UPDATE 2-Enbridge Line 14 pipeline expected to restart Wed-official

* Repairs on pipeline expected to be completed on Tuesday

* Pipeline could be refilled with oil by Weds-official

* Line carries Canadian crude to Chicago-area refineries

July 31 (Reuters) - Enbridge Inc could get approval from U.S. regulators to restart the Line 14 crude oil pipeline by Wednesday evening after a spill in Wisconsin forced its closure, a local official said.

The 318,000-barrels-per-day Line 14, which carries Canadian crude to refiners in the Midwest, was shut on Friday after the discovery of the spill that leaked more than 1,000 barrels of crude, covering one nearby house with oil.

Line repairs were expected to be completed on Tuesday, prior to testing by the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA), Ed Culhane, spokesman for the Wisconsin Department of Natural Resources, said.

"They expect to have the line running again by the evening of August 1 at the latest," Culhane said.

"I wouldn't be surprised if the line is repaired already, then they need to X-ray the welds before filling it with water at a higher pressure than the crude normally runs to test it."

Culhane said if the line passes the test, it could be refilled with crude by Wednesday night.
