Western Australian Consolidated Regulations Western Australian Consolidated Regulations (1) Subject to
subregulation (2), the 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accident events, is outdated so that the safety case no longer adequately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 Division 2
Subdivisions 1, 2 and 3;
(b) the
operator proposes to modify or decommission the facility and the safety case
does not provide, or adequately provide, for the proposed modification or
decommissioning of the facility;
(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 for the
facility;
(e) the
activities to be carried out at the facility are different from the activities
contemplated in the safety case.
(2) If an operator of
a facility is required under subregulation (1) to submit a revised safety
case because there is proposed a significant change to, or decommissioning of,
the facility the operator must not submit the revised safety case before the
operator and the Safety Authority have agreed on the scope of any validation
required to be provided in respect 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 of part of the safety
case in force for the facility.
