6.3C1.0 INTRODUCTION Golder Associates Ltd. (Golder) is supporting Wataynikaneyap Power L.P. (Wataynikaneyap) with the Phase 1 New Transmission Line to Pickle Lake Project (the Project) environmental assessment (EA). Golder and Wataynikaneyap met with the Ministry of Natural Resources and Fisheries (MNRF) on March 9, 2017 to review the bat survey results from 2016 for the Project. During discussions at the meeting, it was suggested by the MNRF that Wataynikaneyap complete an acoustic assessment of bat activity at potential bat maternity habitats previously characterized in 2016 to support the EA. Wataynikaneyap agreed to complete a survey between the submission of the Draft EA Report and Final EA Report. The additional field work is intended to provide confidence in the results of the bat maternity habitat baseline that was previously characterized by aerial surveys in the spring of 2016. Project laydown and construction camp areas along the right-of-way (ROW) were assessed via helicopter for hibernacula potential. This memorandum presents the results of the survey.
6.3C2.0 METHODS 6.3C2.1 Acoustic Assessment This field program was completed to confirm “regular and frequent” occupancy at habitats classified as high or moderate snag density, while low snag density habitats were also surveyed for comparison. No effort was made to assess areas in the “none” category for snag potential (e.g., open areas or areas with few snags). The acoustic study was comprised of:
Installation of one bat detector per candidate maternity roost habitat, with a total of 20 candidate sites divided amongst the high, moderate and low habitat types and the Preliminary Proposed and Alternative corridors local study areas (LSAs) (Table 6.3C-1; Figure 6.3C-1). The LSAs for each corridor include a 500-m buffer around the 2-km-wide corridor and a buffer of 500 m around connection facilities, transformer station, laydown areas, construction camps, and new and existing access roads.
Detector placement focused on habitat edges, corridors or feeding areas adjacent to the habitat. Effort was not distributed equally along the lengths of the Preliminary Proposed and Alternative corridor alignments due to logistical constraints. Effort was focused on areas that included higher densities of moderate and high snag potential, which are limited in extent compared to the other habitat types.
Wildlife Acoustics full-spectrum bat detectors were deployed to collect at least 14 nights of acoustic monitoring from June 29 or 30, 2017 through July 23, 2017.
The acoustic data were analyzed and vetted using Sonobat 4.1 call analysis software, to assign bat call passes to species or group levels where appropriate.

APPENDIX 6.3C 2017 Bat Field Survey Results
October 2017 Project No. 1535751 7
Data analysis was conducted by Dan Coffen (Biologist, Adv.Dip., Golder) and reviewed by Mitch Firman (Wildlife Biologist, M.Sc., Golder), who have extensive experience analysing bat acoustic signals. Mr. Coffen received formal training in the identification of bat echolocation auditory signatures using Sonobat (instructor Janet Tyburec at Bat Survey Solutions) during the 2017 Acoustic Survey Methods training course. Mr. Firman received formal training in the identification of bat echolocation auditory signatures using both Analook (instructor Chris Corben) and Sonobat (instructor Joe Szewczak) during the 2012 Bat Conservation International Monitoring Workshop. The analysis was completed using Sonobat software and consisted of a tally of all bat passes, where a bat pass is attributed to a bat flying through the detection radius of the bat detector, and assigning the passes to bat species or species group based on characteristics of the echolocation recording (Lausen 2008). Species groups were as follows:
high frequency, which may include various species of the genus Myotis (little brown myotis [M. lucifugus], or northern myotis [M. septentrionalis]) and red bat (Lasiurus borealis);
low frequency, which may include hoary bat (Lasiurus cinereus), silver-haired bat, and big brown bat (Eptesicus fuscus); and
unknown, which includes calls that could clearly be identified as a bat, but could not be identified to species or species group due to recording quality or because the characteristic frequency fell between 30 and 35 kilohertz (kHz).
Because an individual bat may be recorded making multiple passes, the data presented are a measure of bat activity in the vicinity of the bat detectors, not a direct measure of the numbers of bats within or passing through the LSA for each corridor. Data were summarized by night and by detector.
6.3C2.2 Hibernacula Assessment Project laydown and construction camp areas along the ROW were assessed from the helicopter for hibernacula potential using the following criteria for exclusion as a candidate hibernaculum (PGC and USFWS 2012):
There is only one horizontal opening, and it is less than 15 cm in diameter, and no or very little airflow is detected.
The opening is a vertical shaft less than 0.3 m in diameter.
The passage continues less than 15 m and terminates with no fissures that bats can access (this assumes the passage is safe enough to enter and has been thoroughly inspected).
The mine is prone to flooding, collapsed shut and completely sealed, or otherwise inaccessible to bats.
It is a “new” opening, which has occurred recently (less than 1 year old) due to subsidence.
The six potential hibernacula locations that were identified along the Preliminary Proposed Corridor and the Alternative corridor ROWs during the aerial bat habitat assessment in 2016 will be visited during the week of September 11, 2017 to determine their suitability as potential hibernacula using the criteria listed above.
APPENDIX 6.3C 2017 Bat Field Survey Results

6.3C3.0 RESULTS 6.3C3.1 Acoustic Assessment Bat detectors were distributed amongst low, moderate, and high potential maternity habitats and amongst the Preliminary Proposed Corridor and the Corridor Alternatives (Figure 6.3C-1, Table 6.3C-2). The bat detector at plot BM01 (Figure 6.3C-1) malfunctioned and did not record any data; all other bat detectors recorded data for 24 or 25 nights (Table 6.3C-2).
Over the entire survey period, a total of 2,997 bat passes (4.8 bat passes/night) were recorded (Table 6.3C-2, Table 6.3C-3). Most passes were hoary bats and unspecified low frequency bats (Table 6.3C-2), which represented 29.7% and 29.2% of total bat passes, respectively.

APPENDIX 6.3C 2017 Bat Field Survey Results
October 2017 Project No. 1535751 13
The total number of bat passes recorded per detector per night ranged from 0 to 47.7, and averaged 4.8 across all detectors combined (Table 6.3C-3). The highest activity levels were recorded at detector BM16, which is located in the Preliminary Proposed Corridor LSA (Table 6.3C-2, Table 6.3C-3; Figure 6.3C-1). Most of the activity at this detector was by hoary bats. This detector was adjacent to a road, which may be functioning as a travel corridor between foraging and roosting sites.
Little brown myotis, a federal and provincial species at risk, was recorded at six detectors and in the Preliminary Proposed and Corridor Alternatives LSAs, with relatively higher activity at detector BM15, which is in the Preliminary Proposed Corridor LSA (Table 6.3C-2, Table 6.3C-3). Northern myotis is also a federal and provincial species at risk and was recorded at one detector in the Preliminary Proposed Corridor LSA (BM16; Table 6.3C-2, Table 6.3C-3).
6.3C3.2 Hibernacula Assessment There were two potential hibernacula locations noted within laydown and construction camp areas along the Preliminary Proposed Corridor ROW. These sites were determined to have no potential as suitable hibernacula as the noted areas were flat, solid bedrock features (Photo 6.3C-1 to Photo 6.3C-3).
