RE: File number 81-293. Pit No. 2. Crow Creek, at this site, is relatively undefined being a depression of only two to three feet deep for the approximate width shown on Exhibit C. The depres- sion forming the drainage way consists of relatively flat sided slopes of about 10 feet horizontally to one foot vertically. These slopes will be maintained and replaced. During actual mining operations, any drainage in the creek will be diverted by mounds adjacent to excavated areas equal in height (2' to 3') to the difference in elevation from adjacent land to the bottom of the creek. Bank stability at each site will be provided by reclamation and seeding processes as shown in the Soil Conservation Service recommendations. The County will rehabili- tate the area and slopes of finished area in like manner to all adjacent surface areas as stated in the Application for each site. All stockpiles, if used, will be located parallel to and as far from the banks of trie creeks and within the permitted area. The County's operation does not consist of stockpiling at either Pit No. 2 or Pit No. 3. The material is removed directly from the pit to trucks as needed thereby eliminating need for stockpiles. The County is unaware of the existence of any cottonwood trees at any of the sites. Topsoil salvage, where topsoil exists, will occur on all disturbed areas of each site. See detail to be followed as recommended by the Soil Conservation Service letter included as an Exhibit with each Agplication. 7. Proof of publication and notification will follow. Local approval for File number 81-287 was obtained on January 19, 1981 from the Weld County Planning Commission. Documentation will be forwarded when recieved by this office. If you have any questions please contact me. Sincerely, ~ Drew L. Scheltinga Acting Director of Engineering DLS:sc
