Please include your response to this comment with your responses to the preliminary adequacy <br />review. <br />ADEQUACY ISSUES <br />Exhibit E -Reclamation Plan <br />The proposed seed mix consists entirely of grasses (and one grain), most of which are not suited <br />to the dry climate and poor, saline soils found at this proposed site. It also includes winter wheat <br />as a nurse crop. Please revise the seed mix so it includes a few saline, drought tolerant grass <br />species mixed with seed from a few of the native shrub species found in this area such as black <br />greasewood, four-wing saltbush, rubber rabbitbrush, broom snakeweed, and big sagebrush. Use <br />of a nurse crop is not recommended in arid country due to the competition for moisture. Also, <br />please specify the estimated availability of proposed seed as required by Rule 6.4.5(2)(d). <br />If you need additional information, please contact me at the Division of Minerals and Geology, Grand <br />Junction Field Office, 101 South Third Street, Room 301, Grand Junction, Colorado 81501, telephone no. <br />970-243-6368. <br />Sincerely, <br />-'~~~~ <br />Steve S.
