Enviorment/Energy: shallow, highly aggitated marine water/ high energy. Bituminous coal is so-called because it contains a tar-like substance called bitumen. In the U.S., bituminous coal can be found in Illinois, Kentucky, West Virginia, Arkansas (Johnson, Sebastian, Logan, Franklin, Pope, and Scott counties), and locations east of the Mississippi River. Burning the coal releases trace mineral impurities into the air as pollution. It has a carbon content of between 77 and 87% on a dry ash-free basis and a heating value that is much higher than lignite or sub bituminous coal. Bituminous coal contains moisture of up to approximately 17%. Coal is a biochemical rock formed by the accumulation of plant material that is later buried and partially altered to a carbon-rich rock. Therefore, large combustion units and well-maintained ones generally have lower pollution output.
