Chapter 173-224 WAC – Water Quality Permit Fees
On July 1, 2025, Ecology adopted amendments to Chapter 173-224 WAC - Water Quality Permit Fees. The purpose of this chapter is to provide a permit fee system for state waste discharge and National Pollutant Discharge Elimination System (NPDES) permits issued by Ecology pursuant to RCW 90.48.160, 90.48.162, or 90.48.260
Chapter 173-224 WAC implements RCW 90.48.465 that requires Ecology to establish, by rule, annual fees to recover the cost of administering the wastewater and stormwater permit programs. The rule amendment considers the economic impact on small discharges and public entities, and provides appropriate adjustments where applicable.

Rule development phase
Aug. 7, 2024 - Spring 2025Public input & involvement
On Oct. 21, 2024, we hosted an online session to learn from community members about environmental justice considerations that may be connected to this rule. This was not a formal public hearing. We will schedule formal public hearings later in the rule process.
We provided a brief presentation on the purpose and function of the rule and sought feedback from participants.
This session was focused on hearing from:
- People who are not usually involved with Ecology’s work.
- Community members who are directly affected by this topic.
- Individuals who are especially vulnerable to pollution risks in the water.
- Those who consume fish or drink untreated water from local sources.
