The highwall grading volume remained the same but a D8 dozer was used to slope the pit <br />walls [0 5:1 so the estimated costs were reduced to $11,230. <br />2. The Rapid-Ex bid to replace and grade the 1200 cubic yards of topsoil was acceptable so it <br />was used in the revised estimate. <br />3. Ripping costs increased slightly even though a DS dozer was used. <br />4. Reseeding costs remained the same as the original estimate because the Division has <br />determined that a certain amount of vegetation will fail, so interseeding will be necessary. <br />5. The mob/demob bid from Rapid-Ex was acceptable and was used in the revised estimate. <br />You state that 30% failure rate for seeding is too high. I disagree. There have been, and are, <br />documented sites in Custer county that required to be totally reseeded or require some amount of <br />interseeding in order to achieve adense/diverse stand of grass that will meet the reclamation <br />requirements of the ActJRules. There is one site immeadiately north of Westcliffe that had to be <br />totally reseeded because of cheatgrass problems. <br />The revised financial warranty requirement, using numbers from the Rapid-Ex bid document and <br />previously calculated Division numbers, is $30,700 (rounded). A 60 day notice letter will be <br />mailed in the next day or two. You will have 60 days from the date of the notice letter to submit <br />the additional financial warranty (pursuant to Rule 4.2.1(2)). If you disagree with the office <br />
