On this date, ADEC received the Port of Anchorage ABI Cement Terminal Report dated November 3, 1993 and submitted by Hart Crowser. In September 1993, the three soil borings MW-1, MW-2, and MW-3 were advanced on property and completed as monitoring wells linearly along the railroad tracks to determine if there was migration of contaminants from offsite sources. Two soil samples were collected per borehole. A soil sample collected at a depth of 15 to 17 feet bgs from MW-1 located on the south end of the property contained benzene at 1.0 mg/kg, VPH at 280 mg/kg, and EPH at 1,700 mg/kg. A soil samples collected at a depth of 20 to 21.5 feet bgs mg/kg from MW-1 contained benzene at 0.35 mg/kg, VPH at 89 mg/kg, and EPH at 590 mg/kg. MW-2 and MW-3 did not contain contaminants above cleanup levels with the exception of one soil sample collected from MW-3 at a depth of 7.9 to 9 feet bgs which contained benzene at 0.09 mg/kg. All of the monitoring wells groundwater contained petroleum constituents above Table C Groundwater Cleanup levels with MW-1 containing the most significant contamination. MW-1 contained benzene at 3.40 mg/L, VPH at 7.6 mg/L, and EPH at 75 mg/L. Groundwater was observed at 5 feet bgs. |

Site Visit |
On this date, ADEC performed a site recon to locate the permanent monitoring wells MW-1, MW-2, and MW-3, which were installed September 1993. MW-2 was the only monitoring well located and pictures were taken. It is possible recent gravel fill for the parking lot may have covered MW-1. However, the ultimate fate of MW-1 and MW-3 is unknown. |

Offsite Soil or Groundwater Disposal Approved |
On this date, ADEC approved the transport of petroleum impacted soil from the water line project to the Anchorage Regional Landfill. Only one of the composite soil samples collected from the piles contained DRO above ADEC method two migration to groundwater cleanup levels with DRO at 502 mg/kg.

Document, Report, or Work plan Review - other |
On this date, ADEC received the ABI Cement Loading Facility Water Line Extension Project Soil Characterization and Disposal Report: Portion of USSS 1170 Alaska Railroad Terminal Reserve (ARRC Lease Lot A3) submitted by RSE and dated January 13, 2016. The ABI water line project involved installation of 530 linear feet of water line at a depth of 10 feet bgs. Soil was characterized as it was excavated from the water line trench. Soil samples collected along the pipeline locations at 4 feet bgs contained DRO up to 1,020; 1,2,4-trimethylbenzene up to 29.0 mg/kg; benzene at 0.659 mg/kg; and the PAH 2-methylnapthalene at 11.6 mg/kg. Soil not suitable for reuse as back fill was segregated into four stockpiles. The 800 cy stockpile 1 was transported to ARL 12/12/15. The 300 cy stockpile 2 is currently staged at ASR to be transferred to ARL Spring 2016. The 800 cy assumed dirty stockpile 3 and the 700 cy assumed clean stockpile 4 are stored at the abi facility pending characterization to be transported to the appropriate facility. |

Document, Report, or Work plan Review - other |
Reviewed and approved Environmental Sampling Plan for the Petroleum Cement Terminal. Soil and groundwater samples will be collected along the planned route of utilities from the ABI Cement Dome property, along the shore with Cook Inlet to POA property to evaluate for the presence of contaminants. Data will be used to inform the handling of soil and water and evaluate worker safety during execution of the utility project(reference 2100.38.535 MOA Port of Anchorage). |

Soil samples collected 7 to 10 feet bgs were above cleanup levels from the four test borings 05, 06, and 07( located downgradient of the 2100.38.311 Tesoro #1 Port of Anchorage site and the delta western tank farm) and 11 (located upgradient of the ABI cement dome) with GRO up to 629 mg/kg, DRO up to 6,640 mg/kg, 1,2,4-trimethylbenzene up to 43.5 mg/kg, 1,3,5-trimethylbenzene up to 17.9 mg/kg, benzene up to 0.416 mg/kg, ethylbenzene up to 11.9 mg/kg, naphthalene up to 4.34 mg/kg and xylenes up to 54.5 mg/kg. Additionally, a slight fuel odor was noted from test boring 11 at 8 to 10 feet bgs Groundwater was encountered 2 to 15 feet bgs and was noted to be highly tidally influenced. Five temporary well points were advanced. Two of these temporary wells, TW-03 and TW-04 located downgradient of the 2100.38.311 Tesoro #1 Port of Anchorage site and the delta western tank farm) contained contaminant concentrations above cleanup levels with DRO up to 87.9 mg/L, RRO up to 1.74 mg/L, benzene up to 15.2 ug/L, ethylbenzene up to 15.8 ug/L, naphthalene up to 1.74 ug/L, and 1-methylnapthalene up to 26.9 ug/L. |

On this date, ADEC received the Port of Anchorage Modernization Program Petroleum and Cement Terminal Environmental Characterization Report: Waterline Realignment Addendum submitted by R&M and dated November 6, 2018. The purpose of this addendum was to investigate the potential location of a buried World War II Landing Ship-Tank (LST) to support route selection for waterline installation as part of the proposed Petroleum and Cement Terminal (PCT) Project. Three soil borings were advanced 2 to 12 feet bgs adjacent to the ABI cement dome. Only testpit RM18-TH01 located west of the ABI cement dome contained contaminant concentrations above cleanup levels with EDB up to 0.000378J mg/kg. |

Document, Report, or Work plan Review - other |
DEC received the Soil and Groundwater Management Report - Port of Alaska Modernization Program (2021 to 2022), dated December 2022. 1,309 cubic yards of obviously contaminated soil was treated at ASR and 4,448 cubic yards from stockpiles were sent to the Anchorage landfill. Dewatering occurred from the fuel line excavation and during installation of electrical and water lines near the ABI cement dome. Wastewater was discharged to the AWWU sewer system. Samples collected from the stockpiles contained some petroleum compounds above DEC cleanup levels. Four piles (02, 08, 10, and 11) contained some solvents, including 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane, 1,2-dichloropropane, 1,2,3-trichloropropane, and 1,2-dibromoethane. These piles were excavated from the southern portion of the project area south of ABI Cement Dome. |
