The biggest change for a water discharge permit drafted for the Y-12 National Security Complex is the construction and operation of a Mercury Treatment Facility, a state official said Tuesday.

The mercury treatment facility, which is under construction and could begin operating next year, is expected to capture and treat most of the mercury released as old, unused mercury-contaminated buildings, equipment, and soils are demolished and removed, especially on the west side of the nuclear weapons production site.

Millions of pounds of mercury were used at Y-12 in the 1950s and early 1960s to produce nuclear weapons parts. Roughly 60,000 pounds is estimated to remain in buildings and equipment, and an unknown amount was released into soils and sediments. About 1.3 million pounds is unaccounted for. Mercury is a top pollutant of concern on the federal Oak Ridge Reservation.

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

Image from “Final Long-Term Management and Storage of Elemental Mercury Supplemental Environmental Impact Statement” published by U.S. Department of Energy in September 2013.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

The U.S. Department of Energy announced Tuesday that it has completed the site preparations for the construction of the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow DOE to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for use in nuclear weapons during the Cold War (in the 1950s and 1960s). It’s part of a large-scale cleanup and demolition project at Y-12 and an effort to reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced on Tuesday, December 4, that it had awarded a $91 million contract to build the Mercury Treatment Facility at Y-12. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

DOE said early site preparation activities were started by other contractors in December 2017. A groundbreaking was held at the site in November 2017, and UCOR, DOE’s lead cleanup contractor in Oak Ridge, began work at the treatment facility site with a subcontractor after the groundbreaking, the DOE Oak Ridge Office of Environmental Management said in a story published Tuesday in an EM Update.

The Mercury Treatment Facility will have two components: a headworks facility and a treatment plant connected by a pipeline. The headworks facility will capture creek flow on the west end of Y-12, store excess stormwater collected during large rainfalls, remove grit, and pump water through the pipeline to the treatment plant on the east side of Y-12. The treated water will then flow into East Fork Poplar Creek. [Read more…]

The federal spending bill approved last week includes $639 million for the federal government’s cleanup program in Oak Ridge, including what could be full funding for a top priority deactivation and demolition project at the Y-12 National Security Complex.

The $639 million for the current fiscal year is an increase of $141 million or more, compared to recent fiscal years, and it’s the most money appropriated in a while.

Besides Y-12, the fiscal year 2018 funding will be used for U.S. Department of Energy cleanup projects at East Tennessee Technology Park (the former K-25 site) and Oak Ridge National Laboratory.

“It’s very positive for us,” said Jay Mullis, manager of the DOE Oak Ridge Office of Environmental Management, or OREM. Mullis gave a brief update at a meeting of the Oak Ridge Reservation Communities Alliance on Monday.

In addition to $125 million to deactivate and demolish the Biology Complex at Y-12, the fiscal year 2018 spending bill includes $17.1 million in funding for the planned Mercury Treatment Facility at Y-12, about $200 million for continued cleanup work at ETTP, and a total of roughly $12 million for the Environmental Management Disposal Facility, or EMDF. That’s a proposed landfill that could be west of Y-12 and accept waste from future cleanup work at Y-12 and ORNL, possibly early in the 2020s. The project plan for EMDF is expected to be open to public comment later this summer. [Read more…]

Note: This story was published in the November 21 edition of “EM Update” by the U.S. Department of Energy Office of Environmental Management. EM Update recently spoke with Jay Mullis, the new manager of the Oak Ridge Office of Environmental Management (OREM), about his vision and priorities for the EM program in Oak Ridge.

What are your main priorities going forward as the new manager of OREM?

Overall, I want to ensure our program maintains the momentum we’ve achieved during the past several years. First, it is important for us to continue pushing forward to complete cleanup at the East Tennessee Technology Park (ETTP, also known as the former K-25 site) by 2020. This will facilitate the transfer of the site back to the community so it can be transformed into a vibrant industrial park capable of generating jobs and economic growth for the region. It will also allow our program to shift its focus and resources toward cleanup at two important, active DOE sites: the Y-12 National Security Complex and Oak Ridge National Laboratory (ORNL). Before we finish our cleanup mission at ETTP, we must also fulfill our historic preservation commitments to preserve and celebrate the many achievements that occurred there during the Manhattan Project and Cold War. 

Secondly, it is very important that we begin laying the foundation for our next big challenges at Y-12 and ORNL. That began on November 20, when we broke ground on the new Mercury Treatment Facility at Y-12. This critical piece of infrastructure will provide an important control measure for mercury and opens the door for us to clean and remove mercury contaminated facilities and soils. Additionally, it is crucial to construct another onsite disposal facility that will provide the space necessary for the waste generated by completing cleanup at Y-12 and ORNL. 

Finally, we will continue our focus on eliminating Oak Ridge’s waste inventory. We are making progress packaging and disposing transuranic waste from ORNL with the Waste Isolation Pilot Plant again accepting shipments. We are working to eliminate the remaining portion of the uranium-233 inventory from ORNL to improve safety and significantly reduce security costs.

The new Mercury Treatment Facility at the Y-12 National Security Complex will help reduce the amount of mercury that gets into East Fork Poplar Creek and allow the demolition of four large buildings where mercury was used to help make nuclear weapons during the Cold War, officials said Monday.

Mercury contamination is one of the biggest problems remaining from the Cold War, U.S. Senator Lamar Alexander said during a groundbreaking ceremony on Monday morning. Alexander, a Tennessee Republican, first announced the new treatment facility at Y-12 more than four years ago.

“In May 2013, I came to Oak Ridge to announce that a new water treatment facility would be built at Y-12 at the head of the East Fork Poplar Creek to prevent mercury that was once used to make nuclear weapons from getting into our waterways,” Alexander said. “That day, I made a personal commitment to address one of the biggest problems we have from the Cold War era—mercury contamination—and help fund a solution. Today, I am proud to see that we are breaking ground on the new water treatment facility.”

Site preparation for the new Mercury Treatment Facility is expected to start this year, with the rest of construction beginning in late 2018. The facility is expected to start operating in late 2022.

The treatment plant will allow workers to demolish four large buildings where mercury, a toxic metal, was once used: Alpha 2, Alpha 4, Alpha 5, and Beta 4. Work on those buildings, mostly on the west side of Y-12, could start by 2024. [Read more…]

A groundbreaking has been scheduled for Monday morning for the Mercury Treatment Facility at the Y-12 National Security Complex.

Y-12 operations have historically used large amounts of mercury, and many of the buildings, now in varying states of deterioration, have mercury contamination, a media advisory said.

“The treatment facility will lower existing mercury levels from past releases and will serve as a guard against a potential increase in releases as mercury-contaminated buildings are demolished,” the media advisory said.

Deputy Energy Secretary Dan Brouillette will attend the groundbreaking, which is at Y-12 and not open to the public. U.S. Senator Lamar Alexander and U.S. Representative Chuck Fleischmann, both Tennessee Republicans, will also attend the groundbreaking, the media advisory said.

The groundbreaking is being presented by the U.S. Department of Energy and URS|CH2M Oak Ridge LLC, or UCOR, DOE’s cleanup contractor at federal sites in Oak Ridge. [Read more…]

Cleanup funding could be up for the U.S. Department of Energy under the budget request from the Trump administration for fiscal year 2018, and there could be benefits for Oak Ridge, according to budget documents.

President Donald Trump submitted his budget request to Congress on Tuesday, May 23. In that request, the DOE Office of Environmental Management, or EM, asked for $6.5 billion, the largest request in a decade. That would be $290 million above fiscal year 2016.

The funding request for Oak Ridge includes $390 million, or $78 million below fiscal year 2016, to continue deactivation and demolition of remaining facilities at East Tennessee Technology Park, continue preparing Building 2026 to support the processing of the remaining U-233 material at Oak Ridge National Laboratory, and to support activities for the Mercury Treatment Facility at Y-12 National Security Complex.

It’s not clear whether that $390 million in the funding request includes part of the $225 million in funding requested for high-risk excess contaminated facilities at Y-12 and Lawrence Livermore National Laboratory in California. It’s also not clear whether the total funding for Oak Ridge cleanup programs would be up or down, compared to previous years. The DOE public affairs office in Washington, D.C., has not responded to about a dozen budget-related inquiries from Oak Ridge Today since May 23.

Among the highlights of the EM request for Oak Ridge, according to budget documents posted online by DOE and an EM press release: [Read more…]
