Friday's accident prompted the evacuation of about a half-dozen homes and the closing of Texas 6 in southern Brazos County for about seven hours.

Brian Dunphy, public affairs adviser for Exxon Mobil, said Sunday a temporary clamp was placed on the pipeline and it was back in service. A permanent repair will be made soon.

Remediation work also had begun. Dunphy said temporary dams on a nearby creek helped contain the gasoline although some became mixed with water in the creek. That gasoline was being cleaned up Sunday.

Dunphy said once that work was completed, soil affected by the leak would be excavated.

Authorities weren't sure how much gasoline spilled from the pipeline before it was capped Friday night.

"What made it so dangerous was the amount of product in the air -- the risk was that those vapors could ignite," Chuck Frazier, emergency management coordinator for Brazos County, said in a story in the Bryan-College Station Eagle. "But everyone -- from the firefighters and law enforcement to the company officials -- everyone did their jobs well and there were no major problems."

State officials closed a three-mile stretch of Texas 6 because of fears that a motorist might throw a cigarette out the window and ignite the fumes. Crews from Exxon Mobil poured foam on the gasoline to suppress the vapors.

The rupture occurred when an independent contractor hit the line while using a "scraper" to gather dirt a few hundred yards from the construction site.
