1.0 INTRODUCTION
Kinder Morgan Canada Inc. (KMCI), formerly Terasen Pipelines Inc., is operator of Terasen Pipelines (Trans Mountain) Inc. (“Terasen Pipelines”). The Trans Mountain Pump Station Expansion Project (TMPSEP) will increase the capacity of its existing National Energy Board (“NEB”) regulated oil pipeline system (the ʺTrans Mountain pipelineʺ or ʺTrans Mountainʺ).
The Project involves:
• modifications to 14 existing stations or facilities (Edmonton (KP 0.0), K19 (KP 20), K21 (KP 21), Gainford (KP 99.4), Niton (KP 173.4), Edson (KP 228.7), Jasper (KP 369.5), Albreda (KP 519.1), McMurphy (KP 645.0), Darfield (KP 742.0), Kamloops Petro‐Canada Take‐off (K818) (KP 817.4), Kamloops (KP 822.0), Kingsvale (KP 924.8) and Sumas (KP 1082.0);
• construction of six new stations on existing lands owned by Terasen Pipelines (Stony Plain (KP 49.5), Hinton (KP 317.7), Rearguard (KP 476.8), Blackpool (KP 709.9), Hope (KP 1011.8) and Wahleach (KP 1045.9); and
• construction of four new pump stations on lands newly acquired by Terasen Pipelines at Chip (KP 147.1), Finn (KP 612.5), Stump (KP 862.7), and Port Kells (KP 1124.3).
Ten of the 24 pump stations are located in Alberta and 14 are located in British Columbia (BC) within commercial/industrial, agricultural, or forested settings. Although new stations at Merritt (KP 900.8) and Juliet (KP 949.8) were considered as part of the TMPSEP application to the NEB, these stations have been subsequently removed from TMPSEP.
Construction at the pump station sites is scheduled to commence in March 2006, and extend until April 2007 depending on the site and scope of Project activities. A summary of the work to be undertaken at each pump station is provided in Table 1. Clean‐up will be conducted immediately following construction or as soon as soil and weather conditions permit.

Weed Control / Stony Plain, Chip, • Ensure all construction equipment arrives on the construction Introduction Hinton, Rearguard, site in a clean condition to minimize the risk of weed Albreda, Finn, introduction. Any equipment that arrives in an unclean Blackpool, Stump, condition shall not be allowed on the site until it has been Hope, Wahleach, Port cleaned off at a suitable location. Kells • Monitor weed growth on topsoil piles during the course of construction and corrective measures (i.e., spraying) will be conducted if warranted. Mountain Pine Beetle Rearguard • Conduct a site evaluation prior to clearing to determine Infestation whether trees at the Rearguard site have mountain pine. Schedule the assessment to occur after the beetle flight period (i.e., after September 15) and no later than March 2006. Migratory Birds Stony Plain, Hinton, • Preclear timber and mow tall vegetation from construction Rearguard, Albreda, areas as early as practical in spring (prior to April 1 or May 1 Finn, Blackpool, if feasible) to discourage nesting at the construction site. Wahleach, Port Kells Conduct a migratory bird nesting survey in 2006 if activities occur during the May 1 to July 31 (Stony Plain to Finn stations) or April 1 to July 31 (Blackpool to Port Kells stations) timing constraint and the site has not been precleared / premowed. Stump • Preclear timber from construction areas as early as practical in spring (prior to April 1 if feasible) to discourage nesting at the construction site. Conduct a migratory bird nesting survey in 2006 if activities occur during April 1 to August 31 timing constraint and the site has not been precleared. Wildlife Habitat Hinton • Avoid alteration or siltation of the anthropogenic wetland. Install silt fence prior to construction. • Stake and flag identified exclusion area that contains a wetland and habitat for amphibians to prevent encroachment by workers, weed control and construction activities. • Fence ditches or trenches to avoid amphibians and other wildlife fall in. • Leave coarse woody debris on the periphery of the Hinton Pump Station that will not be disturbed and areas immediately surrounding the anthropogenic wetland to maintain habitat features for the long-toed salamander.
