More calls for ethane power inquiry Keith Platt keith@mpnews.com.au THE Save Westernport community group has joined calls for a full investigation of the likely environmental effects caused by an ethane gas fired power station at Hastings. The group, which was instrumental in preventing AGL’s floating gas import terminal being anchored at Crib Point, says essential details are missing from Esso’s plans to generate power at Long Island Point. It says the need for Esso to find a use for its excess gas raises questions about the viability of the Esso plant and, faced with declining gas resources in Bass Strait, suggests it should be “considering decommissioning its operations at Long Island Point”. “Esso is urgently trying to get this project approved because they have lost their customer for ethane, which is the major byproduct of gas processing at Long Island point.” “An EES (environmental effects statement) would allow the claims made by Esso in their project application to be independently assessed,” Julia Stockigt, of Save Westernport said. Mornington Peninsula Shire, although having no planning powers over Esso’s proposal, has also called on the state government to investigate possible health risks and environmental impacts of using ethane to generate electricity (“Shire’s ‘no’ to Esso’s bid for power” The News 28/6/22). Esso says it can use the ethane, a by-product from natural gas used at

Shire officers, who admitted they did not have enough time to thoroughly assess the proposal, said its “climate change impacts are acceptable”, adding six per cent a year to the peninsula’s greenhouse gas emissions. Councillors ignored the officers’ recommendation to approve Esso’s plan and instead called on Planning Minister Richard Wynne to fully investigate its health and environmental effects. Save Westernport said an EES would “allow the claims made by Esso in their project application to be independently assessed”. It says that over past decades “toxic plumes” from Esso’s plant at Hastings had become “an increasing cause of local concern”.

The company now wanted to build three electricity generators as a result of the need to find an alternative use for its ethane. “Esso has devised a plan to generate electricity using ethane as fuel - apparently this practice is extremely uncommon, with remarkably few examples operating anywhere in the world. Esso’s proposal involves many unknowns,” Save Westernport states. “Among countless unanswered questions about the project’s many impacts is the unanswered question of how much emissions it will produce. All the information in Esso’s supporting documents concerns methane in electricity generation, however Esso proposes using ethane in its electricity generators. “Ethane in power generation is so obscure, a recent article on the 25

uses of ethane, does not even mention ethane in the generation of electricity. However, it does describe its use in the production of mustard gas. “Of particular concern were Esso’s claims that this highly experimental project would not trigger any governmental safety considerations or environmental assessments.” In outlining the possible dangers of the power generators, the group draws on a 2021 statement by Wynne when rejecting the AGL gas import proposal: “It’s very clear to me that this project would cause unacceptable impacts on the Western Port environment and the Ramsar wetlands – it’s important that these areas are protected.” Save Westernport said residents “know little or nothing about the project that would impact their lives and compromise their health and the local amenity for many years to come, unless Esso’s application is refused”. The group said Esso had not explained how it could limit the need to flare excess gas and questioned the its assessment of noise levels, accusing it of ignoring French Island residents. “The impacts on Western Port’s migratory shorebirds and other fauna have not been properly considered, though several species would be significantly impacted by industrial noise, dust, increased traffic, and skyglow resulting from the project. “Skyglow, caused by high level industrial lighting, has become a major disruptor of migratory bird flights. It is one of a number of impacts that will need to be assessed.”

Deer ‘strategy’ puts them in shooters’ sights THE Department of Environment, Land, Water and Planning has confirmed that feral deer will be shot at Devilbend Natural Features Reserve, Tuerong. The department did not reveal when the shooting would begin or how many deer were estimated to be in the reserve. Chief biosecurity officer James Todd said while there not had been a formal survey, the number of reported sightings of deer “suggests there has been an increase in deer numbers on the peninsula”. The primary control method for the deer is shooting, which will be carried out by professional shooters, accredited volunteer hunters, commercial harvesters and recreational hunters (“Shooting deer a ‘control’ option” The News 19/7/22). The state government has provided $19.2 million over four years and $4.4 million a year ongoing for the development and implementation of regional deer control plans under the Victorian Deer Control Strategy. DELWP says the strategy provides a clear and coordinated approach to controlling deer in Victoria. The strategy recognises the increasing and significant impacts of deer on biodiversity and the broader environment, Aboriginal cultural heritage, agriculture, public safety, and community expectations.
