Environmental Protection Plan Eastern Mainline Pipeline Project October 2014 1.0 INTRODUCTION This Environmental Protection Plan (EPP) outlines environmental protection measures to avoid or reduce potential adverse effects during construction of the Eastern Mainline Pipeline Project (the Project), proposed by TransCanada PipeLines Limited (TransCanada, the Company). The Project is located in southeastern Ontario and follows the existing TransCanada pipeline right-of-way (ROW) for the Canadian Mainline, which roughly parallels the northwest side of Highway 401. The Project involves the construction and operation of a new buried pipeline and related components to transport natural gas. The pipeline is approximately 245 kilometres (km) in length and has a 914 millimetre (mm) (36 inch) outside diameter (OD) (nominal pipe size (NPS) 36) and four distinct sections. Related components include 15 valve sites and new compressor unit additions at five existing compressor stations (co-located) along the route. The Project will extend from TransCanada’s Mainline Valve (MLV) 132 near the City of Markham, east to MLV 145A of the Canadian Mainline near the community of Iroquois in the Township of South Dundas. The Project footprint required for construction consists of both permanent ROW and temporary workspace (TWS). The Project generally requires a construction ROW of 42 metres (m); however, this ROW width will vary based on site-specific factors. To the extent possible, TransCanada has aligned and overlapped the Project along the Canadian Mainline ROW or other linear disturbances such as pipelines, roads and electrical power lines, to reduce the requirement for new permanent ROW. The Project parallels existing disturbance considered contiguous by the National Energy Board (NEB) (i.e., parallel to an electrical transmission line, oil or gas pipeline, railway or all-season public highway) for approximately 195 km or 79.4 percent (%) of the ROW. In addition to the permanent ROW, the Project footprint includes TWS at staging areas, side bends, highway, railway, road, pipeline and watercourse crossings, where grading is necessary, and at other locations to accommodate safe pipeline construction activities. Temporary infrastructure, such as access, stockpile sites and contractor yards will be required during construction. Some new permanent access may be required for pipeline operations. New electrical power transmission lines and facilities constructed, owned and operated by third party power providers might also be required to operate the new compressor unit additions and cathodic protection sites. Design, construction and operation of the pipeline will be in compliance with all applicable codes, standards and regulations. This EPP outlines environmental protection measures during construction and operations of the pipeline and related components including valve sites and temporary infrastructure required for the Project. Separate EPPs have been prepared for the construction of new and modified compression facilities co-located at five existing compressor stations along the ROW. The EPP is written in construction specification format and should be read in conjunction with the Environmental Alignment Sheets (Appendix C of the Environmental and Socio-economic Assessment [ESA]), as well as the Eastern Mainline Compressor Stations EPP. This EPP provides Project-related environmental mitigation measures and commitments to be addressed during the detailed pipeline engineering design, construction and post-construction reclamation phases. The EPP is based on: • TransCanada’s Health, Safety and Environment (HSE) Commitment; • TransCanada’s HSE Management System; • feedback obtained through consultation and engagement; • results of the biophysical field programs; • commitments made in the ESA; and, • professional experience. Page 1 PDF Page 5 of 216 TransCanada PipeLines Ltd. Environmental Protection Plan Eastern Mainline Pipeline Project October 2014 Revisions to the EPP may occur as a result of: • results of supplemental studies; • commitments made during the regulatory review process including information requests (IRs); • National Energy Board (NEB) Certificate of Public Convenience and Necessity Conditions; and, • engagement programs with Aboriginal communities and other stakeholders. Subject to regulatory approvals, pipeline construction is scheduled to commence in Q2 2016 with the pipeline scheduled to be in-service, and the operations phase to commence at the end of Q1 2017. Clean-up and post-construction reclamation of disturbed portions of the ROW will be conducted immediately
