An NPDES/SDS Permit is a document that establishes the terms and conditions that must be met when a facility discharges wastewater to surface or groundwater of the state. The permit is jointly issued under two programs. The NPDES is a federal program established under the Clean Water Act, aimed at protecting the nation’s waterways from point and nonpoint sources. In Minnesota, it is administered by the Minnesota Pollution Control Agency (MPCA) under a delegation from the United States Environmental Protection Agency (USEPA). The SDS is a state program established under Minnesota Statutes 2008, section 115. In Minnesota, when both permits are required they are combined into one NPDES/SDS Permit administered by the state. The permits are issued to permittees discharging to a surface water of the state.
