Keystone XL Pipeline critics gathered on the steps of the Civic Center in downtown Great Falls on Wednesday to protest and speak out against the pipeline's construction.
Livestock owners, Fort Peck Tribal Members, and representatives from the Northern Plains Resource Council spoke about the local impacts the project could have.
The groups said the pipeline may cause environmental problems for drinking water and irrigation systems.
Protesters from around the state including Glendive and Bozeman rallied against the project.
Shannon Wilson, a retired environmental engineer, said she's concerned about potential accidents in the pipeline and the environmental impacts.
"One lady from Fort Peck traveled here, started out at 5:30 this morning, so y'know I'm here to support them too because it's going through their land," Wilson said.
According to Senator Steve Daines, the project could bring in revenue for Montana's rural communities.
He said the pipeline is a much-needed economic driver for those areas and the project will create hundreds of good-paying jobs for Montanans.
