• Mulching Techniques <br />As stated earlier, a straw mulch consisting of a native grass hay will <br />be used. The planned application of the mulch will be a minimum of <br />2,000 pounds per acre on flat areas and 4,000 pounds per acre on steeper <br />slopes. <br />Irrigation <br />No irrigation is planned for the areas to be seeded or mulched. If <br />climatic conditions such as severe drought dictate that irrigation must <br />be used at some future date, a detailed irrigation plan will be <br />submitted to the Division for approval prior to the implementation of <br />any irrigation program. <br />Pest and Disease Control <br />• Noxious plants as defined in Section 1.04 will be controlled using <br />recommended methodologies of the Colorado State University Extension <br />Service. If outbreaks of insects become a problem to the point they <br />endanger the successful establishment of the seeded vegetation on the <br />reclaimed area, they will also be controlled using methods suggested by <br />the Colorado State University Extention Service. All herbicides and <br />pesticides utilized will be those that are approved by the appropriate <br />Colorado and federal government agencies responsible for the approval <br />and distribution of such agents. <br />Measures for Determining Success of Revegetation <br />Because the area has been previously disturbed by past underground <br />operations, the success of reclamation at the planned surface facilities <br />and portal entries will be determined as explained in Section 4.15.10. <br /> <br />2.05-35 <br />
