B-6 – Area 6 – Assessment of Environmental Effects 37 3.8 EARTHMOVING EQUIPMENT The construction of the Northern Rock Stack will require a range of earthmoving equipment during its operating life. This includes: 50 to 110 tonne excavators Graders Compactors Service vehicles Bulldozers Water trucks Front end loaders Light vehicles 50 to 80 tonne trucks The number of units will vary over the life of the activity. Various smaller equipment will also be used intermittently such as small excavators, articulated dump trucks, tyre handlers, yard cranes and forklifts. 3.9 LIGHTING Lighting will be established around the NRS to provide for activities outside of daylight hours. The lighting around the rock stack will be relocated as required and as the establishment of the rock stack progresses. Mobile lighting plant will be operated in accordance with OGNZL’s Standard Operating Procedure for Towing and Setting up Lighting Plants. This procedure includes a note to “Do not shine towards a public road or buildings”. All lighting will be designed, located and directed so that the level of artificial lighting measured at the boundary of any privately owned property (or property not subject to an agreement with OGNZL) is no greater than 8.0 Lux.3 3 Note this is consistent with the lighting requirements at OGNZL’s existing mining operations. Refer to section 2 of the AEE for a description of the existing mining activities.
