The U.S. Environmental Protection Agency (EPA) is finalizing, pursuant to the statutory framework established in the American Innovation and Manufacturing Act of 2020 (AIM Act), the eligibility of six applications to continue to receive priority access to allowances to produce or import hydrofluorocarbons. In this final rule, EPA establishes the framework for how EPA interprets the statutory criteria for assessing whether to renew the eligibility of applications to receive application-specific allowances and sets out determinations to renew or not renew each of the six applications that currently receive application-specific allowances. EPA is also finalizing revisions to the Technology Transitions regulations relevant to the specific applications under review, a procedural process for submitting a petition to designate a new application as eligible for priority access to allowances, the methodology used to allocate allowances to application-specific allowance holders for calendar years 2026 and beyond, and limited revisions to existing regulations. In addition, EPA is authorizing an entity to produce regulated substances for export. Lastly, EPA is finalizing certain regulatory confidentiality determinations for newly reported information.
Learn More🚛Proposed Rules for Heavy-Duty Vehicle Inspections in California
The U.S. Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove or, in the alternative, to fully approve a submission by the State of California to revise its State Implementation Plan (SIP) relating to the control of emissions from non-gasoline combustion vehicles over 14,000 pounds. EPA is proposing to disapprove the State's "Heavy-Duty Inspection and Maintenance Regulation" to the extent it applies to vehicles registered out-of-state or out-of-country. The EPA has substantial concerns that the State has not provided adequate assurances under Clean Air Act (CAA) section 110(a)(2)(E)(i) that implementation of the SIP is not prohibited by Federal law. EPA seeks comment on this and other aspects of this proposed rule. If finalized as a partial approval and partial disapproval, this rule would allow certain aspects of the covered State regulations to go into effect and would not trigger CAA section 179 sanctions because the submittal is not a required submission under CAA section 110(a)(2). If finalized as an approval, this rule would allow all covered State regulations to go into effect.
