9/10/1996 Update or Other Action UPD; Reviewed a site assessment report. Before an in-situ treatment can be designed, the extent of the soil and GW contaminant plume needs to be defined. As recommended in your report, additional soil borings amd monitor wells are needed. Therefore, a plan is needed depicting the proposed additional site assessment work. This plan needs to be submitted for review and approval by no later that 10/15/96. * Not Assigned

1/12/2005 Conditional Closure Approved Record of Decision along with cover letter explaining Department's decision to conditional close store were sent to Dennis Illies, Ralph Hulbert, and the present store manager. Todd Blessing
1/12/2005 Institutional Control Record Established ADEC has determined that no further remedial action is required at this site even though low levels of hazardous substances remain in soil above the established cleanup levels. The contaminant levels that remain there will degrade over time through natural attenuation. This determination is based on information presented to date and is subject to the following conditions: 1. any proposal to excavate and/or transport soil from the area requires ADEC approval in accordance with 18 AAC 78.274(b); 2. this site shall be listed in the Department’s database as a conditional closure with applicable restrictions and/or conditions; and 3. if future information indicates contamination is present at levels that may pose a risk, additional assessment and/or cleanup action may be required.
