Potentially Responsible Party/State Interest Letter |
This letter included a request to ascertain the presence or absence of diesel in the gravel outside the utilidor or otherwise define the extent of contamination remaining according to an approved workplan. Also requested was that ADEC be notified as to BP's intentions in the matter before May 10th, 2014. |

Date of receipt of hardcopy (email copy received 7/25) document entitled BOC Bulk Fuel Facility Utilidor 2014 Site Assessment Work Plan. Activities planned include borehole sampling, well installation, well sampling, and surface water sampling. Meeting on June 26, 2014 included a brief presentation regarding activities planned for this site which at that time were to advance about 10 boreholes, install 4 wells, and sample 2 surface locations with additional visual inspection. Workplan generally follows those earlier stated goals. Seven boreholes will be advanced with 3 contingency boreholes which will be advanced, if the others suggest/indicate contamination present, in effort to delineate. Figure 2 shows intended sample locations. |

Date on Transmittal of the 2015 Contaminated Sites Water Quality Monitoring Workplan for D Pad, Service City, COTU North, COTU South, BOC Bulk Fuel Facility Utilidor, DSM Shop, PBOC Generator, MCC Fuel Island. As of 10/15/15 an approval letter hadn't been sent because ERM/BP had not yet provided the 2014 COTU South report although it has been reportedly just about ready for 2 months. |

Reviewed the BOC Bulk Fuel Facility Utilidor 2015 Contaminated Sites Monitoring Report, dated July 2016. Activities described in the report included collection of water samples from four pad-pore water monitoring wells (MW-01 through MW-04) and three surface water locations (SW-01 through SW-03). A well survey was also completed and showed groundwater moving generally west, towards surface water. Monitoring Well MW-01, which is the well nearest the former fuel island, exhibited concentrations of GRO at 13 mg/l, DRO at 12 mg/l, benzene at 0.39 mg/l, and TAH at 6.740 mg/l, all of which exceed the Alaska Water Quality Standards (AWQS) or the referenced Table C groundwater cleanup levels. None of the surface water samples exhibited contaminants exceeding the AWQS for TAH or TAqH.

Reviewed the 2016 Contaminated Sites Monitoring Report and 2017 Work Plan, dated April 7, 2017 for the BPX BOC Bulk Fuel Facility Utilidor site. The field effort was completed on August 17, 2016 and primarily consisted of collecting water samples from three surface water locations (SW01-14, SW02-14, and SW03-14) and four monitoring wells (MW01-14, MW02-14, MW03-14, and MW04-14). All water samples were submitted for one or more of the following laboratory analysis: gasoline range organics (GRO), diesel range organics (DRO), polycyclic aromatic hydrocarbons (PAHs), and/or benzene, toluene, ethylbenzene, and xylenes (BTEX).
None of the surface water sample results exceeded the Alaska Water Quality Standards (AWQS) for total aromatic hydrocarbons (TAH) or total aqueous hydrocarbons (TAqH). However Well (MW04-14), which is considered hydraulically connected to surface water, exhibited a concentration of benzene at 18 µg/l and total concentration of TAH at 28.78 µg/l, which exceeds the AWQS for TAH of 10 µg/l. The ADEC groundwater cleanup level (GCL) for benzene is 4.6 µg/l.
Samples collected from both Wells MW01-14 and MW03-14 exceeded ADEC GCLs for GRO, DRO, benzene, ethylbenzene, and total xylenes. The sample collected from Well MW02-14 did not exhibit contaminant concentrations above established GCLs.
Proposed activities outlined in the 2017 work plan generally include continuation of surface water and monitoring well sampling, however, only includes provisions to sample one surface water location (SW02-14).
ADEC requested a revised report/work plan be submitted by July 1, 2017, to included provisions for additional delineation.

Reviewed of the 2017 Contaminated Sites Monitoring Report and 2018 Work Plan, dated April 2018 for the BPX BOC Bulk Fuel Facility Utilidor site. The field effort was completed in late August 2017 and primarily consisted of collecting water samples from two surface water locations (SW02-14 and SW04-17) and four monitoring wells (MW01-14, MW02-14, MW03-14, and MW04-14). All water samples were submitted for one or more of the following laboratory analysis: gasoline range organics (GRO), diesel range organics (DRO), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and/or benzene, toluene, ethylbenzene, and xylenes (BTEX).
The Surface water sample location SW04-17 is a new location generally south and across a gravel road from Sample location SW02-14, and according to the report was completed instead of installing additional porewater monitoring wells to evaluate downgradient impacts. None of the surface water sample results exceeded the Alaska Water Quality Standards (AWQS) for total aromatic hydrocarbons (TAH) or total aqueous hydrocarbons (TAqH). However Well (MW04-14), which is considered hydraulically connected to surface water, exhibited a concentration of benzene at 41.9 µg/l, naphthalene at 1.7 µg/l, total concentration of TAH at 91.1 µg/l, and TAqH at 93.0 µg/l; all of which meet or exceed applicable standards. All other wells (MW01-14, MW02-14, and MW03-14) exceeded ADEC groundwater cleanup levels for GRO, DRO, benzene, and/or several over volatile constituents.
Recommendations (Section 6 – 2018 Work Plan) generally include continuation of surface water and monitoring well sampling in 2018. The work plan states “No additional monitoring wells or soil borings are proposed at this time, but will be considered following resampling of the newly established surface water sample south of the utilidor (SW04-17) in 2018 and verifying the presence or absence if LNAPL in existing monitoring wells.

Reviewed the 2018 Contaminated Sites Monitoring Report and 2019 Work Plan, dated July 18, 2019 for the BPX BOC Bulk Fuel Facility Utilidor site. The 2018 field effort primarily consisted of collecting water samples from two surface water locations (SW02-14 and SW04-17) and four monitoring wells (MW01-14, MW02-14, MW03-14, and MW04-14). All water samples were submitted for one or more of the following laboratory analysis: gasoline range organics (GRO), diesel range organics (DRO), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and/or benzene, toluene, ethylbenzene, and xylenes (BTEX).
None of the surface water sample results exceeded the Alaska Water Quality Standards (AWQS) for total aromatic hydrocarbons (TAH) or total aqueous hydrocarbons (TAqH). However, Well MW04-14, which is considered hydraulically connected to surface water, did exceed AWQS for TAH (91.1 µg/l) and TAqH (93.0 µg/l). Well MW01 -14 is historically the most contaminated well, with concentrations of GRO at 3,870 µg/l, DRO at 11,300 µg/l, benzene at 173 µg/l, toluene at 152 µg/l, ethylbenzene at 179 µg/l, and xylenes at 1,150 µg/l. Wells MW03-14 and MW02-14 both exceeded Table C GCLs for various other volatile constituents.
