• Postmining Pond Retention <br />As described in the Mine Facilities section, Pond 007 will be retained for use by the landowner and <br />the embankment of 5'h Street must remain for ongoing use of the road. See Attachment 2.05.3(3)- <br />16 Demonstration of Retention of Pond 007 for details <br />Pond 008 was constructed in an area which contained three small stock ponds on the Burbridge <br />property. The landowner has provided a letter stating that he would like Pond 008 to remain to <br />replace the three ponds which existed in the pre-mining condition. This letter is provided in <br />Attachment 2.05.4(2)(C)-4 at the end of this section. Compliance with Rule Rule 4.05.9(13) (a) <br />through (f) for pond retention after reclamation is enclosed in Attachment 2.05.3(3)-19. <br />Postmining Drainage Channels <br />• All major drainages in the New Horizon 2 area that are to be disturbed by mining activities will be <br />reclaimed to approximate the premining configuration and to blend with the undisturbed drainage <br />above and below the area to be reclaimed. Two pre-mining channels are encountered and <br />restored. These are called the Krill Channel on the easternmost portion of the mined area and the <br />San Miguel Channel which drains into the reclaimed area of Pond 007. Both of these channels are <br />shown on Map 2.05.3(3)-1 Surface Hydrology. The Postmining drainage channels will be designed, <br />constructed, and maintained to the following specifications: <br />1. Gentle sloping banks which shall be stabilized by vegetation; <br />2. Prevent additional contributions of suspended solids to streamflow and to runoff <br />outside the permit area; <br />3. Blend with the undisturbed drainage above and below the area to be reclaimed; <br />4. Safely pass the runoff from a 10-year, 24-hour precipitation event. <br />• (Revised July 2006) 2.05.4(2)(c)-8 <br />
