This plan would mitigate the problem noted during your last <br />monitoring inspection of the clay pit on August 24, 2000. <br />To prevent siltation of the roadside ditch, a tlu-ee-foot high silt fence would be installed <br />along the west base of the stockpile (see attached map). Then to control erosion, the <br />stockpile would be broadcast seeded this fall with both Yuma Winter Wheat as a cover <br />and Standard Crested Wheat grass for final vegetation. The seed application rates would <br />be 30 pounds PLS/Acre for the winter wheat and 14 pounds PLS/Acre for [he crested <br />wheat grass. The use of cover vegetation and a fall application should have a better <br />success rate than the past seeding. <br />Please contact me at (7l9) 542-3278 if any further information is needed. <br />Sincerely, <br />~~ <br />E.C.
