On this date, Shannon and Wilson excavated 3,445 cubic yards of petroleum impacted soil 12 to 13 feet bgs down to groundwater and transported it to a landfarm area. Confirmation soil samples collected at the groundwater interface contained DRO up to 14,000 mg/kg. The excavation was brought to grade with cleanfill. A school was built over the top of this former tank farm area. |

Meeting or Teleconference Held |
PM spoke with Tim McDermott [Facilities manager at Lake & Peninsula School District (LPSD)] and Dick Sharpe (Mayor of Chignik) about path to closure at Chignik School. Laura Hylton is LPSD's business manager and should be cc'd on future correspondence. The landfarmed soil was transferred near the landfill in 2002 (with ADEC authorization) where it currently remains. Tim and PM will meet in King Salmon in May/June 2013 timeframe and travel to Chignik to sample the stockpile. If the stockpile is clean, it may be spread over the landfill as cover if/after DEC's Solid Waste Program concurs. |

Site Visit |
DEC coordinated with the Lake and Peninsula School District (LPSD) and the Mayor of Chignik and conducted a site visit May 2013. During the site visit, DEC collected soil samples from: a test pit at the Chignik Bay City Tank Farm, a test pit at the Chignik Bay School Quonset Hut, and from the Chignik Bay School stockpile located at the dump. At the Chignik Bay City Tank Farm, soil samples collected at a depth of 1.5 and 3 feet bgs did not contain petroleum constituents above cleanup levels. At the Chignik Bay School Quonset Hut, two soil samples collected 2 feet bgs did not contain petroleum constituents above cleanup levels. At the stockpile, seven soil samples collected 2, 6, and 10 feet into the pile contained DRO up to 2,420 mg/kg. At 6 feet into the pile, strong hydrocarbon odors, stained soil, shotgun shells, and broken clay pigeons were noted. After sampling, the stockpile was spread from 20 feet to 10 feet above ground surface and amendments including fertilizer, nitrate, and sulfate were spread into the pile to promote remediation. |

Update or Other Action |
On this day, the LPSD provided a letter to the ADEC documenting the 1993 soil excavation beneath the Chignik Bay School. The letter (letter), dated December 1993, was prepared by Fred Brown of Shannon and Wilson, Inc (S&W). The letter stated that the LPSD contracted S&W to assist in the cleanup for this project; however, the LPSD did not authorize S&W to prepare a report. Instead, S&W provided analytical data and sampling information to the LPSD so that the LPSD could prepare a report internally. An internal report was never prepared. Analytical data indicate that DRO contaminated soil remains beneath the Chignik Bay School at concentrations above ADEC cleanup levels. Confirmation samples collected from the sidewalls of the excavation at 7 feet bgs contained DRO up to 31,000 mg/kg. Confirmation samples collected from the base of the excavation at 12 feet bgs contained DRO up to 22,000 mg/kg. Groundwater was encountered in the excavation at roughly 12 feet bgs. The assumed groundwater flow direction is to the north-northwest. The extent of contamination has not been defined at this site. |

The CSP received an email on this day from the LPSD. The LPSD indicated that the main source of drinking water is from surface water; however, groundwater wells also exist. The closest drinking water well to the school is located approximately "500' from the back of the school", and the Chignik Bay School reopened in September 2014 and is currently operating. |
