The extension of the process for environmental approvals was granted following the provision by Gunns of additional information, which seeks to enhance the environmental position of the mill.These more stringent environmental aspects have been proposed by the company following consultation with community and environmental non-government organizations, Gunns writes in a press release."We want to ensure we build this pulp mill using the best-available technology, with the best environmental controls available,” said Gunns Managing Director, Greg L’Estrange.The deadline for approval has been extended to 10 March 2011.
