Pennsylvania DEP Releases 2013 Emissions Inventory for Natural Gas Industry

Earlier this week the Pennsylvania Department of Environmental Protection (DEP) released the 2013 air emissions inventory for the natural gas industry.  Operators submit emissions data to DEP on an annual basis.  Compared to 2012, the 2013 inventory includes data from 1,590 additional well sites and 33 additional midstream facilities.  Despite an increase in the number of facilities reporting emissions data, the 2013 inventory shows a decrease in methane and carbon monoxide emissions compared to 2012.  The 2013 inventory also shows increased emissions of nitrogen oxides, particulate matter, sulfur dioxide and volatile organic compounds.
