Update or Other Action |
Incinerator: Request for Additional Action. An incinerator was located near Building 103 and was fueled by a 500-gallon diesel underground storage tank. The tank (9-C-3) was removed in 1995 along with 1-1/2 cubic yards of petroleum-contaminated soil. Four confirmation samples were collected and showed that the petroleum hydrocarbon concentrations were below default cleanup levels. Site Cleanup and Investigation Report, dated 1996, documented the removal of the incinerator and ash from within. Three samples were collected and showed concentrations of arsenic and lead above the department's cleanup levels. Dioxin was also present. ADEC requests FAA conduct additional characterization in the soils around the incinerator in order to determine if the contaminants are present at unacceptable levels due to migrating ash. ADEC letter dated November 21, 2005. |
