In April 2023, the California Air Resources Board (CARB) passed its Advanced Clean Fleets (ACF) rule, which will require California medium- and heavy-duty truck and bus fleet owners with over $50 million in annual revenue to transition to zero emission vehicles through a phaseout of their existing internal combustion engine–powered vehicles by 2045. On July 26, 2023, while the ACF rule was pending with the California Office of Administrative Law for a final determination prior to release, CARB withdrew the regulatory package with the intention of resubmitting it “at a subsequent date.” CARB is now forming a Truck Regulation Advisory Committee and, on August 22, 2023, will host a public meeting to discuss and solicit feedback on future efforts to implement the ACF rule. Instructions for participation in this public meeting can be found here.

U.S. EPA Removes Regulatory Affirmative Defense Provision Against Alleged Violations of Oil and Gas Facility NESHAPs

On October 22, 2024, the U.S. Environmental Protection Agency (EPA) published a final rule removing an affirmative defense from Clean Air Act (CAA) National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations for the Oil and Natural Gas Production Facility and Natural Gas Transmission and Storage Facility Source Categories (Final Rule).[1] Prior to the Final Rule, owners or operators could assert an affirmative defense that alleged NESHAP standard violations were caused by an equipment malfunction.[2] A “malfunction” is defined as any sudden, infrequent, and not reasonably preventable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner.[3]

EPA Issues Final Rule for Major Source Reclassification Under Clean Air Act Section 112

On Tuesday, September 10, the U.S. Environmental Protection Agency (EPA) issued a final rule establishing requirements for major sources of hazardous air pollutants — sources that emit or have the potential to emit 10 tons per year of a single hazardous air pollutant or 25 tons per year of a combination of hazardous air pollutants — that reclassify as area sources below these thresholds. Reversing a rule adopted during the Trump administration, the rule provides that sources emitting any of the seven persistent and bioaccumulative hazardous air pollutants listed under Section 112(c)(6) of the Clean Air Act must continue to comply with major source standards even if otherwise reclassified as area sources. As a result, reclassified sources will still be subject to maximum achievable control technology standards rather than less stringent standards applicable to area sources. In so doing, EPA maintains that at least 90% of the cumulative emissions of these pollutants will be subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) regardless of future source reclassifications.
