<br />Page 2 <br />Mr. Schmieding <br />November 9, 1979 <br />c. Since most of the mined areas will be reclaimed as ponds there will <br />be little if any backfilling. The amount of land to be graded, top- <br />soiled and seeded will be approximately 59 acres. <br />d. As a result of on site review by a member of MLR staff, it has been <br />determined that 4" of topsoil should be sufficient to maintain re- <br />vegetation. <br />e. Water evaporation from ponds created by mining is not considered a <br />consumptive use and current plans are to not provide augmentation <br />for evaporative losses. <br />f. Per your recommendation, the reclamation plan will include cottonwood <br />and willow trees at 5 in a bunch 20 feet apart. <br />g. Per your recommendation, the seeding mixture will include tall <br />wheatgrass. <br />h. An average of 4 acres will be reclaimed each year. <br />Reclamation work will be completed after the final year of mining. <br />Maintenance of reclamation is expected to last an additional three <br />years. <br />3. Since a portion of the area to be left at the end of mining will be road- <br />way which is currently being used and the minimal amount of leveling <br />and topsoiling along the pond banks, the cost of reclamation per acre <br />would be something less than a totally revegetated area. <br />The cost of $500 may be somewhat low if mining costs are not included. <br />The operator would agree with increasing the cost to $1,000 per acre. <br />For the Empire Pit #77-534 <br />1. Mining Plan <br />a. Topsoil has already been removed and is on site. <br />b. The slope of mining will not exceed 2:1. <br />' C. See notes on sheet 3 of 4, extraction plan map. The plan is <br />v expected to be as shown. At a later date when the final plans <br />will be submitted to the board as a technical change if necessar <br />in approximately thirty years. <br />
