Greenhouse Gas (GHG) Permitting
On June 3, 2010, EPA published the final GHG Tailoring Rule, which specifies that beginning in 2011, projects that will increase GHG emissions substantially will require an air permit.  EPA's update to the GHG Tailoring Rule, issued on June 29, 2012, made no changes to the initial GHG Tailoring Rule thresholds.
Effective January 2, 2011, certain Connecticut permit applicants and DEEP are required to consider greenhouse gas (GHG) emissions in permits issued under both the new source review (NSR) prevention of significant deterioration (PSD) and Title V programs.
