A North Vancouver woman who spent 10 years on the run in a high-profile eco-terrorism case is planning to plead guilty, court documents show.

Rebecca Rubin will change her previous not guilty plea to guilty, on charges connected to one of the biggest eco-terrorism cases in U.S. history.

Rebecca Rubin was indicted in 2006 for a ski resort arson in Vail, Colorado, and other domestic terrorism crimes in the U.S. ((FBI))

Rubin, 39, is accused of being a member of the radical environmental groups the Earth Liberation Front and Animal Liberation Front, known to use extreme measures.

The charges against Rubin are related to the firebombing of wild horse corrals in Oregon and California and setting fire to a ski resort in Colorado between 1996 and 2001.

No one was killed in the fires, but they caused an estimated $40 million in damage.

At the time, the FBI characterized the group as the top domestic terrorism threat in the country. In 2008, the FBI offered a $50,000 reward for tips leading to Rubin's capture.

Rubin is believed to have spent time in B.C., and last November she surrendered to the FBI at a B.C.-Washington state border crossing.

Rubin, who is charged with conspiracy and arson, will be in U.S. District Court in Portland to enter a guilty plea, the court documents show.

Each count of arson and attempted arson carries a mandatory minimum sentence of five years in prison, up to a maximum of 20 years. Conspiracy carries a maximum sentence of five years.
