Tierra Piedra Ranch LLC <br />Tierra Piedra Gravel Pit <br />EXHIBIT "C"-MINING PLAN <br />a. It is anticipated that mining will commence in April or May of 2009. It will be an <br />intermittent operation as it will provide construction materials as needed for local <br />projects. Pursuant to Section 34-32.5-103(11)(b), C.R.S., operations at this gravel <br />pit will resume within at least one year from a date of temporary cessation. In <br />addition, the affected lands will likely be used for gravel pit operations less than <br />180 days per year. <br />b. The estimated depth to which soil, suitable as a plant growth medium, will be <br />salvaged for use is 2.5 feet. Two test pits in this area confirm topsoil depth. <br />Topsoil to be stripped, salvaged, and stockpiled along pit perimeters (at top of <br />slope) where shoreline of reclaimed pond is to be located. The bulk of stockpiled <br />topsoil will then be transported to other locations on the ranch and reapplied <br />immediately. The remaining stockpiled topsoil to be utilized for reclamation will <br />be seeded with mix recommended by MRCS. Stockpiles will have a maximum <br />slope of 1:l and will be stabilized against erosion as necessary. There may be <br />some very temporary stockpiles of topsoil at various convenient locations along <br />road, on the floor of the pit, and in the processing area. <br />c. Overburden is minimal. All material below topsoil to be mined and processed. <br />There will be no stockpiles of waste rock or overburden. <br />d. The thickness of the deposit to be mined is approximately 30 feet. <br />e. Major components of the mining operation are an access road, gravel pit, and <br />processing facilities (crusher and screener). Processing facilities to be located <br />outside of gravel pit at southern portion of project area. No offices or buildings <br />will be installed for this operation. <br />f. The project area is 6.4 acres (including new access road). The excavated gravel <br />pit is 4.8 acres. There will be no mine benches or impoundments. Excavation <br />will commence at northwestern side of pit and work southeasterly. Stockpiles of <br />excavated material will be located at southern end of project area. <br />g. Existing and proposed roads will have a 10-12' running surface with 6-10" of 3" <br />minus gravel. Specifications of existing and new roads are determined by <br />Archuleta County standards, as this project must receive county approval. <br />Stormwater BMPs will be installed along new access road and along excavations. <br />h. Water for this project will be obtained from the Tierra Piedra River via water <br />rights of the landowners. Water will be used for occasional watering of haul <br />roads and ramp areas. It is estimated that 1000-2000 gallons of water per day <br />may be utilized. <br />i. Groundwater will be encountered while excavating the gravel pit. Excavation <br />will generally be "wet" with backhoe or other method of extracting material from <br />at or below the water level. Minimal dewatering is anticipated, due to expected <br />infiltration capacity of remaining materials. When de-watering becomes <br />necessary, pumps will remove excess water from the pit. This water will be used <br />for irrigation of the adjacent hay field.
