Division of Reclamation Mining & Safety Mining & safety 1313 Sherman Street - Room 215 Denver, CO 80203 RE: Energy Fuels Coal, Inc. — Southfield Mine — Permit No. C -1981 -014 Technical Revision No. 43 (TR -43) Request to Terminate Water Monitoring Program at Southfield Mine Dear Rob Zuber: Energy Fuels Coal,, Inc. (EFCI) is submitting 3 copies of this revision request to terminate all surface and groundwater monitoring at the Southfield Mine in Fremont County Colorado. Given that the Southfield mine is currently in Year 10 of the Ten Year Reclamation Liability Period, the request to terminate the water monitoring program is warranted and appropriate based on the current and long -term monitoring results and for preparation for the upcoming final bond release request. Purpose of this document is to present a demonstration to that end which indicates that all of the requirements and conditions of the Permit C- 1981 -014 (Permit) associated with surface water and groundwater monitoring have been satisfied. This submittal is essential for the timely acceptance, review and approval of the upcoming final bond release request for the Southfield mine. Following is an overview of the Southfield operations. Surface and Groundwater Monitoring: Active mining and coal production operations at Southfield ceased in December 2000. The mine portals and shafts were sealed in 2001, demolition of the mine facilities occurred in 2001 — 2002, most of the associated disturbance were backfilled and reclaimed by 2002, permanent seeding of grasses, shrubs and fortis occurred in the fall of 2003 and approximately 1,800 shrubs and tree seedlings were planted in the spring of 2004. Water monitoring at the mine has been accomplished through both surface water discharges from sediment ponds and in groundwater monitoring wells. A permit to allow surface water discharges was obtained from the Water Quality Control Division under the Colorado Discharge Permit System, Permit No.COG- 850045 for the mine site and Permit No.COG- 850006 for the former Loadout site. Surface water monitoring has been continued through the reclamation phase for Pond No. 4 and Pond No. 5 at the mine site and Ponds L1 and L2 at the former Loadout site. Former ponds No.l, No.2 and No.3 at the mine site were reclaimed during the demolition phase of the facilities area during 2001 — 2002. Ponds No.4 and No.5 at the mine were redesigned during 2002 as approved self dewatering ponds wherein the pond's primary discharge points are through a vertical standpipe when /if the design water volume of the im0oundment capacity is reached as opposed to the former design wherein water was manually allowed to discharge through a gated horizontal culvert near the bottom of the pond. Since the redesign of the ponds, (2002) there has been no known discharges from the ponds due to the design TR -43 Revised: 10/2014
