Residents are being urged to give their views on new targets for mineral extraction in Surrey.
The county council is holding a public consultation until 6 June over new plans to look at land for silica sand and brick clay quarrying.
The authority said it was told in April to look at sites where the minerals could be extracted, in addition to gravel and sand sites agreed in 2005.
The plans may mean the creation of a new quarry and the extension of others.
Silica sand is used in the manufacture of glass.
The authority said it was also being asked by the government to look at the storage of gas and could not say no to the revised targets.
David Harmer, of Surrey County Council, said: "We've had a good response from the people of Surrey giving their views on the plan and I would encourage anyone who has not yet made their point to do so as quickly as possible."
Residents will also be given the chance to comment when the plan is submitted to the government in July 2009, the council said.
