The Federal Government has given NSW Premier Barry O'Farrell a week to respond to new national protections on coal seam gas (CSG) exploration in urban and regional areas.

Federal Environment Minister Tony Burke has repeatedly expressed frustration at NSW demands for a different set of rules on CSG mining.

"We have said we'll fund the independent scientific work so it's being done independently, it's not being done by the companies," Mr Burke told ABC radio.

"And for other states, Queensland, Victoria, South Australia, they've agreed to fully incorporate that information into their process.

"NSW hasn't, I don't know why they haven't."

Mr Burke has asked the premier to write back within a week stating his government's intention on the matter, the ABC reports.

Mr Burke has said the federal government is exploring "all the options" to resolve the dispute with NSW.

Comment is being sought from the NSW government.
