Waste report: coal seam gas industry poses enormous challenges for Queensland A report prepared for the federal Department of Environment and Energy says the coal seam gas (CSG) industry in Queensland has made the state “a unique hazardous waste jurisdiction”. The report, ‘Hazardous Waste in Australia’, says the CSG industry provides enormous waste management challenges not present in other states and territories.
CSG produces close to 20% of Qld waste “CSG wastes make up around 11% of apparent Qld waste generation in 2014-15, but if apparent waste generation is adjusted for obvious reporting errors … this CSG figure is closer to 20%.
“These figures include only what has been subject to hazardous waste tracking. Vast volumes of salty extraction waters, which either do not arise into offsite management infrastructure or are not regulated as hazardous waste, are not tracked but have been estimated to be around 25 million tonnes per annum (in 2009) in the Surat Basin alone.
“One of the smaller CSG projects in the Bowen Basin is expected to produce up to 0.6 ML of brine a day, and some 60 000 tonnes of salts and heavy metals over the life of the project,” the report says. The CSG extraction process produces a range of hazardous wastes including alkalais, non-toxic salts, other residues and mercury. Apart from mercury wastes, they comprise solids and liquids from ‘drilling

A hazardous waste report says very large quantities of CSG extraction waters are likely to be barely visible in (hazardous) waste tracking data. The water is often sprayed on roads as a ‘dust supressant’ – even on sealed roads. The unmarked truck above, minus registration plates, was seen spraying near the Santos Fairview gasfield in April.

Contaminants such as salt, radium and heavy metals are likely to drain into local waterways and end up in drinking water.
