Need to Halt or Reduce not a Defense PART J DEFINITIONS U Permit No. NCG190000 PART A: NCGO19 PERMIT COVERAGE All persons desiring to have facilities covered by this General Permit must register with the Division of Energy, Mineral, and Land Resources (the Division) by filing a Notice of Intent (NOI) and paying the applicable fees. The NOI shall be submitted and a Certificate of Coverage (COC) issued prior to any discharge of stormwater associated with industrial activity that has a point source discharge to the surface waters of the state or to a separate storm sewer system conveying discharges to surface waters. This General Permit is applicable to establishments primarily engaged in: operating marinas including activities such as renting boat slips, storing boats, and generally performing other services including cleaning and incidental boat repair; and ship and boat building and repairing. This permit also includes stormwater runoff from vehicle maintenance areas. Marinas where vehicle maintenance, equipment cleaning, fueling, painting, or maintenance/repair are not conducted are not subject to this permit. Any owner or operator not wishing to be covered or limited by this General Permit may make application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the reasons supporting the request. Any application for an individual permit shall be made at least 180 days prior to commencement of discharge. This General Permit does not cover activities or discharges covered by an individual NPDES permit until the individual permit has expired or has been revoked. Any person conducting an activity covered by an individual permit but which could be covered by this General Permit may request that the individual permit be revoked and coverage under this General Permit be provided. If industrial materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion from permitting must submit a No Exposure Certification NOI form to the Division; must receive approval from the Division; must maintain no exposure conditions unless authorized to discharge under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually. Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load (TMDL) for pollutants for stormwater discharges is established. A TMDL sets one or more pollutant -loading limit(s) that affect(s) a watershed, or portion of a watershed, draining to an impaired water. To not be subject to the TMDL, each facility with one or more discharges to watersheds affected by a TMDL must demonstrate it does not have reasonable potential to violate applicable water quality standards for those pollutants identified in the TMDL as a result of discharges. If the Division determines that discharges have reasonable potential to cause water quality standard violations, the facility shall apply for an individual permit 180 days prior to the expiration date of this General Permit. After that individual permit becomes effective, the facility will no longer have coverage under this General Permit. Note the permiee must identify impaired waters in the General Location Map, as outlined in the Stormwater Pollution Prevention Plan (SWPPP), Part B of this permit. A list of approved TMDLs for the state of North Carolina can be found at https://deq,.nc.gov/about/divisions/water-resources/planning/modeliug-- Page 1 of 37 Permit No. NCG190000 assessment/tmdls. Until this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater to the surface waters of North Carolina or a separate storm sewer system which has been treated and managed in accordance with the terms and conditions of this General Permit and the requirements of the permittee's COC. The permittee's COC is hereby incorporated by reference into this General Permit. Any violation of the COC is a violation of this General Permit and subject to enforcement action as provided in the General Permit. Any other 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. The discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality Standards. Discharges allowed by this permit must meet applicable wetland standards as outlined in 15A NCAC 213.0230 and .0231 and water quality certification requirements as outlined in 15A NCAC 21-1.0500. If marina or other activities (covered by this permit) expand or change after issuance of the COC such that the types of discharges are affected, the permittee must first contact the Division to determine if modifications to the COC are necessary. This permit does not relieve the permittee's responsibility for compliance with any other applicable federal, state, or local law, rule, standard, ordinance, order, or decree.
