"Contamination"means an impairment of the quality of the surface water and groundwater to a degree which creates a hazard to the public health through poisoning or through the spread of disease.
"Facility"means a building, processing plant, or other mining related permanent structure.
"Groundwater"means that part of the subsurface water which is in the saturated zone.
"Hard rock mining"means the removal of granite, limestone, or other dense rock formation by blasting, ripping or other similar methods.
"Highwall"means the unexcavated face of exposed overburden and ore in a surface mine.
"Idle mining operation"means a mining operation curtailed for a period of one year or more by more than 90 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"means a brief, written report prepared by the operator which provides measures the operator will implement to maintain the mining site in conformance with this chapter and the Surface Mining and Reclamation Act, including (without limitation), each approval issued pursuant thereto.

"Mining approval"means a land use approval authorizing a mining operation and reclamation thereof.
"Mining operation"means all, or any part, of the process involved in surface or subsurface extraction of minerals, including (without limitation), the removal of overburden and mining directly from the mineral deposits, open pit mining of minerals naturally exposed, mining by the auger method, hydraulic mining, quarrying and dredging, tunneling or surface work incident to an underground mine. Mining operations shall include (without limitation) in-place distillation, retorting, leaching, blasting, production, or disposal of mining waste products or by-products, mining products and overburden. Prospecting and/or exploring for one or more minerals, without other activities described above, does not constitute a mining operation.
"Mining operation review"means a review process for a mining operation to investigate compliance with mining approval, certificate of compliance, or reclamation plan approval conditions.
"Mining site or mined lands"means surface and subsurface and groundwater of areas in which a mining operation will be, is being, or has been conducted, including (without limitation): active mining areas, reclamation areas, drainage facilities, transportation routes within the limits of approved mining areas, storage and stockpile areas, areas for placement of overburden or mining waste, and areas in which land excavations, structures, facilities, equipment, machines, tools or other materials or property which result from, or are used in, the mining operation are located.
"Mining waste product or by-product"includes the residual of soil, rock, mineral, liquid, vegetation, equipment, machines, tools or other materials or property directly resulting from, or displaced by, mining operation, excluding overburden.
"Minor mining approval amendment"means minor change to a mining operation having no significant impact on the environment, which may include (without limitation), minor change in hours of operation, drainage pattern or operational equipment.
"Native species"means plant species indigenous to California, using Pre-European as the historic time reference.
"Noxious weeds"means any species of plant that is or is likely to become destructive or difficult to control or eradicate.
"Operator"means any person who is engaged in a mining operation, or who contracts with another to conduct an operation, except a person who is engaged in a mining operation as an employee with wages as sole compensation.
"Overburden"means soil, rock, or other materials that lie above a natural mineral deposit or in between mineral deposits, before or after their removal by a mining operation.
"Owner"means any person who has an ownership or leasehold interest in a mining site or mined lands.
"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 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 which 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 a plan meeting the specific requirements for reclamation pursuant to SCCC §
16.54.040, §
16.54.055 and §
16.54.101 providing for the reclamation of any lands affected by mining operations, as approved by the County.
"Reclamation plan approval"means a land use approval authorizing and requiring the reclamation of mined lands including the removal of all mining related structures and equipment which are not the subject of any existing or proposed mining operation in accordance with this chapter, the County General Plan, Local Coastal Plan, and zoning ordinance and the Surface Mining and Reclamation Act.
"Residual hazard"means a condition at a ceased, idle, or abandoned mining operation which is a threat to public health or safety, or the environment, or which constitutes a nuisance.
"Sand mining"means the removal of sand or other loose rock formation by scraping, bulldozing, dredging or other similar methods.
"Spring"means a place where groundwater flows naturally from a rock or soil onto the land surface or into a body of surface water.
"Topsoil"means the upper part of the soil profile that is relatively rich in humus.
