We are at the beginning of the planning process and have recently commissioned environmental studies as part of preparing the EIS and this includes air studies. The EIS Scoping Requirement is set out by the ACT Government, and this lists the things that the studies must address.
The link to the scoping document is http://www.legislation.act.gov.au/ni/2017-389/default.asp
Baseline air quality findings will be part of the air quality analysis and will be provided in the Draft EIS.
A good example is in Vancouver where they monitor their 25MWe waste to energy plant (which was commissioned back in 1988). There has been no measured effect on the nearby surrounding areas.
It should also be noted that the renewable energy generated from the facility will offset carbon dioxide/emissions from other high carbon content fossil fuels found in power generated in the National Electricity Market (NEM).
