Northern Cheyenne Utilities Commission — Wastewater Treatment Violations, Montana (2023)

Outcome: Northern Cheyenne Utilities Commission agreed to make significant physical and operational improvements to its wastewater treatment facility and pay a $1,500 civil penalty — reduced from the calculated amount based on documented inability to pay — resolving Clean Water Act violations at the facility serving the Northern Cheyenne Indian Reservation in Lame Deer, Montana.

The Northern Cheyenne Utilities Commission (NCUC) provides water and wastewater services to the Northern Cheyenne Indian Reservation in Lame Deer, Montana, a rural tribal community in southeastern Montana. The utilities commission's wastewater treatment facility failed to meet Clean Water Act NPDES permit requirements, resulting in violations of the permit's effluent standards and treatment requirements. As a tribally operated utility serving a reservation community, NCUC operates under direct EPA jurisdiction without state primacy intermediary.

The settlement, announced August 2023, required the NCUC to implement significant physical and operational improvements to the wastewater treatment facility to achieve and maintain NPDES permit compliance. The civil penalty was set at $1,500 — far below the calculated penalty amount — based on EPA's application of the inability-to-pay doctrine after the commission demonstrated that full penalty assessment would prevent the funding of required compliance improvements or cause financial hardship to the tribal community served.

The case reflects the environmental justice dimensions of tribal utility enforcement, where EPA must balance its compliance enforcement mandate with recognition that tribal communities on rural reservations often lack the tax base and grant funding access to maintain wastewater infrastructure at the standard expected of larger municipal utilities. EPA's inability-to-pay determination process, when properly documented, allows enforcement actions to result in actual compliance improvements rather than simply imposing financial penalties that prevent remediation investment.
