Water pollution degrades surface waters, making them unsafe for drinking, fishing, swimming, and other activities. As authorized by the Clean Water Act, the NPDES Permit Program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Since it's introduction in 1972, the NPDES Permit Program is responsible for significant improvements to our nation's water quality. The City of Valley Center has a current Kansas Water Pollutions Control General Municipal Separate Storm Sewer System (MS4) Permit and Authorization to Discharge under the NPDES issued on October 23, 2019 by the Kansas Department of Health and Environment.
