Infrastructure on the farm will be removed when no longer required and the farm property will be returned to pastoral farming. • Remove surface infrastructure at vent raises, restore vent raise footprint and undertake weed control. Rather than replanting within Coromandel Forest Park, natural revegetation will be facilitated through weed and pest control to promote a more robust and complex vegetation community. 8.4 Mitigate The following mitigation measures are proposed to reduce the severity of adverse ecological effects: • Project and engineering actions to reduce the impact of noise and air discharges at Willows Road Farm. These include noise barriers (bunds), installing the external ventilation fan in an insulated shipping container to reduce noise levels, water spray trucks and reseeding the topsoil stockpile to reduce dust. • Project and engineering actions to minimise potential impacts on fauna and habitats within Coromandel Forest Park including use of a small helicopter to reduce noise effects; the vent fan being fitted to base of shaft to reduce noise experienced at the surface; vents constructed from the bottom up to reduce disturbance to the forest, vent 45 A series of sub-management plans will be prepared to guide fauna management prior to and during vegetation clearance at Willows Road Farm, including a Bat Management Plan, Avifauna Management Plan, Lizard Management Plan. The objectives of these plans are detailed in proposed conditions; Part E of the AEE, (Mitchell Daysh, 2022).
