NEB keeping close eye on pipeline firm Plains Midstream

Canada's energy regulator said TuesdaythatPlains Midstream is co-operating in addressing pipelinesafety and other concerns.

In January, the National Energy Board (NEB) ordered thepipeline company with a recent history of large spills to do an independent audit of its entire network.

• Plains Midstream fined $1.3M after guilty plea
• Plains Midstream criticized for pipeline leak into Red Deer River

The NEB said back then thatit hadserious concernsabout the company'shazard identification, risk assessment, risk control, training and documentation of safety procedures. Today, NEB officialssaid it's still too early to declarethatPlains Midstreamis out of the woods.

"That still remains to be seen. The board's concerns were pretty valid aboutensuring the safety of their pipeline system," saidTim Sullivan, the NEB'slead auditor for environment."We have had quite a number of conversations with Plains about the steps they have taken to date. The board is still reviewing all of that information. We will make some decisions later on."

The Calgary-based company will have to undergo an independent audit later this year. The company made its April 30deadline to submita quality assurance program. Company officials havealso metregularlywith NEB staff to update their progress.

"There was a first condition with updating some of their safety procedures. They filed that information with the board. We're still reviewing that information to determine whether it is compliant or not," said Sullivan.

Last summer, the company paid $1.3 million in fines for two spills that sent nearly five million litres of oil into Alberta rivers and wetlands.

An agreed statement of facts said a poorly welded and highlystressed section of the nearly50-year-old Rainbow pipeline cracked on April 28, 2011. About 4.5 million litres of oil spilled near the northern Alberta community of Little Buffalo.

In June 2012, the company also pleaded guilty to a spill into the Red Deer River near the community of Sundre in central Alberta after alength of the 48-year-old Rangeland pipeline underneath the river failed.

Homes were evacuated, several Sundre residents were sent tohospital, drinking water was affected,and nearby Gleniffer Lake was closed for three weeks.

"When we have a concern about safety, and we did in the case of Plains Midstream, we want to ensure that the company is doing everything they can and are taking stock of all their systems and process," NEB CEO Peter Watson told CBC News.

The company operates inAlberta, Saskatchewan, Manitoba and Ontario.
