Liddell licenced to emit toxic air pollution 14 times higher than international best practice

AGL’s Liddell power station has been granted an exemption from NSW air pollution regulations and emits toxic oxides of nitrogen (NOx) at up to 14 times the concentration allowable in the United States, documents obtained under Freedom of Information reveal.

The extraordinary exemption permits the 46-year-old coal-fired power station in the Hunter Valley to emit toxic NOx at almost twice the official concentration limit allowed for NSW power stations of Liddell’s age.

“This is one more compelling reason why Prime Minister Malcolm Turnbull should stop trying to find ways to keep this ageing and inefficient power station open,” said Dr James Whelan, researcher with Environmental Justice Australia.

The report obtained under FoI shows AGL Macquarie applied for and was granted an exemption from the NSW Clean Air regulation, allowing Liddell to emit NOx at a concentration of 1400 micrograms per cubic metre (mg/m3).

Power stations of Liddell’s age would normally be subject to the Group 5 NOx limit of 800 mg/m3.

Liddell NOx Comparison

“This is shocking revelation confirms the NSW Government’s laissez faire approach to air pollution control,” Dr Whelan said.

“Liddell is licenced to emit toxic pollution at levels that should see it subject to serious enforcement actions.”

The report, prepared by Aurecon for AGL Macquarie, describes a range of air pollution control measures that would reduce NOx emissions by up to 85%. The report was required by the NSW Environment Protection Agency as a condition of AGL’s Environment Protection Licence.

The Aurecon report identifies Selective Catalytic Reduction (SCR) as the most effective NOx emission control technology and the dominant method in use internationally. Power plants equipped with SCR, overfire air and low NOx burners reduce NOx emissions to just 50-100mg/m3. Japan plans to require new power stations to fit these three control measures.

“Toxic NOx emissions from Liddell could be reduced by more than 90%, significantly improving community health in the Hunter Valley, but generators appear unwilling to invest in these emission controls, especially for older power plants.”

Exposure to oxides of nitrogen (NOx) irritates eyes, nose, throat and lungs, and leads to coughing, shortness of breath, tiredness and nausea. Even low levels of exposure are linked to asthma, reduced lung function and allergies. Coal-fired power stations produce 49% of Australia’s NOx emissions.

Background

  • AGL Macquarie was required by the NSW EPA to submit by July 2017 a report on ‘International best practice for control of NOx emissions from coal fired combustion’. The EPA request for this Pollution Reduction Program (PRP) is a standard procedure for holders of Environmental Protection Licences.
  • EJA has an interest in the PRP because our Toxic and Terminal report identified readily available pollution control technologies (selective catalytic reduction or ‘wet scrubbers’) that would reduce NOx emissions by as much as 90%. (See for e.g. this USEPA report for details.) This equipment has been obligatory for coal-fired power stations in the US for almost 20 years but is not yet required in NSW. The EPA’s licensing philosophy is officially that it requires plants to operate pollution controls that were ‘reasonably available technology’ when the plants were new (23–38 years ago).
  • Although Liddell is scheduled to close in 2022, AGL is experiencing political pressure (most recently from Premier Berejiklian and PM Turnbull) to keep it open beyond that date.
  • NOx concentrations in the Hunter Valley exceed the national standard each year, with major adverse health impacts that have not been assessed by the NSW Government and are clearly not being controlled.
  • Any measures used by Liddell could (and should) be implemented at Bayswater, Eraring, Vales Point and Mt Piper.
  • The (draft) air pollution strategy for NSW indicated that NOx and SO2 emission controls would be investigated. That strategy has bogged down within the EPA, with no sign of life since May 2017.
  • The NOx control report was prepared for AGL by Aurecon (submitted to the EPA in June 2017).
  • EJA requested this report from the NSW EPA late 2017. When that request was unsuccessful, EJA lodged a GIPA (FoI) request in December.
  • In January 2018, the EPA granted partial access to our request, with significant exemptions that included financial figures relating to the purchase of NOx control equipment, operating and capital costs. This redacted information is crucial to any independent assessment of AGL’s efforts to control NOx emissions.
  • A third party – presumably AGL – opposed our request. The third party argued that the report contains ‘commercially sensitive information’, including NOx emissions during combustion, control measures and systems and options for NOx control.
  • The EPA ruled that release of the report was in the public interest.

According to The Guardian, JBS, Cargill and Tyson—three of the world’s largest meat producers—emitted more greenhouse gas last year than all of France and nearly as much as the biggest oil companies, such as Exxon, BP, and Shell.

Hardly any meat or dairy companies publish their climate emissions, so it’s almost impossible to know the exact amount of greenhouse gas generated. But using the most comprehensive data from the Food and Agriculture Organisation of the United Nations, The Guardian estimated emissions from animal agriculture, and the results are staggering.

The top 20 meat and dairy companies emitted more greenhouse gas in 2016 than all of Germany, Europe’s biggest climate polluter. This means if these companies were a country, they would be the world’s seventh-largest greenhouse gas emitter.

It’s impossible to take world leaders seriously when they fail to mention animal agriculture in addressing climate action. Raising animals for food emits more greenhouse gas than all the cars, planes, and other forms of transportation combined.

What’s more, according to the Food and Agriculture Organisation of the United Nations, carbon dioxide emissions from raising farmed animals make up about 15 percent of global human-induced emissions, with beef and milk production as the leading culprits.

But simply by avoiding animal products, you cut your carbon footprint in half. Keep in mind that a pound of beef requires 13 percent more fossil fuel and 15 times more water to produce than a pound of soy. Additionally, a recent study found that switching to a plant-based diet reduces your personal carbon emissions more than replacing your gasoline-powered car with a hybrid.

There is no such thing as “sustainable” meat, and plant-based alternatives to meat, dairy, and eggs take a mere fraction of the resources to produce as their animal-based counterparts.

A vegan diet is not just good for the planet. It also spares countless animals lives of misery at factory farms. Pigs, cows, chickens, and other farmed animals suffer horribly. These innocent animals face unthinkable horrors: cruel caged confinement; brutal mutilations; and bloody, merciless deaths.
