2 REGULATORY FRAMEWORK
2.1 INTRODUCTION This PCA has been prepared in accordance with the regulatory framework outlined below and with reference to the following guidelines:
x Guidelines for Consultants Reporting on Contaminated Sites (NSW Office of Environment and Heritage, 2011); and x Managing Land Contamination, Planning Guidelines, SEPP 55 – Remediation of Land (NSW Department of Urban Affairs and Planning & NSW Environment Protection Authority (EPA), 1998).
2.2 ENVIRONMENTAL PLANNING AND ASSESSMENT ACT 1979 As described in Section 1, Shenhua Watermark is seeking State Significant Development Consent under Division 4.1 of Part 4 of the EP&A Act for the Project. The determining authority is the Minister for Planning & Infrastructure. The EP&A Act provides an important role in the management of land contamination is NSW by incorporating mechanisms to ensure that:
x Planning authorities consider contamination issues when they are making rezoning and development decisions; x Local councils provide information about land contamination on planning certificates that they issue under Section 149 of the EP&A Act; and x Land remediation is facilitated and controlled through State Environmental Planning Policy 55 - Remediation of Land (SEPP 55).
2.3 CONTAMINATED LAND MANAGEMENT ACT 1997 The Contaminated Land Management Act 1997 (CLM Act) regulates significantly contaminated sites in NSW. The general objective of the CLM Act is to establish a process for investigating and (where appropriate) remediating land that the NSW Environment Protection Authority (EPA) considers to be contaminated significantly enough to require regulation.
2.4 STATE ENVIRONMENTAL PLANNING POLICY 55 SEPP 55 – Remediation of Land (SEPP 55) was enacted to provide a state wide approach to the remediation of contaminated land for the purpose of minimising the risk of harm to the health of humans and the environment. Managing Land Contamination, Planning Guidelines, SEPP 55 – Remediation of Land (the Guidelines) have been prepared to assist in managing land contamination in NSW in accordance with SEPP 55. Specifically, the Guidelines provide:
x Information to assist in the investigation of contamination possibilities;

3 EXISTING ENVIRONMENT
3.1 TOPOGRAPHY AND CATCHMENTS The Project is located within the Gunnedah Basin which is one of the main coal basins within NSW. The closest township to the Project is the village of Breeza to the east of the Project Boundary. Gunnedah is located approximately 25 km to the north north-west of the Project Boundary, whilst Tamworth is located approximately 50 km to the east north-east. The Kamilaroi Highway and Werris Creek - Moree Railway Line run adjacent to the Project Boundary in the east and form part of an important road and rail network that provides access throughout the region. The Gunnedah Shire is located approximately 324 metres (m) above sea level on the Liverpool Plains of the Namoi River Valley. The region is generally flat with only 1% of the Gunnedah Shire recording land slopes greater than 15 degrees and within which the Project is generally located. Topography is variable across the Project Boundary. Topographic highs can be found in the vicinity of the Eastern, Western and Southern Mining Areas including Mt Watermark (512 m Australian Height Datum (AHD)), Smokey Point (447 m AHD), Black Mountain (393 m AHD) and an unnamed topographic high within and to the north of the Western Mining Area, which is referred to as ‘Springhurst Hill’ by local residents. The black soil plains are located outside of the Project Boundary to the south and south- east. Gently undulating cleared grasslands (approximately 310 m AHD) dominate the central and western portions of the Project Boundary. The Project Boundary is located within the catchment of the Mooki River, a tributary of the Namoi River (see Figure 2). The headwaters of the Mooki River originate on the northern slopes of the Liverpool Ranges and Coolah Tops, flowing in a northerly direction to the Namoi River north-east of Gunnedah. Several ephemeral first and second order streams traverse and drain the land within the Project Boundary, including Watermark Gully, Native Dog Gully and a series of smaller unnamed watercourses.
3.2 LAND USE The local area within the vicinity of the Project Boundary has had a long history of agricultural production. In more recent years, major cropping areas have shifted towards establishment on the black soil plains while grazing has been transferred to land situated on the lighter red soils and ridge country, as seen within the Project Boundary. Today the key enterprises within the Project Boundary encompass a range of sheep and cattle grazing and cropping, including wheat, sorghum and barley. The current state of the land within the Project Boundary is a reflection of past agricultural practices, including vegetation clearing, weed invasion, pasture improvement, altered natural drainage, feral animals, erosion and salinity. The majority of the land is comprised of large expanses of grassland interspersed with isolated remnant woodland patches along boundary fences, road verges, on hills and steep slopes.

3.3 LAND OWNERSHIP Land ownership within and surrounding the Project Boundary is shown on Figure 3, whilst Figure 4 provides an inset of the landownership within the village of Breeza. All of the land within the Project Boundary is owned by Shenhua Watermark with the exception of a small parcel of Crown land on Mt Watermark. Private freehold land primarily surrounds the Project Boundary with the exception of the fore mentioned and Breeza State Forest to the south-west, which is owned by the State and managed by Forests NSW. Property titles and boundaries of land holdings referred to throughout this PCA are presented in Figure 5.

4 METHODOLOGY
To assess the history and land use of the Project Boundary, a desktop study of the following available information was undertaken, including:
Review of a soil landscape map to identify any land registered as ‘Disturbed’; Review of historical aerial photos to identify past land use and potentially contaminating activities; and Search of the register of the NSW Contaminated Sites Notified to the EPA (EPA, 2012).
The findings of the desktop study are provided in Section 5. As part of the property acquisition process by Shenhua Watermark, inspections were undertaken to develop an understanding of the existing condition of each property. The inspections focused on the state of repair of structures, fixtures and appliances, identification of any occupational health and safety hazards, fencing, paddocks, dams and vegetation. The results of each inspection were presented in property condition reports. A Historic Heritage Impact Assessment was undertaken by AECOM Australia Pty Limited (AECOM) to determine the potential impacts of the Project on historic heritage items identified within and adjacent to the Project Boundary (AECOM, 2012) (see Appendix Q of EIS). As part of the assessment, a field survey targeted for sites of historical significance was undertaken within the Project Boundary. Although the property condition reports and the Historic Heritage Impact Assessment were not undertaken for the purpose of assessing contamination, some of the observations presented throughout each of the reports were considered relevant to identifying areas of potential contamination throughout the Project Boundary. For this reason, these reports were reviewed and observations considered relevant to this PCA were included.
The findings of the review of available property condition reports are presented in Section 6 and the findings of the review of the Historic Heritage Impact Assessment are presented in Section 7. A summary of the areas of potential contamination identified by this PCA is provided in Section 8.

5 DESKTOP STUDY
5.1 REVIEW OF SOIL LANDSCAPE MAP The soil landscapes within the Project Boundary have been mapped by the NSW Department of Land and Water Conservation incorporating the Soil Conservation Service of NSW at the scale of 1:100,000 (Banks, 1995). The soil landscape map was reviewed for this PCA to identify any areas mapped as disturbed terrain within the Project Boundary, which indicates that the natural soil profile in the area has been disturbed by human activities, and may have been backfilled with imported filling materials (e.g. land fill sites). Two small areas located in the eastern portion of the Project Boundary were identified as disturbed terrain. The disturbed areas are located in the eastern portion of the Moondyne property and the western portion of the Lilyfield property.
5.2 HISTORICAL AERIAL PHOTO REVIEW Aerial photos for 1954, 1967, 1976, 1989, 1998, and 2003 were investigated to identify previous land use and potentially contaminating activities throughout the Project Boundary. The aerial photos are presented in Figure 6 to Figure 11. The results of the historical aerial photo review are presented in Table 1. The results of the historical aerial photo review indicate that since 1954, the area within the Project Boundary has generally been cleared, displaying evidence of heavy agricultural activity such as cropping, erosion bunds, and farm dams. Two potential quarries were observed in the western portion of the Project Boundary between 1954 and 1967. Vegetation cover was observed at the surface of these potential quarries in the 1989, 1998, and 2003 aerial photos, indicating that excavations ceased at these potential quarries sometime between 1976 and 1989. A third potential quarry was identified in the southern portion of the Project Boundary in the 1976 aerial photo. Scattered objects of various sizes were observed between the two potential quarries located in the western portion of the Project Boundary in the 1989 aerial photo and adjacent to a patch of bushland in the southern-most portion of the Project Boundary in the 1998 aerial photo.

6 REVIEW OF PROPERTY CONDITION REPORTS
As part of the property acquisition process by Shenhua Watermark, inspections were undertaken to develop an understanding of the existing condition of each property. The inspections focused on the state of repair of structures, fixtures and appliances, identification of any occupational health and safety hazards, fencing, paddocks, dams and vegetation. The results of each inspection were presented in property condition reports. The property condition reports were reviewed in order to provide an indication of potential contamination based on available information. The potential sources of contamination that were identified are presented in Table 2. Table 2 Review of Property Condition Reports

7 REVIEW OF HISTORIC HERITAGE IMPACT ASSESSMENT
As part of the Historic Heritage Impact Assessment undertaken by AECOM, a field survey targeted for sites of historical significance was undertaken within the Project Boundary in April 2011 and February 2012. The Historic Heritage Impact Assessment was not primarily conducted to identify areas of potential contamination and the personnel undertaking the inspections were not qualified to undertake contamination assessments. However, the results of the inspections were reviewed in order to provide additional potential contamination information based on available information. The potential sources of contamination that were identified during the review of the Historic Heritage Impact Assessment are presented in Table 3. Table 3 Review of Historic Heritage Impact Assessment
Property Name Potential Sources of Contamination In-ground septic tank, depression with building rubble at the surface (adjacent to the Shar septic tank) Demeter Rubbish tip containing rubbish dumped by the previous owner for nearly 100 years The Wilgas Waste rock pile next to disused coal mine, rail siding (associated with the coal mine) Clift Coal Mine, waste rock pile (adjacent to the coal mine), rubbish tip (appears to be Cardington located within the former mine entrance depression) Keinghton Machinery sheds Cloveneden External toilet with pressure tank located above Inverness Slaughtering shed Watermark Demolished (bulldozed) brick kiln and associated shed, two poultry yards Linavardi Poultry shed Barwo Farm machinery within and surrounding sheds Construction materials bulldozed into a pile (including materials potentially containing Flakenhoe asbestos), workshop

8 IDENTIFIED POTENTIAL CONTAMINANT SOURCES
On the basis of the available site history and a review of observations presented in the property condition reports and during the Historic Heritage Impact Assessment, the principle sources of potential contamination identified are presented in Table 4. It is noted that many of the property condition reports were undertaken for properties that are only partially located within the Project Boundary, therefore the potential sources of contamination listed in Table 4 for those properties may not be located within the Project Boundary. Table 4 Potential Contaminant Sources
Type of Potential Sources of Contamination Contaminant x Potential impact to soils throughout the Project Boundary due to long term agriculture land use x Potential chemical mixing areas (herbicide mixing). Usually located near chemical storage and machinery storage areas (Dixie1, Tathra1, Keinghton, Deregistered and Springhurst1, Lilyfield, Boondah1, Stafford / Part Stafford1 and Urubula1) concentrated chemical x Sheep showers / dips identified at Elsdon1, Inverness, Springhurst1, Lilyfield, use The Wilgas, Demeter, Flakenhoe, Molonga, Elsdon, Gleneyre1 and Lauriston1 x Possible sites for sheep dips (consider known woolsheds as a likely source) at Shar, Boondah1 and Barwo. x Rubbish tips at Linavardi, Keinghton, Cardington, Springhurst1, Lochiel East1 and Demeter, Monivae1 and Urubula1 x Scattered objects of various sizes (potential dumped waste / storage area) at 1 Imported filling and The Wilgas and Urubula , identified in the aerial photo review (see waste materials Section 5.2) x Potential quarries at Moondyne, Lilyfield, The Wilgas and Linavardi x Former coal mines, sidings, and associated stockpiled materials at The Wilgas and Cardington x Septic tanks and disposal areas, notably the septic tanks in poor condition at 1 Sewage / sewage Dixie and Marney treatment and disposal x The “long drop” toilet at Inverness and the sewage disposal location at Santa Capri
x Former piggeries / pig sheds at Elsdon, Springhurst1, Lilyfield, Monivae1 and Lauriston1 Livestock slaughter x Meat house at Marney operations x Slaughtering shed at Inverness x Poultry shed at Linavardi

9 MITIGATION AND MANAGEMENT
Although multiple potential sources of contamination were identified within the Project Boundary, the majority of the potential sources of contamination identified are associated with structures and activities likely to be identified on other properties with an extensive history of agricultural land use. The results of this PCA identified the need for an additional investigation to be undertaken to assess the extent of contamination throughout the Project Boundary. It is recommended that a contamination investigation should be undertaken by a licensed contractor to further assess the extent of contamination prior to the disturbance of the sources of contamination, with consideration of the potentially contaminated areas outlined in Section 8. Following the detailed contamination investigation, a remedial action plan should be prepared for the Project to manage any identified contamination.

10 LIMITATIONS
This PCA was prepared by Hansen Bailey to provide a preliminary indication of contamination conditions within the Project Boundary based on available information at the time of the assessment and does not constitute a detailed site investigation undertaken by a licensed contractor. A detailed site investigation should be undertaken by a licensed contractor to assess the extent of contamination prior to the disturbance of the sources of contamination. The property condition reports and Historic Heritage Impact Assessment reviewed in Section 6 and Section 7 were not prepared for the purpose of a contamination assessment and therefore the observations made were not targeted towards potential contaminant sources.
