Stephen F. Tarlton, Manager 

Radiation Control Program 

Hazardous Materials and Waste Management Division 

4300 Cherry Creek Drive 

South Denver, CO 80246 

Dear Mr. Tarlton: 

We have reviewed the modifications to Colorado’s “Colorado Radiation Control Act” received by 

our office on April 17, 2014, and May 12, 2014. The legislation was reviewed by comparison to 

10 CFR 40, “Domestic Licensing of Source Material”; 10 CFR Part 61, “Licensing Requirements 

for Land Disposal of Radioactive Waste”; and the Suggested State Legislation (SSL) on 

“Radiation Control,” published 1983 by the Council of State Governments. 

Please note that we have limited our review to program elements required for compatibility 

and/or health and safety and the identification of program elements that create conflicts, 

duplications or gaps in the orderly pattern of regulations on a nationwide basis (See the 1997 

Policy Statement on Adequacy and Compatibility of Agreement State Programs). We note that 

Colorado became an Agreement State on January 1, 1968 and amended their Agreement to 

include Section 11e.(2) material of the Atomic Energy Act on April 20, 1982. During the 

negotiations for both the Agreement and the amendment to the Agreement, NRC reviewed 

Colorado’s enabling legislation. 

Based on our review, we have one comment/concern about the legislation in addition to the 

previous comments provided in our October 24, 2011, and on January 16, 2014, letters. We 

discussed our review of the legislation with James Jarvis on May 28, 2014. 

We offer the following comment: 

In Section 1 under 25-11-107 it states, “Under no circumstances shall remediation be 

deemed complete until all groundwater wells affected by any release associated with the 

site or facility are restored to at least the numeric groundwater standards as established 

by the Water Quality Control Commission that apply to the historic uses of the wells. 

The licensee shall remediate any release affecting groundwater wells in the most 

expedited manner reasonably possible using best available active treatment and 

groundwater monitoring technologies.” 
S. Tarlton -2- 

It is unclear what is meant by phrase “numeric groundwater standards as established by 

the Water Quality Control Commission that apply to the historic uses of the wells.” This 

phrase needs to be properly defined or removed from the legislation. In adopting this 

legislation and any implementing regulations, the State needs to consider the 

requirements of its 274b. Agreement with the Nuclear Regulatory Commission. The 

274b. Agreement with Colorado requires the State to comply with Section 274o. In 

Section 274o., it states that a State shall require compliance with standards which shall 

be adopted by the State for the protection of the public health, safety, and the 

environment from hazards associated with such material which are equivalent, to the 

extent practicable, or more stringent than, standards adopted and enforced by the 

Commission for the same purpose. 

In accordance with 274o, the State may adopt alternatives to the requirements adopted 

and enforced by the Commission for the same purpose if, after notice and opportunity for 

public hearing, the Commission determines that such alternatives will achieve a level of 

stabilization and containment of the sites concerned, and a level of protection for public 

health, safety, and the environment from radiological and nonradiological hazards 

associated with such sites, which is equivalent to, to the extent practicable, or more 

stringent than the level which would be achieved by standards and requirements 

adopted and enforced by the Commission. In adopting any alternative standard, the 

State must submit and get approval from the NRC and the alternative standard may not 

preclude a practice (uranium milling). 

We recommend that you address the comment above concerning the authority provided to 

the Department under the 274b. agreement with NRC in addition to the comments outlined in 

the October 24, 2011(Agencywide Documents and Access Management System (ADAMS) 

Number ML112630471), and January 14, 2014(ADAMS Number ML13353A092), letters. 

The State Regulation Status (SRS) Data Sheet summarizes our knowledge of the status of 

other Colorado regulations and legislation, as indicated. Please let us know if you note any 

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