Commercial wastes—that are NON-domestic in nature
Pre-approval IS REQUIRED To protect the environment, our treatment plant and the quality of the valuable resources leaving our treatment plant King County is now requiring that businesses, commercial facilities, and industries sending septage to the county's facility have approval to do so. Businesses or sites that need an approval number may have the potential to discharge wastewater that contains metals or other chemicals that are not normally found in domestic septage (for example silver from x-ray machines found in medical offices, inks from print shops, or solvents from furniture makers/restorers). You must have the business supply you with their King County Industrial Waste Approval Number. Record the business name, address, phone number, business type, estimated volume pumped and approval number on the King County Hauled Waste Certification form.

- Auto repair shops, auto-body shops
