The Montana Department of Environmental Quality (DEQ) is proposing to issue renewed authorization under the 2023 Concentrated Animal Feeding Operation (CAFO) General Permit (GP) for a large CAFO ISO wean barn, dairy barn, beef feedlot, and small poultry barn to Big Stone Colony.

The MPDES CAFO General Permit MTG010000 regulates the manure, litter, and process wastewater generated by CAFOs to ensure that CAFO activities do not harm water quality.  

The facility’s NOI-NMP package is being made available for a 30-day public review and comment period. During the public comment period, any interested person may submit written comments and may request a public hearing. A request for a public hearing must be in writing and must state the nature of the issues proposed to be raised in the hearing. DEQ will respond to any significant comments received during the comment period, and if necessary, require the CAFO owner or operator to review the NMP.
