South Australian Numbered Regulations South Australian Numbered Regulations71—Revision of a safety case because of a change of circumstances or
operations
(1) Subject to
subregulation (2), an operator of a facility for which a safety case is
in force must submit a revised safety case to the Safety Authority as soon as
practicable after the occurrence of any of the following circumstances:
(a) the
technical knowledge relied upon to formulate the safety case, including the
knowledge of systems for identifying hazards and evaluating risks of major
accident events, is outdated so that the safety case no longer adequately
provides for the matters mentioned in regulations 46 to 63;
(b) the
operator proposes to modify or decommission the facility and—
(i)
the safety case has not been accepted by the Safety
Authority for the modification or decommissioning stage in the life of the
facility; or
(ii)
the proposed modification or decommissioning is not
adequately addressed in the safety case;
(c)
there are reasonable grounds for believing that a series of proposed
modifications to the facility would result in a significant cumulative change
in the overall level of risk of major accident events;
(d) the
operator proposes to significantly change the safety management system that is
in force at the facility;
(e) the
activities to be carried out at the facility are different from the activities
contemplated in the safety case.
(2) If a circumstance
mentioned in subregulation (1) is satisfied because the operator proposes
to modify or decommission the facility the operator must not submit the
revised safety case before the operator and the Safety Authority have agreed
on the scope of the validation of the proposal.
(3) If the Safety
Authority agrees, the operator of a facility may submit a revised safety case
under subregulation (1) in the form of a revision to part of the safety
case in force for the facility.
