Dear Administrator Jackson:

The State of California’s Air Resources Bo ard (ARB) strongly supports the recently

announced United States Environmental Pr otection Agency (U.S. EPA) and National Highway Traffic Safety Admi nistration (NHTSA) proposed nat ional program to reducegreenhouse gas (GHG) emissions and improve fuel efficiency of medium- and heavyduty vehicles. Continued, unwavering progre ss along this regulatory path is vital for

California and the nation as we continue to strive to stabilize the climate and address the threat of global climate change.

California appreciates your staff’s engagem ent with ARB to date and understands that this program would result in the introducti on of the most GHG- efficient medium- and heavy-duty vehicles on the road, encour aging technology innovation and early introduction. California fully supports the deve lopment of such national regulations, as it will help us meet the goals established by t he California Global Warming Solutions Act of 2006 (AB 32). Specifically, AB 32 m andates a reduction of California's GHG emissions to 1990 levels by 2020 and the Governor has ordered an 80 percent

reduction from 1990 leve ls by 2050.

In order to meet t hese aggressive goals, California has already taken action. In December 2008, ARB adopted the Heavy-Du ty Vehicle Greenhouse Gas Emission Reduction Regulation requiring the use of U.S. EPA SmartWay certified heavy-duty

tractor trailer combinations in California. While California is committed to the success of our program, we are encouraged and have welcomed the opportunity to partner with

U.S. EPA and NHTSA on a national program.Honorable Lisa P. Jackson, Administrator October 26, 2010 Page 2

Such a partnership would better achiev e our shared goals and provide national consistency for the regulated co mmunity. We look forward to continuing our work with U.S. EPA and NHTSA on this program. Shoul d you have any questions, please contact Mr. James Goldstene, Executive Officer, at (916) 445-4383 or at jgoldste@arb.ca.gov

Sincerely,

Mary D. Nichols
