EPA sets out rules for proposed 'methane fee' for waste generated by oil and natural gas companies

Oil and natural gas companies for the first time would have to pay a fee for methane emissions that exceed certain levels under a rule proposed Friday by the Biden administration.

The proposed Environmental Protection Agency rule follows through on a directive from Congress included in the 2022 climate law. The new fee is intended to encourage industry to adopt best practices that reduce emissions of methane and thereby avoid paying.

Methane is a climate “super pollutant” that is more potent in the short term than carbon dioxide and is responsible for about one-third of greenhouse gas emissions. The oil and natural gas sector is the largest industrial source of methane emissions in the United States, and advocates say reduction of methane emissions is an important way to slow climate change.

Excess methane produced this year would result in a fee of $900 per ton, with fees rising to $1,500 per ton by 2026.

EPA Administrator Michael Regan said the proposed fee would work in tandem with a final rule on methane emissions EPA announced last month. The fee, formally known as the Methane Emissions Reduction Program, will encourage early deployment of available technologies to reduce methane emissions and other harmful air pollutants before the new standards take effect, he said.

The rule announced in December includes a two-year phase-in period for companies to eliminate routine flaring of natural gas from new oil wells.

“EPA is delivering on a comprehensive strategy to reduce wasteful methane emissions that endanger communities and fuel the climate crisis,” Regan said in a statement. When finalized later this year, the proposed methane fee will set technology standards that will “incentivize industry innovation'' and spur action to reduce pollution, he said.

Leading oil and gas companies already meet or exceed performance levels set by Congress under the climate law, meaning they will not have to pay the proposed fee, Regan and other officials said.

Sen. Tom Carper, chairman of the Senate Environment and Public Works Committee, said he was pleased the administration was moving forward with the methane fee as directed by Congress.

“We know methane is over 80 times more potent than carbon dioxide at trapping heat in our atmosphere in the short term,'' said Carper, D-Del. He said the program "will incentivize producers to cut wasteful and excessive methane emissions during oil and gas production.”

New Jersey Rep. Frank Pallone, the top Democrat on the House Energy and Commerce Committee, said oil and gas companies have long calculated that it's cheaper to waste methane through flaring and other techniques than to make necessary upgrades to prevent leaks.

“Wasted methane never makes its way to consumers, but they are nevertheless stuck with the bill,” Pallone said. The proposed methane fee “will ensure consumers no longer pay for wasted energy or the harm its emissions can cause.''

Republicans call the methane fee a tax that could raise the price of natural gas. “This proposal means increased costs for employers and higher energy bills for millions of Americans,” said Sen. Shelley Moore Capito, R-West Virginia.

The American Petroleum Institute, the oil and gas industry's largest lobbying group, slammed the proposal Friday and called for Congress to repeal it.

“As the world looks to U.S. energy producers to provide stability in an increasingly unstable world, this punitive tax increase is a serious misstep that undermines America’s energy advantage,'' said Dustin Meyer, API's senior vice president of policy, economics and regulatory affairs.

While the group supports “smart” federal methane regulation, the EPA proposal “creates an incoherent, confusing regulatory regime that will only stifle innovation and undermine our ability to meet rising energy demand,'' Meyer said. “We look forward to working with Congress to repeal the IRA’s misguided new tax on American energy.”

Fred Krupp, president of the Environmental Defense Fund, called the proposed fee "common sense,'' adding that oil and gas companies should be held accountable for methane pollution, a primary source of global warming.

In a related development, EPA said it is working with industry and others to improve how methane emissions are reported, citing numerous studies showing that and oil and gas companies have significantly underreported their methane emissions to the EPA under the agency's Greenhouse Gas Reporting Program.

The climate law, formally known as the Inflation Reduction Act, established a waste-emissions charge for methane from oil and gas facilities that report emissions of more than 25,000 metric tons of carbon dioxide equivalent per year to the EPA. The proposal announced Friday sets out details of how the fee will be implemented, including how exemptions will be applied.

The agency said it expects that over time, fewer oil and gas sites will be charged as they reduce their emissions in compliance with the rule.

A View From HETI

Corrosion under insulation (CUI) accounts for roughly 60% of pipeline leaks in the U.S. oil and gas sector. Yet many operators still rely on outdated inspection methods that are slow, risky, and economically unsustainable.

This year, widespread budget cuts and layoffs across the sector are forcing refineries to do more with less. Efficiency is no longer a goal; it’s a mandate. The challenge: how to maintain safety and reliability without overextending resources?

Fortunately, a new generation of technologies is gaining traction in the oil and gas industry, offering operators faster, safer, and more cost-effective ways to identify and mitigate CUI.

Hidden cost of corrosion

Corrosion is a pervasive threat, with CUI posing the greatest risk to refinery operations. Insulation conceals damage until it becomes severe, making detection difficult and ultimately leading to failure. NACE International estimates the annual cost of corrosion in the U.S. at $276 billion.

Compounding the issue is aging infrastructure: roughly half of the nation’s 2.6 million miles of pipeline are over 50 years old. Aging infrastructure increases the urgency and the cost of inspections.

So, the question is: Are we at a breaking point or an inflection point? The answer depends largely on how quickly the industry can move beyond inspection methods that no longer match today's operational or economic realities.

Legacy methods such as insulation stripping, scaffolding, and manual NDT are slow, hazardous, and offer incomplete coverage. With maintenance budgets tightening, these methods are no longer viable.

Why traditional inspection falls short

Without question, what worked 50 years ago no longer works today. Traditional inspection methods are slow, siloed, and dangerously incomplete.

Insulation removal:

  • Disruptive and expensive.
  • Labor-intensive and time-consuming, with a high risk of process upsets and insulation damage.
  • Limited coverage. Often targets a small percentage of piping, leaving large areas unchecked.
  • Health risks: Exposes workers to hazardous materials such as asbestos or fiberglass.

Rope access and scaffolding:

  • Safety hazards. Falls from height remain a leading cause of injury.
  • Restricted time and access. Weather, fatigue, and complex layouts limit coverage and effectiveness.
  • High coordination costs. Multiple contractors, complex scheduling, and oversight, which require continuous monitoring, documentation, and compliance assurance across vendors and protocols drive up costs.

Spot checks:

  • Low detection probability. Random sampling often fails to detect localized corrosion.
  • Data gaps. Paper records and inconsistent methods hinder lifecycle asset planning.
  • Reactive, not proactive: Problems are often discovered late after damage has already occurred.

A smarter way forward

While traditional NDT methods for CUI like Pulsed Eddy Current (PEC) and Real-Time Radiography (RTR) remain valuable, the addition of robotic systems, sensors, and AI are transforming CUI inspection.

Robotic systems, sensors, and AI are reshaping how CUI inspections are conducted, reducing reliance on manual labor and enabling broader, data-rich asset visibility for better planning and decision-making.

ARIX Technologies, for example, introduced pipe-climbing robotic systems capable of full-coverage inspections of insulated pipes without the need for insulation removal. Venus, ARIX’s pipe-climbing robot, delivers full 360° CUI data across both vertical and horizontal pipe circuits — without magnets, scaffolding, or insulation removal. It captures high-resolution visuals and Pulsed Eddy Current (PEC) data simultaneously, allowing operators to review inspection video and analyze corrosion insights in one integrated workflow. This streamlines data collection, speeds up analysis, and keeps personnel out of hazardous zones — making inspections faster, safer, and far more actionable.

These integrated technology platforms are driving measurable gains:

  • Autonomous grid scanning: Delivers structured, repeatable coverage across pipe surfaces for greater inspection consistency.
  • Integrated inspection portal: Combines PEC, RTR, and video into a unified 3D visualization, streamlining analysis across inspection teams.
  • Actionable insights: Enables more confident planning and risk forecasting through digital, shareable data—not siloed or static.

Real-world results

Petromax Refining adopted ARIX’s robotic inspection systems to modernize its CUI inspections, and its results were substantial and measurable:

  • Inspection time dropped from nine months to 39 days.
  • Costs were cut by 63% compared to traditional methods.
  • Scaffolding was minimized 99%, reducing hazardous risks and labor demands.
  • Data accuracy improved, supporting more innovative maintenance planning.

Why the time is now

Energy operators face mounting pressure from all sides: aging infrastructure, constrained budgets, rising safety risks, and growing ESG expectations.

In the U.S., downstream operators are increasingly piloting drone and crawler solutions to automate inspection rounds in refineries, tank farms, and pipelines. Over 92% of oil and gas companies report that they are investing in AI or robotic technologies or have plans to invest soon to modernize operations.

The tools are here. The data is here. Smarter inspection is no longer aspirational — it’s operational. The case has been made. Petromax and others are showing what’s possible. Smarter inspection is no longer a leap but a step forward.
