When operators pull oil out of the ground, it often comes up with copious amounts of natural gas. This “associated gas” can be captured and brought to market, creating an additional revenue source for operators. But if no gathering infrastructure or other methods of capture are deployed, operators either vent the gas to the atmosphere or burn it off with controlled flares. Venting results in the release of methane, a powerful greenhouse gas. Flaring results in troublesome emissions as well, including CO2 and hazardous air pollutants.
According to the Wyoming Oil and gas Conservation Commission (WOGCC), Wyoming’s oil and gas operators vented and flared more than five billion cubic feet of natural gas in 2014. Five billion cubic feet of gas that could be sold to generate taxes and royalties, heat homes and power machinery across the country, instead was wasted. Read More
In case you missed it, PBS NewsHour recently took a close look at an issue EDF has been deeply involved in: oil and gas methane emissions.
PBS captured what many across the country have experienced for years – frustration with a significant waste and pollution problem. U.S. oil and gas drillers emit millions of tons of methane into the air every year. This pollution increases global warming and deteriorates air quality. As impacted rancher Don Schreiber in Gobernador, New Mexico told the reporter, the problem is “sobering.” Read More
Wyoming has worked to build a reputation as a leader on strong, sensible requirements to limit air pollution from oil and gas development. The state was among the first to require measures to limit pollution from newly drilled oil and gas wells (so-called “green completions”) and has been diligent in recent years to create one of the nation’s best leak detection and repair programs in the Upper Green River Basin (UGRB), a portion of the state that had been plagued with unhealthy levels of air pollution. Historically, Wyoming hasn’t waited for federal regulations, it has helped blaze the trail and let others follow.
That is what makes the state’s proposal for new statewide oil and gas air quality requirements disappointing. Wyoming is now looking at ways to reduce oil and gas emissions statewide and the state’s Air Quality Advisory Board will consider new requirements at a hearing in Cheyenne tomorrow—but frequent inspections to find and fix leaks are completely absent from the proposal. This is a problem we hope the state will quickly solve. Read More
It’s report card time for air quality in the U.S. and, unfortunately, several western states are getting grades of “needs improvement.” That’s the take-away from the American Lung Association’s (ALA) annual “State of the Air” report released today. When it comes to unhealthy ozone pollution (commonly referred to as “smog”), several western states are simply not making the grade.
Once mainly seen in major urban areas, smog pollution is now becoming more and more of an issue in the rural mountain west. This is bad news for local residents as smog can cause serious health impacts like aggravated asthma, chronic bronchitis, and heart attacks. At times, areas like the Upper Green River Basin in Wyoming have experienced smog levels that rival Los Angeles.
One of the main culprits? Air pollution from oil and gas development. Ozone pollution is created by an interaction between two different sorts of air pollutants, oxides of nitrogen and volatile organic compounds (VOCs). Oil and gas development provides a significant source of both of these air contaminants across many parts of the West. Read More
Long familiar in major urban areas, smog – what we experts call “ground-level ozone” pollution – is quickly becoming a serious problem in the rural mountain west, thanks to rapid expansion in oil and gas development. Smog can cause serious health impacts like aggravated asthma, chronic bronchitis, heart attacks, and even premature death. In areas like the Upper Green River Basin in Wyoming, smog levels have sometimes rivaled those in Los Angeles.
Now, the Environmental Protection Agency and several western states are putting the pieces in place to fix this problem: EPA through proposed revisions to the health-based ozone standard that will better protect people from pollution, and states like Wyoming and Colorado through strong policies that are helping to reduce the sources of ozone pollution in the oil and gas industry.
In official public comments filed this week with EPA, EDF and a broad coalition of western environmental and conservation groups supported a more protective ozone standard and pointed out the importance of this issue to the intermountain west–where most of the country’s oil and gas production from federal lands occurs.
Wyoming has a long history of living with the oil and gas industry that goes back to the nineteenth century, but that doesn’t mean that new drilling projects in new parts of the state don’t get the public’s attention. New neighbors are always a source of local interest and an approach to air quality regulations that includes different requirements for different parts of the state can lead local residents to ask what new oil and gas development will mean for their neighborhoods, for their air, and for their quality of life.
If the robust turnout of several hundred people at two recent public meetings in Laramie and Converse counties is any indication, there is significant interest in how potentially rapid oil and gas development could impact local communities. Read More
