Site Closure Approved |
The Technical Memorandum for Site 24 documents the results of site reconnaissance, field screening and groundwater sampling. Site 24 is the current location of the Solid State Phased Array Radar System (SSPARS) and is surrounded by a fenced and is a highly secured area within Clear Air Force Station.
The Technical Memorandum recommends that the site be closed with no further action required. Based upon the investigation documented in the Technical Memorandum DEC is closing Site 24. This determination is subject to a future department determination that the cleanup is not protective of human health, safety, or welfare, or of the environment
Site 24 was the location of a presumed encampment during the 1940s and 1950s. No historical documentation of the site use has been found. The use is based on observations of the area documented in the Preliminary Assessment/Site Investigation (PA/SI). Two preexisting wells, battery remnants, wood-lined pits, empty 55-gallon drums, a concrete pad, roofing material, and debris were noted. Sampling and analysis during the PA/SI identified two areas with lead exceedances. Soil was removed and one confirmation sample had lead remaining at 690 mg/kg.
Several areas exhibited elevated levels of diesel range organics (DRO) during the PA/SI. The most notable was near the existing Well No. 1. When this well was sampled it A new contained 593 mg/l DRO. Three new monitoring wells were installed, one 40' upgradient and two 50' downgradient of the existing well. DRO was not detected when these were sampled. The PA/SI speculated that the well may have been used for disposal of waste oil but a limited area was affected.
The PA/SI recommended the preexisting wells be abandoned, additional soil removal where lead was found in the confirmation sample and screening of surface soil during the construction of the SSPARS with soil removal as necessary.
During the excavation of a sewer line trench in 1998 stained soil with a strong hydrocarbon odor was noted. In 1999 four boring were advanced and field screened. The field screening did not indicate any contamination; confirmation samples at the bottom of the borings did not detect DRO or BTEX.
The 2007 investigation the field team noted that the area had been graded and areas identified during the previous investigation were no longer present. Field screening was conducted for metals and petroleum and nothing of note was detected. Groundwater samples were obtained from the drinking water well for the SSPARS, the cooling water supply well and the analysis did not detect any contaminants of concern.

Update or Other Action |
SPILL NOTIFICATION: Historic Spill #1 - During construction, historical contamination was found. No soil was excavated. This site was backfilled without ADEC approval. No confirmation samples were taken. PPR was made aware of this site from the Division of Water, who provided a map of the site and PID readings of 265PPM at 8' depth. Location: 64.300258, -149.187524 |

SPILL NOTIFICATION: Historic Spill #4 - During construction, historical contamination was found. Approximately 15 cubic yards of soil was excavated and sampled by ECC. Stockpile was transported to OIT for incineration. Location: 64.299068, -149.188244 |

Update or Other Action |
Historic contamination was discovered in the footprint of IRP Site 24 (SS024) in 2018. USAF submitted spill notifications and then advised that those notifications were submitted in error since the contamination was located on a closed site. Based on a historic document review, Site 24 (SS024) has not been properly characterized and should not have been closed. DEC anticipates that the site will be reopened. |

Site Reopened |
In May 2008, Site 24 was closed based on the results of field screening activities rather than analytical data. The site remained closed until 2018, when contamination was discovered in four separate areas within Site 24. Based on a file review and the recently encountered contamination, DEC is reopening the site. |

Document, Report, or Work plan Review - other |
DEC has reviewed the Draft Limited Site Inspection (SI) Report for CD027 and SS024, which details sampling in surface and shallow subsurface soils to assess if further sampling or remedial investigation is required, or if the site can be eliminated from further consideration. No groundwater was assessed as part of this SI.
Forty soil borings were collected and analyzed for gasoline, diesel, and residual range organics (GRO, DRO, RRO), volatile and semi-volatile organic compounds (VOCs, SVOCs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), pesticides, and metals. The report recommends that Site CD027 be reevaluated if the land use change is proposed, and Site SS024 be eliminated from further consideration as petroleum contamination did not exceed the project screening levels and non-petroleum analytical results are not indicative of an uncontrolled release.
DEC does not concur with the elimination of SS024 from further consideration and anticipates further work being necessary at both of these sites. |
