National Environmental Protection Council annual report 2 0 1 0 2 0 1 184 V ic A IR T O X IC S Victoria Report to the NEPC on the implementation of the National Environment Protection (Air Toxics) Measure for Victoria by the Hon. Ryan Smith, Minister for Environment and Climate Change, for the reporting year ended 30 June 2011. precinct.pdf) Screening for formaldehyde will also be undertaken 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. Repeat identification of stage 1 and stage 2 sites A review of the identification and prioritisation of potential stage 1 (ranking) and stage 2 (exposure) site locations or hotspots for air toxics monitoring was completed in May 2011 using the revised procedures specified by the Air Toxics NEPM. The Air Toxics NEPM (NEPC, 2004) requires jurisdictions to periodically review sources of air toxic emissions and identification of potential air monitoring sites. The review included the analysis of predicted concentrations from modelling using the air pollution emissions inventory, meteorology and population in 2006 for Victoria. In addition, an analysis based only on the air pollution emissions inventory for the Port Phillip Region was conducted. The review found all of the predicted concentrations of ambient air toxics or estimated emissions were below the Monitoring Investigation Level (MIL) specified in the Air Toxics NEPM. Motor vehicle emissions were found to be the major sources at the sites with the highest levels. Based on air pollution modelling, highest predicted concentration relative to each air toxic MIL ranged from 22% for benzene, 15% for formaldehyde, 0.05% and 1.5% for toluene, 0.7% and 2.2% for xylene. Highest benzo(a)pyrene emissions were estimated to be 66% of MIL based on air pollution inventory estimates. Unlike the modelling predictions, the inventory estimates identified one other site for toluene associated with industry emissions in the higher category of 66% of the MIL. The benzo(a)pyrene and toluene sites identified will be considered in future monitoring programs. PART 1 IMPLEMENTATION OF THE NEPM AND ANY SIGNIFICANT ISSUES There was no monitoring of air toxics under the Air Toxics NEPM (AT NEPM) in Victoria in 2010. During 2011, monitoring for benzene, toluene and xylene commenced in residential areas in Tullamarine surrounding a former prescribed waste landfill, and in Dandenong South surrounding a large industrial precinct that includes a current prescribed waste landfill. A review of the identification and prioritisation of potential stage 1 (ranking) and stage 2 (exposure) site locations or hotspots for air toxics monitoring was completed in May 2011. The review found all of the predicted concentrations of ambient air toxics or estimated emissions were below the Monitoring Investigation Level (MIL) specified in the AT NEPM. PART 2 ASSESSMENT OF NEPM EFFECTIVENESS Past air monitoring results generally aligned with the levels estimated in our review of identification and prioritisation of potential stage 1 and stage 2 sites (further information below). The air modelling and air pollution inventory may not capture some specific areas and diffuse sources (such as emissions from some small to medium enterprises) effectively, or estimate the resulting local impact adequately. Therefore, more work is required to understand and evaluate potential impacts from industrial precincts where numerous small to medium enterprises are operating, such as Dandenong South. Identification of sites There were no new AT NEPM monitoring sites identified in Victoria in 2010. Reporting of monitoring of air toxics There was no monitoring of air toxics under the AT NEPM in Victoria in 2010. Reporting on assessment and action if any planned or taken to manage air toxics During 2011, monitoring for benzene, toluene and xylene commenced in residential areas in Tullamarine surrounding a former prescribed waste landfill, and in Dandenong South surrounding a large industrial precinct that includes the current prescribed waste landfill (further information can be found here: www.epa.vic.gov.au/ community_issues/docs/Dandenong-south-industrial http://www.epa.vic.gov.au/community_issues/docs/Dandenong-south-industrial-precinct.pdf http://www.epa.vic.gov.au/community_issues/docs/Dandenong-south-industrial-precinct.pdf http://www.epa.vic.gov.au/community_issues/docs/Dandenong-south-industrial-precinct.pdf
