Action Information
Action Date | Action | Description | DEC Staff |
---|---|---|---|
8/31/1983 | Update or Other Action | Engineering-Science (1983) reviewed records on file at the Bioenvironmental Engineering Office and interviewed shop personnel to determine the types of hazardous materials, waste quantities, and disposal methods. Following these interviews, drain outfalls were identified as potential sources of environmental contamination because of the nature of compounds thought to have been discharged down floor drains in the building. The vehicle maintenance shop generates 4500 gallons per year of used hydraulic fluid and engine oil, and 1200 gallons of used PD680. From mid-1940 until 1979, waste material was discharged to storm drains that led to a leach field, was removed by a contractor, or was used to control dust on base roads. Since 1979, disposal has been through OPDO (now DRMO). | Louis Howard |
9/2/1988 | Update or Other Action | Engineering-Science (1983), in the IRP Phase I, Records Search, indicated Building 21-900 is an automotive maintenance facility which is used to maintain most vehicles on base. A series of floor drains is connected to 2 sumps that used to drain into a seepage pit north of the building. Spilled petroleum products and PD-680 used in vehicle cleaning operations have been washed into the drains. Currently, the sumps discharge to a storm drain. The floor drains from the mechanical room still still discharge to the seepage pit. A catch basin on the south side of the building also runs to the seepage pit (Ritz, USAF, personal communication, 08 March 1989). In 1988, Black & Veatch (1990) placed a soil boring, collected soil samples at 15 feet and 20 feet below ground surface, and finished the boring as a monitoring well (IS7-01) for site IS-7 Floor Drain at Building 21-900. After these activities, a water sample was collected from the monitoring well. The groundwater sample was contaminated with chloroform at 0.32 ug/L and trichloroethene at 76 ug/L. These levels are above the drinking water MCLs. TPH level was 2,000 ug/L. Because of the position of the monitoring well relative to the dry well, sumps, and other potential sources, the contamination detected in the groundwater may not be representative of potential contamination from the source. Black & Veatch (1990) estimated that the direction of groundwater flow was from the north to the south. If that is accurate, the well may be located upgradient of SD30 sources. | Louis Howard |
4/1/1993 | Update or Other Action | DETERMINATION OF NO FURTHER ACTION SOURCE SD30, BLDG 21-900 APRIL 1993 received. Source SD30 (Building 21-900) is included in Operable Unit (OU) 4 for purposes of remedial investigation at Elmendorf AFB under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Ten maintenance facilities were grouped together in OU4 for a Limited Field Investigation (LFI) during 1992. These maintenance facilities were suspected of having floor drains that emptied into dry wells, leach fields, or storm drains. Past practices at these buildings may have released hazardous substances to the environment through the floor drains and outfall structures. Source SD30 was originally identified as a potential source of contamination in the 1983 Phase 1 record search. It is located on the northeast corner of the intersection between Second Street and Plum Avenue. It is approximately 3,500 feet south of the west end of the east/west runway. Building 21-900 is an automotive maintenance facility that services most U.S. Air Force (USAF) vehicles on the base. The vehicle maintenance shop generates 4,500 gallons per year of used hydraulic fluid and engine oil, and 1,200 gallons of used PD680. As-built drawings indicate that the building's floor drains led to sumps and discharged somewhere north of the building and to a dry well south of the building. The drains now discharge to the storm sewer; latrines are connected to the sanitary sewer. As a result of the geophysical survey and soil sampling conducted at SD30, the recommended action for the outfall structure source areas investigated at SD30 is No Further Action (NFA). The primary criterion used to place sources into the NFA category as a result of the LFI at SD30 was whether the concentration of contaminants in any sample obtained during the LFI exceeded the risk-based criteria specified by the regulatory agencies. None of the soil samples collected during the LFI at SD30 contained analytes in excess of risk-based criteria. The criteria for NFA were met at each of the source sampling locations; therefore, NFA is justified for these locations. Groundwater contamination has been identified upgradient* of SD30. This upgradient contamination near Source SD30 will be investigated during the OU 3 remedial investigations. The United States Air Force (Elmendorf Air Force Base), U.S. Environmental Protection Agency Region 10, and the Alaska Department of Environmental Conservation have completed a review of the information provided in the Final OU4 Limited Field Investigation Report for the source area located at Source SD30, Building 21-900, on Elmendorf Air Force Base. Based on this review, the above agencies have determined that No Further Action for purposes of investigation or study is justified for SD30. NOTE TO FILE: This upgradient source has been identified as the Fairchild Avenue Plume. The Fairchild Avenue TCE plume is one of the Site ST37 chlorinated solvent plumes. The Fairchild Avenue plume is located in the western portion of the OU 5 program area and south of 23rd Street. The plume is approximately 5,000 feet long and covers approximately 70 acres. It is currently defined by the following groundwater wells: 49WL-01, OU3MW-05, OU3MW-11, OU3MW-13, OU5MW-34, OU5MW-37, OU5MW-38, OU5MW-39, OU5MW-40, and OU5MW-43 (Figures 1.1 and 3.1). Trenches used for waste disposal are suspected to be the unconfirmed source of the TCE contamination. | Louis Howard |
4/21/1995 | Update or Other Action | AF memo: 18 April 1995 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 |

10/27/1996 | Site Closure Approved | Site is being addressed under CERCLA OU4 Source Area SD30. None of the soil samples collected during the limited field investigaiton (LFI) at SD30 contained analytes in excess of risk based criteria. The criteria for No further action decision (NFA) were met at each of the source sampling locations. Source of the groundwater contamination has been identified upgradient of SD30. This upgradient contamination near Source SD30 will be investigated during the OU3 remedial investigation. No Further Action for the purposes of investigation or study is justified for SD30. The decision document was signed in May 7,1993 for SD30 by USAF Oscar V. Bryan Colonel Base Civil Engineer April 27, 1993 and EPA Marcia Combes and ADEC Jennifer Roberts on May 7, 1993. However, groundwater is still contaminated and will be monitored while undergoing natural attenuation. | Former Staff |
