The Pennsylvania Department of Environmental Protection announced today that it has submitted its technical guidance for single source determinations for oil and gas operations to the Pennsylvania Bulletin for public comment. The Department's guidance deals with the determination of whether two or more stationary sources should be aggregated together and treated as a single source of air emissions for the purposes of air permitting requirements. Specifically, the guidance involves three sets of regulations: the federal Prevention of Significant Deterioration, or PSD, regulations; the Pennsylvania nonattainment New Source Review regulations; and the Title V program.

The public may comment on the air aggregation determination guidance until November 21, 2011.
