COVANTA COMPLETES FIRST STAGE IN THE ACQUISITION OF VEOLIA’S
NORTH AMERICAN ENERGY FROM WASTE BUSINESS

FAIRFIELD, NJ, August 24, 2009—Covanta Holding Corporation (NYSE:CVA) (“Covanta” or the “Company”), a world leader in the development, ownership and operation of Energy-from-Waste (EfW) facilities and other renewable energy projects, today announced that it has successfully completed the first stage in the previously announced acquisition of Veolia’s North American EfW business.

The businesses being acquired in this stage of the acquisition consist of six EfW businesses and one transfer station business as follows:

	Facility:	Location:	Capacity:
1.	Long Beach EfW	CA	1,380	TPD
2.	Dutchess EfW	NY	450	TPD
3.	Islip EfW	NY	486	TPD
4.	Montgomery EfW	PA	1,200	TPD
5.	York EfW	PA	1,344	TPD
6.	Vancouver EfW	Canada	800	TPD
7.	Abington Trans. St.	PA	940	TPD

Each of the businesses acquired includes a long-term operating contract with the respective municipal client. The Company also acquired a majority ownership stake in the Montgomery facility. The acquired businesses compliment Covanta’s portfolio, which now includes operation of 44 EfW facilities that process approximately 19 million tons of municipal solid waste annually.

We expect to complete this transaction in its entirety by year’s end with the purchase of the operating contract relating to a 3,000 TPD EfW facility in Miami-Dade, Florida.

“The strategic acquisition of Veolia’s North American EfW business compliments our industry leading portfolio. I am proud of our team for moving so quickly to complete this first stage of the acquisition. We’re excited to be welcoming six new clients and a group of talented employees to the Covanta family and will begin integration efforts immediately that will allow us to achieve operational efficiencies,” said Anthony Orlando, President and CEO of Covanta.
