National Environmental Protection Council annual report 2 0 1 0 2 0 1 1 47 PART 3 JURISDICTIONAL REPORT ON ACTIVITIES UNDER THE NEPM Identification of sites Queensland identified two types of locations as having the most potential for significant population exposure to air toxics: built-up residential areas close to heavily trafficked roads with significant congestion problems (e.g. Woolloongabba); and built-up residential areas close to major petrochemical industries (e.g. Wynnum). Tasmania undertook monitoring at two additional sites in 2010. No other jurisdictions identified any new sites in the reporting period. Reporting of monitoring of air toxics NSW, Queensland, South Australia and Tasmania reported monitoring of air toxics. The results in all cases showed levels well below the monitoring investigation levels. NSW indicated that the results for benzo(a)pyrene, with levels of approximately 65% of the NEPM Monitoring Investigation Level, were the most significant. Tasmania reported that the monitoring was conducted predominantly using passive sampling techniques. Passive sampling allows for the possibility of longer sampling periods which increases the likelihood of detection of these species. In Western Australia, monitoring, as well as the additional complementary air quality studies, indicated that air toxics levels in Perth continued to be low compared to international standards. No other jurisdictions undertook monitoring during the reporting period. Reporting on assessment and action if any planned or taken to manage air toxics Victoria reported that screening for formaldehyde is planned at Tullamarine to evaluate the impacts from the nearby airport formaldehyde emissions. There is no data on formaldehyde levels near a major airport in Victoria. Victoria is also monitoring for a number of air toxics at two sites, one near a former prescribed waste landfill at Tullamarine, the other at South Dandenong which surrounds a large industrial precinct and a current prescribed waste landfill. In response to community concern, the South Australia EPA has worked closely with fuel storage facilities to develop Environment Improvement Programs (EIPs) to reduce emissions from their sites. South Australia is also undertaking a pilot project to develop an air quality management strategy and is currently reviewing the Air Environment Protection Policy to improve general air quality. No other jurisdictions engaged in any specific strategies or actions. Repeat identification of stage 1 and stage 2 sites Queensland identified two new stage 2 sites that are medium density residential areas with the potential for significant population exposure to air toxics from motor vehicle emissions, and lowmedium density residential areas with potential for significant population exposure to air toxics from industrial emissions, respectively. South Australia reviewed its desktop analysis, which resulted in changes to the number of stage 1 sites identified in the first study for the Adelaide airshed. Consequently, the number of stage 2 sites identified in the Adelaide airshed also changed. PART 4 ASSESSMENT OF NEPM EFFECTIVENESS The monitoring investigation levels provide a nationally consistent benchmark for assessing and comparing the concentration of ambient air toxics from diverse monitoring sites. Most jurisdictions agree that the NEPM has been effective in providing an impetus to investigate available data and in identifying locations most likely to experience significant population exposure to elevated levels of air toxics. One jurisdiction identified that the air modelling and air pollution inventory may not effectively capture emissions or resulting local impact from some small to medium enterprises adequately.
