Introduction 1.1 Purpose of the preliminary site investigation Roads and Maritime Services (RMS) engaged Sinclair Knight Merz Pty Ltd (SKM) under Professional Services Contract (PSC) number 09.2166.2109-0049 to develop the concept design and undertake a review of environmental factors (REF) of the M4 Managed Motorway Project between Strathfield and Lapstone. The project primarily involves the implementation of ITS infrastructure and systems including civil works, to manage the flow of traffic on the M4 Motorway. This report has been prepared in accordance with Section 3.3 of the PSC and SKM’s proposal to provide a desktop contaminated soils investigation report at ramp and widening locations as part of the M4 Managed Motorways project (referred to herein as the site). This report was prepared in parallel with the geotechnical background review to assess potential contamination issues at the site that may have arisen from past and/or present activities undertaken on/and or adjacent to the site which may represent a constraint to the design and construction of the respective project elements. The format for this report generally follows the guidelines as published in the following documents: NSW EPA (2000) Contaminated Sites: Guidelines for Consultants Reporting on Contaminated Sites (NSW EPA, 2000) National Environmental Protection Council (1999) National Environment Protection Measure (Assessment of Site Contamination) Measure 1999 (NEPC, 1999) Australian Standard AS 4482.1-2005 Guide to the investigation and sampling of sites with potentially contaminated soil. Part 1: Non-volatile and semi-volatile compounds (AS 4482.1- 2005). 1.2 Objectives of the preliminary site investigation Specifically, the objectives of this report are to: Identify past and present potentially contaminating activities Identify potential contamination types and location Discuss the site conditions Provide a preliminary assessment of site contamination Assess the need for further investigations Desktop contaminated soils investigation report March 2013 PAGE 1 M4 Managed Motorway – Concept Design & Environmental Assessment 2. Site Information 2.1 Site identification The site encompasses 16 interchanges. Each interchange comprises of eastbound and westbound on and off-ramps. The project site also includes three locations along the 42 kilometres of the motorway between Homebush Bay Drive, Homebush, and Russell Street, Emu Plains, NSW where lane widening is proposed to widen the M4 Motorway. The Australian Map Grid coordinates of the approximate centre of the site are 310339 m E, 6258436 m S. A site layout plan is shown in Figure 1. 2.2 Site zoning and land use The site travels through nine council areas, each with separate Local Environmental Plans (LEP). According to Penrith City Council (LEP 2010), Parramatta City Council (LEP 2011), Strathfield City Council (LEP 2012), Burwood City Council (LEP 2012), City of Canada Bay Council (LEP 2008), and Auburn City Council (LEP 2010) the site is classified as SP2 Infrastructure (classified road), according to Blue Mountains City Council the site is classified as Regional Transport Corridor (road), and according to Blacktown City Council (BLEP 1988) and Holroyd City Council (LEP 1991) the site is classified as 5B Special Uses (arterial road and arterial road widening). 2.3 Acid sulphate soils risk Acid Sulfate Soil (ASS) Risk Maps from the NSW Natural Resource Atlas database were reviewed to ascertain the presence of ASS on the site. Based on this information, areas of ASS risk could occur in the following area: A high probability of occurrence of ASS is present within the soils of the Duck River, approximately 130 metres downstream of the site. The Duck River runs underneath the M4 Motorway at Silverwater. The James Ruse Drive interchange is the closest interchange in relation to Duck Creek. Duck Creek is located approximately one kilometre east of the James Ruse Drive interchange. 2.4 Hydrogeology The direction of groundwater flow could not be definitively assessed based on current information, although the surrounding topography suggests that groundwater would flow towards the waterways flowing across and adjacent to the site i.e. Haslams Creek, Duck River, Parramatta River, Coopers Creek, Ropes Creek, Blaxland Creek, Finlaysons Creek, Pendle Creek, South Creek, Byrnes Creek, Girraween Creek, Blacktown Creek, Eastern Creek, Angus Creek, Claremont Creek, Surveyors Creek, Nepean River, School House Creek and Jamison Creek. A search with the NSW Natural Resources Atlas database identified no registered groundwater wells within the site. Forty-seven wells were registered within an approximate 500m radius of the site. Information on the 47 wells is summarised in Table 1.
