Priority 3 (P3): Land and Waters Problem Types
A ledge that forms a single level operation along which mineral or waste materials are excavated. A solid bench is that portion of a bench formed on solid, unexcavated material. A fill bench is that portion of a bench usually consisting of unconsolidated spoil material extending outward from the solid bench.
An AML area used to dispose of any kind of industrial or residential waste not related to mining or processing.
Any equipment or buildings used to mine, process, or transport coal or mineral ores.
The refuse or waste removed from a mine. This includes mine waste, rock, pyrites, slate, or other unmarketable materials which are separated during the cleaning process.
The face of exposed overburden or the face or bank on the uphill side of a contour strip mine excavation. The vertical wall consisting of the deposit being mined and the overlying rock and soil strata of the mining site.
A road built and used for transporting mined material by truck. The road can be from a mine head or pit to a loading dock, tipple ramp, or preparation plant.
Any surface entrance or opening related to an underground mine.
The last uncovered cut adjacent to the highwall. In surface mining the working area may be known as a strip pit. Mine workings or excavations open to the surface are also termed pits.
The overburden material removed in gaining access to a coal seam or mineral deposit.
Fine particle material from coal or mineral processing collected in a pond. Solid must be separated from the water in order to have clear effluent for reuse or discharge.
Surface expressions resulting from the caving in of underground mine voids. Slumps are differentiated from subsidence because they are normally in undeveloped areas. The area has infrequent public visitation, recreational use, farming, livestock use, etc. In all likelihood slumps will not cause loss of life, serious injury or economic loss.
Water leaving the AML PA and causing environmental impacts because of its pH, sediments load, or other pollutants, or because of its effect on other lands due to poor drainage conditions (i.e. agricultural flooding).
An AML area causing an environmental impact that does not fit one of the above definitions.
Section 403(b) Water Supplies Problems
Water supplies adversely affected by coal mining that are replaced through the repair, replacement, construction, or enhancement of facilities, including water distribution facilities and treatment plants.
Note: Individual or defined groups of water supplies that qualify as health and safety problems because of PWHC should be recorded as a Priority 1 or 2 as discussed above under the PWHC Problem Type.
