17.13.050 OPERATION CATEGORIES

All mineral extraction and excavation operations shall be classified as one of the following categories: A. Commercial operations must be a minimum of five (5) acres in size, and are operations that supply materials to the public on a continual, long term basis. All commercial mineral extraction and excavation operations shall file an operations and progress report with the Planning Commission every three (3) years. The report will summarize activities in fulfillment of the requirements for excavation and rehabilitation in compliance with the rehabilitation plan previously submitted to the Planning Commission. The conditional use permit shall remain in effect until such time that full reclamation has been made on the site. B. Temporary mineral extraction and excavation operations and associated uses, which may include, but are not limited to, asphalt or concrete plants which are necessary to supply material for a specific project (i.e., road construction), or a minor extraction operation of less than five (5) acres. These operations shall be allowed within any zone of the County as a conditional use. These operations will have to operate under the same standards as a commercial operation; the termination of the specific project shall also terminate the conditional use permit and the use of the pit. Once the project is complete, the owner or operator shall begin closure and reclamation operations within six (6) months.
