Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule defines terms used in 10 CSR
				  45.
(1) The terms defined in
				section
				444.352, RSMo Supp.
				1989 are incorporated by reference for use in 10 CSR 45.
(2) This section contains additional
				definitions of terms used in 10 CSR 45.
(A)
				Applicant. A person who applies for a permit from the department for a Metallic
				Minerals Waste Management Permit.
(B) Aquifer. A subsurface water-bearing bed
				or stratum of sand, gravel or bedrock which stores or transmits water in
				recoverable quantities that is presently being utilized or could be utilized as
				a water source for private or public use.
(C) Cave. A natural underground room or
				series of rooms and passages generally formed by solution of limestone large
				enough to be entered by a man.
(D)
				Cistern. An artificial reservoir or tank for storing water.
(E) Department. The Department of Natural
				Resources.
(F) Geological
				cross-section. A diagram or drawing that shows features transected by a
				vertical section drawn at an angle to the longer axis of geologic
				features.
(G) Geological features.
				Stratigraphic features, of both consolidated and unconsolidated geologic
				materials such as bedding, porosity, primary permeability, secondary
				permeability, and so forth, and structural features such as dips, folds,
				faults, joints, caves and fractures.
(H) Groundwater. Water occurring beneath the
				surface of the ground including underground watercourses, artesian basins,
				underground reservoirs and lakes, aquifers, other bodies of water located below
				the surface of the ground and water in the saturated zone.
(I) Karst. A terrain, generally underlain by
				limestone, in which the topography is chiefly formed by the dissolving of rock
				and which is commonly characterized by karren, closed depressions, subterranean
				drainage and caves.
(J) Metallic
				minerals waste management area boundary. The final planned outermost limits of
				the metallic minerals waste disposal areas or waste management areas as defined
				in section
				444.352(10),
				RSMo Supp. 1989. This boundary will identify and encompass the areas used to
				compute the required amount of financial assurance.
(K) Observable defect. Any defect which would
				be detectable by an experienced professional engineer making an on-site visual
				inspection of the dam in accordance with current engineering, geologic and
				construction practices. This includes, but is not limited to: slides, piping of
				fines, uncontrolled seepage that exists on the embankment or the downstream
				foundation of the dam, unusual zones of softness and irregular settlement,
				erosion on the upstream or downstream slope of the dam, spillways that are
				calculated to be inadequate for the design flood, spillways that are eroded or
				otherwise in poor condition and cracks in the embankment or
				structure.
(L) Owner. Any person
				who holds a fee simple title to the property upon which the metallic minerals
				waste disposal area is located.
(M)
				Permit. An enforceable authorization issued by the director of the Department
				of Natural Resources in accordance with the Metallic Minerals Waste Management
				Act, sections 444.352-444.380, RSMo Supp. 1989 collective with other
				environmental permits referenced in the Act.
(N) Slag. The refuse separated from metal
				during smelting.
(O) Slag pile. A
				body of slag deposited as a mound or pile for temporary or permanent
				storage.
(P) Stability. The
				properties of a dam or reservoir that cause it, when disturbed from a condition
				of equilibrium, to develop forces or moments that maintain
				equilibrium.
(Q) Standing water in
				wells. The static water level.
(R)
				Static water level. The distance measured from the established ground surface
				to the water surface in a well neither being pumped, nor under the influence of
				pumping, nor flowing under artesian pressure.
(S) Stream. Any body of running water moving
				under gravity flow in a clearly defined channel on the surface of the ground or
				in a subterranean cavern.
(T)
				Subsidence. The settling of the ground surface as a result of natural or
				man-made causes.
(U) Tailings. The
				material generated by a mining/milling operation which is deposited in slurry
				form in an impoundment for storage and/or disposal.
(V) Tailings dam. An existing dam or
				reservoir used for the impoundment or retention of tailings or a proposed,
				existing or newly constructed dam and reservoir for which the anticipated or
				contemplated use is the impoundment or retention of tailings.
(W) Waste management control structure. Any
				structure or device whose purpose is to contain, impound or otherwise control
				metallic minerals waste.
(X) Waste
				management dam. Any waste management control structure which extends across a
				stream or water-course which does or may impound metallic minerals
				wastes.
(Y) Watercourse. A valley,
				swale, depression or other low place in the topography which may be occupied by
				flowing water during conditions of runoff.
(Z) Water well. A well constructed when the
				intended use of that excavation is for the acquisition of groundwater
				supply.
