 This is not unusual, as several renewable energy projects were declined resource consents (see Awhitu, Mokau hydro, Mount Cass, Te Waka).Contact Energy appealed the decision to decline the consent application and presented a substantially revised proposal, especially with regards to the limestone geology and sediment control.One of the consenting authorities, Horizons Regional Council, stated that consents should not have been declined on the basis of discharge of contaminants to groundwater, and that the consents should be granted.
