In what it called “the greatest and most consequential day of deregulation in U.S. history,” the Environmental Protection Agency (EPA) announced its most expansive deregulatory initiative to date on March 12, 2025. Through a series of press releases and a public address by Administrator Lee Zeldin, the agency outlined 31 planned actions aimed at rescinding, revising or reconsidering existing environmental rules and policies. Each of the press releases, as well as the underlying regulations at issue, are linked below.
Framed as an effort to advance the goals of President Trump’s Unleashing American Energy Executive Order, the agency seeks to promote cooperative federalism, lower the cost of living, and revitalize the auto and energy industries by decreasing regulatory burdens. These proposed changes span air and water quality standards, energy and manufacturing sector regulations, and enforcement priorities, reflecting a broad shift in federal environmental policy toward deregulation and state-led environmental governance.
Noticeably absent from the 25 press releases issued on March 12 was any reference to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or Superfund reform, or to the EPA’s 2024 rulemakings on per- and polyfluoroalkyl substances (PFAS): the Safe Drinking Water Act maximum contaminant levels (MCLs) and the designation of two PFAS as hazardous substances under CERCLA. The administration recently signaled that it may reconsider last year’s PFAS rules by requesting stays in ongoing litigation challenging each action—suggesting that an announcement by Administrator Zeldin regarding these regulations may be forthcoming.
Overview of the Proposed Actions
The EPA’s 31 proposed deregulatory actions are grouped into three key initiatives outlined by the EPA.
Unleashing American Energy
Under the Unleashing American Energy initiative, the agency aims to reconsider or revise several regulatory frameworks affecting energy production, air and water quality standards, and industrial emissions. Key proposals include:
Lowering the Cost of Living for American Families
As part of its broader deregulatory agenda, the EPA has proposed several actions aimed at reducing regulatory costs that it contends contribute to higher consumer expenses. These initiatives include:
Advancing Cooperative Federalism
The EPA has outlined several deregulatory initiatives aimed at expanding state authority in environmental decision-making. These actions include:
From Proposal to Policy
These proposed regulatory changes will not take effect immediately. Generally, the EPA must follow the federal rulemaking process as outlined in the Administrative Procedure Act (APA). This process includes several key steps:
However, certain rules—even if already in effect—may be subject to recission through a joint resolution of disapproval under the Congressional Review Act (CRA). Generally, the CRA applies to rules submitted to Congress within the previous 60 legislative days. However, the CRA’s “look-back” provision resets the review window if the rule was finalized during the last 60 legislative days of the prior Congress, granting the new Congress a fresh 60-legislative-day period to act.
In the House, CRA resolutions proceed under normal legislative procedures, including committee referral. By contrast, the CRA provides expedited procedures in the Senate, allowing the resolution to avoid a filibuster, proceed to a vote with limited debate (up to 10 hours), and pass by simple majority. If both chambers pass the resolution and the President signs it (or Congress overrides a veto), the rule is retroactively nullified and treated as though it had never taken effect.
The CRA has already been used to rescind a Biden-era EPA rule, with several others under consideration. Two days after the EPA issued its deregulatory press releases, President Trump signed Public Law No. 119-2, a CRA joint resolution of Congress, disapproving of an EPA rule issued last November that established methane emissions charges under the Inflation Reduction Act’s Methane Emissions Reduction Program. The disapproved rule would have imposed annual waste emission charges on petroleum and natural gas facilities exceeding certain methane thresholds and was a key element of the Biden-era climate policy framework. The disapproval process moved quickly: the resolution was introduced in the House on February 4, debated and passed on February 26, received and passed in the Senate on February 27, and signed into law on March 14.
Implications and Next Steps
The EPA’s proposed deregulatory actions will have significant implications for businesses across multiple industries, particularly in the energy, automotive and manufacturing sectors. Companies should evaluate how these regulatory changes may impact their operations, compliance obligations and investment decisions. Engaging in the public comment process provides an opportunity to help shape the final rule and mitigate potential risks.
