Part 9 Rulemaking
Notice of public rulemaking hearing for Radiation Regulations Part 9
Part 9 request for rulemaking package to be presented at the August 21, 2024 Board of Health Meeting.
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 9, titled “Radiation control – Radiation safety requirements for particle accelerators not used in the healing arts”. The primary proposed changes will correct minor typographical errors, update the section on documents incorporated by reference, add clarifying language, and improve consistency with national model regulations.
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 June 4, 2024 and ends on July 5, 2024. Stakeholders are invited to provide written comments on the proposed regulations to cdphe_CORadRegs@state.co.us on or before July 5, 2024.
Due to the minor nature of the proposed changes, we are not scheduling any stakeholder meetings for this rulemaking. We encourage stakeholders to submit comments in writing or contact the radiation program staff for additional information. Find staff contact information on the rulemaking schedule.
