Problems/Comments

The Motor Pool Buildings 3492/3494/3496 are equipment shops and maintenance facilities at Fort Wainwright. Investigations have been conducted at the Motor Pool parking lot adjacent to Buildings 3492, 3494, and 3496 starting in 2007 with a geotechnical investigation and field screening in 2009, with multiple areas of high PID readings observed. Minor debris was encountered in the parking lot during some of these excavations, including empty crushed drums, cables, piping, and other miscellaneous debris. The results of the 2009 FTW334 Organizational Vehicle Parking sites report suggest multiple releases occurred throughout the Motor Pool area from various historical sources. In 2015, an RI/RA was conducted and based on these results, the site was recommended for NFA. However, in 2019 contaminated soil was discovered underneath Buildings 3492 and 3494 while cutting through the concrete floor to install rebar cages for the foundations of crane equipment, and in 2020 two POL spills were reported along the east fenceline, attributed to minor leaks from vehicles parked in the lot over the winter. In 2023, an electrical conduit trench was excavated and detected Pentachlorophenol (PCP) above DEC MTG CULs in sidewalls. The source of the PCP is currently unknown. There are three known source areas associated with this site: Fenceline Spill site, Crane Sites, and Fenceline PCP sites. This site includes multiple spills: Spill no. 09309915202; spill date = 6/1/09; PERP file no. = 108.02.017; substance = gasoline and diesel; quantity = unknown. Spill no. 09309918801; spill date = 7/7/09; substance = gasoline; quantity = unknown. Spill no. 20309912104; spill date = 4/30/2020; substance = petroleum; quantity = unknown; description: historical petroleum contamination found near the east fence line at Bldg 3496. Spill no. 20309917501; spill date = 6/23/2020; substance = petroleum; quantity = unknown; description: historical petroleum contamination encountered. Spill no. 20309917602; spill date = 6/24/2020; substance = petroleum; quantity = unknown; description: historical petroleum contamination encountered.

11/15/2011 Document, Report, or Work plan Review - other Final Miscellaneous Stockpile Characterization After-Action Report, November 2011Buildings 3492, 3494, and 3496; Stockpile #3 Between 9 and 10 July 2010, Stockpile #3 was field screened and sampled. A total of 100 samples for field screening were collected from Stockpile #3 with results rangin g from 0.3 ppm to 129 ppm. A total of 20 analytical samples were collected from the areas with the highest field screen readings and analyzed for GRO, DRO, RRO, VOCs, SVOCs, PCBs, R CRA metals, and pesticides. Con centrations of DRO and RRO exceeded ADEC cleanup criteria throughout the stockpile with maximum results of 3,660 mg/kg and 20,900 mg/kg, respectively. One sample (10FWA-MSP-SO-W38) had an exceedance of tetrachloroethene (PCE) with a concentration of 0.047 mg/kg. All other samples were nondetect for PCE, indicating this was an anomaly and not indicative of the soil in the stockpile. All other analytes were below ADEC cle anup criteria and RCRA action levels.

10/27/2016 Update or Other Action 2009 Removal Action Report for Bldg 3485 Underground Vault was reviewed. An 8x8 ft wooden vault was removed, and approximately 120 cy of petroleum-contaminated soil was excavated and thermally treated. The vault was located approximately 125 ft east of the former UST fuel tanks referred to in previous database entries. Post-excavation confirmation soil samples indicated contamination remaining on the north and east walls of the excavation, with diesel range organics (DRO) concentrations ranging from 723 to 2,400 mg/kg. Further delineation of the site was recommended by the report. Current records do not indicate that characterization or additional remediation has yet been conducted. Joy Whitsel
11/23/2016 Meeting or Teleconference Held The site was discussed during a teleconference call on November 23, 2016. Building 3485 remedial investigation was completed under the March Creek work plan during July and August of 2016. The Restoration Project Managers are recommending the site continue to a proposed plan and ROD. Dennis Shepard
12/13/2016 Meeting or Teleconference Held A two day Federal Facilities Agreement (FFA) and Stakeholders meeting was held on December 13 & 14, 2016. The main focus of the meeting was to develop a site discovery and site intake process that would satisfy requirements of the Fort Wainwright FFA, RCRA Permit, and two party agreements. The Army, EPA and DEC committed to a flowchart of the preliminary source evaluation process. Timelines were established for scoping a land use control implementation plan (LUCIP) and developing a contracting schedule for Fort Wainwright contaminated site investigations and remedial actions. Seven sites were proposed for inclusion into the FFA (three party agreement) by the Army and the RPMs documented the assignment of the regulatory path for these sites using a newly developed and agreed to signature form. Dennis Shepard
12/15/2016 Update or Other Action The building 3485 "Potential new source" signature form was signed by restoration project managers (RPMs). The RPMs agreed with the Army recommendation to investigate the site under the 3 party agreement. Dennis Shepard
