SUITE 305 7Ht~tiON COLOPADO 80233 ~,'`\ 1`•`.~~ 450-2204 FFB ~~ Og 199S D~~isiQn o~ ~n~ra/S & ~~o logy I reviewed your January 23, 1995 letter and the subsequent faxed map you sent with Cooley. Cooley would like to propose the following, with the numbers corresponding to those in your letter: 1. The line you outlined on the FAXED map is OK, but only as a temporary exclusion area until UD&FCD plans are completed. This area will be disturbed by the UD&FCD channel improvements, specifically the rip-rap trench and grade control structure. The accompanying map, from the agreement with UD&FCD and Cooley, shows conceptually these improvements. It was always the intent to install these improvements wherever UD&FCD determined they should be located, and then install the slurry wall behind (to the south and east) of the riprap trench. The reason that Cooley agreed to double the amount of trees along the River was to replace those in this area that will be destroyed by these actions. My note on the map already made this a temporary non-disturbance area until UD&FCD plans are finalized. Cooley is willing to change the map to reflect this temporary exclusion area as the area you marked on *_he map ycu FAXED me. This map would then be submitted in the revised booklet incorporating all changes from the original application, after the approval is granted. Cooley is also willing to make it clear that no mining will occur north and west of the eventual location of the riprap trenches, and I have changed two pages of EXHIBIT D (Mining Plan Narrative) to make this clear. 2. Your statement on ground cover is acceptable, as it relates to areas north and west of where the riprap trench and slurry wall would eventually be installed. Item 4 of the EXHIBIT E - RECLAMATION PLAN NARRATIVE has been revised appropriately and is attached. This revised narrative portion of the exhibit will also be included in a revised booklet incorporating all the changes from the original application, after the approval is granted.
