An investigation by the Alice Springs News Online has revealed that the sulfur content in crude oil from Mereenie is very low, just 0.1%, making it potentially suitable for use in diesel engines without refining.
Central Petroleum would not confirm this, saying “under our joint venture agreement we can only provide this information under confidentiality agreement”.
But the information is contained in a report by the Department of Resources and Energy, saying “the sulfur content of oil and condensate alike is low (less than 0.1 per cent)”. (Bureau of Mineral Resources, Geology and Geophysics, Australian Petroleum Accumulations Report 1, Amadeus Basin, Central Australia 1986).
At the current wellhead price of 45c on the field 250km west of Alice Springs, crude could be sold for well under $1 a litre in Alice Springs, including the 30c Federal fuel tax, and transport.
Yet Territory bureaucrats contacted by the News are refusing to act on this information, and the crude is sent on a 15,000 km round trip to Singapore for refining before being sold here as diesel at $1.29.
These are salient the facts:–
• Unrefined Mereenie crude was used by local truckies some 12 years ago.
• The oil field produces an estimated 60% of the demand for diesel in Alice Springs.
• A lower diesel price would not only benefit locals, it would significantly stimulate self-drive tourism.
• It makes no sense to apply one-size-fits-all pollution measures to cities choked with traffic and Central Australia, one of the world’s most sparsely populated regions.
• Until December 2002 the uniform standard was 0.05% of sulfur in diesel (half of what the Mereenie crude contains). In January 2009 it was reduced to 0.001%.
• Central Petroleum, which mines the crude, is happy to sell it to anyone.
• The Commonwealth Environment Minister, currently Greg Hunt, has the power to grant exemptions to rules for the use of fuels, for example, in Central Australia.
• A strong argument could be made for such an exemption if it could be demonstrated that national air quality standards for sulfur dioxide would not be exceeded in Central Australia by limited use of unrefined Mereenie crude.
• We asked the NT public service to calculate, expressed in engine hours, what level of use of unrefined Mereenie crude would exceed the air quality standards (see footnote).
• The request was rejected, and we were barred by a media official from talking to NT public servants directly about these issues.
• A government media official told us that we could quote a departmental spokesman as saying: “Since the department doesn’t have a role in the enforcement process, it refers you back to the Federal Government.”
• The NT Government does have a role in formulating the National Environment and Protection Measure for Ambient Air Quality and that “jurisdictions put strategies in place to reduce emissions and to achieve the standards”.
All the while, the NT Government is trying convince the public that it will have a direct benefit from proposed “gas to liquid” production of fracked gas converted to diesel.
It is clear the Northern Territory Environment Protection Authority (EPA) is dealing with sulfur dioxide emissions – its website shows that – and surely it has staff qualified to assist in making a case to Canberra for the benefit of the public they are meant to be serving.
The EPA website says: “Sulfur dioxide in the atmosphere arises from both natural and human activities. Natural processes which release sulfur compounds include decomposition and combustion of organic matter; spray from the sea; and volcanic eruptions.
“The main human activities producing sulfur dioxide are the smelting of mineral ores containing sulfur and the combustion of fossil fuels.
“Sulfur dioxide dissolves in water to form sulfuric acid. This is a corrosive substance that damages materials and the tissue of plants and animals.
“Sulfur dioxide irritates the airways of the lungs. People with asthma who are physically active outdoors are most likely to experience the health effects of sulfur dioxide. This may include wheezing, chest tightness, and shortness of breath.”
All this, one would imagine, would not occur at unacceptable levels if the mandated limits are not exceeded.
We are inviting comment from Chief Minister Adam Giles, and candidates for Central Australia in the NT Elections on August 27 (including Bess Price, Robyn Lambley, Steve Brown, Dale Wakefield and Scott McConnell) as well as 1Territory and the Greens.
The Sulfur dioxide limits (0.2 parts per million averaged over a one hour period, 0.08 ppm averaged over a 24 hour period, 0.02 ppm averaged over a one year period) would be exceeded in Alice Springs if X cars drove here.
The cars have 6-cylinder, 4000cc diesel engines. They are using unrefined Mereenie crude as their fuel. The sulfur content of Mereenie crude (oil and condensate alike) is no more than 0.1 per cent.
What number is X?
Local $1 diesel? NT bureaucrats couldn't care less.
