EPA entered into a proposed consent decree under the CAA in California Communities Against Toxics v. Regan, No. 1:22-cv-1457 (D.D.C.), that would establish deadlines for the EPA Administrator to sign a notice of proposed rulemaking and a final rule regarding NESHAPs for chemical manufacturing area sources.

EPA granted the California Air Resources Board’s request for authorization of amendments to its Ocean-Going Vessels At-Berth regulation. 

The EPA Administrator found that engine emissions of lead from certain aircraft cause or contribute to the lead air pollution that may reasonably be anticipated to endanger public health and welfare under the CAA. 

EPA entered into a proposed consent decree in Center for Biological Diversity v. United States Environmental Protection Agency, No. 2:23-cv-01843 (E.D. Pa.) that would establish a deadline for EPA to complete a reconsideration of its approval of two revisions to Pennsylvania’s SIP that addressed certain reasonably available control technology requirements.

EPA proposed to establish recordkeeping and reporting requirements for uses of ozone-depleting substances as process agents and to update definitions to reflect current practice. 

EPA announced that it has issued calendar year 2024 allowances for the production and consumption of hydrofluorocarbons under the American Innovation and Manufacturing Act. 

EPA proposed to issue regulations to implement certain provisions of the American Innovation and Manufacturing Act; the proposed rulemakings would establish a program for the management of hydrofluorocarbons and alternative RCRA standards for spent ignitable refrigerants being recycled for reuse.

EPA found that 11 states failed to submit SIP revisions required by the CAA in a timely manner for certain nonattainment areas classified as moderate for the 2015 ozone NAAQS: Arizona, California, Connecticut, Delaware, Illinois, Indiana, Michigan, New Jersey, Nevada, Texas, and Wisconsin. 

SIP Proposal: California (nonattainment new source review requirements for the 2015 eight-hour ozone NAAQS in the Butte County Air Quality Management District).

SIP Approval: Virginia (second maintenance plan for the 1997 eight-hour ozone NAAQS in the Norfolk-Virginia Beach-Newport News, VA Area).
