AvRY <br /> CORPORATION <br /> RECEIVED <br /> APR 2 0 2020 <br /> April 13`h,2020 DIVISION OF RECLAMATION <br /> Colorado Division of Reclamation, Mining and Safety MINING AN0SAFETY <br /> Attn: Patrick Lennberg, Environmental Protection Specialist <br /> 1313 Sherman Street, Room 215 <br /> Denver, CO 80203 <br /> RE: Pueblo East Pit M2000-041 TR 06 Preliminary Adequacy Review Response <br /> Mr. Lennberg, <br /> Please see the number responses below that correspond with the Preliminary Adequacy Review. <br /> 1. The technical revision requests the change in Phase IIB to be backfilled, replacing the current <br /> plan of overburden storage. Fremont requests that Phase II's current mining and reclamation <br /> plan be extended through Phases IIB, IIC and IID. The map included shows the phased mining <br /> that is being requested and accounts for the backfill necessary for each phase. The Phase II <br /> backfill needed is 507,097 cubic yards,which will come from Phase IIB overburden of 671,293 <br /> cubic yards. This pattern moves through the phases as the next phase provides backfill via <br /> overburden to the previous phase. This will reduce the cost of reclamation of each phase by <br /> moving the overburden once and near the worksite. Mining practices will remain the same <br /> through Phase II as it currently is permitted and is requested that a revision is approved to <br /> extend this mining practice through the remaining three phases. <br /> 2. It is requested that a revision be approved to allow for reclamation to continue through Phase <br /> IIB-IID as is currently permitted in Phase II. It is requested that Phases IIB-IID be removed from <br /> the current reclamation plan of reservoir. <br /> 3. Please see the attached mining and reclamation plan maps as requested. <br /> 4. Fremont intends to proceed in a phased mining operation with only two phases in various forms <br /> of mining and reclamation at any given time. As stated above,overburden material from one <br /> phase will supply backfill material for the previous phase. Fremont commits to contacting the <br /> division prior to advancing into an unbonded phase. <br /> Included below is a table showing the estimated reclamation costs of the two phases being open at any <br /> given time. <br /> ARY CORPORATION A&S Construction Co. 839 Mackenzie Ave. <br /> Fremont Paving and Redi-Mix, Inc.
