Due to the limited biodiversity values of the site a BDAR waiver request was submitted to the Department of Planning Industry and the Environment (DPIE), however, this was rejected and a full BDAR assessment is required. This project is deemed to be state significant development and therefore the project will be determined under Section 4.12(8) of the NSW Environmental Planning and Assessment Act 1979 (EP&A Act) and Schedule 2 of the Environmental Planning and Assessment Regulation 2000. One native plant community, PCT 835 Forest Red Gum - Rough-barked Apple grassy woodland on alluvial flats of the Cumberland Plain, was recorded and approximately 0.04 hectares (ha) mapped within the north western corner of the site. This vegetation constitutes the River-flat Eucalypt Forest of the New South Wales North coast, Sydney Basin and South East Corner Bioregions, which is listed as endangered under the NSW Biodiversity Conservation Act 2016 (BC Act). The patch of PCT 835 in the north western corner of the site is in moderate to good condition and represents the only native plant community, and therefore the only vegetation zone, within the Project Site. One BAM plot has been collected by an accredited assessor within this vegetation zone, returning a vegetation integrity score of 27.4. The remaining majority (14.4ha) of the site comprises developed land and planted non-native vegetation. The assessment reveals that the proposed development will require the removal of the 0.04ha patch of PCT 835 or River-flat Eucalypt Forest that is listed as endangered under the BC Act. This impact has been assessed in accordance with the BAM, resulting in an offset requirement of one ecosystem credit for PCT 835. At the time of writing, the offset obligation will require the purchase and retirement of one ecosystem credit or payment of $19,993.96 (ex GST) into the Biodiversity Conservation Fund. No threatened species or their habitats have been recorded within the Project Site and therefore no species credits are required. No impact avoidance measures are possible for the proposed development. Mitigation measures have been presented to reduce the potential for indirect impacts on biodiversity values adjacent or downstream of the Project Site. The proposed development is not likely to have a significant impact on any matters of national environmental significance listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).
