    EIS environmental impact statement: a document prepared to detail the expected environmental, social and economic effects of a development, and state commitments to avoid, mitigate or satisfactorily control and manage any potential adverse impacts of the development on the environment2. In the ACT, an EIS is required for proposals in the impact track as per Section 123 of the Planning and Development Act 2007.

    milliGauss one thousandth of a gauss. Gauss: unit of magnetic induction in the centimetre- gram-second system of physical units. One gauss corresponds to the magnetic flux density that will induce an electromotive force of one abvolt (10-8 volt) in each linear centimetre of a wire moving laterally at one centimetre per second at right angles to a magnetic flux. One gauss corresponds to 10-4 tesla (T), the International System Unit. The gauss is equal to 1 maxwell per square centimetre, o
