SB1128 Summary

• Amends Arizona's state implementation plan (SIP) process to require the director to consider all causal factors affecting air quality, including emission transport from other domestic states and effects of solar radiation and heat.

• Prohibits the director from considering emissions originating outside U.S. borders when revising the state implementation plan.

• Authorizes the Arizona Attorney General to sue the U.S. Environmental Protection Agency if the agency does not approve a demonstration that an Arizona area would meet national ambient air quality standards except for emissions from outside the United States.

• Establishes legislative findings that more than 80 percent of ozone pollution in the Maricopa nonattainment area originates from emissions outside the United States, and that Arizona would meet 2015 ozone standards but for foreign emissions.

• States that the EPA has misinterpreted federal law (42 U.S.C. § 7509a) regarding approval of state plans that account for out-of-state emissions.
