Document, Report, or Work plan Review - other |
DEC received a Cleanup Report for the Eek LKSD Tank Farm dated April 2011. In March of 2011, Ridge Contracting (RCI), contractors for LKSD, removed 203 cubic yards of Petroleum-Oil-Lubricant (POL)-contaminated soil located at the former site of a 15,500-gallon above-ground heating oil storage tank (AST). The AST was situated adjacent to the LKSD School in Eek and supplied the school's heating system. Target COCs were identified in the CAP as Diesel and Residual Range Organics, and Polynuclear Aromatic Hydrocarbons. The DEC cleanup levels established for the site were the "Under 40 Inch Zone - Migration to Groundwater" levels. All but one confirmation sample collected from the excavation were below the 250 ppm DRO cleanup standard. All detected PAH analytes were below the most stringent cleanup level. One surface water sample was collected from the water that infiltrated the excavation. The water sample had DRO concentration of 3.68 mg/kg, TAH of 304.38 ug/L, and TAqH of 199.83 ug/L. |

Meeting or Teleconference Held |
Brunner spoke with James Mikesell, the regulatory compliance officer for the Lower Kuskokwim School District (LKSD), about two cleanup reports submitted for the Eek LKSD tank farm. The first report is dated April 2011, and the second is dated August 20, 2011. Brunner to send LKSD a letter describing the deficiencies in the two reports for LKSD to remedy. |

Document, Report, or Work plan Review - other |
Brunner received and reviewed the document entitled "Cleanup Report, Eek LKSD Tank Farm, Eek, Alaska" dated April 2011, and the letter report entitled "Eek Tank Farm Assessment and Cleanup" dated August 20, 2011. These two reports describe contaminated soil removal actions done at the Eek LKSD Tank Farm in March 2011 and May 2011. Letter sent to James Mikesell at LKSD on 04/30/2012 explaining that the two reports are approved, though the following deficiencies must be addressed by LKSD in their response:
1. Sampling of the surface waters nearest the tank farm for diesel-range organics, total aromatic hydrocarbons, and total aqueous hydrocarbons must be completed by LKSD to determine if the surface water exposure pathway is complete. The DEC-approved work plan by Travis Peterson Environmental Consulting, Inc. (TPECI) entitled "Eek School Tank Farm, Lower Kuskokwim School District, Corrective Action Plan" dated December 2010 describes the required sampling.
2. The LKSD did not contact DEC prior to completing the May 2011 soil removal action at the tank farm. The May 2011 excavation activities were not covered by the DEC-approved work plan by TPECI entitled "Eek School Tank Farm, Lower Kuskokwim School District, Corrective Action Plan" dated December 2010. An approved work plan was required by 18 AAC 75.335(b).
3. The excavation limits of the May 2011 soil removal area should have been sampled in accordance with DEC’s May 2010 Draft Field Sampling Guidance. The guidance is available on-line at: http://dec.alaska.gov/spar/csp/guidance/Draft%20Field%20Sampling%20Guidance.pdf. Since no samples were taken, there is no confirmation that all of the contaminated soil was removed.
4. DEC must be notified when there is an oil discharge to the land or water, per 18 AAC 75.300. DEC has no record of the diesel discharge that was excavated in May 2011 being reported as required.
5. The LKSD should have obtained DEC-approval before moving (off-site) or disposing of the soil from the March and May 2011 excavations, per 18 AAC 75.370(b).

Update or Other Action |
Letter received from Travis/Peterson Environmental Consulting, Inc. (TPECI) on behalf of the Lower Kuskowkim School District (LKSD) in response to ADEC's April 30, 2012 letter regarding the inadequacies of the cleanup done at the LKSD Eek School in 2011. The letter proposes confirmation samples be taken from the May 2011 excavation limits in accordance with ADEC's May 2010 Draft Field Sampling Guidance. |

Update or Other Action |
DEC issued a request in response to the letter dated May 7, 2012 from Travis/Peterson Environmental Consulting, Inc. (TPECI) submitted on behalf of the Lower Kuskowkim School District (LKSD). The request asks that: 1) LKSD provide a description of the location of surface water sampling done at the site in May 2011, and 2) LKSD submit a work plan revision describing how the horizontal and vertical limits of the May 2011 excavation will be located when confirmation samples are taken at the now backfilled hole. |

Update or Other Action |
DEC issued a request in response to the letter dated September 14, 2012 from Travis/Peterson Environmental Consulting, Inc. (TPECI) submitted on behalf of the Lower Kuskowkim School District (LKSD). The request asks that: 1) LKSD explain why the waterbody located 100 feet southeast of the site was not sampled for contaminants, and 2) LKSD submit a work plan revision within 60 days describing how the horizontal and vertical limits of the May 2011 excavation will be located when confirmation samples are taken at the now backfilled hole. The September 14, 2012 letter from TPECI proposed waiting to do the required confirmation sampling until a capital improvement project (CIP)next occurs in the area. Since there is no CIP work scheduled in the near future, the request to wait is unacceptable. |

Update or Other Action |
Sent letter to Lower Kuskokwim School District informing them of the list of schools in their district that are listed as contaminated sites, along with a priority ranking of each school with regard to risk to human health and the environment. The intent of the letter is to help the school district prioritize sites for remediation should funds become available. |

DEC reviewed and provided comments for the Contaminated Soil Management Plan, detailing preliminary plans for contaminated soil management during upcoming construction at the Eek K-12 School and at the former BIA school. |

Update or Other Action |
DEC reviewed, provided comments and approved the Environmental Management Plan for the upcoming excavation and construction activities at the Eek K-12 School Site. This plan provides procedures for managing potentially contaminated soil and ensuring worker safety during excavation and construction. The new school addition is to be constructed atop known areas of petroleum contamination associated with the Eek LKSD Tank Farm contaminated site. All excavated soils are to be segregated into lined stockpiles based on field screening results and dealt with accordingly. Note: this environmental management plan is not a site characterization plan as it does not meet the site characterization requirements for sampling frequency and delineation of contamination. |

Document, Report, or Work plan Review - other |
Review completed of Limited Action Removal Report for the Eek LKSD K-12 School site. This project included an addition/renovation of the existing school. Excavation took place in the known contaminated area, however this site has not been fully delineated so more contaminated soils were suspected. Soils were segregated into 'cold', 'warm', and 'hot' stockpiles. Five stockpiles were reused as backfill for the construction project/original excavation area. Three were used to construct a laydown pad area for staging equipment. Two were disposed of at the Eek Eastside Landfill. Approximately 2,560 cy of soils were reused at this site. 220 cy of contaminated soils were disposed of at the local landfill. Note, this site is still not fully characterized and a full delineation is still needed. |
