As noted in Section III "Comments-Compliance", under Hydrologic Balance, sediment pond A, as of the date of the inspection, had been cleaned and was ready to receive spring runoff. Although C ditch was temporarily blocked, it has since been cleared and positive drainage has been re-established into the main pit. Groundwater continues to seep into the pit. The amount of inflow into the pit has increased significantly due to surface runoff. Water is currently being pumped from the pit into B pond. Ponds A and B have both dis- charged during this spring runoff season. Pond A stopped discharging on P1arch 23, 1984. Pond B will continue to discharge as a result of the pumping. Water samples have been, and will continue to be, taken as required by N.P.D.E.S. permit number CO-0036854. Walden Coal Company remains committed to stabilizing topsoil stockpile C through the use of hay bales placed within the rills. This work can not be done at this time due to muddy conditions at the site. The bales will be staked into place as soon as conditions permit, prior to the heavy summer rains. Sage grouse continue to be active in and around the permit area in areas which are clear of snow. I hope that this letter has clarified 4lalden Coal Company's position on the issues discussed in your inspection report. If you have any questions, please do not hesitate to call. Sincerely, kay•James Resou~~ces hlanager
