This SWMP identifies the specific elements and minimum measures that the Town of Laurel Park will develop, implement, enforce, evaluate, and report to the North Carolina Department of Environmental Quality(NCDEQ)Division of Energy,Minerals and Land Resources(DEMLR) in order to comply with the MS4 Permit number NCS000478, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the Town of Laurel Park and located within the corporate limits of the Town of Laurel Park. In preparing this SWMP,the Town of Laurel Park has evaluated its MS4 and the permit requirements to develop a comprehensive 5-year SWMP that will meet the community's needs, address local water quality issues, and provide the minimum measures necessary to comply with the permit. The SWMP will be evaluated and updated annually to ensure that the elements and minimum measures it contains continue to adequately provide for permit compliance and the community's needs. Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP,along with any approved modifications of the SWMP,are incorporated by reference into the permit and become enforceable parts of the permit. Any major changes to the approved SWMP will require resubmittal, review,and approval by NCDEW, and may require a new public comment period depending on the nature of the changes.

NCS000478 SWMP Town of Laurel Park January 31,2023 Page 7 Table 5: NPDES Stormwater Permitted Industrial Facilities Permit Number Facility Name N/A N/A 3.8 Non-Stormwater Discharges The water quality impacts of non-stormwater discharges have been evaluated by the Town of Laurel Park as summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The Town of Laurel Park has evaluated residential and charity car washing and street washing for possible significant water quality impacts. Street washing discharges are addressed under the Pavement Management Program in Part 10 of this SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the Town of Laurel Park. Wash water associated with car washing that does not contain detergents or does not discharge directly into the MS4 is considered incidental. However, these types of non-stormwater discharges that do contain detergents have been evaluated by the Town of Laurel Park to determine whether they may significantly impact water quality. The Town of Laurel Park will address the possibility of the below mentioned water quality impacts through public education and good housekeeping, as outlined in Part 5 and Part with a focus on the training of good housekeeping practices. Table 6: Non-Stormwater Discharges Non-StormwaterDischarge Water Quality Impacts Waterline and fire hydrant flushing Incidental Landscape irrigation Incidental Diverted stream flows Incidental Rising groundwater Incidental Uncontaminated groundwater infiltration Incidental Uncontaminated pumped groundwater Incidental Uncontaminated potable water sources Incidental Foundation drains Incidental Air conditioning condensate Incidental Irrigation waters Incidental Springs Incidental Water from crawls ace pumps Incidental Footing drains Incidental Lawn watering Incidental Residential and charity car washing Possible Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Possible Flows from firefighting activities Incidental NCS000478 SWMP Town of Laurel Park January 31,2023 Page 8 3.9 Target Pollutants and Sources In addition to those target pollutants identified above,the Town of Laurel Park is not aware of other significant water quality issues within the permitted MS4 area. Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP,the likely activities/sources/targeted audiences attributed to each pollutant and identifies the associated SWMP program(s)that address each. In addition,the Town of Laurel Park has evaluated schools, homeowners, and businesses as target audiences that are likely to have significant stormwater impacts. Some target pollutants and sources pose a greater threat to water quality than others. For example,the Town of Laurel Park does not have many charitable car wash events,therefore, gray water runoff is not as pertinent of an issue. However, sediment runoff from construction sites is a more common issue facing the Town.Further differences in the threat level of types of target pollutants are discussed below. Litter: Illegal dumping has occurred and been noted by code enforcement officers within the Town. Cases of both illegal construction waste dumping and general residential or school dumping have been noted by code enforcement officers. This litter poses a threat to both our water bodies and the MS4 infrastructure,as the litter can create clogs and backups that damage the pipelines leading back to the stream. Some litter even poses a threat to groundwater if chemical leaching or breakdown of components into heavy metals occurs due to weathering of the litter.The dumping has been found typically roadside but also in secluded urban areas. Illegal dumping cases are rare in the Town of Laurel Park and poses a minimal threat in comparison to other pollutant sources. Sediment: Previously installed erosion control measure has been removed or fallen Sediment buildup is largely attributed to mismanaged construction sites with fallen or incorrectly installed sediment fences.It has been noticed in both reports from citizens and by code enforcement officers that there are several cases of construction sites not maintaining their erosion control fences during work.This has led to sediment buildup near storm drains, onto downslope private properties,and in some cases causing water to buildup in nearby properties as the sediment is limiting the drain's ability to remove runoff. In all cases,code enforcement has responded and had the issue solved,but even being down for a short time can prove to have significant effects. Erosion control fences are required for sediment control permits during construction by the DEQ throughout the entire construction process. Sediment from construction sites is the most pertinent threat to water quality in Laurel Park.The Town of Laurel Park works with Henderson County to monitor construction sites to minimize the amount of erosion. Gray Water: Residential,Charity, and Municipal Car Washes Residential,charity,and municipal car washes allow for soaps or waxes to enter the storm drain when vehicles are not being cleaned in the correct areas(such as vegetated patches or in areas that do not have storm drains). This allows for toxic contaminants to enter our waterways via the storm drain system. There are very few cases of residential,charity or municipal car washes in the Town.Therefore,this is an NCS000478 SWMP Town of Laurel Park January 31,2023 Page 9 unlikely source of pollution.However,education and information are provided to residents about how to safely conduct car washes to reduce gray water. Fats Oils and Grease: Health Department has noted cases where restaurants do not empty or own/rent grease traps for appropriate removal. The Health Department has reported restaurants in Laurel Park not maintaining grease traps.This has led to cases of the restaurants allowing the grease to drip onto nearby impermeable surfaces—which would eventually lead to water quality issues. Overflow from a lack of maintenance or throwing out the grease with general waste contributes to this problem. This is a health violation since the grease poses a physical risk,but it also can impair water bodies with an influx of water-insoluble grease going down the storm drain.There are very few restaurants in the Town for this to be an issue.Town Code Enforcement and Henderson County Health Department do monitor the restaurants,but there are few cases. For this reason, fats, oils, and grease are a lower threat to water quality. Underground storage tanks: Storage devices installed below ground that contain hazardous materials/waste. These tanks can contain gasoline, fuels such as propane, industrial chemicals/oils,and most often human waste in areas not directly connected to the sanitary sewer. Any underground storage tank must be well maintained/monitored, and correctly installed due to the risk of them leaking. The leaks can cause whatever chemical the tank is storing to leak into the ground, harming the soil,groundwater/water table, and even surface waters as they are being fed from groundwater. If fuel or industrial chemical tank is leaking,the chemical will leach into the soil—leading to toxic soil,contaminated groundwater,and possibly impairing a stream/water body. The Town takes this potential threat seriously and will monitor underground storage tanks. Illicit discharges: Originate from a variety of sources,with an equally varied number of effects depending on the chemical that is released. Typically, illicit discharges come from businesses, residents, or municipal facilities that dump chemicals into storm drains either incidentally due to a lack of IDDE education or general carelessness.These chemicals can vary greatly and can include grease,oils, chemicals,cleaning solutions,paints,metals, etc. This is a recognized problem and regular inspections,and education of Town staff is used to minimize IDDE in Laurel Park. As mentioned, there are no 303(d) streams from causes related to substances or attributions given to unclean discharges into the streams; however,this is an issue the Town continually monitors if a problem does occur. Illegal dumping: When residents,businesses,or municipal employees dump waste randomly in non-permitted dumping areas. This waste can widely vary,causing a variety of problems. For example,citizens dumping televisions on the side of the road to avoid dumping fees, which allows for the metals or chemicals inside the tv to leach out as stormwater passes it(mercury, lead, and other metals). It can be a case of businesses dumping waste in watershed areas where runoff passes through the waste,either carrying it or residuals of the waste into water bodies. It can also be a case of graders dumping sediment into areas without the correct NCS000478 SWMP Town of Laurel Park January 31,2023 Page 10 allowances/precautions. The debris and chemicals accumulate over time and lead to chemical impairments,pH issues,turbidity impairments, or debris entering the stream/MS4 system. Improper disposal of waste: Improper disposal of waste is problematic because it allows chemicals,or difficult to manage waste,to enter the environment in ways that may be hard to track. For example, not giving a car battery to the correct waste management facility can allow for battery acid and lead to enter the soil which drains/collects in the groundwater. This problem has been noticed by municipal waste managers and is difficult to track as often the improper disposal waste is mixed in with the standard refuse. Other examples include grease going down sinks clogging MS4 systems, chemicals from batteries leaching into the groundwater, oil from oil changes not going to the correct facility, etc. Henderson County provides a facility where residents can properly dispose of materials.

The budget includes the permit administering and compliance fee, which is billed by the Division annually. The town provides $3,000.00 in direct funds for stormwater management activities. Additionally,there is approximately$70,000.00 annually for capital projects related to stormwater and stormwater drainage. Any fees charged to the development community for BMP Inspections,Plan Review and other associated fees will help offset the cost.The Town implemented a$5 monthly stormwater fee that is collected by the Town through utility bills.The goal for the funds collected is to support the stormwater program through mapping outfalls, stream repairs, and other water quality efforts. 4.3 Shared Responsibility The Town of Laurel Park will share the responsibility to implement the following minimum control measures,which are at least as stringent as the corresponding NPDES MS4 Permit requirement. The Town of Laurel Park remains responsible for compliance if the other entity fails to perform the permit obligation and may be subject to enforcement action if neither the Town of Laurel Park nor the other entity fully performs the permit obligation. Table 9 below summarizes who will be implementing the component,what the component program is called,the specific SWMP BMP or permit requirement that is being met by the shared responsibility,and whether a legal agreement to share responsibility is in place.

NCS000478 SWMP Town of Laurel Park January 31,2023 Page 27 PART 9: POST-CONSTRUCTION SITE RUNOFF CONTROL PROGRAM This SWMP identifies the minimum elements to develop, implement and enforce a program to address stormwater runoff from new development and redevelopment projects that disturb greater than or equal to one acre,including projects less than one acre that are part of a larger common plan of development or sale,that are located within the Town of Laurel Park and discharge into the MS4. These elements are designed to minimize water quality impacts utilizing a combination of structural Stormwater Control Measures(SCMs)and/or non-structural BMPs appropriate for the community and ensure adequate long- term operation and maintenance of SCMs. All Post-Construction management is done through an agreement with Henderson County which maintains and enforces a checklist to ensure projects meet all standards. In accordance with 15A NCAC 02H .0153 and.1017,the Town of Laurel Park implements the following State post-construction program requirements,which satisfy the NPDES Phase II MS4 post-construction site runoff control requirements as Qualifying Alternative Programs(QAPs) in the MS4 area(s)where they are implemented. Laurel Park has two non-conflicting codes that address post-construction stormwater. In the Town Code of Ordinances,Chapter 53 outlines the Town's stormwater management policies. Additionally,there is a separate stormwater ordinance which is referenced in Table 19.
