Public Notice: Source Material License Amendment Application - Lost Creek ISR LLC, WYSUA-1598, TFN 7 1/215

Lost Creek ISR, LLC, of 1478 Willer Drive, Casper, WY 82604, has applied for an amendment to Source Material License WYSUA 1598 from the Land Quality Division of the Department of Environmental Quality of the State of Wyoming.  The license area for the mining of uranium is located in all or portions of Sections 16-20 and 29-31 of T25N, R92W and Sections 13, 24 and 25 of T25N, R93W.  The Lost Creek Mine is within the USGS Battle Spring, Osborne Well, Antelope Reservoir and Sooner Reservoir 7.5' Topographic Quadrangle Maps, Sweetwater County, Wyoming.   The existing Lost Creek Mine processing plant is in the northeastern corner of the Great Divide Basin approximately 17 miles southwest of the town of Bairoil, Wyoming. The mining operation began August 2013 and is estimated to continue until 2037. The land, after mining, will be returned to livestock grazing and wildlife. The amendment clarifies language in the license and corrects conflicting reporting/monitoring requirements.

Information regarding this initial draft decision and the application may be reviewed in the Office of the Land Quality Division, Department of Environmental Quality in Cheyenne or the Sweetwater County Clerk's Office in Green River, Wyoming.

Objections may also be submitted by the same deadline via the Land Quality Division’s electronic comment portal at https://lq.wyomingdeq.commentinput.com/. Only the amendment is open for public view. If an objection specifically requests a public hearing with the Department and is found to be an aggrieved part as defined in W.S. §35-11-103(a)(vii), a public hearing shall be held after the final date for filling objections. The Wyoming Oil ad Gas Commission will be mailed a copy of the application mine plan map as required in W.S. §35-11-406(j).
