What process will BLM follow in reviewing a modification of my plan of operations?

(a) BLM will review and approve a modification of your plan of operations in the same manner as it reviewed and approved your initial plan under §§ 3809.401 through 3809.420; or (b) BLM will accept a minor modification without formal approval if it is consistent with the approved plan of operations and does not constitute a substantive change that requires additional analysis under the National Environmental Policy Act.
