The Division received your responses to those <br />questions on December 1, 2017. The Division reviewed the responses and has the following question: <br /> <br />Section 2.05.4(2)(d) <br />Item resolved. <br /> <br />Section 2.05.4(2)(e) <br />Tri-State is proposing to use “the current year annual alfalfa yield for Montrose County” as the basis for <br />the success criterion for the Garvey Property irrigated pasture. The data will be obtained from the <br />USDA – National Agricultural Statistics Service. The success standard proposed by Tri-State is <br />adequate. Although, it must be noted that the ‘current year annual alfalfa yield’ is published by the <br />USDA in November of the year following any production sampling at the mine site. By using the <br />current year data as the reclamation standard, all future bond release applications will be delayed about <br />1 year waiting for the appropriate data to be published. Does Tri-State want to commit to this timeline <br />for this standard? <br /> <br /> <br />If you have any questions or need additional information, please contact me at (303) 866-3567 ext. 8142. <br /> <br />Sincerely, <br /> <br />Brock Bowles <br />Environmental Protection Specialist <br />brock.bowles@state.co.us <br />December 5, 2017 <br /> <br />Chris Gilbreath <br />Tri-State Generation and Transmission Association <br />12050 North Pecos St. Suite 100 <br />Westminster, CO 80234 <br /> <br /> <br />
