Family Court scrapped

Despite overwhelming opposition from Australia’s family law specialists and advocates, the federal Liberal-Nationals government and cross benchers scrapped the Family Law Court and subsumed it into the circuit courts last week.

Despite taking action to prevent coal-seam gas miner Metgasco from disposing of potentially polluted wastewater into the Casino Sewerage Treatment Plant (STP) the Environment Protection Authority (EPA) has flagged the possibility of the water being used for agricultural irrigation in the future.

The EPA made the comment in a letter written to the Environmental Defenders Office (EDO) earlier this month, which was acting on behalf of Lock the Gate Northern Rivers (LTGNR).

The letter, written by EPA’s north coast region manager Brett Nudd and addressed to EDO lawyer Sue Higginson, admitted that 1.36 megalitres of potentially contaminated water had been unlawfully released into the Richmond Valley Council’s (RVC) STP.

The letter confirmed the NSW Office of Water’s view that the disposal of water via an STP was ‘inappropriate’ and advised RVC not to process any further water through its STP. But the reason given was a technical one, saying that the liquid for disposal didn’t constitute ‘human septage/effluent’.

It went on to say, ‘Metgasco has also been advised that the water contained in its storage ponds cannot be disposed of via a STP. Further, the produced water needs to be assessed against the EPA’s Solid and Liquid Waste Classification Guidelines to identify lawful disposal pathways’.

But the letter also said, ‘if coal-seam gas produce water is managed appropriately and not cross-contaminated with drilling fluids or other related compounds, there is potential for this water to be sustainably utilised as a resource for agricultural irrigation. The produced water would need to be analysed to ensure it consistently meets ANZECC Water Quality Guidelines.’

The suggestion has rung alarm bells with LTGNR spokesperson Boudicca Cerese, who says experiments with disposal of produced water in Queensland have been very concerning.

‘The Queensland government gave licence approval to a CSG miner there to release wastewater into the Condamine River at elevated levels of heavy metals without apparent consideration of the cumulative impact of such releases over time,’ she told Echonetdaily.

‘Heavy metals are known to bioaccumulate in fish.

‘The industry is relying on the water being treated and used but we’re seeing that reverse osmosis, which removes the salt, doesn’t necessarily remove the heavy metals and other chemicals. They’re just making it up as they go along,’ she said.


Support The Echo

Keeping the community together and the community voice loud and clear is what The Echo is about. More than ever we need your help to keep this voice alive and thriving in the community.

Like all businesses we are struggling to keep food on the table of all our local and hard working journalists, artists, sales, delivery and drudges who keep the news coming out to you both in the newspaper and online. If you can spare a few dollars a week – or maybe more – we would appreciate all the support you are able to give to keep the voice of independent, local journalism alive.


  1. The sociopathic nature and pure unbridled insanity of the minds behind the EPA and the Metgasco CEO’s the organisation serves is now compellingly confirmed.

    • ‘Government is the shadow cast by big business’ (John Dewey). It needn’t be that way, of course, and I’m sure Brett Nudd would decry any attempt to characterise his agency as Metgasco’s shadow, but it appears the EPA is precisely that. Intended or not, the EPA protects the miners’ interests by turning a blind eye to repeated and grave acts of environmental vandalism (acting only when EDO’s lawyers compel it to), and by assuming the function of media outlet for the miners, concocting spin on the miners’ behalf (eg, ‘all you have to do is reconceive of the poisonous water as an agricultural resource!!). They are, in effect, co-conspirators with the miners, and – unless something is done – they will facilitate the robbery of our common wealth, leaving us with poisoned water and dead landscapes in return. Get angry, people. We won’t get another chance. And Mr Nudd, I know from personal experience that acting on conscience is a difficult thing to do for a public servant, but make no mistake: the lives of generations of people hang in the balance.

  2. Absolutely unbelievable! Just when it seems that critical mass has moved towards an intelligent and responsible approach to CSG mining and Fraccing (ie, disallow it until it is proven safe, which cannot happen, because it simply is not…!), along comes this inexplicably ill-considered notion from the Environment Protection Authority, seemingly in favour of the CSG polluters pouring their poisons all over our food chain. Can it be possible that those same people entrusted with the protection of our environment (yes, that is that Department’s role) have somehow managed to avoid educating themselves on this issue?

    In order to ensure that the “coal-seam gas produce water is managed appropriately and not cross-contaminated with drilling fluids or other related compounds” (excuse me???), just who would be responsible for financing the analysis of this water “to ensure it consistently meets ANZECC Water Quality Guidelines”? Metgasco and other CSG polluters??? … I’m guessing not!
