Abstract:

The general condition of the Refuse Settling Basin is considered to be fair. This assessment is based on visual observations that indicate a possible inadequate margin of safety against slope failure of a high ground water level exists in Embankment A. The condition is not considered to represent an immediate threat to the structure because of the relatively low impoundment pool elevation. It should, however, be evaluated. If a high ground water does not exist in Embankment A, the facility can be considered to be in good condition. The structure is classified as an intermediate size, high hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood PMF as the Spillway Design Flood for an intermediate size, high hazard dam. The visual inspection indicated several minor deficiencies in addition to the possible high ground water condition. The deficiencies can be corrected or improved through implementation of the following recommended evaluation, remedial, monitoring andor maintenance efforts.
