During the period beginning on the effective date of the permit and lasting until expiration, the City of Gastonia is authorized to discharge stormwater from the municipal separate storm sewer system (MS4) to receiving waters Anthony Creek, Bessemer Branch, Blackwood Creek, Burton Branch, Catawba Creek, Crowders Creek, Duharts Creek, Jule Allen Branch, Kagler Creek, Long Creek, McGill Creek, Oates Creek, Rankin Lake, Robinwood Lake, and unnamed tributaries to them, all within the Catawba River Basin. Such discharge shall be controlled, limited and monitored in accordance with the permittee's Comprehensive Stormwater Management Program Report, herein referred to as the Stormwater Plan. The Stormwater Plan includes components of the permittee's Phase I1 Municipal NPDES Stormwater Permit Application, Comprehensive Stormwater Management Program Report, and any approved modifications. 2. All discharges authorized herein shall be adequately managed in accordance with the terms and conditions of this pen -nit. Any othcr'point source discharge to surface waters of the state is prohibited unless it is an allowable non-stormwater discharge or is covered by another permit, authorization, or approval. 3. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, orllocal law, rule, standard, ordinance, order, judgment, or decree. 4. This permit covers activities associated with the discharge of stormwater from the MS4 within the jurisdictional area of the permittee as described in the approved Stormwater Plan to control potential pollution from the MS4. The permit applies to current and future jurisdictional areas of the I ittee, as well as areas that seek coverage under this permit through inter -local or other similar agreements with the permittee. Agreements for coverage under'this permit must be approved by the Division of Water Quality, herein referred to as the Division. 5. The Division may deny or revoke coverage under this pen -nit for separate entities and may require independent permit coverage as deemed necessary. In addition, the permittee may petition the Division to revoke or deny coverage under this permit for specific entities. 6.

The permittee shall develop and implement its approved Stormwater Plan in accordance with Section 402(p)(3)(B) of the Clean Water Act, provisions outlined by the Director, and the provisions of this permit. 7. The permit requires the development and proper implementation of the Stormwater Plan. The purpose of the Stormwater Plan is to reduce the discharge of pollutants from the MS4 to the maximum extent practicable, to protect water quality, and to satisfy the applicable Part I Page 1 of 2 Pcnnit No. NCS000429 water quality requirements of the Clean. Water Act. Implementation of best management practices consistent with the provisions of the Stormwater Plan constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. Successive iterations of the Stormwater Plan and other components of this permit shall be driven by the objective of assuring that discharges do not cause or contribute to the violation of water quality standards, through the expansion and tailoring of management measures within the scope of the Stormwater Plan. The permit authorizes the point source discharge of stormwater runoff from the MS4. In addition, discharges of non-stormwater are also authorized through the MS4 of the permittee if such discharges are: (a) Permitted by, and in compliance with, another NPDES discharge permit including discharges of process and non -process wastewater, and stormwater associated with industrial activity; or (b) Determined to be incidental non-stormwater flows that do not significantly impact water quality and may include: • water line flushing; • landscape irrigation; • diverted stream flows; • rising groundwaters; • uncontaminated groundwater infiltration; • uncontaminated pumped groundwater; • discharges from potable water sources; • foundation drains; • air conditioning condensate (commercial/residential); • irrigation waters (does not include reclaimed water as described in 15A NCAC 2H .0200); • springs; • water from crawl space pumps; • footing drains; • lawn watering; • residential and charity car washing, • flows from riparian habitats and wetlands; • dechlorinated swimming pool discharges; • street wash water; • flows from emergency fire fighting.
