NPDES Wastewater All wastewater discharges to surface waters in the State of North Carolina must receive a permit to control water pollution. The Clean Water Act of 1972 initiated strict control of wastewater discharges with the responsibility of enforcement given to the Environmental Protection Agency (EPA). The EPA then created the National Pollutant Discharge Elimination System (NPDES) to track and control point sources of pollution. The primary method of control is by issuing permits to dischargers with limitations on wastewater flow and constituents. The EPA delegated permitting authority to the State of North Carolina in 1975. The NPDES program at the Division of Water Resources is responsible for the issuance of wastewater discharge permits. This process includes determining the quality and quantity of treated wastewater that the receiving stream can assimilate, incorporating input from stream modeling, collaborating with Regional Office staff , and evaluation of the discharger’s location. The NPDES program is managed by three units in the permitting section, the Industrial Permitting Branch, the Municipal Permitting Branch, and the Compliance and Expedited Permitting Branch. Where appropriate, the NPDES program establishes limits for flow (quantity discharged), conventional pollutants (BOD, pH, TSS, fecal coliform, oil & grease, etc.), toxicants (metals, volatile organics, etc.), and non-conventional pollutants such as ammonia and nutrients. Delegated states have the authority to establish state water quality standards which can be more stringent than federal standards established by EPA. For more information about the applications process, links to our applications, and other types of forms, please visit the NPDES Permitting Process page. In addition to administering the NPDES program in North Carolina, there is also the responsibility of enforcement of the discharge limitations through our NPDES Compliance program. Please visit the NPDES Compliance webpage for more information and to access Compliance-related forms. Please note that the penalty for discharging without a permit is a fine of up to $25,000 per day.
