Tierra Piedra Ranch LLC <br />Tierra Piedra Gravel Pit <br />EXHIBIT "D"-RECLAMATION PLAN (revised) <br />Gravel pit to be reclaimed as a pond for wildlife habitat. <br />a. Overburden is minimal and therefore requires no stockpiles. <br />b. The maximum gradient of the slopes will be 3:1. The floor of pit to be left at final <br />grade as mining progresses. <br />c. Revegetation <br />L Topsoil to be replaced to minimum thickness of 6" in areas outside of <br />reclaimed pond. <br />ii. Topsoil will be replaced over final graded areas (along pond banks, <br />etc) after completion of excavation activities. Reclaimed areas to be <br />roughened prior to replacement of topsoil. <br />iii. No shrubs or trees will be planted. Reclaimed areas will be seeded <br />with 20-25 lbs./acre with smooth brome, spreader alfalfa, sainfoin, and <br />crested wheat per landowner specification. <br />iv. The application method for the grass seeding will be with a no till drill. <br />V. No mulch will be necessary for reclamation. <br />vi. No shrubs or trees will be planted. <br />d. The gravel pit will be reclaimed as a pond for wildlife habitat. Slopes of the pond <br />from 5 vertical feet above to 10 vertical feet below the expected average water <br />level will not be steeper than 3:1. The shoreline of the pond will be irregularly <br />shaped so that it appears as a natural feature. The DOW has been contacted for <br />recommendations (copy of letter attached). All disturbed areas outside of the <br />gravel pit will be reclaimed/ revegetated and will have a slope gradient of 0-1%. <br />e. A stable configuration or hydrologic balance will be achieved by an average 3:1 <br />excavated slope of the pit faces on all sides. Excavated slopes will generally be <br />parallel to each side of the permit boundary. Surface water will infiltrate into the <br />terrace alluvial deposits at the edge of the pit and is presumed to flow into the <br />Piedra. River as subsurface flows. Stormwater BMPs will be utilized to prevent <br />any runoff from affecting off-site locations. All areas outside of the reclaimed <br />pond will be reclaimed with a final grade slope of 0-1%. <br />2. Reclamation will occur after completion of all excavation activities. <br />a. 25 hours for reclamation of project area outside of gravel pit <br />i. Tractor, 25 hours @ $90/hour = $2250.00 <br />ii. Tractor/seed drill, 10 hours @ $95/hour = $950.00 <br />iii. Seed mix for 1.0 acre = $200.00 <br />b. Total Estimated Reclamation Cost = $3400.00
