WAC 173-501, IRPP Nooksack WRIA 1 - Formal comment period

Chapter 173-501 WAC - WRIA 1 rule amendment

Nov. 19, 2019 - Jan. 17, 2020, 11:59 p.m.

Comments due: January 17, 2020, 11:59 p.m.

We are requesting comments on the rule amendment, the economic analyses, the rule supporting document, and the DNS. Submit by: Online, mail, or at one of the public hearings.

This rulemaking would amend Chapter 173-501 WAC, Instream Resources Protection Program - Nooksack Water Resource Inventory Area (WRIA) 1.

The rule amendment will update and add to water management regulations in WRIA 1 to meet the requirements in RCW 90.94.020. We will consider amending the rule to:

  • Add flexibility for projects that retime high flows for instream resource benefits.
  • Establish domestic permit-exempt groundwater withdrawal limits for new users.
  • Make minor technical corrections. 

Visit our Chapter 173-501 WAC rulemaking page for more information and documents for review.

We write rules to implement and enforce state and federal environmental laws and rules.  Ecology follows a 3-phase process for rulemaking:

  1. Announcement and development
  2. Proposal
  3. Adoption

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 Ecology’s rulemaking process, read the Frequently Asked Questions.
