Abstract
The purpose of the investigation is to make a determination on whether or not the dam constitutes a hazard to human life or property. The Mine No. 60-Pond 6 is classified as a 'high' hazard dam. In the event of a dam failure, at least 5 inhabited dwellings, several roads, a railyard and a reservoir could be subjected to damage, and the loss of more than a few lives could result. The Mine No. 60-Pond 6 is owned by the Bethlehem Mines Corporation, Eighty-Four, Pennsylvania 15330. The field inspection of Mine No. 60-Pond 6 was performed on 18 March 1981 and 26 March 1981 and consisted of: Visual observations of the embankment crest and slopes, groins and abutments; Visual observations of the principal (and emergency) spillway including approach channel, overflow section, and discharge channel; Visual observations of the embankment's downstream toe area including drainage channels and surficial conditions; Visual observations of downstream conditions and evaluation of the downstream hazard potential; Visual observations of the reservoir shoreline and watershed; Transit stadia surveys of relative elevations along the embankment crest centerline, spillway, a normal operating level during inspection.
