Public Meeting about the MT DEQ Gallatin Impairment Proposal

Public Meeting about the MT DEQ Gallatin Impairment Proposal

The Montana Department of Environmental Quality (DEQ) is proposing to list the middle segment of the Gallatin River, from Yellowstone National Park to Spanish Creek, as impaired for excessive algal growth due to exceeding established thresholds for algae (ARM 17.30.637(1)(e)). The listing has been submitted to the U.S. Environmental Protection Agency for review and, if approved, will be included as an addendum to the 2020 Integrated Report—a report that identifies impaired waterbodies in Montana.

DEQ’s Water Quality Planning Bureau will host an informational public meeting covering topics related to the proposed listing. The hybrid meeting will be held in Big Sky and online.

Meeting Agenda:

  • Nutrient Rulemaking Update
  • Gallatin River Listing Update
  • Gallatin River Monitoring Project Objectives & Timeline
  • 2023 Monitoring Strategies
  • Source Assessment and TMDL Development
  • Opportunities for Community Involvement
