At <br /> <br />the present time there is no commercial <br /> <br />market for fly or bottom ash in this <br /> <br />area; nonetheless, the participants will <br /> <br />attempt to market these products should <br /> <br />a market develop. Surplus fly and bottom <br /> <br />ash will be disposed of at the mine or a <br /> <br />state or locally-approved land-fill area. <br /> <br />According to the September 1973 issue of <br /> <br />"Power Engineering," a development project <br /> <br />is underway to investigate the utilization <br /> <br />and disposal of stack cleaning waste by- <br /> <br />prdduct material.
