Problems/Comments

On July 10, 2010 an employee turned on a fuel pump to transfer #1 diesel fuel to a 500-gallon aboveground heating oil tank. The fuel transfer was left unattended and ~2342 gallons were released to the ground surface. During initial cleanup activities evidence was noted of contamination that may have been from an additional source. This facility is at the same location as the former federal facility Nike Site JIG; Hazard ID 3248. Interim removal actions consisting of excavation of the spill were immediately executed by the responsible party. Upon recognition of possible evidence of historical contamination, DEC required submission of a work plan before continuing with removal activities. This work plan agreed to test the possible area of historic contamination with a full suite analysis, as well as to perform forensic testing to separate the recent release from weathered diesel fuel. It was originally thought that excavation would be able to reach the extent of the contamination. However, the excavation was limited by the building foundation and boiler conex on the north side of the spill, and by depth on the southern end of the spill. In order to restore safe operations at the Alaska Pacific Powder Company Plant, an addendum to the work plan was submitted and approved by DEC. This work plan allowed the excavation to be backfilled, with bioventing pipes installed at the southern end of the spill. An additional work plan for further site characterization will be submitted in the spring of 2011. Contaminants of concern from lab results include DRO, Arsenic, Chromium, 1,2,4 Trimethylbenzene, 2 Methyl Napthalene, and Benzene. At this time, the contamination found at this site appears to be petroleum related. A discussion of the results for arsenic and chromium will be included in a future conceptual site model. --Updated 2011--- The Phase I Site Characterization Work Plan was approved on July 26, 2011. A work plan for a second effort to deal with the potential groundwater and vapor intrusion issue at the site is expected to be submitted for review in Sept. 2011.
