construction company <br /> RECEIVED <br /> AUG 2 6 2024 <br /> RULE 3.1.5 9 Colorado Division of Reclamation, <br /> INERT FILL NOTICE ( ( 1� Mining and Safety <br /> Fountain Pit - M-1982-155 <br /> During the life of the mine Schmidt Construction Company will <br /> import inert materials as defined in Rule 1 . 1 (20) , into this <br /> mining operation. Much of the imported material will be natural <br /> sand and rock or aged recyclable asphalt and concrete. Most of <br /> this material will be processed and sold and not remain on the <br /> site. Some imported materials may be sued of roads or placed in <br /> areas where sloping is to be done . If courser material is used <br /> for backfilling it will be covered with finer material and <br /> revegetated where required by the permit. If the material is <br /> good dirt, we will use it to supplement the topsoil needs for <br /> the mined area. <br /> The amount of material to be imported is unknown because it will <br /> be moved in as it becomes available. We will record the volume <br /> imported each year and keep a running total of sales -vs- <br /> imports, so if needed, the Division will know how much was <br /> imported and how it as disposed of. We will continue to import <br /> inert fill until reclamation is complete, or we no longer have a <br /> source. <br /> No specific compaction rates are proposed for the areas where <br /> fill will be used for reclamation. The material usually <br /> available contains smaller pieces of concrete, or dirt mixed <br /> with the larger pieces of the same material . This makes it very <br /> difficult to achieve a specific compaction rate. While we take <br /> no action to reach a specific compaction rate, the way the <br /> material is placed tends to compact it . We run heavy equipment <br /> over the filled area during the filling process and the material <br /> is compacted as a result . Stabilization of this fill material <br /> is not a concern because of the way it is placed. What voids do <br /> remain are usually under large pieces of material and little <br /> settling is possible. The depth of the fill will not be so <br /> great as to affect offsite lands if settling occurred. <br /> Schmidt Construction Company <br /> 2635 Delta Drive, Colorado Springs, CO 80910 <br /> (719) 392-4207 <br />
