Sec.  9.40  Supplementation or revision of plan of operations.

    (a) A proposal to supplement or revise an approved plan of 
operations may be made by either the operator or the Regional Director 
to adjust the plan to changed conditions or to address conditions not 
previously contemplated by notifying the appropriate party in writing of 
the proposed alteration and the justification therefore.
    (b) Any proposed supplementation or revision of a plan of operations 
initiated under paragraph (a) of this section by either party shall be 
reviewed and acted on by the Regional Director in accordance with Sec.  
9.37. If failure to implement proposed changes would not pose an 
immediate threat of significant injury to federally-owned or controlled 
lands or waters, the operator will be notified in writing sixty (60) 
days prior to the date such changes become effective, during which time 
the operator may submit comments on proposed changes. If failure to 
implement proposed changes would pose immediate threat of significant 
injury to federally-owned or controlled lands or waters, the provisions 
of Sec.  9.33(c) apply.
