January 9, 2015 <br />Tim Cazier <br />Colorado Division of Reclamation, Mining and Safety <br />1313Sherman St. Room 215 <br />Denver, CO 80203 <br />Re: South Asphalt Plant: DRMS File No. M- 2009 -004 <br />Adequacy Review Response- Technical RevisionNo. 1(TR -01) <br />Tim, <br />The following information is being provided in response to the preliminary adequacy review for this <br />plant site. <br />Imported material: Characterization <br />A. Potential Sources: Sources would generally consist of construction sites where the native <br />material is unsuitable for placing structures or roadways on top of. This could include <br />material from our own job sites or sites that other contractors are working on and are <br />purchasing other suitable materials from one of our pit sites. <br />B. Graduation Generalization: Fill material may be six inch minus material and most typically <br />will be two inch minus material consisting of clay, sand or general fill dirt. All loads are <br />inspected for trash and other unacceptable items and the loads are rejected if these items <br />are present. <br />C. Largest size: As noted above, the material will typically be smaller than two inches in size. <br />At times, we may receive rocky material but the material would not exceed 2 feet in size. <br />D. Organic Content: The majority of the material will be free of organics; however, some <br />material may contain grass strippings, which should not affect the fill site. <br />2. Final Contours: The reclamation map that is on file correctly depicts the final contours <br />expected for the site after mining is complete. The current and post mining grading directs all <br />run off from the north to the south, directed to onsite stormwater ponds. <br />3. Potential Sinkholes: All foreign materials that could potentially create voids in the fill will be <br />removed from any material placed in the mined area. Typically, the fill material is being placed <br />into the mined area from the top of the slope. The material fills at its natural angle of repose. <br />Complete compaction of the area will be achieved by the long term use of the area as an asphalt <br />materials storage yard. Once backfilled the entire mined area is subjected to constant heavy <br />truck and equipment traffic. Also large stockpiles of material will be stored on top of the <br />
