Pennsylvania has more than 400 compressor stations, including older stations that handle natural gas produced from conventional wells.
DEP has been criticized by environmental groups over rules that govern when it treats compressor stations as individual, minor sources of pollution and when it groups them together with related natural gas facilities like wells and pipelines, for purposes of aggregating their air emissions. Major sources of pollution are subject to stricter controls.
State Rep. Jesse White, a Democrat from Washington County, said Thursday's announcement "totally ignores the real problem, which is that DEP refuses to aggregate emissions results. So if there are 10 compressors right next to one another, DEP monitors emissions of each one separately, even though the combined emissions of all 10 are coming in through your kitchen window."
Krancer has called the aggregation rules a "practical, common-sense and legally sound approach" used by many other oil- and gas-producing states.
