EXHIBIT C UPLAND GRAVEL MINING PLAN 1.) DEPOSIT EXTRACTION: The gravel depth is variable due to the eroded surface of the deposit which is estimated to be 28 feet thick at the highest point. Very little or no overburden or top soil exists on the site which could be used for reclamation. The underlying Mancos shale will be exposed when the gravel deposit is removed and shall be re-conditioned to support re- vegetation. Extraction will begin in Unit 1 in the Fall of 2001, at the lowest elevation of the deposit near the end of 35 Road extension and proceed uphill in 30,000 ton units to the Northeast through Unit 7 to the end of the deposit at a point approximately 560 feet East of 35 Road and 290 feet South of D 1/4 Road. A natural berm of gravel (Units 8 and 9) separating the pit from view and buffering existing and proposed residences sites will be left in place for the very last extraction estimated to be in 2010 or earlier. A two (2.0) acre stockpile and storage area (180'x350') with scales and a sales office will be located in unit 1 and 2 adjacent to the extension of 35 Road and will be left graveled and un-reclaimed for the life of the pit. Re-vegetation shall take place on the remainder of the mined area in 2.0 acre intervals within 6 months of completion of excavation. The re-vegetation shall be guaranteed for a period of three years or until firmly established. No more than four (4) acres shall be un-reclaimed at any time during the life of the pit. The estimated life of the deposit which contains an estimated 257,000 ton shall be four (4) years @ 70,000 annual ton extracted to nine (9) years @ 30,000 annual ton extracted. The actual life of the gravel extraction operation will depend on the demand for the construction materials. The Denison Pit located Southwest of this site has been in operation since 1984 (16 years). An access road 22 feet wide and 75 feet long to the site will be directly to the paved intersection of 35 Road and Upland Road. Dust from haul roads and mine area shall be suppressed with water trucks and/or sprinkling systems as needed with water from the storage pond. Erosion control ditches shall be constructed at the gravel contact line with Mancos Shale and routed to a water impoundment basin (Part of Unit 1 & 2) to insure there will be no discharge of storm water or sediment from the site. Extraction will be done with an excavator and loader.
