SN3 TO CONTINUE DISPOSAL OPERATIONS AT HANFORD SITE

NEWPORT NEWS, Va., June 26, 2015 (GLOBE NEWSWIRE) -- Huntington Ingalls Industries (NYSE:HII) announced today that its Stoller Newport News Nuclear (SN3) subsidiary, together with contract partner Wastren Advantage Inc., was awarded a two-year extension to continue disposal operations at the Environmental Restoration Disposal Facility on the U.S. Department of Energy's Hanford Site in Washington.

The total contract, valued at up to $65 million, will expire in September 2017. Washington Closure Hanford (WCH), the awarding agency, operates the Environmental Restoration Disposal Facility for the Department of Energy.

"We are extremely pleased the WCH has chosen to exercise the first option period of our contract," said SN3 President Nick Lombardo. "We believe this reflects the value we have provided to the Hanford Site for safe and compliant operations."

In the 1940s, the Hanford Site was used to produce plutonium for weapons production processes that left solid and liquid wastes, posing a risk to the local environment. In 1989, the Department of Energy, Environmental Protection Agency and Washington State Department of Ecology entered into a legally binding accord, the Tri-Party Agreement, to clean up the Hanford Site.

Formerly known as Stoller, the company has had a presence at the Hanford Site for more than 12 years. SN3 is now a full-service nuclear operations and environmental services company that combines the expertise of HII's S.M. Stoller Corp. and Newport News Nuclear subsidiaries. Based in Broomfield, Colorado, the new company, announced in January, provides the Department of Energy and Department of Defense markets with a one-stop resource for nuclear operations and environmental services capabilities.
