Chevron Gorgon Project expansion to use HDD

Approved 3 March 2015, the project – known as the Gorgon Gas Development Fourth Train Expansion Proposal – will seek to expand the liquefied natural gas (LNG) production capacity on Barrow Island, Western Australia by 33 per cent, from 15 to 20 million tonnes per annum. According to Environmental Protection Authority (EPA) Chairman Dr Paul Vogel, the proposal’s horizontal directional drilling (HDD) component had been subjected to a Public Environmental Review, the Authority’s highest level of environmental impact assessment. “The EPA carefully assessed the potential impacts to marine environmental quality, marine fauna, air quality and benthic communities and habitat and found that the proposal could be managed to meet the EPA’s objectives subject to the conditions in the existing Ministerial Statements issued for the original project.” These conditions included management plans for the HDD activities, alongside marine environmental quality, gas pipeline installation, marine fauna, air quality and greenhouse gas abatement, said Dr Vogel. The EPA’s report to the Minister for Environment is now open for a two-week public appeal period, closing 17 March 2015. Appeals are administered independently by the Appeals Convenor and can be made here. The Minister for Environment will make the final decision on the project’s approval.
