Leaking Underground Storage Tank Release Confirmed - Petroleum |
LUST Site created in CSP for source area ID 78070 RPCON replaced approx. 125 cu. yds. contam. soil back in the pit w/recommendation that site be managed consistent w/other Kotzebue airport sites that have petroleum contamination. Highest soil levels GRO= 3,000 ppm, Benzene= 6.5 ppm, Total BTEX= 108 ppm. |

Document, Report, or Work plan Review - other |
In response to the ADEC letter in Feb 2000, the RP submitted soil samples to Columbia Analytical in June of 2000. Samples were analyzed for GRO 700mg/kg, DRO 698 mg/kg, benzene 10 mg/kg, toluene 6.0 mg/kg, ethylbenzene and xylenes were below cleanup levels. Samples were also submitted for PAH analysis, all analytes were below cleanup levels, most were non-detect. No groundwater results were submitted to ADEC. |

Update or Other Action |
Sent letter to Crowley requesting status of site and/or additional site characterization as a result of exceedances in TAH and TAqH in porewater samples along the Kotzebue Sound and Kotzebue Lagoon. |

Conceptual Site Model Submitted |
DEC received from Oasis the Conceptual Site Model for the Kotzebue site. A human health exposure pathway via soil media (including incidental soil ingestion and inhalation of outdoor air) is complete for commercial/industrial workers, site visitors, and construction workers. Exposure pathway by ingestion of groundwater is not considered complete because the aquifer is not used for drinking water. Human health exposure pathway by ingestion of surface water is not considered complete because the surface water is not a viable drinking water source. However, DEC considers this pathway complete because surface water is used recreationally and incidental water ingestion may occur. Groundwater has not been sampled atthe site since 2000. Status of contamination is currently unknown. |

Site Characterization Workplan Approved |
DEC received and approved Oasis Groundwater Characterization Workplan. Oasis proposes installation of new wells to replace the destroyed wells. |

Document, Report, or Work plan Review - other |
DEC received and commented on the Site Characterization Report. Contamination above DEC cleanup levels is still present in groundwater.
Similar comments to those from January regarding the submitted conceptual site model were provided. |

Document, Report, or Work plan Review - other |
DEC received sampling results collected from pond adjacent to the site. Groundwater samples could not be collected since wells were still frozen. Surface water samples indicated an exceedance of TAH. Surface water at the pond was determined to be fresh water and not brackish. |

Update or Other Action |
DEC received and reviewed the Groundwater Monitoring Work Plan for 2012. Comments to the work plan have been submitted. Revised version is pending. |

Document, Report, or Work plan Review - other |
DEC received the September 2011 Groundwater Monitoring Report. GRO and benzene concentrations in wells MW-1 and MW-3 excedeed DEC cleanup levels. DRO also exceeded cleanup levels in well MW-1. |

Meeting or Teleconference Held |
DEC met with Penny Adler, Sam Myers, and Mike McCarroll at DOT to discuss contamination associated with the Kotzebue Airport. During the meeting, DEC discussed what is known about petroleum-contaminated water and migration to the Kotzebue Sound and the Lagoon. DEC is no longer investigating the contamination through state funding, and will be working with lease lot RPs to identify the sources of contamination and attempt to cleanup contamination through source removal. Lease agreements, lease lot histories, and deterrents to investigations were discussed. |

Meeting or Teleconference Held |
ADEC staff met over a teleconference with Crowley staff and their QEP to discuss progress at both sites and how to go forward. Lot M, Block 1 requires additional site characterization and follow up with location of historic spills or tank releases. The UST site will require location of the monitoring wells that were used historically. |

| 12/13/2018 |
Document, Report, or Work plan Review - other |
ADEC staff reviewed the 2013 report "September 2012, Groundwater Monitoring Report; Kotzebue Airport - Crowley" for work conducted previously. Groundwater monitoring wells around the site were sampled and diesel range organics, gasoline range organics and benzene were found above groundwater cleanup levels. |

Workplan Requested |
A letter was sent to the Kotzebue Airport Alaska Department of Transportation & Public Facilities requesting a work plan to remediate continuing movement of contaminants into area surface waters from the airport. |
