Clean Energy Applauds Newly-Enacted State of Texas Legislation to Increase Natural Gas and Other Alternative Fuel Vehicle Use in Both State and Private Fleets

Business Wire, June 24, 2009

—New Regulations Aim at Curtailing Nitrogen Oxide Diesel Emissions, Improving Air Quality, Lowering Fleet Fuel Costs, and Reducing Dependence on Foreign Oil—

SEAL BEACH, Calif. -- Clean Energy Fuels Corp. (Nasdaq:CLNE) today announced its support for newly approved State of Texas legislation that is targeted to increase the number of alternative fuel vehicles, including natural gas-fueled vehicles, in both state agency and private vehicle fleets.

Providing financial incentives in the form of grant funding, the state’s new Clean Fleet Program —SB1759— encourages private fleet owners to replace their medium-to-heavy-duty diesel vehicles with alternative fueled-models, including those powered by clean, green natural gas.

The Texas Clean Fleet Program, effective Sept. 1, 2009, initially allots $6 million per fiscal year for 2010 and 2011 to fleet owners to help fund their vehicle replacement process. The legislation anticipates extending the program through August 2017, which would represent funding of approximately $48 million over the life of the program if funded at initial levels. The Clean Fleet legislation amends the Texas Emissions Reduction Plan (TERP), enacted in 2001 to improve air quality in Texas. The TERP program is aimed at reducing nitrogen oxide emissions from diesel engines.

Companion legislation — newly-enacted HB 432 — amends the current state’s Fleet Alternative Fuel Program to mandate that 50% of the state’s 27,000 fleet vehicles must use clean alternatives fuels like compressed natural gas (CNG) 80% of the time. The only exceptions are for law enforcement or emergency vehicles, or if an agency demonstrates that it is not cost-effective to meet the requirements. Although state agencies must meet the requirements by September 1, 2010, the legislation will likely be phased-in as diesel and gasoline-powered state fleet vehicles come up for replacement.
