As the program continues and experience is gained as to the successfulness of program elements, modifications and additions may be made to enhance the program effectiveness. Any changes to the program are subject to prior review and approval by the permitting agency. It shall be noted that the City of Belmont has a Watershed Water Supply IV Program and a Phase II Stormwater Program within the City Limits. Belmont is located between the main branch of the Catawba River and the South Fork of the Catawba River. The center of the City lies approximately halfway between these two major water courses, with the tributary divide between the two basins running north and south through the downtown. As such, stormwater runoff from the City flows in approximately equal portions either to the east toward the Catawba River or westerly to the South Fork. The eastern portion of the City is subject to the Watershed Water Supply IV rules. The Watershed Water Supply IV rules are regulated and enforced by the City of Belmont, while the western portion of the City is subject to Phase II Stormwater rules. The Phase II Stormwater Post Construction and Construction Site Runoff rules, through adoption of the Gaston County Stormwater Ordinance, Gaston County Soil Erosion and Sedimentation Control Ordinance, and Inter -local Agreements with Gaston County, are regulated and enforced by and in cooperation with, Gaston County Natural Resources (GNR). 1. Population and Estimated Growth: Belmont's population per a certified estimate from State demographer is 12,558 as of July 1, 2019. The City is not subject to seasonal variations in population. The annual population growth rate for the MS4 service area is 1.48 percent. This has been calculated on the basis of the relative change between the 2007 and 2015 Office of State Budget and Management population data. More recent population data is not available. 2. Jurisdictional and MS4 Service Areas: The City of Belmont is comprised of 10.1 square miles within its current City Limits. In addition to the area within the city limits, Belmont has planning jurisdictional authority within two areas bounding the City on the south and west. These extra -territorial jurisdiction (ETJ) areas total 3.7 square miles. The MS4 service area is the area within the current City Limits. Belmont does not have authority to operate or maintain storm sewer systems outside its municipal corporate boundaries. 3. MS4 Conveyance System: Belmont is located between the main branch of the Catawba River and the South Fork of the Catawba River. The center of the City lies approximately halfway between these two major water courses, with the tributary divide between the two basins running north and south through the downtown. As such, stormwater runoff from the City flows in approximately equal portions either to the east toward the Catawba River or westerly to the South Fork. Although a separate storm sewer system exists throughout the city, the system is not extensive. There is a heavy reliance on local streams, creeks and ditches to convey runoff to the rivers. Maintenance of the MS4 is on an "as needed" basis to unclog pipes, clean catch basins, and otherwise CITY OF BELMONT 2 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 maintain the system. Under current City regulations and practice, only conveyances within City rights of way and easements are maintained. NCDOT maintains stormwater conveyances in rights of way falling under their jurisdiction, also on an "as needed" basis. 4. Land Use Composition Estimates: The following is an estimate of the percentage of the MS4 service area that consist of residential, commercial, industrial, and open space land uses: Residential 75% Commercial 10% Industrial 5% Open Space 10% Total 100% These estimates were obtained using CAD methods from Gaston County GIS mapping data. Commercial and industrial land uses were calculated on this basis from the city's official zoning map which is maintained by the County GIS Department. Open space consists of the approximate areas of the many parks and recreational areas (sports fields) in the City. The areas of the commercial, industrial and open space were subtracted from the total jurisdictional area to derive the residential land uses. These estimates are based on zoning designations. Vacant property was classified by zoning district and accordingly is included in the four categories. The areas of Institutional land uses such as Belmont Abbey College, Sisters of Mercy Campus, four public schools and the many churches in Belmont were included in the residential category. CITY OF BELMONT 3 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 5. Receiving Streams The entire jurisdictional area of the MS4 lies within the Catawba River Basin.

TMDL Identification: 6.1. BMP Summary Table (Appendix A) 6.2. Lake Wylie TMDL Nutrient Management — In 1995 a TMDL for chlorophyll a was developed for Lake Wylie. This TMDL set a total phosphorous (TP) and total nitrogen (TN) limits for WWTPs discharging to Lake Wylie. The City of Belmont Wastewater Treatment Plant (WWTP) has Total Phosphorus and Total Nitrogen discharge limits set under its individual NPDES Permit. Pretreatment Inspections, Testing, and Cleaning Schedules for two industries, and all restaurants and car washes connected to the sanitary sewer system are performed, scheduled, and monitored by the Wastewater Pretreatment Division to ensure that acceptable levels of Phosphates, Nitrogen, BOD, grease, etc. are entering the WWTP. This TMDL does not have an approved WLA assigned to stormwater/non-point sources. The City is working to reduce nutrients from non -point sources by tailoring existing BMPs to better target nutrient loading. 6.2.1. Public Education and Outreach — Spotlight erosion and sedimentation control, lawn care and disposal of yard waste, and illicit discharges in educational materials and at educational events to inform citizens of the negative impacts total phosphorus and total nitrogen can have on water quality. Promote the Stormwater hotline/helpline and encourage citizens to report observed or suspected pollution. 6.2.2. Public Involvement and Participation — maintain the volunteer storm drain labeling program with efforts to increase participation. Promote the Stormwater hotline/helpline and encourage citizens to report observed or suspected pollution. Recommend to the Stormwater Committee starting a Volunteer Stream Clean -Up or Adopt -A -Stream Program. 6.2.3. Illicit Discharge Detection and Elimination (IDDE) — maintain the IDDE Program and with efforts to increase the number of stream walks and system inspections to find and eliminate illicit discharges and/or connections. Promote the Stormwater hotline/helpline and encourage citizens to report observed or suspected pollution. 6.2.4. Construction Site Runoff Controls — Maintain construction site inspections and reporting to Gaston Natural Resources. Gaston Natural Resources permits and enforces the E&SC Ordinance. 6.2.5. Post -Construction Site Runoff Controls — maintain the current program and ensure that new development, and redevelopment, subject to CITY OF BELMONT 7 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 Stormwater Ph II Rules or WSIV Rules are following through with approved plans, BMP inspection and maintenance, and annual reporting. 6.2.6. Pollution Prevention and Good Housekeeping for Municipal Operations — Maintain and evaluate Facility Stormwater Pollution Prevention Plans (SWPPPs) to work better for each unique facility. Maintain Street Sweeping Program. 6.2.7. Total Maximum Daily Loads (TMDLs) — monitor NCDEMLR List of Approved TMDLs to stay abreast of any new TMDLs that the City of Belmont may become subject to. Update annually. 6.3. Mercury Statewide TMDL — In 2012, NCDENR developed a statewide mercury TMDL to determine how wastewater discharges, in -state air sources, and out-of- state air sources contribute to the surface water mercury load. This TMDL acknowledged that most mercury in stormwater comes from atmospheric deposition and that concentrations in stormwater are typically within the same range as mercury concentrations in rainwater, between zero and 10 ng/L. No MS4 NPDES WLA for mercury was assigned for this TMDL.

Public Education and Outreach 13.1. BMP Summary Table (Appendix A) 13.2. Goals and Objectives: The Public Education and Outreach Program works to inform the public on what stormwater is, how it affects water quality, why this is important, and what the public can do to prevent and reduce pollution in stormwater. Many residents are unaware that the stormwater system is not connected to the sanitary sewer system and that runoff is not treated before draining into local streams and rivers. Communicating this simple fact is imperative to affecting public behavioral change. Once the public is aware of stormwater and its potential for pollution, the Public Education and Outreach Program works to equip the public with practices they can use to help protect water quality. 13.3. Target Pollutant Sources: The City is not aware of any significant target pollutant sources but will concentrate on used oil disposal; proper handling, applications and disposal of lawn and insect chemicals; sediments; and disposal of household cleaning chemicals, paint, illicit discharges, etc. As the City proceeds through this SWMP, it is expected that the impact of these sources of pollution will be better defined and other significant sources identified. Because the education program will be continuous during the permit period, and presumably during subsequent permit renewals, the content of the educational materials and presentations will change to meet the objectives of the SWMP. 13.3.1. Lawn Care Activities — Improper application, handling and storage of lawn care products such as pesticides, herbicides and fertilizers can result in the discharge of pollutants to the storm drain system. Improper disposal of grass clippings and leaves can negatively impact water quality by depleting oxygen levels in waterways. Significant residential development exists in the City of Belmont with the potential for negative water quality impacts associated with improper lawn care activities. 13.3.2. Improper Disposal — Improper disposal can result in the discharge of a variety of pollutants to the storm drainage system. This can be a problem at construction sites where paint and other construction wastes are generated and in established commercial and residential areas where used oil, grease, animal waste, household cleaners, paints and a variety of other pollutants can be a problem. 13.3.3. Poor Housekeeping — Poor housekeeping can result in the discharge of petroleum products, miscellaneous chemicals and other wastes to the storm drain system and surface waters. This is usually a problem at commercial facilities. 13.3.4. Erosion — Poor erosion control and soil stabilization at construction sites, utility maintenance, and residential and commercial lawns results in sediment discharges to the storm drainage system. 13.3.5. Pet Waste — Pet waste contains bacteria, viruses, and parasites that are harmful to human health. Contact with stormwater runoff carries these bacteria, viruses, and parasites into waterways. CITY OF BELMONT 17 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 13.4. Target Audiences: The target audiences for the education program include those likely to have significant stormwater impacts. Homeowners were selected as a primary target for the educational program due to the significant positive and negative impacts they could have on water quality. This is also the group that will most likely engage in activities such as disposal of auto oil and household wastes, disposal of yard wastes, application of fertilizers, pesticides and herbicides, pet waste, etc. Commercial facilities such as gas stations, car washes, restaurants, shopping centers and industrial warehouses/plants were targeted for the educational program due to the significant impacts they could have on water quality by potentially improperly handling and disposing of wastes, making illicit connections to the storm drain system, and practicing poor housekeeping at their facilities. Through education, the City is hopeful that it can inform and advise the public of the small behavioral changes that can be made to improve water quality. 13.5. Residential Issues: 13.5.1. Lawn Care — Yard waste disposal such as leaves, limbs, brush, grass clippings, etc. are to be placed at curb for pickup by the City of Belmont, but often the debris is placed in the street or in the curb -line. Rain events can wash leaves, limbs, yard debris into the storm drains which clog storm drains as well as having potential to be conveyed to waterways. As these items decompose in waterways they deplete oxygen levels in the water. 13.5.2. Improper Disposal/Illegal Dumping of Hazardous Household Materials such as paints, cleaners, other household chemicals, and used vehicle oil and fluids often contain toxins, heavy metals, and nutrients. These pollutants can negatively impact water quality, wildlife, and human health. 13.5.3. Erosion — Bare areas on lawns and common open spaces can lead to sediment discharges to the storm drain system.

Illicit Discharge Detection and Elimination 15.1. BMP Summary Table (Appendix A) 15.2. Regulatory Mechanism: The western portion of the City of Belmont, Phase II Stormwater area, has been under the Gaston County Stormwater Ordinance since July 7, 2007. The Gaston County Stormwater Ordinance includes a section on Illicit Discharge Detection and Elimination and has been enforced by Gaston County officials. However, the eastern portion of the City of Belmont, Watershed Water -Supply IV area, was not covered by the Gaston County Stormwater Ordinance. On September 15, 2009 the City of Belmont adopted a separate Illicit Discharge Detection and Elimination Ordinance, which is enforceable by the City of Belmont and encompasses the entire jurisdictional area. 15.3. Storm Sewer System Map: Several years ago, the City undertook to develop a storm sewer system atlas in anticipation of the impending NPDES Phase I I regulations. The field inspections were completed by summer interns and system elements were approximately located on existing sanitary sewer and water main maps. The information was transferred to a digital storm sewer map. These maps are checked for accuracy as the ongoing illicit discharge detection and elimination program and MS4 inspections are implemented. As the MS4 is inspected, the existing maps are updated by hand with the information received. As significant information is obtained, the mapping will be computer updated and published. 15.4. Dry Weather Flow Screening is incorporated into the Stormwater System Inspection and Mapping Program (SWIM). As system elements and outfalls are inspected and mapped on GPS, dry weather flow screening is performed. Inspections are performed, at minimum, twenty-four hours after a rain event to ensure flows are not stormwater runoff. Observed flows at any system element triggers an Illicit Discharge/Connection Investigation. Procedures for detecting dry weather flows and conducting investigations of identified illicit discharges are outlined in the IDDE section of the SWMP. The City maintains electronic and hard copy files of all investigations of identified illicit discharge Investigation files are organized by the address/location where the illicit discharge occurred and the Fiscal Year in which they occurred. 15.5. Employee Training is implemented on an annual basis to those employees, who in the course of their normal work day, may come into contact with or observe an illicit discharge. The training is conducted by the Stormwater Coordinator who presents a power point presentation to employees. Training is documented by an attendance roster and kept on file. The presentation includes: 15.5.1. What are Illicit Discharges? Examples and discussion 15.5.2. What non-stormwater discharges are allowable? Examples and discussion 15.5.3.

Prevent or Minimize Contamination of Stormwater Runoff From All Areas used for Vehicle and Equipment Cleaning: The City of Belmont does not currently own or operate a covered vehicle wash bay with an oil/water separator connected to the sanitary sewer system. However there is a project for a dedicated wash bay to be installed at Public Works on the Capital Improvements Project List. Vehicle and Equipment cleaning is covered in the SWPPP Section V and includes guidelines and practices to prevent or minimize contamination of stormwater runoff from areas used for Vehicle and Equipment Washing. The Sludge Transfer Station at the Wastewater Treatment Plant is a designated area for municipally -owned vehicles and equipment. This area is on an asphalt drive with a drop inlet drain that is connected to the influent of the plant so that wash water drains to the headworks and goes through the wastewater treatment plant. Use of biodegradable phosphate -free wash detergent is required. A second designated wash area is located at the rear of Public Works on a gravel area that sheet flows to the surrounding vegetated area where wash water is absorbed by the vegetation and soil. Use of biodegradable phosphate -free wash detergent is required. 18.11. Waste Disposal: The City has and will continue to dispose of waste removed from the MS4 and other municipal operations, including accumulated sediments, floatables, and other debris at a certified landfill in accordance with the regulations governing the disposal facility. 18.12. Flood Management Projects: There are no existing or proposed flood plain management projects. Should one be proposed in the future, particularly to facilitate the development of property, the City will review the project through its current project/plan review procedures. This process involves the Planning Department, Public Works Department and Engineering Department. 18.13. Decision Process: The pollution prevention/good housekeeping program was developed in cooperation with the City's Administrative, Public Works, and Planning Departments and measurable goals established. Appropriate staff was designated as the responsible person for each BMP. 18.14. Evaluation: The pollution prevention program is evaluated annually during the preparation of the annual compliance report. The Stormwater Coordinator evaluates the effectiveness of the program and recommends modifications and improvements to the Public Works Director. The BMP measurable goals are indicated in the BMP summary. CITY OF BELMONT 35 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 19. Practices to Inspect and Maintain Structural Stormwater Control Devices: The City of Belmont owns three structural stormwater control measures (SCMs), however none of the SCMs were required for water quality or treatment purposes per the City's Watershed Protection Ordinance or the adopted Gaston County Stormwater Ordinance. Gantt Soccer Park — approximately 1760 SQFT of Permeable Interlocking Concrete Pavers (PICP) make up 10 parking spaces in the parking lot. Kevin Loftin Riverfront Park — approximately 1005 SQFT of Permeable Interlocking Concrete Pavers (PICP) at the parking lot entrance round -a -bout. Also at this site is a 0.8' x 1.5' x 70' Concrete Level Spreader which drains the PICP, Parking Lot, and portions of surrounding Open Spaces. O&Ms have been developed for each of the structural stormwater controls and they are located in the Streets & Stormwater System Operation & Maintenance Manual (SSSOMM). The O&Ms include inspection schedules and maintenance procedures for each of the SCMs. 20. Practices to Reduce Polluted Stormwater Runoff from Municipally -Owned Streets, Roads, and Public Parking Lots, Storm Drains/Catch Basins/Drainage Structures, Manholes, Piped and Vegetative Conveyances: The City of Belmont has developed a Streets & Stormwater System Operation and Maintenance Manual (SSSOMM) to outline practices that work to reduce polluted stormwater runoff from municipally owned Streets, Roads, Public Parking Lots, storm drains and drainage structures, piped and vegetative conveyances, and storm sewer manholes. 20.1. Streets, Roads, and Public Parking Lots: The City currently has a street sweeping program that helps to reduce floatable materials and other pollutants from reaching the MS4. City Streets, as well as several NCDOT roads, are separated into routes for the Street Sweeper Operator to work in. The Recommended Schedule for sweeping City Streets is list as well but adherence to schedule is heavily based on the Stormwater Department's work schedule. Street Sweeper maintenance down -time is also a determining factor in the sweeping schedule. The City also has a list of Priority Streets comprised of major thorough fares and areas historically prone to flooding, that are kept clean whether by running the street sweeper or by manually cleaning off storm drain tops with shovels. Public parking lots and City Facility parking lots are to be swept on a quarterly and/or as needed basis. 20.2. Storm Drains/Catch Basins/Drainage Structures: Storm drains, catch basins, and/or drainage structures are to be inspected annually for build-up of sediments, debris, trash, vegetation, structural condition, etc. If SD/CB is one-third to one-half full from the invert of pipe to the top of the grate, then it requires cleaning. If SD/CB is more than one-half full then it should be cleaned more frequently. If the structural condition requires maintenance, CITY OF BELMONT 36 STORMWATER MANAGEMENT PROGRAM Permit NCS000409 — 2022-2027 the drainage structure is scheduled for maintenance by city staff or contracted repair. 20.3. Manholes: MS4 manholes are to be inspected annually for build-up of sediments, debris, trash, vegetation, structural condition, etc. If the manhole is one-third to one-half full from the invert of pipe to the top of the grate, then it requires cleaning. If the manhole is more than one-half full then it should be cleaned more frequently. If the structural condition requires maintenance, the manhole is scheduled for maintenance by city staff or contracted repair. 20.4. Piped Conveyances: Piped conveyances are to be inspected annually for build-up of sediments, debris, trash, vegetation, structural condition, etc. If pipe is one-third to one- half full from the invert of pipe to the top of the pipe, then it requires cleaning. If pipe is more than one-half full then it should be cleaned more frequently. If the structural condition requires maintenance, the piped conveyance is scheduled for maintenance by city staff or contracted repair. 20.5. Vegetated Conveyances: Vegetated conveyances are to be inspected annually for build- up of sediments, debris, trash, vegetation, structural condition, etc. If the vegetated conveyance is one-third to one-half full from the invert to the top of the slope, then it requires cleaning. If the vegetative conveyance is more than one-half full then it should be cleaned more frequently. If the vegetated conveyance is eroding or washing out, then it requires maintenance and is put on schedule for maintenance by city staff or contracted repair. 21.
