In February of 1988, EPA submitted a report to Congress on wastes from the combustion of coal by electric utility power plants. This report addressed wastes generated from combustion of coal by electric utility power plants and not co-managed utility coal combustion wastes, other fossil fuel combustion wastes, and wastes from non-utility boilers. 

In March of 1999, EPA submitted a report to Congress addressing the remaining wastes not addressed in the 1988 report.
