Acid-forming materials-Earth materials that contain sulfide minerals or other materials which, if exposed to air, water or weathering processes, form acids that may create acid drainage.
Adjacent area-Land located outside the permit area, where air, surface or groundwater, fish, wildlife, vegetation or other resources protected by this chapter may be adversely affected by surface mining activities.
Affected area-Land or water upon or in which surface mining activities are conducted or located. The term includes land in which the natural land surface has been disturbed as a result of or incidental to the surface activities of the operator, including, but not limited to, private ways and roads appurtenant to the area, land excavations, workings, refuse banks, spoil banks, culm banks, tailings, repair areas, storage areas, processing areas, shipping areas and areas in which structures, facilities, equipment, machines, tools or other materials or property which result from or are used in, surface mining operations are situated. The term includes the land affected by the construction of new roads or the improvement or substantial use of an existing road to gain access to the site or for hauling from the site.
Aquifer-A zone, stratum or group of strata that can store and transmit water in sufficient quantities for a specific use.
Auger mining-A method of mining coal at a cliff or highwall by drilling holes into an exposed coal seam from the highwall and transporting the coal along an auger bit to the surface.

Blast-A detonation of explosives.
Blasting-The detonation of explosives
Coal processing waste-Earth materials which are separated and wasted from the product coal during cleaning, concentrating or other processing or preparation of coal.
Coal refuse-Any waste coal, rock, shale, slurry, culm, gob, boney, slate, clay and related materials, associated with or near a coal seam, which are either brought aboveground or otherwise removed from a coal mine in the process of mining coal or which are separated from coal during the cleaning or preparation operations. Coal refuse shall include underground development wastes, and coal processing wastes, excess spoil, but does not mean overburden from surface mining.
Combustible material-aterial that is capable of burning, either by fire or through oxidation, accompanied by the evolution of heat and a significant temperature rise.
Compaction-Increasing the density of a material by reducing the voids between the particles and is generally accomplished by controlled placement and mechanical effort such as from repeated application of wheel, track or roller loads from heavy equipment.
Contouring-Reclamation of the land affected to approximate original contour so that it closely resembles the general surface configuration of the land prior to mining and blends into and complements the drainage pattern of the surrounding terrain with no highwall, spoil piles or depressions to accumulate water and with adequate provision for drainage.
Cropland-Land used for the production of adapted crops for harvest, alone or in a rotation with grasses and legumes, and includes row crops, small grain crops, hay crops, nursery crops, orchard crops and other similar agronomic and horticultural crops.
Degree-The inclination from the horizontal.
Disturbed area-An area where vegetation, topsoil or overburden is removed or upon which topsoil, spoil, coal processing waste or noncoal waste is placed by surface coal mining activities. Those areas are classified as disturbed until reclamation is complete, and the performance bond or other assurance of performance required by Chapter 86 Subchapter F (relating to bonding and insurance requirements) is released.

Hydrologic balance-The relationship between the quality and quantity of water inflow to, water outflow from and water storage in a hydrologic unit such as a drainage basin, aquifer, soil zone, lake or reservoir. It encompasses the dynamic relationships among precipitation, runoff, evaporation and changes in groundwater and surface water storage.
Hydrologic regime-The entire state of water movement in a given area. It is a function of the climate and includes the phenomena by which water first occurs as atmospheric water vapor, passes into a liquid or solid form, falls as precipitation, moves along or into the ground surface, and returns to the atmosphere as vapor by means of evaporation and transpiration.

Include-Including but not limited to.
Intermittent stream-A body of water flowing in a channel or bed composed primarily of substrates associated with flowing water, which, during periods of the year, is below the local water table and obtains its flow from both surface runoff and groundwater discharges.
Land use-Specific uses or management-related activities, rather than the vegetation or cover of the land. Land uses may be identified in combination when joint or seasonal uses occur. Changes of land use from one of the following categories to another shall be considered as a change to an alternative land use which is subject to approval by the Department. Land use may be defined as:
