The Carmichael Mine in project received environmental approval from the state of Queensland, with about 140 conditions.
Adani is working to build the mine, one of the world’s largest coal mines, located near the fragile Great Barrier Reef and has been saddled with controversy for the $16.5 billion project ABC News Australia reported.
The department said the conditions include nine provisions relating to the black-throated finch, an endangered species, as required by a court.
“The [Department of Environment and Heritage Protection] is confident the strict conditions ... will ensure this mine will not pose an unacceptable risk to the environment and any potential impacts will be closely monitored,” it said in a statement.
Adani has now gained environmental approval from the state and federal governments but needs to prove its finances and gain a mining license from the state for the site.
The $16 billion mine, rail and port project has been marred by protracted legal challenges.
Two court cases, from traditional owners and the Australian Conservation Foundation, are still ongoing.
A spokesperson from Adani urged the Queensland Government to prevent any further delay to the granting of the final mining lease.
“While a welcome development, it is now critical that the State Government works actively with us and ensures no further delays can be made to final approvals such as the granting of a mining lease,” it said
“Progress on these approvals is crucial in ensuring the jobs and economic benefits from these projects can flow to regional Queensland at a time these opportunities are sorely needed.”
A spokeswoman for Queensland Mines Minister Anthony Lynham said a number of statutory obligations needed to be addressed before the Minister would consider granting the lease.
The Carmichael mine would be one of the biggest mines in the world, consisting of six open-cut pits and up to five underground mines, and will supply Indian power plants with enough coal to generate electricity for up to 100 million people.
The controversial project involves dredging 1.1 million cubic metres of spoil near the Great Barrier Reef Marine Park, which will then be disposed of on land.
