<br /> <br />in No Name, Hast Buzzard, Coyote, West Buzzard, Middle Pyeatt, and <br />Haet Pyeatt drainages due to pit dewatering. No specific approvals <br />are required by the Division under this section. <br />B. Stream Channel Diversions <br />Drainageway reconstruction ie discussed under Section 4.8.1.3, <br />Vol. IV of the permit application. <br />Channel lining structures, retention basins, and artificial <br />channel roughness structures are proposed for use to control <br />erosion. These means are proposed to be approved by the <br />Division since they are necessary to control erosion, they are <br />stable and will require infrequent maintenance. The applicant <br />uses rock check structures, various geotextiles, and rapid <br />growing vegetation within reconstructed drainages to control <br />erosion. (4 .05.4(2)(a)). <br />Sedimentation Ponds <br />Sediment ponds are discussed under Section 4.8.1.4, Vol. IV of the <br />permit application. <br />The applicant uses sedimentation ponds in all disturbed drainages <br />to control the increased sediment loads within the ephemeral <br />drainages on the mine site. All sediment ponds are designed to <br />contain or treat the 10-year, 24-hour event and safely pass the <br />25-year, 24-hour event, at a minimum. One MSHA size pond exists <br />on the Bite in the Coyote drainage, but as of 1992, this pond is <br />usually dry. <br />D. Surface and Ground water Monitoring <br />The applicant will conduct monitoring of ground water in a <br />manner approved by the Division. The ground water monitoring <br />plan can be found in the permit application on pages 4-247b to <br />4-247c and page 4-241c, as well as Section 4.8.5.2a, Vol. IV. <br />(4.05.13(1)). <br />The applicant will conduct monitoring of surface water in a <br />manner approved by the Division. The monitoring plan was <br />submitted under 2.05.6(3)(b)(iv) and can be found in the <br />permit application on pages 4-241b to 4-241c as well ae <br />Section 4.B.S.la, Vol. IV. (4.05.13(2)). <br />The Division has reviewed the surface and ground water monitoring <br />plans ae part of the revision process. These monitoring plane are <br />adequate to monitor for the development of impacts, if any should <br />develop. <br />IV. ToDSOil <br />Soil information can be found in Section 2.6, Vol II and Section 4.9, <br />Vol. IV. <br />The Division is proposing to grant a variance from topsoil removal <br />in accordance with Rule 4.06.2(2)(a). Specific areas which the <br />operator will not strip topsoil are limited to rocky areas which <br />occur over limited areas throughout the mine area. Each area <br />approved is handled separately as a minor revision to the permit <br />and no general variance ie currently approved. <br />Page 17 <br />
