Mr. Gregg Sguire May 1, 1000 Page 3 oj4 Comment 10 The maps in Exhibit C and Exhibit F have been corrected to illustrate that mining will not extend beyond the permit boundary. The revised Exhibit C and Exhibit F plan maps aze presented in Attachment D. Response to Mr. Cregg Squire Comments Submitted ou April 20, 2000: Comment I • The applicant plans to use the SCS seeding recommendation. • The applicant will plant trees and shrubs in areas where tree/shrub clusters are illustrated on Exhibit F. The tree and shrub species will be selected from the lists provided in Exhibit E, with no one species being more than 25 percent of the total species planted. The applicant hesitates to commit at this time to the exact species to be used. Availability and associated costs of specific trees and shrubs at the time of planting may make such a commitment unpractical. • The applicant is committed to planting 50 trees and 50 shrubs around the easUsoutheast side of Lake 1 and 30 trees and 30 shrubs around the north side of Lake 2. The success standard used will be 80% survival at the time of bond release. Comment II • The applicant does not anticipate that the lined reservoirs will affect alluvial ground water elevations up or down gradient of the site. However, to detect and mitigate potential impacts to the alluvial ground water elevation due to mining operations or reclamation activities, the applicant will monitor ground water levels. Eight (8) monitoring wells will be installed around the perimeter of the site to obtain baseline data and monitor ground water levels during mining operations and reclamation activities. The locations of the proposed monitoring wells aze illustrated in a revised pre- mining/mining plan map provided in Attachment D. To provide timely and representative ground water elevation information, the eight (8) new monitoring wells will be completed, developed, and surveyed immediately upon permit approval. Well coordinates and top of casing (measuring point) elevation data will be collected upon well completion. Well coordinates, measuring point elevations, and water level measurements will be made to the nearest tenth of a foot. Ground water level measurements will be taken on a monthly basis starting at a minimum of 3 months prior to exposure of ground water at the site and will continue throughout the mine operation and reclamation activities. Data collected prior to mining below the ground water table will be used to establish baseline ground water elevations for the site. Baseline elevations will be established fora 12-month period. If an entire yeaz of ground water monitoring cannot be completed before exposing ground water at the site, data collected at the site will be used with documented regional ground water data to extrapolate baseline ground water elevations for the entire 12-month period. The ground water data will be submitted to the Division along with other annual reporting requirements.
