Chapter 4
• Dissimilar refuse materials are continually generated. These include: (1) coarse refuse in solid form, (2) fine refuse in slurry or dewatered sludge form, and (3) for some sites, combined coarse and fine refuse. The characteristics and quantities of coal refuse may change over time due to changes in geology, production, mining
