Background Information For Standards Of Performance: Coal Preparation Plants Volume

Coal preparation plants prepare various types of coal in response to market demand. Three types of preparation plants are common: (1) "complete preparation," those that clean both coarse and fine coal; (2) "partial preparation," those that clean only coarse coal; and (3) "coal crushing," where the coal is merely crushed to a specified maximum size.
