Box 1389 <br />Canon City, CO. 81212 ~J~. p'_.f }S " Z <br />Dear Bill, l~hr~3~ 1~'~~ <br />This is in reference to the renewal of the 2 limited impact mine site reclam- <br />ation plans for sites located in Custer County. The first site is north of State <br />Highway 96 in Silver Cliff and the second is approximately 1 mile straight north <br />of Westcliffe and north of the county landfill. <br />After the area has been banksloped to grades not exceeding 9:1 and topsoil has <br />been replaced to a depth of 6-8 inches, the following seeding rates are recommended: <br />Variety Species % in Mixture Rate/Ac. PLS <br />Arriba Western Wheat 60 9.6 lbs. <br />Pasture Little Bluestein 20 1.4 lbs. <br />Redondo Arizona Fescue 20 0.9 lbs. <br />11.9 lbs/ac PLS* <br />*PLS=Pure Live Seed= % Purity X % Germination. It may require 15 or more pounds of <br />bulk seed quantity per acre to equal 11.9 pounds of pure live seed. Seed dealers <br />should be able to figure this for you. <br />This seeding rec~ndation is based on drilled rates. If a broadcast method of <br />seeding is used then the rate will have to be doubled and the seed raked into the <br />soil. Seed should be planted to a depth of ~ to ~, inches, any deeper than this could <br />result in lack of adequate germination. <br />After seeding, the area should be mulched with 4000 lbs/ac. of meadaa hay for <br />stabilization. Timothy and RedtAp hay would probably be best since there is less of <br />a chance for them to germinate under dryland conditions. All mulch should be crimped <br />into the soil to prevent it fran blowing away. <br />The area should then be protected from people, vehicles and livestock until the <br />native perennial grasses have become well established. This will take a minimum of <br />2-3 years. In the meantime, the site should be fenced off to prevent indescriminate <br />access. <br />If I can be of any further assistance, please contact my office. <br />O Tne soil Conaervalion Service Sinc ely <br />U .a an agency o1 the Page 4 <br />~ DeVenmenl of Agriculture <br />Alan R.
