Update or Other Action |
We are creating new parking areas with HBO's for Bldgs 3014 and 3015 as shown on the attached drawings. Both areas are close to the former Bldg 3015 drum storage area, but we do not anticipate they will encounter anything onerous, however, there is a potential for them to encounter some small areas of petroleum. Major contamination found will be stockpiled, sampled, and disposed of IAW State and Federal laws and regs. Contractor will be trenching up to 24 inches for electric conduit and boring up to 36 inches to install the HBO Posts.
All areas will be covered with asphalt.Bldg 3014 parking area is north of current area under investigation. So far, only petroleum products have been found. We are still waiting for the rest of the analyticals before completing the new utility installation in that area.
Contractor will have Travis-Peterson performing environmental survey tasks during all excavation activities.
DEC has no objection to the shallow excavations
If contamination is encountered, contractor will stop work and notify the Environmental Office and wait for further instructions.

Update or Other Action |
Staff recieved a draft work plan for additional excavation at the site. A response was sent as follows: I have the final 2010 report for the work Jacobs did at this site but I do not even have a draft of the work Doyon/TPECI did at the site. My approval letter for the Jacobs report asked for a plan to completely characterize the site. This work plan seems to only address additional contamination found by some construction contractor. I will not approve the implementation of this plan until I have the Doyon report and a schedule for completing the characterization of the site by an environmental firm, not a construction contractor. |

Draft Work Plan Environmental Investigations various Sites, Fort Wainwright Alaska January 2015 was reviewed. This this work plan addresses 17 sites at Fort Wainwright. The plan was written in UFP-QAPP but has major deficiencies requiring a complete rewrite of the document. Detailed comment was sent to the Army. |

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. |

CERCLA RI Plan Approved |
DEC completed a backcheck and partial approval of the Final Supplemental Remedial Investigation (SRI) Work Plan for 33B Barracks, Building 1054, Building 3014, and the Montgomery Road Extension. The objective of each SRI is to characterize the nature and extent of contamination and evaluate the human health and ecological risk. The SRI results will be used to develop preliminary remediation goals and identify remedial alternatives that will be further evaluated in a feasibility study (FS). The work plan is intended for use in conjunction with the Risk Assessment Work Plan, which is currently under regulatory review.
Several comments on the draft work plan requested contamination in soil to be delineated to at least the most stringent of DEC’s promulgated cleanup levels, typically the migration to groundwater cleanup levels. DEC recognizes the importance of the intended field sampling, and the Army’s commitment to ensureanalytical methods have limits of detection that are able to achieve the DEC migration to groundwater cleanup levels. As the Army did not identify the fate and transport model that will be used to evaluate the migration to groundwater pathway, DEC will evaluate the results of this field effort as presented in the draft report to evaluate whether the nature and extent of the contamination has been delineated. DEC will identify at that point if sufficient information has been gathered to determine the fate and transport of contamination over time. Data gaps may persist after the SRI effort due to this oversight.
Additionally, due to the recent DEC Bulk Petroleum Hydrocarbon Noncancer Toxicity for Human Health Risk Assessments Technical Memorandum (DEC, May 2023), DEC does not find the language in Section 1.3 regarding bulk petroleum risk to be in accordance with guidance, and the Army must address this issue further during comment resolution of the Risk Assessment Work Plan. All other responses to comments have been incorporated into the final document and are accepted.
Lastly, on May 24, 2023, DEC was informed that the US Army Corps of Engineers (USACE) had begun conducting sampling without DEC approval of the SRI work plan. In accordance with 18 AAC 75.335(b) and 18 AAC 75.360(2), work may not begin at a site until the work plan has been approved. This formally documents the Army’s non-compliance with the above-referenced regulations and provides notice that future non-compliance with state regulations may result in a Compliance Advisory Letter or formal enforcement actions, as appropriate. |
