Permits Issued by the Mid-Atlantic Region

Industrial Wastewater discharges result from water use in industrial/manufacturing operations or from municipal/domestic/household sewage collection and treatment. Wastewater discharges also include discharges from vessels, silvicultural activities, concentrated aquatic animal production facilities and aquaculture projects.

NPDES permits are issued for these direct dischargers of wastewater by EPA Region 3 States, with the exception of the District of Columbia and Federal facilities in Delaware where EPA Region 3 is the permitting authority.

NPDES PERMITS IN THE DISTRICT OF COLUMBIA & DELAWARE

Because the authority to implement the NPDES program has not been delegated to the District of Columbia (DC), EPA Region 3 remains the permitting authority for DC and is responsible for permit issuance.
