CSP2 Contaminated soil and spoil management The CEMP must include requirements and methods for contaminated soil and spoil management developed EPA Victoria. This must include undertaking a detailed assessment prior to any excavation of potentially contaminated areas to identify location, types and extent of any contaminated land and properties within or adjacent to the Project boundary, and sensitive land uses affected by construction activity outside the Project boundary, and assessing the potential impact for human health, environmental risk and odour. This assessment must include but not be limited to consideration of the following: Potential contamination risks at the former quarry locations and landfills Potential contamination risks associated with any alteration of the 220kV power lines and any other utilities Potential contamination risks associated with any works to the North Yarra Main Sewer Potential contamination risks and waste classification of the sediments in the Maribyrnong River and Moonee Ponds Creek Potential impacts posed by contamination sources adjacent to the northern portal area Presence of soil contamination where excavations are proposed in the South Dynon rail yards construction Amendment made in response to recommendation of Andrew Kalitsis construction,

Noise and vibration monitoring commitments and response protocols for managing noise complaints and remedial action Details of the communication plan to be adopted throughout construction . NVP4 Construction Noise Targets 1 Sensitive reas For ensitive (based on AS/NZS 2107:) implement management actions if construction noise is predicted to or does exceed the internal and external noise levels below, and a noise sensitive receptor is adversely impacted. If construction exceeds the noise levels below: Consider the duration of construction noise Consider the existing ambient noise levels Consult with the owner or operator of the noise sensitive receptor Consider any specific acoustic requirements of land uses listed below To determine whether a noise sensitive receptor is adversely impacted.
