M6.2-1 Implementation of TERMPOL Recommendations Residual Project effects on commercial and non-commercial marine area use and access are assessed to be not significant. The South Arm of the Fraser and specifically the LAA is a highly industrialized area, whereby commercial and non-commercial users are familiar with in-river construction and operational activities and associated marine transportation vessel transiting. If residual effects occur, commercial and non-commercial marine use activities would continue to have access to use areas within the LAA, and would experience temporary effects to access and use from the Project. Supporting management plans along with marine systems (e.g., communication and navigational aids), will further assist support users’ capacity to respond to effects as reflected by the low magnitude of the predicted residual effects.

15.2 Summary of Mitigation Measures The mitigation measures presented in the WesPac Tilbury Marine Jetty Project (Project) Application for an Environmental Assessment Certificate (Application) are summarized below in Table 15-2. These measures were developed to avoid, minimize, restore onsite, or offset the potential adverse effects of the Project on environmental, economic, social, heritage and health pillars as discussed in Part B of the Application.
The mitigation measures are organized in the table by Pillars and Valued Component (VC). Each mitigation measure was given a unique identification number corresponding with the first section of the Application in which it appeared. As the same mitigation measure may apply to more than one VC or Pathway Component (PC), the measure is fully described in the first section in which it appears, and thereafter referenced by number and name. Project design measures or other measures that mitigate the potential effects, in addition to the mitigation measures in the table, are summarized in each VC and PC assessment. Project phase refers to the phase during which Project-related effects will be mitigated by the measure (i.e., Construction, Operation, and Decommissioning). Timing refers to when the mitigation measure will be developed or implemented.
WesPac Midstream —Vancouver LLC (Proponent or WesPac) will also develop the plans required for permitting by the Oil and Gas Commission (OGC), including an Emergency Response Plan. WesPac will implement the Project design, management and contingency measures noted in Section 9.0 Accidents and Malfunctions. In addition, the Proponent will prepare and implement the plans presented in Section 14.0 Management Plans, which will incorporate the mitigation measures in Table 15-2 and monitoring and follow-up programs into Construction, Operation and Decommissioning Environmental Management Plans.
