84.

What type of review method must be used to evaluate the impacts of changes on safety

and health? How many people must review each change situation?

DOE contractors may use a graded approach to develop the review method and authorization

procedure appropriate for each class of change in a covered process. The level of review

should be commensurate with the potential risk associated with the change. DOE contractors

should consider the degree to which the change introduces new potential hazards or affects

safety-critical systems or components.

85.

Are any types of changes on or around a covered process (e.g., changes to safety showers,

catwalks, structural steel) intended to be excluded from MOC requirements?

DOE contractors should decide what types of facility changes, excluding replacement-in-kind,

to covered under the MOC system. Contractors should use caution in simply dismissing any

broadly defined class of change because no apparent safety and health impacts can be seen on a

generic basis.

What does necessary time period for change mean?

86.

Used in conjunction with temporary changes, it means the time that the change is allowed to

exist without undergoing further review.
