3.0 ENVIRONMENT

3.1 Environmental Issues

During clearing activities on January 7, 2021, within SW 11-70-8 W6M a feller-buncher brought down a large deciduous tree. After the tree was on the ground, the clearing crew inspected the area of the felled tree and found a deceased black bear lying next to the tree. Clearing activities were immediately shut down by the contractor undertaking the work and notified NGTL. Immediately after being notified, NGTL’s lead Environmental Inspector was dispatched to the site to confirm details of the incident. Alberta Environment and Parks (AEP) Land Use Officer, Senior Wildlife Biologist and Fish and Wildlife officer were informed about the incident on January 7, 2021. Post-incident evaluation by the Alberta Fish and Wildlife officer identified an entrance approximately 40 feet above ground to the hollow interior of the tree. The Wildlife officer concluded this hollow was being used as a den. NGTL conducted a bear den sweep through the area by a NGTL-contracted environmental consultant and Indigenous participants in advance of construction and in adherence to the appropriate methodology and did not identify a bear den in the relevant area. While the denning location is considered uncommon, future den survey crews will be requested to be vigilant for large over-mature trees, and signs of bear climbing and potential denning activity. NGTL notified the CER of the incident by
