Barrel Shed Remediation and Replacement Project Summary.The Barrel Shed is located at the Lake Hazen Camp in Quttinirpaaq National Park on Ellesmere Island, Nunavut. The closest community is Grise Fiord approximately 600km away.Parks Canada wants to document and dismantle the Lake Hazen Barrel Shed and remove the barrels from the park and to install a storage unit that meets health and safety and storage requirements of the site. Some large pieces of equipment, ie) engine and bulldozer blade beside the barrel shed will also be removed and taken out of the park for disposal.The existing barrel shed is a risk to staff occupational health and safety as it is a confined space. Fuel vapours from the barrels cause poor interior air quality and the irregular shape of the structure makes it difficult to organize and locate items. There is no ventilation, no windows, or lighting in the structure.The barrel shed was constructed in the 1960’s by the Defence Research Board and is designated as a cultural resource by the Parks Canada Agency. As such a Cultural Resource Impact Assessment will be conducted and determine appropriate measures to document the structure prior to it being dismantled. The shed skin will be removed. Barrels will be unstacked using a manual barrel hoist and emptied on site the level the footprint of the shed or airstrip. Empty barrels will be flown out of the park for disposal. Foot print will be levelled. A small amount of soil from the barrels is contaminated with fuel. The contaminated soil will be deposited into the existing land farm for treatment.Materials and equipment flying in and out of the park will be shuttled from the site to the airstrip by snowmobile and qamutik, UTV or ATV and trailer. Currently, all other structures in camp are at capacity, a new shed will be erected on a new foot print. The new shed will act as cold storage for food, equipment, and non-burnable waste until it can be flown out. The approximate footprint of the barrel shed is 8.5m x 5.0m. The new shed will be approximately 4.5x4m and will have wood footings and a plywood floor.The project will begin in May of 2021 and is expected to take place between May and August annually until 2023. However, it may take additional seasons to fly out the remaining empty barrels. Staffing levels are estimated at 2 park staff with 15 days on site, and 2 field unit staff, with 10 days on site in 2021 and 2022. Successive years will only require regular staffing of the camp. Existing infrastructure at the Lake Hazen camp (ie kitchen with water and grey water systems, sleepers, toilets and incinerator) will be used by staff conducting work on site. Black human waste and burnable garbage are incinerated on site via an industrial diesel fired unit. Non-burnable garbage is packed and stored in animal proof containers / buildings until it can be flown out.All personnel, materials, equipment and waste that cannot be managed on site are brought in and out of camp by twin otter fixed wing plane or helicopter. Lake Hazen camp is a Zone 3 site that allows for mechanized travel. Snowmobile and qamutik, ATV/trailer or UTV will be used to shuttle materials around camp, to and from the airstrip and landfarm. A gantry crane and chain hoist will be used to remove the top layer of barrels to the ground and extract the ground level barrels. A grinder may also be required to cut large/heavy pieces of old equipment into manageable sizes to remove them by plane. (ie: bulldozer blade, engine and push frame). Empty Barrels will be flown out to Resolute Bay where they will be cleaned, crushed and sent for disposal. The Quttinirpaaq Joint Park Management Committee voted in favour on February 14 2017 and was on site in 2018 and supports the removal of the barrel shed and the construction of a smaller, safe storage shed.
