Problems/Comments
Last staff assigned was Howard.ST77 located near former Building 32-127 on Acacia Drive. Two USTs (321 and 322) located by this building. Both tanks had 2500-gallon capacity. One held gasoline, one held JP-8. Tanks had reportedly been in use for 15 years at time of closure (August 1993). Site entered by Shannon & Wilson
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 1/1/1995 | Document, Report, or Work plan Review - other | ADEC letter to Dept. Of Air Force (J. Williamson and C. Mayer) from J. Halverson RE: SERA Phase III Site Assessment Work Plans, Preliminary Draft Dec. 1994. Figure 2.3-2-The figure is not consistent with the site map from the underground storage tank (UST) closure site assessment report, which shows the former tanks on the south side of the road. The actual location of the former system needs to be verified by the Air Force. Soil borings should be placed in the immediate vicinity of the former USTs and along the vent line piping. | Louis Howard |
| 3/15/1995 | Document, Report, or Work plan Review - other | ADEC (J. Halverson) sent the Dept. Of Air Force (J. Williamson & C. Mayer 3 SUG/CEVR) a letter RE: SERA Phase III Site Assessment Work Plans, Draft February 1995. Section 2.1.4-The last paragraph states: "It is expected that the 300 gallon spill will be included as part of this investigation." However, no details are provided on how this will be done. The location of the recent release should be identified on the site diagram along with proposed soil boring and monitoring well locations. Details on proposed sampling and analysis associated with the recent release should be included in the plan. During the 1994, UST #150 was removed from the northwest side of building 32-127 (NEW Bldg. # is 8326 on Fighter Drive-AGE Storage Facility Shop). Petroleum contaminated soil was identified. In the process of attempting to install a new UST, test pits were dug and additional areas of contaminated soil were located along with an old wooden septic crib. The location of these impacted areas should be shown on the site diagram. Since this area is immediately upgradient of the USTs #321 and 322, which is being investigated during this phase of the work, the department stroungly recommends this site investigation/remedial design be expanded to include both of these areas. ADEC understands this work would need to be coordinated with the Compliance Section staff. Figure 2.3-2: One of the soil borings and possibly a monitoring well should be installed near the area where the former vent line approached the building, which is where the highest levels of soil contamination were found during closure of USTs #321 and 322. | John Halverson |
| 4/21/1995 | Update or Other Action | Air Force AF memo: 18 April 1995 Underground Storage Tank (UST) Meeting. Elmendorf AFB will accomplish the following actions regarding UST Projects. These actions are based upon conversation between, John Mahaffey, Larry Opperman and yourself. EAFB will make every effort to accomplish a clean closure of a UST removal site if possible. UST removal locations requiring cleanup action will be transferred into the State-Elmendorf Environmental Restoration Agreement (SERA). A list of sites requiring cleanup will be coordinated with your office. The presumptive remedy for contaminated UST sites in the outwash plain only will be bioventing technology. Contaminated soils exceeding cleanup levels may be placed back into the excavation only if the site assessment (SA) indicates a need for further cleanup action. Contaminated UST sites not in the outwash plain will require further investigation to determine appropriate cleanup options. We will make every attempt possible to assure new USTs or new aboveground tanks are not installed in any way that would hamper future access for cleanup. The project will first accomplish removal of all of the USTs. SA information will be used to prioritize sites for cleanup using existing project funds. Additional funding will be requested to complete cleanup if available. Sites not addressed for cleanup due to exhausted funding will be placed into SERA Phase IV. John Halverson signed on April 21, 1995. Memo was signed by Douglas G. Tarbett, Maj, USAF, Chief, Environmental Compliance. CC: 3 WG/JA and 3 SPTG/CE. | John Halverson |
| 10/25/1996 | Update or Other Action | Final Results of SERA Phase III Investigation Results of Follow-On Investigation at ST77-Source Area ST77 is located south of the East-West flight line, northwest of taxiway 14, near Building 32-127. Figure 1 shows the location of the site on Elmendorf AFB and Figure 3 shows the site layout. The soil consists of fine sands and gravel with groundwater about 13 feet bgs. Figure 3 also shows the locations where soil samples were taken during this bioventing study, and the location of a new groundwater monitoring well. Table 3 gives the results of the analytical testing of the soil borings and soil samples taken while installing the well. The results of the analytical testing of groundwater from well 77-WL-01 are given in Table 2. Recommendation for future actions at ST77-ST77 was scored level B under the ADEC Cleanup Matrix in the UST Site Assessment Report (USAF 1994, b). The groundwater in well 77-WL-01 has not been impacted by petroleum. None of the results of the analytical testing on the soil borings at ST77 are above level B in the ACM. It is recommended that the site assessment for ST77 be revised to indicate that the applicable soil cleanup levels in 18 AAC 78.315 are not exceeded, and that this site be permanently closed. | Louis Howard |
| 1/21/1997 | Document, Report, or Work plan Review - other | ADEC letter to Air Force (C. Mayer) re: Final Results SERA Phase III Investigation, Technical Memorandum dated October 25, 1996. The cover letter submitted with it requested ADEC concurrence on the memo and stated that the Air Force would like to have it serve as the SERA Phase III corrective action plan. The memo provides a good summary of the investigation. However, it needs to contain additional information including the copies of the laboratory results, a better description of the soil sample collection depths and supporting information on the project QA/QC. Please submit a complete assessment report with this information included. With regard to using the memo as a corrective action plan, I recommend that each site be considered individually and that a decision document be prepared and signed for each. Comments on the individual areas are provided below. ST77: Following submittal of the complete assessment report and assuming no QA/QC problems exist, please prepare a no further action decision document for ST77. | Louis Howard |
| 2/11/1997 | Leaking Underground Storage Tank Release Confirmed - Petroleum | LUST Site created in CSP for source area ID 76220 ADD; Site added by Shannon & Wilson, Inc. Air Force Relative Risk Evaluation Worksheet dated 8/18/95 does not indicate leaking UST or evidence of contamination. Should this be on database?? | Former Staff |
| 2/11/1997 | Update or Other Action | RI; RI action added by Shannon & Wilson, Inc. on 02/11/1997. Air Force Relative Risk Evaluation Worksheet dated 8/18/95 indicated RI is the current phase. | Former Staff |

| 5/20/1997 | Site Closure Approved | TECHNICAL DOCUMENT TO SUPPORT NO FURTHER ACTION DECLARATION SITE NAME AND LOCATION-Installation Restoration Program Site Site ST77, Underground Storage Tanks (USTs) at Building 32-127 Elmendorf Air Force Base, Alaska Statement of Basis-This decision is based on the following attached references: a. Phase III Site Assessment Work Plan, Final, April 95 b. Final Results SERA Phase III Investigation, Technical Memorandum dated 25 Oct 96 c. Alaska Department of Environmental Conservation's (ADEC) letter dated 21 Jan 97, commenting on reference b. above Description of The Selected Remedy: Based on the current conditions at Installation Restoration Program (IRP) Site ST77, no further action (NFA) at this site is required under the IRP. Declaration: The extent of the soil petroleum hydrocarbon contamination is confined to the soils in the area immediately around the UST locations. The groundwater in well 77-WL-01 has not been impacted by petroleum. None of the results of the analytical testing on the soil borings at ST77 are above level B in the ADEC Cleanup Matrix. POL contamination is below ADEC maximum contaminant levels (MCLs). It has been determined that the selected remedy of no further action under the IRP is protective of human health and the environment because the applicable soil cleanup levels in 18 AAC 78.315 are not exceeded. | Former Staff |
