4/18/1996 Proposed Plan The Corps finalized the proposed plan. Preferred alternatives included: Main Complex tank farm and USTs 5-1 and 5-2 - vapor extraction and air sparging; Maintence Bld, ACS MARS, Quonset Hut and Disposal Trench Area Burn Pit - soil excavation and off-site treatment followed by no further action; Operations Building - excavation and off-site treatment followed by natural attenuation and institutional controls; Landfill and Disposal Trenches - capping, natural attenuation (landfill area only) and institutional controls. John Halverson
6/3/1996 Update or Other Action Received a groundwater monitoring report for tank farm area from sampling in August 1995. It covered the main complex area tank farm and USTs (significant fuel contamination), ACS/MARS facility (low level DRO), Operations Building (DRO and low TEX), Landfill (low level VOCs) and Trench disposal areas (DRO and benzene at burn pit area). John Halverson
8/27/1996 Update or Other Action Received the December 1995 groundwater monitoring event report. It covers the tank farm area and former USTs at the main complex (significant petroleum contamination in GW at and downgradient from tank farm), the ACS MARS facility and Quonset Hut area (low level DRO in GW), the Operation Building (DRO and TEX in GW), Landfill (low level VOCs) and Trench Disposal Areas (DRO, benzene at burn pit area). John Halverson
11/22/1996 Interim Removal Action Approved Received final "Remedial Action Report Interim Removal Action, Wildwood AFS" by Harding and Lawson Assoc., October 28, 1996. Conclusions, based on confirmation samples at the end of the removal, include: ACS Mars - UST 250 and 253 meet cleanup levels, UST 251 did not (DRO 500 -3,400 mg/kg in soil); Quonset Hut Area - DRO 2,800 - 5,900 in soil; Trench Area Burn Pit - DRO 12,00 - 18,000 mg/kg; Main Complex - Building 55 and Drum Storage Area met cleanup levels; High Frequency Facility - up to 4,500 mg/kg DRO remains.

11/10/1999 Site Added to Database John Halverson
2/3/2005 Update or Other Action File number issued 2320.38.051 Aggie Blandford
6/2/2005 Site Characterization Workplan Approved A work plan for Site Characterization and Attenuation Monitoring was approved with minor comments. The work plan describes the planned investigation to delineate further the locations of remaining NAPL at the various source areas within the former Wildwood AFS using the Rapid Optical Screening Tool (ROST), Laser-Induced Fluorescence (LIF). It includes sampling and analysis to calibrate the results of the ROST LIF work and to further characterize contaminant nature and obtain data with which to evaluate the status of each source area using current Method II and III tools, and possibly a 4-phase partitioning model. Sampling and analysis will also obtain data with which to evaluate natural attenuation occurrence at each source area. Debra Caillouet
11/8/2005 GIS Position Updated Using Figure 2-3 from a Remedial Investigation Report Phase III Cleanup Design Wildwood Air Force Station, in conjunction with TopoZone Pro and the KPB Parcel Lookup, entered the coordinates for this site. Metadata includes No Topo Basemap, TopoZone Pro Street Maps, Black and White Aerial Photo, on a Medium Size Map, View Scale 1:10,000, Coordinate Datum NAD83. High degree of confidence in accuracy of location. Former Staff
6/15/2007 Update or Other Action The Declaration of Project Closure Decison for the CON/HTRW project at Wildwood was signed. Debra Caillouet
9/5/2007 Update or Other Action Staff reviewed and prepared comment on No DOD Action Indicated Report, Wildwood AFS, F10AK0251 HTRW Project 03, Draft July 07 The report summarizes the actions and data for twelve areas of concern at the former Wildwood Air Force station that are located at the High Frequency Facility, ACS MARS facility, Operations Building Facility, Rifle Range, Firing Range, Main Complex, and the Main Drum Storage Area. Comments on the draft document are being provided on the attached table. In general, DEC agrees with the conclusions to close these sites after the appropriate public comment period with the exception of the High Frequency Facility where the data supports a Conditional Closure. Debra Caillouet
9/5/2007 Site Characterization Report Approved The ROST/LIF Investigation, Former Wildwood Air Force Station, Revision 1, April 2007 Report was reviewed and approved. The report presents the results of the investigation at multiple areas within the former Wildwood AFS during the summer of 2005. The logs from the ROST/LIF are presented along with laboratory analysis results. The report provides valuable site characterization data to support future decisions and generally meets the requirements of 18 AAC 75.335 Site Characterization. Debra Caillouet

3/7/2008 Meeting or Teleconference Held Staff met with the USACE project manager and engineer to discuss comments on the draft proposed plan and incorporate them into the document. Debra Caillouet
4/21/2017 Document, Report, or Work plan Review - other Reviewed the Soil Removal and Confirmation Sampling Report, dated December 19, 2016 for the Wildwood AFS ACS MARS Facility. The described effort was completed on September 16, 2015. Activities generally consisted of test pitting, limited soil excavation at the Wildwood AFS ACS MARS Facility UST 250-1 site (Hazard ID 25206), and soil screening and analytical sampling. Several issues were identified in the report and ADEC requested a revised final report by July 1, 2017. Joshua Barsis
10/4/2017 Document, Report, or Work plan Review - other Reviewed the Revised Soil Removal and Confirmation Sampling Report, dated August 28, 2017 for the Wildwood AFS ACS MARS Facility. This submittal is the revised version to an earlier report, dated December 19, 2016. In addition, ADEC also reviewed the submitted response to ADEC comments document. Several issues were identified in the response. Please reference ADECs letter dated October 4, 2017 for additional information. Joshua Barsis
