Part 7, 17 and 22 Rulemaking

The department held a request for rulemaking before the Colorado Board of Health on August 17, 2022. The board granted the request and a rulemaking hearing is scheduled for October 19, 2022. Refer to the notice of public rulemaking for additional information on the October hearing. The Board of Health Request for the Part 7, 17, and 22 Rulemaking Package contains the most recent version of the proposed rules.

Proposed changes to Part 7, Part 17 and Part 22 radioactive materials regulations

The proposed rule changes to these radioactive materials-related regulations are needed to conform to recent minor federal rule changes of the U.S. Nuclear Regulatory Commission and to make minor editorial corrections. The purpose and intent of each proposed change is described in the side margin comments of the draft rules as presented to the Board of Health during the August 17 request for rulemaking.

Stakeholders may also refer to the rule change summary for further information about the proposed changes to these regulations. 

Note that the proposed rule changes will not impact facilities that use only x-ray machines.

Stakeholder comment period

We held a stakeholder comment period from May 23 - June 30, 2022. We did not receive any stakeholder comments. 
Due to the minor nature of the rule changes, we did not hold any stakeholder meetings. Stakeholders may, however, contact rulemaking staff at any time with questions about these proposed rule changes.
See the full rulemaking schedule (timeline) for these rules.

Part 20 (TENORM) and Part 12 Rules

Following an extensive stakeholder process, on November 18, 2020, the Colorado Board of Health adopted the Part 20 TENORM rule along with related changes to the Part 12 regulation. The new rule became effective on January 14, 2021 and is enforceable beginning July 14, 2022.
