<br />Mr. Jay Lucas <br />April 20, 1982 <br />Page 4 <br /> <br />include skunkbrush sumac and wax currant. Other species could be added <br />to this mix depending on the success of the experimental plantings referred <br />to above. <br />The operator has retained a professionally qualified revegetation management <br />company to install and maintain the reclamation plantings. The operator <br />requests that the recommendations of this firm be followed for specific <br />plantings based on aspect and bench level of the quarry. <br />The anticipated survival rate of shrub species planted and not irrigated <br />is expected to average forty to sixtq percerr~ The projected survival rate <br />is based on planting during the period recommended by the USDA SCS for this <br />area. <br />The majority of the drainage area wildlife habitat mentioned, and Strain <br />Gulch in particular, will be removed during the mining operation and will <br />not be restored during reclamation. Surficial runoff presently flowing <br />down Strain Gulch will be routed around the edge of the quarry at elevation <br />6930 on the first bench down from the top of the quarry as shown in Water <br />Resource Consultants revised drainage plan and diverted into Unnamed Gulch <br />B, or Basin B. The mining plan will thus effectively remove the majority <br />of the existing riparian vegetation. However, the operator has proposed <br />expanding the variety of shrubs to increase the cover types and food sources <br />available. Concern was expressed by the Division of Wildlife that access <br />between each eighty foot high highwall be provided to permit animal movement <br />through the quarry. Each bench will be connected to the adjacent benches by <br />an access ramp which will be constructed during mining to provide access for <br />heavy machinery. <br />Very truly yours, <br />RINDAHL & ASSOCIATES <br />~g <br />Ann B.
