<br />lv. Geology - kules [.04.6 and Z.U4.6(1; <br />Pules "L. U4.6(1)(C)(U} and (Ej require physical and chemical analyses o. <br />' eacn overourderi and interburaen stratum and the stratum irti~ediately oelow <br />the lowest coal sewn to oe mined and chemical analyses of each coal seam <br />in order to identify potentially toxic forming horizons whicn might <br />' ~/ impact revedetation or surface or ground water quality, and necessitate <br />spe;.ial handliri;. <br />Tne overourden analyses in the application are limited to composite <br />samples from one exposed pit wall. Cnemical and physical (textural) <br />analyses must be provided for each stratum down to and including the <br />lowest coal seam to be mined. The analyses should be performed on the <br />' core material from at least one representative drill hole in the area to <br />be disturbed at Pit 4 and at Pits 7 and 8. <br />' The analyses must include all of the parameters indicated in Attachment 1 <br />of this letter. <br />Rule 2.04.7 - Surface dater Baseline <br />1. The application does not contain a spring and seep. survey. The <br />applicant should provide a map showing the location of all spring <br />and seeps in the permit and adjacent area. In addition, as <br />required under rule 2.04.7(2)(a), the applicant should provide <br />' sufficient baseline infonnation to identify the seasonal . <br />variations in water quality and quantity for the springs: <br />2. The applicant has indicated that mining operations could affect <br />water quality in Grassy Creek (p. II. F-3). Water percolating <br />through the mined area would discharge as springs and seeps in the <br />' Grassy Creek drainage. This discharge would_:raise the <br />concentration of total dissolved solids in Grassy Creek. The <br />applicant should provide a quantitative estimate of this effect on <br />the Grassy Creex stream/alluvial aquifer system under normal <br />seasonal fluctuations. In addition, the applicant should identify <br />downstream water users that could be affected, and propose <br />mitigations, if appropriate. <br />.,. ind applicant ir,u~cates that the oaseline surface water monito n n_ <br />' proyram would uc reduced following the collection of one year'; <br />data. Utner aspects of the operation's surface and grounu water <br />monitoriny are not discussed. The applicant should provide a plar <br />for the Collection, recording, and reporting of ground ano surface <br />' water quality znd quantity data during operations ana <br />reclamation. Tne plan should include surface water monitoring on <br />Grassy Creek, alluvial ground water monitoring, monitoring pond <br />' discharges, ane the monitoring of spring flow ana spoil water, if <br />appropriate. <br /> <br /> <br />
