In addition to these permit triggers, Ecology reserves the right to require permit coverage at a construction site of any size, if Ecology believes that the site may be a significant contributor of pollutants to waters of the State of Washington or reasonably expects the site to cause a violation of water quality standards.

ADs that accept up to 30% (by volume) of off-farm pre-consumer food waste as digester feedstock (to be mixed with dairy manure) must apply for this permit exemption unless they are applying for the solid waste handling permit. ADs in compliance with the exempt conditions are limited in how they may use digestate solids and liquids. Use is allowed on the dairy as described in their updated nutrient management plan. The updated nutrient management plan must account for the added nutrients from the off-farm pre-consumer food waste.

The permit is used to temporarily increase the licensed weight of a vehicle, but not more than legal capacity. Before purchasing temporary addition tonnage the vehicle must be licensed to at least 40,000 pounds for solo units and 80,000 pounds for combinations. A Temporary License Permit (Trip Permit) may be used to increase licensed weight to the required 40,000 or 80,000 pounds to qualify for the temporary Additional Tonnage Permit (additional tonnage may not be sold for periods greater than the period covered by the Trip Permits). Minimum permit duration 5 days.

Temporary License Permits (also known as Trip Permits) allow vehicle owners to operate their unlicensed vehicles on public roadways. A vehicle is considered unlicensed if: the vehicle tabs are expired or the current gross weight isn't enough for the load being carried. These permits cannot be used in lieu of tonnage for a vehicle currently licensed in Washington but can be used to increase current tonnage. Permits are valid 3 consecutive days and no more than 3 permits can be issued for any 1 vehicle within a 30-day period.

All WTPs that discharge backwash effluent to surface water and that meet all of the following conditions must obtain coverage:

  • Produce potable water or "industrial" water (primary treatment/settled water) where the treatment and distribution of water is the primary function of the facility.

  • Have an actual production rate equal to or greater than 35,000 gallons per day of treated product water (finished water) as determined on an average monthly basis. "Actual production rate" is the amount of finished water that a treatment facility actually produces on any given day. To calculate the value of the actual production rate on an average monthly basis, add the value of each daily production rate during a calendar month, and divide the sum by the total number of days in the month. The Washington State Department of Ecology reserves the right to determine that permit coverage is needed for facilities with actual production rates less than 35,000 gallons per day in order to protect water quality.

  • The wastewater discharge is from water treatment filtration processes (filter backwash, sedimentation/pre-sedimentation basin washdown, sedimentation/clarification, or filter-to-waste).

  • The water treatment works are not part of a larger, permitted facility, such as a pulp and paper mill.

A WTMF is not required. It is a tool that can be used to make water type changes based on field verification. Prior to submittal of a forest practices application/notification, forest landowners are required to determine, in the field, the type of any regulated waters as identified in the forest practices rules (WAC 222) within proposed harvest boundaries, including the area within 200 feet of the proposal.

If you plan to conduct work in, over, or under navigable waters of the United States you must apply for authorization from the U.S. Army Corps of Engineers (Corps). The Corps authorizes activities by issuing individual and general permits. Individual permits include Standard Individual Permits and Letters of Permission, and general permits include Nationwide Permits and Regional General Permits. The Corps determines which type of permit is needed. A Department of the Army permit can include authorization under Section 10 and/or Section 404. If you have questions about the Corps permit process, contact the Corps project manager assigned to the county where the work is proposed.


Please take time to read the site disclaimer.   If you are new to Washington State regulations, we suggest you start at the Project Questionnaire which will guide you to permits you may need based on an interview process.
