Lighting Assessment WAI-985-000-REPLC-0019_Rev 0.Docx Waihi North Project Page 21 of 35 21/06/2022 Assessment of Environmental Effects: Lighting REVISION: 0 - Final 3.5 NORTHERN ROCK STACK 3.5.1 Existing Lighting Minimal permanent lighting exists in the area of the proposed Northern Rock Stack (NRS). Lighting is associated with the existing conveyor directly to the south of the proposed NRS. The lighting consists of building and plant located bulkhead and floodlight luminaires similar to those shown on the elevated conveyor in Figure 9. Lighting is also installed around the existing workshop structure and at the Company owned single storey dwelling at 699 Golden Valley Road. 3.5.2 Proposed Lighting The existing workshop structure, fuel bowser, and grease storage facilities will need to be relocated approximately 160 south west of their present location (reference Figure 10). The permanent lighting associated with the conveyor, loadout, workshops, and office blocks will be maintained as part of these works. Artificial lighting will be required to enable rock stacking operations to occur outside of daylight hours. Preparatory and operational works for the NRS, and rock disposal activities will occur during the following hours: • Monday-Saturday 7 am to 10 pm*. * Note: Planned works are not proposed between 7pm and 10pm however OGNZL may need to do so in certain circumstances. Lighting associated with works between 10pm and 7am are expected to be of a similar type to that required during the “normal’ operational period. Lighting to support rock stacking operations is likely to consist of the following: • Mobile lighting plant. o Typically, these would consist of diesel-powered LED lighting plant, with 3No. to 6No. LED floodlights mounted on 9m extension poles (Reference Figure 6 for a typical configuration). Luminaires would typically be aimed at a high angle to the ground to provide broad lighting coverage across the rock stacking area. Where practicable, lighting towers would be aimed into the rock stack rather than outwards towards the site boundary. o Mobile plant location and orientation will vary over time in response to rock stacking activities and locations. o OceanaGold has a Standard Operating Procedure for “Towing and Setting up Lighting Plants”. The procedure includes a note “Do not shine towards a public road or buildings”.
