Chevron’s Gorgon development fourth train expansion proposal, which is expected to expand the LNG production capacity on Barrow Island from 15 to 20 mtpa, has been recommended for conditional approval by the Environmental Protection Authority.
The fourth train expansion proposal would involve drilling new production wells and installing new subsea infrastructure in Commonwealth waters, construction of a new feed gas pipeline system, and the addition of a fourth LNG train and associated infrastructure within the company’s existing gas treatment plant on Barrow Island.
Existing infrastructure constructed as part of the original project will be used to export products generated by the fourth train expansion proposal, EPA said.
EPA Chairman Paul Vogel said the fourth train expansion proposal had been rigorously assessed at the Authority’s highest level of environmental impact assessment, a Public Environmental Review (PER).
“Horizontal directional drilling, offshore gas pipeline installation activities and fourth train operation have the potential to impact on the environment,” Vogel said.
He added that 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 include management plans for marine environmental quality, HDD activities, gas pipeline installation, marine fauna, air quality and greenhouse gas abatement.
