National Dam Inspection Program. PA-657 Dam (Acme Dam) (NDI I.D. Number PA-00828, PennDER I.D. Number 65-133), Ohio River Basin, Jacobs Creek, Westmoreland County, Pennsylvania. Phase I Inspection Report
Based on a visual inspection, past performance, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and the hazard classification is considered to be high. The emergency spillway is capable of discharging the peak inflow resulting from a storm of PMF intensity and is, therefore, considered adequate. It is recommended that the owner: (a) Repair the damaged pond drain gate control and replace the missing manhole cover atop the service spillway riser. Consideration should be given to redesigning the gate control mechanism to protect it from future vandalism. (b) Consult with the U.S.D.A., Soil Conservation Service, to assess the erosion on the upstream slope in the area of the service spillway riser and implement any remedial measures deemed necessary. (c) Curtail the unauthorized vehicular travel across the embankment and repair and reseed any damaged (bare) areas. If control of unauthorized travel is not practical, some provision should be made to protect the embankment from rutting and erosion by placing a layer of gravel or stone across the crest. (d) Develop a formal operation and maintenance manual to ensure the continued proper care of the facility. In addition, a formal warning system should be implemented which provides detailed procedures to protect the lives and property of downstream residents. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy percipitation.
