EPA approves AVAQMD NSR permit rules
The EPA is approving AVAQMD Rules 1301, 1302 (except subsections 1302(C)(5) and 1302(C)(7)(c)), 1303, 1304, 1305, 1309 (all dated December 30, 2024) and new Rule 1314 (adopted July 15, 2025) into the California SIP. This action is effective August 17, 2026, updates the District's New Source Review permitting program for new and modified pollution sources, and resolves the deficiencies cited in the EPA's 2023 NSR action.
Termination of stayed and deferred sanctions
Because the EPA determined the District corrected the prior deficiencies, the sanctions that had been stayed and deferred by the March 26, 2025 interim final determination are now terminated and a Federal implementation plan under CAA section 110(c) is no longer required. This termination is effective with this final rule.
New Rule 1314 added for ozone precursors
The EPA is incorporating AVAQMD Rule 1314, 'Federal Nonattainment New Source Review for Ozone Precursors,' adopted locally on July 15, 2025 and submitted to EPA on October 16, 2025, into the California SIP effective August 17, 2026. This adds SIP-level permitting requirements specifically addressing ozone precursor emissions in the District.
No added federal costs to small entities
The EPA states this approval 'does not impose additional requirements beyond those imposed by state law' and certifies the action 'is not having a significant economic impact on a substantial number of small entities' under the Regulatory Flexibility Act. The final rule therefore does not create new federal-cost obligations for small businesses in the District.
