As used in this chapter: "Area of regional significance" means an area designated by the State Mining and Geology Board, pursuant to
Public Resources Code 2790, which is known to contain a deposit of minerals, the extraction of which is judged to be of prime importance in meeting future needs for minerals in a particular region of the state within which the minerals are located and which, if prematurely developed for alternate incompatible land uses, could result in the permanent loss of minerals that are of more than local significance.
"Area of statewide significance"means an area designated by the State Mining and Geology Board, pursuant to PRC Section 2790, which is known to contain a deposit of minerals, the extraction of which is judged to be of prime importance in meeting future needs for minerals in the state and which, if prematurely developed for alternate incompatible land uses, could result in the permanent loss of minerals that are of more than local or regional significance.
"Exploration" or "prospecting"means that search for minerals by geological, geophysical, geochemical and other techniques, including, but not limited to, sampling, assaying, drilling, or any surface or underground works needed to determine the type, intent, or quantity of minerals present in total amounts of less than one thousand cubic yards in any one location of one acre or less.
"Idle"means to curtail for a period of one year or more surface mining operations by more than ninety percent of the operation's previous maximum annual mineral production, with the intent to resume those surface mining operations at a future date.
"Interim management plan"is the plan which the operator of an idle mine shall submit in accordance with PRC 2770 (h) (1) to (i) and gain approval for, in order to assure that the site shall be maintained in compliance with the approved reclamation plan, use permit, and applicable conditions, until the mine operation is resumed or the mine is fully reclaimed in accordance with the approved reclamation plan.
Intermittent Operation. A surface mine that is operated only periodically, where one or more years of inactivity between operating periods may occur because needs for the minerals produced at such mine maybe supplied from stockpiles, market conditions may require only an intermittent supply of these minerals, or physical conditions may preclude continuous operations. An example of the latter could be the natural buildup of a gravel bar in a stream or river. Intermittent operations must be identified in the determination of vested rights, use permit, and/or reclamation plan.
"Mined lands"includes the surface, subsurface, and groundwater of an area in which surface mining operations will be, are being, or have been conducted, including private ways and roads appurtenant to any such area, land excavations, workings, mining waste, 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 located.
"Minerals"means any naturally occurring chemical element or compound, or groups of elements and compounds, formed from inorganic processes and organic substances, including, but not limited to, coal, peat, and bituminous rock, but excluding geothermal resources, natural gas, and petroleum.
"Mining waste"includes the residual of soil, rock, mineral, liquid, vegetation, equipment, machines, tools, or other materials or property directly resulting from, or displaced by, surface mining operations, excluding stockpiles as defined in this chapter.
"Operator"means any individual, firm, association, corporation, organization, or partnership, or any city, county, district, or the state or any department or agency thereof who is engaged in surface mining operations himself, or who contracts with others to conduct operations on his behalf, except a person who is engaged in surface mining operations as an employee with wages as his sole compensation.
"Overburden"means soil, rock, or other materials that lie above a natural mineral deposit or in between deposits, before or after their removal by surface mining operations. "Reclamation" means the combined process of land treatment that minimizes water degradation, air pollution, damage to aquatic or wildlife habitat, flooding, erosion, and other adverse effects from surface mining operations, including adverse surface effects incidental to underground mines, so that mined lands are reclaimed to a usable condition which is readily adaptable for alternate land uses and create no danger to public health or safety. The process may extend to affected lands surrounding mined lands, and may require backfilling, grading, resoiling, revegetation, soil compaction, stabilization, or other measures.
"Reclamation plan"means the plan required by the Surface Mining and Reclamation Act of 1975, and meeting all the requirements thereof, administrative guidelines and regulations adopted pursuant thereto,
Public Resources Code 21000 et seq. ("CEQA"), and ordinances of Amador County adopted in accordance therewith.
"Stockpile"means a volume of stored mined material which is residual or secondary material extracted during a surface mining operation and which has a demonstrated future economic value sufficient to warrant its protection and preservation.
"Surface mining operations"means all, or any part of, the process involved in the mining of minerals on mined lands by removing overburden and mining directly from the mineral deposits, open-pit mining of minerals naturally exposed, mining by the auger methods, dredging and quarrying, borrow pitting, streambed skimming, segregation and stockpiling of mined materials (and recovery of the same) or surface work incident to an underground mine. Surface mining operations include, but are not limited to:
1. In place distillation, retorting or leaching;
2. The producing and disposal of mining wastes;
3. Prospecting and exploratory activities.
