        (a) 
         If you receive a decision or order issued under chapter II, subchapter B, you must appeal that decision or order to IBLA under  43 CFR part 4, subpart E to exhaust administrative remedies.
    
    
        
        (b) 
         This section does not apply if the Assistant Secretary for Land and Minerals Management or the IBLA makes a decision or order immediately effective notwithstanding an appeal.
