Box 1298 <br /> Glenwood Springs, CO 81602 <br /> RE: Modification of NOV C-93-130 <br /> Dear Ms. Delaney: <br /> Enclosed is a modification for NOV C-93-130. As you may recall, <br /> the NOV was originally issued in response to TDN X-93-20-244-2 TV-1 <br /> from the Office of Surface Mining. As originally written, the NOV <br /> required Mid-Continent to identify and address erosion problems on <br /> the outslopes of the mine portal benches. The abatement is being <br /> modified to also address treatment of surface runoff from the <br /> outslopes. <br /> Disturbance of the outslopes has been the subject of a number <br /> discussions over the past year. The presently approved reclamation <br /> plan and abatement of NOV C-93-130 will both entail new disturbance <br /> of the outslopes. Consequently, some means of treating surface <br /> runoff for sediment control will need to be implemented. I would <br /> encourage Mid-Continent to review possible plans for sediment <br /> control with the Division prior to devising and submitting plans. <br /> If you have any questions, please contact me or Tony Waldron. <br /> Sincerely, / <br /> C/ <br /> Larry P. Routten <br /> Senior Reclamation Specialist <br /> enclosure <br /> c: Tony Waldron <br /> c: \wp51\10493 <br />
