Sharp Budget Knife at Throat of SRFs

April 2011 Vol. 66 No. 4

The EPA's initial GHG regulation took effect in January 2011 when it issued a final rule requiring "major sources" of air toxics to apply for a permit when their emissions crossed the threshold of 25 metric tons on Jan. 1 because of the addition of GHG emissions, which were previously not computed in a program called "prevention of significant deterioration (PSD)." This could apply to gas transmission pipelines based on GHG emissions from compressions stations and vents.
