Site Characterization Workplan Approved |
DEC reviewed and approved of Glogics "Workplan for Additional Site Characterization and
Interim Remedial Actions", dated May 15, 2012. This workplan presents the approach for the planned exploration work which is intended to provide further information regarding the nature and extent of soil and possible groundwater contamination at this site. This contamination predominantly was caused byfuel storage and handling practices at the fish-processing facility. In areas with obvious petroleum stains (e.g., fuel spills), interim-remedial actions also will be performed. |

Site Characterization Report Approved |
Staff reviewed Geologics "Report of Additional Site Characterization and Interim Remedial Actions, Snopac Dillingham Property, 3700 Yako Rd." This report documented the excavation and evaluation of multiple source areas at the facility. Contaminated soil left in place included former AST locations, a burn area, and stained areas. No groundwater contamination was noted. |

Meeting or Teleconference Held |
Meet with G-Logics (consultant for Snopac) and Shannon & Wilson (consultant for Icicle). G-Logics provided a draft Engineering Controls Plan earlier in the week to address potential controls with remaining contamination. The meeting was to provide G-Logics with feedback about the ECP. Icicle would like documentation that site closure with ICs can be granted if the engineering controls in the ECP are implemented.
Agreeded that if the facility is to be occupied before the engineering controls can be implemented, the burn area will be temporarily fenced off to reduce potential exposure by workers.
G-Logics will provide modified ECP for DEC review. |

Document, Report, or Work plan Review - other |
Received a letter from Icicle Seafoods documenting updates for four contaminated sites. The report stated that the river has encroached within the 5 foot perimeter of the soil cap on the old burn area. Icicle will have Shannon & Wilson develop a plan to develop a work plan to address these soils. |

Document, Report, or Work plan Review - other |
Shannon & Wilson submitted a work plan to address the dioxin contaminated soils at this site. The soils will be systematically sampled to identify areas with elevated dioxin levels. Areas identified with dioxin contamination exceeding ADEC method 2 cleanup levels will be removed. |

Update or Other Action |
At this time, the current project manager chooses to retain management of this site which has institutional controls. |

Update or Other Action |
Shannon & Wilson submitted an email providing preliminary results from their August sampling effort. The river has eroded the bank within the 5 foot perimeter of the dioxin contaminated burn area identified in the Institutional Controls developed for this site. Shannon & Wilson plans to mobilize to the site tomorrow to complete the 2016 work plan. Through consultation with Icicle and Shannon & Wilson it was agreed to remove and store in totes the soils identified above ADEC method 2 cleanup levels and then move and cover any remaining dioxin contaminated soils within 10 feet of the river bank erosion buffer to prevent any dioxin contaminated soils from eroding into the river. |

Document, Report, or Work plan Review - other |
Review of the 2016 Former Snopac Seafood Processing Facility, Limited Removal Action 3700 Yako Road, Dillingham, AK Report. Approximately 44 cy of soil were excavated from the capped former burn area and placed in 1 cy plastic lined cardboard boxes and stored out of the weather. Approximately 28 cy of the 44 cy total contained dioxin concentrations that exceed the most stringent ADEC Method Two cleanup level. The remaining 16 cy of soil contain detectable concentrations of dioxin, but at concentration less than the most stringent ADEC Method Two cleanup level. The soil remaining in the capped former burn area does not contain concentrations of dioxins exceeding the August 2016 ADEC-approved work plan action level of 47 ng/kg (the most stringent [former]ADEC Method Two cleanup level). ADEC revised the Method Two soil cleanup levels in November 2016. As a result, dioxin levels exceed the revised migration to groundwater cleanup level of 3.9 ng/kg in five of the remaining grids. Groundwater was not encountered during the 2016 limited removal action. Note that the remaining concentration in each of these grids is less than the revised human health levels for dermal contact, ingestion, and inhalation. |

Institutional Control Update |
Site evaluated for closure without Institutional Controls (ICs). When the site was closed with ICs back in 2014, contamination remained in three areas: A-3, S-9, and the Burn Area. Currently, contamination above cleanup levels has been fully removed at the Burn Area, however petroleum contamination remains at A-3 under a concrete pad and S-9 near utilities/piping. The site is ineligible for Cleanup Complete (without ICs) at this time. |

Institutional Control Update |
Addendum to the June 2, 2014 Cleanup Complete with ICs issued. This addendum documents that the Burn Area has been cleaned up to meet all cleanup levels and no further action is needed at the Burn Area. An update to the June 3, 2014 NEC was recorded which documents the removal of ICs from the Burn Area (ICs still remain at areas S-9 and AST-3). |
Kara Kusche |
| 10/8/2018 |
Update or Other Action |
ADEC approves the report titled "2018 Excavation Monitoring and Soil Sampling, Former AST A-3 Location" dated September 2018. This report documents excavation done in area A-3, and documents the sampling and disposal of soil stockpiles (via out of state landfill when contaminants were above lean up levels, and via land spreading when contaminants were below cleanup levels). The limits of excavation were not sampled because the goal of this work did not include removing all remaining soil contamination. |
