Include as part of the reclamation plan the type and amount of fertilizer to be used for revegetation per Rule 6.4.5(f)(iii). Response: The seed mix for final reclamation as described in Exhibit E does not require fertilizer as recommended by the local NRCS office in Greeley, Colorado. The seed mix was revised slightly per the NRCS's latest recommendations that require less seed to be drilled or broadcast per acre of disturbed area.

If seed is to be broadcast, the application rate will be doubled. The seed mix application rates were recommended by the local NRCS office in Greeley, Colorado. Please refer to the revised Exhibit E and the attached letter from the NRCS. 22. The reclamation plan calls for covering the seeded areas with straw mulch at a rate of 2,000 pounds per acre. The Division recommends using 4,000 pounds per acre. Response: The rate for straw mulch application was revised to 4,000 pounds per acre. Please refer to the revised Exhibit E. 23. The reclamation plan states that inlet and outlet facilities for the reservoir will be designed when the end use of the reservoir is identified. Please provide the Division with the general location of these structures and identify them on the reclamation plan map. If the location of these structures needs to be changed, it can be done by submitting a technical revision to the Division. Response: The general location for the inlet/outlet facility has been shown on the reclamation plan map and described in the reclamation plan. We anticipate that the structure will function as an inlet and outlet as it will be a wet well with a pump station. The wet well will accept incoming flows that will fill the reservoir. The incoming flow will enter the top of the wet well and exit through an inlet/outlet pipe that is placed at the bottom of the wet well and extends out into the reservoir on the bottom of the 20 1400 W 122nd Avenue - Suite 120 • Westminster CO 80234 • Ph: 303-457-0735 • Fax: 303-920-0343
