Northern EnviroSearch (Tulita) Ltd. (NESTL) was retained by Husky to conduct the Summer Site Inspections (SSI) and prepare a summary of their findings. Site photographs for the Slater River wellsites and monitoring (groundwater and thermistor) wells are attached. The Slater River SSI was conducted on September 16 and September 20, 2014 under mild, dry weather conditions (temperatures averaged C). Little Bear N-9 Wellsite (N64 58' 55.4", W126 31' 26.9") The N-9 wellsite is 23 km from the Government of Northwest Territories (GNWT) winter road and was constructed and drilled during the winter of 2011/2012. The site was cleared of trees using a D6 bulldozer. The bulldozer blades were elevated to reduce the potential for disturbance to the vegetative ground cover and the brush piles were mulched and spread over the lease. The winter access crosses through the centre of the wellsite and there is also asemi-circle detour around the wellsite required for non-wellsite traffic. Operational space on the lease was leveled using a snow and ice pad and minimal disturbance techniques. The well was shut in at the end of the drilling program and all surface equipment was removed. The chained well head and guard rail remain onsite. A permanent metal post with the well identification placard was installed on the well ground. In summer 2012, Husky conducted atwo-day garbage and debris clean-up of the N-9 site. During the winter of 2012/2013, Husky conducted completion activities. The well was shut in at the end of the 2012/203 completions program. A second clean-up of garbage and debris was completed during the summer of 2013.
