"Following this independent assessment and the Department of Environment and Energy's recommendation for approval, I have accepted the scientific advice and therefore approved the groundwater management plans for the Carmichael coal mine and rail infrastructure project under the Environmental Protection and Biodiversity Conservation Act 1999", she said.
This decision does not comprise the final approval for this project, Price said in her statement.
She says CSIRO and Geoscience Australia believe the Indian company's revised plans for the way it manages groundwater resources meet scientific requirements.
Bill Shorten - who, like the government, has been caught between the conflicting imperatives of campaigning in central Queensland and in southern Australia on this issue - said the Queensland government now had to go through its processes.
He said the Queensland government was yet to sign off on Adani's Black-Throated Finch Management Plan and Groundwater Dependent Ecosystem Management Plan.
Price insisted the approval was made on scientific grounds with input from the CSIRO and Geoscience Australia.
However, Price reiterated it will ultimately be up to the Queensland pollies to greenlight nine remaining environmental plans.More news: Sights from the Masters: Wednesday at Augusta National

Ms Landry stressed the decision does not mean everything is now signed off and said it was now back to the State Government (see above).
It will tell residents it wants the Queensland government to get the project up and going so it can deliver thousands of jobs. "We are not interested in sovereign risk".
With a green light from the Queensland Government, construction can now begin on the mine north of the Galilee Basin.
Her department will take the time it needs to properly consider the plans, which she says must be in tune with the state's environmental laws.
One Nation has long supported the Adani coal mining project while maintaining its preference for the heavy haulage railway line to be built and owned by the federal government.
Price has been reportedly under pressure from Queensland Members of Parliament to approve the plan before Prime Minister Scott Morrison calls a general election and the parliament enters caretaker mode, at which point the incumbent Liberal-National Party coalition (LNP) would have to consult with the opposition Australian Labor Party (ALP) before granting the approval.
