Procedures, Permitting Process and Approvals for Right-of-Way Improvements

2.13 King County Permits and Approvals

Some projects may require a King County Waste Discharge Permit. These permits are needed if the discharge could be expected to contain chemicals or contaminants that differ from ordinary sewage. The permit is also needed when discharging drainage into a sanitary-only sewer. This is only allowed if the drainage is contaminated and it is not feasible to pre-treat and discharge to the drainage system. Get more information on the King County Waste Discharge Permit. For more information, call King County Department of Natural Resources and Parks at 206-263-3001.
