Proposed activities associated with the Line 2 modifications project component at the Manitou Station include relocation of the DRA skid. SUMMARY OF BIOPHYSICAL AND SOCIO-ECONOMIC ELEMENTS AND CONSIDERATIONS FOR THE MANITOU STATION MODIFICATIONS Biophysical and Socio-Economic Elements Summary of Considerations Physical Environment • Manitou Station lies within the Souris Plain Subdivision of the Western Upland Physiographic Division (Barto and Vogel 1978). • The site is underlain by the Coulter Member of the Riding Mountain Formation. The Coulter Member is characterized by soft grey bentonitic clayey siltstone and shale (Manitoba Mineral Resources Division 1979). • There are no areas of permafrost in the vicinity of Manitou Station (NRC 2006a). • There are no documented major earthquakes, landslides or avalanches in the vicinity of the site (NRC 2006b, c,d). • The topography in the area of Manitou Station is level and the elevation is approximately 1,590 m asl. • The site encounters glacial till composed of calcareous clay diamicton, predominantly derived from Mesozoic shale from above the Manitoba escarpment (Manitoba Land Initiative 2006). • The modifications to Manitou Station will be undertaken within an existing pump station site. Possible sources of soil contamination include spot spills and leaks that may have occurred during past onsite activities. A search of the Federal Contaminated Sites and Solid Waste Landfills Inventory and the Manitoba Contaminated Sites List has revealed no listed contamination at the site (Manitoba Conservation 2002, Treasury Board of Canada Secretariat 2006). • The climate in the area is marked by short, warm summers and long, cold winters with continuous snow cover (Environment Canada 2006b). Soil Capability • The modifications to Manitou Station will be undertaken within an existing fenced industrial site lacking topsoil and, therefore, detailed soil information is not deemed warranted as per Table A-3 of the Filing Manual. • See Physical Environment for potential contaminated soil. Water Quality and • The surface waters in the vicinity of Manitou Station form part of the Pembina River Quantity watershed of the Assiniboine River Basin (Manitoba Agriculture, Food and Rural Initiatives 2006). • No watercourses lie within 30 m of Manitou Station. The nearest watercourse to the site is Mary Jane Creek which is located approximately 2.5 km southwest of the site. • Enbridge has an existing groundwater monitoring system in place at Manitou Station to monitor groundwater quality and quantity. Any ground disturbance associated with the modifications at the site will be limited to shallow depths and are not expected to impact groundwater quality. Contaminants of concern associated with the modifications that may affect water quality, if spilled or leaked, include crude oil, diesel fuel, lubricants and hydraulic fluids. • There is one water well identified within the quarter-section utilized for domestic purposes (Manitoba Water Stewardship 2006). Activities associated with the modifications to Manitou Station are not anticipated to have any effects on well water quantity or quality. • Rental fluids will be used for hydrostatic testing. In the unlikely event that Enbridge will withdraw water for hydrostatic testing, they will follow all applicable provincial regulations. February 2007 4663 Page 5-153 Enbridge Pipelines Inc. Southern Lights Project Enbridge Southern Lights LP Volume II Biophysical and Socio-Economic Elements Summary of Considerations Air Quality • Air quality in the area surrounding Manitou Station is primarily a function of anthropogenic sources of emissions such as those arising from vehicle and rail traffic on adjacent roads and railways and from equipment used for farming. • Manitou Station is located approximately 7 km northeast of Manitou, Manitoba. The nearest residence is located 200 m north of the site. • The modifications to Manitou Station will not result in an increase in measurable airborne emissions during operations or maintenance since the pumps are electrically driven. Acoustic Environment • Current sources of noise emissions in the area surrounding Manitou Station are from vehicle and rail traffic on adjacent roads and railways and from equipment used for farming. • Manitou Station is located approximately 7 km northeast of Manitou, Manitoba. The nearest residence is located 200 m north of the site. • Noise levels at Manitou Station may increase during operation of the LSr pipeline. Fish and Fish Habitat • The activities associated with the modifications to Manitou Station will not impact fish or fish habitat. • The nearest potential fish-bearing watercourse is Mary Jane Creek located approximately 2.5 km southwest of the site. Wetlands • The nearest natural water feature is a wet slough located approximately 300 m west of the site. • There are no wetlands within 30 m of the terminal. Vegetation • Manitou Station is located within the Aspen Parkland Ecoregion of the Prairie Ecozone (Environment Canada 2006b). • The site is located within an existing disturbed and fenced industrial area devoid of vegetation and, therefore, detailed vegetation information is not deemed warranted as per Table A-3 of the Filing Manual. Wildlife and Wildlife • Manitou Station is not located within or near any National Wildlife Areas or Provincial Habitat Wildlife Management Areas, Wildlife Refuges, Migratory Bird Sanctuaries, Important Bird Areas, Ramsar wetlands or World Biosphere Reserves (Environment Canada 2006d, Important Bird Areas of Canada 2006, Bureau of the Convention on Wetlands 2006, UNESCO 2006, Government of Manitoba 2006b, Manitoba Agriculture, Food and Rural Initiatives 2006). • The modifications at Manitou Station will occur within an existing large, previously disturbed industrial site, which is not considered to be suitable wildlife habitat. No impacts to wildlife or wildlife habitat are expected to occur as a result of the pump station modifications. Species at Risk or • The modifications at Manitou Station will occur within an existing large, previously Species of Special disturbed industrial site, which is not considered suitable habitat for wildlife or plant Status species at risk. Nevertheless, depending on the surrounding land use, construction activities at the site could disturb wildlife SARA-listed species within 500 m of the terminal. Manitou Station lies within the home range of the following SARA-listed species: least bittern (lxobrychus exilis), loggerhead shrike (Lanius ludovicianus excubitorides); sprague's pipit (Anthus spragueii); yellow rail (Coturnicops noveboracensis); northern leopard frog (Rana pipiens); and monarch (Danaus plexippus) (Environment Canada 2006c). It is anticipated that only bird SARA-listed species utilizing the pasture lands within 500 m of the site have the potential to be disturbed by construction activities. • Waiting on response from the MB CDC regarding any plant or wildlife species of concern in the vicinity of the pump station (MB CDC 2006b). February 2007 4663 Page 5-154 Enbridge Pipelines Inc. Southern Lights Project Enbridge Southern Lights LP Volume II Biophysical and Socio-Economic Elements Summary of Considerations Human Occupancy • The existing Manitou Station is situated on lands owned by Enbridge. Adjacent lands and Resource Use are privately-owned and are primarily used for farming. The site is located on lands administered by the RM of Pembina No. 161 that have been zoned as Agricultural General (Rural Municipality of Pembina No. 161 2004). The proposed facilities are compatible with zoning at this site. • The pump station does not encounter: rural or urban residential areas; Indian Reserves or Aboriginal communities; recreation and park areas; lands under Parks Canada jurisdiction or conservation areas, controlled or managed forest areas; water reserves and licenses or water intakes or land and water based transportation infrastructure. The pump station is not adjacent to any Environmentally Significant Areas, proposed or existing parks, Ecological Reserves, Provincial Recreation Areas, designated Wilderness or Natural Areas (Indian and Northern Affairs Canada 2006, Government of Manitoba 2006b, Manitoba Agriculture, Food and Rural Initiatives 2006). The International Biological Program is no longer active. • The pump station is situated an existing industrial site on private lands next to several roads and, as such, it is unlikely that any hunting and guiding occurs next to the terminal. All hunters require permission from the landowner. • Due to the large proportion of land in private ownership and under industrial use and cultivation surrounding the pump station, recreational use of the lands around this location is limited. There are no provincial parks, recreation areas or environmentally significant areas within close proximity to the site. • There is water well identified within the quarter-section utilized for domestic purposes (Manitoba Water Stewardship 2006). • The modifications to Manitou Station will entail the construction of new pumps building and sump systems and the installation of a DRA skid which may be considered an aesthetic impact.
