Draft Scoping Information Document - Ontario Power Generation

July 2011
Draft Scoping Information Document - Proposal by OPG - Refurbishment and
Continued Operation - Darlington Nuclear Generating Station, Clarington, Ontario
3. PROJECT-SPECIFIC INFORMATION REQUIREMENTS
3.1 Project Overview and Schedule
The EIS must identify and characterize the undertakings and the activities in
relation to those undertakings that are required for the proposed project. An
overview of the proposed project, together with a proposed schedule for all phases
of the project is required.
3.2 Proponent Organization
The EIS will include a detailed description of OPG, including its ownership,
organization and structure. This description will also include the relevant
organizational and management structure, and staff qualification requirements
with emphasis on safety and environmental management programs.
3.3 Purpose of the Project
The “purpose of” the project is defined as what is to be achieved by carrying out
the project. The screening report will provide a clear and comprehensive
statement of the purpose of the project.
The need for the electricity to be generated by OPG would involve consideration
of broader public policy issues that are under the authority of the Province of
Ontario and over which the CNSC has no regulatory authority. Consequently this
matter is not within the scope of this EA.
Similarly, the separate questions of “alternatives” to the project for generating
electricity such as by building a hydroelectric facility or conserving energy are
matters under the authority of the Province of Ontario and are beyond the CNSC’s
legislated mandate and control under the NSCA. Furthermore, this is an EA for a
specific project, rather than for a policy direction. “Alternative means” of carrying
out the project such as location, or alternative means of refurbishing components
are not relevant given DNGS is an existing facility of a particular design.
3.4 Physical Components and Activities of the Project
An adequate description of the project is necessary to permit a reasonable
consideration in the screening of the environmental effects of the project. The
main objective of the project description is to identify and characterize those
specific components and activities of the project that have the potential to interact
with, and thus result in a likely change or disruption to the surrounding
environment, during normal operations and during malfunctions and accidents.
The description of the project will include and elaborate upon, the items identified
in the project scope, supported with appropriate maps and diagrams.
The description of the project will include a proposed schedule for the staged
restart and return to service of the DNGS units. To ensure a conservative
assessment approach, it should be assumed that all four DNGS reactor units will
