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.

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. |

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. |

DEC approved the Final Sampling and Analysis Plan for FTW406 BDG 3485 Parking Lot. Construction activities associated with this SAP include removing existing asphalt, excavation and grading of soil, installing electric power poles, laying underground cable, landscaping, and fencing. The disturbance of soil at the site may result in discovery of contaminated soil, and the contaminants of potential concern at the existing “Motor Pool Parking Lots Bldgs 3485/3492/3494/3496” contaminated site are diesel range organics (DRO), gasoline range organics (GRO), benzene, toluene, ethylbenzene, xylene, Resource Conservation Recovery Act metals, nickel, and vanadium. |

DEC approved Amendment 1: August 12 2019, Sampling and Analysis Plan (SAP) for FTW406 BLDG 3485 Parking Lot, U.S. Army Garrison Alaska. The addendum includes the FTW406 Luzon Road Widening and Drainage project under the SAP approved by DEC on August 7, 2019. Photoionization detector (PID) readings showed that potentially contaminated soil may be present in the area of the Luzon Road construction project. New activities added to the previously approved SAP include excavation of 9,610 cubic yards of soil at Luzon Road and 45 cubic yards at associated culvert inlets. |

CERCLA Proposed Plan |
DEC has reviewed and submitted comments on the Proposed Plan (PP)for the Spill Area South of Building 3485, Motor Pool Buildings 3492, 3494, 3496, and Northern Lights Housing Area Sites, which details the site histories, investigation results, and path forward to address remaining contamination present at these sites on Fort Wainwright. Management of each of the three sites are recommended by the PP to be transferred to the State of Alaska under the Two-Party Agreement, as the Environmental Protection Agency (EPA) does not have authority for further investigation or remediation under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Section 101. |
