The Wenatchee Valley Stormwater Technical Advisory Committee (WVSTAC) was formed in January 2004 through a memorandum of understanding between Chelan County, Douglas County, the City of East Wenatchee and the City of Wenatchee. The goal of this committee is to develop a regional stormwater program and meet the requirements of the Eastern Washington Phase II Municipal Stormwater Permit.
What's happening now ...
The Department of Ecology (Ecology) is supporting and leading an effort to update the 2004 Stormwater Management Manual for Eastern Washington (Manual), as it has been over 10 years since the Manual was written. The Manual provides guidance on measures necessary to protect the quality of stormwater in eastern Washington. Local jurisdictions have adopted the Manual to set stormwater requirements for new development and redevelopment projects in accordance with the Eastern Washington Phase II Municipal Stormwater Permit. Upon update of Ecology’s Manual, the finalized manual will become the standard for Chelan County, Douglas County, City of Wenatchee and City of East Wenatchee. Land developers and designers use the Manual to design permanent stormwater control plans, develop construction stormwater pollution prevention plans, and maintain stormwater infrastructure. Businesses, including industrial sites, use the Manual to help design their stormwater pollution prevention plans. The proposed 2018 Stormwater Management Manual for Eastern Washington will guide stormwater management for years to come. Input from the public will help Ecology create guidance that protects water quality while being useful and applicable to eastern Washington communities.
The Department of Ecology is accepting comments on the draft 2018 manual until 11:59 pm on July 25, 2018. Send your comments or questions to Ecology at: SWPermitComments@ecy.wa.gov.

Is washing my car at home prohibited?
No, you can continue to wash your car at home just wash your car sensibly so the soapy water does not get into the storm drains. If possible wash your car on grass or a gravel area so the wash water can filter into the ground. Use a hose with a shut-off nozzle to reduce the amount of water used. Pour your soapy water out in a sink or an area where it can filter into the ground instead of down the storm drain. For more information: Frequently Asked Questions About Vehicle Washing (pdf)
