Objectif(s): The purpose of this project at the Tuktoyaktuk Base Camp is to sample soil, surface water and groundwater in the area; sample and characterize materials in Seacans; investigate and characterize landfill waste; investigate soil impact, residual fluids in tanks, and potential historical spill areas - as well as inspect the docks and assess the condition of infrastructure.

Imperial Oil intends to decommission and clean up the Tuk Base Camp lease over several years, with work beginning in the summer of 2007. The following plan summarizes proposed on-site activities scheduled for 2007 o Complete dock safety inspection and ladder repair / placement. o Complete underwater survey in the vicinity of the docks. o Investigate landfill area to characterize waste and confirm volumes o Investigate tank farm area for residual fluids in tanks, soil impact within bermed area. o Investigate potential historical spill areas. o Conduct a condition assessment for infrastructure o Sample drilling materials in Seacans & characterize waste for off-site landfill disposal. The program for the site is tentatively scheduled for August, 2007 and will take approximately 4 weeks to complete. Personnel and equipment will access the site by boat with personnel returning to the Hamlet of Tuktoyaktuk daily. All project-related equipment and materials used at site will be loaded onto the barge and transported to Tuktoyaktuk at the end of the project and where necessary, transported to an appropriate licensed disposal facility in Inuvik, Alberta or BC. Dock Inspection - A visual inspection of the dock will be conducted as part of the proposed 2007 activities. Divers will be used to inspect submerged portions of the dock. The inspection will include: identification of any safety issues associated with the use of the dock; dock integrity; completion of any necessary repairs, including repair or replacement of the ladder; and an inventory of debris in the river and nearby creek. Visual Site Inspection and Surficial Site Cleanup - A visual site inspection will be conducted as part of the proposed 2007 activities. The site inspection will include documentation of: any visible or partly buried debris (e.g. plastic, metals) and / or surface staining and condition of existing structures; the number, condition and accessibility of seacans, and sampling of the seacans contents for laboratory analysis and identification; tanks in the Tank farm containing residual fluids, and sampling of these fluids; qualitative information needed for future planning such as the condition of vegetation, areas of surface erosion / slumping, gravel pad dimensions and appropriate staging areas for equipment and materials for future work on-site, if necessary. Soil Sampling - Sampling of soils in the landfill and tank farm areas, and in areas of previously identified hydrocarbon staining will be conducted using a backhoe, hand auger and/ or auger drill rig. Sample locations and depth will be dependant on surface soil conditions, accessibility (i.e. surface slope, vegetation or the presence of standing water) and the presence of surface obstructions e.g. berms, tanks etc. Soil samples will also be collected from undisturbed locations expected to be representative of native conditions. Collection of background samples will ensure that soil analytical results can be compared to site-specific natural soil chemical and / or physical conditions. Surface water sampling - Surface water samples will be collected in 2007 from the area of the Sewage Lagoon and any other standing water bodies on and adjacent to the site to assess water chemical parameters. Surface water samples will be collected by hand using a sampler with an extendable handle and placed in laboratory provided containers for the selected analysis. Analyses of the samples will include: routine potability, total Metals, BTEX and F1 Petroleum Hydrocarbons, F2 Petroleum hydrocarbons, and on-site measurements of field electrical conductivity (EC), pH and temperature. Groundwater sampling and piezometer installation - Groundwater samples will be collected from all of the unfrozen piezometers (9) installed at the site in 2001. Additional piezometers may also be installed to allow for sampling of groundwater in the vicinity of potential contaminant sources and potential surface water receptors. Fieldwork will be conducted from August 1 to December 31, 2007 at the Tuktoyaktuk Base CampPresident, Tuktoyaktuk Hunters and Trappers Committee, P.O.
