Summary
Regulatory document REGDOC-2.9.2, Controlling Releases to the Environment, clarifies the CNSC’s requirements and provides guidance for controlling releases to the environment, through:
- applying the concept of best available technology and techniques economically achievable
- establishing and implementing licensed release limits and action levels for releases to the environment
- commissioning a treatment system and confirming system performance
- implementing adaptive management where required
This is the first published version of this regulatory document. It is meant to be used in conjunction with REGDOC-2.9.1, Environmental Principles, Assessments and Protection Measures.
These requirements and guidance apply to licence applications for proposed new nuclear facilities or activities and applications for licence renewals and amendments. This document will also be used to assess a licensee’s environmental protection measures when a potential for unreasonable risk has been identified and adaptive management is required.
Early engagement with CNSC staff is encouraged for facilities or activities with potential interactions with the environment or where there is uncertainty regarding the potential for interaction with the environment. CNSC staff can provide facility- or activity-specific guidance to assist applicants and licensees.
For information on the implementation of regulatory documents and on the graded approach, see REGDOC‑3.5.3, Regulatory Fundamentals.
