A Preliminary Biodiversity Assessment (ERM 2014) previously completed for the Oakey Solar Farm identified that a targeted biodiversity field survey of the gen-tie route would be required once the route options had been further refined to determine if any specific referrals triggered under the Nature Conservation Act 1992 (‘NC Act’) or the Environmental Protection and Biodiversity Conservation Act 1999 (‘EPBC Act’) would be required. This report provides a summary of the results from targeted field surveys for the north and south gen-tie route options and PV Facility and identifies the regulatory implications under the NC Act and the EPBC Act on the Oakey Solar Farm, from here on referred to as the Project. The scope of the targeted field surveys was to survey for protected plants in accordance with Flora Survey Guidelines – Protected Plants, 2014 (as a portion of the area is identified within the protected plant trigger mapping); perform opportunistic searches for signs and habitat features for threatened flora and fauna under the NC Act and EPBC Act and assessment of habitats and vegetation communities. The field surveys identified that the gen-tie route north, gen-tie route south and PV Facility Study Areas are highly disturbed, however support some biodiversity values recognised under the NC Act and EPBC Act. Nature Conservation Act (1992) The Study Areas provide potential suitable habitat for threatened fauna species koala (Phascolarctos cinereus) and Condamine earless dragon (Tympanocryptis condaminensis). No listed threatened flora species were identified from field surveys and an exempt clearing notification (protected plants) form is required to be completed and submitted to the Queensland Department of Environment and Heritage Protection. Breeding habitat for birds and amphibians (colonial breeders) was identified in the Study Areas. Under the Nature Conservation (Wildlife Management) Regulation 2006, a Species Management Program (SMP) is required where impacts to breeding habitat for birds or amphibians (colonial breeders) is unavoidable. Where breeding habitats can be avoided and not impacted during construction activities, there will be no requirement for a SMP. Environmental Protection and Biodiversity Conservation Act 1999 The Study Areas provide potential suitable habitat for threatened fauna species koala (Phascolarctos cinereus) and Condamine earless dragon (Tympanocryptis condaminensis). Based on the MNES Significant Impact Guidelines 1.1 (DoE 2013) and the implementation of controlled mitigation measures, including minimising the establishment or spread of weeds as well as minimising the risk of fauna mortality as ENVIRONMENTAL RESOURCES MANAGEMENT AUSTRALIA 0195672_09/FINAL/20 JANUARY 2017 I described in Section 4.3, the Project is not considered to have a significant impact on the koala or Condamine earless dragon. Indeed, removing cultivation from the proposed PV Facility Study Area and replacing it with a lower impact land use (solar farm), that includes restoring the area to grassland, is likely to have a positive impact to the species. ENVIRONMENTAL RESOURCES MANAGEMENT AUSTRALIA 0195672_09/FINAL/20 JANUARY 2017 II 1 INTRODUCTION Environmental Resources Management Australia Pty Ltd (‘ERM’) has been commissioned by Canadian Solar (Australia) Pty Ltd (‘Canadian Solar’) to assist with obtaining the relevant environmental approvals required for the Oakey Solar Farm which includes construction of a gen-tie route and an approximate 205 ha Photovoltaic (PV) Facility on Lot 1 on RP48454, Lot 7 on RP36475, Lot 8 on RP36475 and Lot 9 on RP36475 at Oakey, Queensland commencing on the corner of Bridge Street and the Old Warrego Highway. Findings of a Preliminary Biodiversity Assessment (ERM 2014) identified that a targeted biodiversity field survey of the gen-tie route would be required once the route options had been further refined to determine if any specific referrals triggered under the Nature Conservation Act 1992 (‘NC Act’) or the Environmental Protection and Biodiversity Conservation Act 1999 (‘EPBC Act’) would be required. For completeness, a targeted biodiversity field survey was also undertaken for the PV Facility. This report provides a brief summary of the results from three targeted field surveys for the north and south gen-tie route options and PV Facility and identifies the regulatory implications on the Oakey Solar Project, from here on referred to as the Project. For the purposes of this report, the PV Facility Study Area is defined as the boundary of the proposed PV Facility which represents an area of 205 ha . The Gen-tie Northern Route (GTNR) Study Area is defined as a linear area approximately 6.3 km in length and 30 m wide, running parallel and north of the Warrego highway (including the Old Warrego highway). The Gen-tie Southern Route (GTSR) Study Area is defined as a linear area approximately 6.1 km in length and 70 m wide running parallel and south of the Warrego highway (refer to Figure 1). ENVIRONMENTAL RESOURCES MANAGEMENT AUSTRALIA PTY LTD 0195672_09/FINAL/20 JANUARY 2017 1 2 BACKGROUND 2.1 PROJECT BACKGROUND On 22 April 2015, RE Oakey Pty Ltd, via ERM, received a Material Change of Use and Reconfiguring a Lot (Dividing Land into Parts by Agreement) Development Permit for the purposes of constructing and operating a staged 80 MW Photovoltaic (‘PV’) solar farm at 1287 Warrego Highway, about 7 kilometres west of Oakey, Queensland. Since the receipt of the Development Permit, Canadian Solar has taken on responsibility for the Project, and is working through the process to obtain the relevant resource and finance arrangements from the Australian Renewable Energy Agency (‘ARENA’), as well as the necessary connection approvals from the energy provider, in order to progress the Project. As part of the initial Project feasibility studies, ERM was commissioned to provide a Preliminary Biodiversity Assessment (PBA) of the gen-tie route linking the solar facility to the Oakey substation, with two alignment options proposed. An Annex attached to the PBA provided an assessment of the biodiversity values of the PV Facility. A preliminary field survey was completed in February 2014 which covered both options for the approximate 7 km length of the road reserve and preliminary observations of the PV Facility. The two alignment options support derived grassland comprising a mix of native and non-native species, with scattered mature eucalypts.
