Reindustrialization efforts at the East Tennessee Technology Park have brought new life to an old barge access area out of service for decades.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management is cleaning and converting the former uranium enrichment complex into a private sector industrial park, and companies are seeing significant signs of progress and potential.

In September, UniTech Services Group, a private business at ETTP, the former K-25 site, needed to transport large industrial equipment from Michigan and noted the site’s neglected barge area. The company worked with DOE and the Community Reuse Organization of East Tennessee to use this area, and successfully shipped the equipment to ETTP using the Mississippi, Ohio, and Tennessee navigable river systems.

The radioactive nuclide that was first detected in the city’s wastewater lines more than two years ago near the demolition project at the former K-25 Building doesn’t affect drinking water, and it’s not believed to pose any threat to residents or municipal employees, officials said this month.

The levels of the radionuclide, technetium 99, are dropping at several measuring spots in the sewer system in west Oak Ridge, but it’s not clear how long UCOR, the federal government’s cleanup contractor, might have to ship sludge from the Rarity Ridge Wastewater Treatment Plant to an out-of-state landfill.

Officials said UCOR has already hauled away about 80,000 gallons of sludge using a 5,000-gallon tanker truck about once every one or two months since 2014. The sludge, which is about 3 percent to 4 percent solid, comes from a part of the plant known as a digester, and the shipments vary depending upon how much is processed at the plant each month.

Officials don’t know yet when the shipments might end. The sludge is now being taken to the Perma-Fix Northwest treatment facility in Richland, Washington. The last shipment was this month. [Read more…]
