National Environmental Protection Council annual report 2 0 1 0 2 0 1 1 125 W A A M B IE N T A IR Q U A L IT Y Western Australia Report to the NEPC on the implementation of the National Environment Protection (Ambient Air Quality) Measure for Western Australia by the Hon. Bill Marmion MLA, Minister for Environment, for the reporting year ended 30 June 2011. PART 2 ASSESSMENT OF NEPM EFFECTIVENESS The NEPM has provided a focus for air quality issues and guided all jurisdictions to work towards nationally consistent monitoring techniques and reporting. This has culminated in the development and approval of monitoring plans for all jurisdictions, including Western Australia. The AAQ NEPM standards and goals provide an additional impetus for the implementation of strategies and a useful benchmark against which air quality management can be assessed. Air quality management initiatives implemented in Western Australia have placed the state in a favourable position to achieve compliance with the AAQ NEPM goals in most circumstances. Sulfur dioxide and lead have been effectively controlled by regulatory means. Carbon monoxide and nitrogen dioxide concentrations comply with the AAQ NEPM standards by comfortable margins due to improved fuel quality standards, national vehicle emissions standards and control of other sources. Ozone and PM10 remain pollutants of concern in the Perth region and are the focus of attention within the Perth AQMP, particularly the management of domestic PM10 sources. In other regions, PM10 is the pollutant of most significance with respect to the AAQ NEPM standards. The data presented below shows that Western Australia has met the AAQ NEPM goals for all the pollutants in 2010 except for PM10 in Collie. The exceedences were as a result of smoke-haze events, largely from prescribed burning activities. 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 AAQ NEPM. For averaging times shorter than one year, compliance with the AAQ 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 (one day per year for all pollutants except PM10, which may be exceeded no more than five days per year) and at least 75% of data is captured in each quarter. The data are presented in greater detail in 2010 Western Australia Air Monitoring Report, available on our web site at www.dec.wa.gov.au/content/view/3429/1680/ The monitoring plan for Western Australia is available from www.dec.wa.gov.au/content/view/3429/1680/1/9/ PART 1 IMPLEMENTATION OF THE NEPM AND ANY SIGNIFICANT ISSUES Implementation activities may be viewed in two categories: those activities related to implementing the monitoring and reporting protocol of the Ambient Air Quality NEPM (AAQ NEPM), plus other activities associated with the Future Actions listed in the AAQ NEPM Impact Statement those activities within Western Australia (including regulatory activities) designed to ensure that the air quality is in compliance with the AAQ NEPM goal for each of the six pollutants within the specified ten-year period. In the first category, the Department of Environment and Conservation (DEC) has: an air quality laboratory which was fitted out and commissioned during the previous year, providing a centralised facility for servicing, testing and regular maintenance of air quality instruments used throughout the air quality network. The facility is a vital part of a general network upgrade as DEC progresses toward NATA certification. continued to liaise with local governments and other organisations as required to facilitate the positioning and repositioning of fixed ambient monitoring stations made substantial progress towards meeting its goal of receiving NATA accreditation, with all infrastructure upgrades and systems development now complete maintained monitoring of PM2.5 to facilitate the review and potential development of compliance AAQ NEPM standards for this pollutant in the future contributed to the AAQ NEPM review team and the Standards Setting working group. In the second category, DEC has: continued to implement the Perth Air Quality Management Plan (Perth AQMP). The Perth AQMP is a whole-ofgovernment plan aimed at improving and maintaining Perths air quality. Implementation of a number of priority actions within the Perth AQMP has commenced in addition to a number of ongoing programs. There continues to be a major focus on managing emissions from motor vehicles and wood heaters, via the CleanRun and Halt the Haze programs, respectively. DEC continues to investigate and trial a number of monitoring technologies. maintained community access to regularly updated air quality monitoring data via DECs webpage www.dec.wa.gov.au/content/view/3420/1576/
