The Montana Department of Natural Resources and Conservation (DNRC) Conservation and Resource Development Division (CARDD) is issuing a Draft Environmental Assessment for the City of Missoula/Missoula County Grant Creek Realignment Project. The project proposes to use American Rescue Plan Act (ARPA) funds to provide three miles of new collector and minor arterials of roads, new sewer and water mains, 3.7 miles of new trails, and 0.5 miles of stream restoration and flood control.

Applicant is requesting an Alternative Practice to operate equipment, as well as deposit slash within the Streamside Management Zone (SMZ) of Pierce Creek, a Class 1 stream.

To analyze impacts associated with the proposal to allow the operation of tracked equipment (excavator) in a streamside management zone allowing the full suspension and removal of windthrown trees from the SMZ including those across the stream channel. The proposed action would allow logging equipment to salvage approximately 10 trees scattered along 750 lineal feet of Class 3 SMZ.

Hiland Cude LLC, referred to as the Proponent, is applying for a 25’ Right of Way Easement (1.44 acres). Kinder Morgan is gathering the crude off the Kraken- Northern Pad that is located approximately 1 mile Northwest of this State Land tract. Kinder Morgan is proposing to install up to a 4-inch steel crude pipeline through State Land to gather the crude and transport it through the proposed pipeline to their existing pipeline facilities.

On June 8, 2026, DNRC received an application from the Proponent, AWSW LLC dba Hamlin Water, for the placement and operation of a temporary layflat hose for the purpose of transferring freshwater across Montana trust lands. The water would be utilized for the fracturing of a horizontal Bakken well(s). This analysis does not evaluate the impacts or usage of the water nor the fracturing of the horizontal Bakken formation well itself. The analysis evaluates the impacts of the placement, removal and operation of a hose. The Proponent has applied for an effective duration date of June 15, 2026, through October 15, 2026. The hose would be expected to be placed near the beginning of the duration and removed near the end of the duration.

This action would authorize the drilling of boreholes for geotechnical investigation for the future installation of a water pipeline for drinking water on Montana State Trust Lands, including all associated construction, maintenance, and use activities. This water pipeline will utilize water from the Madison Aquifer to small communities and rural families in central Montana.

This proposal includes timber harvest on roughly 95 acres. Timber harvest treatment would include shelterwood and seed tree prescriptions in a Douglas-fir stands that are susceptible to insect, disease, and high-severity wildfire. Approximately 400 thousand board feet would be harvested. Slash piles will be burned during the winter months when conditions are safe. Maintenance will take place on 0.60 miles of existing road. Roughly 0.40 miles of road may be constructed to facilitate logging operations away from a nearby Streamside Management Zone. Noxious weed monitoring and subsequent herbicide application may occur as necessary.

WBI Energy Transmission, Inc. (WBI Energy) is proposing to relocate an exposed section of natural gas pipeline by guided bore method under the Milk River in Valley County, MT. Approximately 1,520 feet of 8-inchdiameter natural gas pipeline is proposed to be bored beneath the Milk River. The proposed 1,520-foot pipeline will cross both tribal trust land within the Fort Peck Indian Reservation and State Trust lands managed by the DNRC. DNRC owns approximately half of the stream bed and must decide whether to either allow the entire project, allow a temporary mitigation project, or not allow the project to proceed on State Trust Lands. Here we review the environmental risk associated with these alternatives with an EA that is tiered to the BIA Final Environmental Assessment for the Saco-Morgan Creek Milk River Bore Project (Attachment A – BIA EA). The BIA EA reviews and addresses a broad scope of issues. DNRC Trust Lands staff reviewed the BIA EA and found the analysis adequate. Therefore, this analysis tiers to the BIA EA and focuses instead on a more narrow scope of issues to be considered by DNRC Trust Lands as the landowner who will decide to approve no project, a temporary mitigation, or the entire project.
