Problems/Comments
Soil samples were collected and tested from three trenches excavated in association with a 200 square foot area of stained soils in the center of the SRE building. Elevated levels of DRO and RRO were detected in shallow soils in 2 of the 3 trenches. Estimated volume of impacted soils is 50 cubic yards.

| 11/10/2004 | Conditional Closure Approved | DEC issued a letter stating that: The contaminated soil that was removed from the floor of the former SRE building (and additional soil generated at the airport) has been transported to the new SRE building to be used as sub-base soil. A concrete pad was placed over the sub-base soils and the new SRE building was constructed on that pad. DEC has determined that there is no risk to human health, safety, or welfare, or the environment from this contaminated material and no further cleanup action is required at this site. | David Pikul |
