~. <br />2 <br />4) The Division estimates cost of reclamation of these four <br />de-gas wells and sump dewatering hole at $16,796.00. This <br />is based on sealing the holes, regrading and topsoiling <br />the pads and roads, and revegetation using WF-U's seedmix <br />shown in Table V-14 of the permit. If Western Fuels <br />disagrees with this value, please provide more detail of <br />Western Fuel's proposed reclamation method. <br />Information required by the Division pertaining to construction of <br />sump dewatering hole #3 and associated process pond are as follows: <br />5) Discussions with representatives from the Colorado <br />Department of Health confirm addition of outfall #026 <br />which coincides with SDH #3. What will be the volume or <br />rate of discharge from this point? Over what time <br />duration will discharge occur at outfall #026? The <br />Division will also require written documentation of CDOH's <br />approval prior to proposing a decision on establishment of <br />this new discharge point. <br />6) WF-U's revision proposes placement of a process pond below <br />outfall #026. No further information about this process <br />pond is provided. The Division will need to know details <br />of the construction, dimensions, volume, discharge <br />structures, location, materials, inflows, outflows, <br />projected water quality, and time period requested to <br />install this process pond. Will discharge from this pond <br />be to a stable channel? Would Channel reinforcement be <br />necessary? <br />Please be aware that Rule 4.05.9(2) will need to be met in <br />construction of this structure. Discharge from this <br />structure will need to comply with Rule 4.05.2(1). <br />Submittal of this information would best be handled as a <br />technical revision. <br />If Western Fuels-Utah will be unable to provide this information to <br />the Division within adequate time for the Division to review prior <br />to the August 18, 1992 proposed approval date, we suggest WF-U <br />request an extension of time for review of the submitted <br />information. If there are any questions I can clarify, please <br />contact me. <br />Sincerely, <br />'i_i-~ <br />Janet $. Binns <br />Reclamation Specialist <br />Enclosure <br />M:\wp51\JHB\C81018MR.73b <br />
