378.204 Applicability.—The provisions of this part apply to land subject to the mandatory reclamation obligation for the severance of solid mineral phosphate rock set forth in s. 211.32(1) and to those lands which are initially used after July 1, 1984, as a clay settling area or a dam for use with a clay settling area. Such provisions do not apply to acres disturbed by the severance of phosphate rock prior to July 1, 1975, and, therefore, do not affect the determination of whether lands disturbed by the severance of phosphate rock are subject to the mandatory reclamation obligation. This part shall not be construed as giving the department permitting authority over mining operations.
