STORMWATER MANAGEMENT PROGRAM OVERVIEW MISSION STATEMENT The mission of Stormwater Management is to restore, protect, and preserve the surface waters within the City of Winston-Salem and to maintain, repair, map, and evaluate drainage systems within the street right- of-ways. PROGRAM DESCRIPTIONS Stormwater Monitoring and Administration: Manages the day-to-day operations of the Stormwater Management Program. Implements the requirements of the City’s Municipal Separate Storm Sewer System (MS4) permit. Performs watershed master planning by developing maps and inventories of the entire drainage system within the City. Monitors stormwater run-off as part of the program’s efforts to improve water quality. Provides educational programming to increase public awareness of water quality issues. Drainage Maintenance: Repairs, replaces, and upgrades the City’s drainage system within street right- of-ways. Provides for drainage system repairs on private property through the 70/30 program in which the City covers 70% of the cost for qualified projects. Removes debris from culverts and bridge abutments with many streams and creeks. Erosion Control: Provides for the enforcement of regulations pertaining to land-disturbing activity, watershed and floodplain requirements by reviewing development plans and issuing grading permits for all commercial and multi-family sites over 10,000 square feet in all areas of Forsyth County, excluding Kernersville. Monitors single family construction sites to ensure that sediment is controlled. Identifies tree save and potential critical areas, controls sedimentation, and limits the time of exposure on all applicable construction sites through plan review and field inspection. Maintains up-to-date floodway district maps to enforce floodway and floodway fringe regulations contained in the Unified Development Ordinance. Reviews survey and plan information and conducts field inspections to ensure that permitted structures comply with floodplain regulations. Enforces watershed regulations for density and impervious coverage on developed properties. Street Sweeping: Regenerative street sweepers are used year-around to remove litter, debris, and sediment from roads. Sweeping protects water quality by preventing materials from entering the storm drains. All debris swept is disposed of in the sanitary landfill.

Situated in Forsyth County, Winston-Salem is the fifth largest city in North Carolina and has an estimated population of 247,945 citizens (based on data from the U.S. Census Bureau). 2.2 Growth Rate: The City of Winston-Salem increased its population size by 8.00 percent from April 1, 2010 to July 1, 2019, while the State of North Carolina grew at the rate of 10.0 percent during the same period. 2.3 Jurisdictional and MS4 Service Areas: The City of Winston-Salem does not have any ETJ areas at this time. The square mile area for the City is 133.70. 2.3a Latitude of Center of MS4 Area: 36 degrees 06’ 9.95” N Longitude of Center of MS4 Area: 80 degrees 15’ 37.77” W 2.3b Storm Sewer Service Area (square miles): 133.70 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 eight 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), identify existing and future areas of flooding based on existing and future development patterns, and assess 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. 2.4a MS4 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. 8 2.5 Land Use Composition Estimates: The land use estimates below are from the City of Winston-Salem Planning Department (source: The Legacy, 2030) 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 N.C. Division of Water Quality (NCDWQ) 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. The NCDWQ determined that the Salem Creek Watershed is biologically-impaired due to excessive fecal coliform concentrations. As a result, the Stormwater Division continues to perform wet weather water sampling to determine pollutant origin sources of fecal coliform loading into Salem Creek. The City of Winston-Salem submitted a TMDL Implementation Plan to NCDWQ, which encompasses 22 sampling sites throughout Salem, Peters, and Brushy Fork Watersheds. Based upon historical analytical data results, monitoring locations are classified as contributing ‘hot spots’; pollutant loads are modeled by staff for designated storm events with upstream tributaries denoted for future sampling efforts. 9 3.

EXISTING WATER QUALITY PROGRAMS Local Programs Water Supply Watershed Protection – The Salem Lake Watershed Protection Article 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 in order to control alteration of natural drainage patterns, control development and to ensure stream velocities are not significantly increased. Erosion and Sediment Control – The City has established a program as authorized by the North Carolina Sedimentation Pollution Control Act of 1973. The Erosion Control Ordinance regulates certain land disturbing activities to control accelerated erosion and sedimentation in order 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 rodent control in the storm drainage system, sanitary sewers (manholes), and along creek beds. Other programs that support water quality within the City of Winston-Salem: 1.

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). 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 target pollutants of concern. Fecal coliform and turbidity pollution degrades 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, first flush, descending portion of a hydrograph, etc.), an accurate assessment of target pollutants has been established. Since 2011, 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 (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 16 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. It is also known that floatables and debris can carry and trap nutrients in our waterways. Floatables 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. Hispanic automobile repair shops, wrecked automobile 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, which is needed by aquatic fauna and flora to survive. 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. The Stormwater Division has identified numerous audiences for public outreach and education activities due to their potential risk of releasing targeted pollutants. Homeowners use lawn care products, dispose of household hazardous waste, and have pets and performance vehicular maintenance on their cars. Programs/workshops, such as Carolina Yards & Neighborhoods, address fertilizer and pesticide usage and pet waste. Other materials have been developed to address household hazardous waste, automotive maintenance, and volunteer opportunities. The Latino 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 in order to mitigate oil and grease releases. 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 measures, which curtail exposure of pollutants to rainwater. Stormwater staff focuses on educational efforts with commercial carwash facilities and businesses that wash vehicles and equipment; staff provides a non-residential carwash fact sheet in order to curb illicit activities. Erosion Control staff performs face-to-face informal meetings to discuss and implement corrective measures for containing sediment on-site. The Stormwater Division continues to work in collaborative efforts with the City/County Utilities Division in order to reduce sanitary sewer overflows and leaks. The Stormwater Division made an increased effort to boost awareness about floatables, debris, and litter in our local waterways. 8.3 Informational Web Site: The Stormwater Division operates and maintains an informative website in order to achieve a heightened awareness of stormwater-related issues and/or events. Information is updated every three months or upon a significant event or issue. The Communit y 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. 8.4 Distribute Public Education Materials to Identified User Groups: The City of Winston Salem distributes public educational materials that directly relates to specific, targeted audiences. In collaborated efforts with Stormwater SMART, the City creates communicative information for ranked pollutants of concern, such as fecal coliforms, oil and grease, sediment (i.e. total suspended 17 solids), nutrients and floatables. Educational materials (and opportunities) include brochures (paper and electronic), presentations, TV advertisements, workshops, community events, and targeted mailings. In order 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. 8.5 Promote and Maintain a 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. 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 Community Educator receives electronic notifications for presentation requests from CityLink or directly from website requests. Illicit discharges are received through the Stormwater Pollution Hotline (336-747-7480), which is operated by CityLink. The Stormwater/Sediment and Erosion Control Division has publicized its contact information 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. 8.6 Public Education and Outreach Program Summary 1. The City of Winston-Salem participated in the Stormwater SMART program through the Piedmont Triad Regional Council, a cooperative partnership of 27 local governments within the Piedmont Triad and overseen by a Steering Committee made up of representatives from each county or municipality. Stormwater SMART ran a digital media campaign targeting litter and household hazardous waste during the fall and spring of FY 2019-2020. The digital media included both English and Spanish materials. The advertisements were played on local TV and cable networks, including WFMY-TV News 2, WXII News 12, WGHP Morning News and Spectrum Prime Rotation 8pm-11pm. The video “Dispose of Properly” targeting household hazardous waste aired 125 times between September 9, 2019 and September 22, 2019. The video “Pick up Litter!” aired 131 times between March 30, 2020 and April 12, 2020. The two videos received an estimated 2,429,320 impressions on TV/Cable across the region and an estimated 655,528 impressions in Winston-Salem. Public service announcements (PSA) for household hazardous waste and litter also played on local radio stations. The radio PSA for household hazardous waste “Dispose of Properly” aired 143 times from September 9, 2019 top October 13, 2019 on the following stations WQMG-FM Urban Contemporary Adults 18-34+ Afr Amer (22 spots), WSMW-FM Adult Contemporary (87 spots) and WPAW 93.1 FM – Country Adults 18-44 General Market (23 spots). The radio PSA for litter “Pick up Litter” aired 154 times from March 30, 2020 to April 13, 2020 on the following stations: WJMH 102.1 Urban Cont.

Volunteer groups are given door hangers that contain stormwater education material informing citizens about fertilizer use, pet waste, and illegal dumping. These materials are placed in targeted areas where complaints have occurred. 9.3 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. The City Council has established committee level meetings that citizens are invited to attend to discuss any topic including stormwater management issues. The City Council committee that hears citizen input on stormwater management issues is the Public Works Committee. 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 make a suggestion 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. 9.4 Establish Hotline/Helpline: The City of Winston Salem has an established stormwater hotline that is attended by City Link staff 24 hours a day and 7 days a week. City Link staff can contact stormwater staff anytime if the need arises. 9.5 Public Review and Comment: Copies of the City Stormwater Management Plan are available for comment on the City’s website located at www.stormwatersmart.com. 21 9.6 Public Notice: The City of Winston-Salem will comply with applicable public notice requirements when implementing a public involvement and participation program. Compliance with 40 CFR 122.34 is achieved by working with the City Secretary’s Office, Marketing and Communications, and Community Assistance Specialists for scheduling, advertising, and posting public meetings. 9.7 Public Involvement and Participation Program Summary 1. Overall, public involvement opportunities in Winston-Salem’s Stormwater have remained stable and strong, in response to growing awareness of stormwater issues. 2. The Adopt-A-Stream program has groups that include scout troops, homeowner associations, church groups, and local businesses. In the past year, six groups participated in the adopt-a- stream program. 107 volunteers participated in eight stream clean-ups collecting 6,095 pounds of trash and recyclables. 3. Through Forsyth Creek Week, three clean-ups within Winston-Salem were conducted. The Stormwater Division organized a clean-up at Blum Park. The Blum Park Wetland was cleaned of all accumulated trash and debris - this park wetland is located within the Peters Creek Watershed. 25 participants collected 50 bags of trash and debris from the wetland in Blum Park. The second event included the Yadkin Riverkeeper organizing a clean-up of the Civitan Park Wetland and Salem Creek near Winston-Salem State University. 78 participants collected 100 bags of trash and bulky items from Civitan Park and Salem Creek. The third event entailed the Forsyth Off-Road Bicycle Association organizing a clean-up of Hobby Park in Winston-Salem. 21 participants collected ten bags of trash and recyclables and three tires. 4. One group completed a one-time clean-up of Peters Creek and Gateway Commons Park. 15 participants collected 25 bags of trash and approximately 20 bulky items including a sofa, a love seat, four lawn chairs, several folding chairs, cushions, a tent, outdoor gear, a propane tank, and a grill. 5. In cooperation with Forsyth Cooperative Extension and Forsyth Creek, 62 residents and professionals attended a workshop on rain water harvesting and rain gardens. 6. The Stormwater Division continued its storm drain marker program during FY 2019 – 2020 - two volunteers placed 32 markers and distributed 55 door hangers. 7. The Stormwater program conducted four Creek Crawls during the 2019-2020 school year and one Creek Crawl during the 2020 Forsyth Creek Week. 8. Business representatives and citizen groups, who attend monthly Public Works Committee Meetings, participate in the decision-making process concerning stormwater management within the City of Winston-Salem. The Public Works Committee invites citizens to participate in these discussions and agendas, which are posted on the City’s website. In addition, the City Council has created the Stormwater Appeals Board. The Stormwater Appeals Board hears and makes decisions of appeal of various ordinance including illicit discharge and post-construction stormwater controls. 9. Five professional development workshops were held during the 2020 Forsyth Creek Week. The workshops included a workshop for teachers and educators titled “Stream Ecology for Teachers”, a workshop for homeowners and landscaping professionals titled “Rain Harvesting Lunch & Learn”, two workshops for engineers, environmental and landscaping professionals titled “River Course 401: Construction Practices for Stream Restoration”, and a community workshop about the Blum Park Wetland project titled “Community Workshop: How the Blum Park Make-Over Solved Local Flooding”. 156 people attended these five workshops. 10. The Stormwater Division published its Stormwater Management Plan on its webpage; the public is greatly encouraged to provide feedback to Stormwater staff. 22 10. ILLICIT DISCHARGE and ELIMINATION Objectives: 1. Detect and eliminate illicit discharges, including preventable spills and illegal dumping into the municipal separate storm sewer system (MS4). 2. Implement appropriate enforcement procedures and actions. 3. Maintain a map showing the permittee’s major MS4 outfalls to state waters receiving discharges. 4.

The stormwater staff is adequate to provide enforcement actions, as per the existing ordinance. The adopted ordinance has an enforcement section that provides for notice of violations and civil penalties. One can reference the City’s Stormwater Illicit Discharges and Connection Ordinance, Chapter 75, at ARTICLE I. ILLICIT STORMWATER DISCHARGES AND CONNECTIONS 10.3 Maintain a Storm Sewer System Base Map: Inventories of the initial fifteen watersheds have been completed. A consultant is in the process of revising all watershed master plans as well as stormwater system inventories for the annexed areas of the City of Winston-Salem. The inventory is accessible as a GIS layer and amended from submitted new development as-built plans and ‘in-the-field’ surveyed locations. For FY 2020-2021, Middle and Lower Mill Creek Watersheds will be assessed for major outfall and MS4 inventory updates. 10.4 Inspect/Detect Dry Weather Flows at MS4 Outfalls in Targeted Areas: Illicit discharge detection and elimination procedures are contained within the Stormwater Division’s Sampling Manual, which is located on the filing cabinets in Room 53 (storage area on the ground floor). The Center of Watershed Protection and Mr. Robert Pitt published a guidance manual for program development and technical information regarding illicit discharge detection and elimination (IDDE). When compared to the IDDE manual created by the Center of Watershed Protection, the Stormwater Division’s standards of operating procedures were very similar. Instead of expending City resources to create its own manual, the Stormwater Division adopted Chapters 11, 12, and 13 from the Center of Watershed Protection’s IDDE technical manual. 10.5 Employee Training: Create and distribute a web-based power point presentation and booklet to all current and new municipal employees that are not administrative positions. 10.6 Establish a Public-Reporting Mechanism: Citizens may call the stormwater hotline or use the CRM system to report illicit discharges, connections, and disposal within the City’s limits. All pertinent information regarding reporting procedures is posted on the City of Winston-Salem’s website, www.cityofws.org and the Stormwater Division’s homepage, www.stormwatersmart.com. The public can call (336)727-8000 to report illicit discharges, spills, or connections for Stormwater staff to perform investigative activities. 10.7 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 registered or certified mail. 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 that the illicit activity has been resolved. Staff records electronic and hardcopies of all correspondence, photos, mapping, civil penalty assessments, and sampling results pertaining to the IDDE activity for future reference. 24 10.8 Illicit Discharge Detection and Elimination Program Summary Information 1. Mapping updates to the storm drainage system continue from initial efforts conducted in the prior permit years. A contracted consultant will be updating (including major stormwater discharge outfalls) the Middle and Lower Mill Creek Watershed masterplans. Basin tracing models have been incorporated into the geodatabase to allow staff the ability to track illicit discharges to their sources. Outfalls are being identified and field-screened as part of this process. 2. Staff has responded to 31 illicit discharge situations and issued eight Notice of Violations. 3. No civil penalties were issued this year because all violators achieved compliance. 4. As part of the MS4 inventory update, no dry weather flows were detected as potential sources of pollutants due to not having the watershed masterplan contract executed by City Council as well as COVID-19. 5. As part of the city’s Good Housekeeping and Pollution prevention programs, 339 new City employees were trained to identify and report illicit discharges. Additionally, two CityLink employees were trained by Stormwater staff during new employee training. 6. CityLink takes illicit discharge related calls 24 hours a day and submits them to staff for investigation. 7. Stormwater staff performs quarterly, fixed interval sampling at 13 locations throughout Winston- Salem for the following perimeters: BOD, TSS, TDS, Turbidity, Cd, Cr, Ni, Pb, Total & Dissolved Cu, Total & Dissolved Zn Total & Dissolved P, NO2, NO3, TKN, and fecal coliform that resulted in 468 certified lab results. There were 216 samples collected within the Salem, Brushy, and Peters Creek Watersheds. 8. Staff was unable to walk local streams in order to evaluate for illicit discharges/connections due to limited staff availability and the COVID-19 pandemic. 9. All illicit discharge investigations were successfully resolved and permanently removed from the MS4. 10. The Stormwater Division reviewed and updated its Illicit Discharge Detection and Elimination Handbook for regulatory and compliance purposes in June of 2016. 11. Stormwater staff detected one sanitary sewer overflow that released to local waterways; these overflows were reported to Utilities Construction and Maintenance Section for permanent resolution. 25 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 that 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 NCDENR 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. Permits are required for any land disturbing activity that is equal to or greater than 20,000 square feet in surface area for development of a single-family dwelling, or 10,000 square feet on any land disturbing activity for any other purpose. For single- family residential sites under 20,000 square feet, an executed erosion control affidavit requires minimum measures to be implemented to prevent off-site sedimentation. 11.1 BMP Summary Table BMP Measurable Goals YR 1 YR 2 YR 3 YR 4 YR 5 RESPONSIBLE POSITION / PARTY a Erosion and Sediment Control Program Local program mandates NCDENR approved sediment & erosion control practices for construction activities disturbing more than 20,000 ft2 for single-family construction or 10,000 ft2 for any other purpose, plus a single-family residential program.

X X X X X NC Division of Land Resources CityLink Marketing & Communications Section Best Management Practices for Construction Site Runoff Controls: 11.2 Erosion and Sediment Control Program: The Sediment and Erosion Control Section of the City of Winston-Salem’s Stormwater/Erosion and Sedimentation Control Program require erosion and sediment control measures at construction sites. Article V of the Unified Development Ordinance (Chapter C) 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: Article V Erosion Control. 11.3 Develop Requirements for Construction Site Operators: Article V of the Unified Development Code, Section 5-7(G) and 5-16.1 states that no person shall undertake any land disturbing activity without first obtaining a permit from the Directors. Section 5-16.2 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 purpose must be permitted. To be permitted, Section 5-18.7 mandates the creation and submittal of a development plan and Section 5.8 provides the design standards criteria of erosion and sedimentation control measures, structures, and devices to be reviewed, approved, and installed. 27 Three City Divisions monitor and eliminate construction site wastes from adverse impacts to water quality. The Building Inspections Section requires construction solid waste (for example wood, sheet rock, concrete truck washout, etc.) to be placed in trash receptacles and disposed at an appropriate facility. Off-site sediment recovery and maintenance of erosion control structures are regulated and enforced by the Erosion Control Section. Any other pollutants that are directly (or indirectly) discharged, disposed, or illicitly-connected to storm drain systems (public or private-owned) or to Watercourses and Waters of the State, which are located within city limits, are monitored and enforced by the Stormwater Division. 11.4 Educational and Training Materials for Construction Site Operators: Erosion Control Inspectors perform on-site and in-office educational discussions with licensed contractors, designers, and developers, as per service requests and/or issuance of violations. These educational discussions are very interactive and personal. In addition, inspectors have distributed approximately 1,000 educational pamphlets to construction site operators for FY 2019 - 2020. 11.5 Plan Reviews: 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. As a result, sediment control devices for construction activities are evaluated for capture of 75 percent of the 40 micron particle and larger. 11.6 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 and Sediment Control Section has been integrated into the CityLink system and implemented a 72 hour response time of first knowledge. The Sediment and 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. In addition, by calling 1-866-STOPMUD, citizens can report violations of the Sedimentation Pollution Control Act. The Sediment and Erosion Control Section responds to e-mails and received complaints from the hotline within 48 hours of first knowledge. 11.7 Inspection and Enforcement Procedures: Site inspections are conducted by one of four qualified erosion control inspectors, which are assigned to a section of Forsyth County. Each inspector reviews, approves and releases grading/erosion control permits for construction activities, conducts on-site inspections, and ensures program compliance in their respective part of the County. Routine inspections are performed once every four weeks, however, the frequency of inspections will increase (as needed) for overall program compliance. 28 Enforcement action provisions are described in Sections 5-18.8, 5-20, 5-21, 5-22, 5-23, and 5-25 of Article V of the Unified Development Ordinance (Chapter C). The City of Winston-Salem 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) from an erosion control inspector with violations of noncompliance and a compliance due date will be listed. Mitigation activities are enforced in the event of off-site sedimentation - NCDWR receives a copy of every NOV that is issued by the Erosion Control Section. If the corrective measures are not resolved by the due date, a monetary fine, Stop Work Order, and/or Injunction may be imposed on the developer or contractor. In addition, the City of Winston- Salem may withhold any certificates of occupancy until absolute resolution has been achieved. 11.8 Eminent Domain Authority: The City of Winston-Salem’s Sediment and Erosion Control Section has an established procedure of sending a copy of every issued grading permit and application within Forsyth County to the Winston-Salem Regional Office of NCDENR. This protocol provides DEMLR the opportunity to collaborate with the Stormwater/Erosion Control Division concerning the approval of a post-construction stormwater management BMP within the City’s limits. 11.9 Construction Site Runoff Control Program Summary Information 1. In the past permit year, the Sedimentation and Erosion Control Program has reviewed 97 plans and conducted over 3,900 construction site inspections. Those inspections have resulted in 43 Notices of Violation and one civil penalty to bring about compliance. 2. The Erosion Control Section achieved a 79% average of compliant sites versus the total number of active construction sites. 29 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 SCM Summary Table SCM Measureable Goals YR 1 YR 2 YR 3 YR 4 YR 5 RESPONSIBLE POSITION/PARTY a Post-construction Stormwater Management Program The City of Winston Salem adopted a Post-construction Stormwater Control Ordinance in September of 2008. x x x x x Field Operations Director b Strategies which include SCM’s appropriate for the MS4 The City uses the State SCM Manual as engineering criteria for stormwater plan submittals. x x x x x Field Operations Director c Deed Restrictions and Protective Covenants Deed restrictions and protective covenants are required in the City’s ordinance to ensure that stormwater controls are not altered or removed. x x x x x Field Operations Director Stormwater Engineer d Operation and Maintenance Plan An operation and maintenance plan is required as part of the permit approval process.

The City of Winston-Salem has supplemented previous water supply watershed regulations with current post-construction regulations for Class ‘C’ waters in order to address stormwater runoff from new and re-developed sites. The City of Winston-Salem has adopted the State’s Best Management Practices Manual as a technical guide for designing structural SCMs within its municipal boundaries. 30 12.3 Strategies that include SCMs 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. Structural and non- structural SCMs will be utilized to address the requirements of 15A NCAC .0126 10(e). These SCM’s 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. Fecal Coliform Source Control: The City of Winston-Salem coordinates with the Forsyth County Department of Public Health to reduce fecal coliform inputs to the MS4 to the maximum extent practicable. This process includes an oversight program to ensure proper operation and maintenance of on-site wastewater treatment systems. The City will also work to implement structural SCMs that encourage the die-off of fecal coliform bacteria to the maximum extent practicable. The City County Utilities Commission (CCUC) has an extensive capital improvement program to rehabilitate failing sections of the sewer collection system. Stormwater staff work closely with the CCUC to locate and resolve sanitary sewer overflows into the MS4. Non-Structural SCMs: 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 DWQ. The Unified Development Ordinance regulates development in the Water Supply watershed areas of the City. 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 SCMs: In 2008, the City of Winston-Salem adopted the State’s model ordinance, which provides sizing and performance criteria for water quality SCM’s. This 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 and/or less than two dwelling units per acre) must meet all NCDEQ Stormwater Design Manual low density Minimum Design Criteria (MDC). High density developments (greater than 24 percent built upon area and/or more than two dwelling units per acre) in addition to meeting all of the low density non-structural SCM requirements must also provide structural SCMs. In addition, City Council adopted water quantity standards for stormwater SCM design in order to mitigate detrimental downstream effects of flooding and erosion in various design storm events. Any SCM or combination of SCMs designated as primary SCM’s in the NCDEQ Stormwater Design Manual, which are suitable to be effectively constructed in the Piedmont physiographic region, may be approved by the Stormwater Engineer. 31 12.4 Deed Restrictions and Protective Covenants: The City of Winston-Salem created, adopted, and implemented its post-construction ordinance on September 19, 2008. This ordinance includes comprehensive regulatory procedures in order 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. 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: ARTICLE IV. POST CONSTRUCTION STORMWATER 12.5 Operation and Maintenance Plan: Stormwater Division personnel inspect water quantity SCMs as well as Salem Lake Watershed (Water Supply IV Classification) stormwater management controls on an annual basis. Stormwater control devices, which were approved after the adoption of the post-construction ordinance, must have an Operation and Maintenance Agreement recorded as part of the ordinance permit process. The emphasis of SCM inspection and maintenance is placed on the designated property owner. Beginning after the certification of the as-built drawings for a permitted stormwater management system, the 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 Traffic Field Operations Director for review on an annual basis. The Field Operations Director or his designee may carry out his own inspection to validate such submitted records. The City of Winston-Salem inspects all City-wide water quantity SCMs that were approved prior to the Post-construction Stormwater Control Ordinance implementation as well as water quality SCMs contained within the Salem Lake Watershed on an annual basis. The City requires performance bonding or other cash securities on SCMs within the water supply watershed areas. Currently, all structural SCMs approved in accordance with the post-construction ordinance must have a financial surety in force prior to permit issuance. 12.6 Educational Materials and Training for Developers: Multiple training sessions have been provided by Stormwater Division staff prior to and after the ordinance implementation in 2008. Educational materials include a post-construction stormwater permit application, a guidance 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 also makes himself regularly available to meet with developers at their request on both an individual basis and via interdepartmental design review committees, in the event that they need guidance on permit policies and procedures before submitting an application for a permit. The Stormwater Engineer has on average four to five such meetings on a weekly basis. 12.7 Post-construction Stormwater Control Summary Program Information 1. In terms of SCM performance and maintenance securities for permits issued under the 2008 implemented ordinance, the Stormwater Division requires a developer/owner of a commercial development to post a financial surety prior to permit issuance. For commercial developments, this surety is in the form of a one-time cash payment equal to four percent of the total cost of the stormwater management system. The monies are 32 deposited into a City maintained catastrophic failure fund. The City will allocate funds to developers/owners who have contributed to the fund when deemed necessary for SCM maintenance repairs or reconstruction redevelopment in the event of a catastrophic failure. Residential developments require the developer to establish an escrow account into which the developer pays an amount equal to 15 percent of the construction cost of the stormwater management system. The home owners association must then fully fund the remainder of the account within ten years of as-built certification of the Stormwater management system. The HOA funding amount is based on an engineer’s estimate of annual maintenance costs and this estimate is provided at the time of permitting. The HOA must then fund two thirds of this estimate into the escrow account within five years of as built certification and as mentioned fully fund the account within ten years of as- built approval. 2. The Stormwater Division has inspected 265 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’ = 56 (21.13%) b. The number of SCMS that are categorized with minor issues = 46 (17.36%) c. The number of SCMS with no deficiencies = 163 (61.51%) 3. 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 = 49 b. Sand Filters = 49 c. Bio-Retention Cells = 24 d. Stormwater Constructed Wetlands = 1 e. Contech Stormfilter System = 5 f. Bay Filter System = 4 g. Infiltration Trench = 3 h. Permeable Pavement System = 4 i. Dry Detention Basins/Underground Management Systems = 62 In addition to these high density developments in the same period, the Stormwater Division has also issued 74 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. 33 4. During Permit Year of 2019 – 2020, the following information summarizes post- construction activities performed by the Stormwater Division: a. The number of plans reviewed = 50 b. The number of developments requiring water quality SCMs = 7 c. The number of developments requiring water quantity SCMs = 10 d. The number of no adverse impact studies submitted in lieu of management for quantity control = 2 e. The number of developments meeting the ordinance water quality provision exemptions = 30 f. The number of developments meeting the ordinance water quantity provision exemptions = 35 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 = 2 h. The number of low-density projects =11 i. The number of high-density projects = 7 j. Sum of water quality SCMs = 8 (1 Sand Filter, 3 Wet Detention Basins, 2 bay filters, 1 Contech Filter, 1 Permeable Pavement System) k. Sum of water quantity SCMs = 12 (3 Wet Detention Basins, 1 Sand Filter, 3 Underground Management Systems, and 5 Dry Detention Basins). 34 13.

Next, Stormwater staff prioritized these municipal operations for SPPP 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 in order to create and implement BMPs for mitigating or eliminating exposure of pollutants to stormwater runoff. The following tables provided an overview of the City’s progression in reducing stormwater pollution from municipal operations, as of June 2019. 36 Municipal Facilities/Operations that have Comprehensive Stormwater Pollution Prevention Plans (General Stormwater Permitted or Operations that require SPPPs, as if permitted) Table 13.3 City Department Division or Operational Activities Contact Name NPDES Permit Number Utilities Muddy Creek WWTP Courtney Driver NC0050342 Archie Elledge WWTP Courtney Driver NC0037834 Hanes Mill Landfill Jan McHargue NCG120034 Property Facilities Management Fleet Services Nick Geis NCG080801 WSDOT Winston-Salem Transit Authority Toneq’ McCullough NCG080023 Traffic Field Operations, City Yard Salt, Sand, and Soil Storage and Maintenance Activities Keith Huff N/A Sanitation Refuse & Yard Waste Collection, Household Recycling Chris Christmas N/A Fairgrounds Annex Concerts, Sporting Events, Ice-Skating Robert Mulhearn N/A Benton Convention Center Food Service, Convention Activities Ben Rowe N/A Dixie Classic Fairgrounds Food Service, Agricultural Exhibits, Automobile Demolition Derby Cheryle Hartley N/A Bowman Grey Stadium Automobile Racing, Sporting Events, Food Service Ben Rowe N/A Municipal Facilities/Operations that have Abbreviated Stormwater Pollution Prevention Plans (Spill Response Plans and Procedures, Site Maps, and Nonstructural BMPs) Table 13.4 City Department Division or Operational Activities Contact Name NPDES Permit Number WSDOT (Five facilities) Parking Decks/Lots Toneq’ McCullough N/A Recreation and Parks (30 facilities) Equipment Maintenance and Washing, Swimming Pool Chemicals, and Recreation Centers William Royston N/A Central Warehouse (Two facilities) Fertilizer and Chemical Storage Nick Geis N/A Fire (21 facilities ) Fire Stations and HazMat Storage Chief William Mayo N/A 37 Municipal Facilities/Operations that are scheduled for Site Assessments and/or Stormwater Pollution Prevention Plans (General Stormwater Permitted or Abbreviated – Depends on Operational Magnitude and Nature of Activities) Table 13.5 City Department Division or Operational Activities Contact Name NPDES Permit Number Utilities Construction and Maintenance Division Courtney Driver N/A Northwest WTP Courtney Driver NC0086762 Thomas WTP Courtney Driver NC0079821 Neilson WTP Courtney Driver NC0086011 Police Crime Evidence Storage and Vehicle Preparation and Processing Chief Catrina Thompson N/A Vegetation Management Chemical Storage and Fertilizer Application Activities Nick Geis N/A Neighborhood Services Abandoned Automobile Storage Area Marla Newman N/A Property Maintenance Properties that may cause or contribute to stormwater pollution Nick Geis N/A 3RC Household Hazardous Waste Disposal Michelle Sakwa N/A WSDOT Traffic Maintenance, Warehouse Storage, and Paint Shop Activities Keith Huff N/A Best Management Practices for Pollution Prevention and Good Housekeeping for Municipal Operations: 13.6 Operation and Maintenance Program for Municipal Facilities: The City of Winston-Salem has created and implemented multiple comprehensive programs in order to mitigate or eliminate pollutant exposure from entering the Waters of the State or MS4 – please reference the BMP Summary Table 13.3. 13.7 Site Pollution Prevention Plans for Municipal Facilities and Operations: The Stormwater Division has identified 25 municipal facilities/operations that have the significant potential for generating polluted stormwater runoff. As of June 2020, 15 municipal facilities/operations have implemented stormwater pollution prevention plans (SPPPs) in order to remove pollutant exposure to stormwater runoff (Tables 13.3 and 13.4). Ten municipal facilities/operations have been designated for site pollution assessments/inspections with SPPP creation and implementation, if needed (Table 13.5). 13.8 Inspection and Evaluation of Municipal Facilities and Operations (including the MS4 system and associated Structural BMPs): The Stormwater Division has been conducting good housekeeping inspections of municipal facilities/operations since January 2004. 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 38 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 Division/Department Superintendent and Director of Operations Johnnie Taylor. The Stormwater Division retains an electronic copy and hard copies of completed inspection forms. 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 October 2013; an update was finalized by staff in June 2020. 13.9 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 SPPP has been created and implemented by City staff. A key component of this abbreviated SWPPP is spill response plan and procedures that are site-specific. Each municipal operation/facility performs spill response training on an annual basis. Table 13.4 contains a list of municipal facilities/operations that have implemented an abbreviated SPPP. 13.10 Prevent or Minimize Contamination of Stormwater Runoff from all areas used for Vehicle and Equipment Cleaning: Upon inspection of each municipal facility/operation, structural and nonstructural BMPs are recommended for implementation. Stormwater staff promotes vehicle/equipment washing at City Yard. 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 structural BMPs cannot be installed, the vehicle-washing activities will be performed in accordance with NPDES requirements. Selected BMPs will be incorporated into an abbreviated SPPP in order to reflect on-site practices and measures. 13.11 Select BMPs for Pollutant Reduction on Municipal Streets, Roads, and Public Parking Lots: The Stormwater Division has worked in collaborative efforts with Winston-Salem Transit Authority, Streets Division, and Winston-Salem Department of Transportation in order to identify pollutant-laden stormwater runoff from public streets, roads, and parking lots. Selected BMPs for implementation include increased street sweeping, enhanced MS4 trash and sediment removal, issuance of condensed spill response plans and procedures for hydrocarbon releases, and implementing a maintenance program for existing structural BMPs, which receive inputs from public streets and roads. 13.12 Implementation of Maintenance Programs for Municipal Streets, Roads, and Public Parking Lots: The Stormwater Division has amended the contractor’s street sweeping agreement to allow additional sweeping activities to occur on an ‘as needed’ basis, if conditions require further cleaning. For example, these services have been used on several occasions when sediment has been deposited in a public street and no responsible party could be identified. 13.13 Operation and Maintenance (O & M) for Municipal Structural Stormwater BMPs and the Stormwater Sewer System: The Stormwater Division has developed and implemented a comprehensive operation and maintenance program for structural BMPs as well as the MS4. This O & M Program includes (but not limited to) these activities: 39  Street (right-of-way) structure maintenance (pipes and catch basins): drainage structures are inspected and cleaned, as needed. Structure condition is denoted and prioritized for repairing, when required.  Street sweeping: each city street is swept once a year with heavily polluted roadways being swept bimonthly. The Streets Division contracts with an outside vendor, who utilizes high efficiency vacuum street sweeper for maximum pollutant (e.g. trash, TSS, and nutrient) removal. 13.14 Conduct 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 goodhousekeeping 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. 13.15 Pollution Prevention and Good Housekeeping for Municipal Operations Prog ram Summary 1. Stormwater staff performed one Stormwater Pollution Prevention Plan (SPPP) inspections/reinspections at Fleet Services during FY 2019 - 2020. 2. As the City of Winston-Salem hired new employees, 339 city employees viewed the stormwater orientation video and received a copy of the handbook, Stormwater Runoff: Municipal Good Housekeeping and Pollution Prevention. Additionally, two CityLink employees were trained by Stormwater Staff during new employee training. 3. The City’s Recycle Today Program has collected 10,842.16 tons of recyclable materials during FY 2019 - 2020. Please refer to Appendix B for tabular quantities of recycled materials. 4. 3RC collected and recycled, reused, or incinerated 513 tons of household hazardous materials. 5.

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 has updated this master list in March 2020; annual evaluating and updating of the master list will be performed by the Stormwater Inspector. 41 14.3 Inspection Program: Initially, inspection techniques consisted of examining every permit compliance measure in accordance with state NPDES stormwater permit, inspect the inside facility for illicit connections, and focus on SPPP records. 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 written SPPP protocols 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 2. NC Department of Water Resources Database (General and Individual Permitted industrial facilities, as per 40 CFR 122.26) 3. The City of Winston-Salem Facilities’ Database (Municipal Operations/Facilities that are permitted under 40 CFR 122.26) 4. Illicit Discharge Reports 5. Prioritized pollutants of concern (e.g. TMDL watershed, recurrences in water quality exceedances of standards, etc.) 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 Industrial Inspector will target these facilities for inspections; our goal is to inspect every permitted facility once every five years. 14.4 Establish and Implement Measures to Evaluate Commercial and Industrial Facilities discharging stormwater to the City’s MS4: During the course of the on-site inspection, the Stormwater staff evaluates first flush data in regards to benchmark values from the NPDES permit, visual field observations 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. The Stormwater Division has a good working relationship with the NC Division of Mineral and Land Resources, Winston-Salem Regional Office. A copy of every completed inspection and reinspection form is forwarded to Mr. Brandon Wise, Environmental Specialist, who is assigned to Forsyth County. 14.5 Monitor and Evaluate Stormwater Discharges to Municipal Systems Program Su mmary 1. During FY 2019 - 2020, the Stormwater Division inspected/reinspected two industrial facilities - please refer to Appendix C for a complete list. 2.

Appendix D contains numerous maps of fixed interval monitoring locations throughout the City of Winston-Salem. Samples are collected in a composite method, except for fecal coliforms, which are grab samples 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. 15.3 Water Quality Assessment and Monitoring Program Summary: monitoring and assessment data is analyzed for trends over time in order to identify problem areas that are emerging or that need additional regulatory/non-regulatory actions to support management decisions such as TMDLs, NPDES permits, ordinance enforcement, and nonpoint sources. 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, NO2, NO3, TKN, and fecal coliforms. During FY 2019 – 2020, Stormwater staff collected 636 water samples with certified laboratory analyses and 216 water samples were collected within Salem, Brushy Fork, and Peters Creek Watersheds. Appendix E contains fixed interval water quality data for FY 2019 – 2020. 2. Stormwater Field staff collected and analyzed 984 instantaneous parameters for FY 2019-2020 via YSI multiparameter meters as well as portable Chemets test kits for ammonia and nitrate detection. 3. Stormwater staff collected 37 fecal coliform samples within Salem Creek, Brushy Fork, and Peters Creek Watersheds in order to observe bacterial loading concentrations within impaired, local waters. 43 16. TOTAL MAXIMUM DAILY LOADS (TMDLs) Objectives: 1. Determine whether a TMDL has been developed and approved or established by EPA for the receiving water(s) of the permittee’s MS4 NPDES stormwater discharge. 2. The permittee will utilize BMPs within the six minimum measures to address the permittee’s assigned NPDES regulated stormwater waste load allocation (WLA) identified in the approved TMDL to the maximum extent practical and to the extent authorized by law. 3. If subject to an approved TMDL with a NPDES 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 MS4’s 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 regulated waste load allocation assigned to the permittee to the maximum extent practical. 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. 16.1 Salem Creek Watershed TMDL BMP Summary Table BMP Measurable Goals YR 1 YR 2 YR 3 YR 4 YR 5 RESPONSIBLE POSITION/PARTY a Identify, Describe, and Map Watershed, Outfalls, and Streams The City of Winston-Salem has completed a comprehensive watershed masterplan update of Salem, Brushy Fork, and Peters Creek Watersheds in 2011.

In addition, the Stormwater Division received hydraulic and hydrological modeling data as well as pollutant loading data for future BMP implementation projects. A revised reassessment date for these watersheds is scheduled for in FY 2021 - 2022. 16.3 Existing Measures: The City of Winston-Salem is implementing various structural and nonstructural BMPs to achieve its waste load allocation (WLA) for fecal coliform reduction within the Salem Creek Watershed. During FY 2019 – 2020, the Stormwater Division continued to maintain these programmatic BMPs: Existing Measures Status Explanation to Reduce Pollutant of Concern Central District PTRP Wet Pond – captures first flush of runoff from the adjacent Piedmont Triad Research Park. In addition, 355 acres of ultra-urban drainage area discharges to the pond. Pond has a surface area of 2.98 acres and average depth of ten feet (in the lower pond). 100 percent complete Designed to remove 85 percent TSS removal from influent, since fecal coliforms adhere to TSS, a reduction in TSS should yield a fecal coliform reduction of 50 percent. These reductions pertain to the PTRP drainage area only. Utilities Construction & Maintenance Division *Pipe Bursting and Slipping Program *Lift Station Repair and Rehabilitation Program *Flood Reduction Projects – Inflow and Infiltration 100 percent complete; on-going operation 80 percent of the City’s sewer collection system uses gravity for transporting sewage to the POTW. As a result, significant portions of sewer truck lines are positioned adjacent to streams. Targeted rehabilitation projects will be prioritized based upon constitutes of SSOs, such as grease, roots, and infrastructure age. 45 Illicit Discharge Detection and Elimination Program (IDDE) - the Stormwater Division performs fixed interval sampling regime of 13 sites across the City – 6 sites are located in Salem, Brushy Fork, and Peters Creek Watersheds. 100 percent complete; on-going operation Five NOV’s were successfully completed with TMDL Watersheds By proactively finding sanitary sewer overflows (SSOs) and reducing the quantity of sewage, the amount of fecal coliform pollution is minimized. As a result, the regeneration of fecal coliform bacteria within the stream matrix is reduced, which facilitates the recovery of the biotic ecosystem at a more rapid rate. Stream Walking (IDDE Program Component) – Stormwater staff walks local streams within the Salem, Brushy Fork, and Peters Creek Watersheds. 100 percent complete; on-going operation By proactively finding and eliminating illicit sewer discharges and connections, staff reduces the quantity of sewage released to surface waters. As a result, the total amount of released fecal coliform pollution is reduced. Due to 100% turnover rate in Stormwater Field Operations as well as the COVID-19 pandemic, stream- walking activities were not completed for FY 2019 – 2020. Public Education – Scoop-the-Poop campaign. The public educator highlights the detriments of fecal coliform pollution within a riverine ecosystem as well as ‘factoids’ of feces (e.g. the amount of fecal coliform bacteria per a gram of fecal matter, the average weight of a dog’s bowel movement, etc.) 100 percent complete; on-going operation 1,262 pet waste informational handouts were distributed throughout six locations. By making pet owners aware of the detriment of fecal coliform pollution, the Stormwater Division wishes to facilitate a behavioral change in citizens. If citizens remove feces from the open environment, the exposure of fecal coliform bacteria to stormwater runoff has been eliminated. Pet Waste Stations - the Senior Community Educator has identified 48 pet waste collection stations within green spaces throughout Winston-Salem, including downtown, which were installed by the City’s Recreation and Parks Department. 35 of these 48 pet waste stations are located in the Salem, Brushy Fork, and Peters Creek Watersheds. 100 percent complete; continuous operation Stations provide ease of access for pet owners to discard fecal waste and remove from the open environment. To encourage participation, the City furnishes waste bags to the public, which are positioned on top of the waste reticle. By eliminating the exposure of fecal matter to the runoff, bacteria are not discharged into waterways. Pet Waste Ordinance – the City of Winston-Salem has a forcible ordinance that requires pet owners to pick up fecal matter within its municipal boundaries. 100 percent complete; continuous operation By requiring pet owners to pick up fecal matter from their pets, the exposure of stormwater runoff to fecal coliforms has been eliminated, thus reducing the fecal pollution load to receiving waters. Erosion and Sediment Control Ordinance - the City of Winston-Salem continues to enforce its Sediment and Erosion Control Ordinance, as per the 1973 Sedimentation Control Act. Erosion control devices must be installed and maintained for disturbed areas greater than 10,000 square feet in order to retain soils on-site. 100 percent complete; continuous operation 103 erosion control inspections were performed by staff within the Salem Creek Watershed during FY 2019 - 2020. Fecal coliforms are transported to receiving waters by soil particles. In addition, fecal coliform bacteria become resuspended once discharged into the water matrix. As a result, fecal coliform bacteria proliferate at an increased rate and degrade surface waters more rapidly. Thus, a decreased sediment load yields reduced fecal coliforms to receiving waters. 46 SUSTAIN Modeling Study – A consultant preformed an EPA SUSTAIN model for the Salem Creek Watershed. Eleven structural BMPs were identified for installation or retrofit. 100 percent complete Based upon screening criteria, the consultant determined that eleven sites could be retrofitted or installed for bioretention cells or stormwater wet ponds. The modeling results showed that these eleven sites might produce a 1.9 percent reduction of fecal coliform pollution. The associated costs would total $15,113,135. Ditch Repair and Stabilization Program – the Streets Division hires a private contractor to repair and stabilize ditches within the public right-of-way. 100 percent complete; continuous operation 169 linear feet of ditch line was repaired and/or stabilized within the Salem Creek Watershed. Traffic Field Operations, City Yard assesses and prioritizes earthen conveyance swales that serve as drainage for ribbed and paved roadways. A private contractor restores channel capacity to the ditch by removing trash, sediment, or excessive vegetation. If needed, the contractor reestablishes vegetative cover within the ditch line in order to eliminate sedimentation to receiving waters. 70/30 Cost Share Drainage Improvement Projects on Private Property – the City of Winston Salem participates in repairing private drainage conveyances, structures, or channels. The City pays 70 percent of total costs; the private party pays the remaining 30 percent. The City of Winston- Salem offers its citizens a cost share program for public assistance to mitigate drainage issues on private property. One of the project qualifying criteria is severe erosion of earthen conveyances or stream banks; erosion is a sediment-gain source to receiving waters. The Stormwater staff offers advice to residential property owners regarding stream stabilization techniques and practices to reduce erosion. Forty (40) private property drainage investigations were completed in FY 2019 -2020 within the Salem Creek Watershed or its tributaries. Fats, Oil, and Grease (FOG) Reduction Program – the City/County Utilities Division has adopted and implemented a FOG Reduction Program to remove excess cooking and petroleum oils and grease prior to entering the sewer collection system. Responsible parties must have their grease/oil separators pumped out by licensed haulers at scheduled frequencies. 100 percent complete; continuous operation Grease and oil are the second-leading cause of sewer overflows that reach surface waters within the City of Winston-Salem. By requiring grease/oil interceptors to be properly maintained, these passive devices can effectively retain grease from entering the sewer collective system. As a result, the quantity of released sewage (and fecal coliforms) is reduced to streams. 16.4 Assessment of Available Monitoring Data: The Stormwater Section collected fecal coliform samples from six major, baseline locations within Salem, Peters, and Brushy Fork Watersheds. Stormwater staff collected 37 in-stream samples during dry weather conditions; all grab samples were analyzed by a North Carolina-certified laboratory. Appendix F contains fecal coliform data for FY 2019 – 2020. When assessing historical fecal coliform sample concentrations, staff observed numerous trends from the database. These observations include:  During wet weather conditions, all fecal coliform samples were above 400 cfu/100 milliliters. A majority of this sample population exceeded 1,000 cfu/100 milliliters.  Dry weather sampling results showed an inconsistent pattern of fecal coliform exceedances. When staff sampled the same outfall at differed time intervals, fecal coliform concentrations oscillated above or below the water quality standard for Class C waters. 47  The Stormwater Division identified the positive correlation of an independent variable to fecal coliform concentrations. As ambient temperature increases, so does fecal coliform concentrations within local streams.  A very weak correlation exists between fecal coliform concentrations and upland land use with insufficient evidence for predicting or isolating fecal coliform sources.  Due to the above-mentioned observations, the Stormwater Division assumes that fecal coliform pollution exists universally throughout its municipal boundaries. 16.5 Monitoring Plan: The Stormwater Division performed a comprehensive program evaluation of its TMDL monitoring plan in order to become more efficient and effective. The Stormwater Division implemented numerous modifications to the existing plan in July 2019. These modifications included:  Obtained absolute fecal coliform concentrations (through aliquot dilution) in stream segments to establish an impairment priority ranking.  Sampled targeted subwatersheds during varying weather conditions.  Perform water quality sampling at strategically-selected locations within Salem, Brushy Fork, and Peters Creek Watersheds in order to identify fecal coliform sources and/or evaluate stormwater control measures for pollutant removal efficiencies.  A location within Salem Creek (Fraternity Church Road) was sampled at a quarterly frequency for establishing baseline, pollutant concentrations.  Instantaneous water quality indicators were obtained at each sampling event. These parameters include water temperature, total dissolved solids, conductivity, pH, dissolved oxygen (milligrams per a liter and percent saturation), and rainfall amount or time since last rainfall.  Collected water samples in various dry and wet weather conditions. 16.6 Additional Measures: The City of Winston-Salem anticipates the implementation of numerous nonstructural BMPs in order to expand current pollutant reduction strategies within the Salem Creek and Muddy Creek Watersheds. By expanding current BMP strategies to the maximum extent practical, the City hopes to benefit from synergic pollutant reductions within the targeted watershed. The following matrix presents expanded measures (with corresponding explanations) in order to reduce fecal coliform loadings within the Salem Creek Watershed: Additional Measures Explanation of Designed Measures to Achieve MS4’s NPDES WLA to the MEP Status of Designed Measure (FY 2019 – 2020) Responsible Staff for Implementation Perform Goodhousekeeping Awareness Education with local Animal Shelters By evaluating current business practices, the Stormwater Division wishes to provide local shelters with new or modified cleaning methods to prevent or eliminate fecal coliform exposure to the open environment. 1,262 pet waste educational pamphlets were distributed to six local animal shelters, dog trainers, community events, and veterinary clinics. Senior Community Educator 48 Perform a collaborated awareness program with the City’s Parks and Recreation for signage and pet waste collection stations at frequently used municipally-owned areas. In addition, a stormwater representative will perform on-site educational presentations with park users. The Stormwater Division wishes citizens to have a heightened awareness of the detrimental effects of bacterial pollution to receiving waters. Thus, the overarching goal of this measure is to highlight the importance of collecting pet waste and eliminating the exposure of fecal coliforms to runoff. The Senior Community Educator is working to identify all pet waste station locations within the city limits; the Educator is working in collaborative efforts with the Recreation and Parks Department in order to weigh pet waste that is being collected. The overarching goal is to quantify removed fecal coliforms and nutrients from reaching surface waters. Senior Community Educator Facilitate a private-public partnership for pet waste receptacle placement in common areas of high density residential housing. By having readily access to disposal bins, the Stormwater Division anticipates targeted residents to use waste stations rather than leaving fecal matter on the ground. The Stormwater Division is fostering relationships with local apartment complexes for installing pet waste receptacles. Pet waste informative cards were distributed at two apartment complexes for tenants’ educational purposes. Senior Community Educator Evaluate municipal operations and facilities for opportunities of fecal coliform reduction. The goal of this measure entails the modification of work practices to eliminate fecal coliform exposure to the environment. By eliminating fecal coliform exposure, the overall waste load allocation is reduced. The Stormwater Inspector verified nonstructural BMPs at the Carolina Classic Fair Cattle Barn during operational activities. Stormwater Inspector Carolina Classic Fair Staff Create and implement confirmation methodology for locating failing septic tank systems within the City of Winston-Salem Failing septic tanks contribute human fecal coliform loading to the MS4, if illicit discharges are allowed to persist. By refining the City’s IDDE protocols for failing septic tanks, the City will achieve greater success in obtaining its waste load allocation. 100 percent complete; continuous operation Stormwater Technicians Stormwater Operations Supervisor Create and implement a water quality sampling program for ‘at-risk’ areas of exfiltration from the City’s sewer collection system. After significant storm events, Stormwater staff will sample the downstream stream for sewage indicator pollutants in order to minimize the quantity of released sewage. The Utilities Division has modeled and identified areas of exfiltration within the sewer collection system. Since 80 percent of sewer collection system is adjacent to surface waters, the likelihood of a SSO remains great. Therefore, a proactive program of mitigating released sewage to waterways remains paramount. 100 percent complete; continuous operation Stormwater Technicians Utilities Construction & Maintenance Engineering Staff Stormwater Operations Supervisor 49 Explore new methodologies of locating and removing failing septic tank systems from discharging into receiving surface waters. By utilizing GIS tools in conjunction with innovative techniques, the Stormwater Division proactively locates potential ‘hot spots’ of septic tank failures. 100 percent complete - continuous operation. Forsyth County Department of Health Stormwater Technicians Perform water quality sampling of stormwater discharge outfalls from municipally-owned properties that have a great potential to contribute fecal coliform pollution to streams. The purpose of this sampling effort is to confirm the justification of designing and constructing structural control measures to treat stormwater runoff. By validating fecal coliform pollutant concentrations, the Stormwater Division is able to justify and prioritize capital improvement funds for structural control measure expenditures. The Stormwater Division can maximize the pollutant removal efficiency per dollars spent. An overall reduction to the City’s WLA is expected from implementing structural control measures. Stormwater Technicians performed stormwater discharge outfall monitoring at Washington Dog Park. Finalized data validates the need for installing structural stormwater controls for reducing fecal coliform loading to Salem Creek. Stormwater Technicians Stormwater Operations Supervisor Street sweeping activities in ‘hot spot’ areas within the Salem Creek Watershed that focuses on strategic timing and location. Fecal coliform bacteria are transported into receiving streams by adsorbing onto soil particles. By increasing the frequency of street sweeping in designated areas, the City will eliminate the transport mechanism, thus reducing the fecal coliform loading within the Salem Creek Watershed. Street sweeping efforts have increased, in response to citizen complaints and designated areas of concentrated construction activities. In particular, the street sweeping activities have been significantly intensified for the Downtown Business District of Winston- Salem. Sanitation Director Field Operations Director Continued rehabilitation of infrastructure collection systems (sanitary sewer and stormwater) for continuous and effective operation Aging infrastructure creates conditions that permit fecal coliform pollution to persist, which include hydraulic overloading, sedimentation due to structural failures, and riverine flooding. Rehabilitation improvement projects will reduce fecal coliform loading by eliminating failure causes. 100 percent complete; continuous operation Utilities Construction & Maintenance Division Field Operations, City Yard 50 16.7 Implementation Plan: The City of Winston-Salem plans to implement the following structural and nonstructural BMPs in order to reduce fecal coliform pollution within the Salem Creek Watershed, in accordance with permit requirements. Appendix G contains a five year capital improvement project (CIP) list of proposed structural BMPs; numerous of these listed projects support fecal coliform load reduction within the City of Winston-Salem. Structural/Nonstructural Control Measures Explanation of Desired Outcomes Status and Schedule Washington Dog Park – a bioretention cell will receive the first inch of stormwater runoff from the upland drainage area. Storm flows greater than the first inch will be diverted to Salem Creek. Vegetative Management and Streets Drainage Divisions will perform routine maintenance on the bioretention cell. The Washington Dog Park is located within 75 feet of Salem Creek’s top of bank. The park is the only and most heavily-used dog recreational area within Winston-Salem. A pet waste receptacle is positioned at the park’s only access point; the total elimination of fecal coliform bacteria from the open environment remains unachievable to obtain. Thus, the permanent installation of a bioretention cell will remove the residual fecal matter from stormwater runoff. The anticipated pollutant removal of fecal coliform bacteria should be approximately 80 percent. The Field Operations Director has allocated $500,000 in CIP funding to construct a bioretention cell as well as restore 318 feet of an unnamed tributary to Salem Creek. SCM and streambank restoration construction work commenced during FY 2018 – 2019; construction activities were finished during FY 2019 - 2020. Blum Park Wetland – a stormwater wetland, within the Upper Peters Creek Watershed, that was constructed and placed on-line during FY 2015 - 2016. This 1.3 acre wetland was designed to receive the first inch of rainfall from the upland drainage area; this wetland serves as a focal point for the surrounding neighborhood. The wetland receives stormwater runoff from a drainage area of 168 acres, which is very diverse in upland land usage. Land uses of the drainage basin include light industrial, commercial business, institutional, and high density residential. All of the previously- mentioned land uses have great potential to export nutrient, fecal coliform, thermal, and metal pollutants, thus validating the need for a structural stormwater control in this strategic location. Because of permit workload requirements as well as staffing factor demands, the Stormwater Section was not able to collect influent and effluent water samples for the Blum Park Wetland. Based upon budget and staff availability for FY 2020 – 2021, Stormwater staff should be able to evaluate SCM performance . Sanitation Collection Truck Storage Yard – the city’s Engineering Division Property is retrofitting an existing facility to serve as a new storage area for sanitation collection trucks. Stormwater runoff from the proposed storage area will be conveyed into an oil water separator, which discharges into the facility’s stormwater wet pond. This treatment train is designed to reduce fecal coliform pollution through solid separation, exposure to ultraviolet radiation, and natural predation from protozoan organisms within the wet pond. The Stormwater Division will defer collection of the influent and effluent sampling due to pending facility maintenance until FY 2021 – 2022. 51 TMDL Monitoring Plan – a program evaluation was performed by staff, which revealed several information gaps within the monitoring plan. In order to devise a clearer and effective strategic TMDL masterplan, the Stormwater Division will implement new sampling procedures to identify and quantify fecal coliform loadings from contributing drainage areas. By incorporating new procedures into its Monitoring Plan, the Stormwater Division will be able to prioritize drainage areas for stormwater management controls. In addition, Stormwater staff becomes able to determine the appropriate nonstructural/structural control measures for implementation. A pilot study may result in a statistical correlation of workload measures to actual waste load reduction. New sampling procedures have been finalized with Stormwater staff with training completed regarding program amendments. The new sampling procedures were implemented in July 2019. Salem Creek Structural Control Masterplan – a consultant performed an assessment of the Salem Creek Watershed in order to generate a prospective list of sites for structural control measure placement. Once identified, computer modeling was used to develop a priority ranking system for BMP type, size, and projected costs. The masterplan serves as a long-term strategic blueprint to achieving the MS4’s waste load allocation. By strategically placing structural control measures on sites with high pollutant loadings, the Stormwater Division is able to validate the cost-effectiveness and removal efficiency to the public, elected officials, and the City Manager’s Office. In addition, the Stormwater Division will develop a long-term capital improvement project performa spending plan for Council’s approval. This structural control measure masterplan was completed and delivered to the Stormwater Division in July of 2013. Due to fund availability and project prioritization order, the first designated bioretention cell for implementation is scheduled to be operational by the summer of 2021. Since 15 sites were selected for BMP retrofit/installation opportunities, the Stormwater Division projects BMP implementation to continue until 2040. 16.8 Incremental Success: The Stormwater Division utilizes various mechanisms to document, analyze, and report incremental successes to achieve WLA reduction. 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 adopted the below- posted departmental standards for validating actual pollutant reduction loading to the effectiveness of implemented control measures. These standards include:  Perform water quality sampling before and after control measures have been implemented at major stormwater discharge outfalls. This methodology allows staff to determine the casual relationship of measure(s) effectiveness to actual pollutant reduction. Since water quality samples will collected during varying weather conditions, the overall trend in percent reduction should become evident over a period of time. The Stormwater Division realizes that other variables may cause anomalies or ‘outliers’ within trending data, but overall long-term declining percentages should be able to validate implemented control measures.  Long-term data (five to ten years) will be needed to provide observable 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 correlate a percent reduction.  Fecal coliform concentrations are interval data – a common standard is used to derive colony-forming units (cfu) per 100 milliliters of sample. Therefore, every effort should be spent to use statistical correlation to refine appropriate BMPs for WLA reduction. 52  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. Stream segments, within impaired watersheds, will be sampled for fecal coliforms in order to create a contribution load-ranking order. Once structural BMPs have been successfully implemented, staff will sample both influent and effluent locations in order to obtain the reduced waste load percentage from receiving waters. A cumulative table (e.g. Excel spreadsheet) will track all removed pollutant loading within the Salem Creek (and contributing tributaries) Watershed. Staff will continue to collect fecal coliform samples at a baseline monitoring station, which is positioned within the bottom reach of the watershed. This baseline station will confirm the overall reduction of fecal coliforms concentrations within the watershed. By continued efforts of BMP implementation, the City of Winston-Salem strives to achieve its waste load allocation reduction. 16.9 Total Maximum Daily Loads (TMDL) Program Summary 1. 6,011 linear feet were stabilized in streams or dry ditches within the City of Winston-Salem. 2. A contracted vendor performed 20,082.64 linear miles of street sweeping activities for public roadways during FY 2019 -2020. 3.
