4.1.2 Open Water Aquatic Habitat Results

The results of the open water aquatic assessments conducted on the watercourses and other fish-bearing waterbodies crossed by the replacement pipeline route are summarized in Table 12.

The CCME (2007) guideline for the protection of aquatic life for pH ranges from 6.5 to 9.0. The CCME (2007) guideline for dissolved oxygen for coldwater species (e.g., salmonids) is 9.5 mg/L in early life stages and 6.5 mg/L in other life stages, while for coolwater species (e.g., esocids, percids) and warmwater species such as centrarchids, the guideline is 6.0 mg/L in early life stages and 5.5 mg/L in other life stages (CCME 2007). However, some species (e.g., several cyprinid species and brook stickleback) found in northern climates can tolerate and survive even lower dissolved oxygen levels (Barton and Taylor 1996). The following subsections include a discussion on these water quality parameters with a comparison to the CCME guidelines. 4.1.2.1 Alberta

Ribstone Creek at SKP 223.0 (AB-WC13) and Eyehill Creek at SKP 282.1 (AB-WC16) both had water present at the time of assessment in May 2014. Ribstone Creek did not have defined bed and banks present and had a mean wetted width of 49.6 m. Eyehill Creek had a mean bankfull width of 40.4 m.

Both Ribstone Creek at SKP 223.0 (AB-WC13) and Eyehill Creek at SKP 282.1 (AB-WC16) had a pH level of 7.1 which was within the CCME range for aquatic life (i.e., 6.5 to 9.0).

The dissolved oxygen level at Ribstone Creek at SKP 223.0 (AB-WC13) was above the guideline for coldwater species in all life stages other than early life stages (i.e., 6.5-9.5 mg/L). The dissolved oxygen level was above the guideline for coldwater species in all life stages (i.e., greater than 9.5 mg/L) at Eyehill Creek at SKP 282.1 (AB-WC16). Both crossing locations were noted to have aquatic vegetation present at the time of assessment. Eyehill Creek was also noted to have wave action due to high winds at the time of assessment. These conditions may have affected the dissolved oxygen levels by oxygen production from plant life and aeration from the wind. It is expected that dissolved oxygen levels often drop below the CCME minimum guideline for coolwater fish at both crossings at various times of the year. 4.1.2.2 Saskatchewan

Of the 30 watercourses, fish-bearing drainages and lake proposed crossings where land access was obtained, two were dry within the study reach at the time of assessment (i.e., Montgomery and Stony creeks at SKP 890.8 and SKP 963.0 [SK-WC78 and 89], respectively). An additional six proposed crossings at SKP 413.5, SKP 520.6, SKP 757.1, SKP 847.8, SKP 888.0 and SKP 892.3 were almost dry with the exception of isolated ponded sections (SK-WC14, 29, 64, 74, 77 and 79). Previous field investigations by AAR in May 2007 indicated that more water is present in the spring at those proposed crossing locations than when visited in September 2013 (AAR 2007a).

The remaining 22 proposed crossings visited all had water present at the time of assessment. Mean bankfull widths were less than 5.0 m wide within the study reach at 10 of the 21 proposed watercourse crossings visited at SKP 294.0, SKP 378.7, SKP 520.6, SKP 599.7, SKP 696.7, SKP 838.3, SKP 890.8, SKP 892.3, SKP 895.8 and SKP 963.0 (SK-WC1, 8, 29, 44, 52, 72, 78, 79, 80 and 89) where defined bed and banks were present. The remaining proposed watercourse crossings all had bankfull widths greater than 5 m, but less than 50.0 m. An exception was the proposed South Saskatchewan River crossing at SKP 518.2 (SK-WC28) which had a mean bankfull width of 641 m.

Of the 28 proposed watercourse, fish-bearing drainage and lake crossings that were visited where enough water was present to measure pH levels, 25 had pH levels within the CCME range for aquatic life (i.e., 6.5 to 9.0). The remaining proposed crossings at SKP 479.7, SKP 800.1, SKP 847.8 and SKP 892.3 (SK-WC 26, 68, 74 and 79) which included MacDonald Creek and Chapleau Lakes had pH levels above the CCME range, but less than 9.5.

Of the 28 proposed crossings visited where enough water was present to measure dissolved oxygen levels, seven proposed crossings at SKP 609.5, SKP 757.1, SKP 800.1, SKP 802.2, SKP 810.1, SKP 847.8 and SKP 892.3 had dissolved oxygen levels below the CCME guidelines for coldwater and coolwater species for all life stages (i.e., below 5.5 mg/L) (SK-WC46, 64, 68, 69, 70, 74 and 79). These

Page 45 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

proposed crossings with dissolved oxygen levels less than 5.5 mg/L included Manybone Creek and Chapleau Lakes. A notable proposed crossing of an unnamed drainage at SKP 847.8 (SK-WC74) had a dissolved oxygen level of 0.6 mg/L. At this proposed unnamed drainage crossing, the pearl dace and brook stickleback present in a shallow, isolated pond showed signs of distress and were jumping out of the water.

Dissolved oxygen levels were below the CCME guideline for early life stages but were above the CCME guidelines for coldwater species in other life stages, (i.e., 6.5-9.5 mg/L) at nine proposed crossings at SKP 294.0, SKP 479.7, SKP 511.4, SKP 520.6, SKP 696.7, SKP 700.3, SKP 838.3, SKP 895.8 and SKP 927.2 (SK-WC1, 26, 27, 29, 52, 53, 72, 80 and 87), including MacDonald, Cottonwood, Vipond and Little Pipestone creeks. Dissolved oxygen levels were above the CCME guideline for coolwater and coldwater species in all life stages (i.e., above 9.5 mg/L) at 11 proposed crossing locations at SKP 376.8, SKP 378.7, SKP 405.6, SKP 413.5, SKP 438.1, SKP 518.2, SKP 527.8, SKP 599.7, SKP 670.2, SKP 680.2, SKP 745.6 (SK-WC7, 8, 13, 14, 22, 28, 39, 44, 48, 50, 62). These proposed crossing locations included both Eagle Creek crossings, the South Saskatchewan River, Iskwao Creek, High Hill Creek and the Qu’Appelle River. It is likely that instream vegetation and algae influenced dissolved oxygen levels, particularly at proposed crossings with little to no flow present. High water levels and cooler temperatures during May 2014 also likely influenced dissolved oxygen levels at crossing locations that were assessed during this time.

The open water aquatic habitat results at select proposed watercourse crossing locations (key watercourse crossings and/or sensitive fish habitat) within Saskatchewan are discussed in more detail below:

Eagle Creek The proposed crossings of Eagle Creek at SKP 405.6 (upstream) and SKP 438.1 (downstream) (SK- WC13 and 22 respectively) were visited in May 2014 and had mean bankfull widths of 14.2 m and 10.0 m, respectively. The mean depth at the upstream crossing was 0.64 m and at the further downstream crossing it was 0.49 m. The study reaches at both crossings were characterized by homogenous habitat made up of predominantly run habitat with organics or fines for substrate. Cattle influences along the banks were evident at the upstream crossing.

South Saskatchewan River The South Saskatchewan River at SKP 518.2 (SK-WC28), which was visited in May 2014, had a mean bankfull width of 661.0 m and a mean depth of 1.38 m. Depths were highly variable and dependent on flow regulation by the upstream Gardiner Dam. Although side channels and islands were present within the study reach, the habitat was composed of uniform sand bottom runs. Cover was lacking, except for depth. Few areas of gravel and cobble substrate or riffles were noted. The banks were noted to be highly erodible and unstable.

More details on the study reach for the South Saskatchewan River crossing are available in the figure provided in Appendix A.

Iskwao Creek The proposed crossing of Iskwao Creek at SKP 599.7 (SK-WC44) was visited in May 2014 and was flooded at the time of assessment. The mean bankfull width was 2.5 m, however, the wetted width was 17.1 m due to the flooding. The mean depth was 0.54 m and was above the ordinary high water mark. The study reach was primarily flat habitat with some pools and riffles approximately 120 m downstream of the proposed centerline. The substrate was primarily composed of organics and fines, however, some gravel and cobble were present and may have been added during previous pipeline crossing construction.

Qu’Appelle River The proposed crossing of the Qu’Appelle River at SKP 670.2 (SK-WC48) had a mean bankfull width of 21.9 m and a mean depth of 2.51 m. The watercourse was flooded at the time of assessment and is likely influenced by the upstream Qu’Appelle River Dam and Buffalo Pound Dam. The study reach was

Page 46 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

composed of fines and organics and was entirely run habitat. The study reach lacked complexity, however, cover was abundant in the form of depth and high turbidity.

Wascana Creek (SK-WC59) Land access was not available for the proposed Wascana Creek crossing at SKP 738.8 (SK-WC59). An aquatic assessment for the Enbridge ACEP was conducted by AAR on Wascana Creek in June 2007 near the proposed replacement pipeline crossing at SKP 738.8 (SK-WC59) (AAR 2007a). The mean bankfull width was 12.8 m and the mean depth was 0.7 m. The study reach was composed of fine substrate and run habitat. Updated information will be collected during supplemental studies.

4.1.1.6 Manitoba Water was present at all of the proposed watercourse and fish-bearing drainage crossing locations at the time of assessment where land access was obtained. At the proposed fish-bearing drainage crossings at SKP 1236.1 (MBR-WC8) and SKP 1255.7 (Rosenheim Drain; MB-WC76), conditions were dry throughout the study reach, but had ponded sections of water downstream. Of the 14 proposed crossings visited, three had mean bankfull widths less than 5.0 m within the study reach. The proposed crossings with bankfull widths less than 5.0 m were Spring Brook at SKP 1100.4 (MB-WC36), Thornhill Coulee at SKP 1223.5 (MBR-WC3) and Hespeler Drain at SKP 1245.9 (MB-WC73). The bankfull widths at the remaining proposed crossings ranged from 7.0 m to over 50.0 m with the widest being the Souris River.

At all of the proposed watercourse and fish-bearing drainage crossings visited, pH levels were within the CCME range (i.e., 6.5 to 9.0).

Dissolved oxygen readings were below the CCME guideline (i.e., below 5.5 mg/L) at four of the 14 proposed crossings where land access was obtained (Black Creek at SKP 1087.6 [MB-WC27], Spring Brook at SKP 1100.4 [MB-WC36], Oak Creek at SKP 1133.0 [MB-WC44] and Hespeler Drain at SKP 1245.9 [MB-WC74]). The dissolved oxygen levels at these four proposed crossings ranged from 3.6-5.4 mg/L. Dissolved oxygen readings did not meet the guideline for early life stages, however, were above the CCME guideline for other life stages of cool water species (i.e., 5.5-6.0 mg/L) at Oak Creek at SKP 1132.0 (MB-WC43). Dissolved oxygen levels were below the CCME guideline for early life stages but were above the CCME guidelines for coldwater species in other life stages (i.e., 6.5-9.5 mg/L) at seven proposed crossings (MB-WC1, 32, 42 and MBR-WC3 and 8, MB-WC76 and 78) including Pipestone Creek at SKP 971.9 (MB-WC1), the Souris River at SKP 1095.3 (MB- WC32), Oak Creek at SKP 1109.5 (MB-WC42), Thornhill Coulee at SKP 1223.5 (MBR-WC3), Rosenheim Drain at SKP 1255.7 (MB-WC76) and Buffalo Creek at SKP 1262.9 (MB-WC78). The dissolved oxygen readings at the proposed Cypress River crossing at SKP 1143.5 (MB-WC48) and the unnamed tributary to Buffalo Creek at SKP 1267.2 (MB-WC79) exceeded the CCME guideline for all life stages of coldwater and coolwater species (i.e., greater than 9.5 mg/L).

The open water aquatic habitat results at select proposed watercourse crossings (key watercourse crossings and/or sensitive fish habitat) in Manitoba are discussed in more detail below:

Pipestone Creek The proposed crossing of Pipestone Creek at SKP 971.9 (MB-WC1) was visited in June 2014. The substrates predominantly consisted of fines, however some gravels, cobbles and boulders were present. The boulders were noted to be from the addition of rip-rap during previous pipeline crossings. The mean bankfull width was 23.2 m and the mean depth was 0.75 m. The right bank at the proposed crossing location was noted to be unstable. Cover was predominantly in the form of boulder and depth.

Souris River (MB-WC32) At the proposed crossing of the Souris River at SKP 1095.3 (MB-WC32), the mean bankfull width was 53.5 m and the mean depth was 1.99 m in June 2014. The study reach was characterized by run habitat. Flood signs were present and the most recent high water mark was 2.5 m above the ordinary high water mark indicating high flows in the spring. Cover was predominantly woody debris and depth. The substrate was variable and consisted of fines, gravels and cobbles. It was also noted that the banks were unstable throughout the study reach.

Page 47 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

Spring Brook (MB-WC36) The proposed crossing of Spring Brook at SKP 1100.4 (MB-WC36) was visited in September 2013. The mean bankfull width was 3 m and the mean depth was 0.23 m. A low water barrier was present at the proposed crossing and 100 m downstream which disrupted connectivity. A deep pool was present and began approximately 65 m downstream. The study reach had predominantly flat habitat and abundant instream vegetation. The substrate was composed of predominantly fines, however, small and large gravel was present.

Oak Creek (MB-WC42, 43 and 44) The downstream proposed crossing of Oak Creek at SKP 1109.5 (MB-WC42) was visited in June 2014. The substrate predominantly consisted of fines, however some gravels and boulders were present. The study reach was characterized by runs, flats and pools. The mean bankfull width was 11.0 m and the mean depth was 0.56 m. Cover types were variable and consisted of overhanging vegetation, woody debris, instream vegetation, undercut banks and depth.

The two furthest upstream proposed crossings of Oak Creek (MB-WC43 and 44) were visited in July 2013. Of these two proposed crossings, the crossing at SKP 1133.0 (MB-WC44) is located further upstream than the crossing at SKP 1132.0 (MB-WC43). The downstream proposed crossing (MB-WC43) had a mean bankfull width of 17.2 m and a mean depth of 1.35 m. The upstream proposed crossing (MB-WC44) had a mean bankfull width of 21.7 m and a mean depth of 1.01 m. The proposed replacement pipeline crossings on Oak Creek (MB-WC43 and 44) were within close proximity to each other (i.e., approximately 2.8 km stream length and 1.0 km straight distance). At the time of the assessments, both proposed crossings had similar conditions and were flooded due to recent heavy rains. A nearby landowner also indicated that the area regularly floods in the spring. Water from Oak Creek was noted to be flooded over the nearby existing culvert crossing. Instream vegetation and depth (i.e., water depths 1 m deep or greater) were the dominant forms of cover. No flow was detected at either of the Oak Creek proposed crossing locations and the water present was relatively stagnant likely due to a low gradient. Both of these Oak Creek proposed crossing locations were characterized by run habitat.

Cypress River (MB-WC48 and 49) Of the two proposed Cypress River crossings, the crossing at SKP 1156.2 (MB-WC49) is located further upstream than the crossing at SKP 1143.5 (MB-WC48). The proposed downstream Cypress River crossing (MB-WC48) was visited in September 2013. The mean bankfull width was 8.9 m and the mean depth was 0.12 m. Pools, riffles, runs and flats were present with instream vegetation being the dominant form of cover. Flood signs were present and the most recent high watermark was 2.0 m over the ordinary high water mark indicating high flows in the spring.

No land access was obtained for the further upstream proposed Cypress River crossing at SKP 1156.2 (MB-WC49). An aquatic assessment for the Enbridge SLP was conducted by AAR on Cypress River in October 2006 near the proposed replacement pipeline crossing at SKP 1156.2 (MB-WC49) (AAR 2007b). The mean bankfull width was 7.4 m and the mean depth was 0.3 m. The study reach was characterized by predominantly fine substrate and pool/riffle habitat. Updated information will be collected during supplemental studies.

Deadhorse Creek (MBR-WC5) Land access was not available for the proposed Deadhorse Creek crossing at SKP 1229.0 (MBR-WC5). Information will be collected during supplemental studies. Buffalo Creek (MB-WC78) The proposed crossing of Buffalo Creek at SKP 1262.9 (MB-WC78) was visited in October 2013. The mean bankfull width was 7.6 m and the mean depth was 1.04 m. The study reach was composed of deep, homogenous, flat habitat. Instream vegetation and overhanging grasses were present as cover. Riparian vegetation loss due to agricultural activities was evident. A man-made cobble riffle was also present downstream of the study reach. Otherwise the substrate was composed of organics and fines.

4.1.3 Fish Habitat Potential The fish habitat potential ratings for the watercourses, fish-bearing drainages/wetlands and lakes crossed by the replacement pipeline route are summarized in Table 13 for crossings where land access was obtained. Fish habitat potential ratings are discussed for northern pike, walleye, white sucker and brassy minnow/black bullhead.

4.1.3.1 Alberta Northern pike and brassy minnow spawning and rearing habitat potential was rated as Important at Ribstone Creek at SKP 223.0 (AB-WC13) because of abundant instream vegetation. Migration habitat potential was rated as Important for all species rated. Wintering and migration were rated as Important for all species rated at Eyehill Creek at SKP 282.1 (AB-WC16).

4.1.3.2 Saskatchewan The South Saskatchewan River at SKP 518.2 (SK-WC28) was rated as Unsuitable to Marginal for all species rated (i.e., lake sturgeon, northern pike, walleye, white sucker and brassy minnow) for spawning, rearing and wintering habitat potential due to a lack of cover, appropriate substrate, habitat complexity and water fluctuations due to dam regulation. However, migration habitat potential was rated as Important for all species rated.

Iskwao Creek at SKP 599.7 (SK-WC44) was rated as Important for spawning, rearing and migration habitat potential for northern pike, white sucker and brassy minnow. Of note, an adult male white sucker in spawning condition was captured indicating potential spawning habitat in the watercourse where coarse substrate is present. Migration habitat potential was also rated as Important for all species rated (i.e., northern pike, walleye, white sucker and brassy minnow), except for walleye which was rated as Marginal. Wintering habitat potential was rated as Marginal or Unsuitable for all species rated.

Abundant flooded vegetation and spring high water conditions provided Essential spawning, rearing and migration habitat potential for bigmouth buffalo at the Qu’Appelle River at SKP 670.2 (SK-WC48). Spawning habitat potential was rated as Important for both northern pike and brassy minnow. Rearing and migration habitat potential for northern pike, walleye, white sucker and brassy minnow was rated as Important. Wintering habitat potential was rated as Important for bigmouth buffalo, northern pike and brassy minnow, but not for walleye which was rated as Marginal.

Cottonwood Creek at SKP 696.7 (SK-WC52) was rated as Important for northern pike, white sucker and brassy minnow spawning habitat potential. Migration habitat potential was rated as Important for all species rated (i.e., northern pike, walleye, white sucker and brassy minnow), except walleye.

Spawning, rearing and wintering habitat potential were rated as Marginal or Unsuitable for all species rated (i.e., northern pike, walleye, white sucker and brassy minnow) at the majority of the remaining proposed watercourse, fish-bearing drainage and lake crossing locations in Saskatchewan. In some cases, white sucker and brassy minnow spawning, rearing or wintering were rated as Important and migration ratings for all species were also rated as Important where suitable depth and/or connectivity was present. Generally, a lack of appropriate habitat type, connectivity, depth, agricultural disturbance, low dissolved oxygen levels, and high conductivity readings contributed to these ratings. It is expected that these crossing locations would only provide habitat for small-bodied fish species or other species that are tolerant of relatively poor habitat conditions (e.g., white sucker, brook stickleback, fathead minnow, pearl dace). Seasonal habitat use by some sportfish (e.g., northern pike) may be possible during high flows at these proposed watercourse, fish-bearing drainage and lakes crossings.

4.1.3.3 Manitoba Pipestone Creek at SKP 971.9 (MB-WC1) was rated as Important walleye rearing habitat potential. White sucker was rated as Important for spawning and rearing habitat potential. All species rated (i.e., northern pike, walleye, white sucker and brassy minnow) were rated as Important for migration habitat potential.

Suitable cobble/gravel substrates and velocities provided Essential spawning and migration habitat potential for walleye at the proposed Souris River crossing location at SKP 1095.3 (MB-WC32). Rearing

habitat potential was rated as Important for walleye. Wintering habitat potential was rated as Important for northern pike, walleye and white sucker and Marginal for brassy minnow.

Northern pike and brassy minnow spawning and rearing habitat potential were rated as Important at the proposed Spring Brook crossing location at SKP 1100.4 (MB-WC36). Instream vegetation and other forms of cover were present. Juvenile northern pike were also captured indicating rearing and spawning habitat potential. An overwintering pool present within the study reach provided Important Wintering habitat potential for northern pike, white sucker and brassy minnow. Migration habitat potential was rated as Marginal for all species rated (i.e., northern pike, walleye, white sucker and brassy minnow).

Oak Creek at SKP 1109.5 (MB-WC42) was rated as Important for northern pike spawning and rearing habitat potential as suitable instream vegetation was present. White sucker habitat potential for spawning, rearing and wintering was rated as Important. All species rated (i.e., northern pike, walleye, white sucker and brassy minnow) were rated as Importation for migration habitat potential.

Spawning and rearing habitat potential were rated as Important for northern pike at both proposed Oak Creek crossing locations at SKP 1132.0 and SKP 1133.0 (the two furthest upstream crossings) (MB-WC43 and 44) where abundant instream vegetation was present. Juvenile northern pike were captured in Oak Creek indicating the presence of potential rearing and spawning habitat. Wintering habitat potential was rated as Marginal and migration habitat potential was rated as Important for all rated species (i.e., northern pike, walleye, white sucker and brassy minnow).

Spawning and rearing habitat potential was rated as Unsuitable or Marginal for northern pike and walleye at the downstream proposed Cypress River crossing location at SKP 1143.5 (MB-WC48). White sucker and brassy minnow spawning and rearing habitat potential were rated as Important. Migration habitat potential was rated as Important for all rated species (i.e., northern pike, walleye, white sucker and brassy minnow). Wintering habitat potential was rated as Unsuitable for northern pike and walleye, Marginal for white sucker and Important for brassy minnow.

Abundant instream and overhanging vegetation provided Important spawning and rearing habitat potential for northern pike and black bullhead at the proposed Buffalo Creek crossing location at SKP 1262.9 (MB-WC78). Migration and wintering habitat potential was rated as Important for all rated species (i.e., northern pike, walleye, white sucker and black bullhead).

Habitat potential for all categories for northern pike, walleye and white sucker was rated as Unsuitable or Marginal at the unnamed tributary to Buffalo Creek at SKP 1267.2 (MB-WC79). However, spawning, rearing and wintering habitat potential was rated as Important for black bullhead. Migration habitat potential was rated as Unsuitable or Marginal for all species rated (i.e., northern pike, walleye, white sucker and black bullhead).

Spawning, rearing and wintering habitat potential were rated as Marginal or Unsuitable for all species rated (i.e., northern pike, walleye, white sucker, brassy minnow/black bullhead) at the rest of the proposed watercourse and fish-bearing drainage crossings in Manitoba. Generally, a lack of appropriate habitat type, connectivity and depth contributed to these ratings. It is expected that these proposed crossing locations would only provide habitat for small-bodied fish species and other species that are tolerant of relatively poor habitat conditions (e.g., white sucker, brook stickleback and fathead minnow). Seasonal habitat use by some sportfish (e.g., northern pike) may be possible during high flows at these proposed watercourse and fish-bearing drainage crossing locations.

4.1.4 Fish Inventory Results The sampling efforts and results of the fish inventory at the watercourses and other fish-bearing waterbodies crossed by the replacement pipeline route are provided in Table 14. Previous fish documentation is also discussed below and summarized in Table 16.

4.1.4.1 Alberta No fish were captured by minnow trapping during May 2014 at Ribstone or Eyehill creeks at SKP 223.0 and SKP 282.1(AB-WC13 and 16), respectively.

Ribstone Creek has been documented to contain northern pike, white sucker, shorthead redhorse, fathead minnow, lake chub and brook stickleback (FWMIS 2014). However, northern pike, white sucker and shorthead redhorse have only been documented to occur over 90 km downstream of the proposed replacement pipeline crossing (AB-WC13) near the confluence with the Battle River (FWMIS 2014). In addition there are multiple weirs present in the lower stretches of Ribstone Creek that likely impede fish migration (EMA 1993, AAR 2007a).

Brook stickleback and fathead minnow were previously captured by AAR in May 2007 near the proposed Eyehill Creek replacement pipeline crossing location (AB-WC16) (AAR 2007a). Sampling was also conducted by RL&L in May 1998 and no fish were captured (RL&L 1998b). No other fish have been previously documented to occur in Eyehill Creek (RL&L 1998b, FWMIS 2014). A weir is present approximately 800 m downstream of the proposed crossing and may impede fish migration.

4.1.4.2 Saskatchewan Where land access was obtained, fish sampling was conducted in watercourses, fish-bearing drainages and lakes crossed by the replacement pipeline route, except where proposed crossing locations were dry and at the unnamed irrigation canals at SKP 511.4 and SKP 527.8 (SK-WC27 and 39) (Table 14).

Boat/float electrofishing, backpack electrofishing, minnow trapping and dip netting were the fish sampling methods used in Saskatchewan. The South Saskatchewan River and Qu’Appelle River were sampled by boat and float electrofishing, respectively. Backpack electrofishing occurred at 12 proposed crossing locations, minnow trapping occurred at four proposed crossing locations and dip netting occurred at one proposed crossing location. A combination of backpack electrofishing and minnow trapping occurred at seven proposed crossing locations and a combination of minnow trapping and dip netting occurred at one proposed crossing location. Fish were captured or observed at 20 out of 28 proposed watercourse, fish-bearing drainage and lake crossing locations where sampling was conducted.

The fish inventory and previous documentation of fish are discussed in more detail below for select proposed watercourse crossings (e.g., named watercourse crossings and/or sensitive fish habitat).

Eagle Creek

Fathead minnow and brook stickleback were captured at the upstream Eagle Creek crossing location at SKP 405.6 by minnow trapping, but no fish were captured by backpack electrofishing (SK-WC13). No fish were captured at the downstream Eagle Creek crossing at SKP 438.1 (SK-WC22), however, cyprinid species were observed. A dead white sucker (cause of death unknown) was also found at the site.

Brook stickleback and fathead minnow were captured in May 2007 near the upstream proposed Eagle Creek crossing location at SKP 405.6 (SK-WC 13) (AAR 2007a). Sampling was also conducted near this location in May 1998 and resulted in the capture of brook stickleback, lake chub and fathead minnow (RL&L 1998c). AAR and RL&L also sampled near the downstream proposed Eagle Creek crossing location at SKP 438.1 (SK-WC22) in May 2007 and 1998, respectively, and these sampling events resulted in the capture of brook stickleback, pearl dace, lake chub and fathead minnow (RL&L 1998c, AAR 2007a). All the previous sampling events near the proposed Eagle Creek crossing locations were conducted by float or backpack electrofishing and minnow trapping.

Page 58 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

Eagle Creek is also documented to contain northern pike, white sucker, fathead minnow, lake chub, pearl dace, longnose dace and brook stickleback over 30 km downstream of both proposed replacement pipeline crossings (Atton and Merkowsky 1983).

South Saskatchewan River

Lake whitefish, white sucker and longnose sucker were captured by boat electrofishing at the South Saskatchewan River at SKP 518.2 (SK-WC28). All fish were captured approximately 2.9 km downstream of the proposed center line. The suckers captured were noted to be forming a spawning congregation.

Previous field investigations occurred at the South Saskatchewan River in May 1998 and 2007 by boat electrofishing near the proposed replacement pipeline crossing location at SKP 518.2 (SK-WC28). AAR (2007a) captured lake whitefish, white sucker and trout-perch (AAR 2007a). RL&L (1998c) captured rainbow trout, lake whitefish, white sucker and longnose sucker (RL&L 1998c).

The South Saskatchewan River and Lake Diefenbaker have also been documented to contain lake sturgeon, lake whitefish, lake trout, rainbow trout, brown trout, goldeye, mooneye, northern pike, walleye, sauger, yellow perch, burbot, longnose sucker, white sucker, quillback, silver redhorse, shorthead redhorse, lake chub, flathead chub, fathead minnow, pearl dace, emerald shiner, river shiner, spottail shiner, trout-perch, brook stickleback, spoonhead sculpin and Iowa darter (Atton and Merkowsky 1983, WSA 2012, FWMIS 2014). The following fish species have been stocked in Lake Diefenbaker: rainbow trout (1987 to 2005); lake trout (1970 to 1975); and brown trout (1987). Rainbow trout had also escaped from a local aquaculture operation in 1994 and 2000 (WSA 2012). These trout species may incidentally occur in the South Saskatchewan River downstream of the Gardiner Dam if any populations still exist in Lake Diefenbaker.

Lake sturgeon have been documented in Lake Diefenbaker as well as in the South Saskatchewan River downstream of Saskatoon (Atton and Merkowsky 1983), however, no recent occurrences have been reported between the Gardiner Dam and Saskatoon which is the reach of river where the proposed replacement pipeline crossing is located (DFO 2010a).

Iskwao Creek An adult male white sucker in spawning condition was captured by backpack electrofishing at Iskwao Creek at SKP 599.7 (SK-WC44). Northern pike and fathead minnow were previously captured by AAR in May 2007 at Iskwao Creek near the proposed crossing (AAR 2007a).

Qu’Appelle River Walleye, northern pike, white sucker, bigmouth buffalo, common carp and emerald shiner were captured by float electrofishing in May 2014.

The Qu’Appelle River was sampled in May in 1998 and 2007 near the proposed replacement pipeline crossing at SKP 670.2 by float electrofishing (SK-WC48). Walleye, white sucker, longnose sucker, common carp, emerald shiner, fathead minnow, longnose dace and brook stickleback were captured during these sampling events (RL&L 1998c, AAR 2007a). Most of the white sucker captured in May 1998 were males in spawning condition (RL&L 1998c). Bigmouth buffalo have also been observed in the Qu’Appelle River approximately 3 km downstream from the proposed replacement pipeline crossing (Golder 1997).

The Qu’Appelle River is also known to contain northern pike, walleye, sauger, yellow perch, goldeye, mooneye, burbot, black bullhead, channel catfish, rock bass, white sucker, quillback, bigmouth buffalo, shorthead redhorse, chestnut lamprey, common carp, common shiner, emerald shiner, river shiner, blacknose shiner, spottail shiner, sand shiner, fathead minnow, flathead chub, creek chub, longnose dace, western blacknose dace, trout-perch, ninespine stickleback, brook stickleback, Iowa darter, Johnny darter and blackside darter (Atton and Merkowsky 1983, McCulloch and Franzin 1996). Bigmouth buffalo and spoonhead sculpin are known to be more common in the Qu’Appelle River lakes as compared to the Qu’Appelle River mainstem (McCulloch and Franzin 1996).

Wascana Creek Land access was not available for the proposed Wascana Creek crossing at SKP 738.8 (SK-WC59). During October 2013, northern pike and lake chub were captured by backpack electrofishing in Wascana Creek approximately 7.5 km upstream of the proposed crossing at SKP 738.8 (SK-WC59). The northern pike captured was a juvenile.

Float electrofishing occurred at Wascana Creek in May 1998 and 2007 at pipeline crossings approximately 40 km downstream of and near the proposed replacement pipeline crossing, respectively (RL&L 1998c, AAR 2007a). These sampling events resulted in the capture of white sucker and fathead minnow (RL&L 1998c, AAR 2007a). Wascana Creek is also known to contain introduced common carp (Atton and Merkowsky 1983).

Other Watercourses and Fish-Bearing Waterbodies Fish species captured at the remaining smaller watercourses, fish-bearing drainages and lakes in Saskatchewan were brook stickleback, fathead minnow, lake chub, pearl dace, white sucker, and Iowa darter. Generally, fish inventory results at the remaining crossing locations are similar to previous fish inventories.

Spottail shiner along with fathead minnow and Iowa darter were also previously captured by AAR in May 2007 at Montgomery Creek near the proposed crossing at SKP 890.8 (SK-WC78) (AAR 2007a).

4.1.4.3 Manitoba Where land access was obtained, fish sampling was conducted at proposed watercourses and fish-bearing drainages crossed by the replacement pipeline route. Fish were captured or observed at all of the proposed crossing locations sampled in Manitoba (Table 14).

The sampling methods used in Manitoba were float electrofishing, backpack electrofishing, minnow trapping, and seine netting. Backpack electrofishing, a combination of backpack electrofishing and minnow trapping, and a combination of minnow trapping and seine netting, were used at eight, two and two proposed crossing locations, respectively. A combination of backpack electrofishing, minnow trapping and seine netting was conducted at Pipestone Creek at SKP 971.9 (MB-WC1). A combination of backpack electrofishing, minnow trapping and dip netting was conducted at Oak Creek at SKP 1109.5 (MB-WC42). The Souris River at SKP 1095.3 (MB-WC32) was sampled by float electrofishing.

The fish inventory and previous documentation of fish captured are discussed in more detail at the following select proposed watercourse crossings (e.g., named watercourse crossings and/or sensitive fish habitat).

Pipestone Creek Fathead minnow were captured by backpack electrofishing at Pipestone Creek at SKP 971.9 (MB-WC1). No fish were captured in minnow traps or during seine netting. The float electrofishing unit was not used due to landowner concerns which limited the effectiveness of fish sampling by backpack electrofishing as water levels were high.

AAR conducted backpack and float electrofishing near the proposed pipeline replacement crossing on Pipestone Creek at SKP 971.9 (MB-WC1) in May 2007 and captured white sucker, creek chub and longnose dace (AAR 2007a). Walleye, yellow perch, northern pike, white sucker, pearl dace, fathead minnow, Iowa darter and brook stickleback also occur in Pipestone Creek and/or Moosomin Reservoir (McCutcheon, Janusz pers. comm., Milani 2013). In the spring during high flow, runs of northern pike, walleye and white sucker have been observed in Pipestone Creek just downstream of the Moosomin Dam in Saskatchewan (McCutcheon pers. comm.). It is suspected that these fish may come from Oak Lake in Manitoba (McCutcheon pers. comm.). This suggests fish may migrate upstream from Oak Lake.

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

Souris River Walleye, yellow perch, black bullhead and white sucker were captured by float electrofishing. It was noted that due to high flows at the time of sampling, float electrofishing was not as effective as it would have been during lower flows.

Previous fish sampling in October 2006 and June 2008 on the Souris River near the proposed replacement pipeline crossing resulted in the capture of walleye, northern pike, white sucker, shorthead redhorse, common shiner, longnose dace, western blacknose dace, sand shiner, bigmouth shiner, Johnny darter, blackside darter and trout-perch (AAR 2007b, 2008a). Fish sampling also occurred in May 1998 near the same location which resulted in the capture of white sucker and shorthead redhorse (RL&L 1998c). Float electrofishing was used for these sampling events.

McCulloch and Franzin (1996) (various studies) and Milani (2013) (sampling in August 2006) reported the following fish species in the Souris River at various locations: goldeye; northern pike; walleye; yellow perch; burbot; rock bass; central mudminnow; common carp; common shiner; pearl dace; golden shiner; river shiner; bigmouth shiner; blacknose shiner; blackchin shiner; spottail shiner; sand shiner; northern redbelly dace; fathead minnow; flathead chub; western blacknose dace; longnose dace; creek chub; white sucker; shorthead redhorse; black bullhead; brown bullhead; stonecat; tadpole madtom; trout-perch; brook stickleback; Iowa darter; Johnny darter; and blackside darter.

Spring Brook Northern pike and creek chub were captured by backpack electrofishing near the proposed Spring Brook crossing location at SKP 1100.4 (MB-WC36). All of the northern pike (i.e., greater than 20) noted in a pool downstream of the proposed replacement pipeline crossing were juveniles.

Northern pike, lake chub, creek chub, fathead minnow, pearl dace and brook stickleback have been previously captured near the proposed Spring Brook crossing location by backpack electrofishing in the spring (RL&L 1998c, AAR 2007b).

Oak Creek Northern pike, rock bass, chestnut lamprey, white sucker, common shiner, sand shiner, longnose dace, western blacknose dace, and fathead minnow were captured by backpack electrofishing and minnow trapping in Oak Creek at SKP 1109.5 (MB-WC42). The northern pike and rock bass captured were juveniles. Of note, the chestnut lamprey was an adult and, when captured, was attached to and feeding on a white sucker.

Northern pike, white sucker, Johnny darter, Iowa darter, pearl dace, western blacknose dace, emerald shiner, creek chub and brook stickleback were previously captured by AAR in October 2006 near the furthest downstream proposed Oak Creek crossing at SKP 1109.5 (MB-WC42) (AAR 2007b).

Due to close proximity and habitat homogeneity, fish sampling was conducted at one location between the two Oak Creek proposed crossings at SKP 1132.0 and SKP 1133.0 (MB-WC 43 and 44) in July 2013. Juvenile northern pike were captured by minnow traps and Johnny darter, white sucker and an unidentified cyprinid species were captured during seine netting. The presence of juvenile northern pike indicates adults may spawn somewhere in Oak Creek. It was also noted by a nearby landowner that northern pike have been captured in the past by angling near the proposed upstream Oak Creek crossing locations (MB-WC 43 and 44).

AAR previously captured white sucker, creek chub, Iowa darter and brook stickleback during their assessment near the proposed replacement pipeline crossing location on Oak Creek (MB-WC44) in October 2006 (AAR 2007b). RL&L previously captured white sucker at both proposed upstream Oak Creek crossings in May 1998 (MB-WC 43 and 44) (RL&L 1998c).

Previous sampling in Oak Creek occurred in June 2004 and May 2006 and resulted in the capture of the following species at various locations: northern pike; white sucker; creek chub; fathead minnow; bigmouth shiner; common shiner; longnose dace; brook stickleback; trout-perch; blackside darter and Johnny darter (Milani 2013). Also of note, an individual adult chestnut lamprey was captured in Oak Creek

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

approximately 12 km downstream of the proposed Oak Creek crossing at SKP 1116.5 (MB-WC42) and near the confluence with Spring Brook (Milani 2013).

Cypress River Backpack electrofishing at the downstream proposed crossing of the Cypress River at SKP 1143.5 (MB-WC48) in September 2013 resulted in the capture of silver redhorse, white sucker, western blacknose dace, longnose dace, pearl dace, brassy minnow, creek chub, sand shiner, common shiner and emerald shiner. The Cypress River supports a diverse fish community, as 10 fish species were captured.

An aquatic assessment was conducted at the Cypress River by RL&L in May 1998 near the proposed downstream replacement pipeline crossing (MB-WC48) (RL&L 1998c). White sucker, Johnny darter, central mudminnow, common shiner, sand shiner, creek chub, finescale dace, fathead minnow and longnose dace were captured (RL&L 1998c).

No land access was obtained for the upstream proposed Cypress River crossing at SKP 1156.2 (MB-WC49). AAR also conducted an aquatic assessment near the proposed upstream Cypress River replacement pipeline crossing in October 2006 and black bullhead, white sucker, Johnny darter, blackside darter, western blacknose dace, creek chub, emerald shiner and fathead minnow were captured (AAR 2007b).

McCulloch and Franzin (1996) (various studies) and Milani (2013) (sampling in May/June 2004 and May 2006) reported the following fish species in the Cypress River at various locations: northern pike; rock bass; stonecat; white sucker; silver redhorse; common shiner; river shiner; bigmouth shiner; sand shiner; fathead minnow; western blacknose dace; longnose dace; finescale dace, creek chub; brook stickleback; Johnny darter; blackside darter; river darter; and central mudminnow.

Deadhorse Creek Land access was not available for the proposed Deadhorse Creek crossing at SKP 1229.0 (MBR-WC5).

Previous fish sampling by backpack electrofishing and minnow trapping occurred in May 1998, October 2006 and June 2008 approximately 9 km upstream of the proposed replacement pipeline crossing location at SKP 1229.0 (MBR-WC5) (RL&L 1998c, AAR 2007b, 2008a). These sampling events resulted in the capture of walleye, pumpkinseed, white sucker, creek chub, fathead minnow and lake chub (RL&L 1998c, AAR 2007b, 2008a). Lake Minnewasta, located approximately 10 km upstream from the proposed replacement pipeline crossing on Deadhorse Creek, is also known to contain northern pike, walleye, black crappie, bluegill, pumpkinseed, smallmouth bass, largemouth bass, white sucker, creek chub, hornyhead chub, common carp, brook stickleback and ninespine stickleback (Tetra Tech 2013). Black crappie, bluegill, pumpkinseed, smallmouth bass and largemouth bass have been stocked or inadvertently introduced in Lake Minnewasta multiple times since the 1940s (Tetra Tech 2013).

Previous sampling in Deadhorse Creek at various locations occurred in May/June from 2003 to 2005 and resulted in the capture of northern pike, black crappie, fathead minnow, creek chub, western blacknose dace, white sucker, shorthead redhorse, brook stickleback and trout-perch (Milani 2013).

Buffalo Creek A juvenile black bullhead was captured by minnow trapping at the proposed Buffalo Creek pipeline replacement crossing location at SKP 1262.9 (MB-WC78). Previous sampling by backpack electrofishing at Buffalo Creek resulted in the capture of black bullhead and creek chub (AAR 2007b).

Northern pike, white sucker, sand shiner and fathead minnow were also previously captured in Buffalo Creek at various locations in June 2003 and August 2005 (Milani 2013).

Other Watercourses and Fish-Bearing Waterbodies Fish species captured at the remaining smaller watercourses and fish-bearing drainages were brook stickleback, fathead minnow and pearl dace. Generally, these fish inventory results at the remaining proposed crossings are similar to previous fish inventories near the proposed crossings. An exception is

Page 62 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

the capture of a juvenile black bullhead by minnow trapping at the unnamed tributary to Buffalo Creek at SKP 1267.2 (MB-WC79). Other previously documented fish species are described below.

White sucker, western blacknose dace, creek chub, fathead minnow, brook stickleback, Johnny darter and central mudminnow were also previously captured at the unnamed tributary to the Pembina River near the proposed crossing at SKP 1165.0 (MB-WC50) in June 2008 (AAR 2008a). In addition, black bullhead, white sucker and creek chub were previously captured in October 2006 near the proposed crossing of the unnamed tributary to Buffalo Creek at SKP 1267.2 (MB-WC79) (AAR 2007b).

Central mudminnow are also documented to occur in Thornhill Coulee (Milani 2013). Previous sampling in Black Creek at various locations in July 2003 resulted in the capture of white sucker, fathead minnow, creek chub, common shiner and brook stickleback (Milani 2013). Previous sampling also occurred in Mary Jane Creek in June/July 2004 at various locations and the following species were captured: white sucker, black bullhead, common shiner, creek chub, fathead minnow, longnose dace, western blacknose dace, bigmouth shiner, brassy minnow, brook stickleback and Johnny darter (Milani 2013). Of these sampling events, only fathead minnow were previously captured upstream of Mary Jane Reservoir in Mary Jane Creek where the proposed crossing is located at SKP 1189.5 (MB-WC58) (Milani 2013).

4.1.5 Freshwater Mussel Inventory Results Mussel sampling was conducted at six watercourse crossings in September 2013 and June 2014 (Table 15). Freshwater mussels or evidence of their presence, where land access was obtained, were found or known to occur at the following proposed pipeline crossing locations: Pipestone Creek; the Souris River; all three Oak Creek crossings; and the downstream Cypress River replacement pipeline crossing. No other evidence of freshwater mussels was present at any of the other watercourse or fish-bearing drainage crossings sampled where land access was obtained. No land access was obtained for the upstream Cypress River crossing at SKP 1156.2 (MB-WC49) or Deadhorse Creek at SKP 1229.0 (MB-R-WC5), however, it is expected that freshwater mussels are present in these watercourses near the proposed crossing (AAR 2008b, Watson et al. 1998). No mapleleaf mussels were found or have been documented at any of the watercourses sampled along the replacement pipeline route. In addition, known fish hosts of the mapleleaf mussel (i.e., channel catfish) were not captured or observed.

Water levels were too high to conduct any mussel sampling at the Qu’Appelle River at SKP 670.2 in May 2014 (SK-WC48). No mussels or mussel shells were observed. Previous sampling occurred at a single location in the Qu’Appelle River which resulted in the capture of black sandshell, fatmucket and plain pocketbook (Watson et al. 1998). This sampling event occurred over 300 km downstream of the proposed replacement pipeline crossing location and is near the confluence of the Qu’Appelle River with the Assiniboine River.

Mussel sampling downstream of the proposed pipeline crossing at Pipestone Creek resulted in the capture of two fatmucket mussels in June 2014. Mussel shells which were suspected to be from white heelsplitter, giant floater, fatmucket and cylindrical papershell were also found in Pipestone Creek. Previous sampling in Pipestone Creek at various locations resulted in the capture of white heelsplitter, cylindrical papershell, giant floater and fatmucket (Watson et al. 1998).

Water levels were too high to conduct any mussel sampling at the Souris River at SKP 1095.3 in June 2014 (SK-WC48). Previous sampling for the Enbridge SLP near the proposed crossing resulted in the capture of fatmucket and white heelsplitter (AAR 2008b). Numerous mussels were captured (i.e., over 100 individuals) of different sizes during this previous sampling indicating that the Souris River provides high quality mussel habitat at some locations (AAR 2008b). The Souris River is also documented to contain white heelsplitter, creek heelspitter, giant floater, fatmucket, wabash pigtoe, threeridge, cylindrical papershell, creeper, black sandshell and plain pocketbook (Watson et al. 1998). The dam and weir on the Souris River within the Town of Wawanesa, Manitoba may prevent channel catfish, which are known to be a host of mapleleaf mussel, from migrating upstream to the proposed replacement pipeline crossing (RL&L 1998a, AAR 2008b).

Small, 10-15 mm mussels (n=10) were captured in June 2014 during sampling at the downstream Oak Creek crossing location at SKP 1116.5 (MB-WC42). Although these mussels could not be identified to species, they were not mapleleaf mussels. Mussel shells suspected to be from cylindrical papershell were also found in Oak Creek. No freshwater mussels were observed during the two aquatic assessments at the upstream Oak Creek replacement pipeline crossing locations at SKP 1132.0 and SKP 1133.0 (MB-WC 43 and 44). Flooded conditions did not allow effective mussel observation or sampling during July 2013, however, freshwater mussel shells were noted during October 2006 at Oak Creek along the exposed creek bed (AAR 2007b). These mussel shells were not noted to be from mapleleaf mussels (AAR 2007b). Oak Creek is known to contain wabash pigtoe, white heelsplitter, cylindrical papershell, giant floater, fatmucket and plain pocketbook (Watson et al. 1998).

Fatmucket were captured or observed within the study area at the downstream Cypress River pipeline replacement crossing location at SKP 1143.5 (MB-WC48). Mussels were captured both upstream and downstream of the proposed replacement pipeline crossing location. A mussel was captured 25 m downstream of the proposed centre line and, therefore, mussels may be present within the construction right-of-way during construction. Land access was not obtained for the upstream proposed Cypress River crossing at SKP 1156.2 (MB-WC49). The Cypress River is also known to contain white heelsplitter, creek heelsplitter, giant floater, cylindrical papershell and fatmucket (Watson et al. 1998).

Land access was not available for the proposed Deadhorse Creek crossing at SKP 1229.0 (MBR-WC5). Previous sampling occurred in Deadhorse Creek in June 2008 approximately 9 km upstream of the proposed replacement pipeline crossing location which resulted in the capture of fatmucket (AAR 2008b).

See Section 10 for future study plans at these watercourses. n/a = not applicable; TBD = to be determined

4.2 Permanent Facilities There are no watercourses or other fish-bearing waterbodies expected within 30 m of any permanent facilities. Construction activities at facilities will primarily occur within the existing boundaries of facilities and terminals. Therefore, no aquatic fieldwork was conducted at any of the permanent facilities.

Page 69 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

4.3 Temporary Facilities and Workspace Most of the temporary facilities and workspace will be located adjacent to the replacement pipeline route, and, therefore, most of the results of the field data collected and described in Section 4.1 for the replacement pipeline route are applicable.

The proposed shoo-fly crossing of Pipestone Creek at SKP 971.9 (MB-WC1) is located approximately 80 m upstream of the proposed replacement pipeline crossing. Habitat conditions were similar to the proposed pipeline crossing at the proposed shoe-fly crossing of Pipestone Creek and there were no notable features observed during the aquatic assessment.

The proposed shoo-fly crossing for the unnamed tributary to Pipestone Creek at SKP 975.6 (MB-WC4) is located approximately 70 m downstream of the proposed replacement pipeline crossing. No land access was obtained for the proposed shoo-fly crossing of the unnamed tributary to Pipestone Creek at SKP 975.6 (MB-WC4). The unnamed tributary to Pipestone Creek at SKP 975.6 has also not been confirmed to have defined bed and banks or have fish habitat present. Shoo-fly crossings will generally be located adjacent to the replacement pipeline route and habitat conditions are expected to be similar. The proposed shoo-fly crossing on the unnamed tributary to Pipestone Creek at SKP 975.6 (MB-WC4) will be visited once land access is obtained prior to construction.

4.4 Decommissioning The specific locations where physical activities will occur along the existing Line 3 pipeline have not been finalized. Prior to the commencement of any physical works to decommission the existing pipeline, each location will be selected in the field and will follow the process for environmental review outlined in the EPP (Appendix 1 of this ESA).

5.0 DISCUSSION AND RECOMMENDATIONS 5.1 Pipeline Recommended pipeline, vehicle and equipment crossing methods for the watercourses and fish-bearing drainages, and lakes crossed by the replacement pipeline route are provided in the following subsections. Table 16 provides a summary of the recommendations.

Pending regulatory approval, construction activities are expected to commence in Q2 2016 and extend to Q4 2017 for the replacement pipeline. Replacement pipeline preconstruction activities (e.g., mobbing to site) are expected to occur in Q2 2016 with actual replacement pipeline construction beginning in Q3 2016.

The following recommendations are based on TERA's current understanding of how the Fisheries Act and other applicable acts are administered. Due to possible regulatory changes, a review of the recommendations should be conducted prior to construction to ensure compliance with policies at that time.

TERA has recently developed a decision making tool to evaluate proposed works against the DFO Self-Assessment for Projects Near Water (DFO 2014a). This process is used to determine if serious harm to fish will occur as a result of a proposed work, and whether review by DFO and/or an Authorization under the Fisheries Act is required. This process takes into account the sensitivity of the fish and fish habitat and the scale of the potential negative effect of the proposed works on the fish and fish habitat. The results of these evaluations for each proposed watercourse and other fish-bearing waterbody crossing where land access was obtained are provided in Appendix A.

5.1.1 General Aquatic Recommendations Mitigation measures to reduce potential environmental effects on fish, fish habitat and freshwater mussels during construction and operation of the Project are provided in the EPP (Appendix 1 of the ESA) and in Sections 6.2.3 and 6.2.7 of the ESA (TERA 2014). In general, it is recommended to avoid working in or near any watercourses and other fish-bearing waterbodies during periods of high flow in the spring and early summer or heavy precipitation.

For reference, previous pipeline and vehicle crossing methods used during the construction of the Enbridge ACEP and SLP are provided in Table 16.

5.1.2 Recommended Pipeline Crossing Methods It is anticipated that instream activities will not occur during any RAPs or restricted activity timing windows. If these plans change it will be necessary to discuss the changes with a qualified fish biologist to ensure appropriate mitigation measures to avoid serious harm to fish and fish habitat are implemented and confirm regulatory requirements are met.

The recommended pipeline crossing methods for the South Saskatchewan River (SK-WC28), the Qu’Appelle River (SK-WC48) and the Souris River (MB-WC32) are trenchless to reduce the potential to negatively affect the productive capacity of the aquatic environment at these crossings and to reduce the risk of serious harm to fish.

Trenchless crossing methods are also recommended at the unnamed irrigation canals at SKP 511.4 and SKP 527.8 (SK-WC27 and 39, and locally known as Macrorie Canal and Cutbank Canal, respectively). These canals are big, steep banked and lined with a fabric material. A trenchless method is likely the only feasible option that can be implemented while maintaining the integrity of the canal for its intended purpose. Additional irrigation canals or agricultural drains may be crossed using a trenchless crossing method depending on landowner considerations, water quality concerns for agricultural use, construction timing and engineering factors. Many of these canals/drains were previously successfully crossed using a trenchless crossing method (see Table 16) (TERA Environmental Consultants 2011a,b).

The recommended pipeline crossing method for the remaining watercourses and other fish-bearing crossings is a trenched pipeline method (Table 16). An isolated trenched method is recommended if

Page 71 Application Submitted to the NEB Appendix 6

Enbridge Pipelines Inc. Aquatic Technical Report Line 3 Replacement Program November 2014/10427

water is present at the time of construction, while an open cut method is recommended if the waterbody is dry or frozen to the bottom at the time of construction.

The recommended pipeline crossing methods for all watercourses and other fish-bearing waterbodies are included under the Dewatering/Pumping activity of the DFO self-assessment process. These activities are expected to avoid ‘serious harm’ to fish provided all the DFO self-assessment criteria and Measures to Avoid Causing Harm to Fish and Fish Habitat (DFO 2013c) can be met. These crossings would need to be constructed in a manner that successfully adheres to all of the conditions and mitigation measures discussed in Section 5.0 and the EPP (TERA 2014) to ensure compliance with the Fisheries Act. However, should any changes to construction methods or timing (e.g., instream construction within timing windows) occur for any of these waterbodies, a review by DFO may be required if serious harm to fish cannot be avoided.

Although it is expected no serious harm will result, it is recommended that the crossings of Pipestone Creek at SKP 971.9 (MB-WC1) and Oak Creek at SKP 1109.5 (MB-WC42) be reviewed by the NEB/ DFO due to the proposed route alignment and habitat sensitivity. The proposed route alignment parallels both watercourses along a meander bend and may not meet all the Measures to Avoid Causing Harm to Fish and Fish Habitat (DFO 2013c) in regards to site selection in the project planning section. Additional recommendations for these two watercourse crossings include implementing bio-engineered bank stabilizing measures (e.g., live willow staking) in addition to hard armouring, limiting riparian disturbance to only the right-of-way at the proposed crossing (i.e., not along the meander bend) and ensuring a qualified fish biologist is onsite to facilitate fish passage, if necessary, and conduct water quality monitoring and a fish/mussel salvage during construction.

Within Alberta, AESRD will require a minimum of 14 days notification prior to construction under the COP (Alberta Government 2013a) for the pipeline crossing methods to be implemented at the watercourse and fish-bearing drainage, wetland and lake crossings.

All watercourse and fish-bearing drainage, wetland and lake pipeline crossings in Saskatchewan will require an Aquatic Habitat Protection Permit prior to construction to meet the requirements of the Environmental Management and Protection Act, 2002.

A License to Construct Water Control Works from MCWS will be required for all the pipeline watercourse and other fish-bearing waterbody crossings in Manitoba. Provincial Waterway Authorizations from MIT are required for the crossings of the Cypress River at SKP 1143.5 (MB-WC48), Rosenheim Drain at SKP 1255.7 (MB-WC76), Buffalo Creek at SKP 1262.9 (MB-WC78) and an unnamed tributary to Buffalo Creek at SKP 1267.2 (MB-WC79) as these locations are on designated provincial waterways.

5.1.3 Contingency Pipeline Crossing Methods Trenched methods are not likely to be feasible at the proposed crossings of the South Saskatchewan, Qu’Appelle and Souris rivers (SK-WC28, SK-WC48 and MB-WC32) due to the size, streamflow, fish/freshwater mussel habitat sensitivity and bank conditions. If trenchless methods are unsuccessful or not feasible at the South Saskatchewan, Qu’Appelle and Souris rivers or at any canals/agricultural drains where trenchless methods are planned, it is recommended that a contingency trenchless crossing location be determined.

It is anticipated that the recommended methods for pipeline construction for the watercourses and other fish-bearing crossings will be successful and no contingency methods are proposed for these crossings.

5.1.4 Recommended Vehicle and Equipment Crossing Methods The construction of the replacement pipeline will also entail watercourse and other fish-bearing waterbody crossings for vehicles and equipment. Wherever practical, it is recommended that vehicles and equipment utilize existing crossings (e.g., existing bridges, culvert crossings and/or roads).

During frozen conditions, vehicles and equipment may cross all watercourses and other fish-bearing waterbody crossings using snowfills, ice bridges or clear span bridges. During open water conditions, vehicles and equipment can cross all watercourses and other fish-bearing crossings using a Type I clear span bridge, as defined by Alberta Government (2013b). The construction of these temporary vehicle

crossings is included under the Bridges, Causeways and Culverts activity of the DFO self-assessment. With the successful implementation of the appropriate conditions and mitigation measures outlined in the EPP (TERA 2014) Section 5.0 of this report and the Measures to Avoid Causing Harm to Fish and Fish Habitat (DFO 2013c) ice bridge, snowfill or clear span bridge crossing methods are expected to avoid serious harm to fish.

Within Alberta, AESRD will require notification for snowfills, ice bridges or clear span bridges as the Code of Practice for Watercourse Crossings (Alberta Government 2013b) will apply to these vehicle and equipment crossing methods.

The provincial permit applications for Saskatchewan and Manitoba will also include the vehicle and equipment crossing methods.

5.1.5 Recommendations for Nonfish-bearing Drainages There were 58 proposed nonfish-bearing drainage and wetland crossings that lacked defined bed and banks or fish habitat potential along the replacement pipeline route (Table 17). The below-mentioned pipeline, vehicle and equipment crossing methods should also be applied at all proposed nonfish-bearing drainage crossings unless specified otherwise in Appendices 8 and 10 of the ESA (i.e., Wetland Technical Report and Wildlife Technical Report, respectively) in regards to wetland, amphibian or other wildlife concerns (TERA 2014).

With the successful implementation of appropriate industry standard mitigation measures, an open cut pipeline crossing method if water is present and a standard trench method if dry or frozen to the bottom can be used. Snowfill and ice bridge vehicle and equipment crossing methods can be applied at all nonfish-bearing drainage crossings during frozen conditions. Swamp mats and/or logfills can be used for vehicle and equipment crossing methods during open water conditions.

With respect to crossing these sites, there are no anticipated regulatory requirements associated with notification or application to DFO (Fisheries Act), AESRD (Water Act) or Saskatchewan and Manitoba provincial regulators. Regulatory requirements may be required for these crossings if they are identified as wetlands. A list of wetlands is provided in Appendix 8 of the ESA (Wetland Technical Report).

5.1.6 Recommended Supplemental Surveys There are a total of 36 potential watercourse crossings in Saskatchewan and Manitoba that have not been visited by a qualified fish biologist for the Project, due to land access constraints (see Table 16 for specific locations). If landowner access is obtained, a supplemental aquatic assessment will be conducted on these proposed crossing locations in order to determine if these waterbodies have defined bed and banks and provide fish habitat, and to confirm any existing information and collect new data. Of note, three proposed crossings that still need to be visited are Wascana Creek at SKP 738.8 (SK-WC59), Cypress River at SKP 1156.2 (MB-WC49) and Deadhorse Creek at SKP 1229.0 (MBR-WC5). The results from the supplemental aquatic assessment will be included in a supplemental report.

5.2 Permanent Facilities, Temporary Facilities and Decommissioning There are no anticipated effects on watercourses and other fish-bearing waterbodies by the proposed activities at the existing permanent facilities. Therefore, there are no anticipated regulatory requirements associated with application to DFO (Fisheries Act) or any other relevant provincial and legislation unless otherwise specified in the Wetland Technical Report (Appendix 8 of the ESA).

Once the locations of temporary facilities and decommissioning activities are identified a supplemental aquatic assessment will be conducted, if necessary. Temporary facilities and decommissioning activities must also comply with all regulations mentioned in Section 1.3 of this report. The same recommendations from Section 5.1.4 apply for any additional vehicle and equipment crossings.

ZOI is variable depending on water velcocity and depth and changes seasonally (Alberta Government 2013a). 5 Historical fish presence from Atton and Merkowsky 1983, McCulloch and Franzin 1996, RL&L 1998b,c, AAR 2007a,b, 2008a (Enbridge ACEP and SLP), Milani 2013, FWMIS 2014. 6 Information from the As-Built reports for the Enbridge ACEP and SLP (TERA 2011a,b). 7 These watercourses were not assessed prior to reporting due to land access contraints, therefore information on fish species, restricted activity periods, and other characteristics is incomplete.

6.0 MITIGATION The mitigation measures for the construction of the proposed replacement pipeline watercourse and other fish-bearing waterbody crossings are provided in the EPP (Appendix 1 of the ESA) (TERA 2014). In addition, some of the mitigation measures from the EPP are also discussed in Sections 6.2.3 and 6.2.7 of the ESA (TERA 2014).

The recommendations in Section 5.0 of this report and mitigation measures included in the ESA (TERA 2014) and EPP for the Project (Appendix 1 of the ESA) were developed in accordance with the construction standards outlined in Pipeline Associated Watercourse Crossings, 3rd Edition (Canadian Association of Petroleum Producers [CAPP] et al. 2005) and the DFO Measures to Avoid Causing Harm to Fish and Fish Habitat (DFO 2013c) mentioned in Section 5.0 of this report. The guide document, Pipeline Associated Watercourse Crossings, includes an endorsement by DFO that indicates it is a compilation of modern planning considerations, best practices for pipeline and vehicle crossing construction techniques, and current environmental protection methods that are used to meet regulatory requirements across Canada and to minimize fish and fish habitat impacts associated with pipeline-related watercourse crossing activities.

To help ensure that the aquatic capacity of the watercourses crossed by the replacement pipeline segment are not compromised during instream activities, a qualified fish biologist has reviewed the mitigation measures in December 2013 and January 2014 relevant to watercourse crossings and any additional changes to these mitigation measures outlined in the EPP. It should also be noted that additional mitigation measures may be necessary pending review from various provincial and federal agencies and should be incorporated into the EPP prior to construction.

7.0 SUMMARY The proposed replacement pipeline route crosses the North Saskatchewan, South Saskatchewan, Qu’Appelle, Assiniboine and Red River basins. There are a total of 140 potential crossings including confirmed watercourses (i.e., defined bed and banks), fish-bearing drainages, nonfish-bearing drainages and those that have not been visited due to land access constraints. Key proposed watercourse crossings (i.e., relatively sensitive crossings with sportfish presence) include but are not limited to the South Saskatchewan, Qu’Appelle and Souris rivers as well as Pipestone and Oak creeks.

Bigmouth buffalo, a species listed as Special Concern under SARA and COSEWIC were captured in the Qu’Appelle River within the vicinity of the proposed crossing. Lake sturgeon (Saskatchewan River and Red-Assiniboine Rivers-Lake Winnipeg populations) are listed as Endangered under COSEWIC, however, were not captured during the aquatic assessments or have been documented near any the proposed watercourse crossings. Mapleleaf mussel are a freshwater mussel species listed as Endangered under SARA and COSEWIC but were not captured or are documented in any of the proposed watercourse crossings.

Aquatic assessments were completed in the open water season in 2013 and 2014. The aquatic assessments were completed in order to document baseline fish, fish habitat and freshwater mussel information at the proposed watercourse and other fish-bearing waterbody crossings and provide the NEB, DFO and provincial regulators with information to assist with any reviews of the Project they may need to conduct. The aquatic assessments were also completed in order to satisfy the requirements of clause (a) in Part 1 of Schedule 2 of the Code of Practice for Pipelines and Telecommunication Lines Crossing a Water Body (Alberta Government 2013a) and Code of Practice for Watercourse Crossings (Alberta Government 2013b).

The successful implementation of the recommendations in this report and the mitigation measures outlined in the EPP (Appendix 1 of the ESA) (TERA 2014) are also expected to satisfy any potential requirements associated with the applicable Alberta, Saskatchewan and Manitoba provincial legislation.

ADDITIONAL HABITAT COMMENTS Line 3 Replacement Program High salinity might be a limiting factor for fish, and a reason why no fish were caught or observed. Channel widths and bank heights were very irregular, with some banks being greater then 3 m at the railway berm. Field crew was unable to assess past 130 m downstream of right-of-way due to land access restrictions.
