This <br />grading will be done witha Caterpillar D9 dozer, and the rate of <br />production will be very similar to that estimated for the rough <br />grading at the tipple area. <br />1. Production at Tipple Area = 16.2 hrs = 2.0 acres /hr.* <br />8.28 acres <br />2. Acreage to grade around shop area = 21.59 acres <br />3. D-9 Dozer Cost = $77.66/hr <br />Rough Grading Cost: <br />$77.66 hr, x 2 hrs/acre x 21.59 acres = $ 3,900 <br />*From Kerr Tipple Amendment Application (page 49(b)) <br />Topsoil Stockpile Area Revegetation <br />•. <br />1.
