Summary

Description

Observations obtained during the August 6th 7th field surveys are part of the continuing assessment of the fate and effects of spilled Prudhoe crude upon the Atigun Flood Plain system. The continuing field assessments are performed as per the intents of Phase III and IV of the National and Regional Pollution Response Contingency Plans. The June 1920 and 2628, 1979 field assessment survey showed that a large amount of oil had become entrapped within the flood plain sediments and root masses of riparian vegetation. The August field survey was aimed at: 1 determining the extent of the flood plain still affected by stored oil; 2 determining the level of threat the stored oil could still pose or could continue to pose to the habitatfish and wildlife resources of the Atigun Flood Plain; and 3 determining if continuation or modification of spill containments and cleanup activities were still mandated.
