Rule 4 Performance Standards: Please explain the rationale for removing the text on page 4-11 related <br /> to pit pumping. <br /> 2. Rule 4 Performance Standards: Please explain the rationale for removing the text on page 4-12 related <br /> to the French drain. <br /> 3. In the original submittal,the SEDCAD model for the 100-year runoff into the ponds does not include <br /> most of the undisturbed areas along the east side of the watershed. Subsequently,an updated <br /> SEDCAD report was provided by the operator. No additional response is required. <br /> 4. The Division has performed a reclamation cost estimate to reclaim the addition of Upper and Lower <br /> Section 3 Ponds including pond maintenance over the ten year liability time period. The total value of <br /> this estimate is$95,851.00(see attached cost estimate).The Division's cost estimate is consistent with <br /> previous cost estimates approved by both the Division and Colowyo.The Division respectfully requests a <br /> response from Colowyo with any questions regarding the cost estimate or an acceptance of the Division's <br /> estimate. <br /> If you have any questions,feel free to contact me. <br /> Sincerely, <br /> flF'�010 <br /> 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br /> Jared S.
