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 |
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.

Cleanup Plan Approved |
Staff reviewed and approved the Draft Quality Assurance Program Plan for 2008 Clean Sweep Activities (Cleanup Plan) for USAF Point Lonely SRRS. This work plan describes the cleanup activities that will be conducted at the Point Lonely SRRS during 2008. Work specific to the Drum Storage site consists of excavation of petroleum contaminated soil with diesel range organics (DRO) and residual range organics (RRO) that exceeds arctic zone method one cleanup levels. Characterization of this site did not find DRO or RRO above the method two cleanup levels. Excavated soil will be landspread at the Diesel Spill site (SS005). |

CERCLA ROD Approved |
Decision document signed. Decision document was signed by Colonel Brent Johnson, USAF, on 8/27/2008 and by DEC Environmental Program Manager John Halverson on 8/29/2008. The main components of the remedy are excavation of DRO and RRO contaminated soil above the 18 AAC 75.341 method one arctic zone soil cleanup levels of 200 mg/kg and 2,000 mg/kg, respectively; treatment by landspreading of the excavated soil; verification that there is no surface staining at the landspread area and that landspread soil is not adversely impacting surface water. Method one cleanup level apply to this site because of its proximity to the ocean; rapid shoreline erosion makes this site vulnerable to near-future erosion and potential adverse impacts to water quality. |

| 8/29/2008 |
Cleanup Level(s) Approved |
Cleanup levels were approved with signing of the Decision Document on 8/29/2008. Cleanup levels are the Method One cleanup levels from 18 AAC 75.341 Table A2 for DRO and RRO and Method Two Arctic Zone cleanup levels from 18 AAC 75.341 Tables B1 and B2 for BTEX compounds, and PAHs. |
