COP26: Biden launches methane-reduction plan, gives flaring a pass
WASHINGTON (Bloomberg) --The Biden administration is launching an assault on methane Tuesday, advancing initiatives across government -- and the globe -- to keep the potent heat-trapping gas from escaping landfills, oil wells and farms.
Measures being announced Tuesday seek to deploy at least five Cabinet-level agencies. For instance, the Environmental Protection Agency is releasing a long-awaited proposal to require leaks in oil and gas wells to be plugged. The Agriculture Department will announce a program encouraging farmers to harness and sell methane. Pipeline regulators will expand their oversight of natural gas lines.
And President Joe Biden, who is in Glasgow, Scotland, for the United Nations COP26 conference on climate change, will also announce that more than 90 nations have signed a joint U.S.-European Union pledge to collectively reduce global methane emissions 30% below 2020 levels by 2030. Brazil, a major source of methane emissions, announced Monday that it was joining the pact.
In Scotland on Monday, Biden called methane cuts the “most effective strategy we have to slow global warming in the near term.”
Methane, the chief component of natural gas, has more than 80 times the atmosphere-warming power of carbon dioxide the first two decades after it is released. Because it packs such a powerful punch in the short term, reductions can yield near-immediate results -- unlike the longer time frame required for the impact of carbon dioxide cuts.
Biden’s campaign, which was described by senior administration officials, is eliciting disappointment from some environmentalists who wanted the administration to go further to plug oil industry leaks. The EPA’s proposed regulation, for example, would still permit flaring of unwanted natural gas from oil wells. And proposed inspection requirements could translate to less frequent checks for small operations.
Rapid advancements in methane detection technology mean more sites can be monitored, said Lauren Pagel, policy director at the environmental group Earthworks. “All communities deserve to breathe cleaner air and no well should be exempt from common-sense pollution standards when we know all wells pollute.”
Another EPA initiative being rolled out Tuesday will seek through voluntary actions to capture 70% of methane from landfills nationwide, said one of the officials, who spoke anonymously before the announcements were public.
The Pipeline and Hazardous Materials Safety Administration is formally expanding the federal government’s oversight to all onshore gas gathering pipelines. The measure will for the first time apply federal pipeline safety regulations to some 425,000 miles of pipelines, where ruptures can have lethal consequences and gush methane into the atmosphere.
Next year, the agency will go further by seeking to regulate some 2.3 million miles of pipelines inside cities that have escaped its oversight and are a major source of methane leaks, a senior administration official said.
The efforts are anchored by an EPA proposal to order more frequent inspections and repairs of methane leaks at oil industry sites, including, for the first time, wells that were drilled before 2015.
“With this historic action, EPA is addressing existing sources from the oil and natural gas industry nationwide, in addition to updating rules for new sources, to ensure robust and lasting cuts in pollution across the country,” EPA Administrator Michael Regan said in a news release.
The measure would require companies to replace leak-prone equipment and more frequently search for leaks at oil and gas sites. States would be asked to develop plans to limit methane emissions from older, existing wells and equipment.
The initiative, if finalized, also would effectively ban routine venting, when natural gas is released unchecked into the atmosphere after emerging from oil wells alongside more profitable crude.
The EPA, however, is stopping short of imposing an outright ban on routine, intentional flaring, when that excess natural gas is burned instead. That’s despite concerns the phenomenon is widespread in West Texas, New Mexico and other drilling hotspots where the construction of gas pipelines hasn’t kept up with crude production. Burning natural gas converts it into carbon dioxide, but when the flares burn incompletely or go out, methane vents directly into the atmosphere.
That omission is set to disappoint activists who lobbied the EPA to follow the lead of some states that have barred flaring.
The EPA requirements also would apply unevenly across the industry, by focusing surveillance efforts on the sites and equipment the agency says are most likely to have large emissions. Under the proposal, well sites with estimated emissions of at least 3 tons per year would have to be monitored quarterly for leaks, with prompt repairs of any that are discovered, according to an EPA official. By contrast, well sites estimated to emit fewer than 3 tons per year could undertake just one survey to demonstrate they are free of leaks or malfunctions.
Although the EPA predicts its approach would focus efforts on the locations responsible for 86% of methane emissions from wells, the determination is based on agency estimates that scientists and activists have widely said underestimate leaks.
