3.1          ENVIRONMENTAL CONTROLS
All Kane projects require the development of a project specific Environmental Management Plan. This plan will
be developed with consideration to the site specific requirements and to ensure the project complies with EPA
guidelines and council bylaws. The project’s exposure to weather during demolition and construction emphasises
the need for rigorous management, specifically relating to water run-off and storm water control. Please note
some of the key risks and controls proposed for this project:

 ENVIRONMENTAL RISKS AND CONTROL

 RISK             SOURCE             CONTROL

 Noise               Plant             Plant /machinery maintained in accordance with manufacturer
