Introduction Proposed Lynwood Quarry, Marulan 1.0 INTRODUCTION Readymix Holdings Pty Limited (Readymix) proposes to establish a hard rock quarry on its land to the west of Marulan in the Southern Tablelands of New South Wales (NSW) (refer to Figure 1.1). The proposed Lynwood Quarry (the project) will be located approximately 160 kilometres southwest of Sydney and approximately 27 kilometres northeast of Goulburn. The Readymix land holding totals approximately 1000 hectares, the majority of which is a grazing property known as ‘Lynwood’. An aerial photograph of the project area is included as Figure 1.2. The project area not only contains a substantial, high quality hard rock resource, but also has ready access to key transport infrastructure. The Main Southern Railway bisects the project area and the Hume Highway adjoins Readymix’s southern boundary (refer to Figure 1.2). Readymix has a sound knowledge of the hard rock resource, due to both an extensive exploration drilling program and experience from operation of the existing Johniefelds quarry, located on Brayton Road approximately 2 kilometres north of the project area. The proposed quarry is intended to provide a long-term supply of high quality construction material into the Sydney, regional and local markets. The proposed supply to the Sydney market will replace Readymix’s current production from the Penrith Lakes Scheme which is likely to be exhausted around 2010. The proposed quarry is planned to produce approximately 5 million tonnes per annum (Mtpa) with an expected life of in excess of 90 years. Approval will be sought for an initial period of 30 years. 1.1 PROJECT AREA The project area is currently used for cattle grazing, except for the transport corridors and an area on the eastern boundary of the property which is leased by Readymix to Orica Explosives and is occupied by a bulk storage depot. A substantial portion of the northern part of the project area is occupied by woodland, with the majority of the remainder being cleared grazing land with scattered patches of remnant woodland. The project area is surrounded primarily by grazing land, with a rural residential area under development adjacent to the northeastern boundary and existing residential areas associated with the township of Marulan further to the east. The project area is situated in an area that supports fragmented woodland, open forest and derived pasture, consistent with much of the Southern and Central Tablelands of NSW. The project
