Near Surface Disposal Facility Project
The Impact Assessment Act (IAA) came into force August 28, 2019. Ongoing projects with environmental assessments initiated under the Canadian Environmental Assessment Act, 2012 (CEAA 2012) and led by the CNSC, will continue under their current processes. The IAA contains provisions to enable these projects to advance in this way.
Visit the Canadian Impact Assessment Registry (CIAR) website for all information and documentation related to the project.

About the project
The Near Surface Disposal Facility (NSDF) is a proposed engineered disposal facility for low level radioactive waste planned for the Chalk River Laboratories site (CRL). All waste to be disposed at the NSDF will be required to meet the waste acceptance criteria established to assure compliance with operational and long-term safety requirements.
The CRL site is located in Renfrew County, ON, on the shore of the Ottawa River, approximately 200 km northwest of Ottawa. The site is situated within the boundaries of the Corporation of the Town of Deep River.
The NSDF is planned to have an operating life of at least 50 years and as proposed, would be an engineered mound built at near-surface level on the CRL site. The engineered mound would be cellular, made up of multiple disposal cells consisting of:
- base liner and final cover systems
- leachate collection and leak detection systems
- environmental monitoring systems
The proposed project would also include:
- a wastewater treatment plant
- supporting infrastructure, such as a truck wheel wash, vehicle monitoring and weighing stations, work stations and change facilities, security systems to monitor access and egress, construction trailers, and marine containers or tents for storage of construction materials
Under the Nuclear Safety and Control Act, CNL’s proposal requires approval by the CNSC and involves an amendment to the CRL Nuclear Research and Test Establishment Operating Licence. An EA conducted under the Canadian Environmental Assessment Act, 2012 is required, and an EA decision affirming that the proposed activities will not cause significant adverse environmental effects, before the CNSC can make a licensing decision on this proposal.
The public registry for this project is maintained on the CIAR. If you wish to receive email notifications when the CNSC’s website is updated, including notices for hearings, meetings and PFP funding opportunities, subscribe to the CNSC mailing list.
