I 1.2 This procedure need not be performed sequentially, except for !
subsection 5.9 (Repacking a Valve Under Pressure). When performed, i steps listed under subsection 5.9 shall be performed sequentially. ,
1.2.1 Steps of this procedure may be performed concurrently at the discretion of the Foreman. '
1.2.2 This procedure may be used for troubleshooting and l maintenance activities if specific instructions identifying +
the steps to be performed are controlled by a service -
request in accordance with OPGP03-ZA-0090, (Work Process Program). 1 1.3 This procedure satisfies Significant Operating Experience Report t (SOER)83-009. Commitment regarding replacement of valve packing in l safety related valves.
