Lighting Assessment WAI-985-000-REPLC-0019_Rev 0.Docx Waihi North Project Page 32 of 35 21/06/2022 Assessment of Environmental Effects: Lighting REVISION: 0 - Final Views of mobile lighting associated with TSF3 would be occur from a broad range of locations (Views 18 to 21). Direct glare effects could be visible from relatively distant locations (several kilometres) and would be in the context of a predominantly rural environment with limited lighting from the existing mine and localised farm building lights. The extent of effects will depend upon the perspective of the viewer, the viewing location, and the type of controls placed upon the use of mobile lighting plant. For those residents who value the existing darkened night environment, such effects could range from “Moderate-Low” to Moderate-High”. Mobile lighting plant has the most potential to cause adverse effects as the luminaires are traditionally installed with their light producing faces aimed at a high level to the ground (Reference Figure 6) - to flood an area with light. Permanent lighting may result in glare effects if it is of the type as presently installed on site, however lighting designed to minimise adverse effects should result in minimal, if any, direct glare effects. The actual effects will depend upon the visibility of the lighting from outside of the site. Compliance with the recommended limits for luminous intensity in AS/NZS 4282 will depend upon the actual luminaires used, their location, and orientation. Vehicle headlight, taillight, task, and safety lighting, whilst often excluded from Plan Rules, can result in adverse effects – particularly in rural environments. With respect to glare, the extent of any effects will depend upon lighting intensity, visibility from outside of the site, and rapid intensity change (i.e., flashing) Lighting associated with vehicles moving within the WUG SFA, and between the SFA and the Portal, will be visible from outside of the site at the north end of Willows Road until the noise bunds have been constructed and proposed planting mitigation has grown sufficiently to directly screen vehicles from view (reference: Boffa Miskell, Waihi North, Landscape Assessment, Appendix 3: Visual Simulations, Views 1 and 2). Vehicle lighting will also be visible from more remote locations with views of the rock stack. Movement associated with head, tail, and task lighting would be visible along with rotating or flashing security beacons. The extent of effects will depend upon the perspective of the viewer, and the viewing location. For those residents who value the existing darkened night environment, the changing lighting effects could range from “Moderate- Low” to Moderate”. Lighting associated with vehicles travelling to and from the proposed explosives magazine may be visible from some locations on Highland Road (Visual Simulation View 5), however an average of only two trips per night shift for security checks are expected to occur after dark. It is not known whether permanent lighting associated with the magazine will be visible from locations in Highland Road, however, it is reasonable to expect that any such lighting would be designed to minimise effects from external viewing locations. Similar vehicle lighting effects to those expected at the WUG, would be expected at the NRS and TSF3. Those at the NRS would initially be against the background of existing conveyor lighting such that effects should be “Low”. Vehicle lighting effects associated with TSF3 are likely to be visible from multiple locations with views of the area. Movement associated with head, tail, and task lighting would be visible along with rotating or flashing security beacons. The extent of effects will depend upon the perspective of the viewer, and the viewing location. For those residents who value the existing darkened night environment, the changing lighting effects could range from “Moderate” to Moderate-High”.
