P.O. Box 3090 

Carlsbad, NM 88221 

Dear Dr. Moody: 

The Environmental Protection Agency (EPA) has reviewed the information 

provided by the Department of Energy (DOE), Carlsbad Field Office (CBFO) in your 

January 28, 20091etter reporting the Tier 2 changes to the waste characterization activities 

conducted by the Central Characterization Project (CCP) at Idaho National Laboratory 

(INL), the Savannah River Site (SRS), the Argonne National Laboratory (ANL), the Los 

Alamos National Laboratory (LANL) as well as at the Hanford and Advanced Mixed Waste 

Treatment Project (AMWTP). DOE reported changes implemented to characterize contacthandled (CH) transuranic (TRU) waste for the three-month period beginning October 2008 

through December 2008, as required by EPA's baseline approvals for these sites. EPA does 

not object to any of the changes reported in the enclosures to your letters. 

For some of the documents (See Enclosure) listed in your Tier 2 notification letter 

we would like you to provide the entire documents so that we can better understand the 

specific topic, and so that we stay better informed of the exact nature of the changes at the 

waste generator sites. This information will also assist us in planning future inspections. 

We request that CBFO provide the documents in electronic format, such as via the internet 

or on a compact disc and then notify EPA by e-mail when they are available. 

Please contact Rajani Joglekar (202-343-9462) or Ed Feltcorn (202-343-9422) if you have 

any questions. 

Sincerely, 

/' PZ00~7 ~
