Cleanup Complete Determination Issued |
DEC has determined that remaining contamination was to de minimis extent and does not pose a risk to the occupants of the building, visitors at the site, or the quality of off-site surface water. Remaining concentrations in soil are isolated and impracticable to remove from their locations adjacent and beneath the building foundations and infiltration of surface water as a transport mechanism is restricted due to building and concrete features covering the area. Based on these factors, DEC has determined there is no unacceptable risk to human health or the environment as long as the contamination is properly managed in accordance with the Institutional Controls stipulated in the cleanup complete determination and agreement page signed by Alaska Housing Finance Corporation.
This determination is in accordance with 18 AAC 75.380 and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment. |
