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. There were two areas of contamination identified, the Module Train - Radome Area and the Module Train - Generator Area. At the Radome Area, PCBs exceeded 1 ppm in 4/17 samples, up to 34.6 ppm. At the generator area, DRO exceeded Method One cleanup levels in 5 of 5 samples collected, but did not exceed Method Two cleanup levels. Xylenes were also detected. The Air Force is recommending remedial action for the PCB contamination. |

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 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. |

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. |

CERCLA Remedial Action Completion Report |
Approval of Final Cleanup Report for 2008-2009 Clean Sweep Activities at Point Lonely Short Range Radar Station, Alaska (June 2010)
Module Train (SS012): The module train site consists of the gravel pad under and immediately surrounding the module train. PCB contaminated soil was excavated from two areas on both sides of the stairs leading to the generator room, and was transported off site for disposal. Confirmation sample results show that the site meets the cleanup level of 1 mg/kg for PCBs.
The report recommends no further action for PCB contaminated soil, and cleanup of soil impacted by a small oil spill from the generator room after the building is demolished. DEC concurs with this recommendation.

Cleanup Complete Determination Issued |
The Alaska Department of Environmental Conservation, Contaminated Sites Program (DEC) has completed a review of the environmental records associated with the Lonely AFS Dewline – Module Train (SS012) site at the U.S. Air Force Point Lonely Short Range Radar Station (SRRS), located in Point Lonely, Alaska. Based on the information provided to date, it has been determined that the contaminant concentrations remaining on-site do not pose an unacceptable risk to human health or the environment and no further remedial action will be required unless new information becomes available that indicates residual contaminants may pose an unacceptable risk.
This Cleanup Complete determination is based on the administrative record for the Lonely AFS Dewline – Module Train SS012, which is located in the DEC office in Fairbanks, Alaska. |
