initial assessment should:
  1) Identify and locate sources of air toxics emissions; and
  2) Determine which locations in the jurisdiction have potential to experience significantly elevated ambient levels of air toxics.
 (iii) In making such assessments jurisdictions should consider:
  a) potentially significant emission sources of air toxics such as:
                 i) highly trafficked roads;
                 ii) cumulative impacts associated with multiple sources including major industry;
                 iii) clustered small to medium enterprises; and
                 iv) areas where there is a high level of wood heater use;
  b) existing monitoring data;
  c) inventory and modelled data;
  d) local meteorological, geographical and seasonal effects;
  e) dispersion and airshed modelling; and
  f) other relevant information.
 (iv) It is the responsibility of jurisdictions to take into account all available relevant information on emissions of air toxics when making this initial assessment.
 Information sources and tools that jurisdictions may wish to use in the identification of Stage 1 sites include:
• monitoring data;
• emissions inventories including the National Pollutant Inventory;
• available licensing information from environmental protection agencies;
• registers of businesses under workplace, health and safety legislation;
• business and domestic activity surveys;
• traffic counts, including nature and volume of traffic;
• business directories;
• local knowledge/observations from jurisdictional officers;
• information about specific local sources of emissions of the air toxics;
• ambient dispersion modelling;
• regional air shed modelling; and
• town planning and development approval information.
 Geographical Information Systems (GIS) software can assist visualisation of this type of information.
 (v) The identification of Stage 1 sites for a particular air toxic does not necessarily imply that it is a Stage 1 site for other air toxics.
 (vi) Jurisdictions must also repeat the desktop assessment of Stage 1 sites to identify additional Stage 2 sites of locations identified as Stage 1 sites no later than the end of the fourth year after the commencement of this Measure.  In undertaking this repeat procedure, jurisdictions must reassess locations within their jurisdiction using the same methodology utilised for the initial assessment.
          (vii) While only one formal repeat assessment of Stage 1 sites is required prior to the review of this Measure, participating jurisdictions are encouraged to undertake more frequent reassessments as resources permit.
          (viii) Where a participating jurisdiction undertakes a reassessment in accordance with subsection (vii), 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 Procedure) 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 3(iii) and 3(iv).
