<br /> <br /> <br />Introduction <br />To remove a sediment pond and it's also- <br />ciated drainage ditches, a coal mine opera- <br />tor must demonstrate that the reclaimed <br />land is not contributing settleable solids to <br />streamflow outside the permit area in <br />excess of pre-mining levels. Kaiser Steel <br />Resources (Kaiser) has conducted an <br />analysis to demonstrate that reclaimed <br />Colorado Coal Mine (GCMG) Number 1. <br />Mine is not contributing more sediment to <br />Gordon Arroyo than was the situation <br />prior to mining disturbance. <br />Kaiser's analyses was conducted using the <br />SEDCAD+ software package. Use of this <br />software was recommended by the Colora- <br />do Mined Land Reclamation Division <br />(CM1:.RD). Kaiser feels the analyses clear- <br />ly demonstrate that the sediment control <br />to warrant the removal of sediment pond <br />number A and B. The following sections <br />of this report describe how the analyses <br />were conducted and present the results of <br />the analyses. <br />A.` rim'.: ~, r <br />
