The Environmental Protection and Biodiversity Conservation Amendment Bill 2013 (Cth) was introduced into the House of Representatives on 13 March 2013. It proposes to amend the Environment Protection and Biodiversity Conservation Act 1999 (Cth) to expand the Environment Minister’s power to assess and approve CSG and large coal mining developments that have a significant impact on an environmentally significant water resource. There are concerns about the constitutional validity of the Bill and that the proposed amendments will frustrate development of major projects by extending the approval process.
