1.0 INTRODUCTION NOVA Gas Transmission Ltd. (NGTL), a wholly owned subsidiary of TransCanada PipeLines Limited, has applied to the National Energy Board (NEB) under Section 52 of the NEB Act for authorization to construct and operate the Northwest Mainline Expansion (the Project). The Project includes construction of three separate pipeline loops referred to as the Horn River Mainline (Kyklo Creek Section), Northwest Mainline (Timberwolf Section) and the Tanghe Creek Lateral Loop No. 2 (Cranberry Section) (Figure 1). The Project was approved by the NEB on February 28, 2012. Construction is scheduled to commence during the fall of 2012 with a scheduled in-service date of April 2013. As part of the Project, NGTL is proposing the following (all Figures are provided in Appendix A):

• Kyklo Creek Section: 1 water source for hydrostatic testing and associated proposed and alternative hydrostatic test access routes and 3 borrow pits (Figure 2); • Timberwolf Section: 3 proposed and 8 potential water sources for hydrostatic testing and associated hydrostatic test access routes (Figure 3); and • Cranberry Section: 2 proposed water sources for hydrostatic testing and associated hydrostatic test access routes (Figure 4).

TERA Environmental Consultants (TERA) conducted a site visit to review the hydrostatic test sites, hydrostatic test access routes and borrow pits to identify any constraints from a wildlife habitat perspective on June 18 and 19, 2012 (Kyklo Section), August 4 and 5, 2012 (Timberwolf Section) and August 6, 2012 (Cranberry Section). The objective of the wildlife field work was to ensure important wildlife habitat features would not be affected and to recommend additional general or site-specific mitigative measures, where warranted, to avoid or minimize potential effects on wildlife (particularly species of concern) and important site-specific habitats.

In alignment with the objectives of the TEK study program for the Project, shared traditional knowledge was documented during all biophysical studies conducted for the Project, to provide input to the design and execution of biophysical and socio-economic discipline programs. A TEK study was conducted for this wildlife review in collaboration with representatives from Beaver First Nation, Dene Tha’ First Nation, Doig River First Nation, Duncan's First Nation, Fort Nelson First Nation, Fort Vermilion Métis Local 74, Paddle Prairie Métis Settlement, Prophet River First Nation and TERA.

Known reference points along the route are commonly referred to as KPs. As a result of the Project involving the construction of three separate pipeline loops, the following KP designators have been established to distinguish each pipeline loop:

• Kyklo Creek Section: Kilometre Post Kyklo (KPK) starting at a point adjacent to the existing Sierra Gas Plant at b-25-K/94-I-11 (KPK 0) to a tie-in point at a-97-F/94-I-10 (KPK 29.1);

• Timberwolf Section: Kilometre Post Timberwolf (KPT) starting at the proposed NGTL Moody Creek Compressor Station located at NW 3-109-12 W6M (KPT 0) to a tie-in point at NW 6-104-12 W6M (KPT 49.8); and

• Cranberry Section: Kilometre Post Cranberry (KPC) starting at a tie-in point at SW 31-96-7 W6M (KPC 32.3) to a tie-in point at NE 13-96-5 W6M (KPC 0).

2.0 METHODS 2.1 Field Data Collection An aerial overflight of the potential water sources for hydrostatic testing, hydrostatic test access routes and borrow pits was conducted to review the broader landscape and forest cover, the level and extent of human disturbance in the area, and to identify and investigate potential areas of wildlife importance (i.e., mineral licks, waterbodies, obvious stick nests, well-used travel corridors, etc.). Ground stops were conducted at selected locations based on the results of the aerial overflight and were accessed via helicopter and truck. All wildlife observations, evidence of wildlife use and important wildlife habitat features were recorded (i.e., field-data sheets, UTMs taken with a hand-held GPS and photographs for record-keeping). Selected Photoplates from the wildlife field work are provided in Appendix B.

2.2 Traditional Ecological Knowledge Traditional Ecological Knowledge (TEK) holders from participating communities and a TERA TEK facilitator participated in the wildlife field work (Table 1). An open dialogue was conducted with the community TEK holders and shared traditional knowledge was documented. Participants identified wildlife, wildlife signs, important habitats and provided accounts of changes to wildlife resources over time. The TEK study was completed in collaboration with representatives from Beaver First Nation, Dene Tha’ First Nation, Doig River First Nation, Duncan's First Nation, Fort Nelson First Nation, Fort Vermilion Métis Local 74, Paddle Prairie Métis Settlement, Prophet River First Nation and TERA.

The TEK observations in this report related to wildlife were collected during the wildlife field work, as well as observations during other field surveys for wetlands and aquatics.

3.0 RESULTS - KYKLO CREEK SECTION 3.1 Borrow Pit Sites There are three proposed borrow pits located in c-25-K/94-I-11, approximately 250 m north the Kyklo Creek Section (see Figure 2). The proposed borrow pits are located directly adjacent to each other and are entirely within previously disturbed land (Plate 1, Appendix A). The borrow pits are located within a Wood Bison Management Zone that covers northeastern BC and extends into Alberta (Harper et al. 2000) but is not located within an identified wood bison range. The borrow pit sites are not located in or adjacent to any other provincially identified wildlife areas (BC Ministry of Environment [MOE] 2010, 2012a,b, Ducks Unlimited and Canadian Wildlife Service [CWS] 2005, Breault et al. 2007).

Site #1 contains two smaller existing borrow pits and has been previously cleared. The existing borrow pits contain some regenerating cattail along the edges. The borrow pit to the north (Site #2) has also been previously cleared. No new clearing is required at either of these sites or for access. The adjacent habitat is dominated by deciduous and mixedwood forest dominated by trembling aspen and white spruce. There is a high level of existing disturbance in the vicinity, including existing pipeline rights-of- way, access roads and facilities.

An American black bear was observed along an existing pipeline right-of-way to the north of Site #2. Evidence of moose (tracks, pellets) and gray wolf (scat) was observed at both borrow pits. A small beaver lodge is located between the two existing borrow pits in Site #1 and two American beavers were observed on the larger of the two existing borrow pits. A common muskrat was also observed at this site. A small beaver dam is located adjacent to the southeast corner of Site #1, near the proposed temporary access.

Several waterfowl and shorebird species were observed on and adjacent to the existing borrow pits including: American wigeon, green-winged teal, killdeer, lesser yellowlegs, mallard, northern shoveler, solitary sandpiper and spotted sandpiper. Several songbird species were recorded in the adjacent deciduous and mixedwood forest (see Appendix C).

Amphibians were not observed on the borrow pits during the wildlife field work. A wood frog and several boreal chorus frogs were observed in habitats located adjacent to the borrow pits.

3.2 Hydrostatic Test Site and Access The potential water source for hydrostatic testing of the Kyklo Creek Section is located at an unnamed lake in b-41 and b-51-B/94-I-14 (HK-1) (Plate 2, Appendix B). There are two hydrostatic test access route options from the potential water source to the Kyklo Creek Section including a proposed access route which utilizes existing roads for the majority of its length and an alternate access route which utilizes primarily seismic/cutlines that will require clearing.

The unnamed lake and access are located within a Wood Bison Management Zone that covers northeastern BC and extends into Alberta (Harper et al. 2000) but is not located within an identified wood bison range. The unnamed lake and access are not located in or adjacent to any other provincially identified wildlife areas (BC Ministry of Environment [MOE] 2010, 2012a,b, Ducks Unlimited and Canadian Wildlife Service [CWS] 2005, Breault et al. 2007).

Evidence of moose (tracks, pellets), gray wolf (tracks, scat) and American black bear (tracks, scat) were recorded along both the proposed and alternate hydrostatic test access routes during the wildlife field work. Several black bears were observed in the vicinity during the aerial overflight. Red squirrels and their middens were also observed.

Several songbird species were observed during the wildlife field work, including Cape May warbler (provincially Red-listed in BC) and Le Conte’s sparrow (provincially Blue-listed in BC).

Two amphibian species, boreal chorus frog and wood frog were observed in the general area, however, there was no evidence of amphibian breeding sites (i.e., presence of egg masses, tadpoles) in any of the areas surveyed during ground stops.

3.3 Traditional Ecological Knowledge During the field study, participants reported that hunting and trapping occurs within the previously identified wildlife and wildlife habitat Regional Study Area (RSA). Table 2.4-1 describes the findings found by the field study participants including animal tracks, game trails and beaver lodges.

Moose tracks were observed along the proposed a-25-K/94-I-11 borrow pit access route (proposed hydrostatic test access route option to hydrostatic source lake), approximately 230 m north of KPK 0. A beaver lodge was identified along a watercourse crossed by the western access option approximately 200 m north of KPK 0.

Moose sign was also identified along the alternative hydrostatic test access route option to the unnamed lake at 41, 42, 51 and 52-B/94-I-14, approximately 4.7 km north and 10.9 km north of KPK 11. Participants noted that abundant food sources and proximity to water on the alternative hydrostatic test access route option provide ideal habitat for moose, while the black spruce and aspen forest surrounding the lake itself provides moose with protection from predators. Evidence of bear climbing was noted on poplar trees at 821 m northeast and 4.4 km north of KPK 11 along the alternative hydrostatic test access route option. Poplar buds and high bush cranberry identified in the area are food sources for bears.

The unnamed hydrostatic source lake at 41, 42, 51 and 52-B/94-I-14, has evidence of beaver activity and a loon was sighted on the lake during a field study. Evidence of moose activity, indicated by a moose shed antler was found at the southern end of the lake amidst abundant food sources like grass and willow.

Participants indicated general concerns about the potential for water to become contaminated during construction, which also potentially impacts the health of wildlife that depends on these water sources. The field crew discussed the winter construction methods utilized for installation of the vehicle crossings on watercourses to reduce potential Project-related effects on water quality. After the discussion participants indicated they were satisfied with the proposed vehicle crossing methods.

Participants had no concerns that were not addressed by routine mitigation measures discussed and agreed upon during the supplemental field study for the Kyklo Creek Section related to wildlife resources or habitat.

4.0 RESULTS - TIMBERWOLF SECTION 4.1 Hydrostatic Test Sites and Access For the Timberwolf Section, the proposed sources of hydrostatic test water will be the Hay River in SW 22-108-12 W6M (Plate 3, Appendix A) and 2 waterbodies, as well as other potential sources (Plate 4, Appendix A). These are summarized in Table 2.

4.2 Traditional Ecological Knowledge Muskeg was noted within the study area and was identified by Aboriginal participants as providing ideal habitat and abundant food sources such as willow and grass for moose. During the field studies moose were observed near an existing access route approximately 8 km east of KPT 25, as well as near two unnamed proposed hydrostatic test lakes. These unnamed lakes are located at SE 5-106-12 W6M and at SW 33-106-11 W6M. Participants also reported that moose are hunted and lynx are trapped along the northwest portion of the Chinchaga Forestry Road, approximately 50 km south of KPT 49.8, outside of the Project area.

Game trails were noted by participants at two other proposed hydrostatic test lakes, located at NE 6-104- 12 W6M and at SW 8-104-12 W6M. A large active game trail paralleling the Hay River was also identified approximately 100 m west of KPT 5.5. Aboriginal participants identified caribou tracks approximately 2.4 km east of KPT 31.3 and 9.2 km east of KPT 22.8 during helicopter reconnaissance of the hydrostatic test sources and noted that caribou primarily eat lichen, willow and grass. Wolf tracks were noted approximately 4.7 km east of KPT 22 along an existing seismic line, which is a proposed access route for the Project. Participants explained that wolves can travel up to 100 km per day and will hunt moose, elk, deer and bison. Rabbit trails were identified near Chasm Creek which is crossed by a proposed hydrostatic test access route approximately 500 m east of KPT 30 and along another proposed hydrostatic test access route, approximately 4.7 km east of KPT 22.

Beaver dams were noted at three proposed hydrostatic test lakes located at NW 36-106-12 W6M, at NE 25-106-12 W6M and at NE 6-104-12 W6M. It was explained to all participants that should those lakes be used as a source of water for the hydrostatic testing, and then a local trapper would be hired to remove the beaver from the area in the late fall/early winter prior to the withdrawal of the water. Participants were satisfied with the mitigation for beaver at these locations.

During wetlands field work on July 26, 2012, participants observed swans at two proposed hydrostatic test lakes, located at SW 33-106-11 W6M and at SE 5-106-12 W6M, and waterfowl were also identified at the unnamed lake at NE 5-106-12 W6M. There were no concerns associated with these sightings, as participants explained the waterfowl would have move to another location during construction.

The field crews discussed how gaps will be located at major, active game trails encountered by the Project in order to maintain wildlife access during Project construction. Participants were please with this mitigation measure, however, no such trails were identified during the supplemental studies.

It was recommended by participants that the roaches created from backfilling are well-maintained following Project construction and that fences are installed at pipeline risers so that wildlife would not be impacted. Backfilling, clean-up and reclamation, and post-construction monitoring mitigation were discussed and it was explained that while no risers are planned for the Timberwolf section, as per Section 2.5.2 of the ESA for the Project, all facilities may be fenced or gravelled depending on ground conditions and the use of the site. Participants were satisfied with the standard measures discussed.

Participants had no concerns that were not addressed by routine mitigation measures discussed and agreed upon during the supplemental field study for the Timberwolf Section related to wildlife resources or habitat.

5.0 CRANBERRY SECTION - RESULTS 5.1 Hydrostatic Test Sites and Access For the Cranberry Section, the proposed sources of hydrostatic test water will be the Chinchaga River in NE 36-96-8 W6M (HC-1), approximately 1.5 km west of the Cranberry Section (Plate 5, Appendix A) (see Figure 4) and an unnamed lake with proposed access in NE and SW 29-96-9 W6M (HC-2) (Plate 6, Appendix A). Both water sources are located within the Chinchaga Caribou range and a secondary grizzly bear zone (AESRD 2010-2012). The potential water sources and access are not within any other provincially identified wildlife areas (AESRD 2010-2012).

Evidence of moose (tracks), deer (tracks) and American beaver (feeding activity, tracks) were recorded at the Chinchaga River hydrostatic test site during the wildlife field work. Two white-tailed deer were observed on the north shore of the Chinchaga River.

Common songbird species observed during the wildlife field work included black-capped chickadee and Lincoln’s sparrow. A red-tailed hawk was observed along the hydrostatic test access route to the Chinchaga River. A trumpeter swan, black terns and numerous unidentified waterfowl with young were observed at the unnamed lake in NE and SW 29-96-9 W6M. Two amphibian species, boreal chorus frog and wood frog were observed along the proposed hydrostatic test access route to the Chinchaga River during the wildlife field work.

5.2 Traditional Ecological Knowledge Participants noted that the wildlife and wildlife habitat RSA along the Cranberry Section supports commonly hunted animals including moose, caribou, deer, bear, wolf, waterfowl and beaver.

Moose, deer, wolf and beaver tracks were identified on the shore of the Chinchaga River, at a proposed withdrawal site at NE 36-96-8 W6M. Moose and deer frequent the Chinchaga River to water and feed on the vegetation at its banks. Subsequently, both wolves and hunters are drawn in to hunt these animals as they feed in the area. As much of the area in the wildlife RSA is low lying muskeg or wetland, participants noted that wildlife will generally preferentially choose routes based on the ease of travel on firm, high ground rather than wet areas. Moose are an exception; they are commonly found wading in wetlands feeding off of aquatic plants and in muskeg areas.

Evidence of caribou, bear and a trumpeter swan were observed at a proposed hydrostatic test lake at SW-29-96-9 W6M. Participants suggested that the low-lying, marshy area surrounding this unnamed lake would not be preferred terrain for bear den sites as bears require dry, sheltered areas on high ground like high river banks or terraces that are not subject to frequent flooding.

In recent years, participants have observed that moose populations have been declining in both the greater Chinchaga Forestry Road region as well as the Cranberry section area. In their opinion, this decline in moose in the area has been attributed to increased industrial development. Participants noted the importance of reclamation as moose will avoid cleared areas such as camps and rights-of-way until the vegetation has regenerated. The increasing frequency of bear sightings in the region are being attributed to bear’s attraction to the food and garbage associated with construction camps.

Although some sign of caribou activity was observed in the area, participants prefer to travel to lands near the northern border of Alberta in the winter months to hunt caribou, approximately 280 km north of the Cranberry Section. Participants brought forward general concerns about potential long-term adverse effects that development can have on sensitive caribou populations and migration patterns. In general, participants acknowledge the application of construction mitigation measures to reduce potential development project-related effects on wildlife. However, participants remain concerned about the long- term cumulative impacts of industrial development in caribou habitat on overall caribou health, populations and migration. As part of the Project, NGTL has provided a Caribou Habitat Restoration Plan (CHRP); an Offset Measures Plan; and a Caribou Habitat Restoration and Offset Measures Monitoring Plan to address cumulative impacts on caribou habitat.

6.0 RECOMMENDED MITIGATION Overall project planning in combination with the season of construction and the proposed mitigation measures will reduce potential environmental effects on wildlife and wildlife habitat.

6.1 Traditional Ecological Knowledge Participants did not recommend any additional site-specific mitigation strategies related wildlife resources or habitat.

6.2 Mitigation Measures Based on the results of the June 18 to 19 and August 4 to 6, 2012 field work, the following mitigation is recommended.

Kyklo Creek Section: • Use the proposed hydrostatic test access route to limit the amount of additional clearing required.

• Obtain the relevant permits for beaver dam removal at the borrow pits from the appropriate provincial regulatory agency. Comply with the Fisheries and Oceans Canada (DFO) Operational Statement for Beaver Dam Removal, where applicable, as well as any Project approval conditions (refer to the Project specific Environmental Protection Plan for more information).

• No other wildlife habitat features were identified during the 2012 field work that require site-specific mitigation.

Timberwolf Section / Cranberry Section: • No wildlife habitat features were identified during the 2012 field work that require site-specific mitigation.

• Although trumpeter swans were observed, no nests or cygnets were observed and the waterbodies have not been previously identified as provincially identified trumpeter swan waterbodies (AESRD 2010-2012). No mitigation is necessary since work at these waterbodies is scheduled during winter.

In general, the work is scheduled for frozen conditions and will avoid important periods for migratory birds and amphibians. In the event that a species with special conservation status and/or wildlife habitat feature is observed during the work, the appropriate regulatory agency should be contacted to determine if additional mitigation measures are warranted. Additional mitigation is listed in the Project Application and wildlife-specific reporting (TERA 2011a-d).

Based on the results of the wildlife review and discussions with TEK participants, no changes to mitigation in the Environmental Protection Plan are required.
