Fremantle Port Inner Harbour and Channel ... - Fremantle Ports

Subsequent to approval of the CAP, Fremantle Ports received two separate approvals underSection 45C of the Environmental Protection Act 1986 to: (i) re-orientate the OffshoreDisposal Area (rationale for this change was provided in Section 4.1.2 of a previousCompliance Assessment Report; Oceanica 2010b); and (ii) amend the duration of dredgingworks from “20-26 weeks” to “up to 30 weeks in aggregate” (EPA 2011a,b). While majordredging works of Phase 1 and Phase 2 were completed within 23 weeks in aggregate, thelatter amendment was required to facilitate the minor backhoe works, comprising excavationof 0.1% of the entire dredge volume (Table 1.1). In line with the intent of a Section 45Capproval, the EPA considered that these changes would “not result in a significant,detrimental, environmental effect in addition to, or different from, the effect of the originalproposal” (EPA 2011a,b). Relevant monitoring requirements remained applicable throughoutperiod of minor backhoe works; and while acknowledging the re-orientation of the OffshoreDisposal Area and extended duration of the program, the CAP remains a valid basis forcompliance assessment.Utilising the CAP and audit table as the basis for assessment, this Compliance AssessmentReport is intended to document the compliance status of the Project against MinisterialStatement 801 for the post-Project completion period November 2011 to November 2012. ACompliance Assessment Report documenting the compliance status of Phase 1 and 2 ofProject works was previously submitted to the OEPA during November 2010(Oceanica 2010b) and 2011 (Oceanica 2011).A summary of compliance is provided in Section 2, which includes the audit table elementsand the status of those elements (Table 2.2). For some audit table elements more details areprovided in subsequent sections and appendices, and these are cross referenced in Table 5.1.More specifically, further detail on the compliance status of the annual survey footprint of theoffshore disposal ground is provided in Section 3. It is also noted that this document reportsresults from additional monitoring activities that are not specific requisites of MinisterialStatement 801; specifically supplementary benthic primary producer habitat (BPPH)monitoring (Section 4).Previous compliance reporting has satisfied the majority of reporting requirements(Oceanica 2010a, 2010b, 2011). The intent of this Compliance Assessment Report is tofacilitate assessment of the remaining compliance status of the Project works againstMinisterial Statement 801 during the period August 2011 to August 2012.2 Oceanica: Fremantle Ports: Fremantle Port Inner Harbour and Channel Deepening, Compliance Assessment Report 2012
