TransCanada not ready to forecast Keystone restart

* TransCanada says no firm timeline for restart

* Previously said restart in a few days

* Spill clean-up wrapping up

BENDENA, Kansas (Reuters) – TransCanada Corp said Thursday it still does not know when it will reopen the 591,000 barrel per day Keystone pipeline after shutting in on Sunday following a small oil spill.

The company said the line will reopen in “the coming days” but declined to be more specific.”

“We continue to move forward with plans to restart Keystone in the coming days but we don’t have a specific date determined yet,” Terry Cunha, a spokesman for the company, said in an email.

The line was pumping about 480,000 bpd of crude before a half-inch fitting failed at the Severance pumping station, leaking about 10 barrels (420 gallons) of oil.

Keystone, which runs from Hardisty, Alberta, to Cushing, Oklahoma, is a key feed for the Cushing oil storage hub, the pricing point for the New York Mercantile Exchange’s benchmark crude contract.

The shutdown helped push U.S. crude futures up by as much as $3 a barrel earlier in the week.

Most of the spill was kept within containment dams set up at the pumping station, but some oil escaped as mist. Workers cut back prairie grass, replaced fences and wiped down equipment that had been sprayed.

The company said it expects clean-up work to be completed Thursday while repairs to equipment at the site will take a few more days.

A problem with a larger fitting was blamed for a 500-barrel leak earlier this month at another Keystone pumping station in North Dakota. That shut the line for six days while the company replaced similar fittings at other pumping stations.
