Adelaide Brighton Cement

In reply to Dr CLOSE (Port Adelaide—Deputy Leader of the Opposition) (25 September 2018). (Estimates Committee A)

The Hon. D.J. SPEIRS (Black—Minister for Environment and Water): I have been advised:

One hour monitoring has never been on Adelaide Brighton Cement's (ABC) licence.

The 24-hour average is considered a more appropriate standard and in line with the National Environment Protection (Ambient Air Quality) Measure. There is not currently a health-based standard for one-hour ground level particular emissions, and one-hour monitoring is more susceptible to fluctuations from traffic and other localised emissions. The monitoring is conducted and paid for by ABC.
