===June 2010: Somerset County Spill===
One of the largest single-incident fines in the [[Marcellus Shale]] stemmed from an incident that began on June 10, 2010, at a Marcellus well site on a dairy farm in Somerset County. The Pittsburgh Post-Gazette reported that state inspector, April Weiland, determined that it appeared that Chief Oil & Gas had “intentionally buried” the spill with soil and rock. Chief Oil & Gas denies hiding spill and the company was fined $180,000, one of the largest single-incident fines in the [[Marcellus Shale]].<ref>[http://www.post-gazette.com/news/state/2014/08/03/Drillers-did-not-report-half-of-spills-that-led-to-fines/stories/201408020142 "Drillers did not report half of spills that led to fines"] Sean D.
