Section 211.5230  Process Unit Shutdown

"Process unit shutdown" means a work practice or operational procedure that stops production from a process unit or part of a process unit.  An unscheduled work practice or operational procedure that stops production from a process unit or part of a process unit for less than 24 hours is not a process unit shutdown.  The use of spare equipment and components and technically feasible bypassing of equipment and components without stopping production is not a process unit shutdown.
