The operator shall submit to the Department, no later than September 1 following the end of each permit year, a map in a form approved by the Department showing the location of the pit or pits by section, township, range and county, with such other description as will identify the land which the operator has affected by mining during such permit year and has completed mining operations thereon, with a legend upon such map showing the number of acres of affected land. Such map shall also show in acres the extent of the reclamation accomplished on the affected land, including grading and revegetation efforts, as of the end of the permit year, and shall show by appropriate designation any deviation from the plan of reclamation filed under subsection (c) of Section 724 of this title and the reasons therefor.

Whenever an operator shall have completed all requirements under the provisions of this act¹ as to any affected land, he shall notify the Department thereof. If the Department determines that the operator has completed reclamation requirements and achieved results appropriate to the use for which the area was reclaimed, the Department shall release the operator from further obligations regarding such affected land and the penalty of the bond shall be reduced proportionately.
