The project could transform the nation’s energy exports but has raised the ire of environmentalists.

More than three years and 100,000 hours of studies since first proposed, the project’s final filing was posted on the website of the Canadian Environmental Assessment Agency on Monday, according to a Bloomberg report.

Canada’s Natural Resources Minister Jim Carr committed in June to decide whether to approve the project within 90 days of final submission.

Reuters reported that Petronas and its partners have been waiting about three years for a permit to build the Pacific NorthWest LNG export terminal in northern British Columbia.

State-owned Petronas’s partners in the project include China Petroleum & Chemical Corp, Japan Petroleum Exploration Co, Indian Oil Corp and Brunei National Petroleum Co.

The review process was last paused in March when the regulator requested more information from the company.

The Bloomberg report said the USD28 billion project aims to ship gas from Lelu Island – a small, uninhabited islet on the Pacific Coast – to energy-hungry Asian markets.

Yet its approval has been mired over concerns about the impact on fish, wildlife and the traditional ways of life of First Nation tribes in the region.
