required prior to the review of this Measure, participating jurisdictions are encouraged to undertake more frequent reassessments as resources permit.
          (vii) Where a participating jurisdiction undertakes a reassessment in accordance with subsection (vi), if it is not reasonably practicable for the participating jurisdiction to undertake a quantitative assessment (as described in the Guidance Paper for Desktop Analysis and Investigation Procedures) the participating jurisdiction may undertake a qualitative assessment (as described in the Guidance Paper for Desktop Analysis and Investigation Procedures) based on the type of information outlined in subsections 4(ii) and 4(iii).
5. Prioritisation of Stage 2 Sites for the purpose of selecting sites for air toxic monitoring
 (i) Subsequent to the identification of Stage 2 sites, jurisdictions may establish an order of priority for these sites.  This should reflect the significance of potential health impacts arising from exposure to significantly elevated levels of air toxics.
 (ii) To assist in the prioritisation and to validate the selection of Stage 2 sites, jurisdictions may undertake preliminary monitoring using reference-monitoring methods.  Results of such monitoring can be reported to Council.  It would be expected that such preliminary monitoring would comprise a smaller number of samples than for reference monitoring.
6. Preliminary Monitoring for the Prioritisation of Stage 2 Sites
 (i) Application
 Preliminary monitoring may be used to assist in the prioritisation of multiple Stage 2 sites which have been identified from the initial desk top assessment.
 Preliminary monitoring data cannot be assessed against the monitoring investigation levels listed in Schedule 3, as the limited sampling will not give a fully representative measure of conditions at a site.  The data are to be used only in the prioritisation of sites.
 (ii) Assessment
 Once preliminary monitoring at a site(s) is complete the site(s) may then be assessed and prioritised with other jurisdictional sites as detailed in Schedule 2 to this Measure.
 (iii) Sampling and analysis for preliminary monitoring
 Sampling and analysis methods used for preliminary monitoring of air toxics must be as detailed in Schedule 3 to this Measure.
 Sampling for preliminary monitoring should attempt to identify the peak concentrations at the site(s).  Thus sampling should take place during the time of year when maximum air toxic(s) concentrations for the source(s) under consideration are expected.  As a minimum, sampling must be carried out every second day over two consecutive weeks.
 (iv) Applicable Parts
 Siting of equipment for preliminary monitoring is as detailed in Clause 10 of this Measure.
 Data from preliminary monitoring must be reported as detailed in Part 2, Reporting of Monitoring of Air Toxics of Schedule 4 to this Measure.
7. Screening Procedure – Discontinuance of Monitoring at Stage 2 Sites
         (i) This section sets out the screening procedure for discontinuing monitoring
