Salem: regulatory requirements, fixed interval stream sampling, and historical illicit discharge detection and elimination reports. Regulatory requirements are derived from Total Maximum Daily Loads (TMDL)that the City of Winston Salem must reduce waste load allocations to Muddy and Salem Creeks (currently, the High Rock Lake TMDL is pending). For the Muddy Creek TMDL, the pollutant of concern is turbidity(i.e., TSS). Most probable sources of turbidity(TSS) loading include construction sites, in-stream channel erosion, and active construction sites. Fecal coliform is the pollutant of concern from Salem Creek Watershed. Bacterial source tracking (BST) confirmed that sanitary sewer overflows,pet waste, and wildlife populations contribute to fecal coliform pollution. Once the High Rock Lake TMDL is approved, nutrients will be targeting pollutants of concern. Fecal coliform and turbidity pollution degrade biotic integrity, thus impairing the reproduction cycle of aquatic life within streams. The Stormwater Division performs quarterly, fixed interval sampling to determine pollutant exceedances (when compared to Water Quality Redbook Standards) within streams. Since samples are collected during various weather conditions (e.g., dry, during, and post storm event), an accurate assessment of target pollutants has been established. Since 2019, the Stormwater Division has observed City-wide trending sample data that consistently shows evaluated concentrations of numerous pollutants. These pollutants of concern consist of turbidity(i.e., TSS), fecal coliform, and nutrients 15 (i.e., total nitrogen, total Kjeldahl nitrogen, total phosphorus, and dissolved phosphorus). Probable sources of nutrient exportation include excessive residential and commercial fertilizer applications, sanitary sewer overflows, atmospheric deposition on impervious surfaces, industrial facilities, and commercial car-washing activities. Nutrient loading depletes available dissolved oxygen concentrations for aquatic life due to excessive algal blooms, thus affecting water resources. Scientific research has proven that litter and debris transport nutrients within our waterways. Litter and debris can also serve as surrogates for other pollutants due to being more visible and tangible to the public. Historical illicit discharge detection and elimination(IDDE) reports indicate that hydrocarbon oil and grease is the most frequently released pollutant of concern within the City of Winston-Salem. Automobile repair businesses, car salvage facilities, nonpoint oil spills/leaks on public streets, industrial entities, and commercial car-washing operations are sources of oil and grease pollution. Oil and grease float on the stream surface and obstruct sunlight into the water column, which is needed by aquatic fauna and flora. In addition, hydrocarbon oil and grease damage riverine habitat and sensitive spawning areas due soil adsorption. Since contaminated soil particles settle at the bottom of spawning beds, fish cannot reproduce and eventually, vanish from the stream. Stormwater staff determined that increased educational efforts were warranted concerning fats, oils, and cooking grease (FOG), since the Stormwater Division experienced a significant upward trend of IDDE incidents during FY 2022-2023. The commonality of FOG releases was due to poor housekeeping practices at various food service establishments (FSE) throughout the City of Winston Salem. The Senior Community Educator developed a waterproof poster of acceptable BMPs for restaurant employees to follow, thus the expected outcome of changing one's mindset of dumping spent cooking oil into the MS4. The posters were given to the Forsyth County Department of Health staff and the Utilities Industrial Waste Control Chemist for distribution purposes. This rugged waterproof poster can be placed near grease rendering bins for restaurant employees' ease of reference, in hopes of reducing or eliminating spills. All proper disposal BMPs are printed in English, Spanish, and Mandarin languages for effectively conveying information; the Stormwater Division provided its Stormwater Pollution Hotline phone number, in the event FOG reaches the City's stormwater conveyance system or receiving streams. The Stormwater Division has identified numerous audiences for public outreach and education activities due to their potential risk of releasing targeted pollutants. Residents use lawn care products, dispose of household hazardous waste, own pets, and perform routine maintenance on their cars. Materials have been developed targeting residents to educate them about lawn care, household hazardous waste disposal, pet waste, and automotive maintenance. Programs or workshops, such as Carolina Yards &Neighborhoods, address fertilizer and pesticide usage and pet waste. Other materials have been developed to address automotive maintenance for businesses and stormwater volunteer opportunities. The Hispanic population is a growing segment within the City of Winston-Salem. General stormwater pollution information has been developed for this demographic as well as translations of current outreach materials to reach the Hispanic community in Winston-Salem. School- age children participate in Creek Crawls, an in-stream learning-experience concerning water quality issues and the difference between healthy and impaired streams. The overall goal from extensive school-age children education is to influence adult behavior, thus eliminating pollution-enhancing practices. A Stormwater Inspector performs industrial inspections and assessments on prioritized, permitted facilities; these inspections concentrate on pollution prevention and good housekeeping 16 measures, which curtail exposure of pollutants to rainwater. Erosion Control staff performs face-to- face informal meetings to discuss and implement corrective measures for containing sediment on-site. The Stormwater Division works in collaborative efforts with Winston-Salem/Forsyth County Utilities to reduce sanitary sewer overflows and leaks by utilizing utility mailers, social media and press releases. 8.1(c) Informational Web Site: The Stormwater Division operates and maintains an informative website, https://www.cityofws.org/Stormwater, to achieve a heightened awareness of stormwater-related issues and/or events. Information is reviewed and updated as needed every three months or upon a significant event or issue. The Senior Community Educator promotes the website at presentations, media releases, or posting the web address on distributed public educational materials. Topics for web postings range from pollutant `factoids' to public involvement opportunities. The Stormwater and Erosion Control Divisions have publicized its contact information and the Stormwater Hotline/Helpline (CityLink) on the City of Winston-Salem's main webpage. Once on the City's homepage, a citizen can locate staff member's name, e-mail address, and telephone number within four clicks of a computer mouse. The contact information for CityLink is located at the bottom of every city webpage and at the top of the Stormwater and Erosion Control Divisions' webpages. 8.1(d) Distribute Public Education Materials to Identified User Groups: The City of Winston Salem distributes public educational materials that directly relates to specific, targeted audiences. The City creates communicative information for ranked pollutants of concern, such as floatables, fecal coliforms, oil and grease, sediment (i.e., total suspended solids), and nutrients. Educational materials (and opportunities) include brochures (paper and electronic),presentations, TV advertisements, social media posts, workshops, community events, and targeted mailings. The City of Winston-Salem performs mass media outreach activities throughout the local area works in conjunction with the Piedmont Triad Regional Council (via Stormwater SMART). Stormwater SMART develops TV and radio public service announcements, social media posts, digital advertisements, and brochures (paper and electronic) to supplement the City's own education and outreach efforts. To ensure the maximum educational effectiveness, the City correlates the informative technique to the targeted audience. For example, best management practices brochures are written in Spanish for Hispanic automobile repair shops, and FOG posters were translated into English, Spanish, and Mandarin. 8.1(e) Promote and Maintain a Stormwater Hotline/Helpline: In 2005, City Council commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem. Known to the public as CityLink, this communication center receives citizen-generated e-mails or telephone calls regarding stormwater-related items illicit within the City.

Neighborhood Assistance 20 9.1(a) Volunteer Community Involvement Program: The City of Winston-Salem has implemented the following programs to various degrees to promote volunteer opportunities and ongoing citizen participation: • Creek Week is a week-long series of events geared to engage the public and support water quality awareness. Events usually include Creek Crawls, guided paddles and nature walks, lunch and learn presentations, a community read and book discussion,professional development workshops, homeowner and resident workshops, special children and teen's programs at the public libraries, community clean-ups, water centered recreational activities, and other interactive programs. Creek Week occurred in March and organized by a committee of municipal, county, and non-profit organizations. • Creek Crawls are held with local school classes where the students visit a nearby creek to examine the water quality of the stream using water quality test kits and visual observations. Benthic macroinvertebrates are collected, examined, and discussed as to form an overall assessment of the water quality of the selected stream. Students are taught to collect water samples and to identify the macroinvertebrates collected based on provided keys as part of this `hands on' approach. • The Stormwater Division supports the Adopt-A-Stream Program with Keep Winston-Salem Beautiful to reduce litter, debris, and floatables in our waterways. Homeowner associations, companies, special interest groups, families, or other interested parties can request to Adopt-A- Stream in their area of interest. Interested parties will commit to conducting three clean-ups per year and the City will provide signage and debris removal after each cleanup. Keep Winston- Salem Beautiful also coordinates Adopt-A-Street and Adopt-A-Park Programs to reduce litter, debris, and floatables in our community. • Big Sweep is conducted every year in October to remove trash and debris from local waterways. • The Great American Clean-Up in Winston-Salem is conducted every year in April to remove trash and debris from local streets, parks, and waterways. • The Stormwater Division coordinates and oversees the Storm Drain Marking Program where volunteer groups place adhesive 'No Dumping, Drains to Creek' markers. Field Operations at City Yard aide in this programmatic function by placing markers at frequently cleaned storm drain locations. 9.1(b) Establish a Mechanism for Public Involvement: The City of Winston-Salem has three main mechanisms for public input on stormwater issues and input on the stormwater management program: City Council Committee meetings, Stormwater Appeals Board, and the City Link `suggestion and comment' service request. The City Council has established committee level meetings that citizens are invited to attend to discuss topics, including stormwater management issues. The City Council committee hears citizen input concerning stormwater management issues, as a result of the Public Works Committee's open comment period. Public Works Committee meetings are advertised on the City's website and are held the second Tuesday of every month. The Stormwater Appeals Board has been created to hear appeals if an owner, developer, engineer, or other party disagrees with the decision of staff City Link has instituted a citizen"suggestion and comment" service request that allows any citizen to suggest or comment, which relates to the Stormwater Management Program. These suggestions or comments are forwarded to the Department Head for review and action, if necessary. 21 9.1(c) Establish Hotline(s) or Helpline(s): In 2005, City Council commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem.

Best Management Practices (BMPs) for Illicit Discharge Detection and Elimination: 10.1(a) Maintain Appropriate Legal Authorities: The City of Winston-Salem has an illicit discharge, connection, and disposal ordinance that regulates the introduction of illegal pollutants to the City's MS4 and receiving streams. The ordinance was adopted by City Council in 2006. Stormwater staff possesses adequate regulatory authority to provide enforcement actions, which include enforcement mechanisms, such as issuance of notice of violations, levy civil penalties, and issue stop work orders. One can reference the City's Stormwater Illicit Discharges and Connection Ordinance, Chapter 75, at ARTICLE I. ILLICIT STORMWATER DISCHARGES AND CONNECTIONS 10.1(b) Maintain a Storm Sewer System Base Map: The City of Winston-Salem has entered into a professional services contract with HDR Engineering for major outfall identification as well as creation of a comprehensive stormwater system inventory. For FY 2023-2024, HDR finished the City's major stormwater discharge outfall inventory assessment. 25 10.1(c) Inspect/Detect Dry Weather Flows at MS4 Outfalls in Targeted Areas: Illicit discharge detection and elimination procedures are contained within the Stormwater IDDE manual, which was last revised in August 2024. The Stormwater Division's current standard operating procedures (SOPs) are based on the Center of Watershed Protection's 2004 technical manual. Staff has modified these SOPs for functionality and cost-effectiveness, as new technology and funding become available, the Stormwater Division will update and adopt new practices, as needed. In FY 2023-2024, HDR completed the City's dry weather screening of new and existing major outfalls as well as stream-walk selected stream segments in the Salem Creek, Peters Creek, Silas Creek, and Muddy Creek Watersheds, which were prioritized due elevated concentrations of fecal coliforms and total suspended solids. Stormwater staff tracked, identified, and eliminated all known illicit discharges. Stormwater staff collected dry weather water samples from outfalls and analyzed for ammonia, nitrate, pH, conductivity, fluoride, surfactants, and fecal coliforms to identify pollutant sources. 10.1(d) Employee Training: The Senior Community Educator distributes a web-based power point presentation and booklet to all current and new municipal employees (pertinent field staff) in order to increase the success rate of detecting illicit discharges to the MS4/receiving waters. All new municipal employees, who are not in administrative positions, are required to review a web-based power point presentation and booklet regarding IDDE detection and reporting during orientation. During FY 2023-2024, Marketing and Communications and Stormwater staff created and implemented an educational video regarding proper pollution prevention and goodhousekeeping practices for current City employees. All City employees were required to watch this video and answer six quiz questions -the city achieved an overall 76.3 participation percentage. Moving forward, all current City employees will be required to watch the PP & MGH video on an annual basis, if possible. 10.1(e) Maintain a Public Reporting Mechanism: Stormwater staff will continue working with the IS department for maintaining the most current up-to-date information that can be accessed on our city website in order to keep the public informed. The reporting mechanism that the Stormwater Division uses is called CityLink. Once known of the reported issue, staff has 24 hours to respond accordingly to the reported situation. When CityLink receives an issue, the Assistant Director, Stormwater Operations Supervisor, and Stormwater Analyst receive an automated notification from CityLink. From there, management assigns staff accordingly to respond within the allotted period. 10.1(f) Documentation of IDDE Activities: When staff investigates an illicit discharge activity, a discharge report is developed and filed by the investigating staff member, regardless of the outcome. If an illicit activity is discovered, staff prepares a Notice of Violation (NOV), as per the requirements of Chapter 75-11 of the City Code. The NOV is sent to the violator(s) via certified mail or signature verified delivery by staff. The NOV clearly states the violation, as well as any abatement activities required by the City. Upon successful completion of abatement activities by the violator, a notification is sent stating that the illicit activity has been resolved. Staff records all electronic copies of all correspondence,photos, mapping, civil penalty assessments, and sampling results pertaining to the IDDE activity for future reference. Staff documents all IDDE incidents on an spreadsheet as well as a NOV/IDDE GIS layer for accurately tracking elimination activities. The City's Citizen Service Request (CSR) system is the main documentation source to bridge the communication gap between Stormwater staff and citizens. From there, citizens can call CityLink and receive information updates. 26 10.2 Illicit Discharge Detection and Elimination Annual Reporting Task Items for FY 2023 —2024: 1. HDR performed dry weather screening of major stormwater outfalls within Salem Creek, Silas Creek, Muddy Creek, and Peters Creek Watersheds, as a component of the city's comprehensive MS4 inventory update. As of June 30, 2024, HDR Engineering staff has evaluated 33 major stormwater outfalls out of the estimated total 1,717 outfalls. 2. Stormwater staff responded to 62 illicit discharges/cases, which resulted in 11 Notices of Violations (NOVs)being issued. 55 percent of issued NOVs were permanently and successfully resolved within 30 days of initial violation issuance; 27 percent of NOVs were resolved within 60 days. As of October 2024, 100 percent of all IDDE cases have been successfully resolved for FY 2023-2024. 3. As part of the masterplan inventory update, HDR staff stream-walked a total of 4.7 miles of local waterways within the City of Winston-Salem to identify dry weather illicit discharges as well as performing major stormwater discharge outfall reconnaissance activities. 4. As part of the city's Good Housekeeping and Pollution prevention programs, new city employees were trained to identify and report illicit discharges. During FY 2023-2024, a total of 839 new city employees were trained in IDDE detection and notification methods. 5.

During FY 2023-2024, Stormwater staff notified DEQ, Winston-Salem Regional Office of one fish kill due to illicit discharges with local streams. In addition, no incidents of petroleum sheens were observed by Stormwater staff and reported to the Winston-Salem Regional Office of DEQ. 27 11. CONSTRUCTION SITE RUNOFF CONTROLS Objectives: 1. Reduce pollutants in stormwater runoff from construction activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development. 2. Provide procedures for public input, sanctions to ensure permit compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices, review of site plans, which incorporates consideration of potential water quality impacts, and procedures for site inspection and enforcement of control measures. 3. A locally delegated program that meets or exceeds the state requirements covering the jurisdictional area of the permittee complies with the required minimum of this section. 4. The City of Winston-Salem has been delegated by NCDEQ-DEMLR to establish a local erosion and sedimentation control program to administer the Sedimentation Pollution Control Act of 1973; stormwater NPDES permit requirements will be fulfilled using this existing program. Grading permits are required for land disturbing activities that are greater than(or equal to) 20,000 square feet for new single-family dwelling construction(or part of a larger common plan of development) or greater than 10,000 (or equal to) square feet for any non-exempt purpose (or part of a larger common plan of development). For single-family dwelling sites under 20,000 square feet(and not in a larger common plan of development), an executed erosion control affidavit is mandated, which stipulates the installation of minimal erosion control measures to prevent off-site sedimentation. 11.1 BMP Summary Table RESPONSIBLE BMP Measurable Goals FY FY FY FY FY POSITION/ 19-20 20-21 21-22 22-23 23-24 PARTY The local program mandates NCDEQ,DEMLR approved sediment&erosion control practices for construction activities disturbing more Erosion than 20,000 sq. ft.for Control/Floodplain Erosion and single-family dwelling Manager a Sediment construction or 10,000 sq.

Chapter 8, Section 8.4 of the Unified Development Ordinance regulates land disturbing activities within Forsyth County's boundaries (this includes the City of Winston-Salem). For additional information regarding the City's Sediment and Erosion Control Ordinance,please visit this link: Chapter 8, Section 8.4. 11.1(b) Plan Review Process: Chapter 8, Section 8.4 of the Unified Development Code, Section 8.4.4 (A.) states that no person shall initiate any land disturbing activity upon a tract without having an erosion control plan approved by the Director or a designee and without having purchased the applicable permit through the Inspections Division office. Section 3.2.7 (A.) states that any area exceeding 20,000 square feet in surface area on one tract for construction of a single-family dwelling or 10,000 square feet on one tract for any other non-exempt purpose must be permitted. To be permitted, Section 8.4.4 (A.) mandates the creation and submittal of an erosion control plan, Section 8.4.17 provides the submittal standards and criteria of erosion, and sedimentation control plans to be reviewed, approved, and installed. When finalized, development plans are submitted to the City of Winston-Salem for permit approval of land disturbing activities; Erosion Control staff determines regulatory compliance in accordance with the Sedimentation Pollution Control Act of 1973 and Chapter 8, Section 8.4 of the City of Winston-Salem Unified Development Ordinance. As a result, sediment control devices for construction activities are evaluated for capture of 75 percent of the 40- micron particle and larger. 11.1(c) Field Inspections, Complaint Response, and Enforcement Procedures: Site inspections are conducted by one of four qualified Erosion Control Inspectors, which are assigned to a specific section of Forsyth County. One Erosion Control Inspector is solely dedicated to inspecting single family dwelling erosion control compliance. Inspector responsibilities include plan review and approval, issuance of grading/erosion control permits for construction activities, conducting on-site inspections, and performing enforcement actions, when needed. Each inspector conducts approximately ten site inspections per week; however, the frequency of inspections will increase (as needed) for overall programmatic compliance. 30 Enforcement action provisions are described in Chapter 8, Section 8.4.20 of the City's Unified Development Ordinance (Chapter 8). The Erosion Control Section will not issue a grading permit for a development site unless the sediment and erosion control plan has been approved. Deviation from the approved plan will result in a Notice of Violation (NOV) issued by the Erosion Control Inspector with required corrective actions and a compliance due date for completion of corrective actions will be documented. Mitigation activities are enforced in the event off-site sedimentation damage is observed. NCDEQ, DEMLR receives a copy of every NOV that is issued by the Erosion Control Section and NCDEQ, DWR is notified if sedimentation damage is observed to a jurisdictional water body. If the required corrective actions are not resolved by the compliance due date, a monetary fine, Stop Work Order, and/or Injunction may be imposed on the developer and/or contractor. In addition, the Inspections Division may withhold any certificates of occupancy until absolute resolution has been achieved. 11.1(d) Notification to the Responsible State or Local Government Agencies that have Enforcement Capabilities for eliminating Construction Site Wastes: During the course of conducting field inspections, Erosion Control Inspectors assess construction waste practices, specifically, regarding potential adverse impacts to water quality. If Erosion Control staff determines that a contractor's poor housekeeping practices possess a threat to water quality, staff will notify the Winston-Salem Regional Office of NCDEQ, DEMLR, if the site has a NCG01000 permit or located within unincorporated area of Forsyth County. If the site is located within the jurisdiction of a MS4-permitted entity (e.g. Clemmons, Lewisville, Kernersville, etc.), the respective stormwater authority is notified. Any pollutants that are directly (or indirectly) discharged, disposed, or illicitly connected to storm drain systems (public or private-owned) or streams, which are located within the City of Winston-Salem's municipal limits, are monitored and enforced by the city's Stormwater Division. 11.1(e) Educational and Training Materials for Construction Site Operators: Erosion Control staff performs on-site and in-office educational discussions with licensed contractors, design professional, developers, and the general public as per service requests and/or issuance of violations. These educational discussions are very interactive and personal. Erosion Control staff provides guidance resources to contractors, developers, and the public by directing them to the City and NCDEQ- DEMLR's websites. Erosion Control staff has also compiled and distributes digital technical guidance and design criteria resources through email or print by request. 11.1(0 Public Information: In 2005, City Council and the City Manager commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem. Known to the public as CityLink, this communication center receives citizen-generated e-mails or telephone calls regarding illicit activity within the City or County. The public can access CityLink on the City of Winston-Salem's homepage of www.Cityofws.org.; it appears on the bottom portion of the website. The Erosion Control Section has been integrated into the CityLink system and implemented a response time of three working days. The Erosion Control Section has publicized its contact information on the City of Winston-Salem's main webpage. Once on the City's homepage, a citizen can locate each Erosion Control staff member's name, e-mail address, and telephone number within three clicks of a computer mouse. 31 In addition,by calling 1-866-STOPMUD, citizens can report violations of the Sedimentation Pollution Control Act of 1973. The Erosion Control Section responds to e-mails and received complaints from the hotline within three business days of first knowledge. 11.2 Eminent Domain Authority: The Erosion Control Section has an established procedure of requiring documentation of review and approval of a post-construction stormwater management plan by NCDEQ, DEMLR for all development activity within Forsyth County. Municipalities that are excluded from this policy include Winston-Salem, Kernersville, Clemmons, and Lewisville, since each municipality has its own delegated post-construction stormwater program. This protocol provides NCDEQ, DEMLR the opportunity to collaborate with the Erosion Control Division concerning the approval of a post-construction stormwater management plan within the county where no post- construction stormwater management program exists. 11.3 Construction Site Runoff Control Annual Reporting Task Items for FY 2023 —2024: 1. The Erosion Control Section reviewed all submitted erosion control plans and performed corresponding onsite inspections to verify compliance. Erosion Control staff reviewed 183 erosion control plans and performed 1,754 onsite inspections for verifying site compliance. 2. The Erosion Control Manager and Assistant Stormwater Director performed a comprehensive gap analysis of DEMLR's Soil Erosion and Sedimentation Control Model Ordinance. All missing language from both State Model Ordinances (dated 2020 and 2021) has been incorporated into the City/County Unified Development Ordinance, Section 8.4-Erosion Control. Currently, both Assistant City and County Attorneys are reviewing the Local Model Ordinance in preparation of performing work sessions with the City of Winston-Salem City Council and Forsyth County Commissioners. 3. Erosion Control staff issued 36 Notice of Violations (NOVs) during FY 2023-2024. The average compliance percentage of all active construction sites was 56 percent, which can be attributed to frequent, intense storm events as well as the record-setting sheer volume of construction within Winston-Salem/Forsyth County. As a result, Erosion Control Inspectors were unable to perform as frequent site inspections, thus decreasing the overall average compliance percentage from FY 2023-2024. 4. Erosion Control Inspectors have referred five construction site waste stream issues to the Winston-Salem Regional Office of NCDEQ, DEMLR(outside the municipal limits of Winston- Salem) and one to the Stormwater Division (inside city limits) to prevent pollutants from entering surface waters/MS4. 5. Erosion Control staff successfully resolved a total of 90 illicit sedimentation discharge/release claims, which are tracked through the City's RockSolid(i.e. Service Request) system, as an indicator of program effectiveness. 32 12. POST-CONSTRUCTION SITE RUNOFF CONTROLS Objectives: 1. Manage stormwater runoff from new development/redevelopment that drains to the MS4 and disturbs an acre or more of land surface, including projects less than an acre that are part of a larger common plan of development or sale. 2. Provide a mechanism to require long-term operation and maintenance of SCMs. 3. Ensure controls are in place to minimize water quality impacts. 4. Permittee shall not be required to apply post-construction site runoff controls to entities that are exempt from permittee's jurisdiction, including entities exempted under N.C.G.S. 113A-56. 12.1 BMP Summary Table BMP Measurable Goals FY FY FY FY FY RESPONSIBLE 19-20 20-21 21-22 22-23 23-24 POSITION/PARTY The City of Winston Salem adopted a Post- Post- construction Stormwater construction Control Ordinance in a Stormwater September of 2008.

The Stormwater Engineer holds regular meetings with developers to guide them through the permit process. 12.1(a) Post-Construction Storm Water Management Program: The Stormwater Division oversees and enforces the city's post-construction stormwater management program. The City of Winston-Salem has supplemented previous water supply watershed regulations with current post-construction regulations for Class 'C' waters to address stormwater runoff from new and re-developed sites. The current Post Construction Stormwater Management ordinance was adopted by the City Council on September 19, 2008, and this ordinance applies to all development within our jurisdictional area (municipal boundary). The City's Post-construction Ordinance can be located at https://library.municode.com/nc/winston- salem/codes/code of ordinances?nodeld=PTIIICOOR CH75STMA ARTIVPOCOST. Due to the recent implications of House Bill 488,various text amendments, text additions and deletions were approved by City Council after a public hearing on September 16, 2024. These include text amendments to Section 75-203(d), Section 75-402(a), Section 75-402(b), the addition of Section 75-402(c) and deletions and additions to Section 75-404. References to the "Stormwater Appeals Board"were also removed from the ordinance and replaced with "The Board of Adjustment"who will now hear and decide on matters such variance requests and approvals and appeals. This created text revisions and additions to Section 75-203 and Section 75-205. 12.1(b) Strategies,which include SCM's Appropriate for the MS4: Programs with development/redevelopment draining to Nutrient Sensitive waters: Drainage from the City of Winston-Salem ultimately flows to the Yadkin River, which is the main tributary for High Rock Lake. High Rock Lake has been classified as nutrient sensitive and currently has a TMDL in development for Chlorophyll A and turbidity. Currently, wastewater point sources are being considered for a waste load allocation(WLA)—not stormwater sources. Structural and non- structural SCMs will be utilized to address the requirements of 15A NCAC .0126 (10) (e). These SCMs will provide sediment removal, which ultimately reduces the nutrient inputs to receiving streams. Proper application and storage of fertilizers is being addressed through a Turf Management Certification, which is administered by the Stormwater Division and the Forsyth County Cooperative Extension Service in efforts to reduce nutrient loading to receiving streams. 34 Fecal Coliform Source Control: The City of Winston-Salem coordinates with the Forsyth County Department of Public Health to reduce fecal coliform due to failing/or failed septic tank systems. This process requires the property owner to either connect to the POTW or repair/replace the septic tank system to effective operations. The City/County Utilities Commission(CCUC)has an extensive capital improvement program to rehabilitate failing sections of the sewer collection system. Stormwater staff works closely with the CCUC to resolve sanitary sewer overflows during dry weather screening activities or received citizen complaints. In addition, the City of Winston-Salem has an enforceable ordinance that requires pet owners to pick up fecal matter within its municipal boundaries. Section 6-12 in the City of Winston- Salem's Municode contains the sanitation requirements for picking up dog feces, which is posted at https://library.municode.com/nc/winston- salem/codes/code of ordinances?nodeId=PTIIICOOR CH6ANFO S6-12SAREDO. Non-Structural SCM's: Currently, the City of Winston-Salem has implemented a comprehensive plan for growth—the Legacy Development Guide, which was adopted in 2012. Environmental quality is a key subject area, which is addressed with an objective to protect our local watersheds, wetlands, and streams. The City also has adopted local water supply watershed protection regulations, as required by NC DWQ. The Unified Development Ordinance regulates development in the Water Supply watershed areas of the City of Winston Salem. Development is subject to zoning restrictions, erosion control measures, floodplain management and low-density development provisions as they pertain to the water quality criteria of the Post-Construction Stormwater Control Ordinance such as recording of stream buffers where applicable and use of vegetative conveyances to the maximum extent practicable. Structural SCM's: The City of Winston-Salem's Post Construction Stormwater Management ordinance provides sizing and performance criteria for water quality SCMs. The City of Winston-Salem has also adopted the State's Stormwater Design Manual as a technical guide for designing structural SCMs within its jurisdictional area and thus for use in also providing sizing and performance criteria, in combination with the ordinance provisions. The ordinance addresses both low density and high-density development scenarios as regards water quality attenuation. Low density developments (less than 24 percent built upon area, or less than two dwelling units per an acre)must meet all the Minimum Design Criteria(MDC) of the NC DWR Stormwater Design Manual—Low Density Chapter, to the maximum extent practicable. Such items include but are not limited to recording of stream buffers where applicable and using vegetative conveyances to the maximum extent practicable. High density developments (greater than 24 percent built upon area and more than two dwelling units per acre) in addition to meeting all the low density non-structural SCM requirements, to the maximum extent practicable, must also provide structural SCM's. Any SCM or combination of SCM's that are considered primary SCMs per the Stormwater Design Manual and that can be effectively constructed in the Piedmont physiographic region may be approved by the Stormwater Engineer. In addition, the Post Construction Stormwater Management ordinance also includes a local requirement for water quantity standards if a development creates more than 20,000 square feet of new impervious area. If that is the case a development must either, (a) design structural SCMs to mitigate detrimental downstream effects of flooding and erosion in various design storm events, or in lieu of management 35 provide a"no adverse impact downstream study"if indeed a no adverse impact situation can be proven. 12.1(c) Deed Restrictions and Protective Covenants: The City of Winston-Salem, as previously mentioned, created, adopted, and implemented its post-construction ordinance on September 19, 2008. This ordinance includes comprehensive regulatory procedures to ensure compliance. Right of entry drainage and access easements must be granted to the City to inspect, monitor, maintain, repair, or to reconstruct the stormwater management system as necessary and these easements are referenced in the recorded Operation and Maintenance Agreements. Notice of violations, remedies, and monetary penalties are examples of regulatory tools contained within the post-construction ordinance that the Stormwater Division utilizes as enforcement mechanisms. For further reference, the City's Post- construction Stormwater Control Ordinance (Chapter 75, Article IV) can be located at this link: https://library.municode.com/nc/winston- salem/codes/code of ordinances?nodeld=PTIIICOOR CH75STMA ARTIVPOCOST 12.1(d) Operation and Maintenance Plan: Stormwater staff inspect approved water quantity SCMs (pre- 2008 post-construction ordinance adoption) as well as the Salem Lake Watershed(Water Supply IV Classification) SCMs on an annual basis. Next, Stormwater staff informs the owners of record of any deficiencies noted so that they may be addressed. Operation and Maintenance Agreements are required to be approved, recorded, and implemented for all the developments located within the Salem Lake Watershed area that require SCM(s) and the owners of such SCMs are bound to the terms of that agreement. The Planning Department maintains a spreadsheet that tracks all the developments and redevelopments that have been submitted to the Stormwater Division for review and compliance with the Post-construction Stormwater Management Ordinance. This spreadsheet includes a list of the development names, whether they are exempt from the ordinance and if exempt an explanation of why so, and if they are not exempt a description of what provisions of the ordinance they had to meet as in water quality—(low or high density), or water quantity, or both. This spreadsheet contains pertinent information, such as project submittal, review notes, date of permit issuance with corresponding number, the owners contact information of the stormwater management system, what developments we are currently still waiting on for as-built records to be submitted, what developments have submitted as-builts and hence are subject to submitting annual inspection and maintenance records, etc., so that Stormwater staff can efficiently check or reference any development and its criteria that may have been permitted, since the ordinance was adopted. The City also maintains "hard" files for all projects listed in this spreadsheet. SCMs, within the City limits jurisdiction and approved after the adoption of the post-construction ordinance, must have an Operation and Maintenance Agreement recorded as part of the post construction permit process that is binding on the SCM owner. The responsibility of SCM inspection and maintenance is placed on the designated SCM owner, or Homeowners Association/Property Owners Association, as applicable, who has signed the recorded Operation and Maintenance Agreement. The requirements for such inspections and maintenance are outlined in an Operation and Maintenance Manual that forms part of the overall Operation and Maintenance Agreement. Beginning after the certification of the as-built drawings for a permitted stormwater management system, the 36 system must be inspected per the frequency described in this agreement by a suitably qualified professional on behalf of the owner. The owner must keep all records of these inspections and any maintenance activities that may have been necessary and submit these records to the Stormwater Director for review on an annual basis. The Stormwater Director or his designee may carry out his own inspection to validate such submitted records. Developers of all structural SCMs approved in accordance with the Post-Construction Stormwater Management ordinance must provide a signed and notarized financial disclosure statement to the Stormwater Division as part of the permitting process. The developer in this statement agrees to set aside funds in an account, which will be held and controlled by the developer, that equal 10% of the construction cost of the SCM(s). These funds shall be set aside within 5 years of the completion of construction of the SCM's and the account and funds within it are to be used exclusively for the operation and maintenance of the SCM(s). The City also requires performance bonding or other cash securities, in accordance with the Salem Lake Watershed Environmental ordinance provisions, on SCMs proposed and located within the Salem Lake Water Supply Watershed area. 12.1(e) Educational materials and training for developers: Multiple training and information sessions were provided by Stormwater Division staff prior to and after the ordinance implementation in 2008. Educational materials provided include a permit application flowchart, example of design calculations and other supplementary information such as Operation and Maintenance Manual templates. These are available on the Stormwater Divisions website. The Stormwater Engineer and if needed the Stormwater Director, also make themselves regularly available to meet with developers at their request on an individual basis if they need guidance on permit policies and procedures before applying for a permit. The Stormwater Engineer is also a member of the City's Technical Review Committee (TRC) and attends in person meetings held on a weekly and monthly basis to explain the Post-construction Stormwater Management permitting process to applicants looking to develop or redevelop property within the City limits and Salem Lake Watershed. The Stormwater Engineer has on average three such meetings (individual plus TRC combined) on a weekly basis. The Stormwater Engineer fulfills multiple meetings and information requests from developers, owners, and citizens either by phone or e-mail on a weekly basis outside of the in-person meetings. The City maintains a website on the Stormwater Divisions webpage that addresses the city's post- construction permitting process as well as development requirements within the regulated Salem Lake Watershed area. This website is used as an educational tool available to all developers and SCM owners. The website contains items such as, a link to the Post Construction Stormwater Management ordinance, a link to the NC DWR Stormwater Design Manual website, the permit flow chart, a link to the permit application and checklists for submittal, templates for Operation and Maintenance Agreements and Manuals, design examples or SCMs, templates for inspections and annual compliance reports, a link to the electronic review submittal system and also a detailed FAQ section that attempts to address most, if not all of the questions that developers and SCM owners typically have. This website may be found at https://www.cityofws.org/794/Post-Construction-Stormwater-Management. 37 12.2 Post-Construction Annual Reporting Task Items for FY 2023 —2024: 1. The Stormwater Division has inspected 259 water quantity control SCMs during the past permit year. Please note: These devices were constructed prior to the adoption of the post-construction ordinance. These SCMs mainly consist of dry detention basins. a. The number of SCMs that are categorized as `poor' = 7 (2.7%) b. The number of SCMs that are categorized with minor issues =46 (17.8%) c. The number of SCMs with no deficiencies=206 (79.5%) 2. Between implementation of the Post-construction Stormwater Control Ordinance in September 2008 and up to the end of this current permit period, the Stormwater Division has permitted a variety of structural SCMs that were required for high density developments under the water quality provisions of the ordinance as well as meeting the ordinance quantity provisions. Please note that as per Section 12.5 these stormwater management systems are inspected and maintained by the owners' qualified representatives with records of such inspections and maintenance activities submitted annually to the Field Operations Director. The SCMs permitted along with the number of the SCMs are as follows: a.Wet Detention Basins= 77 b.Sand Filters =69 c.Bio-Retention Cells =29 d.Stormwater Constructed Wetlands = 1 e.Contech Storm Filter Systems= 10 f.Bay Filter System= 15 g.Infiltration Trench or other such Systems= 7 h.Permeable Pavement System= 5 i.Dry Detention Basins/Underground Management Systems= 90 j.Filterra Units= 1 In addition to these high-density developments in the same period, the Stormwater Division has also issued 121 permits for developments that were considered low density under the water quality provisions of the ordinance. No structural SCMs were therefore required,but these developments still had to meet the low-density provisions of the ordinance and the Stormwater design manual low density minimum design criteria. 3. During Permit Year of 2023 —2024, the following information summarizes post-construction activities performed by the Stormwater Division: a. The number of plans reviewed= 61 b. The number of developments requiring water quality SCMs= 15 c. The number of developments requiring water quantity SCMs= 17 d. The number of no adverse impact studies submitted in lieu of management for quantity control= 7 e. The number of developments meeting the ordinance water quality provision exemptions =29 f. The number of developments meeting the ordinance water quantity provision exemptions = 33 38 g. The number of developments grandfathered from the ordinance provisions based on a prior plan approval issued before the ordinance implementation in 2008, or, covered under a master stormwater management plan submitted and approved, since the ordinance implementation= 1 h. The number of low-density projects=13 i. The number of high-density projects= 15 j. Sum of water quality SCMs= 19 (4 Sand Filters, 9 Wet Detention Basins, 3 Bay Filter Systems, 1 Infiltration System, 1 Bio-Retention Cell and 1 Contech Filter Systems) 4. Sum of water quantity SCMs =22 (9 Wet Detention Basins, 4 Sand Filters, 4 Underground Management Systems, 1 Bio-Retention Cell, 1 Infiltration System and 3 Dry Detention Basins). 5. The Stormwater Engineer maintained a comprehensive inventory of municipally owned SCMs during FY 2023-2024. The last update to the inventory spreadsheet was October 11, 2024. Please reference Appendix G of this spreadsheet for detailed, site-specific information regarding the City's SCMs. 6. The City Attorney's Office was consulted concerning the potential to create a preliminary flow- process for executing municipal-owned SCM Operation and Maintenance Agreements and maintenance responsibilities. As of October 2024, no direction has been forthcoming from the City's Attorney's Office on this flow process. It should be noted that there has been a lot of staff turnover in the City Attorney's Office since 2022. Once direction is provided and finalized, the City's SCM Manual for municipal operations will be finished by the Stormwater Engineer. 39 13. POLLUTION PREVENTION and GOOD HOUSEKEEPING for MUNICIPAL OPERATIONS Obi ectives: 1. Prevent or reduce stormwater pollution from municipal operations that drain to the MS4 system. 2.

Subsequently, staff prioritized these municipal operations for SWPPP creation and implementation due to the magnitude and nature of activities that each municipal operation provides to the public. Since that time, the Stormwater Division provides professional services to City entities to create and implement BMPs for mitigating or eliminating exposure of pollutants to stormwater runoff. The following tables provide an overview of the City's progression in reducing stormwater pollution from municipal operations, as of November 23, 2020.

The Stormwater Inspector prioritizes municipal facilities for an inspection ranking (annual frequency),based upon internal evaluation criteria, such as site size, nature of operation business practices, chemical or product quantities and/or toxicity, spill history, general permit issuance or status, etc. Once the inspection ranking list is finalized, the Stormwater Inspector evaluates the potential of each municipal facility or operation to generate potential pollutants. If the municipal facility/operation has been issued a general stormwater permit, the Stormwater Inspector determines onsite conditions and SPPP compliance with permit requirements. Basic municipal operations or facilities receive an abbreviated stormwater pollution plan, which concentrates on facility inspections, spill response procedures, general site maps, and employee training. If needed, the Stormwater Inspector refers the municipal facility to a qualified consultant for creation of a spill prevention, control, and counter measure plan (SPCC), which complements SPPP requirements (but not to replace). The inspection process focuses on current best management practices (BMPs) of chemical/substances (e.g. salt, gasoline, soil, etc.) storage, waste disposal, outdoor processes (e.g. vehicle and equipment washing), material un/loading, and automotive-related activities. In addition, Stormwater staff evaluates the effectiveness of structural BMPs, stormwater discharge outfall(s) condition, off-site erosion, and recommends corrective measures and/or BMP implementation (nonstructural or structural) for the facility. All generated inspection reports are posted on an internal shared drive as well as hard copies that are delivered to the Field Operations Director, Mr. Keith Huff. The Stormwater Division retains an electronic copy and hard copies of completed inspection forms. 43 Once corrective measures have been installed or implemented, stormwater personnel verify BMP effectiveness. The last comprehensive revision to the city's municipal inventory database was completed in June 2022; an update was finalized by the Stormwater Division during FY 2023-2024 and is located at(G:\Industrial Inspection&Municipal Goodhousekeeping\MGH&PP Program\Municipal Facilities\Master Municipal.xlsx 13.1(c) Site Pollution Prevention Plans for Municipal Facilities and Operations: The Stormwater Division has identified 83 municipal facilities/operations that have the significant potential for generating polluted stormwater runoff. As of June 30, 2024, 62 municipal facilities/operations have implemented stormwater pollution prevention plans (SPPPs)to remove pollutant exposure to stormwater runoff (Tables 13.2 and 13.3). 21 municipal facilities/operations have been designated for site pollution assessments/inspections with SWPPP creation and implementation, if needed(Table 13.4). The Lowery Street Complex will be evaluated for vehicle-washing BMPs during the coming permit years. (G:\Industrial Inspection& Municipal Goodhousekeeping\MGH&PP Program\Municipal Facilities\Master Municipal.xlsx) 13.1(d) Spill Response Procedures for Municipal Facilities and Operations: For municipally owned facilities that are not required to apply for a NPDES stormwater permit, an abbreviated SWPPP has been created and implemented by City staff. A key component of this abbreviated SWPPP is spill prevention and response plan and procedures that are site-specific. SPPPs include site maps, facility inspections, GH and PM schedule, and SPPP certification. All SPPPs have site maps, facility inspections, good housekeeping and preventive maintenance schedule along with a SPPP certification. Each municipal operation/facility performs spill response training on an annual basis. Table 13.3 contains a list of municipal facilities/operations that have implemented an abbreviated SPPP. 13.1(e) Prevent or Minimize Contamination of Stormwater Runoff from all areas used for Vehicle and Equipment Cleaning: Upon inspection of each municipal facility or operation, structural and nonstructural BMPs are recommended for implementation. Stormwater staff promotes vehicle/equipment washing at the Lowery Street Complex. These washing bays discharge into an oil and water separator, which is connected into the sanitary sewer. Parking lots for abandoned vehicles will be evaluated for installation of an oil and water separator. If BMPs cannot be installed, the vehicle-washing activities will be performed in accordance with NPDES requirements; selected BMPs will be incorporated into an abbreviated SWPPP to reflect on-site practices and measures. 13.1 (f) Streets,Roads, and Public Parking Lots Maintenance: The Sanitation Department performs monthly, at a minimum, street sweeping events at the top four identified municipally-owned facilities with potential pollutants, since December 2021. These facilities include Fleet Services, Winston- Salem Transit Authority, the Sanitation Garbage Truck Parking Lot, and Streets Operations Truck and Stockpile Yard. Selected BMPs for potential implementation include other identified municipal facilities for street sweeping activities, enhanced MS4 trash and sediment removal due to procurement of new jet truck equipment, future issuance of condensed spill response plans and procedures for municipal facilities that have the potential of hydrocarbon releases, and the generation and adoption of a capital improvement plan for repair or rehabilitation activities for municipally-owned stormwater control measures, which receive inputs from public streets and roads. 44 13.1(g) Inspection and Maintenance (I&M) for Municipally-owned or Maintained Stormwater Control Measures (SCMs) and the Storm Sewer System: City Yard Field Operations has developed and implemented a comprehensive operation and maintenance (O&M)program for structural BMPs as well as the MS4. This O&M Program includes (but not limited to)these activities: • Street(right-of-way) structure maintenance (pipes and catch basins)—the Field Operations processes an average of 870 service requests annually resulting in over 1,835 work orders each year. These work orders address a wide variety of maintenance tasks from inlet cleaning to ditch reshaping to structural maintenance. • Street sweeping—the Sanitation Department ensures that the downtown business core streets are swept daily to remove pollutants from roadways. The Sanitation Department utilizes high efficiency vacuum street sweeper for maximum pollutant(e.g. trash, TSS, fecal coliforms, and nutrient)removal. In addition, numerous municipal facilities (e.g., Winston-Salem Transit Authority, Fleet Services, Sanitation Garage Truck Parking Lot, and Streets Operation Truck and Stockpile Yard)utilize high efficiency vacuum sweepers to remove any potential pollutants (oil and grease, TSS, fecal coliforms, and nutrients) at a designated service interval. • Structural SCMs maintenance: The Stormwater Engineer inspected all municipally owned SCMs to assess current site conditions in November 2021. Next, Stormwater staff created a prioritization plan for SCM repair or rehabilitation activities. Based on these results, the Field Operations Director will need to encumber a total of$4.90 million(approximate) to return the six municipally owned SCMs to their designed, operating condition. The capital improvement projects are designated for repair or rehabilitation services for Fiscal Years of 2025 to 2030; these water quality SCMs scored the overall rank of 13 (Lowery Street Sand Filters Restoration) to 24 (RJR Wetland Restoration). 13.1(h) Staff Training: A web-based power point presentation and booklet is mandatory for all current and new municipal employees, which are not administrative positions, to view and synthesize awareness information regarding good housekeeping practices as well as illicit discharge identification and detection. Once training has been completed, City departments record each employee's name and employee ID number for documentation purposes and submit these training logs to the Senior Community Educator. These educational materials serve for refreshing current employees' awareness of pollution prevention techniques. In 2021, the Senior Community Educator, Stormwater Operations Analyst, and the City's Marketing and Communications Department created a new training video that highlights proper pollution prevention& municipal good housekeeping practices for key City operations to eliminate pollutant exposure to the environment. A main topic in this video pertains to recognizing and reporting illicit discharges/dumping activities to Stormwater staff, so more incidents can successfully be resolve by Stormwater staff, thanks to 'rank and file' City team members. For FY 2023-2024, 76.3 percent of city employees viewed and passed a confirmation test of Stormwater's PP & MGH and IDDE training video. This educational video will need to be viewed by all City employees on an annual frequency for maximum memory retention. 45 13.20 Municipal Good Housekeeping and Pollution Prevention Annual Reporting Task Items for FY 2023-2024: 1. The Stormwater Operations Supervisor performed SPPP audits and inspections of the selected municipal operations or facilities: Fleet Services and Vegetative Management. This list is located at G:\Industrial Inspection&Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Issues to be Resolved_Current.xlsx. Based upon these inspections, the Stormwater staff recommended 83 BMPs for obtaining permit compliance as well as eliminating exposure of pollutants to rainwater. Please reference Appendix B of inspected facilities performed by Stormwater staff. 2. The Stormwater Engineer, Field Operations Director, and City Attorney's Office will create and implement a flow-process for ensuring proper maintenance and operation of all municipally owned stormwater control measures (SCMs).

This plan is located at: G:\City Yard Inspection& Maintenance Plan\I&M SOP 2021 Final Version 12.22.21.docx. 4. Newly hired City employees viewed the stormwater orientation video and received a copy of the handbook, Stormwater Runoff Municipal Good Housekeeping and Pollution Prevention. This will serve as a foundation to educate newly hired city employees regarding proper pollution elimination or mitigation practices as well as observing and report illicit discharges to the Stormwater Division. 839 city employees viewed and read the proper pollution prevention and municipal good housekeeping educational literature during FY 2023-2024. 5. The Stormwater Division provided funding to 3RC, a facility that collects, disposes, and/or recycles household hazardous materials in the City of Winston-Salem. During FY 2023-2024, 3RC recycled 367.61 tons of household hazardous waste, including e-waste. 10,086 residents used 3RC for their household hazardous waste disposal needs. 6. The Sanitation Division collected and composted leaves, vegetative material, and brush collection. 30,515.21 tons of vegetative material was collected and composted by the Sanitation and Utilities Departments. 7. City Yard Field Operations removed and disposed trash and debris from the city's right-of-way stormwater collection system. During FY 2023-2024, Field Operations inspected and cleaned 23,987 MS4 structures within the city's right-of-way. 8. The Sanitation Division continued to perform streets sweeping activities within the municipal limits with increased efforts directed to the Downtown business core. 1,858 linear miles were swept during FY 2023-2024, according to the Sanitation Director, Mr. Stevie Dulin. 9. The Sanitation Division performed 18 street sweeping events at municipal facilities during FY 2023-2024. Based on estimated available open space of these facilities, the Sanitation Department swept approximately 234 total acres of municipally owned impervious area. 10. For FY 2026-2027, the Field Operations Director will attempt to procure budgetary funding to hire a professional engineering firm for creating stormwater pollution prevention plans of several identified municipal operations/facilities (Table 13.4). 46 14. MONITOR and EVALUATE STORMWATER DISCHARGES to MUNICIPAL SYSTEMS Objective: 1. Evaluate pollutants in stormwater discharges to the permittee's MS4 from hazardous waste treatment, disposal and recovery facilities, industrial facilities subject to Section 313 of Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA), and industrial facilities that the Permittee determines are contributing or having a potential to contribute a substantial pollutant loading to the municipal storm sewer system. 14.1 BMP Summary Table BMP Measurable Goals FY FY FY FY FY RESPONSIBLE 19-20 20-21 21-22 22-23 23-24 POSITION/PARTY A complete list has been generated and updated by the Stormwater Division.

This list consists of industrial facilities that are permitted as defined by 40 CFR 122.26, SARA Title III, hazardous waste facilities, or identified as having or had an illicit discharge. The Stormwater Division updated this master list on July 19, 2024. All data will be stored digitally in our database and will be updated semiannually to maintain the most current inventory. This information can be located at: G:\Industrial Inspection & Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Master Industrial Spreadsheet\Industrial Master.xlsx. 14.1(b) Inspection Program: Our current techniques are based upon revised 2006 EPA inspection methods, which include observations of effectiveness of nonstructural and structural BMPs, the facility's stormwater collection system and stormwater discharge outfalls, site maps, and validation of written SPPP information to actual field observations. The City of Winston-Salem has prioritized industrial facilities within its municipal limits to be inspected. The Stormwater Division used the following sources to generate the list: 1. EPA's Envirofacts Database for Toxic Release Inventory (SARA Title III) and RCRA (hazardous waste treatment, disposal, and recovery) facilities (updated semiannually) 2. NC Department of Energy, Mineral and Land Resources Database (General and Individual Permitted industrial facilities, as per 40 CFR 122.26) (updated semiannually) 3. The City of Winston-Salem Facilities' Database (municipal operations/facilities that are permitted under 40 CFR 122.26) (updated semiannually, or as needed) 4. Illicit Discharge Reports (updated as needed and after each occurrence) When combining the above-mentioned databases, facilities that appeared multiple times due to their industrial activities and governmental regulations were ranked. As a result, the Stormwater Division assigned these industrial facilities with a high priority ranking due to the elevated probability of significant adverse impact to surface waters. The Stormwater Inspector will target these facilities for inspections. Appendix B contains industrial and municipal facilities that were inspected during FY 2023-2024 by the Stormwater staff. 14.1(c) Evaluate Industrial Facilities discharging stormwater to the City's MS4: During the SPPP review, Stormwater staff evaluates first flush data regarding benchmark values from the NPDES permit to determine to status before arrival. Once onsite for an inspection, a visual field observation of the stormwater collection system, current and past conditions of stormwater discharge outfalls (by means of qualitative monitoring records), and effectiveness of nonstructural and structural BMPs are observed. If needed, Stormwater staff will request copies of each sampling event to monitor results based upon the status of the permitted facility. Stormwater staff will update the master list to identify if the permitted facility is located within a TMDL watershed and/or discharges the TMDL pollutant of concern. The Stormwater Division maintains a good working relationship with the NC Division of Energy, Mineral and Land Resources (DEMLR), Winston-Salem Regional Office. A copy of every 48 completed inspection and re-inspection form must be forwarded to Tamera Eplin, Regional Engineer, who handles stormwater related duties for the Winston-Salem Regional Office (WSRO). 14.2 Monitor and Evaluate Stormwater Discharges to Municipal Systems Annual Reporting Task Items for FY 2023 —2024: 1. The Stormwater Inspector conducted five inspections/reinspections of permitted industrial facilities that discharge stormwater runoff to the City's MS4. Three facilities successfully achieved compliance, as of June 30, 2024. Three facilities are in a status of`pending' since time extensions were granted by the Stormwater Operations Supervisor. This information is located at: G:\Industrial Inspection& Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Issues to be Resolved.xlsx. Please reference Appendix B of inspected facilities performed by Stormwater staff. 2. All completed inspection forms of general permitted facilities, which was performed by the Stormwater Operations Supervisor, was sent electronically to the Winston-Salem Regional Office of NC DEQ. As a result, the Stormwater Division reported all inadequate, tiered responses,based on the reviewed data and BMPs, if applicable, to DEQ. 3. During FY 2023-2024, the Stormwater Operations Supervisor examined four industrial facilities within designated TMDL watersheds. This information is located at G:\Industrial Inspection& Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Inspections.xlsx 4. The Stormwater Inspector updated the Stormwater Division's industrial inventory master list on July 19, 2024. The Stormwater Inspector downloaded applicable facilities from EPA's Envirofacts Database regarding Toxic Release Inventory, the Resource Conservation and Recovery Act (hazardous waste treatment, disposal, and recovery), and general and individual stormwater permitted facilities from DEQ's website. Once downloaded, the database lists are consolidated and compared to the city's existing master list—any absence facilities are included into the city's master list. The city's current industrial inventory is located at G:\Industrial Inspection&Municipal Goodhousekeeping\Indust—Inspect\City Industrial Information\Master Industrial Spreadsheet\Industrial Master.xlsx. 49 15.

The Water Quality city of Winston- b Monitoring Salem's Water x x x x x Stormwater Quality Assessment Technicians and Monitoring Plan was revised and submitted to Stormwater Inspector DEMLR on October 6,2020,for approval. 15.1(a) Fixed Interval Stream Sampling Program: Water quality samples are collected on a quarterly, fixed interval basis at each monitoring site— 13 monitoring locations have been strategically selected throughout the municipal boundaries. Samples are collected in a composite method, except for fecal coliforms, which is a grab sample in accordance with 40 CFR 136.3. Composite samples are collected every 15 minutes in 100 milliliter aliquots for a 24-hour period. Parameters analyzed by a multiparameter meter are immediately obtained and recorded streamside. Appendix C contains all tabular data from the city's fixed internal sampling program;Appendix D provides maps of these sampling locations. This can be found at the following location: G:\Techn_Projects_Files\Water Sampling\Stormwater Sampling Databases. 15.1(a) Water Quality Monitoring Program: On a quarterly basis, Stormwater staff collect instantaneous results at 17 monitoring locations, which have been strategically selected throughout the municipal boundaries of Winston Salem. The overarching goals of this monitoring program are detection of 50 illicit discharges/releases as well as evaluating the long-term trend analysis of baseline water quality within non-TMDL watersheds. Samples are collected in dry and wet weather conditions to detect point sources of illicit discharges as well as determining pollutant loading during all weather conditions. Stormwater staff collects instantaneous water meter parameters, which include pH (standard units), dissolved oxygen saturation percentage, dissolved oxygen (mg/L), temperature (degrees Celsius), conductivity (microsiemens per a centimeter), total dissolved solids. The parameters of ammonia(mg/L), and nitrate (mg/L) are collected by Stormwater staff, then analyzed at a North Carolina certified laboratory. This can be found at the following location G:\Techn Projects_Files\Water Sampling\Stormwater Sampling Databases. 15.1(a) TMDL Monitoring Program: On a quarterly basis, Stormwater staff collects instantaneous water quality parameters (the same parameters listed above) as well as laboratory grab samples of fecal coliforms at 22 strategic locations throughout Brushy Fork Creek, Peters Creek, and Salem Creek Watersheds. By collecting a large population of samples, Stormwater staff will be able to rank impaired stream segments by fecal coliform concentrations. Once stream segments are ranked, staff will systemically sample and identify the most impaired outfalls or subbasins for the potential of installing stormwater control measures. The City collects samples in both dry and wet weather conditions, since the state collected and analyzed fecal coliforms during these conditions for TMDL development. This methodology will allow Stormwater staff to perform comparative analyses for evaluating pollutant loading. Appendix E contains all TMDL monitoring data for FY 2023-2024 in tabular form. 15.2 Water Quality Assessment and Monitoring Annual Report Task Items for FY 2023-2024: 1. Stormwater staff performs quarterly, fixed interval sampling at 13 locations throughout Winston- Salem for pollutant perimeters of BOD, TSS, TDS, Turbidity, Cd, Cr,Ni, Pb, Total &Dissolved Cu, Total & Dissolved Zn, Total & Dissolved P,NH3,NO2,NO3, TKN, TN, and fecal coliforms. Stormwater staff collected 1,038 water samples that were analyzed at a NC certified laboratory. 2. During FY 2023-2024, Stormwater staff collected 4,007 water samples with certified laboratory analyses and 3,175 water samples were collected within Salem, Brushy Fork, and Peters Creek Watersheds. 3. Stormwater staff will continue to perform quarterly water quality monitoring at 17 locations for the instantaneous results of ammonia, pH, and dissolved oxygen saturation percentage, dissolved oxygen, temperature, conductivity, total dissolved solids, and nitrate. Stormwater staff collected and analyzed 1,510 instantaneous parameters via portable YSI and Hach multiparameter meters during both dry and wet weather conditions. 4. Stormwater staff will continue to perform TMDL monitoring at 22 locations for the instantaneous parameters of ammonia, pH, and dissolved oxygen saturation percentage, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate. Total suspended solids and fecal coliforms parameters are analyzed at a North Carolina certified laboratory. Stormwater staff collected and analyzed 5,371 instantaneous and certified laboratory parameters in Salem, Peters, and Brushy Fork Creek Watersheds during dry and wet weather conditions. 51 16. TOTAL MAXIMUM DAILY LOADS (TMDLs) Salem Creek Watershed TMDL Obi ectives: 1. The permittee shall determine whether the MS4 discharges to receiving waters within a TMDL watershed and identify the pollutant(s) of concern (POC). For all TMDLs with a NPDES MS4 regulated stormwater waste load allocation (WLA) assigned to the permittee, the permittee shall determine whether the POC have potential to occur in MS4 stormwater discharges. 2. The permittee will utilize BMPs within the six minimum measures and the permittee's TMDL Plan(s) to meet the permittee's assigned NPDES MS4 regulated WLA identified in the approved TMDL to the maximum extent practical and to the extent allowable by law. 3. If subject to an approved TMDL with a NPDES MS4 regulated WLA assigned to the permittee, the permittee will be considered in compliance with the TMDL if the permittee complies with the conditions of this permit, including developing and implementing appropriate BMPs within the six minimum measures to address the permittee's MS4 NPDES regulated WLA to the maximum extent practical (MEP). While improved water quality is expected outcome, the permittee's obligation is to implement BMPs designed to address the NPDES MS4 regulated WLA assigned to the permittee to the maximum extent practical (MEP). The permittee is not responsible for attaining water quality standards (WQS). The Division expects attaining WQS will only be achieved through reduction from all point and nonpoint source contributors identified in the approved TMDL. TMDL Plans (as it pertains to the city of Winston-Salem's approved plan): 1. If the permittee has an existing TMDL Plan designed to address the NPDES MS4 regulated WLA assigned to the permittee, that includes monitoring to evaluate progress, and which addresses the POC through the six minimum control measures; it satisfies the objectives of this Section. 16.1 Salem Creek Watershed TMDL BMP Summary Table BMP Measurable Goals FY FY FY FY FY RESPONSIBLE 19-20 20-21 21-22 22-23 23-24 POSITION/PARTY A comprehensive master plan update of Salem, Field Operations Director Brushy Fork,and Peters Identify, Creek Watersheds was in Describe,and 2011.

GIS data was collected for these TMDL watersheds; survey-grade stormwater MS4 attribute data(e.g. structure type and elevation, pipe diameter and material, etc.) is collected by a contracted North Carolina Registered Surveyor. A consultant, HDR Engineering, performs QA/QC measures on the survey data, extrapolates pipe elevations to integrate flow directional trajectories for tracking IDDE discharges, and then, delivers a complete geodatabase to the Stormwater Division. During this inventory scan, the surveyor and HDR staff collects major discharge outfall (SDO) and stream data. If HDR staff encounters any dry weather flows at major SDOs, the Stormwater Division is notified, and staff evaluates the unidentified flow for pollutants. If pollutants are detected, Stormwater staff tracks and eliminates the illicit source. In addition, the Stormwater Division received hydraulic and hydrological modeling data as well as pollutant loading data for future SCM implementation projects. During FY 2022-2023 and 2023-2024, HDR incorporated screening tools to characterize potential fecal coliform and sediment sources in the most impaired stream segments in TMDL watersheds (or major tributaries). 16.1(b) Existing Measures: The City of Winston-Salem has implemented various stormwater control measures (SCMs) and nonstructural BMPs to reduce fecal coliform loading within the Salem Creek Watershed. During FY 2023-2024, the Stormwater Division continued to maintain these programmatic SCMs/BMPs: 54 Existing Measures Status Explanation to Reduce Pollutant of Concern Central District PTRP Wet Pond— Designed to remove 85 percent TSS captures first flush of runoff from the 100 percent complete— removal from influent,since fecal coliforms adjacent Piedmont Triad Research Park.

One of the salient points of the review included the lack of a substantial fecal coliform data population. As a result, the Stormwater Division designated 22 in-stream monitoring locations throughout Salem, Peters, and Brushy Fork Watersheds. Stormwater staff collects water quality samples on a quarterly frequency; for FY 2023- 2024, Stormwater staff collected 385 fecal coliform samples during dry and wet weather conditions. As more data becomes available, Stormwater staff will perform basic statistical analyses to rank the stream segments by the level of impairment (i.e., the higher the geometric mean at the sampling location, the increased level of pollutant loading). A preliminary stream ranking order is included in this report. As more data is collected, the Stormwater Division will perform annual trend analysis to observe increasing, decreasing, or constant fecal coliform concentrations within Brushy Fork Creek, Peters Creek, or Salem Creek Watersheds. 16.1(d) TMDL Monitoring Program: On a quarterly basis, Stormwater staff collects instantaneous water quality parameters (dissolved oxygen- concentration and percent saturation, total dissolved solids, conductivity, temperature,pH, nitrate, and ammonia) as well as certified laboratory results of fecal coliforms at 22 strategic locations throughout Brushy Fork Creek, Peters Creek, and Salem Creek Watersheds. By collecting a large population of samples, Stormwater staff will be able to rank impaired stream segments by fecal coliform concentrations. Once stream segments are ranked, staff will systemically sample and identify the most impaired outfalls or subbasins for the potential of installing stormwater control measures. The city collects samples in both dry and wet weather conditions, since the state collected and analyzed fecal coliforms during these conditions for TMDL development. This methodology will allow Stormwater staff to perform comparative analyses for evaluating pollutant loading. 57 16.1(e) Additional Measures: The City of Winston-Salem anticipates the implementation of numerous nonstructural BMPs to expand current pollutant reduction strategies within the Salem Creek Watersheds. By expanding current BMP strategies to the maximum extent practical, the Stormwater Division hopes to benefit from synergic pollutant reductions within the targeted watershed. The following matrix presents expanded measures (with corresponding explanations)to reduce fecal coliform loadings within the Salem Creek Watershed: Additional Measures Explanation of Designed Measures to Achieve Responsible Staff for MS4's NPDES WLA to the MEP Implementation By evaluating current business practices,the Stormwater Division wishes to provide local Perform Goodhousekeeping shelters with new or modified cleaning methods to Awareness Education with prevent or eliminate fecal coliform exposure to the Senior Community Educator local animal shelters open environment.Please note, due to the Educator position vacancy, this measure has been temporarily suspended.

The methodology used for documenting measure success (and ultimately, wasteload reduction) depends on measure type (i.e. nonstructural and structural). However, the Stormwater Division has proposed the below-posted means for validating pollutant reduction loading to the effectiveness of implemented control measures. These methods include: • Perform water quality sampling for targeted pollutants at the inlet and outlet points of a SCM during the first flush portion of a storm event. Once a SCM is constructed and operational, Stormwater staff will perform, at a minimum, one confirmation sampling event, to validate pollutant reduction. The pollutant removal efficiency will be recorded on a spreadsheet; an annual pollutant reduction will be extrapolated for the SCM. 60 • Continue to submit completed workload data and programmatic task items to DEMLR via the Annual Report. • Long-term, in-stream pollutant data will need to be collected, at designated sampling locations, to observe pollutant deductions in wasteload allocation reductions within subwatersheds. Due to the dynamic nature of biological ecosystems as well as the large percentage of pollutant reduction required, the Stormwater Division needs a substantial data population to observe percent reductions. As the number of SCMs/BMPs increases within a subwatershed, the Stormwater Division anticipates that the observable, pollutant trend line should decrease. • Whenever possible, use scientific journal articles (or similar professionally peer-reviewed literature), quality controlled/assured laboratory analyses (from a North Carolina certified laboratory), or professional engineered-sealed material when validating reduction methodologies for this TMDL Implementation Plan. Any best professional assumptions must be qualified with footnotes within supporting documents. 16.2 Salem Creek Total Maximum Daily Load(TMDL) Annual Report Task Items for FY 2023-2024: 1. 6,0511inear feet of restored drainage ditches within the City of Winston-Salem (and contributing tributaries) for total suspended solids reduction. 2. During TMDL sampling, instantaneous results of ammonia, pH, and dissolved oxygen percent saturation, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate are collected. This information is located at ..\Water Sampling\Stormwater Sampling Databases\Current\Complete Stormwater Sampling Database_Current.xls. Stormwater staff collected 1,386 instanteous meter results with 100 percent of all detected illicit discharges were eliminated. 3. HDR staff walked 4.7 miles of streams within Salem Creek, Peters Creek, and Brushy Fork Watersheds during dry weather conditions -no major outfalls were suspected of potential illicit discharges,based on qualitative and multiparameter meter results. 4. The Stormwater Division is furnishing all FY 2023-2024 fecal coliform data from all 22 TMDL sampling locations. This data set is contained in Appendix E. 5. Stormwater staff calculated the geometric mean(expressed in units of cfu/100 mL) for the 13 fixed interval sampling sites, based upon the most polluted stream segments for fecal coliforms. The top three polluted stream segments (during dry weather conditions) are Peters Creek Peters Creek at the Antique Dealership (9,751), Little Creek at Jonestown Road(998) and Salem Creek at Elledge Wastewater Treatment Plant(WWTP) (988). For FY 2023-2024, Stormwater staff collected fecal coliforms samples during and after storm events (wet weather conditions). The top three polluted sites for wet weather conditions during active rainfall conditions were Peters Creek at Antique Dealership (7,729), Brushy Fork at Reynolds Park Road(5,940), and Salem Creek at Elledge WWTP (5,727). Post-storm event results showed that the top three sites were the same as during the storm event with concentrations of 9,311, 1,273, and 1,146 cfu/100 mL, respectively. After evaluating concentrations for the past three permit years and during ambient weather conditions, Stormwater staff observed that the top ranked site for fecal coliform pollution is Peters Creek at Antique Dealership. As a preemptive measure, the Stormwater Division engaged HDR to stream-walk the segment from Hanes Park to the Antique 61 Dealership (1.75 miles) during dry weather conditions; HDR observed six potential sources of fecal coliforms, but no active discharges/releases were detected. For FY 2024-2025, Stormwater staff will conduct more intensive, investigative efforts as well as perform a more robust water sampling regime above/within the stream segment for more conclusive results. 6. Stormwater and Information Systems (I.S.) staff have successfully extracted potential septic tank locations from the city's utility bill system. As a result, Stormwater and I.S. staff created GIS layer of septic tank locations throughout the municipal boundaries. Stormwater staff consult the septic tank GIS layer, as needed, when performing IDDE investigations that contain elevated levels of fecal coliforms, ammonia, and nitrates for verifying the presence of a septic tank within the immediate vicinity. 7. City Council approved $300,000 for a new dewatering facility at City Yard, where street sweeping wash water and MS4 cleaning debris leachate will discharge into the sanitary sewer system. The new facility should begin construction activities approximately FY 2028-2029. 8. The Stormwater Operations Supervisor performed five inspections of industrial and municipal facilities within the Salem Creek, Peters Creek, and Brushy Fork Watersheds that have the potential to discharge fecal coliforms. 9. The Sanitation Department performed 18 sweeping events of municipally owned facilities/parking lots (Fleet Services, WSTA, Field Operations, and the Sanitation Garbage Truck) during FY 2023-2024. Stormwater staff estimates that approximately 234 acres (each sweeping event is approximately 13.0 acres) of impervious area was swept. 62 16.3 Muddy Creek Watershed TMDL In November 2011, the North Carolina Department of Environmental Quality (NCDEQ) issued a final report for turbidity impairment of the Muddy Creek Watershed. The Muddy Creek TMDL designates the City of Winston-Salem's MS4 as a significant contributor of turbidity (i.e. total suspended solids)pollution. A waste load allocation(WLA)was not assigned to the City's NPDES permit; however, total suspended solids loading (tons per a day)must be reduced by 58 percent. In accordance with its NPDES permit, the city must evaluate strategies and adapt BMPs to reduce TSS loading within the Muddy Creek Watershed. The Stormwater Division performed a BMP assessment and selected appropriate reduction strategies to mitigate TSS pollution. These selected BMPs are posted in the below table. 16.4 Muddy Creek Watershed TMDL BMP Summary Table Selected BMP Strategies Explanation of Desired Outcomes Inspection Regime for unpermitted/permitted Muddy Creek Watershed is experiencing an influx of construction Construction Sites—In order to ensure off-site activities due to land availability and improving economic sedimentation does not occur,Erosion Control staff conditions.

For FY 2024-2025, Stormwater staff will review HDR Engineering's stream-walking results of Muddy Creek and Silas Creek Watersheds to develop a prioritization plan for potential SCMs/BMPs to reduce identified TSS sources. 2. 6,051 linear feet of restored drainage ditches within the City of Winston-Salem to eliminate TSS sources. 3. The Sanitation Division swept 1,858 linear miles of street sweeping activities for public roadways within the City of Winston-Salem. 64 4. Stormwater staff calculated the arithmetic mean (expressed in units of milligrams per a liter) for the 13 fixed interval sampling sites and created a priority ranking,based on the most polluted stream segments. The top three polluted stream segments (during dry weather conditions) are Lower South Fork at Ebert Road(11.28 mg/L), Muddy Creek at Frye Bridge Road(10.47 mg/L), and Peters Creek at the Antique Dealership (10.41 mg/L). For FY 2023-2024, Stormwater staff collected total suspended solids samples during and after storm events (wet weather conditions). The top three polluted sites for wet weather conditions during active rainfall conditions were Fiddlers Creek at Thomasville Road(29.3 mg/L), Salem Creek at Fraternity Church Road(28.4 mg/L), and Salem Creek at Elledge Wastewater Treatment Plant(24.6 mg/L). Post-storm event results showed that the top three sites were Fiddlers Creek at Thomasville Road(17.6 mg/L), Peters Creek at Antique Dealership (11.9 mg/L), and Muddy Creek at Frye Bridge Road(7.2 mg/L). After evaluating TSS concentrations for the past three permit years and under dry weather conditions, Stormwater staff determined that the top ranked sites for TSS pollutants are Lower South Fork Creek at Ebert Road, Muddy Creek at Frye Bridge Road, and Peters Creek at the Antique Dealership and Salem Creek at Fraternity Church Road(both sites are ranked third). For wet weather conditions with only one year of data availability(FY 2023-2024), Fiddlers Creek at Thomasville Road is the most polluted stream due to TSS concentrations. Salem Creek from Elledge WWTP to the confluence of Muddy Creek, including the Fraternity Church site, is ranked second. Peters Creek at the Antique Dealership and Muddy Creek at Frye Bridge Road are tied for a third place ranking. For FY 2024-2024, Stormwater staff will focus investigative efforts upstream from the Lower South Fork at Ebert Road to determine potential TSS sources,based on available water quality data as well as stream-walking reconnaissance activities. 6. During water quality sampling activities, instantaneous results of ammonia, pH, and dissolved oxygen percent saturation, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate are collected. This information is located at\Water Sampling\Stormwater Sampling Databases\Current\Complete Stormwater Sampling Database_Current.xls Stormwater staff collected 546 results of instantaneous meter readings. 6. The Stormwater Division successfully resolved eight illicit discharges within the Muddy Creek Watershed. 7. The Sanitation Department performed 18 street sweeping events at Fleet Services, Sanitation's Garage Truck Storage Lot, Streets Operations Yard, and Winston-Salem Transit Authority. Stormwater staff estimates that approximately 234 acres (each sweeping event is approximately 13.0 acres) of impervious area was swept during FY 2023-2024. 65 APPENDIX A Appendix A Field Operations Department Stormwater Division Organizational Chart Ladonta Clark Vacant Stormwater Operations Stormwater Supervisor Robert Dockery Matt Osborne Stormwater Technician Stormwater Operations Analyst Nicholas Hole Andy Allen Stormwater Technician Assistant Stormwater Kent Wall Director Erosion Control/Floodplain Manager Vacant Senior Community Educator Isaac Howard i Erosion Control Inspector i Todd Love David Evans Sr.Civil Engineer Erosion Control Inspector Joe Fogarty Wesley Williams Keith Huff Stormwater Engineer Field Operations Director Erosion Control Inspector 2 Patrick Goode Ronnie Holbrook Civil Engineer Erosion Control Inspector Vicki Pigg Stormwater Operations Analyst 67 APPENDIX B Appendix B FY 2023-2024 Industrial & Municipal Goodhousekeeping Inspection List Permit Permit Facility Name Owner Type NPDES Permit Category Number Status Fleet Services Transportation with Vehicle MGH/D/ NCG080801 (Inspected twice during the PY Municipal Government Active Maintenance S/OI due to spill) NCS000247 Vegetative Management Municipal Government MGH Active MGH/D/S NCG060328 Dairy Farmers of America Non-Government Food and Kindred Active D/S NCGNE0000 Liquid Environmental Solutions Non-Government Stormwater Discharge,No Exposure Active D Certificate NCG160219 Yadkin Valley Paving INC Non-Government Asphalt Mixtures Active OI/D/S *=Legend Key D(Duration)=five years since last inspection OI(Outstanding Issues)=require a follow-up inspection MGH(Municipal Goodhousekeeping)=municipal operation/facility N(New)=never inspected by the Stormwater Division V(Verify)=verify permit status since last inspection S(Spill) 69 APPENDIX C APPENDIX C Stormwater/Erosion Control Division FY 2023-2024 Water Quality Monitoring &Assessment Program Fixed Interval, Instanteous Meter Results Rain Amount at DO Sample pH DO Saturation Temp.
