Part 10 Rulemaking

We are holding a stakeholder process to engage and notify stakeholders about minor proposed changes to the Colorado Rules and Regulations Pertaining to Radiation Control, Part 10, titled “Radiation Control – Notices, instructions, and reports to workers: inspections”. The primary purpose of the proposed changes is to clarify language for consistency with other radiation control regulations and formatting and to ensure more consistent language with federal rules in 10 CFR Part 19. This rulemaking does not include any substantial changes to the existing requirements.

To better understand all changes being proposed, interested parties should review all of the documents on this page, including:

Stakeholder comment period

A stakeholder comment period for these regulations begins on March 1, 2024 and ends on March 31, 2024. Stakeholders are invited to provide written comments on the proposed regulations to cdphe_CORadRegs@state.co.us on or before March 31, 2024.

Due to the minor nature of the proposed changes, no stakeholder meetings are scheduled for this rulemaking. Stakeholders are encouraged to submit comments in writing or contact the radiation program staff for additional information. Staff contact information may be found on the Part 10 rulemaking schedule.
 

Part 21 rulemaking: Radon LIRMA program

We are holding a stakeholder process to engage and notify stakeholders about proposed changes to the Colorado Rules and Regulations Pertaining to Radiation Control, Part 21, titled “Colorado Low Income Radon Mitigation Assistance (LIRMA) Program”. The proposed changes will clarify existing language and requirements for consistency with the wording of the Colorado Department of Regulatory Agencies (DORA) licensing requirements for radon measurement and mitigation professionals.  

To better understand all changes being proposed, interested parties should review all of the documents on this page, including:

Stakeholder comment period

A stakeholder comment period will begin on February 5, 2024 and ends on March 6, 2024. Stakeholders are invited to provide written comments to cdphe_CORadRegs@state.co.us on or before March 6, 2024.

Due to the minor nature of the proposed changes, no stakeholder meetings are scheduled for this rulemaking. We encourage stakeholders to submit comments in writing or contact the radiation program staff for additional information on Part 21.

attendance.

Part 4 Rulemaking

In late April 2023 the department began a stakeholder process for Part 4 of the Colorado Rules and Regulations Pertaining to Radiation Control titled “Standards for protection against radiation”. The stakeholder comment period ended on May 29, 2023 and we received no comments. At the rulemaking hearing on October 18, 2023, the Colorado Board of Health adopted the changes as proposed and the Part 4 final rule became effective December 15, 2023.

This rule change revised section 4.18.3 to replace the current language with a recordkeeping requirement related to determining the need for occupational monitoring. The recordkeeping requirement is specific to certain persons required to register under Part 2. In addition, we are proposing minor editorial and formatting corrections and changes for consistency with other current radiation regulations.

To understand the changes being proposed, interested parties are encouraged to review all of the documents on this page, including:

Part 3 Rulemaking for radium-226 antiquities

In April 2023 the department began a stakeholder process for Part 3 of the Colorado Rules and Regulations Pertaining to Radiation Control titled “Licensing of radioactive material. The stakeholder comment period ended on May 15, 2023 and no comments were received. At the request for rulemaking before the Colorado Board of Health on July 19, 2023, the Board scheduled a rulemaking hearing on September 20, 2023. Due to a filing error, the hearing for Part 3 is rescheduled for October 18, 2023. See the notice of rulemaking hearing below for additional information.

Notice of rulemaking hearing for radiation regulations part 3.

The proposed changes to this regulation updates an existing provision, and introduces a new general license section relating to antiquity items containing radium-226. Radium-226 was incorporated into some consumer and other products in the early 1900’s and later. These antiquity items may include watches, clocks, gauges used in military vehicles, revigator jars or urns, small radium calibration sources, all of which may contain radium-226.

The addition of this language to the rule is expected to be an overall benefit to stakeholders and others who have or intend to possess antiquity items containing radium-226. The proposed change will provide a general license path that does not currently exist in Colorado regulation. The changes being proposed have been in federal rule and the regulations of many other states for a number of years.
