Site Characterization Report Approved |
Staff reviewed a draft after-action report for a pipeline investigation associated with the 1.5-million gallon UST. The report had extensive deficiencies including no chemical quality assurance data, no screening data for soil samples and no soil characterization. Staff requested a rewrite from the COE. Presented data showed 29 soil samples of 64 over 100 mg/kg DRO with a high of 12,500 mg/kg below the pipelines. |

Site Characterization Workplan Approved |
Staff reviewed a site characterization report for an utilidor removal for the former power plant FUDS in Whittier. Soil and groundwater contamination was present at levels over method two. Fingerprinting identified the primary contaminant as weathered No. 6 fuel oil which was the fuel stored in the former 1.5 million gallon UST decommissioned in 1998. The utilidor contained several hundred feet of asbestos insulated pipe that had deteriorated and mixed with soil. The approximately 300-tons of material was packaged as an asbestos waste stream and disposed off-site at Rabanco Regional Landfill in Washington. The concrete utilidor was cleaned and left in-place. Further characterization will likely be necessary to characterize the lateral extent of soil and groundwater impacts |

Meeting or Teleconference Held |
Staff participated in a site inspection and meeting with the COE and Alaska Railroad in Whittier at the former 1.5 million gallon Underground Storage Tank Formerly Used Defense Site. The main topic of discussion was well placement to determine if site groundwater impacts are migrating to the marine environment. There are several site restrictions due to a rail track and a barge company operation. The COE proposed installing several temporary wells with push equipment to avoid having well hardware in an industrial area. We discussed that the wells may have to be advanced three or four times to establish a trend and to reflect any seasonal changes. Staff also met with a leaseholder on city property who is interested in purchasing contaminated property. We discussed the status of a DEC Brownfield grant to provide additional characterization data |

Update or Other Action |
CS staff review and commented on a draft workplan for monitoring well installation for the Power Plant FUDS in Whittier. Impacts from a former 1.5-million gallon UST have been noted in soil and groundwater in the vicinity of the old tank and pipeline utilidor. The wells to be installed will be ten temporary wells between the impacted site and Passage Canal to assess contaminant transport to the marine environment |

Site Characterization Report Approved |
Contaminated Sites staff reviewed a groundwater investigation report for the Whittier Power Plant FUDS in Whittier. Ten well installations were attempted with a goeprobe rig with one well successfully installed. The others were stopped by bedrock or heavy shot rock prior to contacting the water table. The one successful well and three existing wells were sampled and found to be below Chapter 75 Table C values for petroleum. Groundwater results from an investigation in 2004 showed level of DRO well over saturation. It is surmised that intrusive earthwork the week before groundwater sampling may have mobilized contamination and caused artificially elevated results. More sampling rounds are planned to establish trend data |

Meeting or Teleconference Held |
Contaminated Sites staff participated in a comment resolution meeting for Remedial Investigations at two Formerly Used Defense Sites in Whittier. The Former Military Power Plant and the Boat Harbor are both proposed for Method 2 ingestion for primarily DRO in soil. Institutional controls will be established at both sites for possible future soil management and Monitored Natural Attenuation will be the preferred remedy at the Boat Harbor as there are residual soil impacts over ingestion levels |

Site Characterization Report Approved |
Contaminated sites staff reviewed and commented on Remedial Investigation reports for two FUDS in Whittier. The Former Military Power Plant was associated with a 1.5 million-gallon underground storage tank, pump house and pipelines. Remedial actions over the years have removed the tank, and impacted soil associated with the pump house and pipelines. The Corps of Engineers is proposing alternative cleanup levels for benzene, Diesel and Residual Range Organics based on elimination of the migration to ground water pathway. The Boat Harbor FUDS in Whittier is proposed for Monitored Natural Attenuation and Institutional Controls. Residual impacts in soil are over ingestion levels in places, but the migration pathways are minimal if long term monitoring shows that contaminants aren’t leaching into the groundwater |

Meeting or Teleconference Held |
Contaminated Sites staff participated in a public meeting in Whittier with the Corps of engineers. Turnout was fairly good. The COE introduced Proposed Plans for two Formerly Used Defense Sites, the Former Military Power Plant and the Boat Harbor. The Power Plant had a 1.4-million gallon UST, three pipelines and a vault pump house associated with the site. The Boat Harbor was the site of a former military tank farm that spilled about 5-million gallons of mostly diesel fuel during the March 1964 earthquake. The Power Plant site has had a couple remedial actions over the years and has been cleaned up to an upper confidence limit of about 600 mg/kg DRO. This site is proposed for Cleanup Complete with Institutional Controls. The Boat Harbor site has residual contamination well over the proposed Method Two Ingestion cleanup levels, so will have to proceed to long term monitoring to demonstrate if contaminants are dissolving into the groundwater and migrating to the marine environment. Both sites have proposed eliminating the migration to groundwater pathway due to being adjacent to the ocean, shallow bedrock, no wells in the vicinity, and the city of Whittier has an established water supply to the areas |

Update or Other Action |
Contaminated Sites staff reviewed draft decision documents for two FUDS in Whittier Alaska. The Small Boat Harbor has residual DRO contamination in soil from above ground storage tank failures caused by the 1964 earthquake. The preferred remedy is Monitored Natural Attenuation with Institutional Controls. Groundwater will be monitored to confirm attenuation trends and ensure contaminant migration to the marine environment is not exceeding ecological screening levels. The Former Power Plant has residual DRO contamination over cleanup levels. The preferred remedy is Institutional Controls for future soil management. Both sites are using Ingestion cleanup levels as area groundwater is not considered a drinking water source |

Update or Other Action |
DEC signed the Port of Whittier Military Reservation Containerized HTRW Project Closeout Report, dated Sept. 22, 2009. The report documents that the Corps of Engineers has removed or emptied all known FUDS Program eligible containerized waste (drums, tanks, pipelines) from the property. No further CON/HTRW work is necessary. This decision may be reviewed and modified if new information indicates addtional containerized waste from past military activities is present.
An HTRW project addressing contaminated soil/groundwater remains open. |

Cleanup Complete Determination Issued |
CS staff reviewed and approved a Declaration of Project Closure Decision for the FUDS HTRW Project Power Plant Contaminated Soils Port of Whittier Military Reservation. Previous investigations and removal actions determined that no further remedial action was necessary at the site. Institutional controls (notice to the State Land Recorder’s Office) were implemented to inform landowners the petroleum compounds remain in soil at concentrations above the State of Alaska soil cleanup level for the migration to groundwater pathway. Reasonable Maximum Exposure concentrations were calculated for benzo(a)pyrene, DRO and RRO with results of 0.9 mg/Kg, 600 mg/Kg and 1,760 mg/Kg respectively. The RME conc.'s are below the ingestion and inhalation cleanup levels for each compound. The approved May, 2011 Decision identified no further remedial action with Institutional Controls (implemented in 2010) as the selected remedy for the site. The No Department of Defense Action Indicated Report supports the conclusion that all hazardous and toxic waste concerns have been addressed and no further HTRW actions are required for this project. |
