In July 1995, Ecology issued three NPDES wastewater discharge general permits to regulate municipal stormwater discharges. These permits required development and implementation of stormwater management programs to reduce the discharge of pollutants to the maximum extent practicable. The permits expired on July 5, 2000. Ecology administratively extended permit coverage until they issue the revised permit in January 2007.
Ecology combined the three current general permits for the Island/Snohomish, Cedar/Green, and South Puget Sound Water Quality Management Areas (WQMA) into a single statewide general permit. The general permit applies to all entities required to have permit coverage under current (Phase I) U.S. Environmental Protection Agency stormwater regulations. This includes cities and unincorporated portions of counties whose populations exceed 100,000. The 1995 Phase I permittees include:
