: Air emissions case study related to oil and gas development in Erie, Colorado; From late July to late August 2012, the Colorado, "December 5, 2012." -- Cover., "October 16, 2014." -- Page 48., In October 2014, Addendum to Air emissions case study related to oil and gas development in Erie, Colorado for correction of incorrect methane data, was created and appended to the original document 2012 study. Pagination is consecutive throughout. Air Pollution Control Division, conducted air sampling adjacent to natural gas well completion activities in Erie, Colorado. The purpose of the sampling was to measure air emissions that may be associated with the well completion activities. The air sampling results are consistent with what would be expected. Concentrations of likely oil and gas related compounds such as ethane and propane were found to be slightly higher at the Erie sites than in downtown Denver, but much lower than in Platteville where greater oil and gas activity is taking place. Similarly, methane levels at the Erie sites were consistent with other locations, and were higher than in Denver, and lower than in Platteville. Toluene and benzene levels were higher at one Erie monitor than the other, likely due to emissions from truck traffic., Online resource; title from PDF cover (viewed April 2023)
