3.18.010 - Purpose.

A. Mining is a pervasive use in the city with some seventeen pits ranging from fifty to four hundred fifty acres with permitted depths to two hundred seventy-five feet. Over eighty percent of the nonpublic land in the city is devoted to mining operations.

B. Mining impacts include, but are not limited to deterioration of streets and other public infrastructure facilities; degradation of air quality; public health and safety hazards; increased noise; slope stability and slope erosion problems; security and safety concerns; visual blight; water quality impacts; problems with sand and particulate matter; and loss of developable land for other uses.

C. The city charter in Article XIII provides that the city shall have the authority to level general and special mining, excavation and processing taxes as is authorized by general law. The charter further recites that mining imposes severe negative environmental impacts upon city residents, businesses, properties and visitors and provides that the city has authority to regulate the mitigation of negative environmental impacts imposed on the city by mining and processing operations.

D. The purpose of this chapter is to establish a comprehensive taxing scheme for mining operations, both to support the city's general governmental operations and to raise revenue for specified purposes to be placed in the Mining Impact Fund to study, analyze, monitor, regulate, administer, correct, remediate and mitigate mining impacts and to facilitate reclamation of mining pits.

E. The city is also occupied by a number of recycling operations whose effect on surrounding properties is similar to that of processing rock materials. Materials such as paper, plastic, rubber, metal, glass and concrete are imported to sites in the city where they are crushed, ground, shredded, separated, sorted, baled, packaged, reprocessed and recycled for sale. The city believes this activity should be taxed in a similar manner as the processing of rock materials.

F. Ultimately, it is the city's goal, as stated in the charter, that mining operations are so conducted as to be a good neighbor to persons residing or working in the city and that at such time as a mining use is discontinued, the property be restored to a usable condition which is readily adaptable to alternate land uses and will create no danger to public health or safety. It is the purpose of this chapter to facilitate these goals.
