EPA Proposes “Good Neighbor” Plan Addressing Regional Ozone Transport for the 2015 Ozone National Ambient Air Quality Standard

On April 6, 2022, the U.S. Environmental Protection Agency (EPA) is scheduled to publish its proposed Federal Implementation Plan Addressing Ozone Transport for the 2015 Ozone National Ambient Air Quality Standards (NAAQS), otherwise known as the latest iteration of EPA’s Cross-State Air Pollution Rule or “Good Neighbor” Plan. The proposal would subject 26 upwind states to the “good neighbor” or “interstate transport” provision of the Clean Air Act because EPA is proposing to find that nitrogen oxide (NOx) emissions, which are a precursor to ozone formation, from the upwind states significantly contribute to downwind states’ attaining and maintaining the 2015 ozone NAAQS.

EPA Grants States’ Petition for Reconsideration of Ozone National Ambient Air Quality Standards

Last week, the U.S. Environmental Protection Agency (EPA) granted petitions to reconsider air quality standards for ground-level ozone pollution set under the Trump administration in December 2020. Petitions were filed by a number of states, including New York, California, and the District of Columbia as well as various environmental groups. Currently, both primary and secondary ozone National Ambient Air Quality Standards remain at their 2015 levels of 70 parts per billion (ppb) over an eight-hour period. (more…)

Ninth Circuit Sends San Joaquin Valley Ozone Plan Back to EPA

On Thursday, the U.S. Court of Appeals for the Ninth Circuit granted a petition for review of the Environmental Protection Agency (EPA) final rule approving the State of California’s plan for meeting the ozone air quality standard in the San Joaquin Valley and remanded the plan to EPA for further consideration. EPA approved the plan in 2019, which included a single contingency measure that would be activated if the plan did not achieve reasonable further progress toward meeting the ozone standard. A local environmental group, the Association of Irritated Residents (AIR), challenged the approval and argued that the single contingency measure was arbitrary and capricious because it provided for only nominal emissions reductions.

EPA’s Proposal to Freeze Ozone National Ambient Air Quality Standards Issued in Anticipation of Criticism

On August 14, the U.S. Environmental Protection Agency (EPA) published its proposal to retain the existing ozone national ambient air quality standards (NAAQS). The proposal sets an October 1 deadline for public comment and schedules two virtual hearings, for August 31 and September 1, 2020. The current ozone NAAQS were established in 2015 and set 70 parts per billion for both primary and secondary standards.

District Court Imposes Deadline on EPA to Issue “Good Neighbor” Plans for Ozone Compliance

On July 28, Judge John Koeltl of the U.S. District Court for the Southern District of New York ordered the U.S. Environmental Protection Agency (EPA) to issue Federal Implementation Plans for the 2008 ozone National Ambient Air Quality Standards (NAAQS) that fully address the “good neighbor” obligations under the Clean Air Act by March 2021. The plans will force upwind Northeastern states (Illinois, Indiana, Michigan, Ohio, Pennsylvania, Virginia, and West Virginia) to curb air emissions that otherwise impede the ability of neighboring downwind states (New York, Connecticut, New Jersey, and Massachusetts) from meeting the statutory July 20, 2021 attainment deadline set forth in the 2008 ozone NAAQS.
