Updated Vehicle Emissions Control Rule (Arizona Administrative Code Title 18, Chapter 2, Article 10)

Summary:
ADEQ received an exemption from the Governor's rulemaking moratorium to rewrite Arizona Administrative Code Title 18, Chapter 2, Article 10. The updated rule:

• Brings the Vehicle Emissions Inspection Program (VEIP) in line with federal regulations
• Implements HB 2357 (2005) and HB 2226 (2014) into the rule
• Allows the VEIP to leverage new technology
• Codifies VEIP practices that were simplified as a result of process improvements
• Reduces excessive audits

Arizona’s VEIP is run pursuant to Arizona Revised Statutes Title 49, Chapter 3, Article 5. The VEIP has been approved by the Environmental Protection Agency (EPA) as a part of Arizona’s State Implementation Plan (SIP). The VEIP remains an integral part of the Arizona SIP, and a key cog in the state’s ability to meet National Ambient Air Quality Standards (NAAQS). A VEI program is an “applicable requirement” for the Phoenix carbon monoxide (CO) and ozone planning areas under the EPA’s anti-backsliding provisions.

Amendment of Arizona Mercury Rule (R18-2-701, R18-2-733, R18-2-733.01, R18-2-734)

Summary:
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.

NSPS/NESHAPs/Acid Rain Incorporation by Reference (18 Arizona Administrative Code 2, Article 2)

Summary:
ADEQ proposed to adopt new and updated incorporations by reference of the following federal regulations in state rules: New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), Acid Rain and other parts of Title 40 Code of Federal Regulations (CFR). ADEQ proposed to update all of the incorporations by reference in order to continue its delegated authority from the Environmental Protection Agency (EPA) to implement and enforce NSPS, NESHAP and acid rain programs in Arizona, except for those specific authorities retained by the EPA. The updates include federal regulations finalized between July 1, 2006, and June 28, 2013.

Sulfur Dioxide (SO2) Updates for Hayden and Miami Planning Areas (18 Arizona Administrative Code 2, Article 2)

Summary:
ADEQ is considering amendments to R18-2-715 and R18-2- 715.01 in order to establish new emissions limitations for Existing Primary Copper Smelters within designated nonattainment areas for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS). On June 22, 2010, EPA revised the one-hour average and annual average NAAQS for SO2. 75 FR 35520. On Aug.5, 2013, the Environmental Protection Agency published new designations for the NAAQS for the Hayden and Miami nonattainment areas, effective Oct. 4, 2013. 78 FR 47191. The rules will become part of the State Implementation Plans (SIPs) for both areas.
