AECOM (NYSE:ACM), a premier, fully integrated global infrastructure firm, announced today that the U.S. Department of Energy's (DOE's) Office of River Protection in Richland, Wash., intends to extend the current tank operations contract with AECOM-led Washington River Protection Solutions LLC. The approximate US$725 million extension will run up to 12 months, from October 1, 2019, to September 30, 2020. The estimated value of the contract extension will be added in AECOM's backlog in the fourth quarter of fiscal 2019.

During the contract extension period, the AECOM-led joint venture will safely and efficiently manage retrieval and treatment of radioactive tank waste to protect the Hanford Site. AECOM has a long history of supporting the DOE at the Hanford Site and extensive experience in liquid waste disposition. "We look forward to continuing our support of the DOE, partnering with them to make progress in this vital cleanup mission and reducing the state of Washington's environmental risk," said Mark Whitney, executive vice president and general manager of AECOM's Nuclear and Environment strategic business unit.
