The State Government has finalised the terms of reference for a major dredging program in the Gladstone Harbour in central Queensland.
The Gladstone Ports Corporation wants to create a nine-kilometre-long shipping lane that is 16.1-metres deep.
The State Government has released the final terms of reference for the environmental impact statement.
It wants to know the possible impacts on marine life as well as the disposal methods for dredge spoil.
State Development Minister Jeff Seeney says there is little change to the draft terms.
"Hasn't markedly changed but it's given people an opportunity to have an input into the process," he said.
Capricorn Conservation Council spokesman Michael McCabe says that is disappointing.
"It's very frustrating for the community to have a lot of effort put into commenting on a draft terms of reference to see little variation," he said.
The Federal Government is yet to hand down its assessment of the $400 million project.
