Overview
Authorizes certain water quality programs within the Arizona Department of Environmental Quality to cover waters that are no longer considered "waters of the United States."
History
Clean Water Act
The Clean Water Act prohibits discharges of pollutants into "waters of the United States" (WOTUS) unless a permit is obtained from one of this law's regulatory programs. This law also delegates certain responsibilities to state governments. To that end, the Arizona Department of Environmental Quality (ADEQ) administers:
1) Arizona Pollutant Discharge Elimination System (APDES) Program—This program regulates point source discharges of pollutants and storm water runoff into WOTUS in Arizona (A.R.S. § 49-255 et seq.). This program issues either general permits, which cover discharges within a geographic area, or individual permits that cover a single point source, facility, or municipal separate storm sewer system (R18-9-A901(12) and (13)).
2) Water Quality Standards—ADEQ has adopted water quality standards in rule for WOTUS to protect those waters for present and future uses based on factors such as current use and the protection of public health (18 A.A.C. 11). Standards can also be established for other waters, such as pumped groundwater that is not used for drinking water (A.R.S. § 49-221 et seq.); and
3) Total Maximum Daily Load Program—When a water does not meet water quality standards, ADEQ, through the Total Maximum Daily Load program, establishes limits on the amount of pollutants this water can receive and still meet water quality standards. These limits are implemented through permit limitations and ADEQ's Nonpoint Source Program (A.R.S. § 49-231 et seq.).
Defining Waters of the United States
In response to a 2017 executive order, the U.S. Environmental Protection Agency and Army Corps of Engineers adopted a narrower definition of WOTUS, which became effective in June 2020 (85 Federal Register 22250). As a result of this change, certain waters within Arizona are no longer covered under the Clean Water Act.

47. Instructs the ADEQ Director to apply the APDES Program rules to non-WOTUS protected surface waters until that official adopts rules for discharges to non-WOTUS protected surface waters, except that the ADEQ Director is not required to follow any provisions related to EPA review, approval or involvement in permit review or approval. (Sec. 22)
48. Prohibits the ADEQ Director from adopting or applying rules for the following discharges to non-WOTUS protected surface waters:
a) Requirements for new sources or discharges under the Clean Water Act to non-WOTUS protected surface waters except for those from publicly owned treatment works.
