It seems pretty straight forward…do we even need a definition of “significant?”
“ i h i f◦ “…require a change in process safety information”
◦ Pretty broad definition. What constitutes a “change”?
Is any addition to PSI a change?Can you think of a change that is not “significant” but does change PSI?but does change PSI?
MOC process◦ Does your MOC form have a checkbox to
indicate whether or not the change requires PSSR?

Tolley – 1996What changes are significant enough to be◦ What changes are significant enough to be called a “new” facility?
…a "facility" means buildings, containers and equipment which contain a process. A facility constructed on a work site where there are no other facilities is considered a new facility.
d d ld b l bl " f l d…PSSR standard would be applicable to "new facilities and to modified facilities which contain a covered process", that is, a process in which (at any one point in time) there is a threshold quantity or great amount of a HHC.
