She is a certified environmental professional with seven years of experience across civil construction, tunnelling and mining. • James. B Skurupey, MSc (ENVR), CEnvP, has 17 years of experience in the environmental To encourage transparency and accountability regarding water quality monitoring, upstream and downstream NTU data are made publicly available each week. Additionally, after a rain event (0.98 inches [25 mm]/24 hours or 0.59 inches [15 mm]/60 minutes), a rainfall trigger inspection report is sent to the Regulator. These reports are also made publicly available and include inlet and outlet NTU, clarity and pH results from each sediment treatment pond on site. In-stream static sampler NTU, total suspended solids and pH, and sediment deposition results in the Mimi Wetland are also made available. The ESC requirements of the project are managed on-site by the ESC team lead with two senior ESC advisors. This core team works closely with two ESC supervisors and a team of skilled labourers split across the active construction zones. The ESC team collaborates closely with the ecology and engineering teams to develop construction methodologies that meet the requirements of all disciplines. The process to develop effective ESCs on-site is thoroughly planned, reviewed and implemented. A “feedback loop” process is used to allow learnings to be incorporated back into management plans to ensure continuous improvement. Te Ara o Te Ata is using a holistic approach to environmental management. While working in a challenging environment, the Alliance has used an adaptive strategy for erosion and sediment controls. Te Ara o Te Ata will have quantifiable benefits that stretch beyond the delivery of a road. These gains include innovation and knowledge-sharing with the industry (Figure 9), social and cultural benefits, and positive ecological outcomes that will leave a lasting legacy on the Taranaki region.
