the air:
 (a) is to be measured at performance monitoring stations; or
Note   Because the concentrations of different pollutants vary across a region, it would not be necessary or appropriate to co-locate the measuring instrumentation for all pollutants at each performance monitoring station.
 (b) is to be assessed by other means that provide information equivalent to measurements which would otherwise occur at a performance monitoring station.
Note   These methods could include, for example, the use of emission inventories, windfield and dispersion modelling, and comparisons with other regions.
12 Accreditation of performance monitoring
 (1) Subject to subsection (2) the operator of a performance monitoring station must be accredited by the National Association of Testing Authorities.
 (2) The operator may apply an equivalent system for ensuring adequate monitoring, quality assurance, and validation procedures.
13 Location of performance monitoring stations
 (1) To the extent practicable, performance monitoring stations must be sited in accordance with the requirements for Australian Standard AS/NZS 3580.1.1:2016 (Methods for sampling and analysis of ambient air – Guide to siting air monitoring equipment). Any variations from AS/NZS 3580.1.1:2016 must be notified to Council for use in assessing reports.
 (2) Performance monitoring station(s) must be located in a manner such that they contribute to obtaining a representative measure of the air quality likely to be experienced by the general population in the region or sub-region.
 (3) To the extent practicable, performance monitoring stations must be operated in the same location for at least 5 years unless the integrity of the measurements is affected by unforeseen circumstances.
14 Number of performance monitoring stations
(1) The number of performance monitoring stations must be based on determining the potential population at risk.
(2) In high risk areas, additional performance monitoring stations may be needed if determined by relevant participating jurisdictions.
(3) Fewer performance monitoring stations may be needed where it can be demonstrated that pollutant levels are reasonably expected to be consistently lower than the standards specified in this Measure.
(4) Subject to subsections (1) to (3), the number of performance monitoring stations for a region with a population of 25,000 people or more must be at least the next whole number above the number calculated in accordance with the formula:
              1.5P + 0.5
           where P is the population of the region (in millions).
Note   To ensure national consistency, the determination of risk shall be undertaken in accordance with any procedures or methods agreed by participating jurisdictions.
15 Trend stations
 (1) A number of performance monitoring stations in each participating State and participating Territory must be nominated as trend stations.
 (2) The number of performance monitoring stations to be nominated as trend stations must be sufficient to monitor and assess long term changes in
