No person who has obtained a vested right to conduct surface mining operations prior to January 1, 1976, shall be required to secure a permit pursuant to the provisions of this chapter as long as such vested right continues, provided, however, that no substantial changes are made in any such operation except in accordance with the provisions of this Chapter. Expenses incurred in obtaining the enactment of an ordinance in relation to a particular operation or the issuance of a permit shall not be deemed liabilities for work or materials.
A person who has obtained a vested right to conduct surface mining operations prior to January 1, 1976 shall submit to the City Planner (and receive within a reasonable period of time) approval of a Reclamation Plan for operations to be conducted after January 1, 1976, unless a Reclamation Plan was approved by the City prior to January 1, 1976, and the person submitting the plan has accepted responsibility for reclaiming the mined lands in accordance with the reclamation plan.
Nothing in this section shall be construed as requiring the filing of a Reclamation Plan for, or the reclamation of, mined lands on which surface mining operations were conducted prior to January 1, 1976.
