National Dam Inspection Program. Refuse Settling Basin (NDI Number PA 00908, PennDER Number 63-78), Ohio River Basin, Sawmill Creek, Washington County, Pennsylvania. Phase I Inspection Report.

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 and/or maintenance efforts.
