Canadian Nuclear Safety Commission invites comments on draft REGDOC-2.5.4, Design of Uranium Mines and Mills: Ventilation Systems (formerly G-221)

News Release

October 4, 2017 – Ottawa, ON
The Canadian Nuclear Safety Commission (CNSC) is asking the public, Indigenous Peoples and stakeholders to provide comments on draft REGDOC-2.5.4, Design of Uranium Mines and Mills: Ventilation Systems, (formerly G-221, A Guide to Ventilation Requirements for Uranium Mines and Mills), by November 15, 2017. Comments submitted, including names and affiliations, will be made public.

REGDOC-2.5.4, Design of Uranium Mines and Mills: Ventilation Systems, provides guidance on addressing the requirements for submitting ventilation-related information when applying for a CNSC licence to prepare a site for and construct, operate or decommission a uranium mine or mill. This regulatory document is also intended to help applicants for a uranium mine or mill licence understand their operational and maintenance obligations for ventilation systems, and to help CNSC staff evaluate the adequacy of applications for uranium mine and mill licences.

Section 2, Environmental and Licensing Processes, of draft REGDOC-2.5.4 contains content that has been updated since the publication of G-221. Draft REGDOC-2.5.4 also incorporates administrative changes to align existing content with new CNSC nomenclature for regulatory documents.
If approved, REGDOC-2.5.4 will replace G-221, which was published in June 2003.

This consultation process includes a request for information, which is specific to draft REGDOC-2.5.4 and outlines the document’s regulatory objectives and approach, as well as the estimated impacts on stakeholders. The public is asked to provide clear and specific feedback to help CNSC staff refine or revisit initial assumptions and objectives.

To review and comment on draft REGDOC-2.5.4 and the request for information, visit the REGDOC-2.5.4 Web page.
 
The CNSC regulates the use of nuclear energy and materials to protect health, safety, security and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
