40 8 Risks, incidents and emergencies This section covers the processes used to identify, monitor and manage risks, incidents and emergencies. 8.1 Environmental risk analysis Appendix C analyses the typical inherent environmental risks associated with the asset s operational key environmental performance issues. The environmental risk analysis adopts the methods included in Australian Standard AS ISO 31000: 2009 Risk Management, Principles and Guidelines (Standards Australia, 2009). It includes: Routine operational risks Non-routine operational risks. The analysis then describes the measures that serve to manage these risks and consequently the residual outcome. The OEMP and supporting OEMPSPs serve to introduce risk mitigation controls to reduce: Likelihood, such as training and awareness, as well the assignment of roles and responsibilities Magnitude, such as water quality detention basin maintenance. The risk assessment would be reviewed and updated once every three months. It would also be reviewed ahead of undertaking and non-routine operational maintenance and repair activities Continual improvement Due to the complexity of asset management and maintenance, Appendix C does not include all feasible and reasonable risks. Also, until the asset is operational it is not possible to identify or qualify all risks. As such, the environmental risk analysis process is dynamic and iterative. The environmental risk analysis will be reviewed, and upgraded if required following an incident, emergency, change in legislation, operating and maintenance procedures/activities, audit findings, non-compliance, continual improvement measures or otherwise annually. New, atypical, non-routine or major environmental risks will be included and assessed under environmental risk analysis. They will be included proactively and not reactively to ensure hazards are identified, controlled, and ideally, eliminated before they occur. Where additional key environmental impacts are identified through this process, an appropriately detailed assessment of key environmental impact will be undertaken. The SMC environmental manager will be responsible for maintaining and reviewing the environmental risk analysis process, within input from the. The SMC environmental manager will also be responsible for its update to respond to the above outcomes.

To support this, the will provide SMC with: Monthly noise monitoring results Recorded average daily traffic volumes on the widened M4 Motorway Details of any received operational noise complaints and enquiries. Within 12 months of operation. The water quality plan and monitoring program (WQPMP) prepared for the design and construction of the M4 Widening Major Civil Works was approved by DP&E on 27 April It describes how the requirements of MCoA B7 were met during construction and identifies the frequency for the compliance reporting and independent auditing. SMC will continue the monitoring for at least one year following the completion of construction. If impacts are identified after one year of monitoring, monitoring will continue for a further two years or until the affected waterways and/or groundwater resources are certified by an independent expert as being rehabilitated to an acceptable condition. The monitoring will also confirm the establishment of operational water control measures, such as vegetation swales. The previously approved construction WQPMP has been amended to focus on surface and ground water quality during the asset s operation. SMC will continue to consult with NSW EPA, DPI (Fishing and Aquaculture and Water), WaterNSW, and Sydney Olympic Park Authority, and relevant Councils on the implementation of the WAQPMP. SMC will provide the collected data and interpretative report to DPI Water (if required). Within 12 months of operation: SMC will carry on with the landscaping maintenance procedures and will comply with the landscaping maintenance program detailed in the RMS Specification: M3 Routine Services and all maintenance intervention requirements specified in RMS QA Specification M3 (under M321 Sydney Motorway Corporation M4 Motorway: Operational Environmental Management Plan Page 41 of 59

The following sections provide information regarding the audit scope, methods and responsibilities for conducting the audit and reporting results. The purpose of the operational phase audit process is to review and ensure that all the control mechanisms are overseen and (as needed) corrective actions and lessons learnt are in place. The internal audit will be undertaken by an independent person(s) engaged to audit the asset. The scope of the audit will include the operations, and the effectiveness of this OEMP and its management sub plans. The independent audit(s) are to be undertaken and a copy of the audit be provided to the Secretary and relevant public authorities in accordance with MCoA E Independent environmental audit An independent environmental audit will be undertaken 18 months after the asset is operational. The audit scope will include: agency and council consultation performance compliance with the MCoA and other relevant approvals an accuracy review of the predicted outcomes of the documents listed under MCoA A2 an accuracy review of any approved strategy, plan or program required under the abovementioned approvals recommendation to any corrective actions or improvements The report will be provided to DP&E within 90 days of it being undertaken Non-compliances The independent audit may produce non-conformances with the OEMP or work practices. Environmental non-conformances are defined as: Any potential or actual non-compliance with the MCoA that specifically relate to environmental performance. Any other error, misadventure or incident resulting in actual or potential harm to the health or safety of human beings or to ecosystems that is not trivial, is costly (>$10 000), and/or is harmful to WCX M4 reputation. The SMC asset manager is to be responsible for approving all corrective and remedial actions and the closing out of non-conformance items Corrective actions The independent audit findings, corrective actions and updates will be reported to the Secretary within three months of each audit, or as otherwise agreed by the Secretary. The audit findings report will be submitted to the Secretary and relevant public authorities, together with its response to any recommendations contained in the audit report Other non-compliances and non-conformances Following a review of the incident and compliance tracking register, corrective action is to be identified and determined by the asset manager for an identified non-conformance. This is to reflect the nature and scale of the matter and whether it presents a material risk to human health, the environment or risk damaging property. Corrective actions are to be preventative-based and summarised as follows: Sydney Motorway Corporation M4 Motorway: Operational Environmental Management Plan Page 42 of 59

44 The asset manager notifies the SMC Manager and SMC Operation logistics team. The asset manager is to assign corrective actions and responsibility to a specific member of SMC Operation logistics team including timeframes, follow-up dates and close-out expectations. The action is closed out on the compliance tracking register following observation by the asset manager that the non-conformance and associated risk has been ideally removed, or is being appropriately managed to limit the potential for material harm as far as is reasonably feasible and practical. 9.5 Compliance tracking The CTP prepared to support design and construction was approved by DP&E on 11 May It described how the requirements of MCoA A12 will be met. It also identifies the frequency for the compliance reporting and independent auditing. SMC will use this CTP to during this asset s operation. The CTP contains: Provisions for: Notifying the DP&E before the asset is operational Periodic compliance reviews against the MCoA Periodic reporting to the DP&E including a pre-operation compliance report. All employees, contractors and sub-contractor to be aware and comply with the relevant MCoA relating to their respective roles and responsibilities Reviewing compliance and incident management An independent environmental auditing program Procedures for rectifying any non-compliance identified during environmental auditing. The CTP will operate for at least 18 months. It will independently reviewed and audited as described in section Reporting to DP&E Table 9.3 lists the reporting DP&E reporting requirements under this OEMP.

45 9.7.1 Corrective actions Corrective actions will be identified and determined by the relevant manager and will reflect the nature and scale of the incident and whether it presents a material risk to human health, the environment or property. Corrective actions will be preventative-based. They will be implemented, monitored, checked and reviewed. The corrective action process is summarised as: O&M stakeholders notifying the SMC environmental manager of the non-conformance The SMC environmental manger either preparing an environmental incident report and/or environmental improvement notice The SMC environmental manager assigning corrective actions and responsibility to a specific (or group) of O&M stakeholders including timeframes, follow-up dates, and close-out expectations Closing-out the action following monitoring, and follow-up observation that the non-conformance and associated risks have been ideally removed or are being appropriately managed to limit the potential for material harm as far as is reasonably feasible and reasonable. The SMC environmental manager will review all plans and notices every month for summary reporting so as to provide feedback to senior management. Corrective action statistics will be reviewed annually to set key performance indicators. The actions will also be entered into the compliance tracking program described in section 9.5.

69 1 BACKGROUND 1.1 Purpose To ensure that Roads and Maritime Services has processes to classify and report environmental incidents that may occur during Roads and Maritime managed activities and to comply with its statutory obligations to report certain incidents. 1.2 Scope and Coverage This Procedure is for the use of all Roads and Maritime staff in all regions and divisions where environmental incidents may occur, including where incidents occur during the course of Roads and Maritime s contractors or alliance members undertaking works. The procedure is to clearly define the requirements of Roads and Maritime staff and contractors to report environmental incidents. The procedure does NOT cover environmental incidents caused by traffic accidents or boating accidents nor marine oil and chemical spills covered by the National Plan 1. The Roads and Maritime Environmental Incident Classification and Reporting Procedure relates to incidents involving Roads and Maritime or its contractor/alliance partners and is for internal reporting processes as outlined in this procedure Responsibilities All Roads and Maritime staff and contractors are responsible for reporting an environmental incident in accordance with this procedure when they become aware of the incident. Regional Maintenance Delivery (RMD) shall manage environmental incidents in accordance with the RMD Environmental Incident Fact Sheet at this link. 2 CLASSIFICATION, NOTIFICATION AND REPORTING PROCESS 2.1 Environmental Incident Classification There are three categories of environmental incidents / events that are to be identified and managed as shown in shown in Table 1. Category 1 Incidents -- potentially the most serious incidents. They generally reflect breaches of environmental legislation. Category 2 Incidents - are generally less environmentally serious and generally have lower maximum penalties. Nevertheless, there are sound policy reasons why these incidents need to be identified and reported, including in order to track potential trends that may lead to Category 1 incidents if not addressed Reportable Events - This category captures events that occur outside the scope of reasonable controls and mitigation. 1 The National Plan to Combat Pollution of the Sea by Oil and Other Noxious and Hazardous Substances Version 4.12 February 2016 Printed copies of this document are uncontrolled Page 3 of 17

74 2.4 Regulatory Agency Notification There are specific statutory requirements relating to the notification of pollution or environmental incidents to relevant regulatory agencies. These are summarised in table 3 below Table 3: Environmental Incident Notification Requirements Legislation POEO Act 1997 (see Section 2.5) Regulating Authority EPA and relevant authorities Section Section 148 requirement to immediately notify pollution incidents occurring during an activity that cause or threaten material harm to the environment. Heritage Act 1977 EPA Section 146 requirement to notify the Heritage Council of the location of the relic once a relic has been discovered or located. National Parks and Wildlife Act 1974 Commonwealth Aboriginal and Torres Strait Islanders Heritage Protection Act, 1984 Contaminated Land Management Act 1997 Rural Fires Act 1997 EPA Department of Environment EPA NSW Fire Brigades Section 89A requirement to notify the location of an Aboriginal object that is the property of the Crown. Section 20 requirement to notify the Minister of the discovery of Aboriginal remains. Section 60 requirement to notify if Roads and Maritime activities have contaminated land or if Roads and Maritime owns land that has been contaminated. Section 64 requirement to notify an appropriate fire officer of the inability to extinguish any fire burning during a bush fire danger. Should an environmental incident have the potential to impact on a drinking water supply, the relevant water supply authority must also be advised. It is the responsibility of Environment Managers to liaise with Environment Operations Section prior to notifying regulatory agencies of relevant environmental incidents. 2.5 POEO Act Notification of Material Harm Under Part 5.7 of the POEO Act, there is a duty to notify each relevant authority (identified below) of a pollution incident, where material harm to the environment is caused or threatened. Material harm includes actual or potential harm to the health or safety of human beings or to ecosystems that is not trivial or that results in actual or potential loss (refer definitions in s147 of POEO Act) or property damage of an amount over $10,000.

75 The following notification procedure only relates to pollution incidents. Conservation, heritage and planning breaches described in Section 2.1 are not included in the definition of a pollution incident with respect to Part 5.7 of the POEO Act. Roads and Maritime is not responsible for notifying a pollution incident caused by a traffic or vehicle accident where notification has already occurred. Notification is required by the person carrying on the activity immediately upon becoming aware of the incident. IMPORTANT NOTE The following procedure is to be followed by all Roads and Maritime staff and contractors. Any actual or potential material harm to a person s health or well being or the environment as a result of a pollution incident must be reported immediately to Principal Manager Environment Operations on (02) Contractors who hold an environment protection licence for their activities are responsible for implementing their compliant Pollution Incident Response Management Plan including notifying EPA and the other relevant authorities in accordance Part 5.7 of the POEO Act and any relevant Conditions of their EPL Contractors undertaking works without an EPL are responsible for notifying Roads and Maritime, EPA and the relevant authorities in accordance Part 5.7 of the POEO Act. As soon as a Roads and Maritime employee becomes aware of a Category 1 pollution incident, all Roads and Maritime environment officers and project managers are to immediately notify Principal Manager Environment Operations on (02) of all Category 1 pollution incidents. RMD staff are to notify according to RMD Environmental Incident Fact Sheet. PMEO will assist in making an assessment of the incident and determine whether or not to formally notify the incident to the EPA and other relevant authorities. If for any reason that PMEO is not contactable, staff should contact their regional Roads and Maritime Environment Managers (or Regional Maintenance Delivery Environmental Manager for Regional Maintenance Delivery projects) to assist in assessing whether an incident triggers the notification requirement. If no assistance can be obtained within a reasonable time, you are required to notify the relevant authorities in the order of notification outlined in the table below and provide each agency with the information required in section 2.5 of this procedure. Even if you do not have all the information, you must notify each agency with the information you have at hand and ensure that they are updated as soon as further relevant information becomes available.

76 In circumstances where there is doubt about the need to notify or the relevance of a particular agency, Roads and Maritime should always err on the side of notification. When in doubt, communicate! Relevant Authorities to Notify Table 4 provides the contact details for the authorities that need to be notified in the event of a material harm pollution incident. Table 4: Appropriate Authorities for Part 5.7 Incident Notification Relevant Authority Contact Number Fire and Rescue NSW 000 (for pollution incidents that present an immediate threat to human health or property) (for pollution incidents that do not present an immediate threat to human health or property) EPA environment line The Ministry of Health Via the local Public Health Unit see Appendix 3 WorkCover Authority The appropriate regulatory authority Your Local Council or Western Lands Commissioner for the Western Division (except any part of the Western Division within the area of a local council) Local Council Please call Division of Local Government on to find relevant local council contacts or visit their website on The appropriate contact for the relevant local council and Public Health Unit will vary. All necessary contact numbers should be found in advance and stored for immediate access should a pollution incident need to be notified.

77 Relevant authorities notification order If the incident presents an immediate threat to human health or property, Fire and Rescue NSW, the NSW Police and the NSW Ambulance Service should be contacted first for emergency assistance o call Fire and Rescue NSW on 000 first then o EPA environment line o The Ministry of Health o WorkCover Authority o Local Authority (Council) If there is not an immediate threat to human health or property: o call EPA environment line first then o Local Authority (Council) o The Ministry of Health o WorkCover Authority o Fire and Rescue NSW on All of the above authorities (whether considered relevant or not) must be contacted for each material harm pollution incident to satisfy notification obligations The relevant information to provide Section 150 of the POEO Act provides the information that needs to be notified. It is important to avoid speculation on origin, causes or outcomes of a pollution incident in discussions with the authorities. While it is important not to speculate on the causes of an incident, s150 (1) (d) of the POEO Act requires notification of the circumstances in which the incident occurred (including the cause of the incident, if known) and there is an ongoing duty ensure that relevant information be notified after it becomes known. Section 150 POEO Act - Relevant information to given 1. The relevant information about a pollution incident required under section 148 consists of the following: a. the time, date, nature, duration and location of the incident, b. the location of the place where pollution is occurring or is likely to occur, the nature, the estimated quantity or volume and the concentration of any pollutants involved, if known, c. the circumstances in which the incident occurred (including the cause of the incident, if known), d. the action taken or proposed to be taken to deal with the incident and any resulting pollution or threatened pollution, if known, e. other information prescribed by the regulations. 2. The information required by this section is the information known to the person notifying the incident when the notification is required to be given. If the information required to be included in a notice of a pollution incident by subsection (1) (c), (d) or (e) is not known to that person when the initial notification is made but becomes known afterwards, that information must be notified in accordance with section 148 immediately after it becomes known. Note: if a pollution incident occurs, the above information is to be initially communicated verbally to each relevant authority and is to be followed by written notification within 7 days of the date on which the incident occurred (Clause 101 POEO (Gen) Regs).

78 Complying with these notification requirements does not remove the need to comply with any other obligations for incident notification, for example, those that apply under other environment protection legislation such as an EPL condition or legislation administered by WorkCover. Should Roads and Maritime receive a request from a regulatory authority for a written report regarding an environmental incident, the relevant Project Manager must immediately contact Environment Branch and Legal Branch for advice. Communications with Legal Branch, for the purpose of obtaining legal advice in relation to incidents, may be subject to legal professional privilege. Documents that may be the subject to legal privilege should be clearly identified and sent to Legal Branch prior to producing them to a regulatory agency. Such documents may not be required to be produced to the agencies under written notices to provide information. Environment Branch will provide advice and will co-ordinate a response with Legal Branch. Environment Branch and Legal Branch will assist in the investigation of incidents, prepare legal advice and assist with the preparation of reports to EPA, OEH and DP&I.

90 Definitions Term Ambient Noise Asset Audible Range Background Noise dba: A-weighted decibels MCoA DP&E EMP ENMM EPA EIS Impulsiveness L1 L10 L90 LAeq (period of time) Loudness Noise management levels (NMLs) Definition The all-encompassing noise associated within a given environment at a given time, usually composed of sound from all sources near and far. M4 Motorway: Pitt Street at Parramatta and Homebush Bay Drive at Homebush The limits of frequency which are audible or heard as sound. The normal ear in young adults detects sound having frequencies in the region 20 Hz to 20 khz, although it is possible for some people to detect frequencies outside these limits. Background noise is the term used to describe the underlying level of noise present in the ambient noise, measured in the absence of the noise under investigation, when extraneous noise is removed. It is described as the average of the minimum noise levels measured on a sound level meter and is measured statistically as the A-weighted noise level exceeded for ninety percent of a sample period. This is represented as the L90 noise level The ear is not as effective in hearing low frequency sounds as it is hearing middle frequency sounds. That is, low or very high frequency sounds of the same db level are not heard as loud as middle frequency sounds. The sound level meter approximates the human response of the ear by using an electronic filter which is called the A filter. A sound level measured with this filter switched in is denoted as dba. Minister for Planning Condition of Approval Department of Planning and Environment O&M Contractor s Environmental Management Plan Environmental Noise Management Manual NSW Environment Protection Authority Environmental Impact Statement An impulsive noise is characterised by one or more short sharp peaks in the time domain, such as occurs during hammering. The noise level exceeded for 1 per cent of the time for which the given sound is measured. The sound pressure level that is exceeded for 10 per cent of the time for which the given sound is measured. The sound pressure level that is exceeded for 90 per cent of the time for which the given sound is measured. The LAeq is the A-weighted equivalent continuous sound level, sometimes referred to as the average noise level. It represents a sound level with the same energy content as the actual varying noise level measured. The period of time for which the Leq is calculated over is defined by the type of noise being measured, the time of day and the regulatory requirements. A 3dB increase represents a doubling of the sound pressure, however an increase of about 10dB is required before the sound will subjectively appear to be twice as loud. That is, a sound of 85dB is twice as loud as a sound of 75dB which is twice as loud as a sound of 65dB and so on. That is, the sound of 85dB is four times as loud as a sound of 65dB. Typically smallest change which can be readily heard by the average person is approximately 3dB. An increase beyond 5dB is considered to represent the level at which a change in loudness begins to be clearly perceived. The noise management levels are described in the Interim Construction Noise Guidelines (ICNG, 2009). They are typically used to assess the impacts of construction and maintenance noise, however they can be to inform the management of general operational noise. Noise management levels are calculated by using the rating background level. Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 1 of 30

Sound Level Meters can be rated to perform to a specific standard, defined by International Standards. Ten times the logarithm to the base 10 of the ratio of the sound power of the source to the reference sound power. It represents the inherent acoustic energy of a noise source and therefore does not change with distance or environment. Ten times the logarithm to the base 10 of the ratio of the sound pressure of the source to the reference sound pressure. It is the most common way of measuring the magnitude of sound at a distance from a noise source. Tonal noise contains one or more prominent tones (i.e. distinct frequency components), and is normally regarded as more offensive than broad band" noise.

93 1 Introduction 1.1 Purpose and application This document comprises the Noise and Vibration Management Sub-plan (OEMPSP1). It applies to all activities with the potential to: Generate noise that may affect adjacent sensitive receivers Generate vibration that may cause cosmetic or structural building damage or result in amenity impacts Result in a change in operational road traffic noise. OEMPSP1 also considers the: Maintenance and the ongoing effectiveness of noise mitigation infrastructure (e.g. noise walls) Equipment maintenance to ensure its noise and vibration performance is in line with manufacturer specifications and tolerances. The OEMPSP1 forms part of the asset Operational Environmental Management Plan (OEMP). 1.2 Objectives The plan s objectives are: Manage all activities to ensure they do not harm or impact on noise and vibration sensitive receivers or affect building integrity Ensure activity-based noise and vibration does not exceed guidance limits Work under a target of not receiving any noise or vibration complaints Ensure all noise and vibration mitigation infrastructure is maintained and effective. 1.3 Content The plan provides for the following provisions: Noise control during maintenance and repair work Vibration control during maintenance and repair work Equipment maintenance Maintenance of noise mitigation infrastructure Management of operational road traffic noise Operational noise compliance and assessment.

94 2 Monitoring and auditing the plan OEMPSP1 will be assessed and reviewed in accordance with section 1.3 and section 10.1 of the OEMP. Specifically, it will be reviewed: In preparing for a change in: Legislation or regulation Licencing or approval conditions Operations or staff. Following: Routine inspections, monitoring and audits where there is an associated observation, corrective action, and/or environmental improvement notice issued (refer to section 9.7 of the OEMP) An incident or emergency (refer to section 8.2 of the OEMP) A recorded noise/vibration exceedance Persistent noise/vibration complaints Continuous non-conformance. Otherwise the plan will be audited, reviewed and modified annually. Periodic site inspections, as described in Chapter 9 of the OEMP, will also be used to review environmental performance. Where there is inconsistency between the plan s intention and the inspection/audit findings, the management procedures and protocol will be reviewed and amended as necessary to ensure continuous improvement. Reviews will comprise: documentation Observing procedure and protocol onsite Issuing corrective actions or environmental improvement notices Re-auditing performance once the corrective actions/improvement notices have been implemented.

98 4 Existing environment 4.1 Noise sensitive receivers The following noise-sensitive receivers are close to the asset footprint. Table 4.1: Sensitive receiver types Sensitive receiver type Considered sensitive to construction noise (i.e. maintenance and repair work) Commercial premises Industrial facilities Other (such as cinemas, theatres). Considered sensitive to construction and operational noise (i.e. maintenance, repair and road traffic noise): Residents Educational institutions Child-care centres Hospitals and other medical facilities Places of worship Recreational areas Given the high number of sensitive receivers adjacent to the asset footprint they were grouped into noise catchment areas (NCAs) in the approved project EIS. Each NCA contained a representative number of similar receivers (i.e. commercial properties or residential properties). Rather than assessing the potential impact at each receiver, the impact was assessed at the closest receiver in the NCA. As shown in Figure 4.1, 19 NCAs were developed in the EIS. Table 4.2 summarises their characteristics.

100 Figure 4.1 Noise sensitive receivers 4.2 Vibration sensitive receivers The guidelines referred to in Table 3.4 describe recommended safe working distances to avoid vibration impacts from typical construction plant. They are: 75 metres to prevent cosmetic building damage (excluding heritage-listed structures) 100 metres to prevent amenity-related (human comfort) impacts. As such, the majority of the NCAs and receivers described above are also considered vibration sensitive in terms of any site work as per Assessing Vibration: A Technical Guideline (NSW DEC, 2006) and the CNVG (Roads and Maritime, 2016). 4.3 Noise mitigation infrastructure Section of the approved project EIS predicted that in upgrading the M4 Motorway about 740 residential properties and 50 non-residential receivers would be eligible for noise treatment by The approved project EIS also described the mitigation controls that needed installing within and adjacent to the asset footprint to reduce noise levels at the receivers described in the previous section. Specifically, the RNP (NSW DECCW, 2011) and NMG (Roads and Maritime, 2015) define four types of mitigation that can be applied to reduce operational noise impacts as being: Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 11 of 30

101 Road design and traffic management Low noise pavement surfaces In-corridor noise barriers and mounds At-property treatments or local barriers and mounds. Under the approved project, the following noise treatment measures were included: Low noise pavement surfaces within the extent of the asset footprint A composition of new and upgraded noise barriers in the locations shown on Figure 4.2 At-property treatments. The barriers locations on Figure 4.2 show where: Existing barriers have been retained Existing barriers have been supplemented New barriers were built. The noise barriers were built to heights of up to six metres. This provided sufficient noise reduction to comply with the RNP (NSW DECCW, 2011). There were 325 receivers that were classified as eligible for acoustic treatment work, including one school and one day care centre. The rest were residential housing (units and houses). Figure 4.2 shows the property treatment maps presented in Appendix I of Appendix E of the approved project EIS and the barrier locations.

103 Figure 4.2 Noise treatment maps and barrier locations 4.4 Changes introduced under the operational noise compliance review Operational noise review The controls described in section 4.3 were identified mitigate for the above predicted impacts. However, the assessment was clear in identifying the inherent limitations and inaccuracies in noise modelling. For that reason, Roads and Maritime committed to undertake an operational noise review (mitigation measure NV-4, refer to Table 3.1 above and section 9.3 of the OEMP) within 12 months of the upgraded road operating. The review will: Monitor noise in a number of agreed locations to confirm the baseline Compare actual noise performance against predicted noise performance (i.e. assess compliance with the operational noise levels) Assess the performance and effectiveness of the noise treatment measures and confirm if they need adjusting or supplementing Identify the need for any additional feasible and reasonable noise mitigation measures consistent with the NMG (Roads and Maritime, 2015). This monitoring and reporting will be completed by the end of Q providing the asset is operational by Q Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 14 of 30

104 4.4.2 Unexpected findings If the operational noise review verifies the noise to be less than predicted, SMC will consult NSW EPA and the DP&E to identify and agree if any mitigation controls or management measures can be relaxed over time. Conversely, if the operational noise review results verify there to be more receivers subject to noise levels that are higher than predicted then SMC will undertake additional monitoring and: The noise monitoring data will be reviewed The prediction methods will be reviewed The existing controls will be reviewed and revised Corrective action will be implemented. As the asset continues to operate the surrounding environment and land uses will change. As such new receivers may be introduced. However, there will be no legal responsibility on SMC to provide noise treatment for future development or land use changes. However, there will be an obligation on all O&M stakeholders to manage and control noise and vibration when undertaking site work, as allowed for in Chapter 5.

The observations of the person undertaking the measurements will be reported including audibility of construction noise, other noise in the environment and any discernible construction activities contributing to the noise at the receiver. Stationary test procedures according to AS Acoustics: Measurement of airborne noise emitted by earth-moving machinery and agricultural tractors Stationary test condition. The testing method includes: Sound level meter configured for Fast time weighting and A frequency weighting. The test environment will be free from reflecting object Tests will not be carried out during rain or when wind speed exceeds 5 m/s In accordance with AS , a minimum of three measurement points will be defined at locations on the hemispherical surface around the plant with the radius determined by the basic length of the machine The A-weighted Leq background noise at the measurement locations will be at least 6 db and preferably 10 db below the level with the plant operating Both Leq and L10 levels will be measured and reported. Attended vibration monitoring will be undertaken when checking the safe working distances from construction plant (e.g. compaction plant) or in response to a complaint. The testing method includes: Monitoring to be conducted for at least three distances from the plant, including a representative distance for the nearest sensitive structures and/or receivers The testing will be conducted at each location to obtain a suitable representation of the range of vibration levels that would occur from the tested plant The plant will be tested in the settings in which it is expected to operate. For vibratory rollers this may include both High and Low settings Peak partial velocity (PPV) vibration levels and the dominant frequency of the vibration will be recorded for assessment against the structural and cosmetic damage criteria. In situations in which human comfort is also of concern then the root mean square vibration level should also be recorded. Continuous vibration monitoring will be undertaken where vibration from a construction activity may exceed cosmetic damage criteria at a sensitive structure, where activities may occur within safe working distances for cosmetic damage. The testing method includes: Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 17 of 30

108 6 Noise and vibration control measures 6.1 Overview The O&M Contractor will implement controls to ensure: Noise and vibration is managed for all planned activities All noise and vibration generating equipment is on an active maintenance schedule All noise mitigation infrastructure is on an active maintenance schedule Operational road traffic noise is managed Noise and vibration is managed during an incident and emergency. SMC will have overall responsibility for maintaining the asset to ensure it remains effective in managing operational noise and vibration. As such, the above will be supplemented by: Ensuring the asset and its associated equipment and infrastructure operates to its environmental performance specifications to control and abate noise and vibration Allowing for noise and vibration monitoring in instances where there is a substantiated complaint or there is evidence of any equipment and/or infrastructure fault or failure Allowing for revision in the mitigation controls following persistent issues and complaints Determining the need to maintain, replace or upgrade the noise mitigation infrastructure/controls if they are found to be unsatisfactory. The requirement to maintain, replace or upgrade any road or noise mitigation infrastructure may need approval either under Part 5 of the NSW Environmental Planning and Assessment Act 1979 or as a modification approval under Part 5.1 of the same Act. The must consult the SMC environmental manager to discuss the proposal to maintain, retain or upgrade any of this equipment and confirm what approvals will be required before its implementation. 6.2 Operation and maintenance activities Each O&M stakeholder is to annually prepare and update a schedule of activities that require the use of noise and vibration-generating equipment revising and/or supplementing the information in Table 6.1. For reference the O&M stakeholders comprise: Sydney Motorway Corporation (SMC): asset delivery and operation : asset maintenance and repair.

110 6.3.3 Controls Table 6.2 lists the management control steps that will be implemented to plan, manage, monitor and review environmental performance. Table 6.2: Environmental controls Step Requirement Responsibility Control 1: Noise generated during planned site work Notes: the following procedure would be used for all routine planned site work. This includes activities that are undertaken frequently (e.g. more than once per quarter, such as vegetation management) and activities that are undertaken infrequently (e.g. once every five years, such as pavement and water quality basin renewal). The s EMP will be used to manage noise during planned routine activities. The EMP will be reviewed and updated annually. Regardless of the above differences, the same steps will be followed. 1.1 Map noise sensitive receivers relative to the work locations. O&M stakeholders Note: the location and type of receivers may have changed due to development in the area. Therefore, there is the requirement to confirm the location and validity of all noise sensitive receivers. 1.2 Obtain baseline noise monitoring data where there are none available, or the data needs updating in light of changes in the local noise environment since 2013 (the date of the last monitoring). 1.3 Establish ambient conditions and associated noise management levels for each catchment area/receiver as per the CNVG (Roads and Maritime, 2016) 1.4 Prepare a schedule of all noise-generating activities associated with the planned routine site work (i.e. clearing, cutting, grinding). Determine the duration and location where the noise-generating activities are planned to take place. 1.5 Predict the noise levels that are expected during the planned routine site work and identify any activities/locations where there are expected to be noise management level exceedances and the potential to cause sleep disturbance if out of hours work is planned. 1.6 Either update the s EMP as part of the annual review, otherwise prepare an activity specific SOP to describe the relevant controls that will be implemented to manage predicted noise exceedance for the planned routine site work. O&M stakeholders O&M stakeholders SMC operations and safety manager O&M stakeholders Note: The level of assessment required by the CNVG (Roads and Maritime, 2016) varies according to the number of receivers affected and the duration of the works. 1.7 Undertake additional monitoring in locations where routine work requires the prolonged removal of noise walls and barriers to determine the impact on adjacent receivers; as per the CNVG (Roads and Maritime, 2016), and the RNP (NSW DECCW, 2011) for road traffic noise. Introduce additional controls such as restricted working hours and/or the use of temporary shields or walls where the assessment predicts likely impacts on the above receivers. 1.8 Include noise management measures in the s EMP or activity specific SOP as required. These measures need to respond to the work schedule and the requirements for out of hours work. Generally, the provisions of the procedure to avoid vibration impacts will involve some of all of the following controls: Provide onsite training through inductions and toolbox talks as per Chapter 6 of the OEMP. Position the work (or equipment) away from noise-sensitive receivers. Maintain entry and exit points to any work sites away from noise sensitive receivers. O&M stakeholders SMC/ Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 21 of 30

111 Step Requirement Responsibility Include additional temporary noise barriers and protection for the duration of the work. Substitute or revise the equipment schedule to favour using lower noisegenerating alternatives. Prevent equipment from idling and warming up. Minimise working in the same location or using the same plant on consecutive days/nights. Where feasible, undertake high noise-generating activities during the day. Limit or restrict the use of certain equipment at night. Prevent the use of reversing alarms at night unless there is a mandatory safety requirement. Ensure all equipment is fitted with suppression equipment, maintained in an efficient condition, and operated in an efficient manner. Include additional control devices where there are predicted noise exceedances despite the use of suppression equipment. Include additional measures where the work will involve the removal of noise barriers, walls or other treatment measures that would impact on adjacent receivers as per Control 1.7. Prevent loading and unloading away from sensitive receivers. Limit the use of noisy equipment operating simultaneously. Prevent the use of compression braking. When using tonal or impulsive equipment, allow three hours of operation followed by at least one hours respite. 1.9 Allow for ongoing noise monitoring during the work to ensure the activities achieve the predicted noise levels Revise the safeguards and management measures if the noise monitoring undertaken during the activity shows there to be an exceedance of the noise management levels Ensure that any out of hours work complies with G36: Environmental Protection (Version 3.0, Roads and Maritime, 2016), the CNVG (Roads and Maritime, 2016), or the relevant standards at the time. SMC environmental manager SMC environmental manager SMC environmental manager Control 2: Vibration generated during planned routine site work Notes: the following procedure would be used for all routine planned site work. This includes activities that are undertaken frequently (e.g. more than once per quarter, such as vegetation management) and activities that are undertaken infrequently (e.g. once every five years, pavement and water quality basin renewal). The O&M Contractor s EMP will be used to manage planned routine activities. The EMP will be reviewed and updated annually. Regardless of the above differences, the same steps will be followed. 2.1 Map vibration sensitive receivers relative to the work locations. O&M stakeholders Note: the location and type of receivers may have changed due to development in the area. Therefore, there is the requirement to confirm the location and validity of all noise sensitive receivers. 2.2 Prepare a schedule of all vibration-generating activities associated with the planned routine maintenance and repair work (i.e. jackhammering, piling, vibratory rolling). Determine the duration and location where the vibration-generating activities are planned to take place. 2.3 Establish safe working distances as described in the CNVG (Roads and Maritime, 2016) and the vibration limits within Assessing Vibration: A Technical Guidelines, BS 7385 and DIN Confirm if any planned routine work would take place closer than the safe working limits or would exceed vibration limits for heritage items stated in the above guidance.

112 Step Requirement Responsibility 2.4 Either update the s EMP as part of the annual review, otherwise prepare an activity specific SOP to describe the relevant controls that will be implemented to manage predicted noise exceedance for the planned routine site work. 2.5 Include vibration management measures in the s EMP or activity specific SOP as required. These measures need to respond to the work schedule and the requirements for out of hours work. Generally, the provisions of the procedure to avoid vibration impacts will involve some of all of the following controls: In the first instance, review the equipment schedule. Identify equipment alternatives (where possible) to remove the risk of cosmetic damage, human amenity impacts or the potential to cause sleep disturbance if the work is planned to take place at night. This will be achieved by selecting smaller equipment that generates less vibration. If the impact cannot be avoided, undertake a location-specific vibration assessment before starting work. Confirm locations where there is a regarded potential for vibration impacts. Consider building condition surveys for receivers that are located within the safe working distances before starting work. Consider the requirement for vibration monitoring during the work activity. Limit or restrict the use of certain equipment at night. Allow respite periods when using tonal or impulsive equipment. 2.6 Allow for ongoing vibration monitoring during the work to ensure the activities achieve the safe working distances. SMC environmental manager Note: Building condition surveys maybe needed before and after vibration intensive work to determine any damage or in response to community concerns. 2.7 Revise the safeguards and management measures if the vibration monitoring undertaken during the activity shows there to be an exceedance of the limits. Review the impacts caused by the exceedance should be undertaken to determine if damage has occurred to sensitive receivers. 2.8 Ensure that any out of hours work complies with the quality assurance requirements specified in the Roads and Maritime specification G36: Environmental Protection (Roads and Maritime, 2016) and the CNVG (Roads and Maritime, 2016), or the relevant standards at the time. SMC environmental manager SMC environmental manager Control 3: Routine equipment maintenance Notes: this control will apply to all noise-generating equipment onsite. This includes mobile equipment, plant and machinery that will be used to undertake routine site work, which is the responsibility of the O&M Contractor. The noise monitoring results will be compared against the performance rating limits (sound power levels), and previous monitoring data, to ensure the equipment is functioning properly and within manufacturer specifications. The monitoring will take place during a typical operating cycle. 3.1 Prepare a schedule of all noise generating plant and equipment associated with the asset and determine the sound power levels of each item. Update the schedule annually or following a change in operations, equipment, or legislation. 3.2 Fixed equipment: either annually, following a complaint, or a change in operations, monitor the noise generated at the nearest sensitive receiver, the complainant s property or a representative location to ensure that the sound pressure levels meet the criteria of the INP (NSW EPA, 2000). 3.3 Mobile equipment: either once per quarter, following a complaint, or change in maintenance or repair activities, monitor the noise generated within specified set distances from the equipment or otherwise at the complainant s property or a representative noise sensitive location to ensure that the corresponding sound pressure level meets the criteria of the INP (NSW EPA, 2000). SMC asset manager SMC asset manager Sydney Motorway Corporation M4 Widening Motorway: OEMPSP1: noise and vibration management sub-plan Page 23 of 30

113 Step Requirement Responsibility Non-compliance 3.4 Where the monitoring shows non-compliance with the INP (NSW EPA, 2000) criteria, prepare a letter, report or describing the current noise emissions compared with the initially measured sound power levels obtained under Control 3.1 and the reason for the non-compliance. The letter/report/ will also detail the conditions when the monitoring was undertaken, including operating configuration and meteorological conditions and confirm the reason(s) for any departure between the monitoring results, the sound power levels determined in Control 3.1 and the resultant sound pressure levels measured at the compliance point, allowing for natural fluctuations and expected real world variations. Identify any non-conformances or failures to meet the fixed plant specification limits. 3.5 Prepare an equipment noise SOP describing what is required to improve the noise performance of the equipment ranging from (a) maintenance, (b) equipment replacement, and/or (c) the introduction of additional noise controls. SMC asset manager SMC asset manager 3.6 In preparing the procedure, review the OEMP and this sub-plan. SMC environmental manager and SMC asset manager 3.7 Submit the procedure outlining the relevant issues. Given that the procedure is a summary of the requirements, and the urgency of the situation, it should take no longer than two working days to prepare and submit. SMC Asset Manager Regulatory notification 3.8 Review the procedure to ensure all requirements can be reasonably implemented. Additional advice will be sought if required. SMC asset manager 3.9 Review the procedure to confirm if regulatory notification is required. SMC general manager 3.10 If regulatory notification is required, complete a standard notification letter.

114 Step Requirement Responsibility 3.17 If the monitoring shows the procedure to be effective seek clarification in writing that its provisions are effective and should be adopted under the OEMP and this management sub-plan If the monitoring shows the procedure to be ineffective, the above steps must be followed again from Control 3.4b and the provisions of the procedure must be revised or supplemented Maintain monitoring after the provisions of the procedure are implemented to determine compliance with the INP (NSW EPA, 2000) criteria. If there is any change in the monitoring levels, consider revising or relaxing the management plan controls. Conversely, if the noise management levels are not met at any time then the above steps must be followed again from Control 3.4b. SMC environmental manager SMC environmental manager SMC environmental manager Control 4: Routine noise mitigation infrastructure maintenance Notes: this control will apply to the noise walls, barriers and mounds. While the asset includes low-noise surface pavement its maintenance will form part of the asset s overall maintenance schedule and the requirement for regrading, resurfacing and/or patching the road. The requirement to maintain, replace or upgrade any road or noise mitigation infrastructure may need development consent or approval. The relevant O&M stakeholders must consult the SMC environmental manager to discuss the proposal to maintain, retain or upgrade any of this equipment and confirm what approvals will be required before they are introduced. 4.1 List all noise management infrastructure on a maintenance schedule. Update the schedule annually or following a change in operations, equipment or legislation. 4.2 Either annually, following a complaint or infrastructure failure, monitor the noise at representative receivers that are/were treated by the noise infrastructure to determine compliance. 4.3a If the monitoring shows compliance, prepare a letter or memo confirming this. SMC asset manager Non-compliance 4.3b Where the monitoring shows non-compliance, prepare a letter, report or describing the current noise exceedances and the reason for the non-compliance. The letter/report/ will also detail the conditions when the monitoring was undertaken and confirm the reason(s) for any departure, allowing for natural fluctuations and expected real world variations. 4.4 Prepare a noise mitigation infrastructure repair SOP describing what is required to improve the noise performance of the infrastructure ranging from (a) maintenance/repair, (b) replacement, and/or (c) the introduction of additional infrastructure controls.

SMC environmental manager 4.11 Implement the procedure. SMC operations and safety manager 4.12 Undertake noise monitoring during typical operational conditions at representative locations to monitor the effectiveness of infrastructure repairs/additional controls If the monitoring shows the procedure to be effective seek clarification in writing that the management plan provisions are effective If the monitoring shows the procedure to be ineffective, this procedure must begin at Control 4.3b, and the management controls revised or supplemented Maintain monitoring after the provisions of the procedure are implemented to ensure they remain effective. If there is any change in the monitoring levels, consider additional (a) maintenance, (b) replacement, or (c) additional infrastructure controls. Conversely, if the noise criteria are not met at any time, then this procedure should be repeated from Control 4.3b. SMC environmental manager SMC environmental manager SMC environmental manager SMC environmental manager and O&M contractor Control 5: Operational noise compliance Notes: there will be a requirement to undertake noise monitoring within 12 months of operation in accordance with CoA E5 (refer to Table 3.1) 5.1 Within 12 months of operation (unless requested by DP&E) undertake operational noise monitoring at agreed locations. This will be supplemented with count data on the M4 Motorway and Parramatta Road to validate the noise levels. 5.2 Prepare an operational noise compliance report to document the noise monitoring. The report will at least include: The context, conditions, locations and frequency where the monitoring was undertaken and the likely reason(s) for any departure from the predicted values A statement of compliance or consistency with the predicted operational noise levels as described in Appendix E of the approved project EIS A discussion if and where the WestConnex strategic traffic model needs revising or recalibrating to account for variations in regional and local growth from the inputs to the existing model Where there is a non-compliance, review the effectiveness and performance of the introduced noise mitigation measures and infrastructure in accordance with operational noise review undertaken to be consistent with MCoA E2 (refer to Table 3.1), and the controls and assessment included in the EIS and submissions report consistent with MCoA A2 Complaints and enquiries received from the date of operation to the date the report is finalised, including the nature of the complaint, the action taken and any residual outcome (refer to section of the OEMP) Proposed additional feasible and reasonable measures to supplement the mitigation controls and infrastructure where the operational noise monitoring is inconsistent/shows an unexpected exceedance. This will include where the measures will be implemented, and how their effectiveness will be measured The report will be issued to DP&E and the NSW EPA 60 days of undertaking the monitoring. 5.3 Contact Roads and Maritime (Environment Branch) and discuss the need to revise or update the WestConnex strategic traffic model and noise model to respond to revised or higher-than-expected growth in the area than modelled originally.

116 Step Requirement Responsibility 5.4 Review the need for supplementary or additional noise mitigation controls consistent with the NMG (Roads and Maritime, 2015) in the event that the noise monitoring confirms an exceedance of the predicted modelling prepared for the EIS and/or during the detailed design (refer to MCoA E5). Prepare (if needed) and submit a supplementary noise mitigation strategy to NSW EPA and NSW DP&E. SMC environmental manager 5.5 Implement the confirmed and agreed supplementary noise mitigation strategy. SMC environmental manager 5.6 Undertake noise monitoring during typical operational conditions at representative locations to monitor the effectiveness of any additional noise mitigation. 5.7 If the monitoring shows the controls to be effective, seek clarification in writing from an acoustician (and the regulator if required). 5.8 If the monitoring shows the plan to be ineffective, this procedure must begin at Control 5.4 to revise and/or supplement the management controls. 5.9 Maintain monitoring after the provisions of the supplementary noise mitigation strategy are implemented to ensure it remains effect. If there is any change in the monitoring levels, consider additional controls. Conversely, if the noise management levels are not met at any time then this procedure should be repeated from Control 5.4. SMC environmental manager SMC environmental manager SMC environmental manager Control 6: Non-routine (incident/emergency) work Notes: this control will be followed as part of the incident and emergency response process described in Chapter 8 of the OEMP. The following control steps will only be introduced where it is safe to do so. They will also only be introduced where there is time to respond to the incident or emergency. In an event where the response is immediate to avoid any risk to human life, property and the environment, then it may not be feasible or reasonable to undertake the following control steps. Control 6 will be supported by Control 3 to ensure that the equipment used during an incident or emergency is well-maintained within manufacturer specifications. Training and prevention 6.1 Undertaken incident management training as part of the compliance, training and awareness measures described in Chapter 6 of the OEMP. This will include measures to: Identify potential incidents and emergencies that would involve the use of noisegenerating equipment Assess the likelihood of the incident or emergency occurring to determine the potential need to use noise and vibration generating equipment Eliminate any risk for noise and vibration complaints during an incident and emergency by maintaining fixed and mobile equipment as per Control 3 Train staff in the correct use of noise and vibration generating equipment in an incident and emergency situation. Management 6.2 Where it is safe to do so, set up mobile acoustic screens or equipment shields around equipment used in an incident and emergency. 6.3 Where there is time, and noise and vibration generating equipment is used for more than 24-hours, update the mobile road signage and website to notify the community of the expected higher levels of noise and vibration and the length of time it is likely to last. 6.4 Brief the person/people manning the 24-hour telephone number and address of the incident and emergency so that they can respond to any complaints quickly. Consider using automated messaging or providing a mail shot to the community to communicate the incident and emergency where the use of noise-generating response equipment is expected to last longer than 72-hours.

126 3.1.2 Legislation The following legislation is relevant to OEMPSP2. Table 3.2: Legal obligations Legislation Relevance Traffic and transport Roads Act 1993 Traffic management and working on public roads NSW Road Regulation 2008 Measures to protect traffic and provide public safety Permits, licences and approvals The asset does not routinely operate under any additional permits, licences and/or approvals. However, any O&M stakeholder would need to obtain a Road Occupancy Licence from the Transport Management Centre or relevant Council under section 138 of the NSW Roads Act 1993 if it intends to do the following planned work onsite: Erect a structure or carry out a work in, on or over a public road Dig up or disturb the surface of a public road Remove or interfere with a structure, work or tree on a public road Pump water into a public road from any land adjoining the road Connect a road (whether public or private) to a classified road. Such a licence is not needed if responding to an incident or emergency. Also, licences are typically not granted: Between 6am and 10am and 3pm and 7pm on weekdays During special events At times of other known peak traffic demand. The O&M stakeholders will obtain approval from Roads and Maritime and the relevant Authority before occupying, modifying or affecting any roads, footpaths or cycleway which are open to the public. 3.2 Other obligations Environmental policies, guidelines and principles Roads and Maritime and other Government agencies have developed guidance and policy for managing noise and vibration. The O&M stakeholders will work under this guidance and policy: Table 3.3: Environmental policies, guidelines and principles Legislation Relevance General operations and maintenance Guide to Traffic Management (Austroads, 2014) Guide to Traffic Generating Developments (Roads and Traffic Authority, 2002, as amended) Traffic Control at Work Sites (Version 4, 2010, Roads and Maritime) Traffic management and working on public roads Sydney Motorway Corporation M4 Widening Motorway: OEMPSP2: traffic and transport management sub-plan Page 6 of 13

127 4 Existing environment Appendix D of the approved project EIS describes the traffic and transport conditions before the asset was upgraded and predicts how these would change following its upgrade. 4.1 General characteristics The M4 Motorway is about 40 kilometres long connecting the Blue Mountains in the west with Parramatta Road in the east. The main roads adjacent to the M4 Motorway include: The Great Western Highway Parramatta Road. The main roads that cross the M4 Motorway are: Silverwater Road Hill Road Homebush Bay Drive/Centenary Drive. Additional roads as a result of the upgrade include: James Ruse Drive 4.2 Freight and commercial vehicles The M4 Motorway remains important and essential for freight (heavy) and commercial (light) vehicles. About 37 per cent of all traffic travelling along the M4 Motorway are freight vehicles and the average number of weekday freight trips is expected to increase by 40 per cent between 2011 and 2031 The M4 Motorway carries more than double the proportion of work-related business trips compared to other parts of Sydney s road network. 4.3 Commuters, public transport and active transport The number of people commuting to and from work along the M4 Motorway during the peak periods is excessive, which has caused congestion and was one of the major factors contributing to the upgrade of the M4 Motorway. The Motorway also supports over 50 daytime bus routes. Cyclists are permitted to use the M4 Motorway and are also provided with a separated cycleway around the Homebush Bay Drive interchange and a shared use paths around Parramatta. While people are not permitted to walk along the M4 Motorway, there are footpaths along the roads that run adjacent and over/under the motorway. There are also a number of specific pedestrian-only crossings over the M4 Motorway. 4.4 Network conditions In 2012, collected survey data confirmed that it took about 15 minutes to travel between Church Street and Homebush Bay Drive in the morning peak period, however this could increase to 25 minutes during heavily congested periods. In the afternoon peak period this journey westbound would take about 23 minutes typically. This compares to the journey taking about eight minutes in either direction in the inter-peak (middle of the day). Also as of 2012, it was considered that the queuing and congestion on the M4 Motorway was significant, this being another driver for upgrading the road as part of the WestConnex scheme. Now that the M4 Motorway is upgraded and operational it is predicted that motorists would typically save up to nine minutes on their journey times between Church Street and Homebush Bay Drive. This is set to increase to 14 minutes eastbound and 10 minutes westbound once the whole WestConnex scheme becomes operational in The other expected change is a traffic reduction on the M4 Motorway as people avoid incurring the tolls. It predicts that there would be: About 3,350 vehicles per hour using the M4 Motorway in the morning peak period increasing to about 3,630 vehicles per hour once the whole WestConnex scheme is operational About 3,510 vehicles per hour using the M4 Motorway in the afternoon peak period increasing to about 3,820 vehicles per hour once the whole WestConnex scheme is operational.

129 5.3 Management controls This section sets out the controls (and monitoring) that will be implemented to manage traffic, transport and access impacts form the above activities. These controls satisfy MCoA E8 Fii. Table 5.2 lists the management control steps that will be implemented to plan, manage, monitor and review environmental performance. Table 5.1: Environmental controls Step Requirement Responsibility Control 1: Traffic monitoring The is responsible for continuously monitoring traffic conditions on the M4 Motorway. The inclusion of intelligent transport systems allows for the partial adjustment of traffic conditions on the motorway such as variable speed limits, ramp metering controls and use of the hard shoulder; all measures that help promote and maintain the operational traffic performance. Control 2: Traffic management during routine O&M activities O&M vehicles 2.1 Ensure that all O&M vehicles enter and leave any work areas and the maintenance depot (at Adderley Street, Auburn, immediately adjacent to Newton Street South) via designated routes that are restricted to main arterial roads including: M4 Motorway Church Street/Woodville Road James Ruse Drive Silverwater Road Hill Road Homebush Bay Drive. 2.2 Seek the approval of the SMC environmental manager to use additional roads. 2.3 Where feasible, do not permit site traffic movements through residential streets. Where this is not possible avoid movements during out-of-hours periods or peak times. Traffic management provisions 2.4 Seek road occupancy before undertaking any work requiring the need to excavate, disturb, remove, interfere, pump water into, or form a connection with a road. 2.5 Develop a specific Traffic Management Plan (TMP) covering controls relevant to the location and O&M activity taking place. The TMP will be prepared in accordance with the Traffic Control and Work Site Manual (Roads and Maritime, 2010) and quality assurance specification G10: Control of Traffic (Road and Maritime, 2010) and will include: Layout of plant, any required exclusion zones, loading areas and circulation requirements. Site arrival and pre-notification plans. Traffic volume estimates including vehicle type, frequency and timing of arrival to and departure from site. Traffic control plans showing access arrangements and the details of signs and devices. Vehicle management and movement plans showing entry and exit points. Controls to prevent traffic queuing on public roads. Pedestrian and cyclist management plans including diversions and temporary provisions to guide people through work areas. Measures to manage other road users including lane closures, diversions, and temporary speed restrictions.

141 4 Existing environment Appendix F of the approved project EIS describes the urban design for the upgraded M4 Motorway. 4.1 General characteristics The asset footprint is located within the urban environment of western Sydney. The landscape character of the area surrounding the M4 Motorway corridor can be characterised into seven zones as shown on Figure 4.1. The zones comprise a mixture of residential, commercial and industrial values. The zones in the east around Homebush are typically more commercial and industrial in character and therefore typically less sensitive to change and visual impact. Conversely, the western zones comprise more residential values and features that make them more sensitive to change and visual impact. 4.2 Urban design The WestConnex Urban Design Framework (Roads and Maritime, 2013) defined the built form objectives and provisions for the concepts of upgrading the M4 Motorway under the WestConnex scheme. As a result, the motorway has been upgraded to: Integrate sustainable principles into the planning and design while ensuring that a natural systems approach was adopted Create a strong, simple, legible and inspiring integrated engineering, urban design and environmental solution Minimise impacts on the local community while responding to their concerns and issue through developing a responsive design outcome Transform spaces into places and encourage improved lifestyle opportunities Create a bold language that provides identity to the motorway with a high-quality design. 4.3 Landscaping and planting Section 7 of Appendix F of the approved project EIS details the urban concept design and associated planting and landscaping strategy and principles, which include: Woodland/Cumberland Plain woodland: planted on new batter slopes and areas beyond floodplains/ creeks Riparian/river flat forest: used to reinforce creek and river lines Figs: new plantings at key locations to reinforce the existing planting and maintain local identity Indigenous shrubs: on batters, in narrow planting beds, and areas where trees cannot be planted close to the motorway Native grasses and tussocks: used as mass planting in key locations and as part of the median enhancements to improve overall setting and amenity Median enhancement: including streetscape improvements and enhancing median treatments to include eucalypts with an understorey of native shrubs, groundcover and/or tussocks. Also, the remnant native vegetation within the corridor has been retained and enhanced where feasible. Section 7.6 of Appendix F of the approved project EIS provides additional detail on the planting species mix.

163 4 Existing environment Appendix G of the approved project EIS describes the surface waters and hydrology local to the asset. 4.1 General characteristics The asset is located on the southern side of the Parramatta River estuary crossing the A Becketts Creek, Duck Creek, Duck River, Haslams Creek, and Powells Creek sub-catchments, all of which drain to the Parramatta River, which in turn drains into Sydney Harbour. Figure 4.1 shows the location of the 12 watercourse (and reaches) crossed by the asset. 4.2 Flood risk The asset footprint is located on flood prone land. The largest flood event that could occur across the asset footprint (known as the probable maximum flood level) could be up to about 18 metres deep where the asset crosses Reach E. However, the probability of such an event occurring is remote. A more realistic potential is for each of the 12 water courses to flood to a depth of between four and 16 metres (refer to Table 8.28 in the project EIS). This is the modelled flooding that would occur from a storm that typically occurs once every five years, known as the 5% annual exceedance probability (AEP). The asset would have no measurable impact on flood risk in the area as a result of: Widening and augmenting A Becketts Creek between Good Street and Woodville Road Enlarging the Good Street bridge waterway area Carefully positioning and streamlining the viaduct piers Providing the following flood immunity protection in the design: Five years for the open drains. 10 years for pipes and pits. 50 years for culverts and surcharge structures. 100 years for culverts and non-surcharge structures. 10 years for the pavement. One year for the gross pollutant traps. 100 years to the outfall channels. One year for the cycleways. 4.3 Water quality The water quality of the estuary and the associated sub catchments is generally poor due to the commerce and industry in the area. It is characterised by low dissolved oxygen (DO), low ph, high turbidity, nutrient loading (nitrogen and phosphorous), high algal concentrations and blooms, and the presence of pathogens such as faecal coliforms. The recorded water chemistry also exceeds the aquatic health ecosystem guideline limits for south-east estuaries in Australia as developed under the Australian and New Zealand Water Quality Guidelines for Fresh and Marine Water 2000: Volume 1 the Guidelines (ANZEEC, 2000). The poor quality has limited the recreational use of the estuary. It has also led to the Government advising on people limiting their consumption of fish and prawns from the area s recreational sports fishing ground, while placing restrictions on aquaculture in the area.

164 4.4 Groundwater Water was recorded at depths of between 0.1 metre and 14 metres below Australian height datum (AHD) in The groundwater across the asset footprint was assessed as being broadly consistent, characterised as: Being fresh to brackish, typical of the Ashfield shale in which it is located Having an oxidation-reduction potential. Non-potable groundwater is likely to be present in the alluvium, shale, and sandstones that underlay the asset footprint. Figure 4.1: Watercourse locations Sydney Motorway Corporation M4 Widening Motorway: OEMPSP4: surface water quality & hydrology management sub-plan Page 14 of 31

165 Figure 4.2: Acid sulphate soils 4.5 Acid sulphate soils Acid sulphate soils are potentially present along the entire asset corridor, particularly along existing drainage and creek lines. If these soils are exposed to the air the oxidation process forms sulphuric acid that can wash out and impact on the receiving environment affecting groundwater, surface water, soils and the built environment. Figure 4.2 (above) shows the location of the potential acid sulphate soils in relation to the asset. 4.6 Contaminated land The asset passes through a developed urban environment that comprises a mixture of land uses. Over the past 150 years industrial and commercial land uses have given rise to the potential risk of encountering contaminants. Table 4.1 lists the key land uses and the associated contaminants of potential concern that may have impacted the Asset footprint. Table 4.1: Areas presenting a high or high-to-moderate contamination risk Location Land use and contaminants of potential concern Pitt Street to Church Street Battery recycling depot: potential for heavy metal contaminants and low ph. Church Street to Deniehy Street Cement bound asbestos fragments were observed beneath the M4 Motorway to the northern of A Beckett Street and the corner of Alfred Street. On the eastern side of the James Ruse Drive Junction in a landscaped area beneath the M4 Motorway a grassed over stockpile (about 60 metres by 20 metres by two metres) was observed in weathered portions of the stockpile to contain cement bound asbestos containing materials and potentially acid sulphate soils. Additionally the fill in these areas may contain other contaminants including hydrocarbons, Sydney Motorway Corporation M4 Widening Motorway: OEMPSP4: surface water quality & hydrology management sub-plan Page 15 of 31

166 Location Land use and contaminants of potential concern pesticides and heavy metals, and possible acid sulphate soils (in the stockpile at James Ruse Drive). A section of Duck Creek beneath the M4 Motorway and James Ruse Drive junction was observed to be heavily contaminated by rubbish as well as potential sewage/leachate. The source of this was not identified. There is potential for a range of contaminants including hydrocarbons, heavy metals, asbestos, polycyclic aromatic hydrocarbons (PAHs) and nutrient contaminants. Junction Street to Silverwater Road On the northern side of the M4 Motorway between Junction Street and Newton Street North is a soil and brick recycling facility; this was historically used as a landfill site. To the east of Stubbs Street there is evidence of fill materials (earth mounds, concrete rubble) along the vegetation strip. Waste odours were also noted in the eastern most portion of this area. Landfill and fill materials have the potential for a variety of contaminants including hydrocarbons, pesticides, heavy metals and asbestos, as well as explosive and toxic landfill and volatile organic fugitive gases. Silverwater Road to Homebush Bay Drive On the vegetation strip between Wetherill Street and Day Street South many of the mature trees are either distressed or have died. On the southern side of the M4 Motorway, to the east of Hill Road, between the M4 Motorway and Parramatta Road an area of open space has about 10 partially vegetated stockpiles over an area of about 50 metres by 20 metres. Fill materials included soils, brick, concrete and timber. On the southern side of the M4 Motorway between Birnie Street and Homebush Bay Drive, fill materials were observed in the vegetated strip between Parramatta Road and the M4 Motorway. To the east of Homebush Bay drive a portion of the open space area is used as a recycling centre (fill soils and trees). Fill materials have potential for a variety of contaminants including hydrocarbons, pesticides, heavy metals and asbestos. 4.7 Wetlands The 12 watercourses crossed by the asset classify as low-value highly disturbed coastal freshwater wetlands of the Sydney Basin. Ducks Creek is the only crossing where there is some potential for wetland birds to occur along the riparian (river) corridor, despite the habitat being highly modified in the local area. The only other aspect that is not highlighted in the EIS is the important wetland areas to the north of the M4 Motorway associated with the Sydney Olympic Park west of Hill Road. This area contains groundwater dependent ecosystems, and supports various threatened flora and fauna including a notable population of green and golden bell frog and golden orb spider, which are endangered at the State level and vulnerable at the Commonwealth level. This wetland is supported and supplied by Haslams Creek. 4.8 Changes introduce under water quality plan and monitoring program Under MCoA B7, SMC was required to prepare and implement a water quality plan and monitoring program to support construction of the upgrade of the M4 Motorway. This is to remain in place for a minimum of one year after the upgraded asset is operational. The purpose of the plan and program is to ensure the surface, groundwater and wetland values of the area are protected (refer to section 3.1 above). If impacts are identified after one year of monitoring, the will continue monitoring for a further two years or until the affected waterways and/or groundwater resources are certified by an independent expert as being rehabilitated to an acceptable condition. The monitoring shall also confirm the establishment of operational water control measures (such as vegetation swales). Annex A contains a copy of the water quality plan and monitoring program for operations.

The key steps will include: The use of spill kit material once the area is made safe. Contain the spill within the pavement area if possible. Install containment measures comprising sandbags and booms to prevent migration to the stormwater drainage. Cap outfall points to prevent offsite discharge of polluted water if required and feasible. Potentially drain ponds following heavy rainfall and collect the water for testing and offsite disposal where feasible. Remove any polluted water using a licenced company. Skim oil sheens from the surface of the water quality pond if required. Sydney Motorway Corporation M4 Widening Motorway: OEMPSP4: surface water quality & hydrology management sub-plan Page 19 of 31

170 Step Requirement Responsibility 1.4 Notify NSW EPA and the Councils of the incident and work in collaboration during the clean-up. 1.5 Post event, test the water quality collected in the stormwater management system under the specifications of the ANZECC guidelines (refer to section 3.2.3). Where there are trigger exceedances, collect and pump water offsite for treatment and disposal to a licenced facility. Only start discharge once the testing confirms that the above guideline values have been met and approval has been sought from the NSW EPA. SMC/ SMC/ Note: direct seepage, spills, contaminated water, firefighting water or other water that contains pollutant concentrations above the background concentrations will be directed into separate sumps with pump-out facilities. It will not be discharged to the stormwater system without the approval of NSW EPA and WaterNSW. Spill prevention: material and chemical storage 1.6 Store materials more than 50 metres from a surface watercourse and away from any location where stormwater will be diverted offsite with a direct access to surface or groundwater. Retain material safety data sheets (MSDS) onsite. Also ensure they are available via a 24-hour contact number. 1.7 Maintain access to spill prevention kits onsite ensuring they are included in all operations and maintenance vehicles and within the maintenance depot. 1.8 Protect all stormwater and surface drains before starting any site activities requiring the use of chemicals or fuels, or involving ground clearance or excavation work. 1.9 Ensure that spills are contained and cleaned up as soon as practical notwithstanding the associated health and safety requirement in handling and managing chemicals and fuels Ensure that all chemicals, fuels, dangerous goods and other potentially polluting materials are stored within the maintenance depot. This extends to storing all such materials on hardstand within an area that is bunded to 110 per cent of the capacity of the stored materials and 120 per cent of the volume of the largest contained for smaller packaged storage. Ensure that all drainage within chemical and fuel storage areas is self-contained to prevent any offsite migration. Spill prevention: refuelling 1.11 Ensure that all chemical and fuel transfer, maintenance, loading and unloading, and application activities, or any activity that could result in a spillage, takes place within a bunded and contained area. The bund needs to be capable of capturing 110 per cent of the contained chemical or fuel volumes and 120 per cent of the volume of the largest contained for smaller packaged storage Ensure that a person will be in attendance when vehicle refuelling takes place and that spill kit provisions are on hand and kept on all machinery and vehicles that require refuelling. Spill prevention: pesticide management 1.13 Notify the public ahead of using pesticides Check licencing controls governing pesticide management to ensure that pesticides are not used without licencing authorisation Ensure pesticides are not applied within 50 metres of a surface watercourse or in a location that would allow them to transfer to a watercourse.

Erosion and sediment control devices maintenance and management 2.11 Remove sediment from control devices following a major rainfall event and/or when required Ensure that the collected water contained in control devices and excavations is only discharged after testing. Where required, contain, test and subsequently treat the water to confirm its suitability for discharge in accordance with the ANZECC guidelines (refer to section 3.2.3). Road sweeping and cleaning 2.13 Ensure the motorway and road margins are dry swept regularly and kept clear of debris including; vehicle waste, solid waste, sediment, sand, soil, clay or stones Monitor and clean all sediment traps and pits when they are 60 per cent full. Stockpile management 2.15 Install erosion and sediment control measures at stockpile areas based on the provisions included the Management of Urban Stormwater: Soils and Construction (Landcom, 2004, refer to Control 2.1 to Control 2.8). Ensure all stockpiles are: Maintained on hardstand Fenced Surrounded by drainage diversions No greater than 2.5 metres in height Stored as far as is reasonably practical from the stormwater drainage and surface watercourses and at least 50 metres from surface water features Covered as appropriate, and vegetated/stabilised if they are to be retained for more than three months. Vegetation establishment 2.16 Inspect the areas of landscaping and vegetation cover, introduced in upgrading the M4 Motorway to prevent soil erosion, once every month for the first year of operation. If there is evidence of erosion, consider additional remedial actions. Preference will be given in the first instance to natural controls (i.e. additional remedial planting), followed by manmade controls such as geotextile fabrics. Continue inspections after one-year in locations where there is evidence of erosion in the first year until a point in time where the area is established Adopt Control 2.16 where land will be cleared in the future. This will ensure the effectiveness of any associated landscaping and vegetation cover introduced to remediate the cleared area.

183 1 Introduction 1.1 Purpose and application This Water Quality Plan and Monitoring Program (WQPMP) describes how the impacts from the M4 Motorway: Pitt Street at Parramatta and Homebush Bay Drive at Homebush on surface and groundwater quality will be monitored. It describes how the requirements of CoA B7 will be met and identifies the frequency for the compliance reporting and independent auditing. SMC, through the O&M Contractor, will continue the monitoring for at least one year following the completion of construction. If impacts are identified after one year of monitoring, the O&M Contractor will continue monitoring for a further two years or until the affected waterways and/ or groundwater resources are certified by an independent expert as being rehabilitated to an acceptable condition. The monitoring shall also confirm the establishment of operational water control measures (such as vegetation swales). This WQPMP has been developed from the Water Quality Plan and Monitoring Program prepared by Rizzani de Eccher Australia Pty Ltd/Leighton Contractors Pty Ltd Joint Venture for SMC prior to the design and construction of the M4 Widening Major Civil Works and approved by DP&E on 27 April The approved construction WQPMP has been amended to focus on water quality during the operation of the M4 Motorway.

185 2.3 Objectives The objectives of the Water Quality Plan and Monitoring Program are: To comply with Condition of Approval (CoA) B7 - Water Quality Plan and Monitoring Program and Project Deed requirements as applicable to the M4 Widening project To provide a methodology for the measurement and assessment of water quality parameters. 3 Potential operation impacts and management measures 3.1 Operation impacts Operation Water quality risks during operation of the M4 Motorway are largely associated with the runoff of pollutants from the road surface. Typically, pollutants associated with road runoff are: Sediments from the paved surface from pavement wear and atmospheric deposition. Heavy metals such as lead, zinc, copper, cadmium, chromium and nickel attached to particles washed off the motorway pavement. Oil and grease and other hydrocarbon products. Rubber particles from wearing off tyres on the road pavement. Brake pad dust which could potentially include asbestos from older brake pads. Nutrients (N, P). These deposits build up on road surfaces and pavement areas during dry weather and can be washed off and transported to waterways during rainfall periods. Material deposited by motorists, such as non-biodegradable litter and food wastes, could also impact water quality, amenity and aquatic ecosystems if transported into receiving waterways. During operation there is also a risk of accidental spillage of fuel, chemicals or other hazardous liquids as a result of vehicle leakage or road incident on the M4 Motorway. While the likelihood of such potential spills would be low, the impact on the receiving environment could be considerable as spills of this nature would pollute receiving waterways if not adequately managed or mitigated Maintenance Water quality risks during maintenance are likely to be minimal and include: Excess rainfall causes erosion Spills of hydrocarbons that occur during maintenance activities Sediment-laden water from cleaning of drainage and sedimentation basins discharged into waterways Fuel spills during refueling of O&M vehicles causes contamination of surface water by hydrocarbons Incorrect storage and handling of fuels and chemicals 3.2 Management measures A series of measures to manage the above impacts to water quality have been included in OEMPSP4: Surface Water Quality and Hydrology Management Sub-plan appended to the OEMP. Provided that those measures are implemented during operation, short term impacts are expected to be manageable and similarly have no material impact on receiving water quality.

186 4 Sampling sites Surface and groundwater sites were determined in the EIS as representative locations to monitor potential impacts from Operations (refer to EIS Appendix 1). These locations will be sampled and analysed for water quality parameters (see section 4) on a monthly basis. Where potential impact occurs following a storm event (i.e. >10mm), water sampling will be undertaken for comparison against baseline data. Refer to Table 4-1 and Table 4-2 for water quality monitoring sample location details.

187 5 Water quality standards and parameters 5.1 ANZECC and pre-construction monitoring Surface water Existing water quality in the Parramatta River estuary is degraded with average concentrations of water quality management parameters being above the ANZECC (2000) aquatic ecosystem health guidelines for south-east Australian estuaries. ANZECC provides a framework for the assessment of water quality in fresh water environments that identifies guidelines that can be used as a yardstick to determine possible risk to the environment. The ANZECC criteria can be used to initiate further investigations into surface water quality impacts from a specific site. In the absence of site specific data the ANZECC default values can be used as a guide until sufficient data is available. ANZECC assumes a steady state condition of creek lines which is problematic when applied to ephemeral creek lines due to the high variability of water flows and conditions which can lead to changes in the physical and chemical properties of the water compared to perennial streams. Water quality was measured as part of the EIS biodiversity assessment (SKM 2014) and the Project s Phase II Contamination and Acid Sulphate Investigation and Assessment (GHD, 2014). Table 8-1 provides the results from the EIS biodiversity assessment which compares 2014 water quality results against the ANZECC water quality guidelines. Table 5-1: Water quality sampling results Parameter ANZECC WQ Duck River Duck Creek Haslams Creek Guideline 2000 (Kay St) Turbidity (NTU) Dissolved Oxygen (mg/l) Dissolved Oxygen (%) Conductivity (ms/cm) Salinity (ppt) ph Groundwater Groundwater monitoring results (see Table 8-1) were observed to be reasonably consistent across the M4 West alignment, and within each of the strata: DO: results range from low to moderate oxygen levels typical of fresh/brackish groundwater. EC: results suggest that the groundwater is generally brackish to saline, which is expected for groundwater in the Ashfield Shale as this unit was formed in a marine environment. ph: readings were generally circum neutral which is typical for fresh/brackish groundwater. Oxidation-reduction potential indicated reducing conditions in many of the monitoring wells while some indicted potential oxidising conditions. During the purging and sampling of the groundwater wells, no obvious visual or olfactory evidence of contamination was recorded, with the exception of BH101 where a slight hydrocarbon odour was noted during the purging and sampling.

188 6 Monitoring 6.1 Surface water The key surface water quality parameters that shall be monitored include: Conductivity (EC us/cm) Dissolved Oxygen (mg/l) Oil and Grease (any visible sheen) Turbidity (NTU) ph (units) Quarterly monitoring of hydrocarbons and heavy metals will be undertaken in addition to the physical parameters listed above. Surface water quality monitoring would be undertaken at the locations identified in Appendix 1 each month using a water quality monitoring probe during operations for the initial 12 months post Construction Completion. Note, in accordance with CoA B7 (f) - if impacts are identified after one year of monitoring, monitoring shall be continued for a further two years or until the affected waterways and/ or groundwater resources are certified by an independent expert as being rehabilitated to an acceptable condition. The monitoring shall also confirm the establishment of operational water control measures (such as vegetation swales); Monitoring will be undertaken for wet events (rainfall events where 10mm or more has fallen or rainfall that has caused runoff from the Maintenance Site) and monthly routine dry weather sampling for upstream and downstream readings. Where there is a difference greater than 20% between upstream and downstream further analysis and investigation will be performed to determine if the changes in water quality relate to operation activities. 6.2 Groundwater Groundwater will be monitored on a monthly basis for the following parameters: Conductivity (EC us/cm) Dissolved Oxygen (mg/l) Turbidity (NTU) ph (units) water level Groundwater will be monitored post rainfall would typically relate to rainfall events where 10mm or more has fallen or rainfall that has caused runoff from the site. Quarterly monitoring of hydrocarbons and heavy metals will be undertaken in addition to the physical parameters listed above. The monthly data will be reviewed to determine any trends. This would include reviewing the data for a variance of 20% from the results identified in Appendix 1 and implementing remedial measures if required.

189 7 Contingency and ameliorative measures In the event that adverse impacts to water quality are identified as a result of M4 West O&M Activities, the QSE Manager will implement mitigation and/or remediation strategies to prevent future impacts. These may include: Implement stop works process in accordance with the OEMP Review and amendment of maintenance methodologies Use of alternative maintenance equipment Focus on stabilising disturbed areas with a cover crop, hydro-mulch, hydro- seeding, topsoil and/or mulch Increased monitoring and surveillance of O&M Activities Remediation of disturbed areas Recommence work once the corrective actions have been implemented and preventative actions determined and agreed 8 Reporting All surface water and groundwater sampling will be recorded on the Water Quality Monitoring Record Form (see Appendix 3) A summary of the water quality monitoring results will be reported as part of the O&M Contractor s monthly Environment Report to SMC. The quarterly compliance reports will also include all water quality monitoring results and will be submitted to the Secretary of DP&E, EPA, WaterNSW and City of Parramatta Council. Also involve Council in any water issues affecting surface waters in the Local Government Area, including atypical results and/or incidents that could substantially reduce water quality or affect the natural riparian environment. Incident reporting will be done in accordance with the OEMP. Sydney Motorway Corporation M4 Motorway: Operational Environmental Management Plan: OEMPSP4 Page 8 of 29 Commercial in Confidence
