Document, Report, or Work plan Review - other |
Karluk Site Characterization Work Plan reviewed and approved on this date. The revised work plan details the screening and sampling to delineate the vertical and horizontal extent of contamination by drilling 8-10 boreholes utilizing a minute man drill rig. The rig will be fitted with a split spoon and used to drill to approximately 20 feet bgs. Samples are to be taken at the highest PID reading, as well as at a deeper depth in order to delineate the vertical extent of contamination. The samples are going to be tested for Gasoline Range Organics, Diesel Range Organics, Benzene, Toluene, Ethylbenzene, and Xylenes, with 10% of samples also being submitted for polycyclic aromatic hydrocarbon analysis. ADEC approves of the work plan but provides the following comments: Under section 3.1 the work plan states that rocks will be removed via a sieve from samples. As agitation from sieving could potentially influence volatile readings, rocks should be removed with a spoon while gathering the sample;
According to ADEC field sampling guidance, de-ionized water is to be used for decontaminating equipment. The work plan has called for not using de-ionized water both in decontaminating equipment or equipment blanks due to its operational burden. It should be noted that not utilizing de-ionized water for decontamination does have the potential to bias the sample results and not utilizing equipment blanks means any bias would not be documented.

Site Characterization Report Approved |
September 2017 site characterization report approved on October 11, 2017. Fieldwork was conducted on August 6 through 8, 2017 and generally consisted of advancing ten soil borings and collection samples for field-screening and laboratory analysis. Petroleum-contaminated soil remains above applicable cleanup levels between 5 and 15 feet below ground surface, and within 30 horizontal feet of the Karluk School. Work plan deadline extended one month to December 15, 2017. |

Update or Other Action |
Contaminated soil removal plan approved. Field activities include field-screening, soil excavation, backfilling with clean fill, and landfarming of excavated soil. Landfarming (rototilling, nutrient application) is estimated to take three years. |

Site Characterization Report Approved |
ADEC has reviewed the report titled, “2018 End-of-Season Karluk Landfarm Report (File # 2564.26.001)”for the Karluk School USTs 1-4 site in Karluk, Alaska, dated December 4, 2018. The Report was submitted via email on December 4, 2018 by Travis/Peterson Environmental Consulting, Inc. Fieldwork was conducted on August 10, 2018 and generally consisted of collecting soil samples for field-screening and laboratory analysis purposes, incorporating fertilizer into the soil following confirmation sample collection, and enclosing the soil with a high-visibility fence and signage. The objective of this field work was to remediate contaminated soil excavated from the site’s decommissioned underground storage tanks. |

The Report was submitted via email on October 29, 2019 by Travis/Peterson Environmental Consulting, Inc (TPECI). Fieldwork was conducted on September 19, 2019 and generally consisted of collecting soil samples for field-screening and laboratory analysis. Another round of soil characterization is expected in 2020. |

"2020 Landfarm end-of-season report for Karluk School USTs 1-4" received and under review. Comments on report issued to RP on 12/31/2020. Final report approval issued on 4/20/2021. The report discusses fieldwork conducted on 9/28/2020. Fieldwork consisted of field screening and the collection of five (plus one duplicate) laboratory samples from the landfarm. The results of the laboratory samples indicate that concentrations of diesel range organics (DRO) at the landfarm are decreasing. The report proposes to repurpose the landfarmed material at the Class III landfill in Karluk. ADEC CSP has no objection to this plan. The approval letter also discusses the Solid Waste Program (SWP) requirements for polluted soil disposal in a Class III landfill (the landfarm will need two RRO samples taken as RRO has not been sampled for at this site; the most recent GRO and DRO results can be used in the request to the SWP). |
