Site Ranked Using the AHRM |
Site reranked. Williams reports that site is not near school. Site Access Value changed from 3 to 2. Surface water is > 1 mile away, so SW Exposure Index Value changed from 0.4 to 0. Williams questions validity of report with high concentration levels. Basically, the site is a tar pit from the turn of the century. |

Received EPA report on Fort Saint Michael regarding tar pits dated February 2000. In that report samples were taken of the tar pits which resulted in the following: Tar pit 100 yards from shore - DRO 19,000 ppm, RRO 29,000 ppm, Phenanthrene 71,000 ppm. Tar pit near the old airstrip - DRO 27,000 ppm, RRO 38,000 ppm, Phenanthrene 63,000 ppm, Chrysene 34,000 ppm. |

Update or Other Action |
Draft Phase I ESA received. Areas of concern documented included "tar pits" (see Hazard ID 27877) at southern boundary of airstrip and adjacent property, former dump at north end of airstrip, former barrel and battery dumpsite also at the north end, and a former drum disposal area. Site activities in 2006 by NALEMP included removal of empty barrels, but it is unknown whether all batteries and barrels were removed nor what surface or subsurface impacts may remain. The dumpsite has not been characterized, and the contractor provided recommendations for management of the tar stained areas. |

Document, Report, or Work plan Review - other |
ADEC issues comments on the March 2017 Draft Lead-Contaminated Soil Removal Action Report (received by ADEC 3/31/17). The US Shipyard Large Building, US Shipyard Small Building, and small area southwest of the Medium Building appear to be eligible for no further action. The Bakery and US Shipyard Medium Building/Drum Dump area are not eligible for closure at his time because lead does not meet the cleanup level of 400 mg/kg, and there is not a regulatory definition for a “deminimus” amount of lead contamination. A favorable 95% UCL calculation or additional soil removal will be required for site closure at the Bakery and US Shipyard.
