<br />Mulching Techniques. A mulch consisting of prairie hay obtained <br />locally or clean cereal grain straw will be used. The application <br />of this mulch at a rate of approximately two tons per acre will be <br />accomplished by hand placing or blowing the mulch on the regraded <br />and scarified surface. To supplement the mulch in an effort to <br />minimize erosion potential, contour furrows will be placed along <br />the contour immediately after mulching and seeding has been completed. <br />These contour furrows will help to minimize sheet erosion which may <br />result along these fairly steep long slopes. At any rate, rills <br />and gullies will be minimized. <br />Irrigation. GEC Minerals, Inc. does not currently use or plan to <br />use irrigation to supplement the revegetation effort on its recla- <br />mation projects. However, if severe drought in the future dictates <br />that revegetation cannot be accomplished without irrigation <br />measures, GEC Minerals will submit a detailed irrigation plan for <br />• approval by the Colorado Mined Land Reclamation Division prior to <br />the implementation of any irrigation program. <br />Pest and Disease Control. GEC Minerals, Inc. plans to utilize <br />methodologies described and recommended by the Colorado State <br />University Extension Service for controlling noxious plants. If <br />severe problems result from insects that will endanger the success- <br />ful establishment of new vegetation on the reclaimed area they will <br />also be controlled using methods suggested by the Colorado State <br />University Extension Service. Herbicides and pesticides which will <br />be utilized will be approved by the appropriate State and Federal <br />governmental agencies prior to their use. <br />Measures For Determining Success Of Revegetation. Each year the <br />reclamation area will be investigated to determine its productivity, <br />diversity and cover as described in Section 2.04.1. Data from this <br />investigation will determine the success of the revegetation <br />effort. Techniques will be similar to those used by the Soil Conserv- <br />• ation Service within this area and will also meet the Performance <br />Standards of the Rules and Regulations as to methodology and statistical <br />confidence. <br />2.05-29 <br />
