B-1 - Area 1, Coromandel Forest Park – Assessment of Environmental Effects 90 Actual or Potential Effect Recommended Mitigation / Management Recommended Monitoring / Future Action Additional Measures Proposed by OGNZL Aircraft land/hovering zones are to be maintained to ensure public safety. Aircraft idle times on the ground are kept to a practicable minimum. Locate vent raises away from tramway formations. Vibration Effects of vibration on amenity values during development of the Dual Tunnels and during development of the WUG. None required None required. None. Effects of vibration on fauna in the CFP All blasting within Area 1 associated with the establishment of vent shafts and underground tunnels the peak particle velocity (vector sum) at the surface shall be no more than 15 mm/s for 95% of blast events. Vibration monitoring is proposed. See Archey’s Frog section below. Dewatering and Ground Settlement Effects on surface water due to the Dual Tunnels. Implement the development methodology identified as appropriate for this purpose in Valenza (2022) (see Part H of these application documents). Periodic reporting to WRC and the Expert Panel on tunnel progress, key monitoring data and the effectiveness of the The Valenza (2022) methodology requires Installation of monitoring instruments and hydraulic testing in zones of potential impact in None.
