Nutrient Standards Lunch & Learn

In the 2025 Legislative Session, House Bill 664 repealed numeric nutrient criteria found in Circular DEQ-12A. In October of 2025, EPA approved the water quality standard change, making it effective for all DEQ programs.

Join the Montana Watershed Coordination Council and the Gallatin Water Collaborative for a virtual Lunch and Learn session at noon on February 10th to learn about DEQ’s implementation of the narrative standard for nutrients, including what has changed, what has not, and what is next. Time will be reserved for Q&A. Please RSVP HERE.
