~ ~~a u r~~~ ~I a~ r~ I wand & C h~ ~ ~ ag ~ r~v~ N 1412 County Road 311 I NNN New Castle, GO 81647 (970} 876-2397 Fax (970) 876-5232 INERT FILL NOTICE (RULE 3.~.s(9)) Goldman Pit - M-78-279 From time to time over the life of the mine we may import inert materials as defined in Rule 1.1(20), into this mining operation. It will be used to partially construct the slopes that will be left when mining ends. If courser fill is used it will then be covered with finer material and revegetated where required by the current permit. If the material is good dirt we will use it to supplement the topsoil needs for the mined area. As ex- plained in the original permit application there is little soil on the site and any imported dirt will only increase the chances of revegetation being successful. The reclamation plan approved will not be changed and we will continue to do reclamation concurrent with mining. Tlie fill, IF AVAILABLE, will be used to create the slope or as a site berm along the county road. Sloging will not be delayed if fill is not available since the fill will supplement material on the site at this time. The exact amount of material to be imported is unknown. We will report the volume imported each year in the annual report and keep a running total so the Division will know how much and where it has been placed. Importing fill will begin immediately upon notification by the Division that this notice is acceptable. We will continue to import inert fill until reclamation is complete or we no longer have a source. Portions of the slopes around the perimeter of the excavated area will be built with imported fill material. The dirt imported will enhance reclamation success, since there was little topsoil on the site when originally permitted. No specific compaction rates are proposed for the fill. The material usually available contains smaller pieces of concrete, or dirt mixed with the larger pieces of the same material. This makes it very difficult to achieve a specific compaction rate. While we take no action to reach a specific compaction rate, the way the material is placed tends to compact it. We run heavy equipment over the filled area during the filling process and the material is compacted as a result. Stabilization of this fill material is not a concern because of the limited amount used in the elopes and the way it is placed. What voids do remain are usually under large pieces of material and little settling is possible. No structures will be built on the fill, nor will the depth of the fill be so great as to affect offsite lands if settling occurred.
