CHANGE IN I/C OPS PROCEDURE

1. It was agreed in the original I/C Ops Procedure to issue W/O's so that
no drum ran in the same position more than four runs. This was done to
reduce reruns necessary in the case of a drum short. Evidence indicates
that recently some I/C Ops have run the maximum of 12 W/O's with a drum in
the same position. This practise will be discontinued immediately. A
maximum of six runs instead of four is authorized with the drum in the same
position, I/C Ops will issue W/O's accordingly.

2. Effective immediately a new column will be entered in the
Controller's Log Book for entering W/O's rerun on each job for each
machine. The information will be taken from the Job Sheet and will be the
number of W/O's that have to be rerun for that machine. For example, on a
three bank job, reruns will be determined as follows:

Entry will be the number of W/O's marked RR, four in this case, and not the
number of runs involved. If a machine is stripped and short tested, and
shorts are found, the number of W/O's to be rerun is authorized at the
bottom of the sheet by the technician. If these W/O's are run on another
machine that has not stripped yet, the number of W/O's involved will be
included in the "W/O's RR" total for the machine with the short. In case
the W/O's have to be phoned to B.P., so as to be rerun at a later date,
they will not be included in "W/O's RR" total since the job may come up.

3. After all I/C Ops have read and initialed this notice, it will be
filed in the Work Notice Book for future reference.
