1.1 Aim

The aim of the Provincial Nuclear Emergency Response Plan (PNERP) Implementing Plan for the Darlington Nuclear Generating Station (DNGS) is to describe the measures that should be undertaken to mitigate the off-site effects of a nuclear emergency at DNGS.

1.2 Scope

1.2.1 This implementing plan shall be read and applied in the context of the PNERP Master Plan.

1.2.2 In case of any apparent differences between the provisions of the PNERP Master Plan and this Implementing Plan, the latter being more detailed and specific is applicable.

1.2.3 Together, these two plans focus on provincial level actions and should therefore be supplemented by the appropriate municipal plans and other supporting plans and procedures (see Sections 1.3 and 1.4 below).

1.2.4 OFMEM shall establish and communicate guidance to verify stakeholder conformance with the PNERP Master Plan and this Implementing Plan.

  2. Representatives of the OPP, Metrolinx, Regional Municipality of Durham, local police services, road authorities and emergency services shall cooperate with MTO in the development and maintenance of the UTMP and in its implementation during a nuclear emergency response through the Unified Transportation Coordination Centre (UTCC).

1.4.5 Provincial Liquid Emission Response Plan (PLERP)

The PLERP for DNGS is an organizational plan issued by the MCSCS (OFMEM) to mitigate the effects of a waterborne release from a reactor facility resulting in discharges with above normal levels of radioactivity. Additional guidance on the application of the PLERP coincident with a nuclear emergency is provided in Section 6.10.
