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.
The Tennessee Department of Environment and Conservation mobile household hazardous waste collection service will be in Roane County on Saturday, March 9.
Tennesseans are encouraged to bring household hazardous waste – including cleaning fluids, pesticides, swimming pool chemicals, and more – to a designated drop-off location, a press release said. A person does not need to live in the county to participate.
The Tennessee Department of Environment and Conservation mobile household hazardous waste collection service will be in Anderson, Cheatham, and Wilson counties on Saturday, October 7.
“Tennesseans are encouraged to bring household hazardous waste—including cleaning fluids, pesticides, swimming pool chemicals, and more—to a designated drop-off location,” a press release said. “A person does not need to live in the county to participate.”
The U.S. Department of Energy has asked for public comment about a proposed plan to reduce groundwater contamination in the main plant area of East Tennessee Technology Park, the former K-25 site in west Oak Ridge.
Comments are for an interim record of decision. There will be a public meeting Tuesday evening in Oak Ridge.
“The proposed plan identifies enhanced in situ bioremediation (EISB) as DOE’s preferred alternative to remediate six specific areas of groundwater in the main plant area of the East Tennessee Technology Park,” DOE said in a public notice distributed by the Tennessee Department of Environment and Conservation. “EISB is a method that involves using microorganisms to reduce contamination levels in these specific areas of groundwater. For these six areas, workers have excavated, or will excavate, the primary sources of contamination, as specified in the Record of Decision for Soil, Buried Waste, and Subsurface Structure Actions in Zone 2, East Tennessee Technology Park, Oak Ridge, Tennessee (DOE/OR/01-2161&D2).
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.
Almost 5,000 pounds of hazardous household waste was collected at a drop-off event in Anderson County this month.
The Household Hazard Waste drop-off on October 1 was sponsored by Anderson County Solid Waste Management Department and the Tennessee Department of Environment and Conservation. They collected 4,798 pounds of household hazardous waste, a press release said.
The TDEC collection report indicated 1,874 pounds of poisonous material (e.g., pesticides) was dropped off that day by area residents at the collection site in Oak Ridge. Other hazardous materials collected included 664 pounds of oil-based paint, 769 pounds of non-hazardous liquid, 616 pounds of flammable liquid, 460 pounds of corrosive material, 289 pounds of aerosol containers, and 61 pounds of fluorescent tubes.

An air quality alert is in effect until midnight as smoke from wildfires in western states and Canada continues to blow through the region. The smoke also affected air quality in the region last week.
On Friday, the Tennessee Department of Environment and Conservation issued a code orange air quality alert for fine particulate matter, including in the Knoxville metropolitan area. The air quality alert includes Anderson County. It went into effect at midnight Friday and continues until midnight Saturday.
The orange alert means the air is unhealthy for people in sensitive groups, according to AirNow.gov. This includes people with heart or lung disease, older adults, children, and teenagers. They should choose less strenuous activities, like walking instead of running, so they don’t breathe as hard. They should also shorten the amount of time they are active outdoors, and postpone outdoor activities if possible to when the air quality is better. Everyone else can enjoy outdoor activities, AirNow.gov said.

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.

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 Tennessee Valley Authority’s Bull Run Fossil Plant is pictured above in Claxton on Monday, Aug. 27, 2018. (Photo by John Huotari/Oak Ridge Today)
The Anderson County Commission has scheduled a public hearing to discuss a request from the Tennessee Valley Authority to build a 60-acre landfill on the Bull Run Fossil Plant site in Claxton.
The hearing is scheduled to start at 4 p.m. Tuesday, February 18, in Room 312 of the Anderson County Courthouse at 100 North Main Street in Clinton.
The proposed new landfill is known Site J, and it has been characterized as a three-cell unit capable of holding eight to nine million cubic yards of coal combustion residuals, according to a public hearing notice.
Tennessee officials on Friday announced a $500,000 loan for water system repairs in Oliver Springs.
The loan was announced by Tennessee Governor Bill Lee and the Tennessee Department of Environment and Conservation Commissioner David Salyers. It’s a Clean Water State Revolving Fund, or SRF, planning and design loan. It’s meant to remediate water losses in the Oliver Springs water system in what is being described as a pilot project.
The loan consists of 100 percent principal forgiveness in the amount of $500,000 with a five-year term and a 0 percent interest rate, a press release said.
“We are pleased we can assist local communities with important infrastructure improvements,†Lee said in the press release. “This loan directly addresses a need and will improve quality of life.â€
