Mar 15, 2019 The coal's sulfur content is generally less than 2 percent by weight. Nitrogen makes up approximately 0.5 to 2 percent of the coal's weight. Sub-bituminous coal typically is found near the surface, which results in lower mining costs, making it a relatively inexpensive coal.

Coal companies have to meet strict mining requirements, reclaiming the land and protecting the environment. Prior to mining, coal companies are required to obtain various permits, including those related to air and water quality. Following surface mining, the land must be returned to original or better conditions suitable for plants and wildlife.
