Study finds Pennsylvania drillers have reduced errors
(Bloomberg; May 15) - Natural gas drillers in Pennsylvania's Marcellus Shale have reduced the rate of blowouts, spills and water contamination by half since 2008, according to a study of state-agency actions. State regulators issued environmental violations at 27 percent of the wells drilled in the first eight months of 2011 - 54 percent below the full-year rate in 2008, according to the study by New York's University at Buffalo's Shale Resources and Society Institute.
Stronger regulations, tougher enforcement and improved industry practices helped trim the violations, researchers found. "The odds of non-major environmental events and the much smaller odds of major environmental events are being reduced even further by enhanced regulation and improved industry practice," according to the study.
