The proposed bill would update current statutes by allowing counties to claim concurrent jurisdiction over portable and mobile sources for the purpose of issuing, revising, or enforcing permits for emission reduction credits (ERCs). This is reflected in the insertion of new language that outlines the conditions for this authority, including a voluntary request from the applicant. The bill also clarifies that participation in ERC certification programs is voluntary and does not restrict the Arizona Department of Environmental Quality (ADEQ) from enforcing additional emission reductions if agreed upon during permit issuance.

Additionally, the bill modifies existing regulations by prohibiting control officers from certifying new surplus ERCs for mobile sources if participation in the ERC program becomes mandatory. It specifies that only mobile source fleets based in nonattainment areas are eligible for ERC certification by a county. The bill sets a maximum permit term of 20 years for ERC certification and ensures compliance with all applicable rules and conditions. Technical amendments include replacing terms for clarity and adjusting the fee structure for permits, allowing for increases based on the consumer price index and raising the maximum fee for certain permits to more than $25,000.
