COLUMBIA, S.C. (AP) - Governor Mark Sanford says South Carolinians should be conservative in their gas usage for the next two weeks while work is being done to return the flow to two major fuel pipelines damaged by Hurricane Katrina.

The pipelines that bring fuel to several Southeast states have been shut down in the aftermath of the hurricane that hit the Gulf Coast early Monday morning.

Sanford says the larger pipeline should be running at 30 percent capacity this week and should be at full capacity within two weeks.

The state also has asked for federal waivers of regulations involving how long fuel tank drivers can be on the road and how much trucks can weigh to help get more gas into South Carolina.
