EPA Moves to Roll Back Methane Leak Rules for Oil and Gas Operations
The Trump administration was expected to announce plans to weaken rules guarding against methane leaks from oil and gas operations, with the announcement reportedly set for a campaign rally in Lubbock, Texas. The Verge reported the timing on October 27, 2026.
The EPA planned to undo Biden-era methane rules that were expected to cut methane emissions by 80 percent over 14 years. The standards were issued under the 2023 final rule, which sharply reduced emissions of methane and other harmful air pollutants from oil and natural gas operations. They sit alongside the Methane Emissions Reduction Program that Congress created under the Inflation Reduction Act of 2022.
EPA Administrator Lee Zeldin said the rollback would save oil and gas companies $45 billion. He also said the previous methane rules would have incurred $18 billion in regulatory costs. The two figures come from the same official and the same rulemaking, but they describe different things: one is a projected saving from the proposed rollback, the other a projected cost of the existing rules.
The sequence of announcements has been visible for several weeks. In an October 7 press release, the EPA said it was days away from proposing the oil and gas rule change. Zeldin described the forthcoming action as a proposal for the second part of the agency's oil and gas reconsideration, which suggests the agency is working through the 2023 framework in stages rather than in one package. Reuters reported at the time that methane is the second-biggest cause of climate change after carbon dioxide.
The proposal was expected to go beyond the headline rules in two areas. It would step back standards for marginal wells, which are older wells that produce little fuel. It would also end the Super Emitter Program, which used outside groups to report large methane releases and notified operators of releases of 100 kilograms per hour or more. Reuters described the program as the mechanism through which those outside reports reached the companies in question. Marginal wells make up a large share of the country's operating wells, so that change touches far more sites than the Super Emitter change, even though the latter targets the largest individual releases.
The EPA has also published its own cost estimate for a separate 2026 final rule intended to reduce regulatory burden on the sector. That estimate puts industry savings at $2.5 billion from 2024 to 2038 at a 3 percent discount rate, or $208 million per year. A discount rate lowers the present value of money saved in future years, so the choice of rate changes the total. Set beside Zeldin's $45 billion figure, the gap shows how sensitive these numbers are to scope, time horizon and discounting. Savings claimed for one rule, savings claimed for another and avoided costs of prior rules are not directly comparable without the underlying assumptions.
In my view, the most useful question for engineers and compliance teams is not which headline number is correct but which measurement regime survives. Leak detection under the Super Emitter model relied on third-party reporting, and removing it shifts the burden back toward operators' own monitoring and the agency's enforcement capacity. Whether that produces leaner compliance or a thinner detection layer will depend on the specifics of the proposal, which had not yet been published at the time of these reports.
The broader context here is that methane detection has become as much an instrumentation problem as a regulatory one. Continuous monitoring, satellite-based detection and operator-side sensing have all matured over the past several years. If the rules change the economics of who looks for leaks and how often, the technology to find them is already in the field. The open question is how that work gets funded and whether it is required.
