Dramatic ozone spikes puzzle regulators, locals in Wyoming gas field

 “You need the right mix of factors to create ground-level ozone: sunlight, snow cover, little to no wind and, of course, emissions from the oil and gas industry. Breathing it in can cause a variety of health problems, from chest pain to reduced lung function. Friday was the 12th ozone action day of the season. It’s a record number for recent years.”

Air quality appeal targets ‘NPL’ field
By Mike Koshmrl. Sep 30, 2018
Jackson Hole Daily
“Even though it’s a rural area, this is big-city air pollution that they are experiencing.” An air monitoring station registered a dozen ozone exceedance days in 2017. The BLM considered, but “eliminated from further analysis,” a drilling plan that would have resulted in no net increase in emissions.

Driven by Trump Policy Changes, Fracking Booms on Public Lands
By Eric Lipton and Hiroko Tabuchi. Oct. 27, 2018.
The New York Times
“The administration is auctioning off millions of acres of drilling rights and rolling back regulations, raising environmental concerns in states like Wyoming. Through July, energy companies had flared or vented 72 percent more methane in Wyoming compared with two years ago.”

Interior Could Do More to Account for and Manage Natural Gas Emissions
United States Government Accountability Office, July 2016
“Interior may not have a consistent accounting of natural gas emissions from onshore federal leases, and does not have the information it needs to reasonably ensure it is minimizing waste on these leases.
The Bureau of Land Management’s (BLM) field offices have not consistently followed BLM’s existing guidance in managing operators’ venting or flaring requests.”

Field working to find quality solution
By Noah Brenner. March 22, 2013
Upstream
“Rob Field is among researchers at the University of Wyoming driving thousands of miles through the Pinedale Anticline natural gas field to find out why a big-city pollutant is appearing outside Pinedale, Wyoming, which has a population of 2030.  As the massive Pinedale Anticline and Jonah natural gas fields drew dozens of rigs into Sublette County, Wyoming, air quality in the basin deteriorated in the winter months until, in 2011, monitors measured upwards of 11 instances where ozone levels were so high that people were warned not to go outside.”
