Summary

On Wednesday, October 12, 2011, PA DEP issued technical guidance for "Performing Single Stationary Source Determinations for Oil and Gas Industries." The public comment period will close Nov. 21. The technical guidance and fact sheet are below. Summary: Single Stationary Source Determinations for Oil and Gas Industries - There are significant gas exploration and extraction activities occurring in the commonwealth within the Marcellus Shale and other formations. As a result, there are permitting issues related to whether the air emissions from exploration, extraction or production activities should be aggregated, or combined, to determine whether the emissions from these stationary sources constitute a "major stationary source" or "major facility" for purposes of the Prevention of Significant Deterioration (PSD), Pennsylvania nonattainment New Source Review (NSR) and Title V permitting programs. DEP's interim final technical guidance for performing single stationary source determinations for Oil and Gas industries is meant to provide guidance to permitting staff in making these determinations. What is a Single Source Determination? Single source determinations for oil and gas operations are conducted by air quality permitting authorities to determine if multiple stationary contamination sources should be treated as separate sources or as a single source. If the aggregated emissions from two or more air contamination sources reach major source applicability thresholds, they would be subject to additional air quality permitting requirements under the PSD, Pennsylvania nonattainment NSR and the Title V permitting programs if the sources meet certain regulatory criteria.
