Submit approval letter to the USAF on the Final 2011 Remedial Action Cleanup Report for King Salmon Airport, AK. The report describes work at two discrete locations at SA036 (DR9 and DR13). At SA036-DR9, thirteen 55-gallon drums were removed from the site along with 38 cubic yards of contaminated soil. The drums contained a solidified tar-like substance. Confirmation sample results were all below ADEC cleanup levels. At SA036-DR13, excavation of TCE and DRO contamination occurred in 2012. Eight 1-cubic yard super sacks with TCE contaminated soil was shipped off site for disposal and 13 cubic yards of POL contaminated soil was placed in the biocells. Confirmation samples from the TCE excavation area indicate that the extent of TCE soil contamination was reached. One confirmation sample collected beneath “oil reservoirs” indicate contamination remains associated with debris. Further action is required. |
