摘要

CHA was contracted by Lockheed Martin (a contractor to the United States Environmental Protection Agency) to perform site assessments of selected coal combustion surface impoundments (Project 0-381 Coal Combustion Surface Impoundments/Dam Safety Inspections). As part of this contract, CHA was assigned to perform a site assessment of Allegheny Energys Ash Pond 3 and Ash Pond 4 at the R. Paul Smith Power Station. The Power Station is located in Williamsport, Maryland, and the ash lagoons are in Falling Waters, West Virginia as shown on Figure 1 Project Location Map. CHA made a site visit on October 20, 2009 to inventory coal combustion surface impoundments at the facility, perform visual observations of the containment dikes, and collect relevant information regarding the site assessment.
