Workshop Memorandum No. 18-059 Page 4 of 5

The existing mechanism components that are mounted to the existing tank concrete walls,
including the idler stub shafts (6 per tank, 18 total), head shaft spindles (2 per tank, 6 total),
and return track support wall bracket assemblies (34 per tank, 102 total), are in good
condition and do not require replacement. In addition, it is desired to leave the existing wall-
mounted components in place for re-use with the proposed equipment to avoid the potential
for costly and timely structural repairs to the existing concrete walls in the event that the
walls are damaged during removal and replacement of the components and associated wall
anchors. The proposed replacement equipment will need to perfectly mate with the existing
wall-mounted components proposed to be re-used to ensure proper and reliable operation
of the mechanisms, including location of the existing idler stub shafts, location of the existing
head shaft spindles, connection of the proposed idler sprockets and shaft bearings to the
existing idler stub shafts, connection of the proposed head shaft to the existing head shaft
spindles, and connection of the proposed return wear strips to the existing return tracks and
support wall bracket assemblies. Requiring the mechanisms to be manufactured by
Brentwood Industries/Polychem Systems will guarantee that the proposed equipment will
perfectly mate with the existing wall-mounted components to be re-used.
