<br />$1500.00/acre including all materiels and ground work <br />preparation totaled $350.00/acre for a total reclamation coat <br />of $1850.00/acre or $55,500.00 for measures taken to minimize <br />impact of dump areas to neighboring lands during this time of <br />temporary cessation. The land reclamation project also <br />addresaess land use on a larger time frame in establishing <br />a long term native grass and schrub diversity which will add <br />to wildlife habitat improvements achieved to date on app. 30 <br />acres of previously mined land within the affected land <br />boundaries. Of the 100 acre of affected land within the <br />permited site, 30 acres are in a state of permanently <br />reclaimed static and 30 acres have been stabilized as <br />described above. This results in 40 acres of severely dis- <br />turbed ground, active mining areas which will remain so <br />during the time of temporary cessation. A projected cost of <br />reclaiming the remaining 40 acres based on its present <br />condition, not on a resumption of mining operations and <br />subsequent integration with ore extraction, would be in the <br />range of S4-5K/acre. On the other hand, any resumption of <br />mining for purposes of gypsum extraction would substantially <br />reduce the projected reclamation cost to about half that <br />amount ($2500/acre) due to the fact that much of the highwall <br />exposed at the present time is uncovered gypsum reserve. <br />It is fortunate that maintenance needs for the site are <br />minimal since maintenance capabilities are so. A springtime <br />review of soil moistere conditions will be performed so that <br />watering of first and second year tree and schrub seedlings <br />can be performed if needed. This should be performed at <br />several intervals throughout the summer of 1991 depending on <br />the local weather conditions. This type of maintenance could <br />be critical for the survival of seedlings planted in 1989 and <br />1990, but should be less in demand in 1992, again depending <br />on local moistere conditions experienced at that time. <br />December 1990 grass planting described above should not need <br />watering or other maintenance in order to develop into a <br />permanent vegetation cover. However, these areas will need to <br />be assessed for grassland establishment in the summer of 1991 <br />and may require additional planting, fertilization, and <br />mulching to insure an adequate vegetation cover. <br />Detailing a projected reclamation coat of presently disturbed <br />ground at the site is primarily a function of earthmoving <br />costs related to highwall removal and backfilling. These <br />projected cost will vary widely based on weather on not the <br />resource is utilized vs a massive backfilling operation and <br />as to the final highwall areas left intact as projected in <br />the original permit application. Certain highwall areas <br />within the mine zone must be removed regardless and will coat <br />more than the average $5K projection. The Copper Hill <br />highwall area, an area of five acres located within the mine <br />zone, may cost in the range of $15K/acre for highwall <br />I removal. <br />
