Board of County Commissioners <br />Libby Szabo <br />District No. 1 <br />Casey Tighe <br />District No. 2 <br />Donald Rosier <br />District No. 3 <br />NOTICE OF INTENT TO BACKFILL WITH INERT STRUCTURAL FILL <br />May 13, 2015 <br />TO: Colorado Division of Reclamation, Mining, and Safety <br />MINE NAME: Pine Junction Pit <br />MINE ID NUMBER: M-1977-245 <br />OWNER: Jefferson County — Road and Bridge <br />Jefferson County Road and Bridge would like to make the Colorado Division of Reclamation, <br />Mining, and Safety aware of our intent to use inert structural fill to maintain slopes, roadways, <br />and berms within the limits of the above named mine site. The material that is listed as inert <br />structural fill is pulled from ditches during the spring and summer months and then stockpiled <br />within the mine. When there is a need to reshape a berm, road and or slope the material is used <br />for that purpose. If the material is not needed then it is removed from the mine by Park County. <br />Approximately 24,000 tons of this material is hauled in to the Pine Junction Pit each year. <br />Approximately half that quantity is hauled off by Park County; the remainder is used for restoring <br />berms, slopes and roadways. <br />It is Jefferson County Road and Bridges intent to not use this inert structural fill during the <br />reclamation process of Pine Junction Pit. The current uses are for maintenance of the pit during <br />non mining periods. This material is in locations within the pit that will become part of the mining <br />process and will be mixed into crushed material or be removed from the pit prior to reclamation. <br />Issued By: <br />Michael W.
