OAK RIDGE, Tenn. – This month, the Oak Ridge Environmental Management (EM) program finished the final phase of the Building K-33 demolition project.

Workers with LATA-Sharp Remediation Services, the prime contractor for the project, recently removed areas of contaminated soil, backfilled the area with topsoil and seeded the land with grass. In April, they removed a 32-acre concrete slab that served as the foundation for the former 1.4 million-square-foot former gaseous diffusion plant in the East Tennessee Technology Park (ETTP). Constructed in 1954, the K-33 facility enriched uranium until 1985.

The superstructure’s demolition is the latest effort to convert ETTP into a private industrial park. To date, Oak Ridge’s EM program has eliminated significant legacy wastes and almost 250 hazardous or unneeded facilities at ETTP.

“The completion of this project brings us considerably closer to our goal of transitioning the East Tennessee Technology Park into a private industrial park,” EM Acting Assistant Manager Sue Cange said.

A majority of the building’s decontamination and decommissioning was performed in 1997, but the latest project removed siding, demolished the building, removed the slab and packaged and transported all associated debris to Oak Ridge’s Environmental Management Waste Management Facility (EMWMF).

K-33’s demolition finished five months ahead of schedule in April 2011, and debris removal was completed in September, three months ahead of schedule. During the nine-month project, 164,000 tons of steel and concrete were transported in 13,000 shipments to the EMWMF for disposal. The slab removal resulted in more than 3,600 shipments of concrete totaling 61,300 tons and 125 cubic yards of disposed contaminated soil.

The K-33 demolition project was funded by a portion of the $755 million Oak Ridge’s EM division received from the American Recovery and Reinvestment Act.
