## Mr. Casey Gadbury, Manager National TRU Program Carlsbad Field Office U.S. Department of Energy P.O. Box 3090 Carisbad, NM 88221-3090 Dear Mr. Gadbury:
This letter provides the results of the U.S. Environmental Protection Agency's (EPA) continued eompliance inspection (Inspection No. EPA-INL-CCP 09.08-24) of theCentral Characterization Project (CCP) waste characterization (WC) program for contacthandled (CH) transuranic (TRU) waste at the Idaho National Laboratory (INL) in Idaho Falls, Idaho. As a result of this continued compliance inspeetion, EPA confirmed that the INL-CCP CH TRU WC program characterizes CH TRU waste consistent with the conditions and limitations from EPA's baseline approval granted in November 2005. The enclosed report (EPA Air poeket No. A-98-49; I1-A4-112) gives the details of the evaluation. In accordance with 40 CFR 194.8(b), this on-site inspection occurred at the Radioactive Waste Management Complex (RWMC) loeated at INL on September 16-18, 2008. The onsite inspection covered all TRU waste charaeterization proeesses except acceptable knowledge (AK). EPA inspected AK separately by desktop review between October and December 2008. EPA gave the baseline approval to the INL CCP's CH TRU waste eharaeterization program in November 2005, in accordance with 40 CFR 194.8(b). During this inspection, the Agency evaluated a sample of the following WC activities: • Acceptable knowledge (AK) • Two nondestructive assay (NDA) systems, the Waste Assay Gamma Spectrometer (WAGS) and the Super High Efficiency Neutron Counter (SuperHENC) for eharacterizing CH TRU wastes • Real-time radiography (RTR) for CH retrievably-stored TRU debris waste • Visual Examination Technique (VET) for newly-generated TRU waste • Container Management

## EPA eontinues the approval of the INL-CCP CH TRU WC program in the

eonfiguration observed during this inspection eonsistent with the limitations described in the baseline inspection report (see EPA Docket No.A-98-49; II-A4-59). Since the baseline approval, EPA added new Tier I and Tier 2 items to the original baseline approval. The attached table below summarizes the EPA's current approvai status of INL CCP's CH TRU waste characterization activities. If you have any questions, please contact Rajani Joglekar (202 343-9462) or Ed Feltcorn (202 343- 9422.
