Chapter 173-217 WAC – State Waters Alteration Permit
The Department of Ecology is beginning a rulemaking for a new rule, Chapter 173-217 WAC to establish a formal permitting program for projects that could alter or impact wetlands, streams, and other state waters. Currently, we issue administrative orders under the Water Pollution Control Act to authorize projects seeking to alter or impact state waters. While administrative orders protect the environment, the process lacks public notice opportunities and timeline obligations for issuing decisions.
The new statewide permitting program will improve customer service by:
- Providing better clarity and predictability regarding our actions and requirements
- Creating general permits to streamline approvals for projects with minor impacts
- Establishing opportunities for public review
- Setting mitigation requirements for projects
