Abstract
Koppers Petrolia Plant - No. 3 Reservoir Dam is a zoned, earthfill dam owned and operated by the Koppers Company, Inc. The dam has a crest length of 710 feet, a maximum height of 59 feet, and a maximum storage capacity of 278 acre-feet. The dam is classified as a 'High' hazard - 'Intermediate' size dam. Hydraulic/Hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillways will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillway is therefore considered 'adequate'. The dam was found to be in fair overall condition at the time of inspection. Several items of remedial work should be performed by the owner without delay.
