Which of the following criteria would justify not performing a periodic review of operating procedures?

The correct answer is B because periodic review of operating procedures is required as long as the process is active or could be operated , but may not be necessary if the process has been indefinitely suspended or permanently taken out of service .

CCPS emphasizes that operating procedures must be kept current, accurate, and reviewed periodically to ensure safe operation. This requirement applies regardless of automation level, operator experience, or frequency of operation.

Option A is incorrect because even with a strong Management of Change (MOC) system, periodic reviews are still required to ensure procedures remain accurate and complete. MOC addresses changes, but not ongoing validation.

Options C , E , and F are incorrect because automation, infrequent operation, or low turnover do not eliminate the need for review. In fact, infrequent operations may increase risk , making accurate procedures even more critical.

Option D is incorrect because CCPS promotes best practices beyond regulatory minimums ; absence of a regulation does not justify skipping reviews.

Therefore, only when a process is no longer in service (Option B) can periodic procedure review be reasonably deferred, as there is no active operation requiring those procedures.
