Introduction This report has been prepared on behalf of Wilpinjong Coal Pty Ltd (WCPL), a wholly owned subsidiary of Peabody Energy Australia (Peabody) to present the results of an assessment of the road transport implications of a proposal to extend the open cut operations at the Wilpinjong Coal Mine (WCM) for an additional operational life of approximately seven years. WCM is an open cut coal mining operation located approximately 40 kilometres (km) north-east of Mudgee in central New South Wales (NSW) (Figure 1-1). The Wilpinjong Extension Project (the Project) would involve extension to existing open cut pits, development of a new open cut pit, continued extraction of run-of-mine (ROM) coal, continued use of the WCM Coal Handling and Preparation Plant (CHPP) and general coal handling and rail loading facilities and other existing and approved supporting mine infrastructure. This study has been undertaken with reference to the road transport components of the Secretary’s Environmental Assessment Requirements (SEARs).
