Air Quality Monitoring

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:

The EPA relies on PM10 criteria under the Environment Protection (Air Quality) Policy 2016 and National Environment Protection (Ambient Air Quality) Measure (NEPM). Within these two pieces of legislation, 24 hour averages are defined as calendar day averages calculated from midnight to midnight.
