We invite you to comment on preliminary draft amendments to Chapter 173-201A WAC.
The rulemaking would adopt one or more variances to WAC 173-201A Water Quality Standards for organic compounds known as polychlorinated biphenyls (PCBs). We're considering the variances in response to five applications received from point source dischargers to the Spokane River.
Preliminary draft documents for review
We follow a 3-phase process in rulemaking to implement and enforce state and federal environmental laws and rules.
For each phase of the process, we update the rulemaking web page and notify interested parties. We also file notice in the Washington State Register. To learn more about our rulemaking process, read the Frequently Asked Questions
