Crews are expected to finish remediating soil, reversing or stopping environmental damage at the former K-25 site in west Oak Ridge this year, and federal cleanup managers are shifting their focus to groundwater. It’s the final phase of cleanup at the former uranium enrichment site.
Now also referred to as Heritage Center and East Tennessee Technology Park (ETTP), the K-25 site produced fuel for nuclear weapons and reactors starting in the top-secret Manhattan Project during World War II and continuing through the Cold War. The site has been shut down for almost four decades, and a massive cleanup project has been under way for many years.
The groundwater work can begin with the recent signing of two records of decision between the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, U.S. Environmental Protection Agency, and Tennessee Department of Environment and Conservation. That’s according to “EM Update,” an electronic newsletter published by DOE’s Office of Environmental Management.
There will be an open house in Oak Ridge on Thursday to discuss the proposed new federal landfill in Bear Creek Valley, west of the Y-12 National Security Complex.
The open house is scheduled from 5 to 7 p.m. Thursday, December 8, in the Scarboro Community Center.
“After much work and coordination with the U.S. Environmental Protection Agency and Tennessee Department of Environment and Conservation, we are excited to share that the three parties recently signed the final Record of Decision (ROD) for the Environmental Management Disposal Facility (EMDF) project,” the U.S. Department of Energy’s Oak Ridge Office of Environmental Management said in a notice posted on its website.

More than 4,000 fish and crayfish were killed by chlorinated water and mercury at the Y-12 National Security Complex in two series of incidents in 2018 and 2021.
The first series of incidents was likely caused by the release of mercury while crews were cleaning up and removing equipment at the Alpha-4 Building on the west side of Y-12, according to scientists and officials. Alpha-4 is the most contaminated of the four major mercury-contaminated buildings at Y-12. Millions of pounds of mercury were used at Y-12 decades ago to produce nuclear weapons parts. Removing mercury-contaminated buildings, equipment, and soil remains one of the top challenges of cleaning up the Oak Ridge Reservation.

Note: This story was last updated at 3:20 p.m. June 6.
Millions of gallons in sewer system overflows were reported to the state by the City of Oak Ridge between 2012 and 2017, and most of the largest overflows—500,000 gallons or more—were reported in the summer of 2013, according to a federal lawsuit that could be settled soon.
The lawsuit by Tennessee Riverkeeper, a nonprofit organization based in Alabama, was filed in U.S. District Court in Knoxville in 2018. It alleged that the city had reported about 40 million gallons of sewer system overflows in a four-year period near local waters and that the city had violated the Clean Water Act. The city denied the claim. The lawsuit had sought to force the city to make repairs to keep pollutants out of creeks and rivers, and to charge the city $37,500 per violation per day. It also asked the city to pay reasonable attorney’s fees and expert fees. Riverkeeper said the discharges have affected how often its members use the Tennessee River and its tributaries for recreation. The discharges continued through at least early 2017, with more overflows reported later, according to the lawsuit and legal documents filed in the case.
Now, the lawsuit could be settled if the court approves and Oak Ridge makes at least $4 million in repairs by 2025 and pays more than $100,000 in attorneys’ fees. The settlement agreement was approved by City Council in May. A notice about the agreement was filed in U.S. District Court in Knoxville on Thursday.
The largest overflows, by volume, were reported about two years before the city completed millions of dollars worth of repairs to its aging sewer system and built three large wastewater holding tanks after an order from the U.S. Environmental Protection Agency in 2010. The EPA order had required the city to bring itself into compliance with its discharge permit. However, the overflows continued even after the city said it had satisfied the conditions of the EPA order, according to the lawsuit, although the overflows appeared to be at a lower volume than in the summer of 2013.
Legal arguments in the case have included debate over whether Tennessee Riverkeeper has standing—someone who had been injured by the sewer system overflows—and whether the discharges have continued.

The City of Oak Ridge closed on a $20.7 million federal loan on Thursday for a new water treatment plant in south Oak Ridge.
It’s a Water Infrastructure Finance and Innovation Act, or WIFIA, loan. The funds provided by the federal loan program will be used to design and build the new water plant, which will replace an aging facility on Pine Ridge that has served the community since the 1940s.
The total cost for replacement of the water treatment plant is estimated to be $42.2 million, the city said in a press release on Friday. WIFIA will provide about 49 percent of that cost, with the city using the Tennessee State Revolving Fund Loan Program to cover the balance, the press release said.
“After three years of application and planning, the City of Oak Ridge has reached a significant milestone in the funding needed for a new replacement water plant,†Oak Ridge City Manager Mark Watson said in the press release. “WIFIA has helped Oak Ridge with a low-interest federal loan, allowing us to avoid potential failures in a system originally designed for a different Oak Ridge. The financial terms will allow Oak Ridge to afford these much-needed improvements to serve not only our residents, but the national security and U.S. Department of Energy facilities located here.â€
Low-interest loan will go toward new water treatment plant
Tennessee Governor Bill Lee and Tennessee Department of Environment and Conservation Commissioner David Salyers on Monday announced approximately $3.2 million in a low-interest loan for drinking water infrastructure improvements for the City of Oak Ridge.
“This loan will help Oak Ridge to meet one of the vital needs of its citizens,†Lee said in a press release. “I am pleased to support infrastructure upgrades that will help to provide safe and reliable drinking water for more Tennesseans.â€
The City of Oak Ridge will receive a planning and design loan in the amount of $3,288,000 to develop plans and specifications for construction of a new 16-million-gallon-per-day water treatment plant, the press release said. The effort is funded from the State Revolving Fund Loan Program with a five-year repayment period and an interest rate of 1.08 percent.
The partial shutdown of the federal government is not affecting the U.S. Department of Energy’s cleanup program in Oak Ridge, a spokesperson said Friday.
The U.S. Environmental Protection Agency provides federal oversight of the work, and EPA is one of the federal departments and agencies affected by the partial government shutdown.
But on Friday, Ben Williams, spokesperson for the DOE Oak Ridge Office of Environmental Management, said the shutdown is not affecting the office’s cleanup work at this time. [Read more…]
Pictured above in a file photo from February 2014 is the headquarters of Information International Associates on Union Valley Road in Oak Ridge.
About a dozen employees of Information International Associates Inc. have been affected by the partial shutdown of the federal government, an executive said in response to questions on Wednesday.
IIA staff members who support the U.S. Environmental Protection Agency in Washington, D.C., and Cincinnati, Ohio, have been affected by the shutdown, said Kelly Callison, senior vice president of operations.
“All the rest of the agencies we support have funding,” Callison said.
He said about 12 IIA staff members are affected to some extent. Two of those employees are part-time, and three have shifted work to another project but that will end soon. [Read more…]
The partial shutdown of the federal government does not affect state oversight of the federal cleanup program in Oak Ridge, a state official said Thursday.
At this time, the federal shutdown has no impact on the Tennessee Department of Environment and Conservation, said Kim Schofinski, TDEC deputy communications director. That means state oversight of the Oak Ridge cleanup program is not currently affected. The Oak Ridge sites include East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. [Read more…]
You can comment on the proposed new federal landfill in Bear Creek Valley during a public information session in Oak Ridge today (Thursday, September 13).
The landfill would be called the Environmental Management Disposal Facility, and it would be 2.2 million cubic yards on land owned by the federal government. It would be used by the U.S. Department of Energy to dispose of waste from the Oak Ridge Reservation.
The public information session is scheduled from 4:30-6 p.m. Thursday at the DOE Information Center in east Oak Ridge at 1 Science.gov Way. The meeting is hosted by DOE, the U.S. Environmental Protection Agency, and the Tennessee Department of Environment and Conservation.
The purpose of the meeting is to share information about the proposed plan and hear public comments, according to a public notice sent to Oak Ridge Today on Wednesday afternoon. [Read more…]

The U.S. Environmental Protection Agency has invited the City of Oak Ridge to apply for a new federal loan program for the city’s proposed new water plant, a press release said.
The City of Oak Ridge water plant is one of 12 projects in nine states to apply for more than $2 billion in Water Infrastructure Finance and Innovation Act (WIFIA) Loans, the EPA said in a press release Wednesday. The projects were selected from a group of 43 projects that submitted letters of interest to EPA in April 2017.
“Rebuilding America’s infrastructure is a critical pillar of the president’s agenda,†said EPA Administrator Scott Pruitt. “These large-scale projects will improve water quality for 20 million Americans, especially those communities that need it the most—such as rural and urban communities.â€
The press release said the City of Oak Ridge will design and construct a new 16 million-gallons-per-day membrane treatment plant and associated equipment to replace the existing decades-old conventional treatment plant, which is currently at capacity and beyond its useful life.
Among the city’s water plant customers are Oak Ridge National Laboratory and Y-12 National Security Complex.
“This project will provide sufficient capacity to meet the city’s water needs by continuing the production and delivery of safe potable drinking water to its customers,” the EPA press release said. [Read more…]
