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.

Spring Pollution Prevention
A clean Columbia starts in your backyard! Contaminated stormwater is the largest contributor to polluted water. This spring, it is important to remember that everything that hits the ground has potential to end up In the Columbia River if it reaches the road or a storm drain. As the weather warms and you’re spring cleaning and working in the yard, it is important to remember to always properly dispose of waste and chemicals. Here are some quick tips on how you can help prevent stormwater pollution this spring:
- Limit your usage of pesticides and fertilizers. Always follow the directions and never apply when rain is in the forecast.
- Check you sprinkler system for leaks and make sure your your system isn’t spraying the road, sidewalks, driveways and other hard surfaces. Leaks, overwatering, and spraying the hard surfaces wastes water, polluted water ways, and can cause damage to the road.
- Keep grass clippings and other yard debris out of the road and away from storm drains.
- Whether you’re at home, at the park, or out enjoying the foothills, always pick up after your pet.
- Always properly dispose of household chemicals properly. Never dump paint, household chemicals, soap, oil, food, or any other wastes into the road or into storm drains.

- There are NO DATES SCHEDULED in 2020 for Hazardous Household Chemicals in Douglas County for 2020.
Small changes at home can make a big difference to our local swimming areas, wildlife, and those that live downstream.
Mobile Contractor Education and Outreach Effectiveness Study
In 2016, cities and counties in Eastern Washington covered under the NPDES Municipal Stormwater permit were surveyed regarding types of illicit discharge complaints. It was discovered that complaints were primarily generated from four types of mobile businesses: painting contractors, carpet cleaners, concrete contractors, and food vendors. In 2010, the Wenatchee Valley took part in the "Dump Smart Program" and beginning in 2018, the a study began to evaluate the effectiveness of the Dump Smart Education and Outreach Program. The study was completed in 2019 and the final report of the study can be found here. Also available is a fact sheet summarizing the Mobile Contractor Illicit Discharge Education & Outreach Effectiveness Study, the fact sheet can be found here
