<br />EXHIBIT D: Mining Plan <br />Ormiston Gravel Pit, M-94-048 <br />The Ormiston gravel pit, consisting of one major phase, broken down into two sub- <br />phases, is approximately 28 acres and has been mined since 1990. It is estimated that <br />phase 1 will continue to be mined for 26 years, to the year 2025. The San Juan National <br />Forest has indicated a t 20 acre second phase on their mining plan map to the west of <br />phase 1. Ifthis phase is mined in the future it won't be for another 25 years, at which <br />time a technical revision or appropriate application will be submitted to the DMG. <br />The San Juan National Forest Setice issues Special Use Permits in 5 year increments. <br />The current Special Use Permit expires the 315` of December 2002. At the time of <br />expiration the Forest Service will renew the permit until mining and reclamation <br />operations for the Ormiston Pit are complete. A copy of the Special Use Permit is in <br />Exhibit N: Source of Legal Right to Enter. A copy of the Forest Service's mining plan is <br />attached to this exhibit. <br />The mining of the Ormiston Pit is a surface mining operation. The topsoil ranges across <br />the site from 0 to 6 inches in depth and the overburden is estimated to be between 12 to <br />24 inches deep. A bulldozer is used to scrape the topsoil and overburden and stockpile it <br />on site. The topsoil will be seeded and, if needed, fertilized in order to prevent erosion <br />and control weed growth. The overburden is stockpiled on the mined slopes where it will <br />be smoothed over and used to construct 3:1 slopes around the edges of the pit. <br />The gravel deposit is estimated to be 40 feet deep and will be mined and processed on <br />site. Processing operations consist of screening and crushing. A crusher, filled by front <br />loaders, will be used to produce various aggregates for use in road construction. An <br />assortment of rip-rap will also be stockpiled and used in road construction projects. The <br />mined products are stockpiled on site near the entrance of the mine, in the staging area. <br />There can be three stockpiles at times -for the Forest Service, Montezuma County and <br />Dolores County; stockpile locations may move as phase I is mined. No water is used in <br />the mining operations at the Ormiston Gravel Pit. <br />At this time mining operations have progressed to the middle of phase 1 (sub-phase 1). <br />This sub-phase will be mined along the southwestern edge and then along the eastern <br />half, so that the eastern half of the entire Phase 1 area will be mined and ready for <br />reclamation when the current permit expires. The remaining portion of phase 1, sub- <br />phase 2 (west of sub-phase 1), will not mined until approximately the year 2010. It will <br />be mined from the south to the north. <br />There is an access road to the pit, which will be reclaimed when mining operations are <br />complete. Forest Service Road 521 services the access road and is therefore within 200 <br />feet of the mine boundary. There is a signed agreement between Montezuma County and <br />the San Juan National Forest stating that the County shall maintain the road during <br />mining operations and would be responsible for any damages. (please see attached Forest <br />Service mining plan). <br />
