Update or Other Action |
Franklin Bluffs Camp Additional Assessment Activities Report submitted to ADEC. According to the report, although soils exceeding Method 2 cleanup levels were identified at SB11 in 1996 (3,600 ppm GRO), the additional investigation conducted in 2000 did not identify any soils exceeding Method 2 cleanup levels in this area. Soils may still exist on-site that exceed Method 2 cleanup levels at SB11. IT plans on removing the impacted soil above method 2 cleanup levels and request closure from ADEC. |

2000 Surface Water and Groundwater Monitoring Report, Franklin Bluffs Camp submitted to ADEC. The 2000 monitoring results indicate that concentrations of all contaminants of concern have generally remained stable or decreased and that all contaminant concentrations are below ADEC cleanup levels for the site. IT recommends discontinuing groundwater and surface water monitoring at the Franklin Bluffs Camp. |

Update or Other Action |
ADEC received the Corrective Action Report for the Alyeska Franklin Bluffs Camp. In August of 2001, Alyeska removed approximately 150 cubic yards of GRO and benzene contaminated soil. Past results had indicated GRO levels above the ADEC inhalation and ingestion cleanup levels. The excavation occurred 50 feet north of SB-11 which is located in the truck pull out area. Originally there was a small stain approximately four feet in diameter identified. There was no sheen on the adjacent surface water body. The final excavation reached a depth of 5.5 feet bgs. Excavation confirmation sample results less than Method 2 arctic zone cleanup levels. SLR recommended site closure. |

Received Trans Alaska Pipeline System: 2007 Monitoring Well Decommissioning Report. Four monitoring wells, MW-2 thru MW-5, were successfully located and decommissioned. MW-1, MW-6, and MW-7 were not located. MW-1 and MW-6 lie in a broad, open area and could not be located within a reasonable search time limit. MW-7 which lies near the Dalton Highway in a frequently used pull-out area could not be located using swingties nor metal locator and was assumed to be destroyed during road grading. |

Institutional Control Record Established |
There is contamination remaining above established cleanup levels at Alyeska Franklin Bluffs Camp but ADEC has determined there is no unacceptable risk to human health or the environment, and this site will be conditionally closed. This decision is subject to the following conditions: 1. A Notice of Environmental Contamination will be recorded on the ADEC database to document that there is residual contamination remaining on site above the most stringent ADEC cleanup levels; 2. Any proposal to transport soil off site requires ADEC approval in accordance with 18 AAC 75.370 (b).

Document, Report, or Work plan Review - other |
On this date, ADEC received the AEA Icewine #1 Cellar Stockpile Sampling and Characterization Report submitted by RSE and dated October 14, 2015. Soil was excavated for installation of an exploration well cellar. Reportedly, noticeable contamination was encountered at an unknown depth. Three soil samples collected from a 35 cy stockpile contained DRO at 372, 452, and 458 mg/kg. The soil stockpile was used to backfill the excavation after decommissioning of the exploration well. |

Document, Report, or Work plan Review - other |
On this date, received the AEA ICEWINE #2 Cellar Spoils Characterization Sampling Work Plan and Disposal dated March 19, 2017 and the Well Cellar & Conductor Casing Installation Report dated March 21, 2017 both submitted by RSE. All material was frozen solid during the well cellar excavation (it was around 0°F during this period). No gross contamination was encountered. A sample collected from cuttings at the pad/tundra interface during drilling for the conductor casing contained the highest PID screening result (295 ppm) and was sampled.Analytical results were: 376 mg/kg DRO; 18.2 mg/kg GRO; 0.008 mg/kg Benzene; 0.0208 mg/kg Toluene; 0.0906 Ethylbenzene;0.433 Xylenes; and 0.5524 Total BTEX. The next highest screening result was 85.4, also found in cuttings from the drilling the conductor casing, immediately below the pad/tundra interface. Following the work plan, all of this material – cuttings and spoils from the same location-- was used as backfill in the annular space between the cellar wall and excavation sidewall after the cellar was installed.

Institutional Control Compliance Review |
IC compliance review conducted. The site characterization and soil movement work conducted in 2017 was part of the original source area. The ICs are working so far and should be protective into the future. Because of recent activity and communication there is no need to send an IC compliance letter at this time. Schedule another review which includes a reminder letter in two years time. |
