BESTWAY <br /> CONCRETE&AGGREGATE <br /> April 7,2016 <br /> Division of Reclamation,Mining&Safety <br /> Mr.Michael Cunningham <br /> 1313 Sherman St,Room#215 <br /> Denver,CO 80203 <br /> Dear Mr.Cunningham; <br /> RE: Bestway Concrete,Inc.-Rocky Flats Pit <br /> M.L.R.B.Permit#M-1987-113 <br /> Technical Revision ditch move <br /> Attached is a Technical Revision form and supporting information sheet and the Fee of$216.00 for requesting a minor <br /> change to the reclamation plan that relocates the Church&McKay ditches that bisect the mine to a ROW along the west and north <br /> lines. The updating Reclamation Map shows this change.This request is in conjunction with a similar Technical Revision request <br /> filed by The Lakewood Brick and Tile CO.for their mine the Church Pit-M-1979-045.The original plan thought that the ditches <br /> would be merged into one ditch and relocated along the west and south sides of the Bluestone Pit permit area,then cross the south end <br /> of the Church Pit and the south and east sides of Rocky Flats Pit,returning to their original ditches in the northeast corner of the <br /> Rocky Flats pit. When that permit was released,it was determined by the owners and mine operators that it was not feasible to use <br /> this route so the plan was changed to move them to the north side of the two remaining mines. <br /> Attached are the documents and plans showing,approval for the move by the ditch owners,Broomfield;the surface owners, <br /> The Department of Energy;and the mineral owners,Church Ranch. The Reclamation Map also shows how the southern end of the <br /> mine will be reclaimed considering the amount of overburden we are encountering and returning to the mined area. At this time we <br /> can only estimate how much will be refilled but the plan is to continue filling from south to north until mining ends. We originally <br /> estimated the mine would be 60 feet deep but as mining progresses we are finding the gravel reserves are much deeper than originally <br /> thought and plan to maximize extraction by going deeper. <br /> If you have any questions or need more information please call me. <br /> Respectfully Submitted, <br /> Mark Johnson <br /> Vice President <br /> cc Charlie McKay-Church Ranch <br /> Perry McKay-Church Ranch <br /> Tom Murray-Lakewood Brick <br /> Steve O'Brian-Environment,Inc. <br /> City of Broomfield <br /> DOE <br /> file <br /> enclosures <br /> Bestway Concrete and Aggregate,301 Centennial Drive,Milliken,CO 80543 <br />
