30 CFR § 870.5 - Definitions.
As used in this Part -
Calendar quarter means a 3-month period within a calendar year. The first calendar quarter begins on January 1 of the calendar year and ends on the last day of March. The second calendar quarter begins on the first day of April and ends on the last day of June. The third calendar quarter begins on the first day of July and ends on the last day of September. The fourth calendar quarter begins on the first day of October and ends on the last day of December.
Excess moisture means the difference between total moisture and inherent moisture, calculated according to § 870.19 for high-rank coals or the difference between total moisture and inherent moisture calculated according to § 870.20 for low-rank coals.
Expended means that moneys have been obligated, encumbered, or committed for reclamation by contract by the OSM, State, or Tribe for work to be accomplished or services to be rendered.
In situ coal mining means activities conducted on the surface or underground in connection with in-place distillation, retorting, leaching or other chemical or physical processing of coal. The term includes, but is not limited to, in situ gasification, in situ leaching, slurry mining, solution mining, bore hole mining, and fluid recovery mining. At this time, part 870 considers only in situ gasification.
Inherent moisture means moisture that exists as an integral part of the coal seam in its natural state, including water in pores, but excluding that present in macroscopically visible fractures, as determined according to § 870.19(a) or § 870.20(a).
Lignite coal means consolidated lignite coal having less than 8,300 British thermal units per pound, moist and mineral-matter-free. Moist, mineral-matter free British thermal units per pound are determined by Parr's formula, equation 3, on page 222 of “Standard Specification for Classification of Coals by Rank,” in American Society for Testing and Materials ASTM D 388-77 (Philadelphia, 1977). Parr's formula follows:
Mineral owner means any person or entity owning 10 percent or more of the mineral estate for a permit. If no single mineral owner meets the 10 percent rule, then the largest single mineral owner shall be considered to be the mineral owner. If there are several persons who have successively transferred the mineral rights, information shall be provided on the last owner(s) in the chain prior to the permittee, i.e. the person or persons who have granted the permittee the right to extract the coal.
Reclaimed coal means coal recovered from a deposit that is not in its original geological location, such as refuse piles or culm banks or retaining dams and ponds that are or have been used during the mining or preparation process, and stream coal deposits. Reclaimed coal operations are considered to be surface coal mining operations for fee liability and calculation purposes.
Surface coal mining means the extraction of coal from the earth by removing the materals over the coal seam before recovering the coal and includes auger coal mining. For purposes of subchapter R, reclaiming coal operations are considered surface coal mining.
Ton means 2,000 pounds avoirdupois (0.90718 metric ton).
Total moisture means the measure of weight loss in an air atmosphere under rigidly controlled conditions of temperature, time and air flow, as determined according to either § 870.19(a) or § 870.20(a).
Underground coal mining means the extraction of coal from the earth by developing entries from the surface to the coal seam before recovering the coal by underground extraction methods, and includes in situ mining.
