National Environmental Protection Council annual report 2 0 1 0 2 0 1 1108 N SW A M B IE N T A IR Q U A L IT Y Meeting the AAQ NEPM standards for ozone is a significant challenge for Sydney, given pressures from a growing population, urban expansion and associated increase in motor vehicle use and an increasing trend in domestic emissions of volatile organic compounds (which are precursors of ozone) from sources such as paints, solvents, aerosols, and small engines. The particle (as PM10 and as PM2.5) goals present a similar challenge in NSW, particularly in rural population centres where agricultural activities and a combination of topography, climate and relatively high use of solid fuel heaters produce elevated levels of particles in autumn and winter. NSW has a range of programs in place, which target the primary emission sources of ozone and particle pollution, as determined using NSWs comprehensive air emissions inventory. The AAQ NEPM goals provide an additional impetus for the implementation of strategies and a benchmark to assess programs to manage the air environment. Data from relevant monitoring stations are presented below. 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 of days in a calendar year (five days per year for PM10, one day per year for all other pollutants) and at least 75% of data are captured in each quarter. The data are presented in greater detail at www.environment.nsw.gov.au/aqms/aqi.htm The monitoring plan for NSW is available from www.environment.nsw.gov.au/air/nepm/index.htm CO Carbon monoxide(NEPM standard 8 hours = 9.0ppm) Station Number of exceedences NEPM goal compliance Sydney Chullora 0 met Liverpool 0 met Macarthur 0 met Prospect 0 met Rozelle 0 met Illawarra Wollongong 0 met Lower Hunter Newcastle 0 not demonstrated Data availability criteria were not demonstrated at Newcastle due to technical issues.
