Wrong time to backtrack on ozone, other air protections, by Elaine Crumpley, April, 2017 (Wyofile)

In November of 2016, The Bureau of Land Management (BLM) published its final rule that intended to limit the loss of methane through venting, flaring or leaks of natural gas from oil and gas production on public and Indian lands. Some provisions were to go into effect in January 2017 and others in January 2018. The BLM’s new rule postpones those provisions and suspends others already in effect until January 17, 2019. It will mean another year where taxpayers lose out on significant royalties from natural gas waste.

Designed to reduce natural gas waste, this rule would also achieve lower greenhouse gas emissions from oil and gas production, while providing “a fair return on public resources for federal taxpayers” by requiring operators to pay royalties on wasted gas. The BLM estimates the rule could save enough methane to supply around 740,000 households each year.

By January 2019 deadline, the BLM intends to make substantial changes to the 2016 methane rule, curtailing its ability to reduce wasteful production practices on federal lands. Read full article

Study links Wyoming winter ozone to drillers’ wastewater plant, April, 2015 (WyoFile).

Emissions from wastewater recycling at oil and gas drilling sites likely contributed to a string of high-ozone events in the winter of 2011 in Wyoming’s Upper Green River Basin, according to a study released this week. By studying the chemical signatures in emissions from oil and gas operations, the study, led by researchers at the University of Wyoming, found that wastewater treatment was a major source of non-methane pollutants that spurred ozone formation.

Regulators back smog rules for Sublette area, December, 2014 (Wyofile)

The Wyoming Air Quality Advisory Board voted unanimously Wednesday to back regulations limiting emissions at existing oil and gas facilities in the Pinedale area where smog has violated federal standards. Following a full morning of comments, including calls for a number of changes proposed by the Petroleum Association of Wyoming and other industry voices, the five-member appointed board wasted little time. The board swiftly recommended approval of the rules to limit ozone pollution, saying late-arriving technical comments could be addressed when the Environmental Quality Council considers the regulation’s final adoption. Read full article

Wyoming deploys strategy to battle ozone, March, 2013 (Wyofile)

The Wyoming Department of Environmental Quality on Thursday made public its Ozone Strategy, a requirement of the federal “non-attainment” designation applied to the Sublette County area due to multiple wintertime ozone events that threatened human health. Read full article

Wyoming’s winter ozone in check, so far, February 2012 (Wyofile)

“The highest values are occurring at the Boulder monitor, however, the Juel Springs, Daniel, and Big Piney monitors have also recorded slightly elevated ozone this year,” Keslar said. “It should be noted that these values have not gone through the data validation process yet, however, all stations have undergone independent quality assurance audits for this quarter and have passed.” Read full article

Ozone Dilemma continues in Pinedale, Wyoming Outdoor Council, September, 2011Earlier this year, the ozone level in Wyoming’s once pristine Upper Green River Basin spiked beyond Los Angeles’ worst smog day. Thirteen high-ozone events this past winter from oil and gas activities in the region resulted in 10 state-issued warnings to remain indoors. Read full article

Ozone spikes aren’t Mother Nature’s fault,  April 2011 (WyoFile)

“From my perspective as governor, you know, I do not like hearing, in Pinedale Wyoming, an advisory that says keep your young kids in the house. If we lived in Los Angeles, maybe that’s an everyday occurrence. But if you live in Pinedale Wyoming — or frankly, anywhere in Wyoming where we tout our air quality — you don’t want to hear that,” Gov. Matt Mead said during a press conference on Tuesday.” Read full article

Pristine to Polluted, WyoFile, May 2011

“State, federal and company officials admit they don’t fully understand how to restore air quality and avoid further exceedences of federal Clean Air Act standards in the once-pristine airshed of the Upper Green River Basin.” Read full article
