Summary: 

ADEQ is in the process of revising water quality rules in Title 18 of the Arizona Administrative Code (A.A.C.) through expedited rulemakings. The objective of the rulemakings is to correct typographical errors, update outdated citations and references, clarify language, and fix similar clerical issues in Chapters 4, 5, 9, and 11, which will not add regulatory burden.
