Dear Mr. Vranka:

We received your letter regarding adoption of final modifications to the State of Colorado’s

Rules and Regulations Pertaining to Radiation Control Parts 1, 8, 9, 16, 19, and 20 sent to us

on January 17, 2007. It is our understanding that the adopted regulations address revisions to

the definitions of byproduct material to implement changes as a result of the Energy Policy Act

of 2005. We discussed this with Ken Weaver on January 30, 2007. 

As stated in our November 30, 2006 letter to you, we will not be performing a review of the

adopted regulations stated above. As you are aware, we are in the process of finalizing our

rules pertaining to the regulations you have submitted for review. Once our rules are finalized a

notice will be published in the Federal Register and an All Agreement State letter will be issued

regarding requirements for compatibility. Please resubmit your regulations at that time with the

appropriate cross walk pursuant to the Office of Federal and State Materials and Environmental

Management Programs (formerly STP) Procedure SA-201, Review of State Regulatory

Requirements. 

We would like to thank you for continually updating us on the status of the State of Colorado’s

regulations. 

If you should have any questions please feel free to contact me at (301) 415-2320 (email:

kxs@nrc.gov) or Monica Orendi at (301) 415-3938 (email: mlo1@nrc.gov.) 

Sincerely,
