A group of anti-pipeline protesters say they are disrupting an Enbridge work site west of Highway 8 in Flamborough in an effort to stop work on the company's Line 10 expansion project in the area.

The group says it began blocking worker access out of their morning staging site this morning so employees can't get to Enbridge work sites.

In a media release, organizer Jaydene Lavallie said that the company's pipelines are prone to spills.

"Even when they aren't spilling, the production of tar sands oil poisons millions of gallons of clean water an hour past any potential remediation."

Work on Line 10 has attracted its share of opposition.

Enbridge construction crews are in the midst of decommissioning a 12-inch pipeline from Westover to the Nanticoke Junction Facility in Glanbrook and replacing it with a 20-inch one. But the plan has attracted opposition, particularly in light of news that it would involve felling thousands of trees.

In a statement Enbridge spokesperson Jesse Semko told CBC News that Enbridge respects the group's right to "peacefully protest.

"On the morning of Wednesday, December 13, approximately 30 people showed up to protest at a construction yard off Highway 5 in Flamborough, Ontario. We respect the right of people to protest but expect that all activity remains lawful and peaceful," he said. "We are working with police and want a peaceful resolution to the situation."

Hamilton police say they are on scene at the work site and anticipate being there for "some time."

Const. Jerome Stewart said that there are some traffic issues in the area being affected by the protest blockade. He says a worker's vehicle became stuck in a ditch when it was trying to get off the property.

"There should be one cruiser there for the better part of the day unless things miraculously clear up," he said.

No arrests have been made.
