2.2.3.1 M&NP OptionThe proposed pipeline route for the M&NP Option extends 173 km and closely follows the existingSOEP gas pipeline. With the exception of a slight route change offshore due to the revised location ofthe field centre, the offshore pipeline routing for this option remains unchanged from the route outlinedin the approved 2002 CSR.2.2.3.2 SOEP Subsea OptionThe export pipeline to the SOEP Subsea Option tie-in point will be approximately 15 km in length. Thewater depth ranges from approximately 20 m to 45 m in depth and the seabed is relatively featureless. Itis anticipated that the pipeline for SOEP Subsea Option will be buried. The pipeline will traverse aregion of Sable Island Bank noted for its heterogeneous surficial geological characteristics. Thedominant substrates along the proposed route are well-sorted Sable Island sand and, to a lesser extent,gravel. Sand ripples and mega-ripples are common due to the influence of waves and currents. Thesurficial sediments of the pipeline route are under the influence of dynamic sediment transport regimes,with large volumes of sand moved during storm events. In contrast to the M&NP option, the SOEPSubsea Option pipeline will not traverse areas of rock outcroppings, basins or other notable geologicalfeatures.2.2.4 Onshore Pipeline and FacilitiesOnshore facilities are required for the M&NP Option only. In this option, EnCana’s onshore facilitywill consist of the physical components necessary for interconnection of EnCana’s natural gas pipelinewith M&NP’s facility. EnCana will install a pig launcher/receiver facility and a safety/emergencyshutdown valve system. The onshore facility will interface with the M&NP owned facility, which willinclude custody transfer meters, the final section of pipeline, and the tie-in to the existing M&NPpipeline. This facility is estimated to be 60 m x 45 m in area and will be enclosed by a security fence.The onshore pipeline will be located within the pipeline corridor indicated on Figure 2.6.Deep Panuke Volume 4 (Environmental Assessment Report)• November 2006 2-10
