ADEQ is proposing to update its safe drinking water rules in order to conform to changes made to federal rules over the past seven years. ADEQ plans to incorporate by reference the Revised Total Coliform Rule into a new section, and make corresponding changes in other sections. ADEQ also plans to incorporate by reference the 2007 changes to the Lead and Copper Rule. ADEQ is authorized to enforce federal drinking water standards under A.R.S. § 49-353(A)(2)(a).

ADEQ has published the Notice of Proposed Rulemaking for updates to the Safe Drinking Water rules (18 A.A.C. 4, Articles 1 and 2). The Notice of Proposed Rulemaking is available here (at page 2286): http://apps.azsos.gov/public_services/register/2015/41/04_proposed.pdf. Information on the Safe Drinking Water rulemaking and other ADEQ rulemaking is also available on ADEQ’s website.
