There are no provisions for revegetation of the 7 acres of wetlands benches. Although a U.S. <br />Army Corps of Engineers 404 Dredge & Fill Permit may not be needed for created wetlands, the <br />applicant will still need to provide the Division with a revegetation plan for the created wetlands <br />and itemized costs for backfilling & grading as well as revegetation of such azeas. (If the <br />applicant is planning on 100% volunteer growth of wetland vegetation, the Division will still <br />require a contingency plan and cost for seeding). <br />I N'1i~ <br />12.

Because of the location of the proposed slurry wall, there may be a slight alteration of the <br />existing surface and groundwater drainage pattern (recharge/dischazge) in the cottonwood grove <br />between the South Platte River and Ponds A & B. Therefore, the potential exists for adverse <br />impacts to the mature cottonwoods at several or more times throughout the year. Accordingly, <br />the Division requests that the applicant provide additional details of the monitoring and <br />mitigation to be done to minimize possible impacts to the cottonwoods throughout mining and <br />reclamation. Specifically, what parameters will be monitored, what is the frequency of <br />monitoring, will results be reported to the Division and at what frequency, what are the specific <br />"triggers" that will define when the trees are being stressed, and how long will supplemental <br />irrigation water or groundwater from the pits be applied in the event of a possible impact. <br />EXHIBIT G -WATER INFORMATION <br />~1 14. Both the Existing Conditions Map and Mining Plan Map show the locations of 10 existing <br />~ monitoring wells. Please explain the type & configuration of the wells and nature of any on- <br />going or proposed monitoring program. `~ ~ /, J,`~^ ~r 1 7 <br />~> <br />
