National Dam Inspection Program. Silt Pond B, (NDI Number PA 00824 PENN DER Number 63-77) Ohio River Basin, Pigeon Creek, Washington County, Pennsylvania. United States Steel Corporation, Raw Materials Division. Phase I Inspection Report
Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of Silt Pond B is considered to be good. This assessment is based primarily on visual observations of the embankment and appurtenances and hydrologic/hydraulic analyses of reservoir/spillway capacity. 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. Silt Pond B's Spillway Flood is the Probable Maximum Flood. Spillway capacity is 'adequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be in excess of 100 percent of the PMF. The field inspection indicated several minor deficiencies which can be corrected or improved through implementation of the following recommended evaluation, remedial and/or maintenance efforts.
