Problems/Comments

The United States Postal Service (USPS) operated the former Iliamna Post Office at this site until the 1980s. Facilities at the site included the post office, and generator house, and two above ground storage tanks (ASTs). Investigations at this site in 1995, 1998, and 1999 identified petroleum contaminated soil and groundwater, likely associated with the former ASTs. The USPS sold this property in 2004.

6/14/2024 Update or Other Action Clarification for entry dated 4/4/2023: The cleanup level that applies at this site is the most stringent cleanup level as described in 18 AAC 75.340 and Tables B1 and B2. For almost all contaminants, the most stringent cleanup level is migration to groundwater; however, some PAHs have a more stringent human health cleanup level. The authority to close sites with residual migration to groundwater exceedances is delegated to the Environmental Program Manager 2 (EPM 2). The EPM 2 may make a site-specific determination to issue a cleanup complete determination if the responsible party presents documentation for DEC review and approval which demonstrates that soil contamination has been delineated horizontally and vertically to the most stringent cleanup levels and groundwater concentrations are below the applicable 18 AAC 75 Table C groundwater cleanup levels after multiple rounds of sampling.
