CO-0000213, NEW HORIZON MINE <br />Dear Mr. Kubic: <br />WFU hereby requests that a new Outfall No. 008 be added to the current permit and approved for <br />discharge. The outfall will be located approximately 575 feet to the east of the Outfall 007. It will <br />serve as an alternate discharge point for Pond 007. The purpose of the alternate discharge point <br />is to pump the water from the discharge point and reuse it for irtigation purpose. A small dam has <br />been constructed in the Calamity draw to collect this water. <br />The pertinent data for this outfall are as follows: <br />Outfall No. <br />Source of Water <br />Treatment Type <br />Designed Storage Capaaty <br />Design Basis <br />Precipitation Event Volume <br />Discharge to <br />008 <br />Mine pit, surface runoff <br />Settling Pond <br />8.71 acre-feet <br />10-year, 24-hour event plus 3-year sediment storage <br />8.03 acre-feet <br />Calamity Draw <br />I am enclosing a revised Figure 1 to show the proposed discharge point along with the existing <br />discharge point. <br />If you need additional information, please advise. <br />Sincerely, <br />~~ti ~ti~ <br />Murari P.
