Lighting Assessment WAI-985-000-REPLC-0019_Rev 0.Docx Waihi North Project Page 27 of 35 21/06/2022 Assessment of Environmental Effects: Lighting REVISION: 0 - Final Figure 18: Processing Plant Area - Existing Lighting View 4 Figure 19: Processing Plant Area - Existing Lighting View 5 A recent review was undertaken of the existing lighting to improve performance, energy efficiency, operating life, and adverse effects. The review recommended the replacement of existing lamp technologies (high pressure sodium, metal halide, and fluorescent) with modern LED technology. It also recommended the use of appropriate luminaire selection and installation practices to minimise adverse effects such as upward light spill, reflection off walls/roofs, and glare. 3.6.2 Proposed Lighting It is reasonable to expect that the expanded and reconfigured Processing Plant and Water Treatment Plant areas will be illuminated using modern lighting design principles to minimise adverse lighting effects. Improved lighting would be installed along the existing conveyor, at the crusher and at the new SAG & Ball Mill.
