2.0 ACTIVITIES UNDERTAKEN IN 2001

2.1 Safety and Environmental

2.1.1 IncidentsThere were 30 Incidents reported for the MAP, consisting of:

• 16 Environmental (4 third party encroachments, 2 oil spills(minor/contained), 5 gas releases and 5 erosions);

• 4 Incidents causing injury (2 LTI, 1 MTI, 1 no medical treatment required);

• 8 Safety (3 hazards, 2 near misses, 3 incident); and

• Unavoidable vehicle incidents.

2.1.2 Risk AssessmentsAn AS2885 Risk Assessment was undertaken for the MAP, which included allMAP Laterals (Doc No: TEB-012-0007-01). The draft risk assessment reportwas submitted to PIRSA in December 2001 and the final revision provided inJanuary 2002.Following a review of the location and non-location specific threats to thepipeline, six categories were considered to be credible:

- Corrosion.- External Interference, including: excavation, trenching operations, hole

boring, core sampling and bore drilling, blasting, dam building, road works,HDD operations, quarrying, construction activities, vibration at railway(cased) crossing, maintenance of drains and failure of other pipelines(rupture).

- Operations and Maintenance Threats, including: exceeding MAOP, piggingoperations, incorrect operation of control equipment, bypass of logic andcontrol equipment, inadequate maintenance procedures, inaccurate testequipment and inadequate servicing of pipeline.

- Natural Events, including lightning, floods/inundations, movement of sanddunes, erosion, and flotation of pipeline and impact by floating objects.

- Intentional damage.- Other threats, including: powerline breakages, induced voltages and fault

current from parallel powerlines, anchorage, as well as casings shielding thepipeline from adequate Cathodic Protection.

Of those credible threats, existing protection was determined to be adequate for

the majority and they were consequently assessed as being at ALARP. Theremaining threats were then assessed and risk ranked as follows:

River bed level recovery since removalof previous walls higher than originalcrossing area

Water flow looking downstream

2.2 Maintenance PerformanceIn 2001, 2235 Maintenance Work Orders were produced from Epic Energy’sComputerised Maintenance Management System (Maximo), made up as follows:

• 47 % Preventative Maintenance tasks; and• 53 % Corrective Maintenance tasks.

2.2.1 Pipeline• All routine road and aerial patrols and

above ground facility inspections werecompeted as scheduled.

• Fire extinguisher services werecompleted twice at all facilities inaccordance with Australian Standards.

• MLV and scraper station valves weremaintained in accordance with theMaintenance Program.

• A new 200mm lateral andregulator/meter station wasconstructed and commissioned tosupply the Origin Energy QuarantinePower Station. Epic Energy isresponsible for the operation andmaintenance of those facilities.

A total of three hot taps were carried out on the pipeline system in 2001. A400mm hot tap was carried out on the 500mm diameter Loop Line for theofftake to the new Origin Energy Quarantine Power station. A 200mm hot tapwas carried out on the Angaston Lateral for the offtake to the new Amcor Glassfactory. Finally, a 550mm hot tap was carried out on the Moomba to AdelaidePipeline for the offtake to the new Hallet Power Station.The underground pipework at Compressor Station 6, between the units and theaftercoolers was excavated and inspected as part of the ongoing pipelineintegrity management plan.Approximately 700 new “Pipeline Warning“ signs were installed on the Moombato Adelaide Pipeline to increase line of sight and ensure full compliance withAS 2885.3. The sections between Moomba and Compressor Station 2,Compressor Stations 4 and 5, and Peterborough to Compressor Station 7 wereall upgraded.


-11 -

2.2.2 Cathodic Protection

To mitigate corrosion, all buriedpipelines are covered with aprotective coating which serves toisolate the external pipeline surfacesfrom corrosive elements in thesurrounding environment. Secondaryprotection at coating holidays andimperfections is achieved byapplying cathodic protection.

The effectiveness of the cathodic protection system is monitored by carrying outtwo full line potential surveys annually, once at the end of summer and thenagain at the end of winter. In addition, all cathodic protection units (CPU’s) areinspected for correct operation bi-monthly.Survey results given in Annex C indicate all areas of the pipeline system metthe target performance levels of protection (Refer to Section 13). It should benoted that some of the OFF potentials lower than -0.850 V are from foreigncrossings and do not belong to the MAP. Examples of these include thepotential of the casing in a cased crossing; potential of the foreign pipe and aTelecom shielded cable. Apart from these low points there are genuine lowpotentials on the line that are due to the condition of the coating and nature ofthe local ground. Each year new ground beds are installed to increase the levelof protective current available to the pipe. Through this practice, old groundbeds with increased resistance are also replaced with new ones. In Year 2001two new ground beds were installed at KP 294.66 and at KP 416. These groundbeds were activated very early in 2002.

2.2.3 Electrical & Instrumentation

• All routine Meter Station custodytransfer and Compressor Stationfuel gas accuracy verification testswere completed as per themaintenance plan.

• Compressor station andcompressor unit electrical serviceswere completed in line with themaintenance program.

• Fire and gas detection systemswere serviced in accordance withthe Australian Standard.


-12 -

Cooled recycle valves were installed into the pig trap kicker line pipework atCompressor Stations 1, 2, 4, and 6 to prevent the station shutting down on highdischarge temperature. This project has increased station and unit reliability.The Compressor Station unit valves were overhauled and the valve positionerreplaced with Fisher DVC controllers, increasing fuel efficiencies and unitreliability.Regular inspections and maintenance was performed on the 19Kv SWER lineand solar panel battery powered sites on the Moomba to Adelaide Pipelinesystem.

2.2.4 CommunicationsRoutine maintenance has ensured the reliability of the digital microwavesystem.VHF, UHF, and Telstra telephone communication systems are maintained inaccordance with the maintenance management plan.

2.2.5 Mechanical• Compressor Station 7 had the Centaur

turbine on unit “A” was upgraded toincrease horsepower from 4000 to4700 and increase pipeline capacity.The unit “A” boost compressor wasalso overhauled to increaseefficiencies at the station.

• All scheduled routine filter inspections/changes, MLV maintenance, regulatorinspection/services, relief valve testing,and ESD valve operational checkswere completed on meter andcompressor as scheduled.

The Gas Engine Alternator at Compressor Station 4 was overhauled / rebuiltand the 68D Alternators at Compressor Station 1, 2 and 3 had cooling systemupgrades completed to prevent high shut downs and increase station powerreliability.The Angaston Meter Station relief valve was replaced with a modulating typerelief valve system to reduce gas emissions to atmosphere in the event of aregulator failure or a relief valve operation.

2.2.6 Other

2.2.6.1 Landholder Contacts

There are 470 landowners and occupiers along the MAP system.

A property owner contact scheme is operated by Epic Energy. The LandManagement Officer personally visits each owner or occupier along the pipelinesystem annually.

Other contacts made by Field Maintenance Officers and Superintendents duringthe course of daily business, or other land related issues that arise occasionallyare recorded in our Land Management System.

Land Management is supported by dedicated LMS software that provides apowerful data base and MapInfo facilities. All property details and notesrelating to discussions or issues with the property owners are recorded in theLMS. Through its MapInfo facility an image of the cadastral boundaries of eachproperty relative to the pipeline route can be displayed for any property. Duringthe year each property owner dwelling has been captured by GPS and will bedisplayed on the pipeline / cadastral plans.

If personal contact cannot be made, the occupier or owner is telephoned ormailed a letter explaining the reason for the visit, the contact officer’s businesscard, an information brochure on pipeline safety and our dial before you digcontact phone number is left at all unattended residences visited. All propertyowners receive our pipeline safety brochure, a complimentary biro, as well as ahigh quality calendar, 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 hard file is maintained for each of the 1500 land parcels crossed by pipelines.Each property is flagged with the Land Titles Office who inform Epic Energy ofany changes in ownership or land tenure details, ensuring that our records arealways up to date for mail outs and personal visits.

2.2.6.2 Pipeline Location Service

Epic Energy provides a free service to locate pipelines for which they areresponsible. This service is primarily used by other companies carrying out civilworks in the vicinity of any of the pipelines administered by Epic Energy.There were 190 actual pipe locations carried out for third parties on theMoomba - Adelaide Pipeline in 2001. The majority of the pipeline locationsrequested were as a result of the “One Call“ system, they ranged from newinstallations crossing the pipeline, new fences as a result of subdivisions, andgeneral activities on the pipeline easement. All authorised activities within thepipeline easement are supervised by Epic Energy field officers to ensure thesafety and integrity of the pipeline.


-14 -

2.2.6.3 Community Awareness

• Epic Energy implements a CommunityAwareness Program, which entailsholding awareness meetings withcommunities along the pipeline route.

• The target is to hold meetingsapproximately annually with CFS,MFS, police, ambulance, SES,councils, Earth Moving Contractors,irrigation installation contractors andvarious community members invitedto attend.

In year 2001, 3 public awareness presentations for the Moomba to AdelaidePipeline were made at Burra, Peterborough, and Whyalla. The focus of thepresentation was on the specific nature and characteristics of the productscarried by the Moomba - Adelaide line, the route of the pipeline, basicinformation about the pipeline and its monitoring, control and emergencyprocedures. Additional meetings were held with several utilities, includingTelstra, Origin Energy and ETSA.

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 fieldpersonnel;

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

• Health, Safety and Environmental (HSE) Induction training was completed by allEpic Energy field personnel;

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

• Pipeline Location training in the use of Metrotech 9800 series Pipeline Locatorswas conducted by Corrpro Pty Ltd;

• Confined Space Entry and the use of Breathing Apparatus Course wasconducted by BOC Gases Pty Ltd;


-15 -

• Wasleys Compressor Package training was conducted by Collicutt Pty Ltd(Canada, supplier of Package); and

• Familiarisation training in the maintenance of Gorter and Pietro Fiorentiniregulators was conducted by the suppliers.

2.4 Emergency ResponsePipeline Licence 1 requires emergency drills be held on the pipeline system at leastevery two years.

An emergency exercise was held at Angaston Compressor site on 15 February 2001.The exercise was used as a joint exercise for the Riverland Pipeline system and theAngaston Lateral under Pipeline Licence 1.

A full mobilisation exercise is scheduled for the Moomba to Adelaide Pipeline in 2002.

3.0 COMPLIANCE ISSUESEvery endeavour is made to ensure that design, manufacture, construction, operation,maintenance and testing of all appropriate facilities are carried out in accordance withAS 2885. Any non-compliance identified is logged in Epic Energy’s ComputerisedMaintenance Management System, where they are tracked to conclusion. Significantitems are reported to PIRSA.A copy of the currently gazetted Statement of Environmental Objectives (SEO’s) forPL1 is provided at Annex A. The overall objectives of the SEO’s were achieved in that:

• Environmental damage from activities involved in operation of the Moomba toAdelaide Pipeline was minimised;

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

• The public was protected from risks inherent in regulated activities involving theMoomba to Adelaide Pipeline.

The specific objectives declared in the SEO’s have been assessed in accordance withthe Goal Attainment Scaling. The results of that assessment are provided in Annex B.


-16 -

4.0 ACTIONS TO RECTIFY NON-COMPLIANCETo mitigate corrosion, all buried pipelines are covered with a protective coating whichserves to isolate the external pipeline surfaces from corrosive elements in thesurrounding environment. Secondary protection at coating holidays and imperfectionsis achieved by applying cathodic protection.

The effectiveness of the cathodic protection system is monitored by carrying out twofull line potential surveys annually, once at the end of winter and then at the end ofsummer. In addition all cathodic protection units (CPU’s) are inspected for correctoperation bimonthly.

Survey results given in Appendix C indicate all areas of the pipeline system met thetarget performance levels of protection. It should be noted that some of the OFFpotentials lower than -0.850V are from foreign crossings do not belong to the MAP.Examples of these include the potential of the casing in a cased crossing; potential ofthe foreign pipe and a Telecom shielded cable. In the next annual report the MAPpotentials only will be presented in the graphs and charts. Apart from these low points,there are genuine low potentials on the line that are due to the condition of the coatingand nature of the local ground.

Each year new ground beds are installed to increase the level of protective currentavailable to the pipe. In this practice old ground beds with increased resistance arealso replaced with new ones. In Year 2001 two new ground beds were installed at KP294.66 and at KP 416. These ground beds will be activated in early 2002.

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 anoperational audit on Epic Energy in the third quarter of 2001. While that audit focusedon gas pipelines, it included a partial review of the Liquids Pipeline. The only issue ofconcern raised in regard to the Liquids Pipeline related to the upkeep of the burn pits,which are no longer used. This will be addressed in 2002 as a specific exemptexpenditure item.

5.2 Environmental AuditsAs the owner of the Moomba to Adelaide Pipeline, Epic Energy is required to have inplace an Environmental Management System. A complete review of that EMS wascarried out in 2001, following the development of SEO's for operating pipelines in SA.The Audit looked at the effectiveness and system structure relating to the SEO's.Modifications were carried out on the Aspects Register and included an update of theObligations Register.PPK Environmental & Infrastructure Pty Ltd were commissioned to undertakeenvironmental monitoring works at several sites along the Moomba to AdelaidePipeline. These sites included Compressor Stations 1 - 7, the Mintaro Meter Station,Peterborough Depot and Torrens Island Meter Station. The objectives of the programare part of ongoing environmental monitoring and walk through inspections to identifysignificant environmental issues.Groundwater monitoring was carried out at selected sites to determine the extent ofhydrocarbon plume beneath the site and whether this has changed since the previous


-17 -

round of monitoring. The 2001 survey provided evidence of natural degradation of theplume. The program is to ensure that any significant breach in the integrity of thescrubber tanks on the above sites is identified, to enable a response strategy to beimplemented if required. Monitoring of previously identified hydrocarbon contaminationwithin the groundwater at the Torrens Island site was carried out to determine themigration of contaminant and assess the potential for natural attenuation. A generalreduction in the hydrocarbon concentration since previous monitoring round hasoccurred with evidence of natural biodegradation of hydrocarbons. Groundwatermonitoring at the Torrens Island Meter Station will continue, to assess the migration ofthe petroleum hydrocarbon contamination within the groundwater and provide evidenceof natural attenuation of the hydrocarbon plume beneath this site.Due to presence of a localised area of phase separated hydrocarbon product in thevicinity of the former soakage pit at Compressor Station 7, a passive skimminggroundwater remediation system was installed in 2001. The objective was to removeas much phase-separated hydrocarbon (PSH) product as practicable from thegroundwater. This reduces the spread of the contamination plume within thegroundwater. The passive skimming unit has been operating effectively and hasreduced the thickness of phase-separated hydrocarbons to a thin film. It has beenrecommended that the unit remain in operation until the rate of PSH recovery becomesnegligible.Existing areas of “African Rue”, an exotic weed along the Right Of Way in the vicinity ofCS5, were monitored and sprayed at appropriate intervals.

5.3 Safety AuditsEpic Energy has developed and implemented a Safety Management System (SMS) forall operations and pipeline systems. An internal audit of the SMS was conducted in2001. Further to this, Det Norske Veritas (DNV) undertook an external review inaccordance with our Western Australia Safety Case requirements.Housekeeping inspections are conducted monthly at all facilities in accordance with ourSMS requirements.

6.0 REPORTS GENERATED IN 2001The following reports were generated and forward to PIRSA during 2001:

• PL1 Annual Report for 2000 submitted to PIRSA 11 April 2001.

• AS 2885 Risk Assessment for the Moomba to Adelaide Pipeline submitted 20December 2001.

7.0 REPORTED INCIDENTSA total of 30 safety and environmental incidents were reported on the Moomba toAdelaide Pipeline, including:

• Unauthorised activity in the Easement:A new fence was erected within one metre of the pipeline on Taylors Road,Anglevale. The landowner drilled a hole 300mm deep within one metre of thepipeline. This work was unauthorised and unsupervised.A new fence was installed on the pipeline easement at Kp 581.2Burra Council removed 400mm of ground cover from the pipeline easement forroad repairs without notifying Epic Energy.


-18 -

Heathgate Resources bogged a grader on the pipeline easement within one metreon the pipeline near Compressor Station 3.

• ErosionWashouts occurred after heavy rains at Muligans Creek on two occasions, eachtime exposing the top of the pipeline for a short distance.Heavy rains caused Moorowie Creek to flow just south of Compressor Station 6and expose the top section of the pipeline.The Balcoracana Creek immediately north of Compressor Station 4 flooded onseveral occasions and twice exposed the top of the pipeline for several metres.

• Relief valves ventingFour relief valves operated in 2001 - Torrens Island Meter Station, Symes RoadMeter Stations, Compressor Station 1 fuel gas skid and Compressor Station 4 fuelgas skid. The largest amount of gas vented was at Compressor Station 1 withapprox 14 TJ of gas vented to atmosphere.

• Pipeline leaksThere was an incident at MLV 24 when the sealant injection nipple dislodged fromthe sealant line, venting gas to atmosphere until repairs were completed. Anestimated 6.9 GJ of gas was vented in this incident.

• Oil SpillsThere was a minor oil spill at Wasleys compressor station when the undergroundoil collection tank allowed a mixture of oil and gas to vent via the breather pipe andcontaminated the ground.The contractor cleaning the meter tubes at Gepps Cross meter station allowedcontaminated water from the cleaning process to spill to ground with the potentialto enter the storm water drains.


-19 -

• Injuries:An employee injured his knee while alighting from the back of a vehicle. Thisrequired surgery and resulted in a roster cycle off work.An employee inadvertently used oxygen instead of nitrogen when testing a reliefvalve. Oil within the valve exploded, resulting in shrapnel injuries to the employee.That employee had several days off work recovering from his injuries.An employee required stitches in his leg after hitting his leg on a protrusion duringroutine maintenance.

8.0 THREATS TO THE PIPELINE

8.1 AS2885 Risk Assessment• The Risk Assessment was commenced in 2001 and was completed in February

2002. This assessment included the Moomba to Adelaide Pipeline, all lateralsand the 500mm Loop Line from Wasleys to Torrens Island.

8.2 Other• Third party activity has is identified as the greatest risk to cause damage to the

Moomba to Adelaide Pipeline. Unauthorised activity on the pipeline easementis the greatest concern.

• The risks identified are from landowners erecting fences or establishing newvineyards and changing the land use, utilities and councils installing newservices and unauthorised use of heavy machinery and earth movingequipment on the easement.

• Natural events such as erosion, flooding of pipeline and impact from floatingobjects, have the potential to cause pipeline and coating damage.

• Epic Energy ensures the pipeline safety through regular and frequent road andaerial patrols, and pipeline warning signs. The risk assessment to be completedin 2002 will give a clearer understanding of any additional risks and supportingactions to rectify potential hazards.

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

Licence Pipeline Licence 1

Licence description Moomba to Adelaide

Location Refer to Figure 1.

Activities covered bythis CEP/SEO.

All regulated activities relating to the operation of the Moombato Adelaide Pipeline.

This SEO does not apply to de-commissioning of the pipeline.A separate SEO 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 ProjectIn each case, the SEO/COP 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 assessed asbeing of LOW environmental significance. Public consultation on the SEO's was notrequired. Under the terms of draft Memoranda of Understanding with DEHAA andPlanning SA, these SEO’s were developed in consultation with both organisations.

-28-

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.

OBJECTIVESOBJECTIVE GOAL(S)

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

1.1 To minimise disturbance to land use anddamage to infrastructure

2. To promote and maintain soil stability 2.1 To ensure there is no erosion on theeasement.

3. To promote and maintain vegetationcover on the ROW.

3.1 To ensure that the easement remainsfree of weeds and pathogens.

3.2 To maintain regrowth of nativevegetation

4. To minimise noise due to operations. 4.1 To ensure operations comply with noisestandards.

5. To minimise the potential for emissionsthat may cause public concern.

5.1 To ensure that uncontrolled emissionsare reported and acted uponimmediately

6. To minimise the risks to public healthand safety.

6.1 To adequately protect public safetyduring normal operation.

6.2 To adequately reduce the likelihood offire.

6.3 To adequately protect public safetyduring 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.


-29-

ASSESSMENT CRITERIAThe 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 (eg 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 (eg 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 (ie goal exceeded, achieved ornot achieved).

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

REPORTING REQUIREMENTSDEFINITIONS

It is a requirement under Section 85 of the Petroleum Act 2000 that any incidents thatare determined to be ‘serious’ or ‘reportable’ incidents must be reported to the Minister.The following descriptions have been provided to help clarify and elaborate on thedefinitions given in Section 85(1) of the Petroleum Act 2000 and Regulation 32(1) ofthe Petroleum Regulations 2000.

Serious IncidentsThe incidents listed below are considered to be to be serious incidents under Section85(1) of the Petroleum Act 2000:

• Loss of containment incident resulting in :

• Serious injury or death,

• Imminent risk to public health or safety, or

• Serious environmental damage or imminent risk of serious environmentaldamage, or

• Interruption or imminent risk of interruption of the natural gas supply.

• Unauthorised activity on the pipeline where the pipeline is actually contacted.


-30-

Reportable IncidentsThe 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 range of KPI’s must be reported in the annual report.

REPORTING REQUIREMENTS

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 Section 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 Section 32 of the Petroleum Regulations 2000.
