. ~. One well is of particular concern. The property located directly to the south of the proposed site is irrigated using a large capacity irrigation well, Permit No. R-15750-RF, which feeds a center pivot pond. Well No. R-15750-RF and the center pivot pond are located within 300 feet of the proposed mining area. As such, dewatering activities at the proposed mine site would have a profound impact on this well, and could affect the center pivot holding pond. Mayer Farms has hired a water engineer to assess the magnitude of harm likely to be caused by dewatering, and I will provide the Division with the engineering report as soon as it is available. As the 112 application stands, the applicant has failed to carry its burden in demonstrating that impacts on the prevailing hydrology will be minimized, and the Division should recommend denial of the application for this reason. In addition to Well No. R-15750-RF, there are also a number of large windbreak trees located on the north side of the Mayer property, directly south of the proposed mine site. These trees depend upon ground water, and the lowering of the water table via dewatering could injure or kill these trees. Mayer Family Farm has several other concerns with the application as filed. The soils on the subject property is sandy, and prone to both wind and water erosion. See 34-32.5- 116(4)Q), C.R.S. As such, the 3:1 slope proposed for the final grade of the pits is too steep, at least for such time as the slopes are exposed to wind and running water. In addition, revegetation efforts will have to be tailored to accommodate the land's tendency to "blow," and the bond should be sufficient to allow several attempts at revegetation. Flora species should be selected that have a reasonable chance of becoming established in the sandy soil. Mayer Family Farm will continue to study the application and may submit additional comments. As of late, I have not been receiving copies of all materials mailed to the parties to 112 applications. Often, my clients are copied, but I am not. Please send me copies of all materials mailed to any party. Thank you for your attention to this matter. Sincerely, LI LAWRENCE & OTTENHOFF, LLP .
