EPA’s Historic Deregulation Initiative: Implications and Opportunities to Engage


On March 12, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced that EPA would soon undertake efforts to roll back 31 environmental regulations that cut across industry sectors

These changes present both opportunities and challenges for the regulated community. Most of the rules mentioned are already the subject of ongoing D.C. Circuit litigation or may only be modified through traditional notice-and-comment rulemaking. A few address enforcement and related agency priorities, which may largely be addressed as a matter of agency discretion.

If you have not already done so, now is the time to evaluate your regulatory priorities and make plans to communicate those priorities to EPA through a combination of direct advocacy, industry group commenting or litigation (both challenging or supporting EPA efforts), and legislative engagement. Beveridge & Diamond has advised and represented clients – including in litigation – in virtually all of the rules mentioned in Administrator Zeldin’s March 12 announcement. Please contact the authors of this Alert or your usual Beveridge & Diamond contact to learn more about how we can assist you in achieving your regulatory goals.

Key Areas of Regulatory Reform

EPA’s announcements include a broad suite of deregulatory measures affecting industries across the energy, manufacturing, automotive, and infrastructure sectors. Notable areas of focus include:

Reconsideration: What is Required?

Most of the rules addressed in EPA’s announcement were adopted through notice-and-comment rulemaking procedures and will require a similar rulemaking procedure to rescind or rewrite the rule. Hence, EPA will need to justify its actions by developing technical, economic, and scientific support for its proposals, and it will need to identify legal arguments to justify rescission or rollback, or both. For many of these rules, the task will be complicated by prior EPA factual/technical findings and legal interpretations, and EPA will need to develop a persuasive justification for changing course. If EPA does not thoroughly develop an administrative record supporting its decisions, it risks reversal in court. Potential reductions in staff and financial resources at EPA present opportunities for industry to provide key technical and legal support for the reconsideration proposals. 

Next Steps for Regulated Entities

Beveridge & Diamond has a long-standing track record of advising clients through environmental rulemakings, federal permitting challenges, and litigation (including before numerous federal appellate courts and the U.S. Supreme Court). Our team includes former EPA and Department of Justice officials and other regulatory and litigation strategists who can assist with the following recommended actions.

Given the broad scope of EPA’s deregulation effort, we encourage industry leaders to act now to help shape these regulatory outcomes. We welcome the opportunity to discuss how these changes impact your business and how we can support your strategic response.
