EPA Finalizes Project Emissions Accounting Rule for New Source Review Permitting Determinations

On October 22, 2020, the U.S. Environmental Protection Agency (EPA) published a prepublication version of a final rule clarifying the process for existing air pollution sources to determine whether the New Source Review (NSR) permitting program applies to proposed projects. The new rule clarifies and confirms that project emissions accounting can be considered during Step 1 of the two-step NSR applicability test, meaning that both emissions increases and decreases from the proposed modification will be considered. The two steps of the NSR applicability test consist of a first step to determine whether a proposed project will cause a significant emission increase of a regulated NSR pollutant and, if it would, the second step determines if there will be a significant net emission increase of the same regulated NSR pollutant considering all other contemporaneous emissions increases and decreases.

EPA Revises National Emission Standards for Hazardous Air Pollutants General Provisions to Allow Major Sources to Reclassify as Area Sources

On October 1, 2020, the U.S. Environmental Protection Agency (EPA) issued a prepublication version of a final rule under the Clean Air Act that will allow major sources of hazardous air pollutants (HAP) to reclassify as area sources if the source reduces its potential to emit HAPs below the major source threshold (10 tons per year of any single HAP or 25 tons per year of any combination of HAPs). EPA had previously applied a “once in, always in” interpretation through a May 1995 policy memorandum issued by John Seitz, then-Director of EPA’s Office of Air Quality Planning and Standards. Under that policy, a facility designated as a major source on the first substantive compliance date of an applicable major source National Emission Standards for Hazardous Air Pollutants rule had to retain its major source status regardless of whether the source subsequently reduced its potential to emit below major source thresholds. But on January 25, 2018, EPA withdrew the May 1995 policy, laying the groundwork for EPA’s action here.

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.
