Where a Federal surface management agency other than the Bureau of Land Management administers limited areas overlying Federal coal within the boundaries of a comprehensive land use plan or land use analysis being prepared by the Bureau of Land Management, or where the Bureau of Land Management manages lands on which coal development may impact land units of other Federal agencies, the Bureau of Land Management shall consult with the other agency to jointly determine the acceptability for further consideration for leasing of the potentially impacted lands the other agency administers or lands managed by the Bureau of Land Management that may impact lands of another agency.
