EXHIBIT D: Minine Plan <br />Hocker Construction, LLP Gravel Pit <br />The Hocker Construction gravel pit, consisting of a staging azea, 4 mining phases, <br />sediment ponds and two access roads, is on an approximately 115 acre pazcel of land with <br />81.7 acres to be permitted and 62.5 acres affected by mining. The site is located in La <br />Plata County, near industriaV commercial uses, including two gravel pits and a concrete <br />batch plant. The gravel pit will be mined in four phases. The phases will start at a <br />central location near a gas well on the property, and then proceed in a north, <br />northwesterly fashion for the first two phases, phase 1 and phase 2. The operation will <br />then return to the center of the property and begin mining in a south, southeasterly <br />direction in phase 3. Finally, the mining operation will cross CR 321, and begin on the <br />4~' and final phase. Mining for phase 4 will start at its eastern edge, and proceed in a <br />westerly direction. These phases will be mined in the order set forth on the mining plan <br />map (Exhibit C) and take approximately 3-5 yeazs per phase to mine out, giving to pit a <br />life of 12-20 years. Scales and a scale shack will be erected at the site. Mining is <br />expected to commence in the Spring/Summer of 2005, and finish in the Fall of 2025. <br />Mining operations <br />The minutg of the Hocker Construction gravel pit is a surface mining operation. A <br />bulldozer will be used to collect the topsoil and overburden. The topsoil depth, ranging <br />from 0-1 inch, will be stored on site and seeded to prevent erosion and weed infestation. <br />The overburden depth is estimated to be 10 to 20 feet, and will also be stored on site. <br />The overburden will be used to create a berm on the eastern edge of the miniug area as a <br />visual, sound and drainage buffer. Any excess overburden will be stockpiled on site and <br />or sold. Overburden will be compacted and seeded to prevent erosion and weed <br />infestation. During reclamation, it will be used to recreate 3:1 slopes from the mining <br />highwall. The gravel deposit is estimated to be 10 to 20 feet below the overburden, and <br />up to 20 feet deep. The highwall will range from 20 to 40 feet high, and vary in width <br />from 50 to 250 feet. <br />The Company will locate up to three processing plants on-site at any one time. There <br />may be a concrete batch plant located within the permitted azea, at a location that is <br />
