The release of over 5 million cubic yards of coal ash from the Tennessee Valley Authority's Kingston, Tennessee, facility in December 2008 serves as an important reminder of the need for our continued diligence on disposal units where coal combustion wastes are managed. The coal ash from the facility flooded more than 300 acres of land, damaging homes and property. It is critical that we all work to the best of our abilities to prevent a similar catastrophic failure and resultant environmental damage. One of the first steps in this effort is to assess the stability of the impoundments and similar units that contain coal combustion residuals and by-products to determine if and where corrective measures may be needed and then to carry out those measures as expeditiously as possible. This report for the Martins Creek facility assesses the stability of two management units. The Martins Creek facility experienced a discharge water system failure in August 2005, causing a significant release of water and fly ash. Water and fly ash spread into surrounding fields and into Oughoughton Creek; fly ash was discharged into the Delaware River as well. This assessment is based on site observations made on Wednesday, September 2, 2009 by Dewberry and Dewberrys review of furnished documentation, much of which is included as Doc. 2 through Doc. 45 in Appendix A. Selected documents are referenced in the text of this report, as appropriate.
