Montana Rivers v. Montana Dep't of Environmental Quality
Annotate this Case
The Supreme Court affirmed the order of the district court granting summary judgment to the Department of Environmental Quality (DEQ) and dismissing a complaint alleging that DEQ violated the Montana Environmental Policy Act (MEPA), holding that DEQ was entitled to summary judgment as a matter of law.
Montana Rivers, the Gallatin Wildlife Association, and Cottonwood Environmental Law Center (collectively, Plaintiffs) brought this lawsuit alleging that DEQ violated MEPA by failing to supplement a 2007 environmental impact statement (EIS) that DEQ had prepared for a proposed rulemaking by the Board of Environmental Review (Board). In 2013, the Board declined to proceed with that rulemaking by ending its notice and comment period and letting the process expire. The district court ruled that Plaintiffs had no viable MEPA cause of action because there was no longer any contemplated state action for which to supplement the EIS. The Supreme Court affirmed, holding that the district court did not err in concluding that there was no proposed state action pending that would obligate DEQ to prepare or supplement a MEPA analysis.
