(d) In order to assure effective safeguards with respect to installation, operation, and maintenance, the State or local authority will be required to own (or control), the land, subsurface, or coal seams in instances such as the following:
- (1) If the objective of the project is to prevent or alleviate subsidence, the State or local authority shall have or acquire such subsurface and underground rights or interests in such coal seams or coal measures as may be required to assure the stability and continued existence of the project and to such an extent as will give reasonable assurance that the work will not be disturbed in the future.
- (2) If the objective of the project is to rehabilitate or reclaim strip-mined areas, the land shall be owned by the Federal, State, or local body of government. Such ownership shall comprise such mineral, subsurface and underground rights and interests as will assure that no further mining operations will be conducted upon or under the land in the future.
- (3) If the objective of the project is to seal abandoned open shafts, slopes, air holes and other mine openings to underground workings where public safety hazards exist, or to control or prevent erosion, water pollution, or discharge of harmful mine waters, the State shall have or acquire such right, title or interest in the lands as will assure the stability and continued existence of the project work.
- (4) The extent of ownership or control necessary shall be determined with respect to each individual project.
