The U.S. Environmental Protection Agency gave final approval this week to list a stretch of the Gallatin River as impaired, prompting Montana to continue studying the river’s pollution sources and come up with a cleanup plan.

The determination comes over a year after five groups petitioned the Montana Department of Environmental Quality to consider the Gallatin River as impaired by toxic algal blooms.

Last June, the DEQ issued a draft decision that the river was impaired, but the state needed federal approval of the decision to finalize the river’s status under the Clean Water Act.
