The U.S. Environmental Protection Agency (EPA) has finalized regulations impacting a large swath of refrigeration and cooling equipment industries. The new regulations are the most recent EPA action addressing the use of hydrofluorocarbons (HFCs), greenhouse gases often used to replace ozone-depleting substances for refrigeration and cooling, under the American Innovation and Manufacturing Act of 2020 (AIM Act). This latest set of AIM Act regulations imposes new requirements to reduce HFC emissions and create a new reclamation program. The rule will impact a wide variety of refrigeration and cooling equipment supply chains, including those that own, operate, install, service, and repair equipment containing HFCs, as well as those that recover, recycle, or reclaim HFCs or their substitutes. Together, the new regulations establish EPA’s Emission Reduction and Reclamation (ER&R) Program. Entities that are potentially impacted by the new rule will need to review the requirements carefully as they vary by industry and application.Continue Reading EPA’s Newest Emission Reduction and Reclamation Program Breaks Refrigerants and Cooling Status Quo

On March 11, the U.S. Environmental Protection Agency (EPA) published the long-awaited Safer Communities by Chemical Accident Prevention Rule (Final Rule), which concluded a nearly decadelong process — spanning three administrations — to update EPA’s Risk Management Program (RMP) under the Clean Air Act (CAA).Continue Reading EPA Makes Major Changes to Risk Management Program Under Clean Air Act

The U.S. Securities and Exchange Commission (SEC) has issued its long-awaited climate reporting requirements, making it mandatory for the largest publicly traded companies in the U.S. to annually disclose both greenhouse gas (GHG) emissions and their material climate risks, with some requirements kicking in as early as 2025. On March 6, the SEC voted 3-2 along party lines to pass a pared down version of its March 2022 proposal, giving regulated companies the final word on the much-anticipated rule.Continue Reading SEC Issues Final Climate Disclosure Rules, Paring Down Its 2022 Proposal, With Implications for Greenwashing Claims

Exercising one of its most important and far-reaching powers under the Clean Air Act, the Environmental Protection Agency (EPA) has lowered the primary annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM2.5) from 12 micrograms per cubic meter (ug/m3) down to 9 ug/m3, changing the game on air quality permitting for much of the U.S. EPA’s February 7, 2024 final rule, which will become effective 60 days following its publication in the Federal Register, represents a reversal of the Trump administration’s decision to retain the PM2.5 standard of 12 ug/m3 set under the Obama administration in 2012. The lower standard will set off a chain reaction of additional requirements for state air agencies, and ultimately industrial sources, in places designated as nonattainment with the new standard, but one impact of the new standard will be felt almost immediately: increased difficulty in obtaining air permits.Continue Reading EPA Lowers Annual PM2.5 NAAQS, With Immediate Impacts for Air Permitting

For anyone involved in the first round of the Clean Air Act regional haze program, the U.S. Environmental Protection Agency’s (EPA) action on the first business day of 2024 came as no surprise: EPA proposed to disapprove the regional haze plan for Kansas. If the past is any indication of the future, this proposal foreshadows what will likely be many more regional haze state plan disapprovals over the next 12 months, given that EPA has already been hauled into court once again to force it back on schedule.Continue Reading And so It Begins…EPA Issues First Disapproval of Regional Haze Round Two

On October 7, 2023, California Governor Newsom signed two landmark bills into law, Senate Bill (SB) 253 and SB-261, imposing new requirements on large companies doing business in California to publicly report their annual greenhouse gas (GHG) emissions and climate-related risks. These laws apply to both publicly traded and privately held companies, exceeding the scope of the climate disclosure rule proposed by the U.S. Securities and Exchange Commission (SEC) in March 2022. Our professionals have prepared a more detailed summary here; some key highlights are included below.Continue Reading California Adopts Landmark GHG Emissions and Climate Risk Reporting Laws

On August 7, Nebraska Attorney General (AG) Mike Hilgers and Iowa AG Brenna Bird joined forces to sue the Biden administration’s Environmental Protection Agency (EPA) for failing to fulfill the request by Iowa and Nebraska governors to allow the sale of year-round E15 gasoline.Continue Reading Nebraska and Iowa AGs Sue Biden Administration’s EPA for Failing to Fulfill Sale of Year-Round E15 Gasoline

EPA’s long-promised rules for reducing CO2 emissions from fossil fuel-fired power plants have now been published. In the proposal, EPA lays out “performance standards” for new natural gas-fired power plants and “emission guidelines” for states to use in developing standards for existing gas- and coal-fired power plants.Continue Reading EPA’s New Carbon Standards for Power Plants Require Quick Decisions

On January 9, the White House Council on Environmental Quality (CEQ) issued an Interim Guidance on Consideration of Greenhouse Gas (GHG) Emissions and Climate Change (Interim Guidance) “to assist Federal agencies in their consideration of the effects of GHG emissions and climate change when evaluating proposed major Federal actions in accordance with the National Environmental Policy Act (NEPA).”Continue Reading CEQ issues Notice of Interim Guidance on Greenhouse Gas Emissions in NEPA Reviews
