7.0 SCOPE OF WORKSHOP
The Workshop Scope undertaken was to perform an AS2885 Safety Management Study (SMS) Workshop and document the process for the proposed development at Brooklands Estate in Henley Brook.
This assessment was required to take into account the relevant section of the following existing operating Pipeline:
Parmelia Gas Pipeline (Operated by APA Group) (KP305.977 308.048)
As part of the SMS Workshop assessment, the following is required:
1. Review of the Location Classification for the above Pipeline taking into account the Proposed Works
2. Safety Management Study for the above Pipeline for the section in which the pipeline measurement length encompasses the Proposed Works (Location Specific and Non-Location Specific Threats)
The Safety Management Study is required to assess:
1. Threats to the Pipeline from proposed Construction activities 2. Any new threats which may exist from the proposed works (during Operations) 3. If current controls to existing threats are sufficient taking into account the proposed
works and any Location Class changes which may arise (Loc Specific and Non-Loc Specific Threats)
The above is a License and AS2885 requirement for the Parmelia Gas Pipeline.
The purpose of the Safety Management Study it to ensure the continued safe operation of the pipeline and safety of those in the surrounding area from the pipeline.
An initial Safety Management Study was performed in December of 2018 for Burgess Design Group. However, since then a new road crossing of the PGP as well as minor changes to the Structure Plan have been proposed. As such, a second workshop was performed in order to update the Safety Management Study accordingly against the revised Structure Plan.

3.0 SCOPE
The Scope of this Terms of Reference document is to outline the requirements for an AS2885 Safety Management Study (SMS) Workshop and document the process for the proposed Residential Subdivision Property Development Project at Brooklands Estate, in Henley Brook.
This SMS Workshop is required to take into account the relevant section of the following existing operating pipeline:
Parmelia Gas Pipeline (Operated by APA Group) (KP305.977 KP308.048)
As part of the SMS Workshop assessment, the following is required:
1. Review of the Location Classification for the above pipeline taking into account the Proposed Works
2. Safety Management Study for the above Pipeline for the section in which the pipeline measurement length encompasses the Proposed Works (Location Specific and Non-Location Specific Threats)
The Safety Management Study is required to assess:
1. Threats to the pipeline from proposed construction activities 2. Any new threats which may exist from the proposed works (during Operations) 3. If current controls to existing threats are sufficient taking into account the proposed
works and any Location Class changes which may arise
The above is a License and AS2885 requirement for the Parmelia Gas Pipeline.
The purpose of the Safety Management Study is to ensure the continued safe operation of the pipeline and safety of those in the surrounding area from the pipeline.
An initial Safety Management Study was performed in December of 2018 for Burgess Design Group (refer Workshop Report Doc No: R-BDG-1336). However, since then a new road crossing of the PGP as well as minor changes to the Structure Plan have been proposed. As such, a second workshop needs to be performed in order to update the Safety Management Study accordingly against the revised Structure Plan.
3.1 Excluded from Scope
The following items are excluded from the Scope:

Rev 0 TOR-JDSI-1469 14
Essentially the process will be as follows:
Present the pipeline details Conduct Location Classification Review “Walk” the line section via aerial photographs or similar (e.g. Photos of identified
features) and refer to the location classes as defined by the Location Classification Review
Employ AS2885 with regard to location sub-classes, signage requirements and minimum number of protection measures (physical and procedural)
Select first section and review landowners and activities Review / log non-location threats that are general to that section including parallel
threats. If the threat is credible, log external interference protection measures and other prevention measures as necessary
If necessary, proceed to risk assessment using the risk matrix from AS2885.6-2018 attached in Appendix A
Select “Location Specific Threats” and review / log threats and external interference protection measures and other prevention measures as necessary, and proceed to risk matrix assessment as necessary
Log recommendations where required. Assign to appropriate personnel in attendance at workshop and provide estimated target date for completion.
Where the Risk is deemed not acceptable or not “As Low as Reasonably Practical (ALARP)” apply further control measures and re-assess until residual risk is acceptable
Identify Major Accident Events (events which could cause multiple fatalities) Identify threats requiring a Formal ALARP Assessment (includes MAE Events and
Threats with Risk Levels of Intermediate or higher) Note: Where required Formal ALARP Assessments will be done as a separate
Scope of Work and is outside this Terms of Reference Repeat steps above for subsequent sections
NOTE 1: Typical threats will be risk assessed the first time they are encountered and then referenced (or copied) where they apply for subsequent typical threats
NOTE 2: Non-Location Threats include non-process threats to Pipeline including corrosion, intentional damage etc.

7.5 Reporting
The documentation to be submitted upon completion of the SMS Workshop consists of a Report containing:
A populated register of the threats identified in the workshop and their assessment A list of actions generated during the workshop A copy of or reference to the Logging Tool Worksheet used in the SMS The Location Class Review Results A list of any Major Accident Events identified An outline of the Methodology and Reference to the Terms of Reference
The Reporting Schedule is as outlined in Section 6.0.
7.6 Management of Actions
Upon completion of the final report, the Client will perform a review and prepare a proposed action plan. This will be submitted to the Pipeline Licensee in a timely manner along with the SMS report prepared in order to facilitate the management of the required actions.
Actions raised from the SMS will be implemented in the Client’s relevant Action Management System.
This will close out the SMS Project and allow management of the required actions to be taken as a separate project.

city for an extended time
(more than a few days)
Widespread societal impact such as loss of
supply to a major city for a short time (hours to days) or to a localized area for a longer time
Localized societal impact or short-
term supply interruption (hours)
Interruption or restriction of supply
but shortfall met from other sources
Intermediate Repeat threat identification and risk evaluation processes to verify the risk estimation; determine the accuracy and uncertainty of the
estimation. Where the risk rank is confirmed to be "intermediate", where reasonably practicable modify the threat, the frequency or the
consequence to reduce the risk rank to "low" or "negligible".
Where it is not reasonably practicable to reduce the risk rank to "low" or "negligible", action shall be taken to:
(a) remove threats, reduce frequencies and/or reduce severity of consequences to the extent practicable; and
(b) Formally demonstrate ALARP
For an in‐service pipeline, the reduction to "low" or "negligible" or demonstration of ALARP shall be completed as soon as possible. Risk
reduction or demonstration of ALARP should be completed within a few months.Low
Impact widespread; viability of
ecosystems or species affected; or
permanent major changes
Major impact well outside Pipeline
Corridor or site; or long-term severe
effects; or rectification difficult

Risk Rank Risk Treatment Actions
Extreme Modify the threat, the frequency or the consequences so that the risk rank is reduced to Intermediate or lower.
For an in‐service pipeline, the risk shall be reduced immediately.
High Modify the threat, the frequency or the consequences so that the risk rank is reduced to Intermediate or lower.
For an in‐service pipeline, the risk shall be reduced as soon as possible. Risk Reduction should be completed within a timescale of not more than
a few weeks.
Determine the management plan for the threat to prevent occurrence and to monitor changes that could affect the classification
Negligible Review at the next relevant SMS (for periodic operational review, Land Use Change, Encroachment, or change of operating conditions)

city for an extended time
(more than a few days)
Widespread societal impact such as loss of
supply to a major city for a short time (hours to days) or to a localized area for a longer time
Localized societal impact or short-
term supply interruption (hours)
Interruption or restriction of supply
but shortfall met from other sources
Intermediate Repeat threat identification and risk evaluation processes to verify the risk estimation; determine the accuracy and uncertainty of the
estimation. Where the risk rank is confirmed to be "intermediate", where reasonably practicable modify the threat, the frequency or the
consequence to reduce the risk rank to "low" or "negligible".
Where it is not reasonably practicable to reduce the risk rank to "low" or "negligible", action shall be taken to:
(a) remove threats, reduce frequencies and/or reduce severity of consequences to the extent practicable; and
(b) Formally demonstrate ALARP
For an in‐service pipeline, the reduction to "low" or "negligible" or demonstration of ALARP shall be completed as soon as possible. Risk
reduction or demonstration of ALARP should be completed within a few months.Low
Impact widespread; viability of
ecosystems or species affected; or
permanent major changes
Major impact well outside Pipeline
Corridor or site; or long-term severe
effects; or rectification difficult

Risk Rank Risk Treatment Actions
Extreme Modify the threat, the frequency or the consequences so that the risk rank is reduced to Intermediate or lower.
For an in‐service pipeline, the risk shall be reduced immediately.
High Modify the threat, the frequency or the consequences so that the risk rank is reduced to Intermediate or lower.
For an in‐service pipeline, the risk shall be reduced as soon as possible. Risk Reduction should be completed within a timescale of not more than
a few weeks.
Determine the management plan for the threat to prevent occurrence and to monitor changes that could affect the classification
Negligible Review at the next relevant SMS (for periodic operational review, Land Use Change, Encroachment, or change of operating conditions)
