The definitions in this section apply throughout this chapter unless the context clearly requires otherwise.

(1) "Department" means the department of ecology.

(2) "Lead agency" has the same meaning as defined in RCW 90.82.060.

(3) "Water resource inventory area" or "WRIA" means a water resource inventory area established in chapter 173-500 WAC as it existed on January 19, 2018.

Intent—2018 c 1: "The legislature intends to appropriate three hundred million dollars for projects to achieve the goals of this act until June 30, 2033. The department of ecology is directed to implement a program to restore and enhance streamflows by fulfilling obligations under this act to develop and implement plans to restore streamflows to levels necessary to support robust, healthy, and sustainable salmon populations." [ 2018 c 1 § 304.]

(1) Unless requirements are otherwise specified in the applicable rules adopted under this chapter or under chapter 90.22 or 90.54 RCW, potential impacts on a closed water body and potential impairment to an instream flow are authorized for new domestic groundwater withdrawals exempt from permitting under RCW 90.44.050 through compliance with the requirements established in this section.

(2) In the following water resource inventory areas with instream flow rules adopted by the department under chapters 90.22 and 90.54 RCW that do not explicitly regulate permit-exempt groundwater withdrawals and that have completed a watershed plan adopted under chapter 90.82 RCW, the department shall work with the initiating governments and the planning units described in chapter 90.82 RCW to review existing watershed plans to identify the potential impacts of exempt well use, identify evidence-based conservation measures, and identify projects to improve watershed health: 1 (Nooksack); 11 (Nisqually); 22 (Lower Chehalis); 23 (Upper Chehalis); 49 (Okanogan); 55 (Little Spokane); and 59 (Colville).
