Republic Wins Three of Eight Awards

HALF MOON BAY, Calif.—January 12, 2010— The U.S. Environmental Protection Agency’s (EPA) Landfill Methane Outreach Program (LMOP) selected the Republic Services (NYSE:RSG) Ox Mountain landfill gas-to-energy project (LFGTE) as a LFGTE Project of the Year for 2009. Republic’s Jefferson City Landfill in Jefferson City, Missouri and Oak Grove Landfill in Winder, Georgia also were honored today at the annual LMOP conference in Baltimore. EPA honored a total of eight projects.

Each year, EPA recognizes the latest accomplishments of landfill methane projects that have reduced emissions of methane and created renewable energy. LMOP acknowledges the projects for excellence in innovation and creativity, success in promoting project development, and achieving environmental and economic benefits.

“We are honored that this project has been recognized as beneficial to the environment and the community,” said Jeff Andrews, senior vice president West Region, Republic Services. “It is one of our many renewable energy solutions at landfills that align with our overall environmental commitments.”

The landfill gas-to-energy plant, owned and operated by a subsidiary of Ameresco, Inc., the nation’s largest independent energy services company, will supply enough renewable energy to customers in Alameda and Palo Alto to power more than 11,900 average-sized homes.

The annual electricity generated by the Ox Mountain project will prevent the release of 71,000 tons of greenhouse gas emissions into the atmosphere. That is the equivalent of conserving 12 million therms of natural gas per year, and reduces emissions equivalent to taking 11,800 cars off the road.

In 2009, Republic brought 10 new landfill gas-to-energy projects online. The Company has developed LFGTE projects at more than one-third of its 213 landfills. These 74 projects include:

• 52 electric generating plants
• 13 Medium Btu plants that provide LFG to industrial users
• 6 High Btu plants that produce pipeline quality gas
• 3 leachate evaporators

Also, the Company combined a first-of-its-kind solar technology with an existing biogas-to-energy system to turn its Tessman Road Landfill in San Antonio, Texas into a sustainable energy park.

The 52 electric projects generate 323 MW of electricity, enough to power about 192,000 homes.  The 22 other projects provide or process more than 58,000 scfm of gas, energy needed to heat almost 200,000 homes. The environmental benefits of all of the projects combined are equivalent to removing nearly 4 million cars from the road.
