Audit Report - Wilpinjong Coal MineIndustry & Investment NSWENVIRONMENTAL AUDITPURPOSEAn Industry & Investment NSW (I&I NSW) Compliance Audit was undertaken atWilpinjong Coal mine operated by Wilpinjong Coal Pty Ltd (a Peabody company)located at Mudgee. The site was audited as part of a joint Department of Planning(D0P), Industry and Investment NSW (I & I NSW) and Department of Environment,Climate Change and Water (DECCW) environmental performance review on themanagement of dust from coal mines to improve environmental performance. Theaudit of Wilpinjong Coal mine was conducted with DECCW auditing against theirEnvironment Protection Licence and I & I NSW auditing the requirements of theMining Lease including the Mining Operational Plan and Annual EnvironmentalManagement Report relating to dust.The audit inspection was undertaken on 9-1 0th September 2010. The procedures andprocesses for conducting the Compliance Audits were consistent with details in theCompliance Audit Handbook, which can be accessed on the DECCW website nsing/cahandbookO6 13 .pdf.This Audit is a controlled document for distribution of the audit agencies and themine owner/operator.This report has been prepared to present the findings of the audit carried out and noresponsibility is accepted for its use in any other context, or for any other purpose.IIOBJECTIVEThe objectives of the audits were:to determine whether the enterprise is complying with Mining Lease andMining Operations Plan Requirements in relation to the audit scope andcriteria;to outline a time frame for follow-up action to address any noncompliances identified during the audit.SCOPEThe area covered by the audit was ML 1573 and covered in the Mining OperationsPlan dated October 2008 to January 2012. The subject area is also covered by theWilpinjong Coal mine Annual Environmental Management Report dated February2010.Prepared by: Scott BrooksControl Copy Document No: 1Date: 910th SeptemberPage 3 of 12
Audit Report - Wilpinjong Coal MineIndustry & Investment NSWThe scope of the audit is limited to the examination of the activitiesundertaken at the Wilpinjong Coal mine in relation to themanagement of dust:Timing, scheduling and sequencing of rehabilitationVegetative cover and quality in completed areasLandform shape in compliance with the MOPTopsoil managementSpontaneous combustion managementGeneral compliance with dust controlling commitments identified in theMOPThe temporal scope adopted for assessment of compliance is generally from thecommencement of the most recently completed AEMR period or a shorter time wherethe auditing item can be adequately assessed.AUDIT CRITERIA, EVIDENCE AND FINDINGSAudit criteria (the requirements against which the auditor compares collected auditevidence) are:Mining Lease Conditions,Most recent Mining Operations Plan and EDG03 MREMP Guidelines Vs3,Annual Environmental Management ReportIndustry accepted best practice standards at Wilpinjong Coal mine, in relationto the management of dust and air quality generally.Audit criteria may include any Management Plan referenced in the MOP.Audit evidence was collected during discussions with site personnel,examination of documentation provided by the mine and/or contained inI&I NSW files, together with observations made during the audit inspection.Assessment of compliance is based on information supplied by the mine,a review of records and documentation relating to the site.Prepared by: Scott BrooksControl Copy Document No: 1Date: 910th SeptemberPage 4 of 12

Audit Report - Wilpinjong Coal MineIndustry & Investment NSWFollowing introductions, the purpose and scope of the Audit was described by theLead Auditor from each of the 2 agencies. The Audit procedure was discussed,including reference to the identification of compliances, non-compliances andobservations as defined below.The lead Auditors confirmed the Audit would be restricted to the areas of the mine tobe audited and the scope was generally associated with activities that can potentiallycreate or lead to dust or a general degradation of air quality.AUDIT PROCEDUREThe relevance and implications of each of the aspects/activities identified in the AuditChecklist were discussed with mining personnel at the opening meeting and again asthe Checklist was filled out. Each of the questions/actions identified on the Checklistwere verified by observation, interview and/or documentation to determinecompliance with statutory approval, agreed MOP operating procedure and industrybest practice. Following the completion of the Checklists a field inspection wascarried out to confirm the findings in the Checklists. Following the field visit anyadditional information required was confirmed and a close out meeting was held toprovide mine management with an outline of the preliminary findings.Compliances, observations and non-compliances were recorded for each of thequestion/audit actions on the Audit Checklist.Appendix 1 summarises the results of the audit with respect to each of the elementsaudited.The following system was used to categorise findings:Prepared by: Scott BrooksControl Copy Document No: 1Date: 910th SeptemberPage 6 of 12
Audit Report - Wilpinjong Coal MineIndustry & Investment NSWDefinition of Audit OutcomesCompliance (C): adequacy of design and appropriateness of implementationwith current Departmental Approvals or Conditions, or compliance withcommitments made by the Company.Observation (0): a finding which is not likely to significantly affect theenvironment but which could lead to process improvement, further research orreference to pest available practice.INon-compliance: an inadequacy in the design and/or implementation againstcurrent Departmental Approvals or Condition. There are 4 subcategories ofnon-compliance;Category 1 (NC red) - a total absence of planning orimplementation of a required operations element which presents animmediate environmental risk or an isolated lapse in control in theimplementation of an operations element which will lead to asignificant environmental risk. A Red non-compliance would have acertain or likely chance of high environmental impact or a certainchance of moderate environmental impact.Category 2 (NC orange) - an isolated lapse or absence of controlin the implementation of an operations element which may not be ofsignificant environment risk. An Orange non-compliance would havea less likely chance of a high level of environmental impact, a likelychance of moderate environmental impact or a certain chance of lowenvironmental impact.Category 3 (NC yellow) - an isolated lapse or absence of controlthat would not have an immediate effect on the environment and in thelong term the effect can be reversed. A Yellow non-compliance wouldhave a less likely chance of a moderate environmental impact or alikely or less likely chance of low environmental impact.Category 4 (NC blue) - a non-compliance related to anadministrative, reporting or monitoring matter.Prepared by: Scott BrooksControl Copy Document No: IDate: 910th SeptemberPage 7 of 12
Audit Report - Wilpinjong Coal MineIndustry & Investment NSWRisk Assessment of Non-compliancesThe significance of any non-compliances identified during the audit process arecategorised. Following risk assessment for non-compliances, an escalating responserelative to the seriousness of the non-compliance is determined to ensure the noncompliance is addressed by the enterprise.The risk assessment of non-compliances involves assessment of the non-complianceagainst two criteria; the likelihood of environmental harm occurring and the level ofenvironmental impact as a result of the non-compliance. After these assessments havebeen made, information is transferred into the risk analysis matrix below.Likelihood of Environmental Harm OccurringCertainCLELikelyLess LikelyHighCode RedCode RedCode OrangeModerateCode RedCode OrangeCode YellowLowCodeOrangeCode YellowCode YellowoWEwThe assessment of the likelihood of environmental harm occurring and the level ofenvironmental impact allows for the risk assessment of the non-compliance via acolour coding system. A red risk assessment for non-compliance denotes that the noncompliance is of considerable environmental significance and therefore must be dealtwith as a matter of priority. An orange risk assessment for non-compliance is still asignificant risk of harm to the environment however can be given a lower priority thana red risk assessment. A yellow risk assessment for non-compliance indicates that thenon-compliance could receive a lower priority but must be addressed.There are also a number of licence conditions that do not have a direct environmentalsignificance, but are still important to the integrity of the regulatory system. Theseconditions relate to administrative, monitoring and reporting requirements. Noncompliance of these conditions is given a blue colour code.The colour code is used as the basis for deciding on the priority of remedial actionrequired by the licensee and the timeframe within which the non-compliance needs tobe addressed. This information is presented in the action program alongside thetarget/action date for the non-compliance to be addressed.While the risk assessment of non-compliances is used to prioritise actions to be taken,I&I NSW considers all non-compliances are important and licensees must ensure thatall non-compliances are addressed as soon as possible.Prepared by: Scott BrooksControl Copy Document No: IDate: 910th SeptemberPage 8 of 12
Audit Report - Wilpinjong Coal MineIndustry & hivestment NSWExplanation of the ChecklistThe purpose of this Audit, from an I&I NSW perspective, is to ensure compliancewith Mining Lease, Mining Operations Plan and AEIVIR requirements. The first stepin this process is to determine what is required within these documents. To do this therequirement needs to first be asked, and then as a second step, determine if therequirement has been implemented on the mine. Where a mine does not have arequirement for a particular activity or aspect, then the answer will be No. This isneither a compliance nor non-compliance.As an example it is asked if the MOP has a requirement for dust suppression on thecoal stockpiles. If this issue is silent in the MOP then the answer is No and theanswer to the next question is N/A as there is no requirement to implement this actionas it is not identified in the MOP. Whether this issue should be covered in the MOPor not is a matter to be considered as a part of the MOP acceptance process and isoutside the scope of the Audit.AUDIT FINDINGSThe I&I NSW Audit Team identified 66 aspects, as part of the Audit Checklist, toaudit at Wilpinjong Coal Mine.The Audit findings were as follows;29 Compliances were identified and documented in the Checklists.6 Non-Compliances were identified and are discussed in more detail below.14 Observations were made arising from auditing of aspect questions. TheseObservations are summarised on the checklists and discussed in more detail below;ICOMPLIANCESICompliances identified of the activity/aspect are either acknowledgement that thedocumentation requested exists, or was found satisfactory from a dust or air qualityperspective.IIIINon-Compliances identified consisted of yellow and blue non-compliances. Therecording of non-compliances and corrective actions taken by the mine are to bepresented in the next Annual Environmental Management Report.N/C Yellow1.Mining Sequence not compliant with the MOPMining in not identified to be occurring south of the suspended Pit 2 workings inthe current MOP period. The inspection found that 2 pits had been recentlyconstructed. One was east of the coal pad and the second was further east ofPrepared by: Scott BrooksControl Copy Document No: 1IDate: 910th SeptemberPage 9 of 12
Industry & Investment NSWAudit Report - Wilpinjong Coal Minethis. Both pits had been mined for coal. The purpose of the Mining OperationsPlan is to identify in both time and space where mining is to occur on the minesite. Opening up extra pits will increase the cumulative affect of the mine on theenvironment and this would not have been taken into account in the assessmentof the MOP. Negotiations to amend the MOP need to be commenced with I&INSW.Behind MOP commitment for rehabilitated areaThe area of completed rehabilitation is behind the area outlined in the MOP.There were 4 N/C's relating to an insufficient area of rehabilitation.Only around 60% of the area identified to be rehabilitated in the MOP in 2009has been completed. Given the area of disturbance equals or exceeds the areaoutlined in the MOP, the larger than planned area of bare ground could lead tothe production of more dust. The rate of rehabilitation needs to be sped up tomatch the MOP.Spontaneous CombustionSpontaneous combustion is occurring in at least 2 locations on the mine. TheMOP refers to a Spontaneous Combustion Management Plan. In this plan itdescribes that inert soil is to be placed over affected areas. An area on the soundbund was affected by spontaneous combustion and was not treated with inertsoil. All spontaneous combustion areas should be managed as required in theManagement Plan.OBSERVATIONSObservations in this Audit are presented in 2 categories:Checklist ObservationsGeneral/field Observations.Checklist Observations.Where an item is considered compliant with an Activity/Aspect on the Checklist, butwarrants comment, an Observation is recorded.GenerallField Observations.Where an Activity/Aspect is observed but will have no effect on the likelihood of dustor poor air quality, a General Observation is recorded. Further if something relevantto the Audit is observed outside the area to be audited, a General Observation isrecorded.Checklist Observations1.Access tracksCondition 20 of the Mining Lease requires access tracks to be constructed toDepartment of Planning requirements. These standards could not be found sotrack standards outlined in the Thiess document "Design and Construction ofPrepared by: Scott BrooksControl Copy Document No: 1Date: 9-1 0th SeptemberPage 10 of 12
IIIIIIIIIIIAudit Report - Wilpinjong Coal MineIndustry & Investment NSWMine Roads was taken as the required standard. This document was verycomprehensive. The tracks were found to be constructed to a satisfactorystandard but they did require maintenance. A number of drains were eithereroded or blocked with sediment.2.Topsoil stockpile recording.There were 2 observations regarding topsoil recording. Both the MOP andAE1\'IR contained a section outlining topsoil storage records. The MOPidentified the topsoil volumes planned to be stripped in the MOP period only. Itdid not show quantities of topsoil carried into the MOP period or topsoil plannedto be used for rehabilitation. The AEMR only showed the quantities of topsoilused. The purpose of both documents is to allow a topsoil budget to be created inthe MOP and the AEMR report against this budget to ensure the use of topsoil ismonitored to prevent a shortfall at the end of mining.Mapped areas of Spontaneous Combustion.As the site contains 2 areas of spontaneous combustion in the overburdenstockpiles, a plan is needed to locate these areas, so their size and location can bemonitored. The only known areas are well monitored and it is acknowledgedthat an infra red site survey is planned to be completed shortly on locating theknown and any unknown areas. This survey needs to be started shortly.General ObservationsGOAThe site was very wet for the duration of the Audit. This prevented anydust from being created and most of the equipment was idle due to wetconditions. This made it very difficult to asses management practices to reducethe risk of dust.The site had a very large area of disturbance relative to the size of themine. More care is needed to ensure the disturbance footprint is kept to aminimum. Once land is disturbed, and not planned to be re disturbed in theforeseeable future, it should be sown with grass to remove the risk of erosionproducing sediment and dust.APPENDICIESAppendix 1Audit Checklist-Appendix 2A plan showing the state of the mine in recent time of the Audit.
