Chapter 173-501 WAC

This amendment will update the Chapter 173-501 WAC, Instream Resources Protection Program - Nooksack Water Resource Inventory Area (WRIA) 1 to meet the requirements in RCW 90.94.020.

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. 
We will develop technical findings and documentation to support rulemaking. We anticipate that supporting documentation for the rule would include: the estimated consumptive use of new domestic permit-exempt wells in the WRIA for the next 20 years, and projects and actions to offset potential impacts to instream flows associated with the permit-exempt domestic water use. The supporting documentation would include and evaluation for Net Ecological Benefit in the watershed to meet the requirements of the law.
 
The statute directs Ecology to begin rulemaking to meet the requirements of RCW 90.94.020 if a locally-approved watershed plan update is not adopted by Ecology by the deadline. A plan update was not submitted to Ecology for review and adoption, so Ecology is proceeding with the required rulemaking.
 
RCW 90.94.020 requires us to adopt rules for WRIA 1 by August 1, 2020.
