On April 1, EPA and the National Highway Traffic Safety Administration (NHTSA) released their final Light-Duty Vehicle Greenhouse Gas Emissions Rule.  The rule establishes the firsts standards on greenhouse gas emissions from certain cars and trucks.  By regulating mobile sources under the Clean Air Act, however, the rule will trigger greenhouse gas regulations of stationary sources beginning in January 2011, thereby impacting a wide variety of industries beyond the automotive sector. 

Specifically, the rule may trigger Prevention of Significant Deterioration (PSD) and Title V permitting requirements for millions of stationary sources.  The forthcoming greenhouse gas “Tailoring Rule,” expected to be finalized later this month, will address whether, when and how such sources may be subject to these PSD requirements.  A fact sheet of the final Light-Duty Vehicle Rule can be found here:
