This page applies to those projects requiring a NS174A SER under Part 5 of the EP&A Act.

Where the NS174A SER demonstrates that impacts will be minor and predictable, no additional documentation would be needed to demonstrate compliance with the requirements of the EP&A Act. Adequately trained individuals, with a good understanding of the project and the receiving environment, should be able to undertake the evaluation outlined in the NS174A SER without the need to consult specialists.

Most environmental assessments will be in the form of a NS174A SER. In some cases, such as major projects, the environmental assessment will be in the form of a review of environmental factors (REF). These projects should be referred to Ausgrid's Environmental Services.
