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.

STORM SEWER SYSTEM INFORMATION 2.1 Population Served: Winston-Salem is in the northwestern area of the Piedmont Region of North Carolina. Situated in Forsyth County, Winston-Salem is the fifth largest city in North Carolina and has an estimated population of 249,545 citizens (based on data from the U.S. Census Bureau, as of July 1, 2020). 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 currently. The square mile area for the City is 132.45. 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): 132.45 2.4 Municipal Separate Storm Sewer System (MS4): The City of Winston-Salem is authorized to discharge stormwater from its municipal separate storm sewer system (MS4) into the waters of the State of North Carolina. A National Pollutant Discharge Elimination System (NPDES) permit is the legal mechanism that allows the City of Winston-Salem to discharge stormwater runoff into streams. All six minimum measures, which govern the City of Winston-Salem’s Stormwater Program, are contained within this permit. The City of Winston-Salem is delineated into 17 different sub-watersheds that drain the City and its surrounding area. The streams, within these sub-watersheds, flow in a southwesterly direction into Lower Muddy Creek; the original fifteen watersheds had stormwater masterplans developed for staff by a consultant. Current objectives of masterplan efforts include providing a comprehensive update of the existing storm sewer inventory (contained within public, private, and industrial properties), 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, Table 4-1) Land Use Classification Residential 43.14 % Commercial 2.81 % Industrial 3.32 % Parks/Open Space 2.09 % Institutional 2.94 % Right-of-Way 8.15 % Office/Office Commercial 0.46 % Agricultural 15.71 % Vacant 20.97% Utility 0.41% TOTAL 100.0% 2.6 Estimate Methodology: Classifications are based on zoning districts with the corresponding acreage versus the total acreage of the City of Winston-Salem. For this assessment, schools have been calculated as institutional purposes and parks are listed separately (typically included in the residential classification). 2.7 TMDL Identification: The North Carolina Department of Environmental Quality (NCDEQ) has detected standard violations of turbidity and chlorophyll a at High Rock Lake, which is 25 miles south of Winston-Salem. A TMDL is currently being developed for wastewater point sources within the High Rock Lake Watershed, which indirectly receives stormwater discharges from the City’s MS4. The main contributing river to High Rock Lake is the Yadkin River, in which Muddy Creek discharges into near the Forsyth-Davidson County border. NCDEQ determined that the Salem Creek Watershed is biologically impaired due to excessive fecal coliform concentrations. As a result, the Stormwater Division continues to perform water sampling to determine pollutant origin sources of fecal coliform loading into Salem Creek. The City of Winston- Salem revised its TMDL Sampling Plan in 2019, which resulted in 22 water sampling sites being selected throughout Salem, Peters, and Brushy Fork Watersheds. Stormwater staff will perform basic statistical analyses of collected water quality samples; once a sufficient population of data points exists to discern an observable trend, staff will report its findings to NCDEQ. In November 2011, NCDEQ issued a final report for turbidity impairment of the Muddy Creek Watershed. The Muddy Creek TMDL designates the City of Winston-Salem’s MS4 as a significant contributor of turbidity (i.e. total suspended solids) pollution. A waste load allocation (WLA) was not assigned to the City’s NPDES permit; however, total suspended solids loading (ton per a day) must be reduced by 58 percent. In accordance with its NPDES permit, the city must evaluate strategies and adapt BMPs to reduce TSS loading within the Muddy Creek Watershed. 9 3.

EXISTING WATER QUALITY PROGRAMS Local Programs Water Supply Watershed Protection – The Salem Lake Watershed Protection Ordinance is in place to provide regulations, which protect drinking water quality in the Salem Lake Watershed. These regulations meet or exceed the minimum regulations established by the North Carolina Environmental Management Commission under the provisions of the Water Supply Watershed Protection Act of 1989. Floodway and Floodway Fringe Regulations – Winston-Salem has adopted floodway and floodway fringe regulations to control alteration of natural drainage patterns, control development and to ensure stream velocities are not significantly increased. Erosion and Sediment Control – The City of Winston-Salem and Forsyth County is a locally-delegated program that enforces the North Carolina Sedimentation Pollution Control Act of 1973. The Erosion Control Ordinance regulates certain land disturbing activities to control accelerated erosion and sedimentation to prevent the pollution of water and other damage to lakes and watercourses. NPDES MS4 Phase I Permit – The City was issued a new stormwater permit that became effective October 10, 2018. Program components include public education and outreach, public involvement and participation, illicit discharge detection and elimination, construction site runoff controls, post- construction site runoff controls, and pollution prevention and good housekeeping for municipal operations. Code Enforcement Section of the Neighborhood Services Division – Enforcement of the sanitation code relating to weeded lots, shrubbery, solid waste in yards and curbside trash. It also includes vector control in the storm drainage system, sanitary sewers (manholes), and along creek beds. 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). For the Muddy Creek TMDL, the pollutant of concern is turbidity (i.e. TSS). Most probable sources of turbidity (TSS) loading include construction sites, in-stream channel erosion, and industrial sites. Fecal coliform is the pollutant of concern from Salem Creek Watershed. Bacterial source tracking (BST) confirmed that sanitary sewer overflows, pet waste, and wildlife populations contribute to fecal coliform pollution. Once the High Rock Lake TMDL is approved, nutrients will be target pollutants of concern. Fecal coliform and turbidity pollution degrade biotic integrity, thus impairing the reproduction cycle of aquatic life within streams. The Stormwater Division performs quarterly, fixed interval sampling to determine pollutant exceedances (when compared to Water Quality Redbook Standards) within streams. Since samples are collected during various weather conditions (e.g. dry, 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 deposition on impervious surfaces, industrial facilities, and commercial car-washing 17 activities. Nutrient loading depletes available dissolved oxygen concentrations for aquatic life due to excessive algal blooms, thus affecting water resources. Scientific research has proven that litter and debris transport nutrients within our waterways. Litter and debris can also serve as surrogates for other pollutants due to being more visible and tangible to the public. Historical illicit discharge detection and elimination (IDDE) reports indicate that hydrocarbon oil and grease is the most frequently released pollutant of concern within the City of Winston- Salem. Automobile repair businesses, car salvage facilities, nonpoint oil spills/leaks on public streets, industrial entities, and commercial car-washing operations are sources of oil and grease pollution. Oil and grease float on the stream surface and obstruct sunlight, which is needed by aquatic fauna and flora. In addition, hydrocarbon oil and grease damage riverine habitat and sensitive spawning areas due soil adsorption. Since contaminated soil particles settle at the bottom of spawning beds, fish cannot reproduce and eventually, vanish from the stream. The Stormwater Division has identified numerous audiences for public outreach and education activities due to their potential risk of releasing targeted pollutants. Residents use lawn care products, dispose of household hazardous waste, own pets, and perform routine maintenance on their cars. Materials have been developed targeting residents to educate them about lawn care, household hazardous waste disposal, pet waste, and automotive maintenance. Programs or workshops, such as Carolina Yards & Neighborhoods, address fertilizer and pesticide usage and pet waste. Other materials have been developed to address automotive maintenance for businesses and stormwater volunteer opportunities. The Hispanic population is a growing segment within the city of Winston-Salem. General stormwater pollution information has been developed for this demographic as well as translations of current outreach materials in order to reach the Hispanic community in Winston-Salem. School-age children participate in Creek Crawls, an in-stream learning-experience concerning water quality issues and the difference between healthy and impaired streams. The overall goal from extensive school-age children education is to influence adult behavior, thus eliminating pollution-enhancing practices. A Stormwater Inspector performs industrial inspections and assessments on prioritized, permitted facilities; these inspections concentrate on pollution prevention and good housekeeping measures, which curtail exposure of pollutants to rainwater. Erosion Control staff performs face- to-face informal meetings to discuss and implement corrective measures for containing sediment on-site. Soon, the Stormwater Division will work in collaborative efforts with Winston- Salem/Forsyth County Utilities in order to reduce sanitary sewer overflows and leaks. 8.1(c) Informational Web Site: The Stormwater Division operates and maintains an informative website, https://www.cityofws.org/Stormwater, in order to achieve a heightened awareness of stormwater-related issues and/or events. Information is reviewed and updated as needed every three months or upon a significant event or issue. The Community Educator promotes the website at presentations, media releases, or posting the web address on distributed public educational materials. Topics for web postings range from pollutant ‘factoids’ to public involvement opportunities. The Stormwater and Erosion Control Divisions have publicized its contact information and the Stormwater Hotline/Helpline (CityLink) on the City of Winston- Salem’s main webpage. Once on the City’s homepage, a citizen can locate staff member’s name, e-mail address, and telephone number within four clicks of a computer mouse. The contact information for CityLink is located at the bottom of every city webpage and at the top of the Stormwater and Erosion Control Divisions’ webpages. 8.1(d) Distribute Public Education Materials to Identified User Groups: The city of Winston Salem distributes public educational materials that directly relates to specific, targeted audiences. 18 The City creates communicative information for ranked pollutants of concern, such as floatables, fecal coliforms, oil and grease, sediment (i.e. total suspended solids), and nutrients. Educational materials (and opportunities) include brochures (paper and electronic), presentations, TV advertisements, social media posts, workshops, community events, and targeted mailings. The city of Winston-Salem performs mass media outreach activities throughout the local area works in conjunction with the Piedmont Triad Regional Council (via Stormwater SMART). Stormwater SMART develops TV and radio public service announcements, social media posts, digital advertisements, and brochures (paper and electronic) to supplement the City’s own education and outreach efforts. To ensure the maximum educational effectiveness, the City correlates the informative technique to the targeted audience. For example, best management practices brochures are written in Spanish for Hispanic automobile repair shops. 8.1(e) Promote and Maintain a Stormwater Hotline/Helpline: In 2005, City Council commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem. Known to the public as CityLink, this communication center receives citizen-generated e-mails or telephone calls regarding stormwater-related items illicit within the City. The public can access CityLink from the city of Winston-Salem’s homepage of https://www.cityofws.org/; the CityLink button appears at the top portion of the City’s homepage and the CityLink contact information appears at the bottom of all City webpages. On the Stormwater Division’s homepage on the city website, the CityLink contact information is provided at the top of the page. The Senior 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. CityLink refers all illicit discharge complaints to Stormwater staff, who will investigate these reports within 24 hours. 8.1(f) Implement a Public Education and Outreach Program: The Senior Community Educator records the reach and extend of all educational outreach activities during the active permit year.

Events usually include Creek Crawls, photo contest, guided paddles and nature walks, lunch and learn presentations, a community read and book discussion, professional development workshops, homeowner and resident workshops, special children and teen’s programs at the public libraries, community clean-ups, water centered recreational activities, and other interactive programs. Creek Week occurs in March and organized by a committee of municipal, county, and non-profit organizations. • Creek Crawls are held with local school classes where the students visit a nearby creek to examine the water quality of the stream using water quality test kits and visual observations. Benthic macroinvertebrates are collected, examined, and discussed as to form an overall assessment of the water quality of the selected stream. Students are taught to collect water samples and to identify the macroinvertebrates collected based on provided keys as part of this ‘hands on’ approach. • The Stormwater Division co-coordinates the Adopt-A-Stream program with Keep Winston-Salem Beautiful to reduce litter, debris, and floatables in our waterways. Homeowner associations, companies, special interest groups, families, or other interested parties can request to Adopt-A-Stream in their area of interest. Interested parties will commit to conducting three clean-ups per year and the City will provide signage and debris removal after each cleanup. Keep Winston-Salem Beautiful also coordinates Adopt-A-Street and Adopt-A-Park programs to reduce litter, debris, and floatables in our community. • Big Sweep is conducted every year in October to remove trash and debris from local waterways. • The Great American Clean-Up in Winston-Salem is conducted every year in April to remove trash and debris from local streets, parks, and waterways. • The Stormwater Division coordinates the Storm Drain Marking program where volunteer groups place adhesive ‘No Dumping, Drains to Creek’ markers or use a provided storm drain marking stencil and spray paint on catch basins and other drainage structures within the community. Volunteer groups also distribute door hangers that contain stormwater education material informing citizens about fertilizer use, pet waste, and illegal dumping within targeted neighborhoods due to the number of reoccurring complaints. • The Stream Watch in Winston-Salem program encourages volunteers to visit local Winston-Salem waterways to make various visual observations about the habitat and water quality. Observations are shared through a GIS web app in cooperation with NC DEQ’s Stream Watch program. Volunteers are provided with Winston-Salem specific stormwater and stream educational information to help guide them through their visual observations. Volunteers are encouraged to report any illicit discharges they observe while participating in Stream Watch activities in Winston-Salem. 9.1(b) Establish a Mechanism for Public Involvement: The city of Winston-Salem has three main mechanisms for public input on stormwater issues and input on the stormwater management program: City Council Committee meetings, Stormwater Appeals Board, and the City Link “suggestion and comment” service. 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 23 that allows any citizen to suggest or comment, which relates to the Stormwater Management Program. These suggestions or comments are forwarded to the Department Head for review and action, if necessary. 9.1(c) Establish Hotline(s) or Helpline(s): In 2005, City Council commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem. 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 from the city of Winston-Salem’s homepage of https://www.cityofws.org/; the CityLink button appears at the top portion of the City’s homepage and the CityLink contact information appears at the bottom of all City webpages. On the Stormwater Division’s homepage on the city website, the CityLink contact information is provided at the top of the page. The Senior 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. CityLink refers all illicit discharge complaints to the appropriate Stormwater staff members, who will investigate these reports within 24 hours (except on the weekends). 9.1(d) Public Review and Comment: Copies of the City’s Stormwater Management Plan are available for public comment on its website located at https://www.cityofws.org/Stormwater. 9.1(e) Public Notice: The City of Winston-Salem will comply with applicable public notice requirements when implementing a public involvement and participation program.

X X X X X Stormwater Operations Supervisor Stormwater Technicians Stormwater Inspector Best Management Practices (BMPs) for Illicit Discharge Detection and Elimination: 10.1(a) Maintain Appropriate Legal Authorities: The City of Winston-Salem has an illicit discharge, connection, and disposal ordinance that regulates the introduction of illegal pollutants to the City’s MS4 and receiving streams. The ordinance was adopted by City Council in 2006. Stormwater staff possesses adequate regulatory authority to provide enforcement actions, which include enforcement mechanisms, such as issuance of notice of violations, levy civil penalties, and issue stop work orders. One can reference the City’s Stormwater Illicit Discharges and Connection Ordinance, Chapter 75, at ARTICLE I. ILLICIT STORMWATER DISCHARGES AND CONNECTIONS 10.1(b) Maintain a Storm Sewer System Base Map: The City of Winston-Salem has entered into a professional services contract with HDR Engineering for major outfall identification as well as creation of a comprehensive stormwater system inventory. For FY 2020-2021, Middle and Lower Mill Creek Subwatersheds will be surveyed and updated for a comprehensive stormwater inventory revision, which includes location of new major stormwater outfalls. 10.1(c) Inspect/Detect Dry Weather Flows at MS4 Outfalls in Targeted Areas: Illicit discharge detection and elimination procedures are contained within the Stormwater IDDE manual, which was last revised in November 2020. The Stormwater Division’s current standard operating procedures (SOPs) are based on the Center of Watershed Protection’s 2004 technical manual. Staff has modified these SOPs for functionality and cost-effectiveness, as new technology and funding become available, the Stormwater Division will update and adopt new practices, as needed. In FY 2021-2022, HDR will perform dry weather screening of new and existing major 27 outfalls as well as stream-walk selected stream segments in the Salem Creek Watershed (due to TMDL regulations). Once identified by HDR, Stormwater staff will track, identify, and eliminate all illicit discharges. If needed, Stormwater staff will collect water samples from outfalls and analyze for biochemical oxygen demand, ammonia, nitrate, pH, conductivity, fluoride, surfactants, and fecal coliforms. 10.1(d) Employee Training: The Senior Community Educator distributes a web-based power point presentation and booklet to all current and new municipal employees (pertinent field staff) in order to increase the success rate of detecting illicit discharges to the MS4/receiving waters. All new municipal employees, which are not in administrative positions, are required to review a web-based power point presentation and booklet regarding IDDE detection and reporting during orientation. Jason H. Bryant, Safety Inspector with the city’s Risk Management Department, dispenses IDDE booklets during safety audits. On an annual basis, the Senior Community Educator performs refresher training at a targeted municipal facility or operation. 10.1(e) Maintain a Public Reporting Mechanism: Stormwater staff will continue working with the IS department for maintaining the most current up-to-date information that can be accessed on our city website in order to keep the public informed. The reporting mechanism that the Stormwater Division uses is called CityLink. Once known of the reported issue, staff has 24 hours to respond accordingly to the reported situation. When CityLink receives an issue, the Assistant Director, Stormwater Operations Supervisor, and Stormwater Analyst receive an automated notification from CityLink. From there, management assigns staff accordingly to respond within the allotted period. 10.1(f) Documentation of IDDE Activities: When staff investigates an illicit discharge activity, a discharge report is developed and filed by the investigating staff member, regardless of the outcome. If an illicit activity is discovered, staff prepares a Notice of Violation (NOV), as per the requirements of Chapter 75-11 of the City Code. The NOV is sent to the violator(s) via certified mail or signature verified delivery by staff. The NOV clearly states the violation, as well as any abatement activities required by the City. Upon successful completion of abatement activities by the violator, a notification is sent stating that the illicit activity has been resolved. Staff records all electronic copies of all correspondence, photos, mapping, civil penalty assessments, and sampling results pertaining to the IDDE activity for future reference. Staff documents all IDDE incidents on an spreadsheet as well as a NOV/IDDE GIS layer for accurately tracking elimination activities. The city‘s Citizen Service Request (CSR) system is the main documentation source to bridge the communication gap between Stormwater staff and citizens. From there, citizens can call CityLink and receive information updates. 10.2 Illicit Discharge Detection and Elimination Annual Reporting Task Items for PY 2020 – 2021 1. HDR performed dry weather screening of major stormwater outfalls within Salem Creek, Brushy Fork Creek, and Peters Creek Watersheds, as a component of the city’s comprehensive MS4 inventory update. As of June 30, 2021, HDR Engineering staff has evaluated 677 major stormwater outfalls out of the estimated total 1,085 outfalls. Stormwater staff performed water quality testing of four major stormwater outfalls that had dry weather flows – no illicit discharges were detected. 2. Stormwater staff responded to 57 illicit discharges/cases, which resulted in 14 notices of violations (NOVs) being issued. 64 percent of issued NOVs were permanently and successfully 28 resolved within 30 days of initial violation issuance; 100 percent of NOVs were resolved within 60 days. 3. As part of the masterplan inventory update, HDR and Stormwater staff members investigated and screened four major stormwater outfall for the presence of pollutants. In addition, HDR staff stream-walked a total of 30 miles of waterways within Salem Creek Watershed, which is impaired due to fecal coliforms. 4. As part of the city’s Good Housekeeping and Pollution prevention programs, new city employees will continue to training in order to identify and report illicit discharges. During FY 2020-2021, a total of 301 new city employees were trained in IDDE detection and notification methods. 5. Stormwater staff continues to support the Senior Community Educator with public educational efforts regarding illicit discharge information. For FY 2020-2021, Stormwater Field Operations staff distributed 178 educational materials regarding illicit dumping to residences throughout Winston-Salem. 6. The Stormwater Division received 19 citizen response requests concerning illicit discharges through CityLink – all complaints were successfully resolved by the specified due date. 7.

Reduce pollutants in stormwater runoff from construction activities disturbing one or more acres of land surface and those activities less than one acre that are part of a larger common plan of development. 2. Provide procedures for public input, sanctions to ensure permit compliance, requirements for construction site operators to implement appropriate erosion and sediment control practices, review of site plans, which incorporates consideration of potential water quality impacts, and procedures for site inspection and enforcement of control measures. 3. A locally delegated program that meets or exceeds the state requirements covering the jurisdictional area of the permittee complies with the required minimum of this section. 4. The City of Winston-Salem has been delegated by NCDEQ-DEMLR to establish a local erosion and sedimentation control program to administer the Sedimentation Pollution Control Act of 1973; stormwater NPDES permit requirements will be fulfilled using this existing program. Grading permits are required for land disturbing activities that are greater than (or equal to) 20,000 square feet for new single-family dwelling construction (or part of a larger common plan of development) or greater than 10,000 (or equal to) square feet for any non-exempt purpose (or part of a larger common plan of development). For single-family dwelling sites under 20,000 square feet (and not in a larger common plan of development), an executed erosion control affidavit is mandated, which stipulates the installation of minimal erosion control measures to prevent off-site sedimentation. 11.1 BMP Summary Table BMP Measurable Goals PY 18-19 PY 19-20 PY 20-21 PY 21-22 PY 22-23 RESPONSIBLE POSITION / PARTY a Erosion and Sediment Control Program The local program mandates NCDEQ, DEMLR approved sediment & erosion control practices for construction activities disturbing more than 20,000 sq. ft. for single-family dwelling construction or 10,000 sq. ft. for any other non-exempt purpose.

Senior Community Educator Marketing & Communications Section 11.1(a) Erosion and Sediment Control Program: The Erosion Control Division of the City of Winston-Salem’s Field Operations Department require erosion and sediment control measures at construction sites. Chapter 8, Section 8.4 of the Unified Development Ordinance regulates land disturbing activities within Forsyth County’s boundaries (this includes the City of Winston-Salem). For additional information regarding the City’s Sediment and Erosion Control Ordinance, please visit this link: Chapter 8, Section 8.4. 11.1(b) Plan Review Process: Chapter 8, Section 8.4 of the Unified Development Code, Section 8.4.4 (A.) states that no person shall initiate any land disturbing activity upon a tract without having an erosion control plan approved by the Director or a designee and without having purchased the applicable permit through the Inspections Division office. Section 3.2.7 (A.) states that any area exceeding 20,000 square feet in surface area on one tract for construction of a single-family dwelling or 10,000 square feet on one tract for any other non-exempt purpose must be permitted. To be permitted, Section 8.4.4 (A.) mandates the creation and submittal of an erosion control plan, Section 8.4.17 provides the submittal standards and criteria of erosion, and sedimentation control plans to be reviewed, approved, and installed. When finalized, development plans are submitted to the City of Winston-Salem for permit approval of land disturbing activities; Erosion Control staff determines regulatory compliance in accordance with the Sedimentation Pollution Control Act of 1973 and Chapter 8, Section 8.4 of the City of Winston-Salem Unified Development Ordinance. As a result, sediment control devices for construction activities are evaluated for capture of 75 percent of the 40-micron particle and larger. 11.1(c) Field Inspections, Complaint Response, and Enforcement Procedures: Site inspections are conducted by one of three qualified Erosion Control Inspectors, which are assigned to a specific section of Forsyth County. One Erosion Control Inspector is solely dedicated to inspecting single family dwelling erosion control compliance. Inspector responsibilities include plan review and approval, issuance of grading/erosion control permits for construction activities, conducting on-site inspections, and performing enforcement actions, when needed. Routine site inspections are performed approximately once every three weeks; however, the frequency of inspections will increase (as needed) for overall programmatic compliance. Enforcement action provisions are described in Chapter 8, Section 8.4.20 of the City’s Unified Development Ordinance (Chapter 8). The Erosion Control Division will not issue a grading permit for a development site unless the sediment and erosion control plan has been approved. Deviation from the approved plan will result in a Notice of Violation (NOV) issued by the Erosion Control Inspector with required corrective actions and a compliance due date for completion of corrective actions will be documented. Mitigation activities are enforced in the event off-site sedimentation damage is observed. NCDEQ, DEMLR receives a copy of every 32 NOV that is issued by the Erosion Control Division and NCDEQ, DWR is notified if sedimentation damage is observed to a jurisdictional water body. If the required corrective actions are not resolved by the compliance due date, a monetary fine, Stop Work Order, and/or Injunction may be imposed on the developer and/or contractor. In addition, the Inspections Division may withhold any certificates of occupancy until absolute resolution has been achieved. 11.1(d) Notification to the Responsible State or Local Government Agencies that have Enforcement Capabilities for eliminating Construction Site Wastes: During the course of conducting field inspections, Erosion Control Inspectors assess construction waste practices, specifically, in regards to potential adverse impacts to water quality. If Erosion Control staff determines that a contractor’s poor housekeeping practices possess a threat to water quality, staff will notify the Winston-Salem Regional Office of NCDEQ, DEMLR, if the site has a NCG01000 permit or located within unincorporated area of Forsyth County. If the site is located within the jurisdiction of a MS4-permitted entity (e.g. Clemmons, Lewisville, Kernersville, etc.), the respective stormwater authority is notified. Any pollutants that are directly (or indirectly) discharged, disposed, or illicitly-connected to storm drain systems (public or private-owned) or streams, which are located within the City of Winston-Salem’s municipal limits, are monitored and enforced by the city’s Stormwater Division. 11.1(e) Educational and Training Materials for Construction Site Operators: Erosion Control staff performs on-site and in-office educational discussions with licensed contractors, design professional, developers, and the general public as per service requests and/or issuance of violations. These educational discussions are very interactive and personal. Erosion Control staff provides guidance resources to contractors, developers, and the public by directing them to the City and NCDEQ-DEMLR’s websites. Erosion Control staff has also compiled and distributes digital technical guidance and design criteria resources through email or print by request. 11.1(f) Public Information: In 2005, City Council and the City Manager commissioned the creation and implementation of a centralized telephone call center/web-based complaint hotline for the citizens of the City of Winston-Salem. Known to the public as CityLink, this communication center receives citizen-generated e-mails or telephone calls regarding illicit activity within the City or County. The public can access CityLink on the City of Winston-Salem’s homepage of www.Cityofws.org.; it appears on the bottom portion of the website. The Erosion Control Division has been integrated into the CityLink system and implemented a response time of three days. The 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 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 of 1973. The Erosion Control Division responds to e-mails and received complaints from the hotline within three business days of first knowledge. 11.2 Eminent Domain Authority: The Erosion Control Division has an established procedure of requiring documentation of review and approval of a post-construction stormwater management plan by NCDEQ, DEMLR for all development activity within Forsyth County. Municipalities 33 that are excluded from this policy include Winston-Salem, Kernersville, Clemmons, and Lewisville, since each municipality has its own delegated post-construction stormwater program. This protocol provides NCDEQ, DEMLR the opportunity to collaborate with the Erosion Control Division concerning the approval of a post-construction stormwater management plan within the county where no post-construction stormwater management program exists. 11.3 Construction Site Runoff Control Annual Reporting Task Items for PY 2020 - 2021 1. The Erosion Control Division reviewed all submitted erosion control plans and performed corresponding onsite inspections to verify compliance. Erosion Control staff reviewed 118 erosion control plans and performed 3,207 onsite inspections for verifying site compliance. 2. The Erosion Control Manager and Assistant Stormwater Director performed a comprehensive gap analysis of DEMLR’s Soil Erosion and Sedimentation Control Model Ordinance. Currently, these staff members are incorporating model ordinance language into the Winston-Salem/Forsyth County Erosion Control Ordinance, Section 8.4. At the current rate, staff anticipates completing this gap analysis before June 30, 2022. 3. Erosion Control staff issued 38 notice of violations (NOVs) during FY 2020-2021. The average compliance percentage of all active construction sites was 75 percent, which can be attributed to frequent, intense storm events as well as the record-setting sheer volume of construction within Winston-Salem/Forsyth County. As a result, Erosion Control Inspectors were unable to perform as frequent site inspections, thus decreasing the overall average compliance percentage from FY 2019-2020. 4. Erosion Control Inspectors have referred eight construction site waste stream issues to the Winston-Salem Regional Office of NCDEQ, DEMLR (outside the municipal limits of Winston-Salem) and one to the Stormwater Division (inside city limits) to prevent pollutants from entering surface waters/MS4. 5. Erosion Control staff successfully resolved a total of 113 illicit sedimentation discharge/release claims, which are tracked through the city’s Citizen Service Request system, as an indicator of program effectiveness. 6. For FY 2020-2021, Erosion Control Division’s webpage had 25 total views, as an indicator of public interest. 34 12. POST-CONSTRUCTION SITE RUNOFF CONTROLS Objectives: 1. Manage stormwater runoff from new development/redevelopment that drains to the MS4 and disturbs an acre or more of land surface, including projects less than an acre that are part of a larger common plan of development or sale. 2. Provide a mechanism to require long-term operation and maintenance of SCMs. 3. Ensure controls are in place to minimize water quality impacts. 4. Permittee shall not be required to apply post-construction site runoff controls to entities that are exempt from permittee’s jurisdiction, including entities exempted under N.C.G.S. 113A-56. 12.1 BMP Summary Table BMP Measureable Goals PY 18-19 PY 19-20 PY 20-21 PY 21-22 PY 22-23 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 Stormwater Engineer 12.1(a) Post-Construction Storm Water Management Program: The Stormwater Division oversees and enforces the city’s post-construction stormwater management program. The City of Winston-Salem has supplemented previous water supply watershed regulations with current post-construction regulations for Class ‘C’ waters in order to address stormwater runoff from new and re-developed sites. The current Post Construction Stormwater Management ordinance was adopted by the City Council on September 19, 2008 and this ordinance applies to all development within our jurisdictional area (municipal boundary). The City’s Post-construction Ordinance can be located at https://library.municode.com/nc/winston- salem/codes/code_of_ordinances?nodeId=PTIIICOOR_CH75STMA_ARTIVPOCOST. 12.1(b) Strategies, which include SCM’s Appropriate for the MS4: Programs with development/redevelopment draining to Nutrient Sensitive waters: Drainage from the City of Winston-Salem ultimately flows to the Yadkin River, which is the main tributary for High Rock Lake. High Rock Lake has been classified as nutrient sensitive and currently has a TMDL in development for Chlorophyll A and turbidity. Currently, wastewater point sources are being considered for a waste load allocation (WLA) – not stormwater sources. Structural and non-structural SCMs will be utilized to address the requirements of 15A NCAC .0126 (10) (e). These SCMs will provide sediment removal, which ultimately reduces the nutrient inputs to receiving streams. Proper application and storage of fertilizers is being addressed through a Turf Management Certification, which is administered by the Stormwater Division and the Forsyth County Cooperative Extension Service in efforts to reduce nutrient loading to receiving streams. Fecal Coliform Source Control: The City of Winston-Salem coordinates with the Forsyth County Department of Public Health to reduce fecal coliform due to failing/or failed septic tank systems. This process requires the property owner to either connect to the POTW or repair/replace the septic tank system to effective operations. The City/County Utilities Commission (CCUC) has an extensive capital improvement program to rehabilitate failing sections of the sewer collection system. Stormwater staff works closely with the CCUC to resolve sanitary sewer overflows during dry weather screening activities or received citizen complaints. In addition, the City of Winston- Salem has an enforceable ordinance that requires pet owners to pick up fecal matter within its municipal boundaries. Section 6-12 in the City of Winston-Salem’s Municode contains the sanitation requirements for picking up dog feces, which is posted at https://library.municode.com/nc/winston- salem/codes/code_of_ordinances?nodeId=PTIIICOOR_CH6ANFO_S6-12SAREDO. 36 Non-Structural SCM’s: Currently, the City of Winston-Salem has implemented a comprehensive plan for growth – the Legacy Development Guide, which was adopted in 2012. Environmental quality is a key subject area, which is addressed with an objective to protect our local watersheds, wetlands, and streams. The City also has adopted local water supply watershed protection regulations, as required by NC DWQ. The Unified Development Ordinance regulates development in the Water Supply watershed areas of the City. Development is subject to zoning restrictions, erosion control measures, floodplain management and low density development provisions as they pertain to the water quality criteria of the Post-Construction Stormwater Control Ordinance such as recording of stream buffers where applicable and use of vegetative conveyances to the maximum extent practicable. Structural SCM’s: The City of Winston-Salem’s Post Construction Stormwater Management ordinance provides sizing and performance criteria for water quality SCMs. The City of Winston-Salem has also adopted the State’s Stormwater Design Manual as a technical guide for designing structural SCMs within its jurisdictional area and thus for use in also providing sizing and performance criteria, in combination with the ordinance provisions. The ordinance addresses both low density and high-density development scenarios as regards water quality attenuation. Low density developments (less than 24 percent built upon area, or less than two dwelling units per an acre) must meet all of the Minimum Design Criteria (MDC) of the NC DWR Stormwater Design Manual–Low Density Chapter, to the maximum extent practicable. Such items include but are not limited to recording of stream buffers where applicable and using vegetative conveyances to the maximum extent practicable. High density developments (greater than 24 percent built upon area and more than two dwelling units per acre) in addition to meeting all of the low density non-structural SCM requirements, to the maximum extent practicable, must also provide structural SCM’s. Any SCM or combination of SCM’s that are considered “Primary” SCMs per the Stormwater Design Manual and that can be effectively constructed in the Piedmont physiographic region may be approved by the Stormwater Engineer. In addition, the Post Construction Stormwater Management ordinance also includes a local requirement for water quantity standards if a development creates more than 20,000 square feet of new impervious area. If that is the case a development must either, (a) design structural SCMs in order to mitigate detrimental downstream effects of flooding and erosion in various design storm events, or, in lieu of management provide a “no adverse impact downstream study” if indeed a no adverse impact situation can be proven. 12.1(c) Deed Restrictions and Protective Covenants: The City of Winston-Salem, as previously mentioned, created, adopted, and implemented its post-construction ordinance on September 19, 2008. This ordinance includes comprehensive regulatory procedures 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 and these easements are referenced in the recorded Operation and Maintenance Agreements. Notice of violations, remedies, and monetary penalties are examples of regulatory tools contained within the post-construction ordinance that the Stormwater Division utilizes as enforcement mechanisms. For further reference, the City’s Post-construction Stormwater Control Ordinance (Chapter 75, Article IV) can be located at this link: https://library.municode.com/nc/winston- salem/codes/code_of_ordinances?nodeId=PTIIICOOR_CH75STMA_ARTIVPOCOST 37 12.1(d) Operation and Maintenance Plan: Stormwater staff inspect approved water quantity SCMs (pre-2008 post-construction ordinance adoption) as well as the Salem Lake Watershed (Water Supply IV Classification) SCMs on an annual basis. Next, Stormwater staff informs the owners of record of any deficiencies noted so that they may be addressed. Operation and Maintenance Agreements are required to be approved, recorded and implemented for all of the developments located within the Salem Lake Watershed area that require SCM(s) and the owners of such SCMs are bound to the terms of that agreement. The City currently has a spreadsheet that tracks all of the developments and redevelopments that have been submitted to the Stormwater Division for review and compliance with the Post Construction Stormwater Management ordinance. This spreadsheet includes a list of the development names, whether or not they are exempt from the ordinance and if exempt an explanation of why so, and if they are not exempt a description of what provisions of the ordinance they had to meet as in water quality – (low or high density), or water quantity, or both. This spreadsheet contains pertinent information, such as project submittal, review notes, date of permit issuance with corresponding number, the owners contact information of the stormwater management system, what developments we are currently still waiting on for as- built records to be submitted, what developments have submitted as-builts and hence are subject to submitting annual inspection and maintenance records, etc., so that Stormwater staff can efficiently check or reference any development and its criteria that may have been permitted, since the ordinance was adopted. The City also maintains “hard” files for all projects listed in this spreadsheet. SCMs, within the City limits jurisdiction and approved after the adoption of the post- construction ordinance, must have an Operation and Maintenance Agreement recorded as part of the post construction permit process that is binding on the SCM owner. The responsibility of SCM inspection and maintenance is placed on the designated SCM owner, or Homeowners Association/Property Owners Association, as applicable, who has signed the recorded Operation and Maintenance Agreement. The requirements for such inspections and maintenance are outlined in an Operation and Maintenance Manual that forms part of the overall Operation and Maintenance Agreement. Beginning after the certification of the as-built drawings for a permitted stormwater management system, the system must be inspected per the frequency described in this agreement by a suitably qualified professional on behalf of the owner. The owner must keep all records of these inspections and any maintenance activities that may have been necessary and submit these records to the Stormwater Director for review on an annual basis. The Stormwater Director or his designee may carry out his own inspection to validate such submitted records. All structural SCMs approved in accordance with the Post-Construction Stormwater Management ordinance must have a financial surety that meets the requirements of the ordinance provisions, in force prior to permit issuance. For a developer who wants to remain the party responsible in perpetuity for the long term Operation and Maintenance of the system, the surety shall equal four percent of the estimated construction cost of the Stormwater management system, verified by submittal of a sealed engineers estimate. This surety is held in a City maintained account and is non-refundable. The developer may apply for a loan from this account if needed to address system deficiencies. For SCMs that are to be owned and operated by a HOA or POA, then the surety that is required is in the form of an escrow account and escrow agreement. The developer establishes an escrow account at the time of permitting and deposits 15 percent of the estimated construction cost of the stormwater management system into this account, with the HOA/POA to add further funds in the future. An escrow agreement 38 must be approved and recorded during the permit process, which allows the City access to this escrow account, and its funds if needed should a SCM owner fail to comply with maintaining the system. The City also requires performance bonding or other cash securities, in accordance with the Salem Lake Watershed Environmental ordinance provisions, on SCMs proposed and located within the Salem Lake Water Supply Watershed area. 12.1(e) Educational materials and training for developers: Multiple training and information sessions were provided by Stormwater Division staff prior to and after the ordinance implementation in 2008. Educational materials provided include a permit application flowchart, example of design calculations and other supplementary information such as Operation and Maintenance Manual templates. These are available on the Stormwater Divisions website. The Stormwater Engineer and if needed the Stormwater Director, also make themselves regularly available to meet with developers at their request on an individual basis in the event that they need guidance on permit policies and procedures before submitting an application for a permit. The Stormwater Engineer is also a member of the City’s Technical Review Committee (TRC) and attends in person meetings held on a weekly and monthly basis to explain the Post Construction Stormwater Management permitting process to applicants looking to develop or redevelop property within the City limits and Salem Lake Watershed. The Stormwater Engineer has on average three such meetings (individual plus TRC combined) on a weekly basis. The Stormwater Engineer fulfills multiple meetings and information requests from developers, owners, and citizens either by phone or e-mail on a weekly basis outside of the in- person meetings. The City maintains a website on the Stormwater Divisions webpage that addresses the city’s post-construction permitting process as well as development requirements within the regulated Salem Lake Watershed area. This website is used as an educational tool available to all developers and SCM owners. The website contains items such as, a link to the Post Construction Stormwater Management ordinance, a link to the NC DWR Stormwater Design Manual website, the permit flow chart, a link to the permit application and checklists for submittal, templates for Operation and Maintenance Agreements and Manuals, design examples or SCMs, templates for inspections and annual compliance reports, a link to the electronic review submittal system and also a detailed FAQ section that attempts to address most, if not all of the questions that developers and SCM owners typically have. This website may be found at https://www.cityofws.org/794/Post-Construction-Stormwater-Management 12.2 Post-Construction Annual Reporting Task Items for PY 2020 – 2021: 1. The Stormwater Division has inspected 244 water quantity control SCMs during the past permit year. In the PY 2019-2020, 265 SCM’s were inspected. However, in this current PY 2020-202, access to 21 SCMs was restricted/denied by property owners due to Covid- 19 concerns and measures in place. 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’ = 21 (8.6%) b. The number of SCMS that are categorized with minor issues = 49 (20.1%) c. The number of SCMS with no deficiencies = 174 (71.3%) 39 2. Between implementation of the Post-construction Stormwater Control Ordinance in September 2008 and up to the end of this current permit period, the Stormwater Division has permitted a variety of structural SCMs that were required for high density developments under the water quality provisions of the ordinance as well as meeting the ordinance quantity provisions. Please note that as per Section 12.5 these stormwater management systems are inspected and maintained by the owners’ qualified representatives with records of such inspections and maintenance activities submitted annually to the Field Operations Director. The SCMs permitted along with the number of the SCMs are as follows: a. Wet Detention Basins = 50 b. Sand Filters = 50 c. Bio-Retention Cells = 25 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 = 61 In addition to these high-density developments in the same period, the Stormwater Division has also issued 90 permits for developments that were considered low density under the water quality provisions of the ordinance. No structural SCMs were therefore required, but these developments still had to meet the low-density provisions of the ordinance and the Stormwater design manual low density minimum design criteria. 3. During Permit Year of 2020 – 2021, the following information summarizes post- construction activities performed by the Stormwater Division: a. The number of plans reviewed = 47 b. The number of developments requiring water quality SCMs = 10 c. The number of developments requiring water quantity SCMs = 13 d. The number of no adverse impact studies submitted in lieu of management for quantity control = 3 e. The number of developments meeting the ordinance water quality provision exemptions = 18 f. The number of developments meeting the ordinance water quantity provision exemptions = 28 g. The number of developments grandfathered from the ordinance provisions based on a prior plan approval issued before the ordinance implementation in 2008, or, covered under a master Stormwater management plan submitted and approved, since the ordinance implementation = 1 h. The number of low-density projects =16 i. The number of high-density projects = 10 j. Sum of water quality SCMs = 17 (6 Sand Filters, 9 Wet Detention Basins, 1 Bay Filter and 1 Permeable Pavement System) k. Sum of water quantity SCMs = 17 (8 Wet Detention Basins, 3 Sand Filters, 3 Underground Management Systems and 3 Dry Detention Basins). 40 13.

Subsequently, staff prioritized these 42 municipal operations for SWPPP creation and implementation due to the magnitude and nature of activities that each municipal operation provides to the public. Since that time, the Stormwater Division provides professional services to City entities to create and implement BMPs for mitigating or eliminating exposure of pollutants to stormwater runoff. The following tables provide an overview of the City’s progression in reducing stormwater pollution from municipal operations, as of November 23, 2020.

The Stormwater Inspector prioritizes municipal facilities for an inspection ranking (annual frequency), based upon internal evaluation criteria, such as site size, nature of operation business practices, chemical or product quantities and/or toxicity, spill history, general permit issuance or status, etc. Once the inspection ranking list is finalized, the Stormwater Inspector evaluates the potential of each municipal facility or operation to generate potential pollutants. If the municipal facility/operation has been issued a general stormwater permit, the Stormwater Inspector determines onsite conditions and SPPP compliance with permit requirements. Basic municipal operations or facilities receive an abbreviated stormwater pollution plan, which concentrates on facility inspections, spill response procedures, general site maps, and employee training. If needed, the Stormwater Inspector refers the municipal facility to a qualified consultant for creation of a spill prevention, control, and counter measure plan (SPCC), which complements SPPP requirements (but not to replace). The inspection process focuses on current best management practices (BMPs) of chemical/substances (e.g. salt, gasoline, soil, etc.) storage, waste disposal, outdoor processes (e.g. vehicle and equipment washing), material un/loading, and automotive-related activities. In addition, Stormwater staff evaluates the effectiveness of structural BMPs, stormwater discharge outfall(s) condition, off-site erosion, and recommends corrective measures and/or BMP implementation (nonstructural or structural) for the facility. All generated inspection reports are posted on an internal shared drive as well as hard copies that are delivered to the Field Operations Director, Mr. Keith Huff. The Stormwater Division retains an electronic copy and hard copies of completed inspection forms. 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 2020; an update was finalized by the Stormwater Division during FY2020-2021 and is located at (G:\Industrial Inspection & Municipal Goodhousekeeping\MGH&PP Program\Municipal Facilities\Master Municipal.xlsx 13.1(c) Site Pollution Prevention Plans for Municipal Facilities and Operations: The Stormwater Division has identified 83 municipal facilities/operations that have the significant potential for generating polluted stormwater runoff. As of June 29, 2021, 61municipal facilities/operations 44 have implemented stormwater pollution prevention plans (SPPPs) to remove pollutant exposure to stormwater runoff (Tables 13.2 and 13.3). 22 municipal facilities/operations have been designated for site pollution assessments/inspections with SWPPP creation and implementation, if needed (Table 13.4). The Lowery Street Complex will be evaluated for vehicle-washing BMPs during the coming permit years. (G:\Industrial Inspection & Municipal Goodhousekeeping\MGH&PP Program\Municipal Facilities\Master Municipal.xlsx) 13.1(d) Spill Response Procedures for Municipal Facilities and Operations: For municipally owned facilities that are not required to apply for a NPDES stormwater permit, an abbreviated SWPPP has been created and implemented by City staff. A key component of this abbreviated SWPPP is spill prevention and response plan and procedures that are site-specific. SPPPs include site maps, facility inspections, GH and PM schedule, and SPPP certification. All SPPPs have site maps, facility inspections, good housekeeping and preventive maintenance schedule along with a SPPP certification. Each municipal operation/facility performs spill response training on an annual basis. Table 13.3 contains a list of municipal facilities/operations that have implemented an abbreviated SPPP. 13.1(e) Prevent or Minimize Contamination of Stormwater Runoff from all areas used for Vehicle and Equipment Cleaning: Upon inspection of each municipal facility or operation, structural and nonstructural BMPs are recommended for implementation. Stormwater staff promotes vehicle/equipment washing at the Lowery Street Complex. These washing bays discharge into an oil and water separator, which is connected into the sanitary sewer. Parking lots for abandoned vehicles will be evaluated for installation of an oil and water separator. If BMPs cannot be installed, the vehicle-washing activities will be performed in accordance with NPDES requirements; selected BMPs will be incorporated into an abbreviated SWPPP to reflect on-site practices and measures. 13.1 (f) Streets, Roads, and Public Parking Lots Maintenance: The Stormwater Division has worked in collaborative efforts with Winston-Salem Transit Authority 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 stormwater control measures, which receive inputs from public streets and roads. 13.1(g) Inspection and Maintenance (I&M) for Municipally-owned or Maintained Stormwater Control Measures (SCMs) and the Storm Sewer System: City Yard Field Operations has developed and implemented a comprehensive operation and maintenance (O&M) program for structural BMPs as well as the MS4. This O&M Program includes (but not limited to) these activities: • Street (right-of-way) structure maintenance (pipes and catch basins) – approximately 50 percent of total MS4 drainage structures are inspected and cleaned (if needed) once a year. Structure condition is denoted, prioritized for repairing, when required. • Street sweeping – the Sanitation Department ensures that the downtown business core streets are swept daily to remove pollutants from roadways. The Sanitation Department utilizes high efficiency vacuum street sweeper for maximum pollutant (e.g. trash, TSS, fecal coliforms, and nutrient) removal. In addition, numerous municipal facilities (e.g. Winston-Salem Transit Authority, City Hall North Parking Lot, etc.) utilize high 45 efficiency vacuum sweepers to remove any potential pollutants (oil and grease, TSS, fecal coliforms, and nutrients) at a designated service interval. • Structural SCMs maintenance: The Stormwater Division will inspect all municipally owned SCMs to assess current site conditions during CY 2021. Then, Stormwater staff will devise a prioritization plan for SCM maintenance or rehabilitation activities. Based on the results of the prioritization plan, the Stormwater Engineer and Field Operations Director will allocate funds and develop a critical path for returning SCMs to their designed, operating condition. Maintenance activities will include vegetative control of invasive species, sediment removal from forebays, trash and debris removal, and inlet and outlet cleaning services. 13.1(h) Staff Training: A web-based power point presentation and booklet is mandatory for all current and new municipal employees, which are not administrative positions, to view and synthesize awareness information regarding good housekeeping practices as well as illicit discharge identification and detection. Once training has been completed, City departments record each employee’s name and employee ID number for documentation purposes and submit these training logs to the Senior Community Educator. These educational materials serve for refreshing current employees’ awareness of pollution prevention techniques. In addition, the Stormwater Inspector performs inspections at specific municipal facilities, where enhanced staff training is warranted. Lastly, Jason H.

This list consists of industrial facilities that are permitted as defined by 40 CFR 122.26, SARA Title III, hazardous waste facilities, or identified as having or had an illicit discharge. The Stormwater Division updated this master list in November of 2020; updating will occur semiannually. All data will be stored digitally in our database and will be updated semiannually to maintain the most current inventory. This information can be located at G:\Industrial Inspection & Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Master.xlsx. 14.1(b) Inspection Program: Our current techniques are based upon revised 2006 EPA inspection methods, which include observations of effectiveness of nonstructural and structural BMPs, the facility’s stormwater collection system and stormwater discharge outfalls, site maps, and validation of written SPPP information to actual field observations. The City of Winston-Salem has prioritized industrial facilities within its municipal limits to be inspected. The Stormwater Division used the following sources to generate the list: 1. EPA’s Envirofacts Database for Toxic Release Inventory (SARA Title III) and RCRA (hazardous waste treatment, disposal, and recovery) facilities (updated semiannually) 2. NC Department of Energy, Mineral and Land Resources Database (General and Individual Permitted industrial facilities, as per 40 CFR 122.26) (updated semiannually) 3. The City of Winston-Salem Facilities’ Database (municipal operations/facilities that are permitted under 40 CFR 122.26) (updated semiannually, or as needed) 4. Illicit Discharge Reports (updated as needed and after each occurrence) When combining the above-mentioned databases, facilities that appeared multiple times due to their industrial activities and governmental regulations were ranked. As a result, the Stormwater Division assigned these industrial facilities with a ‘high-priority’ ranking due to the elevated probability of significant adverse impact to surface waters. The Stormwater Inspector will target these facilities for inspections; our goal is to inspect every permitted facility once every five years. Appendix B contains industrial and municipal facilities that were inspected during FY 2020-2021 by the Stormwater staff. 14.1(c) Evaluate Industrial Facilities discharging stormwater to the City’s MS4: During the SPPP review, Stormwater staff evaluates first flush data regarding benchmark values from the NPDES permit to determine to status before arrival. Once onsite for an inspection, a visual field observation of the stormwater collection system, current and past conditions of stormwater discharge outfalls (by means of qualitative monitoring records), and effectiveness of nonstructural and structural BMPs are observed. If needed, Stormwater staff will request copies of each sampling event to monitor results based upon the status of the permitted facility. Stormwater staff will update the master list to identify if the permitted facility is located within a TMDL watershed and/or discharges the TMDL pollutant of concern. The Stormwater Division maintains a good working relationship with the NC Division of Energy, Mineral and Land Resources (DEMLR), Winston-Salem Regional Office. A copy of every completed inspection and re-inspection form must be forwarded to Levi Hiatt, Assistant Regional Engineer, who handles stormwater related duties for the Winston-Salem Regional Office (WSRO) or the current Assistant Regional Engineer at the time of submittal. 49 14.2 Monitor and Evaluate Stormwater Discharges to Municipal Systems Annual Reporting Task Items for FY 2020 – 2021 1. The Stormwater Inspector conducted 18 inspections/reinspections of permitted industrial facilities that discharge stormwater runoff to the city’s MS4. 13 facilities successfully achieved compliance, as of June 30, 2021, to yield an annual compliance rate of 72 percent. Five facilities are in a status of ‘pending’ since time extensions were granted by the Stormwater Inspector. This information is located at G:\Industrial Inspection & Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Issues to be Resolved.xlsx. 2. All completed inspection forms of general permitted facilities, which was performed by the city’s Stormwater Inspector, was sent electronically to the Winston-Salem Regional Office of NC DEQ. As a result, the Stormwater Division reported all inadequate, tiered responses, based on the reviewed data and BMPs, if applicable, to NC DEQ. 3. During FY 2020-2021, the Stormwater Inspector examined nine industrial facilities within designated TMDL watersheds. This information is located at G:\Industrial Inspection & Municipal Goodhousekeeping\Indust_Inspect\City Industrial Information\Industrial Inspections.xlsx 4. The Stormwater Inspector updated the Stormwater Division’s industrial inventory master list on April 13, 2021. The Stormwater Inspector downloaded applicable facilities from EPA’s Envirofacts Database regarding Toxic Release Inventory, the Resource Conservation and Recovery Act (hazardous waste treatment, disposal, and recovery), and general and individual stormwater permitted facilities from NC DEQ’s website. Once downloaded, the database lists are consolidated and compared to the city’s existing master list – any absence facilities are included into the city’s master list.

Samples are collected in a composite method, except for fecal coliforms, which is a grab sample in accordance with 40 CFR 136.3. Composite samples are collected every 15 minutes in 100 milliliter aliquots for a 24-hour period. Parameters analyzed by a multiparameter meter are immediately obtained and recorded streamside. Appendix C contains all tabular data from the city’s fixed internal sampling program; Appendix D provides maps of these sampling locations. This can be found at the following location: G:\Techn_Projects_Files\Water Sampling\Stormwater Sampling Databases. 15.1(a) Water Quality Monitoring Program: On a quarterly basis, we collect instantaneous results at 17 monitoring locations, which have been strategically selected throughout the municipal boundaries of Winston Salem. The overarching goals of this monitoring program are detection of illicit discharges/releases as well as evaluating the long-term trend analysis of baseline water quality within non-TMDL watersheds. Samples are collected in dry and wet weather conditions to detect point sources of illicit discharges as well as determining pollutant loading during all weather conditions. Stormwater staff collects instantaneous water meter parameters, which include ammonia (mg/L), pH (standard units), dissolved oxygen saturation percentage, 51 dissolved oxygen (mg/L), temperature (degrees Celsius), conductivity (microsiemens per a centimeter), total dissolved solids (mg/L), and nitrate (mg/L). This can be found at the following location G:\Techn_Projects_Files\Water Sampling\Stormwater Sampling Databases. 15.1(a) TMDL Monitoring Program: On a quarterly basis, Stormwater staff collects instantaneous water quality parameters (the same parameters listed above) as well as laboratory grab samples of fecal coliforms at 22 strategic locations throughout Brushy Fork Creek, Peters Creek, and Salem Creek Watersheds. By collecting a large population of samples, Stormwater staff will be able to rank impaired stream segments by fecal coliform concentrations. Once stream segments are ranked, staff will systemically sample and identify the most impaired outfalls or subbasins for the potential of installing stormwater control measures. The city collects samples in both dry and wet weather conditions, since the state collected and analyzed fecal coliforms during these conditions for TMDL development. This methodology will allow Stormwater staff to perform comparative analyses for evaluating pollutant loading. Appendix E contains all TMDL monitoring data for FY 2020-2021 in tabular form. 15.2 Water Quality Assessment and Monitoring Annual Report Task Items for FY 2020-2021: 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 2020 – 2021, Stormwater staff collected 936 water samples with certified laboratory analyses and 432 water samples were collected within Salem, Brushy Fork, and Peters Creek Watersheds. 2. Stormwater staff will continue to perform quarterly water quality monitoring at 17 locations for the instantaneous results of ammonia, pH, and dissolved oxygen saturation percentage, dissolved oxygen, temperature, conductivity, total dissolved solids, and nitrate. Stormwater staff collected and analyzed 1,071 instantaneous parameters via portable YSI and Hach multiparameter meters during both dry and wet weather conditions. 3. Stormwater staff will continue to perform TMDL monitoring at 22 locations for the instantaneous parameters of ammonia, pH, and dissolved oxygen saturation percentage, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate. Total suspended solids and fecal coliforms parameters are analyzed at a North Carolina certified laboratory. Stormwater staff collected and analyzed 1,491 instantaneous and certified laboratory parameters in Salem, Peters, and Brushy Fork Creek Watersheds during dry and wet weather conditions. 52 16. TOTAL MAXIMUM DAILY LOADS (TMDLs) Salem Creek Watershed TMDL Objectives: 1. The permittee shall determine whether the MS4 discharges to receiving waters within a TMDL watershed and identify the pollutant(s) of concern (POC). For all TMDLs with a NPDES MS4 regulated stormwater waste load allocation (WLA) assigned to the permittee, the permittee shall determine whether the POC have potential to occur in MS4 stormwater discharges. 2. The permittee will utilize BMPs within the six minimum measures and the permittee’s TMDL Plan(s) to meet the permittee’s assigned NPDES MS4 regulated WLA identified in the approved TMDL to the maximum extent practical and to the extent allowable by law. 3. If subject to an approved TMDL with a NPDES MS4 regulated WLA assigned to the permittee, the permittee will be considered in compliance with the TMDL if the permittee complies with the conditions of this permit, including developing and implementing appropriate BMPs within the six minimum measures to address the permittee’s MS4 NPDES regulated WLA to the maximum extent practical (MEP). While improved water quality is expected outcome, the permittee’s obligation is to implement BMPs designed to address the NPDES MS4 regulated WLA assigned to the permittee to the maximum extent practical (MEP). The permittee is not responsible for attaining water quality standards (WQS). The Division expects attaining WQS will only be achieved through reduction from all point and nonpoint source contributors identified in the approved TMDL. TMDL Plans (as it pertains to the city of Winston-Salem’s approved plan): 1. If the permittee has an existing TMDL Plan designed to address the NPDES MS4 regulated WLA assigned to the permittee, that includes monitoring to evaluate progress, and which addresses the POC through the six minimum control measures; it satisfies the objectives of this Section. 16.1 Salem Creek Watershed TMDL BMP Summary Table BMP Measurable Goals PY 18-19 PY 19-20 PY 20-21 PY 21-22 PY 22-23 RESPONSIBLE POSITION/PARTY a Identify, Describe, and Map Watershed, Outfalls, and Streams A comprehensive master plan update of Salem, Brushy Fork, and Peters Creek Watersheds was in 2011.

X X X X X Assistant Stormwater Director Stormwater Operations Supervisor 16.1(a) Identify, Describe, and Map Watershed, Outfalls, and Streams: The City of Winston-Salem has completed comprehensive watershed masterplan updates of Salem, Brushy Fork, and Peters Creek Watersheds in 2011. GIS data was collected for these TMDL watersheds; survey-grade stormwater MS4 attribute data (e.g. structure type and elevation, pipe diameter and material, etc.) is collected by a contracted North Carolina Registered Surveyor. A consultant, HDR Engineering, performs QA/QC measures on the survey data, extrapolates pipe elevations to integrate flow directional trajectories for tracking IDDE discharges, and then, delivers a complete geodatabase to the Stormwater Division. During this inventory scan, the surveyor and HDR staff collects major discharge outfall (SDO) and stream data. If HDR staff encounters any dry weather flows at major SDOs, the Stormwater Division is notified, and staff evaluates the unidentified flow for pollutants. If pollutants are detected, Stormwater staff tracks and eliminates the illicit source. In addition, the Stormwater Division received hydraulic and hydrological modeling data as well as pollutant loading data for future SCM implementation projects. A revised reassessment date for these watersheds is scheduled for in FY 2022 - 2023. 16.1(b) Existing Measures: The city of Winston-Salem has implemented various stormwater control measures (SCMs) and nonstructural BMPs in order to reduce fecal coliform loading within the Salem Creek Watershed. During FY 2020-2021, the Stormwater Division continued to maintain these programmatic SCMs/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 – SCM identified for maintenance and replacement activities. 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. Illicit Discharge Detection and Elimination Program (IDDE) - the Stormwater Division performs stream sampling at 39 designated locations throughout Winston-Salem on a quarterly frequency. Of the 39 total 100 percent complete with on-going 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 55 locations, 22 sites are strategically situated in Salem, Brushy Fork, and Peters Creek Watersheds. programmatic, permit activities within the stream matrix is reduced, which facilitates the recovery of the biotic ecosystem at a more rapid rate. Stream Walking (IDDE Program Component) – For PY 2020-2021, the Stormwater Division has contracted HDR Engineering to perform stream-walking within designated, impaired waterways. SDO dry weather flows are referred to Stormwater staff for further investigation. 100 percent complete with on-going programmatic, permit activities 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. Public Education – Scoop-the-Poop campaign for fecal coliform reduction. 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 permit activities 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 pet waste collection stations within green spaces throughout Winston-Salem, including the downtown area. 35 of these 48 pet waste stations are 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 to retain soils on-site. 100 percent complete; continuous operation 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. SUSTAIN Modeling Study – HDR Engineering preformed an EPA SUSTAIN model for the Salem Creek Watershed. Eleven SCMs were identified for potential installation or retrofit opportunities. Washington Dog Park is the top prioritized water quality CIP – this project was completed in late 2019. 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. 56 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 City Yard, Field Operations assesses and prioritizes earthen conveyance swales 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 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. The Stormwater staff offers advice to residential property owners regarding stream stabilization techniques and practices to reduce erosion. 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. 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 sand filter. 100 percent complete and in continuous operation. SCM has been designated for first year inspection with possible maintenance activities. The Washington Dog Park is located within 75 feet of Salem Creek’s top of bank. The park is the only and heavily used dog recreational area within Winston-Salem. A pet waste receptacle is positioned at the park’s only access point. 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. 100 percent complete and in continuous operation. SCM has been designated for inspection and maintenance activities. 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. These land uses have potential to export nutrients, fecal coliforms, thermal, and metal pollutants, thus validating the need for this SCM. 16.1(c) Assessment of Available TMDL Monitoring Data: The Stormwater Division performed a programmatic review of its TMDL Sampling Plan in September 2019. One of the salient points of the review included the lack of a substantial fecal coliform data population. As a result, the Stormwater Division designated 22 in-stream monitoring locations throughout Salem, Peters, and Brushy Fork Watersheds. Stormwater staff collects water quality samples on a quarterly basis; however, COVID caused two missed sampling events during 2020. Thus, Stormwater staff has collected three TMDL sampling events since September 2019. As more data becomes 57 available, Stormwater staff will perform basic statistical analyses to rank the stream segments by the level of impairment (i.e. the higher the geometric mean at the sampling location, the more level of pollutant loading). A preliminary stream ranking order will be included in the Stormwater Division’s 2020-2021 Annual Report. As more data is collected, the Stormwater Division will perform annual trend analysis to observe increasing, decreasing, or constant fecal coliform concentrations within Brushy Fork Creek, Peters Creek, or Salem Creek Watersheds. 16.1(d) TMDL Monitoring Program: On a quarterly basis, Stormwater staff collects instantaneous water quality parameters (dissolved oxygen - concentration and percent saturation, total dissolved solids, conductivity, temperature, pH, nitrate, and ammonia) as well as certified laboratory results of fecal coliforms at 22 strategic locations throughout Brushy Fork Creek, Peters Creek, and Salem Creek Watersheds. By collecting a large population of samples, Stormwater staff will be able to rank impaired stream segments by fecal coliform concentrations. Once stream segments are ranked, staff will systemically sample and identify the most impaired outfalls or subbasins for the potential of installing stormwater control measures. The city collects samples in both dry and wet weather conditions, since the state collected and analyzed fecal coliforms during these conditions for TMDL development. This methodology will allow Stormwater staff to perform comparative analyses for evaluating pollutant loading. 16.1(e) 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 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) 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 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. Senior Community Educator 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. Senior Community Educator 58 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. Senior Community Educator Evaluate municipal operations and facilities (e.g. Winston Golf Course, City Yard Dewatering Facility, etc.) 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. Stormwater Inspector Other City Divisions Explore new methodologies of locating and removing failing septic tank systems from discharging into receiving waters/MS4. By utilizing GIS tools in conjunction with issued septic tank permits, the Stormwater Division anticipates being able to proactively locate potential ‘hot spots’ of septic tank failures. Forsyth County Department of Health Stormwater Operations Supervisor Stormwater Technicians Perform water quality sampling from municipally owned properties SDOs that have a great potential to discharge fecal coliforms. By validating fecal coliform pollutant concentrations, the Stormwater Division can 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 Stormwater Inspector Stormwater Operations Supervisor Explore the potential to perform street sweeping activities in ‘hot spot’ areas (e.g. Sanitation Truck Yard, Hanes Mill Landfill) within impaired watersheds that focuses on fecal coliform reduction. Due to the nature of some municipal operations, fecal coliform bacteria have the potential to be discharged into receiving streams. By commencing street sweeping activities at these selected areas, the city will eliminate or mitigate pollutant loading to surface waters. Stormwater Inspector Other City Divisions 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. Utilities Construction & Maintenance Division Field Operations, City Yard 16.1(f) 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 F contains a five-year capital improvement project (CIP) list of proposed structural SCMs; 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 59 Sanitation Collection Truck Storage Yard – stormwater runoff is conveyed from Sanitation’s garbage truck storage lot into three sand filters for infiltration treatment. These SCMs are designed to infiltrate stormwater runoff through an engineered sand media to facilitate pathogen die-off, thus, reducing fecal coliform loading to Brushy Fork Creek. As required, the three sand filters will be inspected by certified professional in FY 2021-2022. Based on inspection results, maintenance activities will be performed by city resources or subcontracted to an external entity. TMDL Monitoring Plan – a program evaluation was performed by staff, which revealed several information gaps within the monitoring plan. To devise a clearer and effective strategic TMDL masterplan, the Stormwater Division has implemented more sampling locations to identify fecal coliform sources 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. New sampling procedures have been finalized with Stormwater staff with training completed regarding program amendments. The new sampling procedures were implemented in September 2019. Salem Creek Structural Control Masterplan – a consultant performed an assessment of the Salem Creek Watershed to generate a prospective list of sites for SCM placement. Once identified, computer modeling was used to develop a priority ranking system for SCM 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 can validate the cost-effectiveness and removal efficiency to the public, elected officials, and the City Manager’s Office. In addition, the Stormwater Division may develop a long-term capital improvement project performa spending plan for Council’s approval. This SCM masterplan was completed and delivered to the Stormwater Division in July of 2013. The first water quality project, Washington Dog Park Sand Filter, was completed and operational in January 2020. 15 sites are remaining for SCM retrofit/installation opportunities. City Yard Dewatering Facility – as a byproduct of street sweeping and MS4 cleaning operations, the collected debris, trash, and particulate matter must be dewatered prior to disposal at the appropriate, licensed landfill. The leachate from street sweeping and MS4 cleaning activities is elevated in nutrients, metals, BOD, and fecal coliform pollutants. By placing dewatering operations under roof, and discharging leachate to the sanitary sewer, the exposure of these pollutants to the open environment will be eliminated. The City Yard Dewatering Facility will be constructed in the Salem Creek Watershed, where current dewatering operations reside. This capital improvement project is estimated to cost approximately $250,000 with a projected completion date of December 2023. 16.1(g) 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 proposed the below-posted means for validating pollutant reduction loading to the effectiveness of implemented control measures. These methods include: • Perform water quality sampling for targeted pollutants at the inlet and outlet points of a SCM during the first flush portion of a storm event. Once a SCM is constructed and operational, Stormwater staff will perform, at a minimum, one confirmation sampling event, to validate pollutant reduction. The pollutant removal efficiency will be recorded on a spreadsheet; an annual pollutant reduction will be extrapolated for the SCM. 60 • Continue to submit completed workload data and programmatic task items to DEMLR via the Annual Report. • Long-term, in-stream pollutant data will need to be collected, at designated sampling locations, to observe pollutant deductions in wasteload allocation reductions within subwatersheds. Due to the dynamic nature of biological ecosystems as well as the large percentage of pollutant reduction required, the Stormwater Division needs a substantial data population to observe percent reductions. As the number of SCMs/BMPs increases within a subwatershed, the Stormwater Division anticipates that the observable, pollutant trend line should decrease. • Whenever possible, use scientific journal articles (or similar professionally peer-reviewed literature), quality controlled/assured laboratory analyses (from a North Carolina certified laboratory), or professional engineered-sealed material when validating reduction methodologies for this TMDL Implementation Plan. Any best professional assumptions must be qualified with footnotes within supporting documents. 16.2 Salem Creek Total Maximum Daily Load (TMDL) Annual Report Task Items for FY 2020- 2021: 1. 825 linear feet of restored drainage ditches within the Salem Creek Watershed (and contributing tributaries) for total suspended solids reduction. 2. During TMDL sampling, instantaneous results of ammonia, pH, and dissolved oxygen percent saturation, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate are collected. This information is located at G:\Techn_Projects_Files\Water Sampling\Stormwater Sampling Databases\Current. Stormwater staff collected 606 instanteous meter results - 100% of all detected illicit discharges were eliminated. 3. HDR staff walked over 30 miles of streams within Salem Creek, Peters Creek, and Brushy Fork Watersheds during dry weather conditions. Four major outfalls were suspected potential illicit discharges: further investigative activities (including multiparameter instanteous readings) by Stormwater staff proved no present illicit discharges. 4. The Stormwater Division is furnishing all FY 2020-2021 fecal coliform data from all 22 TMDL sampling locations. This data set is contained in Appendix E. 5. Stormwater staff calculated the geometric mean (expressed in units of cfu/100 mL) for the 22 TMDL sites and created a priority ranking, based upon the most polluted stream segments. The top three polluted stream segments (during dry weather conditions) are Peters Creek at the Antique Dealership (3,862), Burke Creek at Northbridge Road (Salem Creek Watershed, 3,795), and Brushy Fork at Reynolds Park Road (2,715). For wet weather conditions, the top impaired stream segments are Peters Creek at Glenn Avenue (93,800), Bowen Branch at 25th Street (Brushy Fork Creek Watershed, 19,135), and Peter Creek at the Antique Dealership (16,933). Based on the FY 2020-2021 TMDL fecal coliform sampling data, Peters Creek Watershed is the most impaired watershed. Within the Peters Creek Watershed, the most impaired stream segment from Peters Creek at Hanes Park to Peters Creek at the Antique Dealership. For FY 2021-2022, the Stormwater Division will concentrate reconnaissance and stream monitoring activities to isolate pollutant-generating sources. 61 6. The city of Winston-Salem partnered with Stormwater Smart of the Piedmont Triad Council for mass media services. Litter and pet waste were the two main pollutants of concern for the mass media campaign. Over 10,235,000 impressions of media placement services were recorded; 95,537 social media impressions (Facebook, Instagram, and www.stormwatersmart.org) were tabulated. Within Winston-Salem, all media outlets (TV, radio, online advertisements, and Twitter) had 2,139,950 impressions during FY 2020-2021. 17,836 social media (in-house Facebook, in-house Instagram, and in-house website activity) impressions were recorded within the city of Winston-Salem’s internal social media outlets. 7. Stormwater and Information Systems (I.S.) staff have successfully extracted potential septic tank locations from the city’s utility bill system. Once this comprehensive list has been properly formatted and verified, Stormwater and I.S. staff will create a search function within the city’s GIS to show septic tanks within 500 feet of identified streams. Stormwater staff will perform stream-walking investigative activities and downstream monitoring to proactively detect and eliminate failing septic tank systems. This task item will be completed by the end of FY 2021- 2022. 8. City Council approved the funding for a new dewatering facility at City Yard, where street sweeping wash water and MS4 cleaning debris leachate will discharge into the sanitary sewer system. The new facility should be constructed and operational by December 2023. 9. The Stormwater Inspector performed two inspections of industrial and municipal facilities within the Salem Creek, Peters Creek, and Brushy Fork Watersheds that have the potential to discharge fecal coliforms. 16.3 Muddy Creek Watershed TMDL In November 2011, the North Carolina Department of Environment and Natural Resources (NCDENR) issued a final report for turbidity impairment of the Muddy Creek Watershed. The Muddy Creek TMDL designates the City of Winston-Salem’s MS4 as a significant contributor of turbidity (i.e. total suspended solids) pollution. A waste load allocation (WLA) was not assigned to the City’s NPDES permit; however, total suspended solids loading (ton per a day) must be reduced by 58 percent. In accordance with its NPDES permit, the city must evaluate strategies and adapt BMPs to reduce TSS loading within the Muddy Creek Watershed. The Stormwater Division performed a BMP assessment and selected appropriate reduction strategies to mitigate TSS pollution. These selected BMPs are posted in the below table. 16.4 Muddy Creek Watershed TMDL BMP Summary Table Selected BMP Strategies Explanation of Desired Outcomes Inspection Regime for permitted Construction Sites – In order to ensure off-site sedimentation does not occur, Erosion Control staff performs routine field inspections for site compliance. Muddy Creek Watershed is experiencing an influx of construction activities due to land availability and improving economic conditions. Erosion Control staff inspect and maintain site measures. As a result, the Erosion Control Division anticipates a reduction of off-site sedimentation. 62 Comprehensive Watershed Masterplan Update – The Stormwater Division contracted HDR Engineering to inventory, assess, and model the Muddy Creek Watershed. A consultant has completed a comprehensive watershed masterplan of the Muddy Creek Watershed in 2017. This masterplan evaluated numerous TSS exportation sources, such as stream bank erosion, compromised infrastructure and outfalls, and potential areas of future development. This tool guides staff to assess, prioritize, and repair identified projects, thus ultimately removing sedimentation sources. Industrial Inspection Program - In accordance with NPDES requirements, Stormwater staff performs facility inspections to eliminate pollutant loadings to the MS4 or local streams. The city of Winston-Salem has 90 state-permitted facilities within its municipal boundaries. Most of these facilities must monitor TSS concentrations within their stormwater discharge. If benchmark values are exceeded, the permitted facility must implement additional BMPs to reduce TSS loading. Municipal Goodhousekeeping Inspection Program – In accordance with NPDES requirements, Stormwater staff performs municipal facility/operations audits to eliminate pollutant loadings to the MS4 or local streams. Stormwater staff assesses municipal operations for reducing or eliminating TSS pollutant loadings to the MS4/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. Ditch Repair and Stabilization Program – the Streets Division hires a private contractor to repair and stabilize ditches within the public right-of-way. Field Operations 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 offsite sedimentation to receiving waters. Fixed Interval Monitoring Sites – the Stormwater Division samples 13 fixed interval locations, which are placed the bottom of each watershed (or major subwatershed) to observe the accumulated effects sediment sources. Total suspended solid (TSS) samples are collected during dry and wet weather conditions, so staff can determine the most sediment-laden waterways within the city of Winston-Salem. By collecting and evaluating TSS concentrations at the lower drain point from each major watershed (or subwatershed); Stormwater staff will be able to determine the most sediment-laden waterways. A ranking of most impaired streams will be developed, and then staff can commence up-gradient stream sampling of the most impaired segments. Lastly, Stormwater staff should be able to isolate sediment sources within subbasins for placement of appropriate stormwater control measures. Illicit Discharge Detection and Elimination Program (IDDE) - the Stormwater Division performs stream sampling at 39 designated locations throughout Winston-Salem on a quarterly frequency. Stormwater staff monitors for any detectable illicit discharges, which includes sediment sources. Staff has created a comprehensive, watershed-specific library of pollutant parameters, based upon historical laboratory data. For Muddy Creek Watershed, staff will commence an illicit discharge investigation, if total dissolved solids (a pollutant parameter surrogate) exceed 400 mg/L or visible sediment sources (during dry weather conditions). 16.5 Muddy Creek Total Maximum Daily Load (TMDL) Annual Report Task Items for FY 2020- 2021 1. Stormwater staff will review HDR Engineering’s field assessments of Muddy Creek and develop a prioritization plan for potential projects. A targeted sediment source, destabilized streambanks, is potential candidate for project consideration during FY 2021-2022. 63 2. The Stormwater Inspector performed three inspections of industrial and municipal facilities within the Muddy Creek Watershed that have the potential to discharge total suspended solids. 3. 195 linear feet of restored drainage ditches within the Muddy Creek Watershed for total suspended solids reduction. Throughout the city of Winston-Salem, a total of 3,347 linear feet of drainage ditches were stabilized and restored. 4. The Sanitation Division swept 2,798 linear miles of street sweeping activities for public roadways within the city of Winston-Salem. 5. The top three polluted stream segments within the city of Winston-Salem (during dry weather conditions) are Mill Creek at Shattalon Drive (89.00), Silas Creek at McGregor Road (20.4), and Muddy Creek at Frye Bridge Road (20.10) based on the annual arithmetic mean. For wet weather conditions, the top impaired stream segments are Silas Creek at McGregor Road (59.73), Lower South Fork Creek at Ebert Road (47.90), and Muddy Creek at Frye Bridge Road (40.93). It is noteworthy that two out the three sites, Silas Creek at McGregor Road and Muddy Creek at Frye Bridge Road, are the most polluted, in term of TSS concentrations. For FY 2021 – 2022, Stormwater staff will focus investigative efforts within these two impaired stream segments for identification of sediment-laden sources. 6. During water quality sampling activities, instantaneous results of ammonia, pH, and dissolved oxygen percent saturation, dissolved oxygen concentration, temperature, conductivity, total dissolved solids, and nitrate are collected. This information is located at G:\Techn_Projects_Files\Water Sampling\Stormwater Sampling Databases\Current. Stormwater staff collected 444 results of instantaneous meter readings. 7. The Stormwater Division successfully resolved ten illicit discharges within the Muddy Creek Watershed. 8. The city of Winston-Salem partnered with Stormwater Smart of the Piedmont Triad Council for mass media services. Litter and pet waste were the two main pollutants of concern for the mass media campaign. Over 10,235,000 impressions of media placement services were recorded; 95,537 social media impressions (Facebook, Instagram, and www.stormwatersmart.org) were tabulated. Within Winston-Salem, all media outlets (TV, radio, online advertisements, and Twitter) had 2,139,950 impressions during FY 2020-2021. 17,836 social media (in-house Facebook, in-house Instagram, and in-house website activity) impressions were recorded within the city of Winston-Salem’s internal social media outlets. 64 APPENDIX A 65 Appendix A Field Operations Department Stormwater and Erosion Control Divisions Organizational Chart 66 Keith Huff Field Operations Director Andy Allen Assistant Stormwater Director Ladonta Clark Stormwater Operations Supervisor Vacant Stormwater Inspector Rob Dockery Stormwater Technician Nick Hole Stormwater Technician Matt Osborne Erosion Control/Floodplain Manager Kent Wall Erosion Control Inspector David Evans Erosion Control Inspector Wesley Williams Erosion Control Inspector Ronnie Holbrook Erosion Control Inspector Vacant Special Projects Coordinator Todd Love Sr. Civil Engineer Joe Fogarty Stormwater Engineer Vacant Senior Community Educator Vicki Pigg Stormwater Operations Analyst Neil Uldrick Civil Engineer 67 APPENDIX B 68 Appendix B FY 2020-2021 Industrial & Municipal Goodhousekeeping Inspection List Permit Number Facility Name Owner Type NPDES Permit Category Permit Status * NCG080801 Fleet Services Municipal Government Transportation with Vehicle Maintenance Active MGH/ D NCG080023 Winston-Salem Transit Authority Non-Government Used Motor Vehicle Parts Stormwater Discharge COC Active D NCG200349 Omnisource Southeast, LLC.
