Mesa De Maya Pit Exhibits <br />County road segments that need base material, but the pit will remain active during these <br />idle periods. <br />a. Mining will commence in the spring of 2014 once all permits and other <br />requirements are approved and a means of producing road base materials is <br />secured. This operation will be active annually but less than 180 days per year and <br />will be in intermittent status. <br />b. Estimated depth of soil suitable as a plant growth medium is 2" to 4 ". Salvaged <br />soil stockpiles will be seeded in accordance Exhibit B a 1, 2 & 3. <br />c. There is minimal overburden in this area and it will be mixed into the material <br />that is fed the processing equipment. <br />d. The deposit thickness is approximately 10 feet. <br />e. The pit's western boundary is in close proximity to County Road 165.4. There is <br />an existing ranch road from 165.4 to the pit that will be utilized for accessing the <br />pit. Processing facilities may include, crushers, screening plants, loaders, trucks, <br />dozers, backhoes and motor graders. <br />f. The dimension of any significant disturbances such as pit excavations is <br />potentially the entire permitted area. No mine benches or impoundments are <br />anticipated. Stockpile dimension will vary but should not be of significant size. <br />g. Existing County Road 165.4 is approximately 18' wide. No improvements are <br />anticipated for this road except the placement of road base produced at this pit. <br />The existing ranch road is approximately 10' wide and 20' long. Improvements <br />will include using a motor grader to smooth the surface. No other improvements <br />are anticipated. <br />h. No water will be used in conjunction with the operation. <br />i. There will be no significant effect on the hydrology and water quality in the area. <br />There is no evidence of ground water that will be affected by the operation. The <br />site generates minimal runoff. If necessary, diversion ditches, berms and /or <br />sediment basins will be constructed to control surface runoff all in accordance <br />with this pit's storm water permit. <br />j. No injury to existing water rights is anticipated. <br />k. If refuse and acid or toxic producing materials are exposed, excavation operations <br />will immediately cease. Exposed areas will, without delay, be buried and covered <br />with other excavated material and compacted. <br />1. After reclamation, slopes will not be steeper than 3:1. The bottom of the pit <br />should be relatively level. Revegation of reclaimed areas will be done in <br />accordance Exhibit B a 1, 2 & 3_ <br />m. The deposit will be processed on site. A dozer, loader and/or trucks will be used <br />to push, load and haul topsoil to the topsoil stockpile. After the topsoil is <br />relocated, the dozer and loader will commence to excavate material (pit run). The <br />loader will dump the pit run into a hopper which feeds a portable crusher and/or <br />screen, dumping onto the flat belt(s) that dumps onto the stacking conveyor that <br />dumps the processed material on to the processed material stockpile. The initial <br />extraction will start in the western area of the pit and progress toward the southern <br />and eastern portions of it. After some duration, the processing equipment will be <br />relocated to another pit. During these periods of idleness, this pit needs to stay <br />active in intermittent status. When processing renews, the processing equipment <br />will be at different location (dependent upon deposits mined and available) within <br />the pit. <br />
