Extreme smoke pollution in Launceston City area in May result of burning gorse on private property, not Forestry Tasmania burn-offs, says State Govt

Posted by gmarkets on 3 September, 2007

Smoke pollution over Launceston last May was not caused by Forestry Tasmania burnoffs, said Mr Doug Parkinson, Leader of the Government in the Council, answering a question from Independent MLC and Launceston Mayor Ivan Dean in the Tasmanian Legislative Council on 22 August 2007. Gorse, not forestry: Parkinson told the Council that the answer involved a lot of figures and charts. “Smoke which affected Launceston during the period outlined by Hon Ivan Dean MLC is most likely to have come from burning of gorse on private property at Breadalbane and Hadspen/Carrick which went on for a week or so,” he said. “A satellite image taken at the time that smoke and fog caused the closure of Launceston Airport shows that the smoke from Forestry Tasmania burns in the central north and north-east of Tasmania was travelling away from Launceston.”

Supplementary Information The following supplementary information was provided by the government: “The majority of PM10 exceedences in Launceston occur in winter, and are generally associated with emissions from domestic solid fuel burning during the coolest months of the year. Table 1, which is when exceedences of the National Environment Protection Standard are more likely to occur. Despite the reduction in the number of wood heaters in Launceston, domestic solid fuel burning is still the main source of PM10 emissions. Emissions from paved and unpaved roads and motor vehicles are the next largest contributors. Industrial emissions contribute approximately 6 per cent to PM10 emissions in Launceston during the coolest six months of the year

For comparison Table 2 below shows the estimated relative contributions to the Launceston atmospheric PM10 load from identifiable sources averaged across the entire year.

It is possible that other particulate sources such as fuel reduction and regeneration burns outside the Launceston City Council area may also contribute to PM10 levels in Launceston.”
