2023 California Code › Water Code - WAT › DIVISION 7 - WATER QUALITY › CHAPTER 7.3 - Potable Reuse › Section 13561.2.

13561.2. (a) On or before December 31, 2023, the state board shall adopt uniform water recycling criteria for direct potable reuse through raw water augmentation. In adopting the initial uniform recycling criteria for direct potable reuse through raw water augmentation, the state board shall comply with all of the following:
(1) The state board shall develop the uniform water recycling criteria for direct potable reuse through raw water augmentation using information from the recommended research described in subdivision (b) of Section 13560.5 after soliciting stakeholder input from water agencies, wastewater agencies, local public health officers, environmental organizations, environmental justice organizations, public health nongovernmental organizations, and the business community.
(2) Before adopting uniform water recycling criteria for raw water augmentation, the state board shall submit the proposed criteria to the expert review panel established pursuant to subdivision (c). The expert review panel shall review the proposed criteria and shall adopt a finding as to whether, in its expert opinion, the proposed criteria would adequately protect public health.
(3) The state board shall not adopt uniform water recycling criteria for raw water augmentation pursuant to this subdivision unless and until the expert review panel adopts a finding that the proposed criteria would adequately protect public health.
(4) If the state board finds it will be unable to adopt the uniform water recycling criteria by December 31, 2023, the state board may, by June 30, 2023, extend the uniform water recycling criteria deadline by up to 18 months.
(5) If the state board finds that it needs longer than the deadline that has been extended pursuant to paragraph (4), the state board shall do all of the following:
(A) Post on its Internet Web site the date by which it intends to adopt the uniform water recycling criteria.
(B) If the state board determines that the recommended research described in subdivision (b) of Section 13560.5 is insufficient, consult with the expert review panel described in subdivision (c) regarding the research and, if necessary, the need for additional scientific and technical research. The expert review panel shall also determine the scientific and technical research necessary for the state board to complete the uniform water recycling criteria, including an estimated timeframe needed to conduct the scientific and technical research.
(C) No later than June 30, 2024, post on its Internet Web site the findings and determinations made, if any, by the expert review panel described in subdivision (c) under subparagraph (B).
(b) Nothing in this section shall prohibit the state board from using its existing authority to permit potable reuse projects pursuant to Section 116550 of the Health and Safety Code before the adoption of uniform recycling criteria pursuant to this section.
(c) (1) Before adopting the initial uniform water recycling criteria for direct potable reuse through raw water augmentation, the state board shall establish and administer an expert review panel for purposes of subdivision (a) and, if the state board deems it necessary, to provide additional scientific and technological research or to recommend a source of either existing research or research to be produced on direct potable reuse through raw water augmentation. After the state board has adopted the initial uniform water recycling criteria for raw water augmentation, the state board may reconvene or reestablish the expert review panel, if the state board deems it necessary, to provide additional scientific and technological research or to recommend a source of either existing research or research to be produced on raw water augmentation. In establishing and administering an expert review panel, the state board may contract with public or nonprofit research entities.
(2) Each member of the expert review panel shall receive one hundred dollars ($100) for each day the member attends a meeting of the expert review panel or of the state board plus actual and necessary travel expenses, including expenses for lodging and meals, and for each day the member spends conducting other official business of the expert review panel.
