Eric Waeckerlin counsels clients across the energy, mining, solid and hazardous waste, manufacturing, and industrial sectors on a wide variety of complex environmental, public lands, and natural resources matters. Eric has been at the forefront of emerging legal and regulatory landscapes, with a particular focus on air quality and climate change issues facing conventional and low-carbon energy development.

Eric focuses much of his practice on issues arising under the federal Clean Air Act (CAA) and has substantial experience advising clients on the Resource Conservation and Recovery Act (RCRA), the Clean Water Act (CWA), the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), and the National Environmental Policy Act (NEPA) as well as all delegated state equivalents. Eric is frequently called upon to represent companies in high-stakes federal and state enforcement, policy, and regulatory matters before the EPA, BLM, and state environmental agencies and oil and gas conservation commissions across the Rocky Mountain West.

 

As the energy landscape continues to change, Eric’s practice has evolved to meet his clients’ needs. He frequently counsels clients on domestic and international climate change and methane policy, including the Inflation Reduction Act’s Methane Emissions Reduction Program, CO2 management and capture and reduction strategies, and other issues affecting conventional and clean energy projects. In his litigation practice, Eric has served as lead counsel for national oil and gas trade associations in challenges to federal regulations. He has also defended oil and natural gas companies in multimillion dollar air quality enforcement actions brought by the EPA and related state agencies.

On March 12, 2025, EPA Administrator Lee Zeldin announced the agency’s intention to reconsider 31 environmental regulations, describing the effort as the “single most impactful day of deregulation in EPA history.” While the scope of this initiative spans air, water, and climate regulations, the most consequential actions—legally and practically—center on a handful of cross-cutting programs and sector-specific rules.
