Chapter 173-224 WAC

On June 22, 2021, we adopted rule amendments for Chapter 173-224 WAC – Water Quality Permit Fee. RCW 90.48.465 requires Ecology to establish, by rule, annual fees to recover the cost of administering the wastewater and stormwater permit programs. 

The rule adoption included an amendment for Fiscal Years 2022 and 2023 to recover the projected program costs. We adopted new permit fee categories, changes to the structure of specific permit fee categories, and other technical changes.
