Document, Report, or Work plan Review - other |
The initial Site Characterization Report (Interim Cleanup Action Report) completed in May 2008, was not accepted by DEC (PERP) due to issues with report consistency, sample location tracking, and a general lack of information typically included in reports of this nature. Following several revisions based on comments submitted by DEC, the final revision was submitted in June 2009 and was also rejected because many of DEC's comments were not addressed leaving several issues unresolved. Regardless of the status of this report, certain information can be ascertained from the information provided, namely: Two, 5,000-gallon unregulated heating oil USTs were removed from a common excavation at the site in 2007. Bedrock was found from 6-16 feet bgs. perched groundwater entered the excavation and was found with floating product immediately beneath the former tanks. Confirmation samples indicate all contaminated material was removed from the excavation down to the bedrock surface, however test pit samples indicated DRO at concentrations above the migration to groundwater cleanup level remained in an area NW of the original excavation. The excavation was backfilled with clean material and excavated material with PID readings below 25 ppm. Five stockpiles of contaminated material remain at the High School awaiting final disposal/treatment. |

Reviewed Contaminated Soil Stockpile Work Plan for Kodiak High School dated June 2009. The objective is to characterize the 1,600 cy of soil remaining in 5 stockpiles at the high school and transport the soil to a staging/treatment area. The proposed soil characterization would consist of field screening with a pid at the rate of one screen per 25 cy, petroflag screening from 10-20 individual locations, and the collection of 20 discrete soil samples for laboratory analysis of DRO, GRO, and BTEX. This work has so far not been conducted as of 5/20/2010. |

Document, Report, or Work plan Review - other |
Reviewed and approved revised Contaminated Soil Stockpile Work Plan for Kodiak High School. Soil stockpiled at the HS will be transported to KIB-owned Lot 2A, Lakeside subdivision where it will be segregated based on suspected contaminant concentration and sampled to confirm. The material will be power screened to remove the 2-inch+ material which will be set aside. Screening, segregating, and stockpiling will be conducted on liners, with the expectation that contaminated soil will be landfarmed in accordance with a separate landfarming work plan either in Fall 2010 or Spring 2011. |

Reviewed Remedial Action Work Plan, KHS Soil Remediation Project. Approximately 1,600 cubic yards of material was transported to the Selief Lane Site, where the 2-inch plus material was screened out leaving approximately 1,300 cubic yards of impacted material. Each of the 23 samples collected contained DRO above the Method Two Migration to Groundwater cleanup level with a maximum concentration of 2,500 mg/kg. GRO was not detected above the cleanup level and benzene was not detected. This material was placed into lined, covered cells and will be landfarmed in a lift approximately 1-foot thick in December 2010, tilled, then tilled again in Spring 2011. A fence will be constructed to control access to the landfarm area and straw waddles will be placed around a nearby storm drain to control runoff. Though not included in this work plan, it is anticipated that at least one more sampling event will be conducted in 2011. |

Reviewed Contaminated Soil Sampling and Analysis Plan for Kodiak High School Soil Remediation Project. The landfarmed soil was tilled in 2011 and 2012. One field screening sample will be collected for each 40 cy of soil and the ten samples with the highest PID results will be submitted for laboratory analysis for DRO and RRO, and the two samples with the highest field screening results will also be analyzed for GRO and BTEX. |

Reviewed 2012 landfarm confirmation sampling information. The landfarm area was divided into a grid and 81 soil samples were collected and screened in the field using a PID. The ten samples with the highest PID readings plus one duplicate were collected and analyzed for DRO and RRO and the two samples with the highest PID readings were also analyzed for GRO and BTEX. PID readings for these samples ranged from 10.6 to 24.5 ppmv. GRO, RRO, and BTEX were not detected. DRO concentrations ranged from 668 mg/kg to 1,690 mg/kg. |

Soil that was landfarmed at the Selief Lane site was collected and disposed of at the KIB landfill on 12/31/12 in accordance with the approval granted by the ADEC Solid Waste Program. |

Cleanup Complete Determination Issued |
The Alaska Department of Environmental Conservation, Contaminated Sites Program (ADEC) has completed a review of the environmental records associated with the Kodiak High School Heating Oil Tank (HOT) site located at 722 Mill Bay Road in Kodiak, Alaska. Based on the information provided to date, it has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and this site will be closed. |
