CA::YO:d <br />SZTF. FOR llSE AS A IJaSTL• DISPOSAL SITE. <br />Salt Creek Mining Company has submitted an anal;~sis of the coal to be mined. <br />These data indicate the presence of so a ele~aents at higher than normal <br />levels. The Division has determined. that there is a very slight possibility <br />that adverse effects to the environaent will result due to exposure of the <br />coal in a surge pile on the mine be::ch. There are several reasons for <br />this determination. _ <br />The coal in the surge pile will be-exposed to surface runoff for short periods <br />of tine. ?laterial in the pile will nor_nally be cycled within one day. There <br />is therefore little potential for excessive leachin3 bf material in the pile. <br />The area of the surge pile accounts for only 3.5 percent of the total disturbed <br />area. This is approxi.matelp the ratio of contribution of leachate from the <br />surge pile to rye runoff from the rest of the disturbed area. The leachate <br />would be appreciably diluted in this case. <br />All runoff from the surge pile and the bench area is contained with a <br />sediaent control system as described i.n the folloving-section (V. Hydrelog'_c <br />Balance: Surface Water) of this docu:ent. The system will prevent the <br />runoff from entering the natural drainege. Runoff frog the area will be <br />released into the natural drainage only after it meets all applicable <br />effluent standards. <br />The information provided dealing with surface water quality, surface water <br />quantity and sedimentation control was reviewed by the Division. This <br />infornation can be found in Sections 2.4, 4.2.6, and 4.2.7 of Volume I and <br />Appendix Af of Volume IV of the application. The following comments are <br />based on review of these materials. <br />The applicant has supplied surface water quality data which is specifically <br />required by Rule 2.04.7(2)(b)(ii). The analyses provided (Tables 4.2-6 and <br />4.2-7 and Figures 4.2-8 and 4.2-9) include a number of parameters in <br />addition to chose required by the Rules and Regulations. Data provided by <br />the applicant are sufficient to make the required findings of compliance <br />for this section. <br />These data indicate that the baseline water is substandard in quality - <br />(according to Mined Land Reclamation standards of august 26, 1981). The <br />operation will have little effect on [he quality of this water. The <br />Division requires that monitoring of surface water continue during mining <br />to verify these conclusions. The following discussion e_eplains the <br />monitoring program. <br />Sur_'ace water euantit:~ and quality till be monitored upstream and dq rstrear.. <br />of the disturbance in ?1cClane Canyon and on East Salt Creek upstream and <br />de:•nstream of the confluence of ?IcClane Canyon and East Salt Creek. Salt <br />Creek ?fininb Connany has agreed to establish a neu monitoring site on East <br />Salt Creeic directly below the mouth of ?ScClane Canven. The Division <br />
