B-2 – Area 4 - Assessment of Environmental Effects 23 5. ASSESSMENT OF EFFECTS 5.1 INTRODUCTION This chapter of this sub-AEE contains an assessment of the actual and potential effects of allowing the establishment, operation and closure of the Services Trench and associated pipe bridge infrastructure on the environment. The nature of the activity means those effects are predominantly confined to construction related effects, as once established, the only notable presence of the activity will be the pipe bridges that cross the Ohinemuri River immediately adjacent to existing road bridges. The Services Trench itself will be buried and rehabilitated. In that context this chapter addresses: Construction related effects; Landscape, visual amenity and natural character effects; Effects on rural production; and Historic heritage effects. For each it describes the key findings of the various technical assessments OGNZL has commissioned to address these matters and the additional mitigation measures they consider necessary to ensure the effects of the proposed activities are avoided, remedied, mitigated or offset. It does not address effects on cultural values. They are addressed in Chapter 5 of the Overarching AEE. Nor does it address economic effects and social effects. These are common to the whole project and addressed in Chapter 6 of the Overarching AEE. 5.2 CONSTRUCTION RELATED EFFECTS The key potential effects arising from the construction of the Services Trench are noise, dust generation, sediment runoff, traffic movements and lighting. These are addressed in turn below. 5.2.1 Noise Effects An assessment of the actual and potential noise effects as a result of the Waihi North Project is provided in Marshall Day (2022), a copy of which is provided in Part H of these application documents. Marshall Day (2022) considers that activities associated with the establishment of the Services Trench to be construction noise. To maintain reasonable and acceptable noise levels, Marshall Day (2022) recommends construction and maintenance noise associated with the Services Trench comply with New Zealand Standard NZS
