The U.S. Department of Energy has awarded a $91 million contract to build the Mercury Treatment Facility at the Y-12 National Security Complex.

It’s part of an effort to reduce the amount of mercury in East Fork Poplar Creek and allow the demolition of several large Y-12 buildings where mercury was used to help make nuclear weapons during the Cold War.

The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC, DOE said Tuesday. [Read more…]

U.S. Department of Energy officials have released a new plan to address mercury contamination at the Oak Ridge Reservation in Tennessee and Savannah River Site in South Carolina. It advocates for research and the development of technologies that could resolve key technical uncertainties with mercury in environmental remediation, the deactivation and decommissioning of facilities, and processing waste in tanks.

The Oak Ridge Reservation and Savannah River Site both used mercury in industrial-scale processes. At the Oak Ridge Reservation, large quantities of mercury were used at the Y-12 National Security Complex from the early 1950s until the early 1960s. During the peak period of operations, according to estimates from the Oak Ridge Office of Environmental Management, or OREM, 700,000 pounds of a total 20 million pounds of mercury that were used were released into the surrounding environment.

Ongoing mercury abatement and remediation efforts at Y-12 that began in the 1980s have decreased overall mercury releases to the environment, the DOE Office of Environmental Management, or EM, said in a May 31 newsletter.

But elevated concentrations remain in certain water, soil, and facilities, federal officials said. [Read more…]

Construction on Y-12 mercury treatment plant could start in 2018, cost $146 million

Construction on a mercury treatment plant at the Y-12 National Security Complex could start in 2018 and cost $146 million, a federal official said Wednesday.

The plant would treat mercury contamination that originates in the West End Mercury Area at Y-12, flows through storm drains, and enters Upper East Fork Poplar Creek at a point known as Outfall 200. East Fork Poplar Creek flows through Oak Ridge.

The U.S. Department of Energy has evaluated several alternatives for treating the mercury, including doing nothing. But DOE prefers an option that would treat 3,000 gallons of contaminated water per minute and store two million gallons of stormwater. It could reduce the flow of mercury, a toxic metal, by an estimated 84 percent. [Read more…]
