Update or Other Action |
Community complaining of fuel odors inside the school building. Past boiler room fuel spills are on record with PERP. Spill response included excavation of contaminated soil from the southwest corner of the Alak High School building. Clean fill was used to replace soil excavated. Residents also concerned with apparent migration of contamination from a containment cell northeast of the school site underneath the school and through city drainage into a residential area south of the school. |

Site Assessment performed in 2002 by S&W. 27 analytical soil samples and 5 surface water samples were taken. DRO in the tank farm pad ranged from non-detect to 5,340 mg/kg. Benzene in the tank farm pad ranged from non-detect to 1.09 mg/kg. Surface water samples were not analyzed for TAH or TAqH. Surface water samples showed DRO up to 2.46 mg/kg; benzene was present but below ADEC cleanup levels. |

Update or Other Action |
Received interim corrective action report for field completed in October 2003. Approximately 700 cubic yards of diesel contaminated soil was removed. Two removal efforts were conducted one in August 2003 and the other in October 2003. Contamination remains at the limits of excavation up to 6,950 mg/kg DRO, which is below ADEC Method Two Arctic Zone cleanup levels, but above ADEC's most stringent cleanup levels. Benzene was not detected above ADEC cleanup levels. The west berm, former fuel transfer line, and northwest corner (associated with a potential BIA dump site) were left intact because of concerns with controlling interaction with surface waters. |

Update or Other Action |
North Slope Borough (NSB) submitted an Areawide Contaminated Sites Assessment complied by Shannon & Wilson sent to ADEC Spill Prevention and Response (John Dixon, Fairbanks). This document covers numerous NSB communities including Wainwright. The High School Tank Farm 360.38.003 is discussed. The report refers to a 70 gallon diesel spill in 2002 due to a valve failure in the boiler room. Their 2003 site visit revealed that upgrades were made to the day-tank in the boiler room to avoid any future spills and contaminated building materials had been removed and replaced. The report also mentions two spills in 1997, one 300 and one 400 gallon diesel spill. |

Reviewed Sewage Lagoon Contaminated Soil Stockpile report dated August 2011. The stockpile originated with the 2003 excavation of contaminated soil at the Alak School Tank Farm. The stockpile is approximately 4-6 feet thick and soil samples were collected from various intervals from 0.5-3 feet below the surface. Sample results generally indicate that the deeper soil has higher DRO concentrations than the shallower soil, with DRO detected at a maximum of 2,130 mg/kg at 1.5 feet bgs. Samples collected from approximately 0.5 feet bgs contained DRO up to 177 mg/kg. |

Date of document entitled Wainwright Alak School Former Tank Farm, Draft Site Characterization Work Plan. This effort will begin late April with the advancement of 10 soil borings. Two samples per boring will be collected and analyzed for GRO/DRO/RRO/VOCs and 10 percent PAHs. Up to five of these borings will be completed as monitoring wells. Groundwater, surface water, and sediment will be sampled later in the season. |

Site Characterization Workplan Approved |
Date of receipt of Wainwright Alak School Former Tank Farm,Site Characterization Work Plan- Final. ADEC approved the March 31, 2015 version with a comment acknowledging that lead would be added to the analytical suite in a letter dated April 6, 2015. Lead is not in the final workplan delivered. |

Document, Report, or Work plan Review - other |
Reviewed the Site Characterization Report, dated May 13, 2016 for the NSB Wainwright Alak School Former Tank Farm site. The objecting of this work was to determine if contaminated soil was effectively removed during previous field efforts and evaluate potential offsite migration of contamination. Actives completed during the 2015 field effort consisted of advancing 10 soil borings, 5 of which were completed as monitoring wells, and collecting soil and water samples as appropriate. Three surface water samples and one sediment sample were also collected.
Analytical results revealed that diesel range organics (DRO) was present at 33,100 mg/kg in one soil sample (SB-04) collected from about 4 feet below surface grade, which exceeds the ADEC Method Two Arctic Zone Cleanup Level of 12,500 mg/kg. Additionally, benzene was present in one of the monitoring wells placed northwest of the site, across Main Street (MW-05) up at 0.185 mg/l.
Recommendations in the report included completing two additional groundwater monitoring events at MW-01, MW0-03, and MW-05 in 2016 and 2017; and backfilling selected ponded areas to mitigate sediment exposure pathways.
ADEC approved the report via letter on June 14, 2016 and concurred with the report recommendations; however, also requested that the area surrounding Sample SB-04 be capped and brought to grade. Work plan was requested by July 20, 2016.

Reviewed the NSB Wainwright Alak School Former Tank Farm Site Characterization Report Addendum, dated March 30, 2017 for the NSB Wainwright Alak School Former Tank Farm site. Activities completed during the 2016 field season included backfilling low-lying ponded areas and capping the area where Soil Boring SB-04 was taken, and collecting porewater samples from Monitoring Wells MW-01, MW-03, and MW-05. Additional sampling and/or backfilling is planned for the 2017 season. |

Site Visit |
ADEC performed an inspected of this site on August 15, 2017 and noted light sheening in various small water bodies in the vicinity of this site. A light sheen was observed in various small water bodies at this site and across Main Street. It is not clear if the sheening was biogenic or petroleum related. DEC requested further evaluation and sampling be included in the 2018 monitoring activities to determine the nature of the sheens. A work plan was requested by January 1, 2018. |

Reviewed the 2018 Groundwater Monitoring Work Plan, dated April 10, 2018 for the NSB Wainwright Alak School Former Tank Farm site. Proposed activities include collecting porewater samples from three monitoring wells (MW-01, MW-03, and MW-05). Sampled analysis will include diesel range organics (DRO), residual range organics (RRO), benzene, toluene, ethylbenzene, and xylenes (BTEX), and polycyclic aromatic hydrocarbons (PAHs). The plan in and of itself does not address all of the issues outlined in former letters (October 2, 2017 and November 20, 2017). Additionally, ADEC has not received the revised version of the NSB Wainwright Alak School Former Tank Farm Site Characterization Report Addendum, dated March 30, 2017; as requested in the June 29, 2017 letter. |

Division of Spill Prevention and Response personnel (L. Krebs-Barsis, S. Joyce) travelled to Wainwright with North Slope Borough personnel (C. Trapp) for a Compliance Order By Consent inspections. The lot was vacant. No Article 3 cleanup waste was observed. No petroleum sheen was observed in the surface water on site. Posts for the old structure were still present, teacher housing is directly adjacent. |
