UPDATE 5-Outages, floods hit 2 New Jersey refineries; others restart

* Phillips 66's 238,000-bpd plant has flooding, power out

* Philadelphia's 330,000-bpd refinery restarting

* Hess 70,000-bpd NJ refinery, Imperial plant suffer outages

* Gulf Coast's Colonial Pipeline without power at NJ pump

* Gasoline futures pare losses as power glitches surface

NEW YORK, Oct 30 (Reuters) - The second-largest refinery on the U.S. East Coast has suffered ``some'' flooding and a power outage from Hurricane Sandy, while two smaller plants also lost power, as glitches threaten to slow the recovery in fuel supplies.

While the region's biggest plant, in Philadelphia, and several others were ramping up operations after escaping damage, other facilities, pipelines and terminals were struggling to restore supplies that had slowed to a trickle.

Phillips 66 said there was ``some flooding in low-lying areas'' of its 238,000-barrels-per-day Bayway, New Jersey plant, which had been shut on Monday as a precaution. The plant remains closed, the company said, and utility PSE&G said power was likely to be restored only in 24 to 48 hours.

News of trouble at Bayway, nicknamed the ``gasoline machine'' for its key role in supplying motor fuel to the New York City area, pared losses in gasoline futures, which had fallen by more than 2 percent as output recovered elsewhere.

Other power-related glitches also surfaced after the storm, which left more than 8 million customers without electricity.

As the storm moved north, a power outage shut Imperial Oil's 121,000-bpd Sarnia, Ontario refinery, but the company said it expected to restart units later in the day.

Hess Corp's 70,000-bpd Port Reading, New Jersey refinery, which had also shut ahead of Sandy, lost power and had no time frame for restarting.

Colonial Pipeline, a conduit that supplies as much as 15 percent of the East Coast's 5.2 million bpd of gasoline, diesel and fuel demand from Gulf Coast refiners, said the line had suffered no operational damage, but it had lost power at its Linden, New Jersey tank farm. It is bringing in portable generators to resume pumping fuel back to the region.
