Denbury Well MC31-16SH & NH 2019-07-23
Denbury Onshore LLC henceforth referred to as proponent has requested to construct two co-located oil wells, pad site, pipeline and access road on the section of Trust Land mentioned above. This section of land is managed by the Montana Department of Natural Resources Eastern Land Office. This oil well will be in the Cedar Creek Coral Creek Unit. The well depth will be approximately 12,550 feet on the south well and 13,432 feet on the north well, both would be drilled into the Mission Canyon formation. These wells would be placed in common on one pad site, the total area of the pad site for drilling operations would be approximately 4.95 acres. Once drilling is completed the pad size will be reduced to 2.64 acres. Any pits will be constructed on cuts and will not be allowed on fills. Cuts will range from 0-9.9 feet. Fills will range from 0-10.1 feet.

Proposed Oil Well- #1 Vecta State 12-34 2019-07-09
True Oil has requested permission to drill an oil well on State Land. The vertical well will be drilled into the Madison formation at a total depth of 2,600 feet. The proposed wildcat well is located on classified grazing land. A 300’ X 250’ drilling pad will be constructed, and a single rig will drill the well. If sufficient quantities of oil are present, then commercial well sites will be developed. If tests indicate that commercial quantities of recoverable oil are not present, then the well will be plugged and reclaimed in conformance with standards approved by the Montana Board of Oil and Gas Conservation.

Forest Practices

Sun Mountain Lumber AP 2019-07-03
Sun Mountain Lumber (SML) is applying for an Alternative Practice (AP) to operate tracked equipment within the Stream Side Management Zone (SMZ) of a class 1 stream and remove trees in excess of SMZ Law retention standards. This project is located on private land in the Wisconsin Creek area of Section 20, Township 3 South, Range 4 West (see attached map). The project area is a historic hard rock mining town (Leiterville) with numerous structures in various states of disrepair and decay, some still being livable and some no more than a pile of boards. The project would be expected to impact approximately 188 feet of Class 1 Stream Side Management Zone (SMZ) along Wisconsin Creek and remove up to 35 trees ranging in size from 8-inches to 30-inches DBH. The Alternative practice would facilitate the removal of trees posing a safety hazard to 2 historic cabins on the property.

Red Rock Springs Ranch Stock Water Pipeline LUL 2019-07-09
This environmental assessment is being conducted to study effects of a proposed buried stock water pipeline, above ground water storage tank, and a stock tank to be located on the above referenced Trust Land Tracts. The pipeline would originate at an existing spring development on Trust Land located in the SWNWSWSE, Section 21, T11S R9W. The buried line would follow an existing 2 track through the S½SE¼ of Section 21 and into the SWSW of Section 22. A storage tank and stock water tank would be located at this point in Section 22. The pipeline route cuts through the NW corner of Section 27 along the ridgeline where an existing 2 track is located. The pipeline would follow the 2 track ridge road along the spine of the ridge through the E½E½ of Section 28, exiting into BLM land at the border of the SWSESE of Section 28. Length of pipeline on Trust Land would be approximately 1.8 miles. The purpose of the new line is to provide upland water sources to a dry area.
