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. |
