The full-scale disposal by landfilling of FGD sludge which has been fixed according to the system developed by Conversion Systems, Inc. (CSI (formerly IU Conversion Systems, Inc.)) has been monitored over a period of roughly four years beginning in early 1979. The investigations have been conducted at the Conesville Power Station of Columbus and Southern Ohio Electric Company where the system was first applied on a full-scale basis starting January, 1977. Principal project objectives (Research Project 1406-2) were to evaluate if full-scale application of the CSI Poz-O-Tec System (1) reflects laboratory and pilot scale projections, (2) causes operating problems, and (3) provides an environmentally acceptable disposal alternative. This report is the final summary document (four total) prepared by Michael Baker, Jr., Inc., for this project. It contains specific data and observations for the last year's (Phase II, Third Interim) activities, summarizes all past water quality and sludge physical testing data, and presents an evaluation of the success of the system with respect to projected results and general environmental acceptability. The subject system for sludge management has generally been determined to be environmentally and operationally sound. Although the fixed sludge permeabilities are slightly higher than desirable, leachate as a result of landfill permeation, if any, has not been detected. The system provides sufficient additional measures other than reduction of sludge permeability to prevent the formation of leachate by permeation. Shear strength of the fixed FGD sludge is significantly improved as compared to that of unfixed sludge. As a result, the landfill area has many potential uses after closure.
