| 2/9/2007 | Update or Other Action | (Tamar Stephens comment copied from Old Waste Disposal Area Site) Contaminated sites program staff Tamar Stephens reviewed and approved final Sampling Report for sampling conducted during summer 2006. Investigation of Middle Salt Lagoon sampled showed petroleum contamination very low or non-detect; no halogens detected. Investigation of eight debris concentration areas detected occasional minor petroleum contamination below cleanup levels. Magnetic locator did not find any buried metal under Quonset hut, and soil samples did not detect PCBs. Additional investigation of former Communications Area above-ground storage tank location found that petroleum contamination is limited and does not require cleanup. The report also provides a detailed mapping and photographic log of exposed debris. Debris is present throughout the Old Waste Disposal Area, partially or completely imbedded in permafrost. Stephens noted that although the contaminated sites program does not regulate the debris, the Navy should be aware that a few items of metal debris protruded greater than 2 feet from the ground surface, and pose a safety hazard, particularly to snow machine travel in the winter | John Carnahan |

| 1/25/2013 | Exposure Tracking Model Ranking | Initial ranking with ETM completed for source area id: 71538 name: NARL - Middle Salt Lagoon. This is an auto action that was triggered by an administrative fix to correct reporting problems in the Unranked Sites Report. This is not an actual ETM ranking and no answers were altered within the ETM. The only part of the record affected by this fix may be the ranking dates. (Reese) | Kristin Thompson |
