Introduction
The East Tennessee Waste Treatment Center (ETWTC) is located in a complex of existing contaminated buildings on the East Tennessee Technology Park (ETTP), formerly known as the K-25 Site, near Oak Ridge, Tennessee. The buildings are leased by the Community Reuse Organization of East Tennessee (CROET) to the East Tennessee Materials and Energy Corporation (M&EC). The ETWTC operates as a commercial facility, regulated by the Tennessee Department of Environment and Conservation (TDEC).
Facility Capability
The buildings that comprise the ETWTC include K-1200 (Center and South Bays), K-1052, K-1052B, K-1005, K-1010, and K-1023. The ETWTC is a fully integrated mixed waste treatment system consisting of six major process units. The facility provides effective treatment pathways capable of handling and treating a wide range of raw waste chemical and physical characteristics.
A full spectrum of physical waste forms can be prepared and treated. The chemical compositions of treatable waste include the characteristics of ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity due to contamination with all of the RCRA-regulated toxic metals and organic compounds (EPA Waste Codes D004 through D043), and TSCA-regulated PCBs. An extensive spectrum of EPA-listed waste codes in the F, P, and U lists can also be accommodated.
Radiological content is limited to low-level wastes. For atomic numbers 1-92, a total site inventory not to exceed 100 ci is anticipated. For atomic numbers 93-101, a total site inventory not to exceed 1 ci, and material contamination limits not to exceed 100 nCi/g of material is anticipated. The facility may not accept fissile materials in an amount that would total a fissile quantity on a total inventory basis.
The facility has a RCRA permit and radioactive material license. Air pollution control permits have also been received. The facility will have no aqueous discharges to surface waters; therefore, no wastewater discharge permits will be required.
The facility has completed all First Article Tests for Category A waste and is receiving and processing production quantity waste. M&EC is expected to complete the First Article Test for Category B (RCRA/PCB) in FY 2003.

ETWTC Treatment Systems
- Direct chemical oxidation - Direct chemical oxidation (DCO) treats waste contaminated with TSCA-regulated PCBs or RCRA-regulated organic compounds. The unit uses a combination of low-temperature thermal desorption and chemical oxidation to destroy the regulated organic compounds to concentrations less than the LDR or TSCA limits.
- Stabilization - Prepared wastes or size-reduced debris contaminated with RCRA-regulated metals will be treated in the Stabilization Unit to first chemically precipitate the metals into a low-solubility form, and then stabilize the waste matrix using appropriate binders. Reliance upon precipitation chemistry rather than the binder to stabilize the metals allows the weight and volume of binder to be minimized, thus minimizing final waste disposal volume. Debris rule treatment by microencapsulation may also be performed in this system.
- Aqueous waste treatment - The Aqueous Waste Unit has the capability to receive aqueous liquids in drums or in bulk from an outside generator, or internally generated decontamination waters and process condenses. These liquid wastes will be treated by equalization, neutralization, precipitation, filtration, ion exchange, and activated carbon adsorption as appropriate. Sludges from the DCO system, the reactive waste system, and the aqueous waste system, as well as various customers can be dewatered and dried in a sludge handling system.
- Reactive waste treatment - The Reactive Waste Unit is similar in concept to the Aqueous Waste Unit, except that it is specifically designed to treat high-concentration cyanide, sulfide and strong oxidizer waste liquids.
- Mercury amalgamation - In this system, waste materials having mercury concentrations over 260 mg/kg are treated by amalgamation. This unit can perform amalgamation of liquid elemental mercury.
