Hydrology, quality and waste management: To protect waterways and waterway function and surface water and groundwater quality in accordance with statutory objectives, to identify and prevent potential adverse environmental effects resulting from the disturbance of contaminated or material and to manage excavation spoil and other waste in accordance with relevant best practice principles SW1 For all precincts (with the exception of the western turnback) design permanent and temporary works and, if necessary, develop and implement emergency flood management measures for the tunnels, tunnel portals, access shafts, station entrances and Arden electrical substation to provide appropriate protection against floodwaters and overland stormwater flows. This would be informed by a flood immunity risk assessment that considers a range of events, and to the requirements and satisfaction of the responsible authority.

Traffic Management Plan (TMP) The TMP would provide the means by which the contractor would minimise disruption to traffic, car parking, pedestrian and bicycle movements during construction. Site Environment Implementation Plans (SEIPs) Site specific plans identifying site-specific environmental control measures to be implemented. Work Method Statements Description of work activities, approvals required and risk assessment and control measures. Records and Checklists Monitoring and inspection records Checklists (e.g. environmental site inspection checklist) Records (e.g. training/competency records, waste transport and disposal certificates). Change Management Revisions to MMRA and contractor documentation may be required as a result of changes in activities and work practices, changes to legislation, risks, or as a result of findings from internal or external audits, incidents or complaints. The contractors' EMS, CEMP and OEMP would be controlled documents and would be developed, approved, implemented and revised in accordance with Table The contractor would be required to submit all major revisions to environmental documentation to MMRA for approval. Major revisions are defined as changes that affect work practices, roles and responsibilities, environmental risks and overall project delivery.
