OAR 632-033-0035: Modification of an Exploration Permit

Modification of a permit may be initiated at any time by the permittee or by the department. An Exploration Permit may be modified by approval of the department after timely notice and opportunity for review if the Department determines that modification is needed to comply with existing laws, or to accommodate unforeseen developments which may affect the reclamation or drill hole abandonment plan as previously approved. Expansion of an operation beyond the original permit area, depth or significant intensification of activity shall require permit modification.
