V. Chemical parameters that should be addressed especially <br /> during high flow regimes are: <br /> 1. TSS <br /> Total suspended solids in Coal Basin range from 0 to <br /> 3 or 4000 PPM. Various natural streams (undeveloped; Bear Creek, <br /> Disney Creek and Sutey Creek) have similar ranges. Dutch Creek <br /> shows sign of elevated TSS that probably can be directly attributed <br /> to the main truck haul roads. Sutey and Disney Creek both have <br /> an average annual TSS level below Dutch Creek but Dutch Creek <br /> has higher spring melt numbers. We believe that a major portion <br /> of the sediment comes from the hill truck traffic that will be <br /> eliminated by the end of 1986. <br /> 2 . Iron concentration - (a trend has been identified where <br /> iron concentrations are high during spring runoff events) <br /> VI. During review of the water quality description and Probable <br /> Hydrologic Consequences of Mining in the permit application, it <br /> was noted that no mention has been made of the potential for coal <br /> fines generation during spring runoff due to the melt of snow <br /> layered with air carried particulates emitted principally from <br /> the thermal dryers. The Division realizes that this contribution <br /> is not quantifiable but surely leads to an increase in dissolved <br /> and suspended constituents in spring runoff. A description of <br /> any impacts possible from the thermal dryers - by air carried <br /> particulates should be included in the PHC. Also, if any analyses <br /> are available of the quality or quantity of emission from the <br /> thermal dryer this should be included within the water quality <br /> description. <br /> 1. Air Quality - Thermal Dryer <br /> Enclosed is a description of the thermal dryers and how <br /> they operate (1978) . Also enclosed is a total fugitive dust <br /> estimate done for the Department of Health in 1980. I am not <br /> sure how accurate these are but at the time I passed them by <br /> Scott Miller (area Air Pollution Engineer C.D.H. ) and he said <br /> that they were in the ball park. <br /> A large portion of the particulates and I think by far <br /> the majority, fall in to areas covered by sediment control systems. <br /> The remainder would fall directly adjacent to Coal Creek and be <br /> washed in to the stream. It would not matter if this happened on <br /> a given day or was a six month' s winter accumulation the end <br /> result would show up in the spring runoff water quality samples . <br /> In the past, water samples were taken monthly and in some cases <br /> twice monthly. Any readily detectable excess amount of sediment <br /> or other constituents would show up, as all of the sampling <br /> stations can and have been compared with several nonimpacted <br /> streams (Porcupine, Sutey, Bear, Spring and Braderich Creeks) . <br /> What ever the amount, it obviously would show up, as the accumu- <br /> lation from 1956 to 1986 would surely be detectible, if it was <br /> significant. <br />
