The SWT Program investigates complaints and enforces regulations on improper storage, disposal and handling of moderate risk waste; provides community education to ensure that moderate risk waste does not impact public health or the environment; conducts assessment of contaminated sites; technical assistance visits to small businesses and investigates illegal drug labs. Requirements for hazardous waste are regulated under the SHD Sanitary Code.

  • Household hazardous waste such as waste oil, antifreeze, gasoline, oil-based paints, solvents, and pesticides can not go into the garbage and can be disposed of free of charge at Snohomish County's Household Hazardous Waste Facility.
  • Residential heating oil tanks can be either under-ground or above ground tanks used to store oil to heat homes. Snohomish Health District has no specific rules for these tanks unless they leak and cause a public health nuisance. There is free insurance for home owners of tanks through the State of Washington Pollution Liability Insurance Agency (PLIA) if owners register before the tank leaks. Please consult your local Fire Marshal and city or county building department about tank removal or other questions. Also see the Washington State Department of Ecology information.

Local Source Control Program
In 2008 the Washington State Department of Ecology issued grants to 14 cities and counties in an effort to protect Puget Sound from impacts of stormwater runoff. The health of our environment, our water systems is essential to the health and vitality of our families and communities. We focus on preventing sources of pollution from entering the environment that we all live in.
The Local Source Control program offers education and technical assistance to Snohomish County small businesses, schools and government entities in the areas of spill prevention, waste management, and stormwater issues. We provide constructive feedback on site so businesses can reduce the environmental threat of toxic and hazardous wastes, as well as helping manage, the reuse and recycling of solid waste.
