The U.S. Environmental Protection Agency took a big step this week, announcing the nation’s first methane pollution standards for the oil and gas industry. But to understand the impact of these new draft rules, it’s important to look at what they do – and what they don’t – and measure them against the nation’s bold but readily achievable goals set out by the Obama administration earlier this year.

The president’s target of reducing methane emissions by 40 to 45 percent in the next decade is historic – currently there are no national limits on methane pollution from the oil and gas industry. It’s also critical to protecting the climate and public health – methane packs more than 80 times the warming power of carbon dioxide over a 20-year timeframe, and is released along with other toxic pollutants.

The scale of the problem is massive, with industry releasing more than 7 million tons of methane each year. It could also be even bigger than we realize. A new study published just this week reported unrecorded methane emissions from thousands of facilities in only one part of the supply chain. It concluded gathering facility emissions were eight times higher than estimated, a staggering figure that if included in EPA’s inventory would increase current estimates of total industry emissions by 20 percent.

A new study published today reveals that facilities that collect and gather natural gas from well sites across the United States emit about one hundred billion cubic feet of natural gas a year, roughly eight times the previous estimates by the U.S. Environmental Protection Agency for the segment. The wasted gas identified in the study is worth about $300 million, and packs the same 20-year climate impact as 37 coal-fired power plants.

Until now, emissions from thousands of gathering facilities – which consolidate gas from multiple wells in an area and feed it into processing plants or pipelines – have been largely uncounted in federal statistics, yet they may be the largest methane source in the oil and gas supply chain. Indeed, the newly identified emissions from gathering facilities would increase total emissions from the natural gas supply chain in EPA’s current Greenhouse Gas Inventory by approximately 25 percent if added to the tally.

The study was conducted by scientists at Colorado State University and published today in Environmental Science & Technology.

EPA doesn’t track emissions from gathering facilities separately from production activities, and there have been no estimates and almost no research on them until now. One reason prior emissions estimates are so uncertain is because the number of facilities was completely unknown. Without conducting a full census, the CSU researchers were able to put the figure at between 3,846 and 5,470 facilities – a wide range, but far better than the guesswork than existed previously.
