WASHINGTON (AP) — With two months left in President Barack Obama’s term, his administration issued a rule Tuesday intended to clamp down on oil companies that burn off natural gas on public lands.
The new rule seeks to reduce waste and harmful methane emissions as part of a strategy to address climate change. But a new Republican administration under President-elect Donald Trump could reconsider the rule or even scrap it, although any effort to do so would likely take months.
Trump has said he will seek to sharply increase oil and gas drilling on federal lands and said on the campaign trail that restrictions supported by Obama and Democratic presidential candidate Hillary Clinton would hurt energy-producing states such as Colorado.
Energy companies frequently “flare” or burn off vast supplies of natural gas at drilling sites because it makes less money than oil. A government report said an estimated 40 percent of the gas being flared or vented could be captured economically and sold.
Interior Secretary Sally Jewell said the new rule updates 30-year-old drilling regulations to meet modern standards and ensure that natural gas is used to power the economy — not wasted by being burned into the atmosphere.
“This rule to prevent waste of our nation’s natural gas supplies is good government, plain and simple,” Jewell said in a statement. “We are proving that we can cut harmful methane emissions that contribute to climate change, while putting in place standards that make good economic sense for the nation.”
Under the new rule, drilling companies will be required to capture natural gas that can be used to generate power for millions of homes and businesses, Jewell said. Between 2009 and 2014, enough natural gas was lost through venting, flaring and leaks to power more than 5 million homes for a year, she said.
The new rule also should generate millions of dollars that can be returned to taxpayers, tribes and states while reducing pollution, Jewell said.
The rule, developed by Interior’s Bureau of Land Management, will require oil and gas producers to limit the rate of flaring at oil wells on public and tribal lands, periodically inspect their operations for leaks and replace outdated equipment that vents large quantities of gas into the air.
Most of the gas being burned at drilling sites is methane, a powerful greenhouse gas that is about 25 times more potent at trapping heat than carbon dioxide, although it does not stay in the air as long. Methane emissions make up about 9 percent of U.S. greenhouse gas emissions, according to government estimates.
The oil industry has argued that new regulations are not needed for methane because the industry already has a financial incentive to capture and sell natural gas. Methane emissions have been reduced by 21 percent since 1990 even as production has boomed, according to the Western Energy Alliance, an industry group.
The energy alliance, along with a group representing independent petroleum producers, challenged the rule in federal court in Wyoming, saying the rule goes beyond authority granted by Congress.
“We support the goals of capturing greater quantities of associated gas and reducing waste gas, but overreaching regulation that fails to acknowledge industry success is not the most effective way to meet those goals,” said Kathleen Sgamma, a spokeswoman at the Denver-based energy alliance.
