This SWMP identifies the specific elements and minimum measures that the City of Concord 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 NCS000423, 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 Concord and located within the corporate limits of the City of Concord. In preparing this SWMP,the City of Concord 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 NCDEQ, and may require a new public comment period depending on the nature of the changes.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Concord evaluated residential and charity car washing for possible significant water quality impacts. It has been determined that wash water from these activities does not significantly impact stormwater quality, as long as they do not become regular,routine occurrences. Stormwater quality issues associated with vehicle washing are addressed in the Public Education and Outreach program. Table 6: Non-Stormwater Discharges Non-Stormwater Discharge Water Quality Impacts Water line 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 Incidental Flows from riparian habitats and wetlands Incidental Dechlorinated swimming pool discharges Incidental Street wash water Incidental Flows from firefighting activities Incidental 3.9 Target Pollutants and Sources In addition to those target pollutants identified above,the City of Concord 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 City of Concord has evaluated schools, homeowners, and businesses as target audiences that are likely to have significant stormwater impacts. Schools provide the platform for educational and involvement opportunities to create stormwater pollution awareness early on. Homeowners,as part of the general public, and businesses were also evaluated as target audiences due to their likelihood of being responsible for non-point source pollution. Each of these target audiences are likely to negatively impact stormwater quality through litter,pet waste, yard waste, and illicit discharges.

The budget includes the permit administering and compliance fee,which is billed by the Division annually. The annual program funding and budgeting of the City's Stormwater Section within the Water Resources NCS000423 SWMP City of Concord April 2024 Page 11 Department is based on revenue projections from stormwater utility service charges/fees that are assessed to and collected from customers located within the existing Concord City limits. Establishment of Stormwater Utility As noted in Section 60-20 of the City Code of Ordinances,the stormwater utility(enterprise fund)was established to support management programs in order to protect water quality by controlling the level of pollutants in and the quantity and flow of stormwater,as well as stormwater structures and natural stormwater drainage systems. In addition,the city manages a Capital Improvement Program(CIP)within the Stormwater Section of the Water Resources Department in an effort to plan for future projects as part of the City's stormwater management system. Basis for Stormwater Utility Service Charges/Fees As noted in Section 60-21 of the City Code of Ordinances, collected stormwater utility service charges/fees are solely used by the department for funding the operational costs,maintenance costs, management costs,indirect costs,capital improvements, debt principal and debt service payments,and establishment of a reserve fund for stormwater services. In recent years,the annual Stormwater Section budget ranged between$5,000,000 and$7,000,000,with approximately$2,000,000 being allocated to fund Stormwater Section Capital Improvement Program(CIP)projects.As noted in the Stormwater Services section of the City's FY 2020-2021 Fees,Rates and Charges Schedule,the current monthly stormwater equivalent runoff unit(ERU)rate is $5.16/ERU. This particular rate is projected to be the same within the City's FY 2021-2022 Fees,Rates and Charges Schedule. Similarly,residential homes are charged as follows: Single-Family Residential Lot Percentage of ERU Amount Added to Total Impervious Surfaces (1 ERU=3,120 sq.ft.) Utility Bill Small(401 to 1,899 sq. ft.) 0.6(60%) $3.10 Medium(1,890 to 5,507 sq. ft.) 1.0(100%) $5.16 Large(Greater than 5,507 sq. ft.) 1.8 (180%) $9.29 Table 1. Breakdown of the City of Concord stormwater residential home fee. Currently,there is a total of 21.26 full-time equivalent(FTE) staff within the City's Stormwater Section for providing the following services: A. Program administration. B. Response to customer service inquiries related to drainage and stormwater quality. C. Drainage system maintenance within City maintained street rights-of-way. D. Compliance with the City's NPDES Phase II Stormwater Permit. E. Review of development plans to ensure compliance with City ordinances. F. Capital engineering and planning. G. Inspections and enforcement of stormwater infrastructure. Stormwater Section 5-Year Capital Improvements Program(CIP)Planning,Funding and Budgeting The City of Concord's 5-Year Stormwater Section CIP planning documents are refined and include a list of future capital projects that have mainly been identified in a completed master plan report,long range and facility studies,or similar planning documents. These projects are included in the 5-Year CIP listing in order to provide satisfactory services to the community,as well as meet future needs,goals and policies of the NCS000423 SWMP City of Concord April 2024 Page 12 City.Other planning documents within the CIP include project descriptions and corresponding justifications/impacts,status(i.e.new,revised,returning),priority numbers,as well as projected project costs for each of the planned phases(i.e.preliminary design,final design,environmental assessment,easement or right-of-way acquisition,construction).In addition,cost estimates and corresponding budgets are completed and/or revised on all 5-Year CIP projects on an annual basis,and include all costs associated with the engineering,environmental assessment,easement or right-of-way acquisition,and construction phases. 4.3 Shared Responsibility The City of Concord 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 City of Concord remains responsible for compliance if the other entity fails to fulfil the permit obligation and may be subject to enforcement action if neither the City of Concord 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.
