throughout NSW during 2002, have contributed to the ozone and particle pollution events observed during 2002. However, for ozone in particular, anthropogenic emissions are sufficient to generate exceedences o f the NEPM standards. Levels o f carbon monoxide, nitrogen dioxide, sulfur dioxide and lead continue to be well below Air NEPM standards. Programs under the Governments air quality management plan, Action for Air, are designed to move NSW towards ozone levels that will achieve compliance with the NEPM goal. The NEPM goal provides an additional impetus for the implementation of strategies and a useful benchmark against which programs to manage the air environment can be assessed. It is too early in the NEPM process to fully evaluate its effectiveness. The review scheduled for 2005 may be the appropriate vehicle for considering this issue. It should also be recognised that there is a danger that the effectiveness o f the NEPM will be undermined if, through its continued expansion or the introduction o f new air quality-related NEPMs (for example the proposed Air Toxics NEPM), monitoring requirements continue to increase. Air quality monitoring requires considerable capital investment and ongoing resources and jurisdictions may find it increasingly difficult to fully commit to such requirements without compromising some programs. PART 4 - REPORTING REQUIRED BY THE NEPM___________________________________ In t ro du c t io n The goal o f the Air NEPM is to meet the NEPM standards (within the maximum number o f allowable exceedences) by 2008. Under the NEPM the various jurisdictions (states and territories) were required to prepare a Monitoring Plan to meet the monitoring requirements detailed in the NEPM. NSW s approved Air NEPM monitoring plan outlines the monitoring network for each o f the required pollutants and is available on the EPA website at <www.epa.nsw.gov.au>. The investment required to implement the plans fully is such that the various jurisdictions are staging the establishment o f new sites and the operation o f new campaign sites. The NSW plan is scheduled to be fully implemented by January 2005. For NSW, where new stations are not yet established or where new instruments have not been deployed for the full 2 0 0 2 calendar year, this is noted in the attached tables. Under the NSW Air NEPM Monitoring Plan, monitoring sites have been distributed to provide a reasonable coverage o f the population while capturing the spatial variability o f pollution events. The monitoring network covers a population o f about 4 million in the greater metropolitan area o f the Sydney, lower Hunter and Illawarra regions. The current monitoring in regional NSW covers an additional population o f about 140 000. Information about the characteristics o f individual monitoring sites and generic information about the exposed population is given in the NSW Monitoring Plan, available on the EPA website <www.epa.nsw.gov.au>. Results Data from relevant monitoring stations are presented in tabular form below to enable an evaluation of whether the NEPM standards and goal were met at each monitoring station. The standards, with accompanying definitions and explanations, appear in Schedule 2 of the NEPM. For averaging times shorter than one year, compliance with the NEPM goal is achieved if the standard for a pollutant is exceeded on no more than a specified number o f days in a calendar year (one day per year for all pollutants except PM 10, which may be exceeded no more than 5 days per year) and at least 75% o f data is captured in each quarter. The sites nominated in the NSW NEPM Monitoring Plan form a subset of the current NSW EPA air quality monitoring network. The following tables report on the performance against the NEPM standards for all sites nominated in the plan. The data presented in the following tables are for the calendar year 2 0 0 2 . All PM 10 data presented in the following tables have been measured by the TEOM method. There has been no temperature adjustment applied to these data. The data are presented in greater detail in regular quarterly air quality monitoring reports prepared and published by the NSW EPA and available from <www.epa.nsw.gov.au/air/datareports.htm>. The more detailed compliance report for this year can be found on the EPHC website.
