Conditional Approval of Arizona State Implementation Plan Revisions; Maricopa County Air Quality Department; Mobile Source Emission Reduction Credits
Document Number: 2024-18570
Type: Proposed Rule
Date: 2024-08-22
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to conditionally approve a revision to the Maricopa County Air Quality Department's (MCAQD or "Department") portion of the Arizona State Implementation Plan (SIP). This rule revision establishes a program allowing fleet owners/operators to generate emission reduction credits (ERCs) by either retrofitting or replacing existing fleet vehicles with lower emitting vehicles and meeting other ongoing requirements. These ERCs are intended for use as offsets under the Department's nonattainment New Source Review (NNSR) program. We are taking comments on this proposal and plan to follow with a final action.
