A Wholly Owned Subsidiary of TransCanada PipeLines Limited 450 - 1st Street SW Calgary, AB T2P 5H1 Report Number: 1313340056-5000/5001 Distribution: REPORT 1 copy TransCanada PipeLines Limited Calgary, AB 1 copy Golder Associates Ltd. Calgary, AB MCDERMOTT EXTENSION, CALUMET RIVER SALES AND CALUMET RIVER NO. 2 SALES METER STATIONS PROJECT Executive Summary NOVA Gas Transmission Ltd. (NGTL), a wholly owned subsidiary of TransCanada PipeLines Limited (TransCanada), is applying to the National Energy Board (NEB) under section 58 of the National Energy Board Act (NEB Act) for an order to authorize construction and operation of the McDermott Extension, Calumet River Sales and Calumet River No. 2 Sales Meter Stations (the Project). NGTL retained Golder Associates Ltd. (Golder) to prepare this Environmental and Socio-economic Assessment (ESA) to meet the requirements and guidance of the NEB, including the NEB Filing Manual (NEB 2014a). This ESA report is submitted to the NEB as part of NGTL’s section 58 Application for the Project. The Project is located entirely on Crown land in the Green Area of Alberta, in the Regional Municipality of Wood Buffalo, approximately 20 kilometres (km) north of Fort McKay, Alberta. The Project will include approximately 7.9 km of nominal pipe size (NPS) 20 inch pipeline to transport sweet natural gas from the existing Ells River Extension pipeline located in SE 22-96-11 W4M to two new Calumet River Sales Meter Stations (Calumet River Sales Meter Station and Calumet River No. 2 Sales Meter Station) located in SW 6-97-10 W4M. The Project parallels approximately 5.6 km of TransCanada’s wholly owned subsidiary Northern Courier Pipeline GP Ltd.’s Northern Courier Pipeline Project and crosses the Athabasca River. NGTL proposes to use existing commercial and camp accommodations to house the temporary Project construction personnel. The Project parallels existing disturbance considered contiguous by the NEB (i.e., parallel to an electrical transmission line, oil or gas pipeline, railway or all-season public highway) for approximately 5.6 km or 71 percent (%) of the route. The Project footprint required for construction consists of new permanent right-of-way (ROW) and temporary workspace (TWS). By using TWS on an existing ROW, the need for new ROW is minimized; this also results in a variable ROW width depending on the existing ROW paralleled. The minimum ROW width required for safe and efficient construction will be 27 metres (m), which includes 20 to 27 m of new permanent ROW. TWS is required at highway, road, pipeline and watercourse crossings, log deck sites, truck turnarounds, and other locations to accommodate safe pipeline construction activities (e.g., grading). The Project crosses forested land, wetlands, and one watercourse, the Athabasca River, which is approximately 737 m wide (bankfull width) and the valley approximately 35 m deep at the planned crossing location. The watercourse crossing is planned to be constructed by horizontal direction drilling (HDD) as other typical crossing methods (e.g., isolated open-cut) are not considered feasible due to the width and depth of the watercourse. An open-cut contingency crossing design has been prepared for discussion with regulators and use, if required. No new temporary or permanent access is planned to support construction or operation of the Project. Access to the Project during construction will be primarily by existing highways and public roads, industry access roads, pipeline ROW, and the proposed Project ROW. The Project footprint of 24.6 hectares (ha) is dominated by approximately 14.0 ha (57% of the Project footprint) of existing disturbance (e.g., disturbed land, revegetated industrial land), with 3.5 ha (14% of the Project footprint) of undisturbed upland vegetation, and 7.1 ha (29% of the Project footprint) of wetlands, all of which are November 2014 Report No. 1313340056-5000/5001 MCDERMOTT EXTENSION, CALUMET RIVER SALES AND CALUMET RIVER NO. 2 SALES METER STATIONS PROJECT peatland (organic) wetlands. The Project crosses Key Wildlife and Biodiversity Zone (KBWZ) for approximately 7.4 km (94.1%) of the pipeline route. The design, construction and operation of the Project will comply with all applicable codes, standards and regulations. Subject to regulatory approval, construction is scheduled to commence with the Project HDD watercourse crossing in September 2015 and the Project pipeline and facility construction in November 2015, with an expected in service date of April 2016. It is anticipated that some activities will be necessary during the Restricted Activity Period, January 15 to April 30, for the KWBZ. A KWBZ Protection Plan to address this potential occurrence was developed in consultation with and submitted to Alberta Environment and Sustainable Resource Development, and will be finalized prior to construction. Preparation of the ESA included desktop studies, which were conducted for all environmental and socio- economic elements considered in the effects assessment, and field studies for specific elements. Appropriately timed field studies were conducted in 2013 and 2014 for the following environmental elements: wildlife surveys, including reconnaissance level, remote camera, amphibian, yellow rail and breeding bird surveys; vegetation and wetlands surveys, including reconnaissance level, listed plants, and noxious weeds surveys; and aquatic and fish habitat surveys, including watercourse crossing location surveys. Golder did not conduct field based activities (e.g., helicopter flyovers, Traditional Land and Resource Use [TLU] community sessions, or ground-based surveys) in relation to TLU specifically for the Project. However, individuals from two communities participated in Golder-led biophysical and cultural field studies in August 2014. Based on desktop investigation presented in the Statement of Justification submitted for the Project, Alberta Culture advised that no further palaeontological investigation was required. A Historical Resources Impact Assessment (HRIA) completed for the Project determined that the Project encounters no previously recorded historic resource sites or structures, and a recommendation was made in the HRIA final report that clearance under the Alberta Historic Resources Act be granted for the Project. The socio-economic assessment considered the traditional, recreational and industrial activities occurring in the Regional Municipality of Wood Buffalo. The potential effects on communities, including Aboriginal communities, and on infrastructure and services, were assessed based on introducing the Project workforce, which is expected to reach 120 persons at the peak of construction. The potential environmental effects associated with the Project are those typically encountered during pipeline and meter station construction and operation in a forested setting in the Green Area of Alberta. Similarly, potential socio-economic effects are those typically identified in association with pipeline and facility construction projects in northern Alberta. Project-specific mitigation will be implemented by NGTL to avoid or reduce potential adverse effects during construction and operation. The environmental protection measures designed to mitigate potential environmental effects are presented in the Environmental Protection Plan (Appendix A) and on the Environmental Alignment Sheets (Appendix B) of this ESA. Mitigation as set out in this ESA will also be implemented to alleviate potential adverse socio-economic effects, and will include safety protocols, accepted industry construction and operations November 2014 Report No. 1313340056-5000/5001 MCDERMOTT EXTENSION, CALUMET RIVER SALES AND CALUMET RIVER NO. 2 SALES METER STATIONS PROJECT standards, adherence to all applicable regulations, as well as order and permitting conditions, and ongoing consultation with Aboriginal communities and other stakeholders. The design and implementation of TransCanada’s environmental compliance strategy – including environmental protection planning and implementation, environmental inspection and monitoring, and post-construction monitoring and follow-up – is expected to avoid or mitigate potential adverse environmental and socio-economic effects as a result of the Project. Assessment of the potential environmental and socio-economic effects resulted in the prediction that any adverse residual Project-related effects will be not significant. The Project is expected to act cumulatively with existing and foreseeable future developments, including transportation, oil and gas, and forestry. The cumulative effects from existing and approved developments on wildlife and wildlife habitat in the terrestrial regional study area represent a management concern for all wildlife key indicators. Consequently, the cumulative effects on the wildlife and wildlife habitat valued component are considered to be significant. Cumulative effects in the region on all other valued components considered in the cumulative effects assessment are predicted to be not significant. These cumulative effects exist within the context of the Lower Athabasca Regional Plan and regional
