Amendment 001
The Department of Environmental Quality (DEQ) received an application for an amendment held by Schellinger Construction Company, Inc., (Schellinger) for the Essex Quarry, Operating Permit No. 00045. The quarry is located near Essex, approximately 28 miles southeast of West Glacier in Flathead County, Montana. The site is in Sections 33 and 34, Township 30 North, Range 16 West. The amendment area would cover a total of 20.6 acres, all of which would is proposed to be disturbed. With the existing permitted disturbance area, a total of 60.5 acres would be permitted for disturbance. The life of mine would extend to 2060. Schellinger would use trucks and heavy equipment to remove the stone used for riprap and ballast; blasting would be required about once per year.

Amendment 017
On March 30, 2020 Golden Sunlight Mine, Inc. (GSM) submitted to the Department of Environmental Quality (DEQ) an application to amend Operating Permit No. 00065. The amendment would allow GSM to reprocess tailings recovered from Tailings Storage Facility 1 (TSF-1) over a period of approximately 12 years using conventional excavation, loading, and conveyance equipment. The 26.2 million tons of tailings at TSF-1 cover an area of approximately 190 acres. Tailings would be recovered from TSF-1, then mixed with water to produce a slurry that would be pumped to the Flotation Plant in the existing Mill Building. The Flotation Plant would process approximately 6,400 tons per day of tailings. The Flotation Plant will allow recovery of residual gold values, reduce reactivity of the reprocessed tailings, and produce a sulfidic concentrate for market at a rate of approximately 455 tons per day. GSM would use the Mineral Hill Pit as a repository for disposal of reprocessed tailings. For final reclamation, a growth media cover will be placed on the tailings surface and seeded to control dust and minimize infiltration of precipitation. Flotation tailings fill material in the Mineral Hill Pit will have a surface area of approximately 35 acres. Implementation will not require a change in the approved water management system for the Mineral Hill Pit. Flotation tailings process solution combined with existing Mineral Hill Pit seepage and the bedrock aquifer will continue to be managed in accordance with the current approved system. GSM would continue to maintain the cone-of-depression in the groundwater table surrounding the Mineral Hill Pit through use of the underground sump. The existing dewatering system will effectively control seepage water from the tailings, ultimately pumping the sump water to TSF-2.

If approved, the amendment   would allow the Regal Mine to expand the existing open pit talc mine.  The permit boundary would increase from 243 to 380 acres.  The expansion would include, in part, a pit expansion of 45 acres and a waste rock dump expansion of 172 acres, some of which are already within the permit boundary.
The expansion would extend the mine life by approximately six years.  Eight million cubic yards of waste rock and one-half million cubic yards of talc ore would be produced.

Amendment 003
The Department of Environmental Quality (DEQ) received an amendment application from Sibanye Stillwater Mining Company on December 4, 2017, proposing to expand the impoundment at the East Boulder mine. The Sibanye Stillwater Mining Company operates this mine under Operating Permit No. 00149.

If approved, the proposed amendment would allow a “raise” of the currently permitted tailings impoundment.  The proposed amendment would raise the currently approved Stage 5 lift an additional fourteen feet in elevation and add 1.8 million cubic yards of tailings capacity. The amendment would add approximately 6.4 acres to the currently permitted disturbance area for a total of about 335 acres of disturbance.
