General Maintenance. General maintenance includes
all maintenance that is routine in nature and which does not

Included under general

component inspections, cleaning, sampling of oil and air, and
General maintenance consists of two sub-elements which are
addressed in detail under Section 3 of this chapter:
Repairs are maintenance actions which
require the fabrication of piping or components, and for which
there is no deviation from the original design.
repairs are actions such as:
replacement of piping, component
replacement involving welding, machining of parts or components,
cladding, stud replacement and weld repairs. It is emphasized that
repairs do not involve deviation from the original design.
Therefore, the replacement of a valve with the valve of a different
manufacturer which meets the original design specifications,
constitutes a repair.
Should the replacement valve not meet the
original design specifications, or should such specifications not
exist as is the case with some older facilities, then the valve
change would be treated as an alteration.
