The Newest Phase of EPA’s Greenhouse Gas Emissions Standards: Phase 3
On March 29, 2024, the U.S. Environmental Protection Agency (EPA) announced its most recent national greenhouse gas (GHG) pollution standards for heavy-duty (HD) vehicles, including HD vocational vehicles and tractors. The rule establishes new CO2 emission standards for model year (MY) 2032 and later HD vehicles, with more stringent CO2 standards phasing in as early as MY 2027 for certain vehicle categories.
California Air Resources Board Will Workshop Omnibus Regulation Amendments
The California Air Resources Board (CARB) announced that it will hold a public workshop to discuss amendments to its Heavy-Duty (HD) Engine and Vehicle Omnibus (Omnibus) Regulation. The amendments have been proposed following extensive discussion between CARB and the Engine Manufacturers Association (EMA) during 2023, which culminated in CARB agreeing to revise its heavy-duty vehicle emission standards to align more closely with U.S. Environmental Protection Agency standards.
U.S. EPA Sets Stricter National Ambient Air Quality Standards for Particulate Matter
On February 7, 2024, the U.S. Environmental Protection Agency (EPA) issued a final rule under the Clean Air Act lowering the primary (health-based) annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter 2.5 micrometers in diameter or smaller (PM2.5) from 12 to 9 micrograms per cubic meter (µg/m3). EPA asserts that the stricter standard is based on scientific evidence showing that the current PM2.5 standard (12 µg/m3), which was established in 2012 and retained in 2020, does not sufficiently protect human health. According to EPA, based on air monitoring data from 2020-22, 119 counties would not meet the new standard of 9 µg/m3.
U.S. Department of Transportation Announces $623M in Grants for Electric Vehicle Infrastructure
On January 11, 2023, the Department of Transportation (DOT) announced $623M in grants to expand electric vehicle (EV) charging infrastructure. The grants are part of the Infrastructure Investment and Jobs Act’s Charging and Fueling Infrastructure Discretionary Grant Program and have been made available to fund 47 EV charging and alternative fueling infrastructure projects in 22 states and Puerto Rico. Ranging from $500,000 to about $68.3M, 36 of the grants were awarded to EV charging and hydrogen fueling “community” projects in rural and urban communities, while the remaining 11 grants were awarded to “corridor” projects focused on fueling along roadways to assist in establishing national EV charging and alternative fueling networks.
U.S. EPA Publishes New Regulations Governing State Plans for Existing Sources of Emissions
On November 9, 2023, the U.S. Environmental Protection Agency (EPA) published implementing regulations that set timelines and other requirements for state plans to limit pollution from existing sources under Clean Air Act (CAA) Section 111. The amended provisions apply to all emissions guidelines published after July 8, 2019, and will affect the scope and pace of development of updated performance standards for existing facilities.
EPA Proposes Stricter Air Pollution Limits on Reclassified Area Sources
On September 21, 2023, the U.S. Environmental Protection Agency (EPA) published a notice of a proposed rule, “Review of Final Rule Reclassification of Major Sources as Area Sources Under Section 112.” The proposal adds requirements for regulated sources of hazardous air pollutants (HAPs) to reclassify from major source status to area source status under the National Emission Standards for Hazardous Air Pollutants (NESHAPs) program. Stakeholders who qualified under the revised policy adopted by the Trump administration should particularly take note of this further change by the Biden administration’s EPA. Comments are due by November 13, 2023.
California Air Resources Board Issues Clean Truck Check Implementation Guidance
On August 23, 2023, the California Air Resources Board (CARB) published additional guidance for the implementation of Clean Truck Check requirements under its Heavy Duty Inspection/Maintenance regulation. The requirements build on implementation guidance issued in June and set deadlines to achieve compliance with certain requirements beginning by December 31, 2023. Fleet owners and operators, and those contracting or brokering loads with heavy-duty trucks, should take note of CARB’s implementation timeline and prepare to comply with reporting and fee payment requirements beginning in the fourth quarter of 2023.
Joint Office of Energy and Transportation Names Electric Vehicle Working Group Members
On August 3, 2023, the Joint Office of Energy and Transportation — created through the Bipartisan Infrastructure Law to facilitate collaboration between the U.S. Departments of Energy (DOE) and Transportation (DOT) — officially announced the members of its Electric Vehicle (EV) Working Group, an independent advisory board. Parties interested in the growth of EVs in the United States should take note of the group, which will coordinate and consult on the development, adoption, and integration of EVs into the transportation and energy systems of the United States.
Regulated Entities in California Communities May Face More Investigation and Enforcement by California Air Resources Board
Regulated entities in designated communities — compiled and termed the “Consistently Nominated AB 617 Communities list” — will want to pay close attention to updates from the California Air Resources Board (CARB) on its Community Protection Program Blueprint 2.0. Currently, communities in the Bay Area, Imperial, San Joaquin Valley, Sacramento Metropolitan, and South Coast air districts are on the list. As part of a mandate to reduce toxic air contaminant and criteria pollutant emissions in communities that have a high cumulative exposure burden, CARB is updating the Program Blueprint 2.0 as required under Assembly Bill 617, adopted by the California Legislature July 26, 2017. CARB’s present revisions may result in increased investigation and enforcement of regulated entities in these communities.
Spring 2023 Agenda Previews Continued U.S. Significant Environmental Regulatory Action
On June 13, 2023, the Biden administration released the 2023 Spring Unified Agenda of Regulatory and Deregulatory Actions (Agenda). The Agenda lists federal agencies’ planned “short-term” regulatory actions to be taken over the next 12 months and “long-term” actions under development. The dates listed in the Agenda are based on publication dates in the Federal Register. Stakeholders should take note, as the Agenda provides a window into the administration’s priorities and strategies:
