This SWMP identifies the specific elements and minimum measures that the City of Conover 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 NCS000488, as issued by NCDEQ. This permit covers activities associated with the discharge of stormwater from the MS4 as owned and operated by the City of Conover and located within the corporate limits of the City of Conover. In preparing this SWMP, the City of Conover 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.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Conover has evaluated residential and charity car washing for possible significant water quality impacts. Street cleaning is performed with dry street sweeping process; however construction sites occasionally with clean the streets with potable water as directed by NCDOT and Erosion Control requirements. The Division has not required that other non-stormwater flows be specifically controlled by the City of Conover. Wash water associated with car washing that does not contain detergents/surfactants or does not discharge directly into the MS4 is considered incidental. However, these types of non-stormwater discharges that do contain detergents/surfactants have been evaluated by the City of Conover to determine whether they may significantly impact water quality. The City of Conover will address the possibility of the below mentioned water quality impacts through public education and good housekeeping, as outlined in Part 5 BMP 3-8 and Part 10 BMP 45-47, 49, 52-54, 56, 57 and 61 with focusing on good housekeeping training and practices.

Target pollutants as listed below are contributors of the stream impairment. TMDL measures have been put in place to improve water quality. 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 the target pollutants. In addition, the City of Conover has observed and evaluated: schools, homeowners, businesses, industrial sites, farming, construction activities, and public employees as target audiences that are likely to have significant stormwater impacts. Within the table and list below the following target pollutants have been found to be concerns within the community. Litter: Roadside litter is an ongoing issue for the City. 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/conveyances that lead 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. Most litter is found on the side of major roads, around school facilities, and certain businesses. Sediment: Sediment buildup is largely attributed to mismanaged construction sites with fallen or incorrectly installed sediment fences. Erosion control fences failing or being improperly maintained. This has led to sediment buildup near storm drains, onto down slope private properties, and in some cases causing water to build up in nearby properties as the sediment is limiting the drains ability to remove runoff. In all cases the city has responded and had the issue solved, but even being down for a short time can have significant effects. Erosion control fences are required for sediment control permits during construction by the DEQ throughout the entire construction process. Gray Water: In the past a few residents have been found with washing machines straight -piped out of their homes by using water hoses exiting windows. Homes are to be connected to the appropriate sewer system. This proves to be a source of detergents/soaps entering our storm drains in residential neighborhoods. In addition: 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 waterways via the storm drain system. DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 9 Fats Oils and Grease: Can become an issue when grease traps are not appropriately maintained. This has led to cases of the restaurants allowing the grease to drip onto nearby impermeable surface — 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. In all cases, code enforcement has responded and the issues have been remedied. Chemicals: Industrial sites housing totes/containers of unknown/unmarked chemicals can lead to potential soil and water contamination, and/or incorrect spill cleanup procedure. Totes/containers are to be correctly stored in a way to minimize risk to the water bodies from seepage, damage to the containers, or spills. Any reports Code enforcement has responded. Animal Operations: agricultural runoff often caries excess fertilizer which will cause eutrophication in streams with its cascading effects. Within the Catawba River Basin roughly 46 streams are/were impacted by fecal coliform, with 10 being listed on the 303(d) list. As this is a non -point source pollutant it is hard to locate the exact source of this runoff, however in much of the watershed there is agricultural zoning that makes it likely for these types of impairments to occur. The City does allow Shetland horses (sub 125 lbs. and under 34 inches at shoulder), which has a small potential for increasing nutrient load from horse waste. Underground storage tanks: Storage devices installed below ground can contain gasoline, fuels such as propane, industrial chemicals/oils, and most often human waste (fecal coliform) 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 a 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. Conover has worked with EPA Brownfield Assessment grants prior to determine the level of contamination (if any) from former industrial sites. Some areas of the City still have homes that utilize septic tanks, but the majority of properties in the City are served by sanitary sewer. If a septic tank is leaking, it can overwhelm the natural processes of the soil (infiltration) leading to nutrient overload in streams fed by groundwater, or allowing pathogens to enter, increasing the risk of disease. The 10 303(d) fecal coliform impaired streams listed can have some attribution to septic tank leakage. When septic tank failure is noted, the home is required to connect to sanitary sewer where available. Illicit discharges: Originate from a variety of sources, with an equally varied number of effects dependent on the chemical that is released. Typically, illicit discharges come from businesses, residents or municipal facilities who 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 as we have several 303(d) streams impaired from causes related to substances or attributions given to unclean discharges into the streams - in addition to reports generated by the municipality. Many of the 303(d) benthos impaired streams can be attributed to IDDE issues, but they are often from inexact/non-point sources that are attributed to illicit discharges Illegal dumping: Waste dumped randomly in non -permitted dumping areas, can cause 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 TVs 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 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. The City provides municipal residential solid waste pick-up weekly to all City residents. DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 10 Improper disposal of waste: 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. These types of problems have been noticed by municipal waste managers and can be difficult to track since the improperly disposed waste is mixed in with the standard refuse. Other examples include grease going down sinks clogging sanitary MS4 systems, chemicals from batteries leaching into the groundwater, oil from oil changes not going to the correct facility, etc. While some of the target audiences are not as prominently found within the City, it is still important to educate because they can be likely sources of non -point pollution through uninformed management practices.

The budget includes the permit administration and compliance fee, which is billed by DEQ annually. The City of Conover's Environmental Coordinator/Construction manager's salary one-third is covered by stormwater and two-thirds by water and waste water fees. To help cover support expenses Public Works allocated 180,000 from General Fund and Utility Monies. Leaf collection is complete by City Sanitation Staff and temporary contract workers. During the non -leaf season Grounds oversees the litter sweep, with $21,500 allocated. The City of Conover has a two-year contract (which will need to be modified, adopted, and signed every two years) with Western Piedmont Council of Governments for the following support services: Public Education and Outreach Program, Public Involvement and Participation Program, Illicit Discharge Detection and Elimination Program, Post -Construction Site Runoff Control Program, and Pollution Prevention and Good Housekeeping Programs. The current contract amount for the 2-year period (years 1 and 2 of the NPDES permit cycle) is $53,354.00 of general funds being used. The City will be responsible for the cost of the annual NPDES permit renewal, which is to be paid to the state. Any fees charged to the development community for BMP Inspections, Plan Review, and other associated fees will be used to help offset cost. DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 14 The City may determine that stormwater utility fees should be implemented; these fees would be collected by the City through utility bills. Should the City of Conover choose not to renew the existing two-year contract, prior to the last month, a revision to the existing NPDES permit and Stormwater Management Plan would need to occur. The City of Conover would be required to renew the two-year contract, in years 2022 and 2024, to fully carry out the 5 year NPDES permit cycle. 4.3 Shared Responsibility The City of Conover will be responsibility, with WPCOG (referred to as entity) providing support service, to implement the following minimum control measures, which are as stringent as the corresponding NPDES MS4 Permit requirement. The City of Conover remains responsible for compliance if the other entities fail to perform the permit obligation and both may be subject to enforcement action, if neither the City of Conover, nor the other entities fully perform the permit obligation.

Per BMP 1 the SWMP will be reviewed on an annual basis to determine if any updates need to occur. All documents associated to the Stormwater program will be accessible online, either via the City of Conover website or the Western Piedmont Council of Governments Stormwater Partnership webpage (reference BMP 14 and 30). Documentation of all actions related to stormwater activities (as mentioned below) will be recorded, so staff can track and evaluate the effectiveness of each program component. The City of Conover will manage and report the following Best Management Practices (BMPs) for the administration of the Stormwater Management Program using Public Education & Outreach, Public Involvement & Participation, Illicit Discharge Detection & Elimination, Post -Construction Site Runoff Control, and Pollution Prevention & Good Housekeeping.

The target audiences and identified pollutants listed in Part 3.9 of this SWMP, which will be addressed by the Public Education and Outreach Program, are summarized in Table 12 below. In addition, the City of Conover is required to inform businesses and the general public of the hazards associated with illicit discharges, illegal dumping and improper disposal of waste. The City will take a proactive approach in reporting the amount and to whom is reached through public education and outreach efforts.

The City of Conover's Planning Board will continue to function as the City's stormwater/watershed advisory board. The WPCOG Water Resources Committee will continue to offer a forum for public comment with input and representation from the City of Conover as a way to represent their municipality/citizens in these meetings along with other municipalities. The Boards/Committee will also help provide input and guidance on stormwater issues. The City has a community volunteer program to gain citizen participation to complete stream clean-ups or litter sweeps. The City of Conover has an established hotline (main number for the City Hall), but will now be directed to WPCOG stormwater hotline, as well as, the addition of a webpage reporting form and survey/s, along with the use of the existing WPCOG Water Resource Committee to gather public input. All events, programs, and public forums will be announced through social media and/or printed handouts. The City of Conover will manage, implement, and report on the following public involvement and participation BMPs. Table 14: Public Involvement and Participation BMPs Permit 3.3.1: Public Input Ref.

DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 26 PART 7: ILLICIT DISCHARGE DETECTION AND ELIMINATION PROGRAM Per the MS4 Inspection Report the City has written procedures for implementing an IDDE Program. To increase efforts the City will locate priority areas likely to have illicit discharges, conduct routine dry weather outfall inspections, identify illicit discharges and trace sources, eliminate the source(s) of an illicit discharge, and evaluate and assess the IDDE Program. The City has a stormwater ordinance and other regulatory mechanisms that provide the legal authority to prohibit illicit connections and discharges to the MS4, as well as the authority to apply enforcement to violators of the ordinance. The documents will be reviewed, and if necessary, updated to maintain the program and enforce IDDE issues effectively. The City of Conover has approximately half of the MS4 mapping completed; however as development occurs the map and associated components will be updated accordingly. In the last permit cycle the City did not conduct dry weather screening or maintain written procedures for dry weather field activity (II.D.2.d. Dry Weather Flow Program). Within the Stormwater Management Plan a schedule is to be created to conduct dry weather screening annually. Data such as date screening occurred, location of inspected outfall, and photos of outfall will be recorded in GIS. The City of Conover in the past has investigated IDDE complaints; however there is no tracking mechanism for documenting violations and enforcement actions (II.D.2.j.). Within the new permit cycle, the use of a GIS application to track and document IDDE cases will be used. This will allow the City to identify priority areas based on historical data. Further, the City will continue to train municipal staff and the general public to identify illicit discharges and illegal dumping through the use of educational outreach materials and training opportunities. Educational material will be available to help educate public employees, businesses, and the general public about hazards associated with illicit discharges and the improper disposal of waste. Public complaints of any kind could be submitted to the City through point contact on the webpage. A webpage portal will be established on the WPCOG website, as well as, linked to on the City website. The portal will be publicized, as well as, the stormwater hotline phone number, as mentioned in the public education and outreach and public involvement sections of this plan. A citizen can make a complaint via hotline number or through an email tool on the WPCOG webpage. The City of Conover will develop, manage, implement, document, report, and enforce an Illicit Discharge Detection and Elimination Program which shall, at a minimum, include the following illicit discharge detection and elimination BMPs. The existing Illicit Discharge Detection and Elimination Program will be expanded in order to implement a complete program by permit year 5.

DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 39 PART 9: POST -CONSTRUCTION SITE RUNOFF CONTROL PROGRAM The City of Conover SWMP 2013 has policy language for deed restrictions and protective covenants. In the new SWMP permit cycle the language will also be included in the Stormwater Ordinance. An amendment to the ordinance will allow the language to have legal significance. Contracting WPCOG, an inventory of projects will be established (BMP 35.B.1, 2, and 3) for developments within the municipal limits, this is in response to Permit Citation II.F.2.d, of the latest DEQ MS4 audit (2018). Along with the inventory list, proactive inspections will be administered by Staff semi-annually and the owner of the privately owned SCM will be required to have an inspection done by a certified private engineer annually to ensure SCM functionality (Permit Citation II.F.2.g.). Upon non-compliance, enforcement action will be taken. The City will have a GIS tracking mechanism to proactively enforce to obtain compliance (II.F.2.i.). 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 City of Conover 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. In accordance with 15A NCAC 02H .0153 and .1017, the City of Conover implements the following State post - construction program requirements, which satisfy the NPDES Phase II MS4 post -construction site runoff control requirements as Qualifying Alternative Program(s) (QAPs) in the MS4 area(s) where they are implemented.

DRAFT NCS000431 SWMP City of Conover February 23, 2020 Page 49 PART 10: POLLUTION PREVENTION AND GOOD HOUSEKEEPING PROGRAMS This SWMP provides a comprehensive pollution prevention and good housekeeping strategy for the City of Conover municipal facilities and operations. Pollution prevention and good housekeeping is accomplished through the implementation of seven required programs, which collectively address the ultimate goal of preventing or reducing pollutant runoff from municipal operations such as park and open space maintenance, fleet and building maintenance, new construction and land disturbances, and municipal storm sewer system maintenance. Pollution prevention and good housekeeping for municipal operations includes the following programs: 1. Municipal Facilities Operation and Maintenance Program (O & M) 2. Spill Response Program 3. MS4 Operation and Maintenance Program 4. Municipal SCM Operation and Maintenance Program 5. Pesticide, Herbicide and Fertilizer Management Program 6. Vehicle and Equipment Cleaning Program 7. Pavement Management Program The City of Conover will manage, implement and report the pollution prevention and good housekeeping BMPs as specified in Table 21 below for each required program in response for the MS4 Audit inefficiencies. BMPs 45 and 46 will require a written inventory of facilities and potential pollutants. Several of the BMPs below address street and parking lot issues by developing, adopting, and maintaining procedures that focus on pollutant removal in these impervious areas, along with, Setting schedules and requirements for street/parking lot sweeping (BMP 58), collecting litter/debris (BMP 59), working in collaboration with community outreach program and developing standard spill procedures (BMP 47). The City of Conover uses a vac -truck to clean the storm sewer conveyance system. An O & M plan had not been created and maintained at the time of the MS4 DEQ Audit. Permit Reference: 3.7.3, BMP's 48-51 focus on the training, inspection, and maintenance of said system. Table 21: Pollution Prevention and Good Housekeeping BMPs Permit 3.7.1: Municipal Facilities Operation and Maintenance Program Ref. Measures to manage facilities that are owned and operated by the permittee and have the potential for generating polluted stormwater runoff. The permittee shall maintain a current inventory of municipal facilities; perform facility inspections and routine maintenance; establish specific frequencies, schedules, and standard documentation; provide staff training on general stormwater awareness and implementing pollution prevention and good housekeeping practices.
