Title

Interim Removal Measure Workplan for Ascon Landfill Site

Description

The proposed Interim Removal Measure (IRM) planned for 2010 at the Ascon Landfill site includes removal and disposal, or, if feasible, recycling of up to ~ 70,000 cubic yards of tarry materials from two interior lagoons in the southwest zone of the Ascon site that received oil production waste during the landfill's operations. The purpose of the IRM is to enable assessment of the material underneath the tarry materials in Lagoons 1and 2. After on-going construction IRM activities within Lagoons 1 and 2, it has been determined that removal of materials from Lagoon3 will be necessary to ensure the stability of the existing berm between Lagoons 2 and 3. In comparison to the IRM activities described in the Final MND and Modified IRM Proposal (analyzed in Addendum No 1), the loading area for the Lagoon 3 Proposal would not be located closer to the site perimeter than existing onsite roads used as part of ongoing IRM activities, the traffic count of haul trucks will not change, off-site haul routes will not change, the construction schedule will not change, and the maximum volume of removable materials during the IRM (70,000 cubic yards) will not be exceeded as stated in the Final MND. Further, the Lagoon 3 Proposal will comply with the same regulatory requirements and implement the same components in the IRM Workplan that serve to minimize impacts on the environment.
