Anytime that the annual production of a surface mining operation is reduced for a period of one year or more by more than ninety percent (90%) of its maximum annual mineral production within any of the last five (5) years during which an interim management plan has not been approved, then the operator shall submit an interim management plan to provide measures for maintaining the site until normal production is resumed. The interim management plan shall be considered an amendment to the approved reclamation plan, but not just cause to re-examine an approved reclamation plan and/or cause the plan to be subsequently amended. An interim management plan shall not be considered a project within the meaning of CEQA, pursuant to the exemption granted under Section 2770 of the Act. (§ 1, Ord. 1191, eff. September 5, 1996; as amended by Ord. 1518, eff. February 13, 2020)
