2/6/2003 Site Number Identifier Changed Changed the Region from 36 to 31. Former Staff
1/14/2005 Update or Other Action Staff approved a workplan for soil sampling at the Point Lonely Long Range Radar Station during the demolition and removal of beach fuel tanks, pump house, tank berm, and associated fuel lines. (Youcha). Emily Youcha
6/2/2005 Site Ranked Using the AHRM Initial site ranking. Emily Youcha
6/2/2005 Site Characterization Workplan Approved Staff approved a remedial investigation/feasibility study workplan for the site. Samples will be collected for DRO/GRO/RRO, BTEX, VOCs, and PAHs. Emily Youcha
7/25/2005 Update or Other Action Staff attended a site visit to Pt Lonely AFS on July 18 with BLM representatives. Emily Youcha
7/29/2005 Meeting or Teleconference Held 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. Emily Youcha
12/8/2005 Meeting or Teleconference Held Staff attended the Restoration Advisory Board meeting in Barrow and provided a summary of the current activites at the site. Emily Youcha
3/21/2006 Update or Other Action Staff received a copy of the 2005 draft RI/FS. Staff participated in a meeting with the BLM and the Air Force on February 17 to discuss the status of Pt. Lonely and a potential transfer of the Air Force Buildings to the North Slope Borough. Emily Youcha
5/15/2006 Update or Other Action Staff reviewed the RI/FS for SS04 POL Storage area. VOC contamination was identified in a puddle off the pad during the 1993 RI. In 2005, samples were again collected from this small, isolated surface-water body and 1,1-DCE, benzene, cis 1,2,-DCE, PCE, TCE, TAH, and TAqH all exceeded the water quality standards 18 AAC 70. DEC requested additional characterization of the upgradient pore water and the location of the source be identified. Emily Youcha
5/26/2006 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. Emily Youcha
6/1/2006 Meeting or Teleconference Held Staff attended a comment resolution meeting for the 2005 RI/FS. The Air Force will conduct a treatability study at this site. They will pump the water out of the pond (puddle) and wait for it to recharge. THen they will collect samples to see if the water is contaminated. They will repeat this process and monitor to see if contaminated water recharges the puddle. The purpose is to see whether there is a remaining source of contamination in the pore water because VOC contamination was not detected in the upgradient soil. Another objective is to remove contaminated water from the puddle. Emily Youcha
7/11/2006 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. Emily Youcha
8/3/2006 Update or Other Action Staff received a workplan to install 5 wellpoints surrounding the VOC-contaminated "puddle". 5 samples will be analyzed for VOCs in the pore water and 1 sample will be collected in the surface water. Addtionally, after initial sampling, the consultant will pump water out of the puddle and collect samples from the well points and water to see if the recharge water is contaminated. Emily Youcha
8/18/2006 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. Emily Youcha

12/11/2007 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. Tamar Stephens
