Site Visit |
One day trip to meet with owner Layne Parker and consultant Elijah Donat to work out details of additional characterization sampling and contaminated soil removal work plan for the filling station. Water wells at locations on properties nearby the station in all directions were identified and visited to obtain permission to collect analytical samples. Some uncertainty remains despite the Phase I and Phase II Site Characterization of soil and groundwater. |

Document, Report, or Work plan Review - other |
DEC evaluated and approved the Gustavus Dray Filling Station Interim Cleanup Report submitted by Chilkat Environmental Inc. The Report summarized cleanup actions taken to date and set up a plan to remediate the soil stockpile with spring and fall reports to DEC, maintenance of ORC in the on-Site wells, annual sampling of the on-site well, install a new tank farm, and when available excavate the old tank farm and remediate the soil at the soil stockpile site. |

Update or Other Action |
Chilkat Environmental Inc. (Chilkat) submitted a memo update to inform DEC of site activity at the Gustavus Dray planned in accordance with the DEC approved 2016 Cleanup Report with a two year corrective action plan. Stockpile sampling to remove a lift for land spreading will be performed on the contaminated soil. If any of the composite samples are above 1.5ppm SPLP, no lift will be performed. Results of the stockpile sampling will be submitted with a Laboratory Data Checklist, and a narrative and photos to document the results will submitted in 2017.
Other corrective actions scheduled to occur by August 2018, include additional stockpile management, construction of a new tank farm and completing removal of contaminated soil from beneath the old tank farm site. Once constructed, Chilkat will manage contaminated soil that may be encountered when installing new tank supply lines from the new tank farm to the dispenser island. Documentation will follow in November 2018 from Chilkat.

Document, Report, or Work plan Review - other |
3 composite soil samples were collected from 2 feet above berm within the contaminated soil stockpile. These were sent to Friedman & Bruya Inc. for synthetic precipitation leaching procedure (SPLP) for gasoline range organics (GRO). The results were less than 500 µg/L thus the soil sampled is acceptable for lift and subsequent land spreading on site. The responsible party is currently working on replacing the tanks and a cleanup will follow. |

Update or Other Action |
Spoke to Elijah Donat and the second round of excavation will be underway soon. I requested that for the sump location, the analyses required are PAHs, BTEX, DRO, GRO, RRO, and VOCs. Please have the drinking water wells at the Gustavus Dray and the Sunnyside Market sampled and analyzed for GRO, BTEX, DRO, VOCs, and PAHs. |

Update or Other Action |
According to Chilkat Environmental, the excavation of the former AST area is complete and 300 cubic yards was removed. The tank farm drain was clean but found chunks of drums and absorbents. Twenty cubic yards was excavated form this area and the full suite of analytes will be analyzed. The source now has been excavated. The Dray well was also sampled. At the dispenser island, it is suspected that people pour old fuel down the drain. The closest monitoring well had about 1 mm of product on it and the water was black and slimy. The drain at the island is connected to a drain in the shop which was concreted (need verification). The second drain went to a vault/concrete box with an earth floor, then 50 ft. to where the tank farm was and drained to just outside the tank farm berm and liner. |

Site Characterization Workplan Approved |
Approved the Chilkat Environmental work plan to advance test pits to the groundwater interface at about seven feet belowground. The investigation will begin at the release location and move south. Soil samples will be collected from the groundwater interface and field screened using a photoionization detector (PID). Ten to 20 soil samples will be collected and analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX). |

Update or Other Action |
Approved the excavation, stockpiling, and later screening of soil to a depth of 2 ft. to accommodate the construction of the new containment. This soil is overburden and is most likely uncontaminated. |
Danielle Duncan |

Update or Other Action |
The Sunnyside Market drinking water well was sampled by Chilkat Environmental for gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), volatile organic compounds (VOCs), and semi-volatile organics (SVOCs). No contaminants were detected. |

Site Characterization Report Approved |
Approved the Gustavus Dray Filling Station Interim Cleanup Report 2018 & Groundwater interface sampling this date. The groundwater contamination plume requires delineation. The Gustavus Dray and Sunnyside Cafe wells were sampled and analyzed for VOCs, SVOCs, GRO, DRO, and RRO. Although the majority of the analytical results for the wells were non-detect and met ADEC groundwater cleanup levels in 18 AAC 75.345, there were naphthalenes present at 0.023 to 0.040 µg/L in the Gustavus Dray well, however these data may not be accurate because these compounds were also detected in the laboratory method blank. A new tank farm and dispenser island are being built and more contaminated soil will be excavated.

Site Characterization Report Approved |
The ADEC approved the "2022 site characterization report" this date. The report details the installation of 3 new monitoring wells (MW7-9) to the southwest of the site. The monitoring wells were purged and sampled for GRO, DRO, RRO, VOCs and SVOCs. MW-8 had an exceedance for GRO, ethylbenzene, and naphthalene. MW-7 had an exceedance for naphthalene, and MW-9 was non detect. All drinking water wells were non detect. The ADEC concurred with the reports conclusions that additional groundwater monitoring was necessary. |

Site Characterization Report Approved |
The ADEC received the “2023 Monitoring Well Report”, dated August 11, 2023. A revised “2023 Monitoring Well Report” dated December 19, 2023, was received via email. The revised report is approved. The report generally describes the field activities that took place on July 18, 2023. All monitoring wells were purged using a disposable bailer. Groundwater samples were analyzed for Gasoline Range Organics (GRO), Diesel Range Organics (DRO), Residual Range Organics (RRO), Volatile organic compounds (VOCs), and Semi-volatile organic compounds (SVOCs). A duplicate sample was collected from MW-8 and was not submitted blind to the laboratory. Groundwater samples from monitoring well (MW-7) exceeded the ADEC groundwater cleanup levels for GRO (2,350 µg/L; doubled in concentration from results in 2022), Ethylbenzene (30.7 µg/L), and Naphthalene (20.8 µg/L). Groundwater samples from monitoring well (MW-8) exceeded the ADEC groundwater cleanup levels for GRO (3,630 µg/L), DRO (1,780 µg/L), and Naphthalene (15.3 µg/L); additionally, its duplicate exceeded for 1,3,5-Trimethylbenzene (173 µg/L). Groundwater samples from monitoring well (MW-9) resulted in concentrations below ADEC groundwater cleanup levels and/or no detections for two consecutive sampling events. |
