 If there are regular exceedances at the same site jurisdictions may wish to consider management actions.
Table 2: Monitoring investigation levels
Column 1                                                         Column 2          Column 3                        Goal

Benzene                                                          Annual average*   0.003ppm                        8-year goal is to gather sufficient data nationally to facilitate development of a standard.

Benzo(a)pyrene as a marker for Polycyclic Aromatic Hydrocarbons  Annual average*   0.3ng/m3                        8-year goal is to gather sufficient data nationally to facilitate development of a standard.
Formaldehyde                                                     24 hours#         0.04 ppm                        8-year goal is to gather sufficient data nationally to facilitate development of a standard.
Toluene                                                          24 hours#         1 ppm                           8-year goal is to gather sufficient data nationally to facilitate development of a standard.
                                                                 Annual average*   0.1 ppm
Xylenes (as total of ortho, meta and para isomers)               24 hours#         0.25ppm                         8-year goal is to gather sufficient data nationally to facilitate development of a standard.
                                                                 Annual average*   0.2 ppm

*For the purposes of this Measure the annual average concentrations in Column 3 are the arithmetic mean concentrations of 24-hour monitoring results.
# For the purposes of this Measure monitoring over a 24 hour period is to be conducted from midnight to midnight.

Note 1 - For toluene and xylenes the Annual average and 24 hour monitoring investigation levels have been derived independently for different (chronic and acute) health endpoints.
Note 2 - The 24 hour monitoring investigation levels in table 2 have been derived from health based guidelines of shorter averaging periods.
           * For formaldehyde the health based guideline is 0.08 ppm for a 1 hour averaging period;
           * For toluene the health based guideline is 4 ppm for a 6 hour averaging period; and
           * For xylene the health based guideline is 1 ppm for a 30 minute averaging period.
6. Meteorological Monitoring
 Monitoring of relevant meteorological data will assist in assessing data relative to sources.  Meteorology monitoring stations would need to be set up to obtain data relevant to a Stage 2 site not further than 2km away depending on local site assessment.  Meteorological data, such as wind speed and direction, temperature, relative humidity, and dewpoint temperature, should be recorded wherever practicable.
Schedule 4 Reporting requirements
1. Purpose
 This Schedule sets out reporting requirements for this Measure (refer Clause 13).  The purpose of reporting is to inform the public of progress in the assessment of sites and subsequent monitoring of air toxics.
2. Reporting Requirements
 Jurisdictions are required to report under this Measure to Council on an annual basis.  This report must be submitted to Council by the 30 June next following each reporting year.  Reporting requirements comprise four parts:
• Part 1:  Identification of Stage 1 and Stage
