Permit fees

State law (RCW 90.48.465) requires that all permittees pay an annual permit fee based upon the state fiscal year. The state fiscal year begins each year on July 1 and ends on June 30 the following year. Ecology sends permit fee invoices to all permittees annually. Permittees who have permit coverage on or after July 1 will receive a permit fee invoice for coverage during that state fiscal year. If you would like more information on the permit fee process, visit our Permit Fees webpage or contact the Fee Unit at wqfeeunit@ecy.wa.gov or (800) 633-6193/Option 2.
