Document Description
The proposed Interim Removal Measure (IRM) planned for 2010 at the Ascon Landfill site includes removal and disposal, or if feasible, recycling of the tarry materials from two interior lagoons in the southwest zone of the Ascon site that received oil production waste during the landfill's operation. The purpose of this action is to enable assessment of the materials underneath the tarry materials in Lagoons 1 and 2. As a result of the Landfill's history of receiving asphalt, concrete and other construction debris after it stopped receiving oil production waste, it is expected there are materials of unknown size and composition in and under the lagoons. A more complete assessment of Lagoons 1 and 2 will allow for an informed remedial construction effort during the final remedy in a manner that is protective of public health and safety and the environment. The maximum volume of material to be removed is 70,000 cubic yards, inclusive of any additives needed to dry the tarry materials for transport.
