Part 4 Rulemaking

We are holding a stakeholder process to engage and notify stakeholders about proposed changes to the Colorado Rules and Regulations Pertaining to Radiation Control, 6 CCR 1007-1, Part 4, titled “Standards for protection against radiation”.

This rulemaking proposes to make changes to Part 4 by revising 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, minor editorial and formatting corrections and changes for consistency with other current radiation regulations are being updated in Part 4.

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

• The Part 4 draft proposed rule (April 2023).
• Part 4 detailed summary.
• The Part 4 complete rulemaking schedule.

Stakeholder comment period

A stakeholder comment period for the Part 4 regulation begins on April 24, 2023 and end on May 29, 2023. Stakeholders are invited to provide written comments on the proposed regulations to cdphe_CORadRegs@state.co.us on or before May 29, 2023.

We held stakeholder meetings to present and discuss the proposed changes, and receive feedback on May 17, 2023 and May 24, 2023.

Part 3 Rulemaking for radium-226 antiquities

We are holding a stakeholder process to engage and notify stakeholders about proposed changes to the Colorado Rules and Regulations Pertaining to Radiation Control, 6 CCR 1007-1, Part 3, titled “Licensing of radioactive material”. 

The proposed changes to this regulation will update an existing provision, and introduce a new general license section relating to antiquity items containing radium-226. Radium-226 was introduced 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. 

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

• Part 3 draft proposed rule (April 2023).
• Part 3 Radiation Regulations radium-226 summary
• Part 3 detailed summary document.
• Part 3 frequently asked questions (FAQs) document. 
• Part 3 complete rulemaking schedule.

Stakeholder comment period

A stakeholder comment period for the Part 3 regulation begins on or about April 10, 2023 and ends May 15, 2023. Stakeholders are invited to provide written comments on the proposed regulations to cdphe_CORadRegs@state.co.us on or before May 15, 2023.

We held stakeholder meetings to present and discuss the proposed changes, and receive feedback on April 26, 2023 and May 4, 2023.
