The Pennsylvania Department of Environmental Protection announced on October 12, 2011, that it has submitted technical guidance for air aggregation determinations to the Pennsylvania Bulletin to receive public comment. These guidelines are used to determine whether multiple air emission sources should be aggregated and treated as a single source for permitting purposes. According to the DEP press release, the new determinations will treat air emissions sources located a quarter mile apart as contiguous or adjacent. The public comment period will close November 21, however the Air Quality permitting staff will begin implementing the guidelines on an interim basis.
