4 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project 1.0 INTRODUCTION AND PROJECT DESCRIPTION On December 20, 2010, NOVA Gas Transmission Ltd. (NGTL), a wholly owned subsidiary of TransCanada PipeLines Limited (TransCanada), received National Energy Board (NEB) approval, pursuant to Section 58 of the NEB Act XG-N (NEB 2010), for the construction and operation of the Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project (the Project). The Project is located in northwest Alberta, approximately 30 km southwest of Grande Prairie, Alberta. The Project consisted of the construction of approximately 38 km of new 610 mm O.D. (NPS 24) pipeline (Figure 1, Appendix A). The Project utilized a 25 m wide construction right-of-way (ROW), consisting of 12 m of existing right-of-way and 13 m of new permanent ROW when paralleling an existing ROW or 25 m of new permanent ROW when existing ROW was not available. Additional temporary workspace was utilized at select locations to accommodate construction activities (for example road crossings, pipeline and watercourse crossings, sharp sidebends, steep sidehills, log decking sites). The Project route is contiguous with existing linear disturbances (e.g., seismic lines, pipelines and roads) for approximately 32.8 km (88%) of its length. Construction began in January 2011 and was completed in April Final clean-up was completed in October NGTL has committed to a Post-Construction Monitoring (PCM) Program for the construction ROW during the first, third and fifth complete growing seasons following the commencement of operation of the Project. On or before 31 January after each of the first, third, and fifth complete growing seasons following the commencement of operation of the Project, NGTL shall file with the Board a post-construction environmental monitoring report that: a) describes the methodology used for monitoring, the criteria established for evaluating success and the results found; b) assesses the effectiveness of the mitigation measures applied during construction against the criteria for success; c) identifies any deviations from plans and alternate mitigation applied as approved by the Board; d) identifies locations on a map or diagram where corrective action was taken during construction and the current status of corrective actions; and e) provides proposed measures and the schedule NGTL shall implement to address any unresolved concerns. This report presents the results of the fifth year PCM program conducted in January 2017 Page 1

5 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project 1.1 Environmental Setting The Project is located within the Crown-owned Green Area of Alberta within the Central Mixedwood Subregion and the Lower Foothills Subregion of Alberta (Natural Regions Committee 2006). The Project is located within the Regional Municipality of Greenview (Municipal District 16). The pipeline route crosses Bald Mountain Creek, a Class C watercourse, 12 unnamed tributaries to Bald Mountain Creek, 5 unnamed tributaries to Cutbank River and two wetlands. Key environmental issues identified in the Environmental and Socio- Economic Assessment (ESA) prepared for the Project include: issues relating to soil erosion control; potential effects on downstream water quality; potential introduction and spread of weeds; potential increase in the spread of bark beetles; incremental loss of remnant native vegetation; and potential effects on wildlife. 1.2 Construction Summary Construction activities were guided by the Project Environmental Protection Plan (EPP). Clearing activities began in January Merchantable timber was salvaged and non-merchantable timber was mulched and/or burned depending on timber densities. Immediately following clearing, grading activities commenced. Snow bridges were constructed to cross all watercourses along the route, with the exception of Bald Mountain Creek (SW W6M), which utilized a clear span bridge. Trenching was conducted from February to April The Contractor utilized a combination of track hoes and ditching wheels to excavate the trench line. All watercourse crossings were installed utilizing an isolated open cut or open cut methodology depending on the presence or absence of water. Immediately following the installation and backfilling of the trench at watercourse crossings, the banks were stabilized and reclaimed to pre-construction contours utilizing bioengineering techniques. Final tie-ins and rough clean-up occurred from March to mid-april The pipeline trench was crowned with material from the trench excavation to allow for settlement through spring Cross right-of-way drainages were installed at applicable locations, grade cuts were replaced, access was removed, and erosion and sedimentation control measures were installed in preparation for 2011 spring breakup. Due to the late start of the Project, a small portion of the right-of-way was unable to be fully cleaned up prior to the onset of spring conditions. This area was stabilized and the necessary erosion and sediment control structures were installed prior to spring break-up. In spring 2011, several inspections were conducted to monitor conditions on the ROW, ensuring erosion and sediment controls installed were functioning properly. During the second inspection in August 2011, following a 1:100-year rain event, January 2017 Page 2

6 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project erosion was noted on the pipeline ROW at Bald Mountain Creek. Water levels rose above the south bank and removed m of cover from on top of the ROW. Bank stabilization techniques functioned as designed and maintained the integrity of the banks through this abnormal rainfall event. Following the rain event, in consultation with the regulating authorities, NGTL installed rock armouring along the north and south banks to prevent future scouring to protect the existing pipeline. Additional bioengineering techniques were employed on top of the south bank to facilitate accelerated vegetation establishment and prevent erosion. In August 2011, a ground inspection was conducted by NGTL to assist in the development of a plan for final clean-up. It was determined that the optimal timing for final clean-up to commence was in September A combination of widetracked equipment and snow cats were utilized to work the trench line. Soil material with uneven settlement over the trench line was redistributed and crowned. Cross ROW drainage was returned to pre-construction conditions, where necessary. Grade cut settlement was contoured and the necessary sedimentation and erosion controls were installed. Final clean-up was completed in October In spring and summer 2012, NGTL personnel continued to monitor conditions along the ROW to assess the effectiveness of the mitigation measures employed during the construction of the pipeline. s for remedial actions and monitoring were documented. 2.0 POST CONSTRUCTION RECLAMATION MONITORING (PCRM) PROGRAM NGTL implemented the Project specific PCRM program to address the recommendations of the First Year PCM Program Report. The PCRM program was implemented on the Project in 2013 and included an assessment of the ROW, the completion of minor reclamation activities, and a rare plant survey in August In 2016 the PCRM program built on the work completed in 2013 through to 2015, with additional ROW assessments and the completion of minor reclamation activities, and vegetation control. 2.1 PCRM Objectives The objectives of the PCRM program are to: assess the success of mitigation measures implemented during construction document opportunities for procedural learning s and improvement re-establish equivalent land capability (where applicable) January 2017 Page 3

7 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project 2.2 Methodology Criteria for Success and Effectiveness of Construction Mitigation Measures Reclamation success and effectiveness of mitigation measures applied during construction are determined by comparing the construction ROW against the representative area adjacent to and off the construction ROW (control), and observing that the ROW is restored to a condition similar to the surrounding environment and consistent with the current land use. Where environmental issues are observed, corrective actions are planned and implemented in a timely manner and over subsequent reporting years until the environmental issue has been Ultimately, the criteria established for evaluating success and determining the effectiveness of mitigation practices used during pipeline construction is a reduction in the number of issues observed in subsequent monitoring years and maintaining a positive trajectory to re-establish equivalent land capability PCRM Methodology for Monitoring Preliminary Work Preliminary work includes a review of relevant project related information, including, but not limited to, alignment sheets and drawings, EPP, previous PCM reports, and previous assessments and recommendations Physical Environment Landscape Monitoring A landscape assessment of the construction ROW is performed to document evidence of the reclamation success. The landscape assessment consists of a visual evaluation of coarse fragments (stones, gravel, woody debris, etc.), contour restoration and drainage (maintaining natural drainage patterns), and microtopography (describing terrain instability, excessive crown height, subsidence, or erosion features) along the ROW. Where these issues are present and are a direct result of construction activities, the affected area is delineated along the length of the construction ROW Vegetation Monitoring Vegetation on the ROW is visually assessed for ground cover of desirable species by estimating the total percent of live cover compared to off ROW conditions. The occurrence and type of undesirable species (i.e., weeds) are assessed by estimating the percent cover using the same method. The pipeline ROW is inspected for other vegetation issues such as poor vegetation establishment. Vegetation parameters, based on land use and issue noted, assessed may include: bare soil exposure, visible erosion, surface litter, grazing pressure and plant vigour weed species and densities present January 2017 Page 4

8 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project Watercourse Monitoring The banks and approach slopes of the watercourse crossings are monitored for environmental issues which could potentially affect fish or alter fish habitat. Issues monitored include bank stability, morphology, invasive species, revegetation success, soil erosion and sedimentation, as well as the effectiveness of post construction erosion and sediment control measures and in-channel flow Wetland Monitoring The first year PCM Report identified that the wetlands were experiencing slow regeneration of vegetation and continued monitoring was recommended. The wetlands were expected to return to their pre-construction functional condition given additional growing seasons. This assertion was confirmed by the observation of substantial improvements in vegetation growth during the second and third growing season assessments. Continued wetland monitoring is guided by the Project s wetland monitoring plan. Wetland monitoring conducted by the PCRM Program focuses on the continued recovery through a visual assessment of substrate function, hydrologic function, water quality, vegetation cover and composition, wildlife habitat, and overall wetland function Wildlife and Wildlife Habitat Monitoring The construction ROW is monitored for the restoration of wildlife habitat by monitoring for vegetation re-establishment. Methods for vegetation monitoring are outlined above. 3.0 RESULTS AND RECOMMENDATIONS 3.1 First Year Post Construction Monitoring Summary (2012) The First Year PCM Program field work was completed by Tera Environmental Consultants (TERA) on September 14, 2012 (wetland specialists) and September 29-30, 2012 (reclamation specialists). The first year report was submitted to the NEB prior to January 31, Overall the report indicated that the Project achieved a high standard of environmental protection. Issues were varied, but focused on poor vegetation establishment, presence of weeds, and minor subsidence. 3.2 Second Year Post Construction Monitoring Summary (2013) PCRM completed a ROW assessment on May 27 28, The assessment was completed to examine unresolved environmental construction issues identified in the first year report, assess the effectiveness of mitigation efforts, identify and assess any January 2017 Page 5

9 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project new issues related to reclamation, and recommend reclamation measures to address outstanding environmental concerns. The primary issues noted during the assessments were minor subsidence, the presence of weeds, minor erosion, and reduced vegetation cover. Rare plant specialists completed a rare plant survey on the Project on August 8, Twelve rare plant sites were visited during the survey. Eleven of the sites were resolved by locating the rare plant in question on the ROW. One location was resolved, but the target species was not located, it was determined by the rare plant specialists during the site visit that the mitigation measures were successful because the habitat to support the rare plant was restored following construction. No further rare plant assessments are required for the Project. Details of these findings are present in Table 1 (). 3.3 Third Year Post Construction Monitoring Summary (2014) PCRM program completed a ROW assessment from June 11-20, The assessment was completed to follow-up on any unresolved environmental issues identified in the previous PCRM program assessments. In addition, the assessments are used to determine the effectiveness of mitigation efforts, identify new issues related to reclamation, and recommend measures to address outstanding environmental concerns. Overall the ROW recovery is on a trajectory to a regaining pre-disturbance condition. The vegetation was in excess of 90% cover (compared to adjacent land off ROW) on the majority of the ROW. Issues noted during the 2014 assessments were the presence of noxious weeds, minor subsidence, and erosion. 3.4 Fourth Year Post Construction Monitoring Summary (2015) PCRM completed the ROW assessment in the spring 2015 (May 31 June 5 and 9, 2015). The assessment was completed to examine unresolved environmental construction issues identified in the previous PCRM program assessments, assess the effectiveness of mitigation efforts, identify and assess any new issues related to reclamation, and recommend reclamation measures to address outstanding environmental concerns. Overall the ROW recovery is on a trajectory to a regaining pre-disturbance condition. The vegetation was in excess of 90-95% cover (compared to adjacent land off ROW) on the majority of the ROW. Issues noted during the 2015 assessments were the presence of noxious weeds, minor subsidence, and erosion. Construction of an adjacent NGTL pipeline was completed over the winter of , where the new pipeline ROW encroaches upon the existing Project ROW (affecting approximately half of the width of the ROW over the majority of the length from January 2017 Page 6

10 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project KP to ). The newly disturbed portions of the Project s ROW will be monitored as a part of the new pipeline s PCM program. 3.5 Fifth Year Post Construction Monitoring Summary (2016) PCRM Consultation NGTL continues to work closely with stakeholders to identify and address any concerns regarding the Project. A summary of NGTL s engagement efforts can be found in Appendix D PCRM Assessment and Reclamation Work PCRM completed the initial ROW assessment in June The assessment was completed to examine unresolved environmental construction issues identified in the previous PCRM program assessments, assess the effectiveness of mitigation efforts, identify and assess any new issues related to reclamation, and recommend reclamation measures to address outstanding environmental concerns. Additional assessments and remediation work were completed on the ROW in July, August, and September Construction of an adjacent NGTL pipeline was completed over the winter of , where the new pipeline ROW encroaches upon the existing Project ROW (affecting approximately half of the width of the ROW over the majority of the length from KP to ; Photo 1, Appendix C). Final cleanup of the new pipeline is scheduled to take place over the winter. These recently disturbed portions of the ROW were not assessed and no remediation activities took place during the Project s 2016 PCRM program. The newly disturbed portions of the Project s ROW will be monitored as a part of the new pipeline s PCM program. Details of the ROW assessments, findings and work completed are provided in Table 1 (). All issues on the Project related to vegetation cover and composition, erosion, subsidence, ponding, drainage, and a substantial proportion of weed issues are resolved following the completion of the fifth year of the PCRM program (Photos 2 to 6, Appendix C provide an overview of the typical conditions present on the ROW). The two wetlands (KP to 4+150, Photo 7, Appendix C and KP to , Photo 8, Appendix C; assessed in accordance with the Project s Wetlands Post-Construction Monitoring Plan) were found to be functional and no further monitoring was recommended. Noxious weeds are the only remaining issue noted on the ROW. Noxious weeds are present on the Project s ROW following the fifth growing season. The weeds remaining on the ROW are primarily perennial sow thistle, Canada thistle, tall buttercup, and meadow hawkweed. Substantial progress has been achieved in the elimination of noxious weeds over areas of the ROW and great reductions in the January 2017 Page 7

11 Cutbank River Lateral Loop (Bald Mountain Section) Pipeline Project extent of the weeds (details provided in Table 1, ). In locations where noxious weeds are remaining, the Project ROW is located adjacent to parallel and perpendicular disturbances. Weed control within these disturbances is outside the control of the Project s PCRM program. The presence of these disturbances makes the complete elimination of noxious weeds on the Project ROW unlikely. As a result, there are no further plans to monitor or control weeds through this Project s PCRM program PCRM Planned Activities The Project will be transferred to the applicable TransCanada Regional Operations and the PCRM Program will have no further involvement on this Project. 4.0 CONCLUSION The results of the NGTL PCRM assessments indicate that a high level of environmental protection has been maintained throughout the Project. There is no further work by NGTL s PCRM program planned for the Project is the fifth growing season and this report is the final scheduled postconstruction environmental monitoring report for submission to the NEB, as described in the approval for the Project (XG-N (NEB 2010)). 4.1 Project Team Contacts The Project Team is comprised of company representatives who had a role performing work on the Project and may be contacted should issues or concerns arise.
