SIOUX FALLS, S.D. -

Last September, a protest against the Dakota Access Pipeline was held here in Sioux Falls.

Those behind it are organizing another event this Tuesday.

Members of Augie Green, Dakota Rural Action, South Dakotans against Racism and members of the public will be gathering on the corner of 33rd and Summit around 4:45 Tuesday.

From there, they'll walk toward Minnesota Ave., head north and end up back on Augustana University campus.

Organizers are putting on another peaceful protest to show their support for the Standing Rock Sioux Tribe and those fighting on the front line.

They say, as long as they're fighting, people here in the Sioux Empire will be supporting them.

“This is a national thing,” says Tony Helland with Dakota Rural Action. “This is not just an issue for North Dakota or the Standing Rock Sioux Tribe. This is a pipeline that will affect everyone down river on the Missouri, which includes South Dakota, Iowa, Nebraska, pretty much the entire nation."

Dakota Rural Action, and those fighting against the pipeline are worried that the pipeline will leak, and thus pollute area drinking water.
