Permits - Point Source Pollution

The state of Washington, Department of Ecology, Water Quality Program, is delegated by the U.S. EPA as the state water pollution control agency, responsible for implementing all federal and state water pollution control laws and regulations.  Wastewater and stormwater discharges are regulated primarily by wastewater discharge permits, which stipulate specific limits and conditions of allowable discharge.

A wastewater discharge permit is required for disposal of waste material into "waters of the state," which include rivers, lakes, streams, and all underground waters and aquifers.  A wastewater discharge permit is also required for certain industrial users that discharge industrial waste into sanitary sewer systems. A wastewater permit may be required for facilities that have stormwater runoff to surface waters.

This website has information on general permits and individual permits, and other- permit information including the Permit Writer's Manual, car wash guidance manual, water quality data, and wastewater discharge permit fees.

A link to EPA's National Pollutant Discharge Elimination System (NPDES) application forms can be found on the  permit application forms page. You will also find links to Washington's state wastewater discharge permit applications.
