9/20/2012 Document, Report, or Work plan Review - other Approved the final injection well closure report documenting the permanent closure of floor drains at Building 300 and Building 302. Building 300 had a floor drain sump connected to an outfall pipe that discharged to a septic crib. The outfall pipe was plugged and the sump filled with clean material and capped with concrete. Results from the sample collected from the floor of the septic crib show results for diesel range organics and arsenic above the cleanup level. Building 302 had a floor drain that discharged to a septic crib. The floor drain was closed during building renovations in 1983. Results from a sample collected beneath the bottom of the septic crib show diesel range organics and arsenic above the cleanup level. Melody Debenham

3/1/2019 Document, Report, or Work plan Review - other DEC Approval – Former Bethel Airport Infrastructure Removal and Release Investigation. Areas of concern include: LMM, FAA Complex Housing Well House, and FAA Housing Laydown Yard. As no contamination in exceedance of cleanup levels (no likely contaminant releases in the case of the FAA Housing Laydown Yard) was documented at these areas, DEC concurs with the recommendation of no further action for these locations. Areas of concern at the Former Bethel Airport include: Control Towers, Radio Range, Utility Building, and Engine Generator Building, Asphalt Batch Plant, and Crowley Marine Building Drums areas. DEC concurs with the recommendations to preform remedial actions at all of these areas of concern, excluding the Utility Building due to exceedances of lead, GRO, DRO, RRO, VOCs, and PAHs.
