Document, Report, or Work plan Review - other |
DEC approved a UVOST Site Investigation Work Plan submitted by the U.S. Army Corps of Engineers. The Work Plan proposes to use Ultraviolet Optical Screening Tool (UVOST) to investigate potential and known release areas from former USTs. The investigation area includes the UST locations associated with DEC File Number 100.26.003 and 100.26.172. |

Document, Report, or Work plan Review - other |
DEC provided review comments for the Draft 2011 UVOST Site Investigation Report, Chena River Lakes Flood Control Project, North Pole, AK, January 2012. Based on the review DEC requested additional temporary well points and/or an up-gradient monitoring well be installed to the north of the contaminant source area in order to verify the groundwater flow direction and to address any groundwater characterization data gaps. |

Document, Report, or Work plan Review - other |
ADEC received the Final 2011 UVOST Site Investigation Report. The report concluded that two areas are impacted by DRO contamination in soil above Method two cleanup levels. One area on the northwest corner of the project office is estimated to contain 460 cubic yards of weathered arctic grade diesel (the report states that the contamination is likely a result of former military operations at the site Nike Site Tare). A smaller area was estimated to contain 55 cubic yards of DRO contaminated soil. The report recomends further evaluation/site characterization prior to a removal action. The report also concludes that groundwater at the site should be further evaluated. One of five groundwater samples encountered DRO contamination above the Table C cleanup level. No down-gradient groundwater samples have been collected. Installation of permanent monitoring wells were recomended for the site. |

DEC Staff contacted Andrea Elconin of USACE to determine project status. To date, no work schedule has been established. |

Update or Other Action |
USACE provided an update to project status: USACE will issue an Inventory Project Report (INPR) to determine eligibility for the Formerly Used Defense Sites (FUDS) program. It will take several months to prepare that report and make a determination on eligibility. Therefore no cleanup work will occur on this site in 2015. |

Update or Other Action |
Hazard ID 736 with the site name "Chena Lakes Nike Site" was determined to be a duplicate of this site (Hazard ID 24156, site name "ACOE - Chena Lakes Nike Site). Hazard ID 736 was therefore deemed "non-qualifying" in ADEC's CS database. |

Teleconference with U.S. Army Corp of Engineers (USACE) project manager to discuss project status. Federal funding requested for additional site characterization by USACE. |

Site Characterization Workplan Approved |
This Sampling and Analysis Plan (SAP) has been prepared for the Pavement Improvements Chena
River Lakes Flood Control Project by Travis/Peterson Environmental Consulting, Inc. (TPECI).
This SAP outlines the environmental tasks, including field screening and analytical sampling,
required to ensure appropriate measures are taken to protect worker health and safety, prevent
mixing of potentially contaminated media with uncontaminated media, document any encountered
contamination, and ensure compliance with applicable hazardous waste designation, storage, and
disposal regulations. |

Site Characterization Report Approved |
The Pavement Improvements Chena Lakes Flood Control Project is separated into four work areas. Areas 1 and 2 are not located within the boundaries of a contaminated site. Area 4 was not awarded. However, Area 3 is located within the boundaries of a contaminated site mapped as Department of Environmental Conservation (DEC) File ACOE – Chena Lakes Nike Site and ACOE – Chena Lakes Flood Control Project (DEC File # 100.26.003 and 100.26.172).Soil screening and analytical sampling confirm that the sidewalls of the contaminated excavation area are clean from a regulatory standpoint. Petroleum, oils, and lubricant (POL) related contamination (naphthalene) remains in the base of the excavation at a concentration that exceeds the DEC Cleanup Level. |

Workplan Requested |
Additional site characterization was requested at the ACOE-Chena Lakes Nike Site to determine the nature and extent of soil and groundwater contamination associated with the former 20,000-gallon UST removed from the site in 1989. |

Compliance Advisory Letter |
DEC sent a Compliance Advisory Letter to USACE for failure to comply with 18 AAC 75.370(b), which specifies that a responsible person, owner, or operator shall obtain approval before moving or disposing of soil subject to the site cleanup rules. In September 2024, a Contaminated Media Transport and Treatment or Disposal (TTD) Approval Form was submitted to DEC for approximately 30 cubic yards of contaminated soils generated from a construction project that occurred within the boundaries of the ACOE-Chena Lakes Nike Site and the Chena Lakes ACOE Office site. Upon review, DEC determined that construction had been conducted within the boundaries of these two active contaminated sites, without knowledge or approval and in violation of 18 AAC 75.370(b). The letter has been transmitted to USACE with a request for coordination prior to initiation of all future construction projects within the boundaries of active contaminated sites. |
