2.05.3 <br />Sediment pond K collects run-off from the batch weigh loadout and <br />surrounding area. Pond K is a typical sediment pond, capable of containing <br />the run-off from a 10-year event with a spillway system designed to handle <br />the peak flow generated by the 25-year storm event. However, pond K is a <br />dugout pond so it does not have a primary spillway. Dewatering will be by <br />pumping as necessary. <br />L J <br />(i) General Drainage Plan <br />(i)(A) Sediment ponds B, C, J & K and the general drainage plan for the main site <br />and loadout were prepared under the direction of J. E. Stover, Colorado <br />Professional Engineer, No. 19230. Sediment pond D and the general <br />drainage plan for the gob pile was prepared under the direction of Allan J. <br />Breitenbach, Colorado Professional Engineer, No. 15247. <br />(i)(B) A description of the ponds is presented above. Detail drawings of ponds B, <br />C, J & K are presented on Map Nos. 22-B, 22-C, 22-J and 22-K respectively. <br />A detailed drawing of the gob pile sediment pond is presented in Volume 4, <br />drawing 95266-04. <br />(i)(C) The preliminary hydrologic and geologic information required to assess the <br />hydrologic impact of the structure is presented in Volume III, Exhibit 8 for <br />ponds B, C, J & K and Volume IV, Appendices A and B for the refuse pile <br />pond. <br />(i)(D) No underground mining has occurred under any of the sediment ponds and <br />none is anticipated. <br />(i)(E) Not applicable. <br />(ii) Detailed Design Plans <br />(ii)(A) Sediment ponds B, C, J and K and the drainage plan for the main site and <br />loadout were prepared under the direction of J. E. Stover, Colorado <br />Professional Engineer, No. 19230. Sediment pond D and the drainage plan <br />for the gob pile was prepared under the direction of Allan J.
