GHG Tailoring Rule

Highlights:

Jan 2, 1011 to June 30, 2011:
Only sources that are major due to emissions of a non-GHG pollutant would be subject to PSD and Title V if their CO2e PTE is 75,000 tpy or more.

July 1, 2011 and on:
Sources would not have to be major for a non-GHG in order to be major due to GHG emissions. The major source threshold for PSD and Title V will be 100,000 tpy CO2e. The major modification threshold for PSD will be 75,000 tpy CO2e.

By July 1, 2012:
EPA will complete rulemaking to address smaller sources of GHGs.

The rule does not provide any BACT guidance, but EPA recognizes the need and is working on it. They plan to issue technical guidance and tools by June 2010 and policy guidance by the end of 2010.
