Overview of Permits and Who Regulates Them

The City of Sioux Falls implements local stormwater controls through its Public Works and Engineering divisions and enforces ordinances adopted by the City Council. Some construction-related stormwater permits and the statewide NPDES requirements are administered at the state level by the South Dakota Department of Environment and Natural Resources (DENR); project applicants should confirm whether a state NPDES construction permit is also required.
