Provide more info on groundwater management plans: Queensland govt tells Adani

Australia's Queensland state government has asked Indian energy giant Adani to provide more information on its groundwater management plans, posing another hurdle which may further delay the construction of its proposed billion dollar mine project, expected to be one of the biggest in the world.

The decision came after the Queensland government rejected a management plan of Adani to protect endangered black-throated finch bird population, saying the company's proposals do not meet the approval conditions.

The black-throated finch management plan and a groundwater plan are the two persisting hurdles before the Indian energy giant could begin work on its controversy-hit Carmichael mining project in Central Queensland.

Adani Mining's chief executive Lucas Dow said the new request came from the Department of Environment and Science (DES) last Friday, Australian Associated Press news reported on Monday.
