Clean Energy Constructed Public Access Station Will Operate 24/7
and Will Be Available to Other Area CNG Vehicles

HARTFORD, Conn. (May 1, 2013) — Clean Energy Fuels Corp. (Nasdaq: CLNE), along with All Waste/USA Hauling and Recycling/All American Waste, leading Connecticut full-service refuse and recycling companies, today welcomed community leaders to the grand opening of their new public access compressed natural gas (CNG) fueling station.

Located at 35 Maxim Road in Hartford, Conn., the public access station will fuel a new fleet of CNG refuse trucks operated by All Waste/USA Hauling and Recycling/All American Waste in addition to supporting other area CNG fleets such as AT&T, Hartford Yellow Cab, Metro Taxi and Greater Hartford Transit District, among others.

Speakers at the event included Pedro E. Segarra, Mayor, City of Hartford; John B. Larson, Member, U.S. House of Representatives; Daniel C. Esty, Commissioner, Connecticut Department of Energy and Environmental Protection (DEEP); Robert A. Norton, Jr., All Waste/USA Hauling and Recycling/All American Waste; and Andrew J. Littlefair, president and CEO, Clean Energy

“Clean Energy commends our joint venture partners here in Hartford—All Waste, USA Hauling and Recycling, and All American Waste—for helping make this new public access CNG fueling station a reality,” said Andrew J. Littlefair, president and CEO of Clean Energy Fuels. “Their new CNG refuse truck fleet is expected to add fuel diversity, curtail harmful emissions, and help reduce America’s dependence on foreign oil. We are committed to working with Connecticut businesses and government officials to expand the state’s CNG station infrastructure, a move that is intended to give consumers the ability to realize the cost savings, reliability and environmental benefits of cleaner, cheaper domestic natural gas.”

Speaking for All Waste, USA Hauling and Recycling, and All American Waste, Norton said, “This project is consistent with our companies’ goals of providing top-quality services and products to customers. Additionally, because it is open to the public, the station will serve to provide a significant portion of the infrastructure to help our state be a leader in the use of cleaner-burning, American-produced natural gas for vehicles.”

DEEP Commissioner Daniel C. Esty said, “A key component of Governor Malloy’s Comprehensive Energy Strategy is to provide a platform for alternative technologies to compete in the marketplace to see which can best serve our needs.  Natural gas as a fuel for vehicles is one promising approach that we are pleased to see rolling out at stations like this.  It offers the triple benefits of reduced costs for fleet operators, reduced consumption of foreign oil and reduced air emissions.”

CNG-powered vehicles onsite for viewing by grand opening event guests included refuse and recycling trucks deployed by All Waste, USA Hauling and Recycling, and All American Waste, as well as an AT&T van, a Yellow Cab taxi, and a Honda Civic NGV.

Natural gas fuel costs up to $1.50 less per gasoline-gallon equivalent than gasoline or diesel based on current market conditions. The use of natural gas fuel not only reduces operating costs for vehicles, but also reduces greenhouse gas emissions up to 30% in light-duty vehicles and up to 23% in medium-to-heavy-duty vehicles. The U.S. Department of Energy reports that 98% of the natural gas consumed in the U.S. is sourced in the U.S. and Canada, making natural gas a secure North American energy choice.
