A letter dated April 20, 2010 from SHN Consulting Engineers and Geologists outlines the schedule for the cleanup. A Remedial Action Work Plan (Site Wide) is due to be completed by April 2012. There is a particular area of interest that will be looked at sooner. The Remedial Action Plan for it will be implemented according to the schedule by July- Sept. 2011.
