Update or Other Action |
Staff completed a site visit of Bullen Point and Point Lonely Distant Early Warning Sites in order to determine the condition of their dump sites and the erosion impacts. The dump sites at both places are on the lagoon-side of the facilities so are not experiencing the dramatic effects of erosion that have been seen at Oliktok or Barter Island. However, the face of the dumps are becoming exposed and there is debris in the adjacent surface water bodies. These sites will need to addressed during the Air Force’s Clean Sweep Operations. Another issue was identified at Point Lonely, though, that requires immediate attention. The ocean-side of the facility has lost over 150 feet of shoreline this summer. This has caused a pump house (deactivated) to collapse on to the beach. It appears there was a small fuel release when the building and pipes collapsed. PERP was on site and had the Air Force take samples to determine the extent. Additional actions will be taken upon receipt of the results. |

Contaminated Sites staff is working with the Air Force on creating a template for ecological and human health risk assessments covering six sites across the North Slope, including this site. The Air Force determined it needs to conduct base-line risk assessments at these sites prior to making cleanup decisions on them. Developing a template is an effort to make the process more efficient. |

Update or Other Action |
Staff reviewed the RI/FS for this site. PCBs were detected in 1 of 2 sediment samples. Selenium was detected in surface water at a concentration of 358 ug/L, above the screening criteria. It is unknown if the selenium is naturally occuring or anthropogenic. DRO was detected in landfill soils above Method One cleanup levels in 6 of 12 samples. RRO was detected above Method One cleanup levels in 4 of 12 samples. Stained gravels were seen in several test pits. The estimated size of the landfill is 27,000 square feet. The density and thickness of debris is variable. The average thickness is probably 3.5 ft. The estimated volume of the landfill is 3500 cu. yds, not including the cap. Erosion of the site is estimated to be lower than the average rates for Pt. Lonely due to the protective lagoon. |

Update or Other Action |
Contaminated Sites staff recently obtained term contractor review of a draft Air Force North Slope Risk Assessment Work Plan (RAWP). Comments were received from the term contractor, and a comment review teleconference was held with the term contractor risk assessor on 5/10/06. The RAWP seeks to develop risk based cleanup levels based on exposure pathways for categories of sites (e.g., garage sites) at Air Force radar stations in the north slope region. The work plan is generally well written, but some of the key items that need clarification are how data gaps will be handled at individual sites; determination of background levels for organics and inorganics; how it will be determined whether a large water body is potentially affected by a site; and how toxicity will be determined for trichloroethylene. |

Meeting or Teleconference Held |
Staff met with the Air Force to resolve comments on the 2005 RI/FS. It is thought that the cleanup of the landfill will result in decreased selenium concentrations in the adjacent lagoon. The thought is that the selenium may be natually occuring in the soil (although there is no background data), but the conditions in the landfill are anoxic resulting the the selenium going into solution. If the landfill is cleaned up, this will no longer occur. Long-term monitoring of the selenium after the landfill removal may be needed. |

Staff performed a site visit to Pt. Lonely with the North Slope Risk Assessment team. Sites SS03 and SS02 are included as template sites, but nearly all sites at Pt Lonely were visited. The former location of the pumphouse was identified and has not yet eroded into the ocean. The coast continues to erode, particularly in the vicinity of the former Sewage Outfall site and little beach remains for vehicle or foot travel on the beach in that area. |

Update or Other Action |
Contaminated Sites staff was informed by an Air Force contractor that Pacific Air Forces issued a policy regarding the cleanup of landfills. Apparently, only compliance funding (rather than the Defense Environmental Restoration Account) can be used for the cleanup of the landfills, even if hazardous substances are present in the landfill. Due to the lack of compliance funding, many landfills are not programmed for clean up until 2013 at the earliest, including the Point Lonely DEW Line landfill. However, the Air Force project manager for Oliktok believes compliance funds for removal of the Oliktok eroding landfill are secured and available for the 2007 performance-based contract cleanup. |

Meeting or Teleconference Held |
Contaminated Sites staff met with the Air Force and the Bureau of Land Management (BLM) to discuss the upcoming cleanup at Point Lonely Air Force Station. This site is located in a right-of-way on BLM property and the Air Force has to meet several environmental requirements before relinquishing the property. The Air Force requested to re-open a permitted landfill at Point Lonely for one time use to deposit demolition debris and low-level petroleum-contaminated soil. BLM is hesitant to approve it because landfills built on BLM property are not consistent with their policy. |

Risk Assessment Report Approved |
ADEC received the Final Risk Evaluation Report – Alaska North Slope Radar Installation Sites on November 6, 2007. This report meets the requirements of the ADEC Contaminated Sites Program Risk Assessment Procedures Manual, adopted by reference in 18 AAC 75.340. An approval letter was sent to Dave Cook, Program Manager HQ PACAF/A7NR, on December 10, 2007
This project identified categories of sites that are common on remote Air Force installations in the North Slope region of Alaska and developed conceptual site models and human health and ecological risk based screening levels for four of these categories: garage sites, fuel storage sites, non-fuel storage sites, and transformer sites. The project developed templates for conducting human health and ecological risk evaluations for these categories and performed a risk evaluation as a test case for one example of each type of site. The final report contains guidance on applying the process to other North Slope region sites. It may be used on a site-specific basis as a tool to assist in assessing potential risks posed by North Slope Air Force installation sites.

Draft Final LF007 Point Lonely CCR #1
ADEC does not accept the characterization that was completed for LF007 for use in determining what portions exceed the Method 1 cleanup levels.
There are two main concerns.
The response to the comment on the interpretation of the silica gel cleanup does not include any narrative explaining why the chromatograms show the presence of naturally occurring organics. The guidance requires this to support any contention that biogenic interference has elevated the sample results and that based on this they are not above cleanup levels. The InterpretationofChromatograms.pdf” is just a set of the chromatograms. The SGS case narratives say either “unknown hydrocarbon” or “middle distillate”. There is no evidence that a person with experience reviewing biogenic material in chromatograms looked at these and made a determination.
There has been no documentation that the MI samples were managed or prepared in accordance with the ADEC guidance. The 30 g aliquots were not collected by weight and there is no demonstration that any attempt to achieve uniformly sized aliquots. There is no demonstration that the samples were dried and sieved. One sample was reported at 27% solids which demonstrates that the samples were not dried.
This rejection of the characterization data requires a revision to the work plan submitted for the 2015 season.

In response to an emailed comment response a letter was sent that concluded: ADEC does not accept the characterization of LF007 as sufficient to determine locations where the cleanup levels have been met.
The DUs that were confirmed to be above the cleanup levels can be managed as contaminated soil for the 2015 field work. All other DUs are either to be resampled appropriately or managed as contaminated soil.
