<br /> <br /> 18 <br /> A. Water Quality Standards and Effluent Limitations <br /> <br />The Division proposes to re-approve a small area exemption from use of sediment <br />ponds due to the limited size of the area and due to the fact that ponds and treatment <br />facilities are not necessary to treat the runoff from this area to meet the effluent <br />limitations of Rule 4.05.2 and applicable State and Federal water quality standards for <br />receiving streams and also due to the fact that no mixing of surface drainage with a <br />discharge from any underground workings will occur. The small area to be exempted <br />is Topsoil Stockpile #2, located along the railroad spur between Reed Wash and the <br />Loma Drain. It is referred to as SAE #1 and the SEDCAD demonstration of <br />compliance with effluent limitations can be found in Appendix 9 (4.05.2(3)(b)(i)). <br /> <br /> B. Diversions and Conveyance of Overland Flow <br /> <br /> 1. The Division does not propose to approve the use of asphalt, concrete, or other <br />similar material to line a permanent diversion (4.05.3(3)). <br /> <br /> 2. The Division does not propose to approve construction of a diversion on an <br />existing landslide (4.05.3(5)). <br /> <br /> C. Stream Channel Diversions <br /> <br /> 1. The Division does not propose to approve the diversion of an ephemeral stream <br />draining at least one square mile, an intermittent stream or a perennial stream <br />(4.05.4(1) and (4)). <br /> <br /> 2. Channel lining structures and artificial channel roughness structures are proposed <br />for use to control erosion. These means are proposed to be approved by the <br />Division since they are necessary to control erosion, they are stable and will <br />require infrequent maintenance (4.05.4(2)(a)). <br /> <br /> D. Sedimentation Ponds <br /> <br /> 1. The Division does not propose to approve the location of a sediment pond in a <br />perennial stream (4.05.6(1)(b)). <br /> <br /> 2. The Division does not propose to approve the submittal of reports required by Rule <br />4.05.9(17) on other than a quarterly basis. At this time, no sedimentation ponds <br />have been constructed at the loadout. <br />
