2.0 ACTIVITIES UNDERTAKEN IN 2001

2.1 Safety and EnvironmentalNo safety or environmental incidents occurred on this pipeline system in 2001.

2.2 Maintenance PerformanceIn 2001, 84 Maintenance Work Orders were produced from Epic Energy’s ComputerisedMaintenance Management System (Maximo), made up as follows:

• 59% Preventative Maintenance tasks; and• 41% Corrective Maintenance tasks.

2.2.1 Pipeline

• All scheduled routine pipeline roadpatrols and inspections of aboveground facilities were completed asper Licence requirements.

• Fire extinguisher inspections andmaintenance were completed inaccordance with Australian Standards.

• MLV servicing, pig trap vessel andvalve maintenance were completed asscheduled.

• Filter Inspections / maintenance werecompleted as scheduled

• Remediation work completed as aresult of a pipeline risk assessment.70 additional “Pipeline Warning“ signswere installed.

2.2.2 Cathodic Protection

Differential Voltage Test Post Construction of

Nangwarry.

• The effectiveness of the cathodicprotection system is monitored bycarrying out two full line potentialsurveys annually, once at the end ofwinter and then at the end of summer.In addition all cathodic protection units(CPU’s) are inspected for correctoperation bi-monthly.

• Survey results indicate all areas of thepipeline system met the targetperformance levels of protection).

• Due to the small current demand onthe Safries and the South EastPipelines, they are protected withsacrificial anode systems.


-10-

2.2.3 Electrical & Instrumentation

• Accuracy Verification Testing is carriedout at all sites two-monthly inaccordance with customeragreements.

• Various corrective maintenance issueswere addressed:

Low battery volts at several sites,Low pressure alarms at severalsites,Replacement of turbine meters,Faulty transmitters at several sites.

• The Daniel Solar Flow computerswere replaced at all sites with Fisherremote operation controllers [models312 & 364]

2.2.4 Communications

• The communications system for the South East Pipeline system has beenchanged as part of the flow computer upgrade work. The communication systemis a direct link with the Telstra digital system giving “Real Time“ data, replacing theold dial up facilities.

• Several communication faults needed to be addressed, directly associated withthe new modems and Telstra link.

2.2.5 Mechanical

• All scheduled routine dust filterinspections/changes, relief valvetesting, MLV maintenance, regulatorinspection/services, Coalescer filterinspection/changes and ESD valveoperational checks were completed asper the Maintenance Plan.

• Corrective maintenance consisted ofmainly regulator failures and blockedpipe strainers.

2.2.6 Other

2.2.6.1 Landholder Contacts

There are five landowners and occupiers along the Safries Pipeline, 75 landownersand occupiers along the South East Pipeline, and 12 landowners on the Nangwarrylateral.

A property owner contact scheme is operated by Epic, and the Epic property officerpersonally visits each owner or occupier along the pipeline system at least onceannually.


-11-

Other contacts are made by Field Maintenance Officers, Local Contractor andSuperintendents during the course of daily business, or other land related issues thatarise occasionally are recorded in our Land Management System.

Land Management is supported by dedicated LMS software that provides a powerfuldatabase and MapInfo facilities All property details, and notes relating to discussions orissues with the property owners are recorded in the LMS. Through its MapInfo facilityan image of the cadastral boundaries of each property relative to the pipeline route canbe displayed for any property. During the year each property owner dwelling has beencaptured by GPS and will be displayed on the pipeline / cadastral plans.

If personal contact cannot be made, letter or telephone contact is made with theoccupier or owner. A letter explaining the reason for the visit, the contact officer’sbusiness card, an information brochure on pipeline safety and our dial before you digcontact phone number is left at all unattended residences visited. All property ownersreceive our pipeline safety brochure, a complimentary biro, as well as a high qualitycalendar, which is individually mailed out.

These items all contain our "Dial Before You Dig" contact phone number andstrongly reinforce safe working practices near high-pressure gas lines.

A file is maintained for each of the land parcels crossed by pipelines. Each property isflagged with the Land Titles Office who inform Epic of any changes in ownership orland tenure details, ensuring that our records are always up to date for mail outs andpersonal visits.

2.2.6.2 Pipeline Location Service

Epic Energy provides a free service to locate pipelines for which they are responsible.This service is primarily used by other companies carrying out civil works in the vicinityof any of the pipelines administered by Epic Energy.

There were 10 actual pipe locations carried out for third parties on the South EastPipeline system in 2001. The locations required Epic Energy supervision for thirdparty activity within the pipeline easement, mainly for new and replacement fences andvehicles working within the easement boundaries.


-12-

2.2.6.3 Community Awareness

Epic Energy implements a CommunityAwareness Program, that entails holdingawareness meetings with communitiesalong the pipeline route.

The target is to hold meetingsapproximately monthly with CFS, MFS,police, ambulance, SES, councils, EarthMoving Contractors, irrigation installationcontractors and various communitymembers invited to attend.

In year 2001, one public awarenesspresentations for the South East PipelineSystem was made at Mount Gambier. Thefocus of the presentation was on thespecific nature and characteristics of theproducts carried by the South EastPipeline System line, the route of thepipeline, basic information about thepipeline and its monitoring, control andemergency procedures.

2.3 TrainingConsiderable training was carried out in SA for field maintenance personnel, including:

• Base Line (Petroleum Industry) training was completed by all Epic Energy field personnel;

• Senior First Aid Training (re-certification) was completed by all field staff;

• Heath, Safety and Environmental (HSE) Induction training was completed by all EpicEnergy field personnel;

• Permit to Work training was completed by all Epic Energy field personnel;

• Dr Hassan Nabi-Zadeh (Epic Energy Corrosion Control Engineer) conducted in houseCathodic Protection training;

• Pipeline Location training in the use of Metrotech 9800 series Pipeline Locators wasconducted by Corepro Pty Ltd;

• In house on the job training has been achieved for various field staff in the conduct of:• Relief Valve Testing• Regulator Maintenance• AVT inspections• Filter Vessel inspection and Filter change procedure.• Cathodic protection (full line surveys and transformer rectifier surveys)


-13-

2.4 Emergency ResponseNo emergency response drills were scheduled and/or conducted on the South East PipelineSystem 2001.

Pipeline Licences 3 & 4 require reports on emergency drills be held on each pipeline systemat least every 2 years. The next Pipeline Emergency Response exercise scheduled for theSouth East Pipeline system is in March 2002.

3.0 COMPLIANCE ISSUES

Every endeavor is made to ensure that design, manufacture, construction, operation,maintenance and testing of all appropriate facilities are carried out in accordance with AS2885. Any non-compliance identified is logged in Epic Energy’s Computerised MaintenanceManagement System, where they are tracked to conclusion. Significant items are reporteddirectly to PIRSA.

A copy of the currently gazetted Statement of Environmental Objectives (SEO’s) for PL3 andPL4 are provided at Annexes A and B respectively. The overall objectives of the SEO’s wereachieved in that:

• Environmental damage from activities involved in operation of the South East Pipeline wasminimised;

• Appropriate consultative processes involving people directly affected by regulated activitiesand the public generally were established; and

• The public was protected from risks inherent in regulated activities involving the South EastPipeline.

The specific objectives declared in the SEO’s have been assessed in accordance with theGoal Attainment Scaling. The results of that assessment are provided in Annex C.

4.0 ACTIONS TO RECTIFY NON-COMPLIANCETo mitigate corrosion, all buried pipelines are covered with a protective coating which servesto isolate the external pipeline surfaces from corrosive elements in the surroundingenvironment. Secondary protection at coating holidays and imperfections is achieved byapplying cathodic protection.


-14-

The effectiveness of the cathodic protection system is monitored by carrying out two full linepotential surveys annually, once at the end of winter and then at the end of summer. Inaddition all cathodic protection units (CPU’s) are inspected for correct operation bi-monthly.

Survey results given in Annex D indicate all areas of the pipeline system met the targetperformance levels of protection. One test point at Km 1.4 on Kimberley Clarke pipe shows -0.740 mV. This potential belongs to the foreign pipe crossing Kimberley Clarke line at that testpoint.

5.0 MANAGEMENT SYSTEM AUDITS

5.1 Operational AuditsEpic Energy is partially owned by El Paso Corporation, a major North American gastransmission company. The El Paso Corporate Audit Division conducted an operational auditon Epic Energy in the third quarter of 2001. Results of that audit were very favourable andEpic Energy is now being used as a model for El Paso’s other assets in North America.

5.2 Environmental AuditsWhilst no external audit per se was carried out during the year, internal processes includingground patrols and landowner contact provided a complete coverage of the environmentalstatus of the PL3/4 system.

In 2001 each property on the PL3/4 System was visited by our Environment and LandManagement Officer. The officer spoke to each landholder regarding pipeline safety andenvironmental issues. At each meeting, landholders were asked to comment on any issuesrelating to the operation of the pipeline through their land.

Any area of concern or special requirement, such as conditions of entry could then becaptured on GPS, and recorded on the Epic Energy Land Management System (LMS).

Nangwarry Lateral

Reinstatement work is still being funded on one property, used for fine wool production, at KP4.4 on the Nangwarry Lateral. Approximately 600 metres of the Right Of Way are beingfenced off and resown with pasture grasses at an approximate cost to Epic Energy of $4,000.It was found that after reinstatement, the sheep in the pasture were attracted to the sweeterregrowth and grazed it so heavily that it did not survive. Bare patches developed that wereused by the sheep as wallow pits, further degrading the remaining pasture.

An existing invasive weed on the property “Cape Weed” colonised the degraded areas,compounding the situation. Initial reinstatement work provided a good pasture seed bed, thatif this chain of events had not occurred, would have matured into satisfactory pasture.

The landowner provided a reinstatement signoff at completion of the job and only made EpicEnergy aware of the situation when asked to sign the grant of easement document.

5.3 Safety AuditsEpic Energy has developed and implemented a Safety Management System (SMS) for alloperations and pipeline systems. An internal audit of the SMS was conducted in 2001.Further to this an external review was undertaken by Det Norske Veritas (DNV) in accordancewith our Western Australia Safety Case requirements.

Housekeeping inspections are conducted monthly at all facilities in accordance with our SMSrequirements.

6.0 REPORTS GENERATED IN 2001The following report was generated and forward to PIRSA during 2001:

• PL3/4 Annual Report for 2000 compiled in March 2001, forwarded 11 April 2001.

7.0 REPORTED INCIDENTSThere was one reported operational incident on the Safries Lateral in 2001. The AL 5000diaphragm meter at the Safries delivery point failed and restricted the supply of gas to thecustomer. A mechanical failure within the meter caused a section of the valve assembly todislodge, restricting the flow of gas. The Epic Energy contractor responded and by-passedthe meter to reinstate customer flow until a suitable replacement meter was installed.

8.0 THREATS TO THE PIPELINEAn AS2885 Risk Assessment was conducted on the South East Pipeline in July 2001, usingan external facilitator. Since conducting that work, Epic Energy has made the transition tofacilitating such workshops using internal resources. This has returned very positivedividends and established a new bench mark for the conduct of Risk Assessments withinEpic Energy. As such, it is intended to treat the 2001 Risk Assessment as a preliminary toolto ensure the safety and integrity of our operations are maintained at a high standard. TheRisk Assessment will be repeated in its entirety during the second half of 2002.

Notwithstanding the intention to repeat the AS2885 Risk Assessment, it is important to notethat the Workshop was determined to be successful in that:

• The desired objectives were generally achieved;

• It identified the need for seventy additional signs to be installed and letters forwarded toeach of the landowner emphasising the importance of warning markers;

• All personnel involved in the Risk Assessment Study gained a greater appreciation of thefacilities and the need for the conduct of such studies; and

• Free and open discussion took place during the workshop to ensure all hazards andoperability problems were identified and actions were developed to mitigate these to anacceptable level.

9.0 OPERATIONS PROPOSED FOR 2002/2003Considerable work is scheduled for 2002/2003 including:

• Several excavations of the pipeline system to inspect the integrity of the “Zaplock“ jointingsystem implemented during construction and the “Canusa“ shrink sleeve coating of thejoints;

• Blasting and painting of the above ground facilities, including meter stations, and pig trapand MLV sites; and

• Two projects have been approved to replace obsolete and antiquated equipment, andreplace carbon steel fittings with stainless steel fittings.

10.0 VOLUME OF PRODUCT TRANSPORTEDApproximately 2,755 TJ of natural gas were transported through the South East Pipeline in2001.

1 INTRODUCTION

This Statement of Environmental Objectives (SEO) has been prepared in accordancewith the requirements of Section 99 of the Petroleum Act 2000.

Licence Pipeline Licence 3

Licence description Katnook to Safries Lateral Pipeline

Location Refer to Figure 1.

Activities covered by thisCEP/SEO.

All regulated activities relating to the operation of the Katnook to SafriesLateral Pipeline.

This SEO does not apply to de-commissioning of the pipeline. A separateSEO will be required prior to de-commissioning.

This SEO does not apply to pipeline construction projects.

The objectives developed in this SEO are in keeping with the objectives of thePetroleum Act 2000, which include:

� To minimise the environmental damage from the activities involved in theconstruction or operation of transmission pipelines for transporting petroleum;

� To establish appropriate consultative processes involving people directly affected byregulated activities and the public generally;

� To protect the public from risks inherent in regulated activities.

This document is based on Statements of Environmental Objectives/Codes ofEnvironmental Practice (SEO/CEP) developed for the following recent pipelineprojects:

� Pipeline Licence No 1 – Moomba to Adelaide Pipeline Looping Project

� Pipeline Licence No 4 – South East Pipeline – Nangwarry Lateral Project

In each case, the SEO/CEP was developed in accordance with both the existinglegislation (Petroleum Act 1940) and the proposed legislation (Petroleum Bill 1999).This included an assessment of the projects in accordance with the SignificanceAssessment Criteria (PIRSA 1999), and in each case the proposals were as being ofLOW environmental significance.

This SEO also takes account of previous Declarations of Environmental Factors andCodes of Environmental Practice approved under the Petroleum Act 1940, and makesreference to the Australian Pipeline Industry Association Code of EnvironmentalPractice : Part B – Onshore Pipeline Operations.

It should be noted that the major environmental impacts associated with a pipelineproject are associated with construction, while operational impacts are negligible incomparison. As stated above, this SEO applies to pipeline operations only.

1 INTRODUCTION

This Statement of Environmental Objectives (SEO) has been prepared in accordancewith the requirements of Section 99 of the Petroleum Act 2000.

Licence Pipeline Licence 4

Licence description South East Pipeline

Location Refer to Figure 1.

Activities covered by thisCEP/SEO.

All regulated activities relating to the operation of the South East Pipeline.

This SEO does not apply to de-commissioning of the pipeline. A separateSEO will be required prior to de-commissioning.

This SEO does not apply to pipeline construction projects.

The objectives developed in this SEO are in keeping with the objectives of thePetroleum Act 2000, which include:

� To minimise the environmental damage from the activities involved in theconstruction or operation of transmission pipelines for transporting petroleum;

� To establish appropriate consultative processes involving people directly affected byregulated activities and the public generally;

� To protect the public from risks inherent in regulated activities.

This document is based on Statements of Environmental Objectives/Codes ofEnvironmental Practice (SEO/CEP) developed for the following recent pipelineprojects:

� Pipeline Licence No 1 – Moomba to Adelaide Pipeline Looping Project

� Pipeline Licence No 4 – South East Pipeline – Nangwarry Lateral Project

In each case, the SEO/CEP was developed in accordance with both the existinglegislation (Petroleum Act 1940) and the proposed legislation (Petroleum Bill 1999).This included an assessment of the projects in accordance with the SignificanceAssessment Criteria (PIRSA 1999), and in each case the proposals were as being ofLOW environmental significance.

This SEO also takes account of previous Declarations of Environmental Factors andCodes of Environmental Practice approved under the Petroleum Act 1940, and makesreference to the Australian Pipeline Industry Association Code of EnvironmentalPractice : Part B – Onshore Pipeline Operations.

It should be noted that the major environmental impacts associated with a pipelineproject are associated with construction, while operational impacts are negligible incomparison. As stated above, this SEO applies to pipeline operations only.

2 OBJECTIVES

OBJECTIVE GOAL(S)

1. To avoid significant disturbance tolanduse or damage to infrastructure.

1.1 To minimise disturbance to landuse anddamage to infrastructure


3. To promote and maintain vegetationcover on the ROW.


3.2 To maintain regrowth of native vegetation



5.1 To ensure that uncontrolled emissions arereported and acted upon immediately

6. To minimise the risks to public andthird party health and safety.

6.1 To adequately protect public and thirdparty safety during normal operation.


6.3 To adequately protect public and thirdparty safety during maintenance.

7. To ensure the environmentalmanagement and rehabilitation of dig-ups is carried out in accordance withthe APIA Code of EnvironmentalPractice Part B – Onshore PipelineOperations.

7.1 To minimise the impact as a result of anemergency situation, incident oroperational dig up.

8. To ensure security of supply for usersof natural gas.

8.1 Minimise the likelihood of any significantcurtailment of gas supply to customer(s)which could result in a detrimental impacton gas supply to a significant number ofgas users in South Australia.

8.2 Maintain a prudent level of gas supply tocomply with contractual obligations.


3 ASSESSMENT CRITERIA

The objectives identified above are subject to an assessment to measure the level ofachievement. The assessment criteria for each objective will be one of the following:

� Defined conditions - objectives for construction and operation activities that can onlybe managed through the prevention of unacceptable actions (e.g. no remnantvegetation shall be cleared);

� Defined requirements - the achievement of an objective can be assessed againstthe implementation of specific procedures or actions required for an activity (e.g. thedesign and construction of the pipeline must meet the requirements of AS 2885.1—1997 Pipelines—Gas and liquid petroleum);

� Goal Attainment Scaling (GAS) criteria - the objectives are assessed against a setcriteria to determine the level of goal achievement (i.e. goal exceeded, achieved ornot achieved).

Appendix A tabulates the objectives and the appropriate assessment criteria. The GAScriteria is detailed in Appendix B.


4 REPORTING REQUIREMENTS

� A Ministerial direction to effect gas supply rationing.

Reportable Incidents

The incidents listed below are considered to be reportable incidents under Section85(1) of the Petroleum Act 2000:

� Unauthorised activity on the pipeline easement where the pipeline is not contacted.

� Oil or hazardous material spill that adversely impacts on an area not specificallydesigned to contain such spills.

� A less than the prudent level of gas being supplied to, or through, thesupply/transmission system for Epic to comply with its contractual obligations for aperiod greater than 12 hours.

A range of KPI’s are also required to be reported in the annual report.


REPORTING REQUIREMENTS

All incidents must be reported to the Epic Superintendent in accordance with Section6.2 of the Epic EMS Overview Manual.

In addition, the following external reporting requirements apply. It is the responsibilityof the Epic Superintendent to ensure that all incidents are reported and actionedappropriately.

Serious Incidents must be reported to the PIRSA Minister as soon as practicable afterthe occurrence, as per Section 85 of the Petroleum Act 2000 and Regulation 32 of thePetroleum Regulations 2000.

Reportable Incidents must be reported to PIRSA on a quarterly basis within 1 monthof the end of the quarter, as per Regulation 32 of the Petroleum Regulations 2000.

Annual Report must be reported to PIRSA within 2 months after the end of the licenceyear, as per Regulation 33 of the Petroleum Regulations 2000.
