Such discharge will be controlled, limited and monitored in accordance with the permittee's Stormwater Quality Management Program, herein referred to as the Stormwater Plan. The Stormwater Plan shall detail the permittee's stormwater management program for the five-year term of the stormwater permit including, for each of the measures identified in the permit, a narrative description of the program, a table that identifies each best management practice (BMP) used, the frequency of the BMP, the measurable goals for each BMP, the implementation schedule, funding and the responsible person or position for implementation. 2. All discharges authorized herein shall be managed in accordance with the terms and conditions of this permit. Any 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. This permit does not relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree. 4. This permit covers activities associated with the discharge of stormwater from the MS4 owned and operated by the permittee within the jurisdictional area of the permittee. The permit applies to jurisdictional areas of the permittee, as well as areas that seek coverage under this permit through inter -local or other similar agreements with permittee. Agreements for coverage under this permit shall be approved by the Division of Energy, Mineral, and land Resources, herein referred to as the Division. The Division may deny or revoke coverage under this permit for separate entities and 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 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. The specific requirements of section 402(p)(3)(B) of the Clean Water Act require that the permittee effectively prohibit non-stormwater discharges to the permittec's MS4 and that controls and management measures are implemented by the permittee to reduce the discharge of pollutants from the municipal stone sewer system to the maximum extent practicable. The purpose of the Stormwater Plan is the means by which the permittee will describe how it is in compliance with the permit. Compliance with the six minimum measures in 40 CFR § 122.34(b) and the additional provisions of Session Law 2006-246 constitute compliance with the requirements of this permit, the Clean Water Act and Session Law 2006-246 to reduce the discharge of pollutants from the MS4 to the maximum extent practicable, to protect water quality, and to satisfy the applicable water quality requirements of the Clean Water Act. Implementation of best management practices consistent with the provisions of the Stonnwater Plan constitutes compliance with the standard of reducing pollutants to the maximum extent practicable. Part I Page 1 of 2 PERMIT NO. NCS000584 9. 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 permit, authorization, or approval, 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 and fire hydrant flushing; • landscape irrigation; • diverted stream flows; • rising groundwaters; • uncontaminated groundwater infiltration; • uncontaminated pumped groundwater; • discharges from uncontaminated potable water sources; • foundation drains; • air conditioning condensate (commercial/residential); • irrigation waters; • 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.

The permittee should use U.S. EPA's website resources to identify the initial recipient for electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities (initial recipient) means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)). As of permit issuance, The NC DEQ anticipates that EPA will be the initial recipient for electronic MS4 Program Reports. EPA plans to establish a website that will also link to the appropriate electronic reporting too] for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Currently, Electronic Reporting Rule information is found at: httpsa/www.e]2a.gov/compliance/final-national-pollutant-discharge- elimination-system-npdes-electronic-reporting-rule Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.

A single storm event may contain up to 10 consecutive hours of no precipitation. For example, if it rains for 2 hours without producing any collectable discharge, and then stops, a sample may be collected if a rain producing a discharge begins again within the next 10 hours. 23. Storm Sewer System Is a conveyance or system of conveyances which are designed or used to collect or convey stormwater runoff that is not part of a combined sewer system or treatment works. This can include, but is not limited to, streets, catch basins, curbs, gutters, ditches, man-made channels or storm drains that convey stormwater runoff. 24.

Stormwater Management Program (SWMP) The term Stormwater Management Program (SWMP) refers to the stormwater management program that is required by the Phase I and Phase II regulations to be developed by MS4 permittees. 26. Stormwater Plan The Stormwater Plan is the written plan that is used to describe the various control measures and activities the permitlee will undertake to implement the stormwater management program. The Stormwater Plan is a consolidation of all of the permittee's relevant ordinances or other regulatory requirements, the description of all programs and procedures (including standard forms to be used for reports and inspections) that will be implemented and enforced to comply with the permit and to document the selection, design, and installation of all stormwater control measures. Part Vlll Page 5 of 6 PERMIT NO. NCS000584 27, Stormwater Runoff The flow of water which results from precipitation and which occurs immediately following rainfall or as a result of snowmelt. 28. Total Maximum Daily Load (TMDL) A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed water quality assessment that provides the scientific foundation for an implementation plan. The implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to restore and maintain water quality standards in all seasons. The Clean Water Act, Section 303, establishes the water quality standards and TMDL programs. Part VIII Page 6 of 6
