  CHAPTER I--MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR
 
PART 44--RULES OF PRACTICE FOR PETITIONS FOR MODIFICATION OF MANDATORY SAFETY STANDARDS--Table of Contents
 
                  Subpart E--Effect of Initial Decision
 
Sec. 44.53  Amended modification.

    (a) The Administrator may propose to revise the terms and conditions 
of a granted modification by issuing an amended proposed decision and 
order, along with a statement of reasons for the amended proposed 
decision and order, when one or both of the following occurs:
    (1) A change in circumstances which originally supported the terms 
and conditions of the modification.
    (2) The Administrator determines that findings which originally 
supported the terms and conditions of the modification are no longer 
valid.
    (b) The Administrator's amended proposed decision and order shall be 
served upon all parties to the proceeding and shall become final upon 
the 30th day after service thereof, unless a request for hearing on the 
proposed amendments is filed under Sec. 44.14. If a request for hearing 
is filed, the amended proposed decision and order shall be subject to 
all procedures of subparts C through E of this part as if it were a 
proposed decision and order of the Administrator issued in accordance 
with Sec. 44.13. The original modification shall remain in effect until 
superseded by a final amended modification.
    (c) In cases where the original decision and order was based upon an 
alternative method of achieving the result of the standard, the amended 
decision and order shall at all times provide to miners at the mine at 
least the same measure of protection afforded to the miners at the mine 
by such standard. In cases where the original decision and order was 
based upon a diminution of safety to the miners resulting from 
application of the standard at such time, the amended decision and order

shall not reduce the protection afforded miners by the original decision 
and order.
