Update or Other Action |
TECH; DUPEE: Consulted with Larry Acomb, consultant for Northway LUST project, regarding CAP. He stated permafrost will not affect air sparging, soils are not as fine as initially thought; they will adjust blower to force more air through soils. Mounding not a problem, product is old with low solubility. VOCs are estimated to be low, probably won't do fertilizer and no studies are planned for microbes. Stated project will begin next May 1995. Subsequently sent letter further addressing DEC concerns over this remediation plan. |

Document, Report, or Work plan Review - other |
DEC sent comments on the draft 2021 RI and GWM WP. The Radio Range Tower, Power Plant Building, Water Treatment Building, and CAA Former Garage building will have work done at their locations.
Surface soils and surface water will be sampled for lead and PCBs at the Radio Range Tower. Existing groundwater wells will be sampled for GRO, DRO, VOCs, PAHs at the PPB and WTB AOCs. At the Garage AOC, soil borings and groundwater monitoring wells will be installed and sampled and run for all POL CoCs, with the addition of EPH and VPH for use in HRC calculations. |

Site Characterization Workplan Approved |
ADEC approved the Final RI and GWM WP for the FAA Northway sites. Soil borings and monitoring wells will be installed and sampled at the CAA Garage AOC, and the HRC will be used to assess if the contaminants exceed risk criteria. Surface soils and surface water will be sampled for lead and PCBs at the Former Radio Range Tower and other groundwater wells will be sampled at other AOCs for GRO, DRO, VOCs, and PAHs. |

Document, Report, or Work plan Review - other |
ADEC sent comments on the 2021 Draft RI and Groundwater Monitoring Report for FAA Northway Station. The report details efforts to characterize and monitor contamination at several areas of concern (AOCs). Soil borings and monitoring wells were installed and sampled at the Former Civil Aeronautics Administration (CAA) Garage AOC, also known as the Basketball Court site. The Hydrocarbon Risk Calculator (HRC) was used to assess remaining risk criteria.
Surface soils were sampled for lead and polychlorinated biphenyls (PCBs) at the Former Radio Range Tower AOC. Groundwater monitoring was conducted at five other AOCs. |
