This SWMP identifies the specific elements and minimum measures that the City of Hickory 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 NCS000426, 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 Hickory and located within the corporate limits of the City of Hickory. In preparing this SWMP, the City of Hickory 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.MS4 mapping also includes outfalls, flow direction, culverts, ditches, catch basins, manholes and inlets. We are currently working on identifying all major outfalls. The area mapped is 90% but the criteria for major outfalls indicates only 12. Table 1: Summary of MS4 Mapping Percent of MS4 Area Mapped 90.0 % No. of Major Outfalls* Mapped 12 total *An outfall is a point where the MS4 discharges from a pipe or other conveyance (e.g. a ditch) directly into surface waters. Major outfalls are required to be mapped to meet permit requirements. A major outfall is a 36-inch diameter pipe or discharge from a drainage area > 50-acres; and for industrial zoned areas a 12-inch diameter pipe or a drainage area > 2-acres. 3.3 Receiving Waters The City of Hickory MS4 is located within the Catawba River Basin and discharges directly into receiving waters as listed in Table 2 below.

Consultation under Section 7(a)(2) of the ESA is not required for Candidate or Proposed species; although a Conference, as described under Section 7(a)(4) of the ESA is recommended for actions affecting species proposed for listing. FSC=Federal Species of Concern. FSC is an informal term. It is not defined in the federal Endangered Species Act. In North Carolina, the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service) define Federal Species of Concern as those species that appear to be in decline or otherwise in need of conservation and are under consideration for listing or for which there is insufficient information to support listing at this time. Subsumed under the term "FSC" are all species petitioned by outside parties and other selected focal species identified in Service strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists.

Taxa listed as T(S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. See below. EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental, nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land.

The unpermitted non-stormwater flows listed as incidental do not significantly impact water quality. The City of Hickory 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 City of Hickory. 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 City of Hickory to determine whether they may significantly impact water quality. The City of Hickory has found residential non-stormwater discharges to be incidental and business to be incidental. Businesses are required to place water with detergents into a septic system (drain).

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. In addition, the City of Hickory has evaluated schools, homeowners and businesses as target audiences that are likely to have significant stormwater impacts. The City of Hickory has found listed in the table below target pollutants and sources. These pollutants have been concerns within the community, and through public outreach and education the Stormwater program will continue to monitor and minimize.
