Radiation Protection Manager

 and Environment 

4300 Cherry Creek Drive S. 

Denver, CO 80246-1530 

Dear Ms. Opila: 

We have reviewed the final revisions to the Colorado regulations Part 4 titled, Standards for 

Protection Against Radiation, received by our office on September 16, 2015. These regulations 

were reviewed by comparison to the equivalent U.S. Nuclear Regulatory Commission (NRC) 

rules and the requirements of the provision identified in the enclosed State Regulation Status 

(SRS) Data Sheet. We discussed our review of the regulations with James Jarvis on 

November 18, 2015. 

As a result of our review, we have two comments that have been identified in the enclosure. 

Please note that we have limited our review to regulations required for compatibility and/or 

health and safety. We have determined that if these regulations are revised, incorporating our 

comments and without other significant change, they would meet the compatibility and health 

and safety categories established in the Office of Nuclear Material Safety and Safeguards 

(NMSS) Procedure SA-200, “Compatibility Categories and Health and Safety Identification for 

NRC Regulations and Other Program Elements.” 

We request that when you revise your regulations to address our comments, a copy of the “as 

published” regulations be provided to us for review. As requested in NMSS Procedure SA-201, 

“Review of State Regulatory Requirements,” please highlight the location of any changes made 

by Colorado, in response to our comments, and provide a copy to the Division of Material 

Safety, State, Tribal, and Rulemaking Programs, NMSS. The SRS Data Sheet summarizes our 

knowledge of the status of other Colorado regulations, as indicated. Please let us know if you 

note any inaccuracies, or have any comments on the information contained in the SRS Data 

Sheet. This letter, including the SRS Data Sheet, is posted on the NMSS State Communication 

Portal: https://scp.nrc.gov/rulemaking.html. 
J. Opila -2- 

If you have any questions regarding the comments, the compatibility and health and safety 

categories, or any of the NRC regulations used in the review, please contact
