As used in this chapter:
Removal of overburden and the mining of limited amounts of ores or mineral solids are not considered mining when done only for the purpose of determining location, quantity, or quality of a natural deposit if no ores or mineral solids removed during exploratory excavation or mining are sold, processed for sale, or consumed in the regular operation of a business and if the affected land does not exceed two acres in area. Mining does not include plants engaged in processing minerals except as the plants are an integral on-site part of the removal of ores or mineral solids from natural deposits. Mining does not include excavation or grading when conducted solely in aid of on-site farming or of on-site construction. Mining does not include dredging operations where the operations are engaged in the harvesting of oysters, clams, or the removal of shells from coastal bottoms.
