Problems/Comments
In 2008, during the excavation of a PERP-managed 2007 20-gallon diesel spill at the Crowley Marine Bulk Storage Facility, a lens of discolored fill material was noted between 2 and 5 inches below ground surface in the west half of the excavation. The lens contained a hydrocarbon odor and an elevated PID screening level of 268 ppm. This soil was not over-excavated or further delineated during the 2008 effort.

| 10/6/2010 | Document, Report, or Work plan Review - other | According to the Soil Removal Action Crowley Fuel Station, Mcgrath, Alaska prepared by Shannon & Wilson, dated October 17, 2008, a separate, area of petroleum impacted soil from an unknown source was encountered. The new site was discovered during the ADEC Prevention and Emergency Response Program’s (PERP) managed excavation of a May 2007 20-gallon diesel spill at the Crowley Marine Bulk Storage Facility. During this cleanup effort, a lens of discolored fill material was noted between 2 and 5 inches below ground surface (bgs) in the west half of the excavation. The lens contained a hydrocarbon odor and an elevated photo ionization detector (PID) reading of 268 parts per million by volume (ppmv). This soil was not over-excavated or further delineated during the 2008 effort, because it was determined that it was not associated with the May 2007 release. Therefore, further evaluation of the potentially impacted soil is warranted. | Grant Lidren |

Eleven soil borings were advanced to a depth of 0.5 to 2 feet bgs. A discolored soil lens was encountered in eight borings: B1, B2, B4, B5, B7, B8, B9, and B10. Seven soil samples collected from B1, B3, B5, B6, and B10 did not contain petroleum constituents above ADEC cleanup levels. | Grant Lidren |
