Although this doesn’t make anything official, it’s an interesting development: the National Association of Clean Air Agencies (NACAA) reported yesterday that, with the onset of greenhouse gas (GHG) permitting only two months away, every state but one -- Texas -- is poised to ensure that sources can obtain preconstruction permits under the Clean Air Act come January 2, 2011.

As we’ve discussed on the blog, certain larger GHG emission sources will be subject to permitting requirements for planned construction projects under the Tailoring Rule starting on January 2, 2011. While most states already have the authority to permit GHGs under preconstruction permit – or Prevention of Significant Deterioration (PSD) – programs, USEPA proposed two rules to fill gaps in 13 state permitting programs that do not allow for the regulation of GHG emissions from industrial sources. The first proposed rule seeks to allow states that are not prepared to regulate GHGs to revise their State Implementation Plans. The second rule outlines USEPA's plan to establish a Federal Implementation Plan that would take over permitting programs in states that do not meet the requirements by January 2011.

NACAA, which is an association of air pollution control agencies in the United States, reviewed the air permitting program responses of the 13 states at issue. According to the NACAA report, air permitting agencies in all states on USEPA’s list (except for Texas) “have indicated that they will either revise their PSD rules by January 2, 2011 or very shortly thereafter, or accept a Federal Implementation Plan (FIP) that will give EPA authority to issue the GHG portion of PSD permits until state rules are revised." This provides some assurance that sources required to apply PSD controls to their GHG emissions will be able to obtain the necessary permits and avoid construction delays.
