(1) Unless requirements are otherwise specified in the applicable rules adopted under this chapter or 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)(a) 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 either not adopted a watershed plan, or adopted a partial watershed plan, under chapter 90.82 RCW, the department shall establish watershed restoration and enhancement committees in the following water resource inventory areas: 7 (Snohomish); 8 (Cedar-Sammamish); 9 (Duwamish-Green); 10 (Puyallup-White); 12 (Chambers-Clover); 13 (Deschutes); 14 (Kennedy-Goldsborough); and 15 (Kitsap).

(b) The department shall chair the watershed restoration and enhancement committee and invite the following entities to participate:

(i) A representative from each federally recognized Indian tribe that has reservation land within the water resource inventory area;

(ii) A representative from each federally recognized Indian tribe that has a usual and accustomed harvest area within the water resource inventory area;

(iii) A representative from the department of fish and wildlife, appointed by the director of the department of fish and wildlife;

(iv) A representative designated by each county within the water resource inventory area;

(v) A representative designated by each city within the water resource inventory area;

(vi) A representative designated by the largest irrigation district within the water resource inventory area;

(vii) A representative designated by the largest publicly owned water purveyor providing water within the water resource inventory area that is not a municipality;

(viii) A representative designated by a local organization representing the residential construction industry within the water resource inventory area;

(ix) A representative designated by a local organization representing environmental interests within the water resource inventory area; and

(x) A representative designated by a local organization representing agricultural interests within the water resource inventory area.

(3) By June 30, 2021, the department shall prepare and adopt a watershed restoration and enhancement plan for each watershed listed under subsection (2)(a) of this section, in collaboration with the watershed restoration and enhancement committee. Except as described in (h) of this subsection, all members of a watershed restoration and enhancement committee must approve the plan prior to adoption.

(a) The watershed restoration and enhancement plan should include recommendations for projects and actions that will measure, protect, and enhance instream resources and improve watershed functions that support the recovery of threatened and endangered salmonids. Plan recommendations may include, but are not limited to, acquiring senior water rights, water conservation, water reuse, stream gaging, groundwater monitoring, and developing natural and constructed infrastructure, which includes but is not limited to such projects as floodplain restoration, off-channel storage, and aquifer recharge. Qualifying projects must be specifically designed to enhance streamflows and not result in negative impacts to ecological functions or critical habitat.

(b) At a minimum, the plan must include those actions that the committee determines to be necessary to offset potential impacts to instream flows associated with permit-exempt domestic water use. The highest priority recommendations must include replacing the quantity of consumptive water use during the same time as the impact and in the same basin or tributary. Lower priority projects include projects not in the same basin or tributary and projects that replace consumptive water supply impacts only during critical flow periods. The plan may include projects that protect or improve instream resources without replacing the consumptive quantity of water where such projects are in addition to those actions that the committee determines to be necessary to offset potential consumptive impacts to instream flows associated with permit-exempt domestic water use.

(c) Prior to adoption of the watershed restoration and enhancement plan, the department must determine that actions identified in the plan, after accounting for new projected uses of water over the subsequent twenty years, will result in a net ecological benefit to instream resources within the water resource inventory area.

(d) The watershed restoration and enhancement plan must include an evaluation or estimation of the cost of offsetting new domestic water uses over the subsequent twenty years, including withdrawals exempt from permitting under RCW 90.44.050.

(e) The watershed restoration and enhancement plan must include estimates of the cumulative consumptive water use impacts over the subsequent twenty years, including withdrawals exempt from permitting under RCW 90.44.050.

(f) The watershed restoration and enhancement plan may include:

(i) Recommendations for modification to fees established under this subsection;

(ii) Standards for water use quantities that are less than authorized under RCW 90.44.050 or more or less than authorized under subsection (4) of this section for withdrawals exempt from permitting;

(iii) Specific conservation requirements for new water users to be adopted by local or state permitting authorities; or

(iv) Other approaches to manage water resources for a water resource inventory area or a portion thereof.

(g) After adoption of a watershed restoration and enhancement plan, the department shall evaluate the plan recommendations and initiate rule making, if necessary, to incorporate recommendations into rules adopted under this chapter or under chapter 90.22 or 90.54 RCW. Any modification to fees collected under subsection (4) of this section or standards for water use quantities that are less than authorized under RCW 90.44.050 or more or less than authorized under subsection (4) of this section for withdrawals exempt from permitting may not be applied unless authorized by rules adopted under this chapter or under chapter 90.54 RCW.

(h) If the watershed restoration and enhancement committee fails to approve a plan by June 30, 2021, the director of the department shall submit the final draft plan to the salmon recovery funding board established under RCW 77.85.110 and request that the salmon recovery funding board provide a technical review and provide recommendations to the director to amend the final draft plan, if necessary, so that actions identified in the plan, after accounting for new projected uses of water over the subsequent twenty years, will result in a net ecological benefit to instream resources within the water resource inventory area. The director of the department shall consider the recommendations and may amend the plan without committee approval prior to adoption. After plan adoption, the director of the department shall initiate rule making within six months to incorporate recommendations into rules adopted under this chapter or under chapter 90.22 or 90.54 RCW, and shall adopt amended rules within two years of initiation of rule making.

(4)(a) Until a watershed restoration and enhancement plan is approved and rules are adopted under subsection (3) of this section, a city or county issuing a building permit under RCW 19.27.097(1)(d), or approving a subdivision under chapter 58.17 RCW in a watershed listed in subsection (2)(a) of this section must:

(i) Record relevant restrictions or limitations associated with water supply with the property title;

(ii) Collect applicable fees, as described under this section;

(iii) Record the number of building permits issued under chapter 19.27 RCW or subdivision approvals issued under chapter 58.17 RCW subject to the provisions of this section;

(iv) Annually transmit to the department three hundred fifty dollars of each fee collected under this subsection;

(v) Annually transmit an accounting of building permits and subdivision approvals subject to the provisions of this section to the department;

(vi) Until rules have been adopted that specify otherwise, require the following measures for each new domestic use that relies on a withdrawal exempt from permitting under RCW 90.44.050:

(A) An applicant shall pay a fee of five hundred dollars to the permitting authority;

(B) Except as provided in (b) of this subsection, an applicant may obtain approval for a withdrawal exempt from permitting under RCW 90.44.050 for domestic use only, with a maximum annual average withdrawal of nine hundred fifty gallons per day per connection; and

(C) An applicant shall manage stormwater runoff on-site to the extent practicable by maximizing infiltration, including using low-impact development techniques, or pursuant to stormwater management requirements adopted by the local permitting authority, if locally adopted requirements are more stringent.

(b) Upon the issuance of a drought emergency order under RCW 43.83B.405, the department may curtail withdrawal of groundwater exempt from permitting under RCW 90.44.050 and approved under this subsection (4) to no more than three hundred fifty gallons per day per connection for indoor use only. Notwithstanding the limitation to no more than three hundred fifty gallons per day per connection for indoor use only, an applicant may use groundwater exempt from permitting to maintain a fire control buffer during a drought emergency order.

(5) Rules adopted under this chapter or chapter 90.54 RCW may:

(a) Rely on watershed restoration and enhancement plan recommendations and procedures established in this section to authorize new withdrawals exempt from permitting under RCW 90.44.050 that would potentially impact a closed water body or a minimum flow or level;

(b) Rely on projects identified in the watershed restoration and enhancement plan to offset consumptive water use; and

(c) Include updates to fees based on the watershed restoration and enhancement committee's determination of the costs for offsetting consumptive water use.

(6) This section only applies to new domestic groundwater withdrawals exempt from permitting under RCW 90.44.050 in the following water resource inventory areas with instream flow rules adopted under chapters 90.22 and 90.54 RCW that do not explicitly regulate permit-exempt groundwater withdrawals: 7 (Snohomish); 8 (Cedar-Sammamish); 9 (Duwamish-Green); 10 (Puyallup-White); 12 (Chambers-Clover); 13 (Deschutes); 14 (Kennedy-Goldsborough); and 15 (Kitsap) and does not restrict the withdrawal of groundwater for other uses that are exempt from permitting under RCW 90.44.050.
