We’ve reported several times on the emergence of alleged air contamination issues relating to E&P operations, primarily out of the southwest and U.S. EPA.  Not surprisingly, the claim has come to the Appalachian Basin.  The Pennsylvania Department of Environmental Protection (DEP) has released a report on a short term air quality study conducted near Marcellus Shale natural gas operations in southwestern Pennsylvania.  According to DEP Secretary John Hanger, "The data shows no emission levels that would constitute a concern to the health of residents living near these operations."  (Emphasis is ours.)
