National Environment Protection (Ambient Air Quality) MeasureTechnical Paper No. 8 – Annual ReportsIn addition, Clause 17(3) specifies that jurisdictions may provide an evaluation of a region as awhole against the standards. A region is in compliance if, and only if, every performancemonitoring station in the region meets the standards and goal. Based on this definition, thecompliance status of the region as a whole can be stated in the last column of Tables 1 to 6(Performance against the standards and goal). A broader description of regional assessmentmay be included under section D.Clause 14(3) of the AAQ NEPM allows fewer monitoring stations to be used in regions where itcan be demonstrated that pollutant levels are reasonably expected to be consistently lower thanthe NEPM standards. The PRC has therefore developed screening procedures (described inTechnical Paper No. 4) which specify the circumstances under which monitoring is notrequired in a region that is otherwise covered by the NEPM. The arguments justifying theabsence of monitoring in these regions are detailed in the approved monitoring plans. Theseregions should be listed in the Annual Report separately from Tables 1 to 6 with a note thatthey are in compliance under Clause 14(3) that the pollutant levels are reasonably expected tobe consistently lower than the NEPM standard.Air quality assessment using methods other than physical monitoring are also possible. TheAAQ NEPM in Clause 11(b) permits the use of alternative means that provide informationequivalent to measurements, which would otherwise occur at a performance monitoringstation. Such alternatives must be documented and formally approved in monitoring plans. Ifthis were to occur, the data should be reported in the same format as for physical monitoring.The yearly information, for each pollutant and performance monitoring station in each regionthat must be included in this section, consists of:1. the percentage of data available for the calendar year as well as for each calendar quarterfor each performance station;2. the number of exceedence days for each performance station;3. the annual mean concentration for pollutants with a 1-year standard; and4. the compliance status for each pollutant at each performance monitoring station in relationto the standards and the goal, as "met", "not met" or "not demonstrated."The proposed formats for each of the AAQ NEPM pollutants are shown in Tables 1 to 6.Page 8
