Underground Storage Tank Site Characterization or Assessment |
Three 4,000-gallon diesel UST's removed from the Akutan Power Plant. Removal of the tanks showed that the soil adjacent to the tanks is significantly contaminated with fuel. Standing water in the excavation has fuel floating on the surface. Strong diesel fuel odor. |

Update or Other Action |
Per Edward L. Hakala at EBSC Engineering, LLC, there was an investigation performed, a report prepared, and possibly submitted to ADEC. However, there is no record that can be found of the report. He asked for guidance on what to do next. ADEC advised him to obtain an environmental consultant to prepare a work plan to characterize the site.

Site Characterization Report Approved |
Sent responsible party approval letter for City of Akutan Power Plant Site Investigation, dated February, 2024. Analytical groundwater sample results detected DRO concentrations exceeding the ADEC cleanup limit of 1500 micrograms per liter (µg/L) in only one monitoring well (MW-01). Samples at MW-01 detected DRO concentration of 1740 µg/L and 2420 µg/L in the duplicate sample. DRO was the only analyte detected above cleanup limits. The remaining analytes sampled were either not detected or were detected at concentrations less than the applicable cleanup levels. A work plan was requested for further site investigation. |

Document, Report, or Work plan Review - other |
The Akutan Power Plant, Former Underground Storage Tank Location, Site Investigation Work Plan has been received and approved. The objective of the investigation effort is to characterize and define the extent of contamination in the groundwater at the former UST locations using three monitoring wells. Based on the products formerly stored at the site, the contaminants of concern (COCs) identified for the project consist of gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), volatile organic compounds (VOCs), and polycyclic aromatic hydrocarbons (PAHs). In addition, for monitoring wells in tidally influenced areas where the groundwater is hydrologically connected to the surface water, the analytical results will be compared to the DEC surface water criteria provided in Title 18 Alaska Administrative Code (AAC) 70 (ADEC, 2020). Based on the location of the site in relation to the ocean, total aromatic hydrocarbon and total aqueous hydrocarbon concentrations will be calculated using VOC (benzene, toluene, ethylbenzene, and total xylenes (BTEX) only) and PAH results.
