The list of circumstances under which a water provider may qualify for monies in the Fund is expanded to include that the water provider is located in a county with a population of less than 1.5 million persons (all except Maricopa County).

Summary: The term “waters of the United States” or “WOTUS” replaces the term “navigable water” in various statutes in order to conform to changes in the federal Clean Water Act. The Arizona Department of Environmental Quality (ADEQ) is required to adopt rules for water quality standards for non-WOTUS protected surface waters by December 31, 2022, and requirements for the rules are specified. ADEQ is required to maintain and publish a protected surface waters list, and to adopt the list by rule no later than December 31, 2022. Waters that ADEQ must include and waters that ADEQ is prohibited from including on the protected surface waters list are specified. By December 31, 2022 and at least once every five years after, ADEQ is required to prepare a list of impaired non-WOTUS protected surface waters. Establishes special provisions for discharges to non-WOTUS protected surface waters. Requires ADEQ to adopt rules for best management practices for activities within non-WOTUS.

Summary: In the Pinal Active Management Area, for an application to modify or renew a designation of assured water supply, or for a new application for a designation for the same service area to be served by a substitute provider acquiring the assets of the prior provider, if specified conditions apply to the volume of groundwater and stored water, the Department of Water Resources (DWR) is prohibited from reviewing the physical availability of groundwater that was determined to be physically available under the previous designation. Does not affect the DWR review of assured water supply criteria other than the physical availability of groundwater and stored water to be recovered outside the area of impact of storage. The following are deemed physically available for purposes of an assured water supply designation: stored water that is to be recovered by the applicant within the "area of impact" (defined) under long-term storage credits pledged to the designation, and stored water that is to be recovered by the applicant within the area of impact of storage either on an annual basis or as long-term storage credits to be earned in the future if the water to be stored meets the physical availability requirements for the water supply. Contains a legislative intent section.
