Summary:The Arizona Department of Environmental Quality (ADEQ) is proposing amendments to the state standards for emissions of mercury by coal-fired electric utility steam generating units (EGUs) in R18-2-733, -733.01 and -734 (the “Arizona Mercury Rule”) that would revise those rules to reflect EPA’s repeal of its cap-and-trade program for mercury emissions and adoption of maximum achievable control technology (MACT) standards. Specifically, the amendments would (i) repeal provisions of the Arizona Mercury Rule (R18-2-733 and -733.01) that incorporate and modify the now defunct cap-and-trade program and (ii) amend the emission limits in R18-2-734 to be consistent with the MACT standards.

Effective Date of Rule: July 1, 2016
Summary: ADEQ seeks to establish new and reasonable fees for the certification of drinking water and wastewater operators. A.R.S. §§ 49-352(A) and 49-361(2) require ADEQ to adopt, establish, and enforce rules for the certification of operating personnel according to the skill, knowledge, and experience required for the applicable certification, and include authority for ADEQ to charge fees for water and wastewater operator certifications. ADEQ’s Operator Certification Program has been funded by state general fund, federal grants and federal set-asides but these funds have significantly decreased.

Operators of water treatment plants and water distribution systems, and wastewater collection systems and wastewater treatment plants are responsible for all decisions about process control or system integrity that affects public health. The operator certification rules establish the requirements for certification and classification, examinations, renewal of certificates, expired certificates, revocation, reciprocity for out-of-state applicants, and experience and education.
