Lake Macquarie–Wyong air quality

Geographical setting

The local government areas of Lake Macquarie and Wyong are on the central coast of NSW, approximately 100 kilometres north of Sydney.

These areas cover 1,500 square kilometres, with rural valleys to the west and large coastal lagoons to the east. The population of nearly 340,000 is clustered in coastal towns and settlements around the bays and peninsulas.

Major transport routes run north–south and east–west.

Air emission sources

The main sources of air emissions in the Lake Macquarie–Wyong area are from electricity generation plants at Eraring, Vales Point and Lake Munmorah.

Other sources include coal mining, residential wood heating, quarrying, motor vehicles and recreational boats.

Air quality

The EPA commissioned a review of air quality of the Lake Macquarie-Wyong in region, in response to a community request. The review considered data collected by the NSW Government and industry from September 2013 to June 2016. A detailed review of 2014 and 2015 found that air quality was very good to fair 99% of the time during 2014 and 2015, compared to the NSW Air Quality Index.

Lake Macquarie–Wyong Air Quality Annual Reports

The Lake Macquarie-Wyong Air Quality Annual Reports summarise all of the monthly data for the calendar year, as well as trend analysis and compliance with annual average criteria.

Lake Macquarie–Wyong Air Quality Monthly Reports

The Lake Macquarie–Wyong Air Quality Monthly Reports provide a summary of available air quality and meteorological information from industry and government monitoring sites.

Community feedback to the EPA suggests that air quality monitoring data published online by various sources is often complex and difficult for the public to interpret against national air quality standards.

The following reports present complex air quality information in an easy-to-read format. The report format was developed in consultation with councils, community, industry and NSW Health.
