PAR - C-80-007 - 5 - March 31, 1986 <br />predictions. The chemistry of the adit waters should be discussed <br />and graphically presented to show major ion chemistry, levels of <br />trace elements and other characteristics of importance. This <br />information is needed in order to evaluate impacts from springs or <br />seeps from the mine after closure. <br />12. The application for renewal contains hydrology data up to year <br />1981. Subsequent monitoring data conducted from 1981-85 needs to <br />be incorporated into the application so that it may be reviewed and <br />evaluated by the Division and the public. Important monitoring <br />sites such as mine inflows, mine discharge, selected streams and <br />springs need to be summarized and graphically presented using <br />charts, graphs, or other figures. Water quantity, ion chemistry, <br />and other important characteristics need to be discussed and <br />summarized. Much of this information is included in separate <br />annual hydrologic reports (AHR's) but needs to be consolidated and <br />presented as a whole and made part of the record by incorporation <br />into the application. <br />13. Provide a list, according to watershed, of all springs and seeps <br />that have been undermined to date, that will be undermined during <br />the reviewed permit period, and that will be undermined during the <br />remainder of the mining period. The list should include the depth <br />of overburden between the spring/seep and the coal seam to be <br />mined. Also provide a interpretation of which springs/seeps will <br />be significantly impacted by mining and quantify what the impact <br />will be to the surrounding watershed. <br />14. Provide a mine subsidence map for the next 5 year permit period <br />which shows the area (including angle of draw) to be subsided along <br />with approximate dates. <br />15. Provide a list <br />watershed, and <br />along with act <br />past 6 years. <br />situations are <br />interest. <br />of all flumes, weirs, and gages, according to <br />include information on their size and flow range <br />gal seasonal values of flows experienced over the <br />This information will ensure that monitoring <br />adequate to accurately measure flow ranges of <br />16. Page 2-372 of the permit application states...Minnesota Reservoir <br />appears to have an effect on the water quality characteristics of <br />Dry Fork. This statement should be expanded. Quantify and provide <br />an interpretation of any affects Minnesota Reservoir may have on <br />the water quality of Dry Fork. <br />17. Provide a table(s) for all gaged watersheds listing the monthly <br />average, minimum, and maximum flows, the peak flow and base flow <br />per year, and the low flow (Q7, 10) for years 1980-1985 for the <br />following: Sylvester Gulch, Upper Dry Fork, Lower Dry Fork, Lick <br />Creek „Snuth-Prong, Ho k, and East Fork Minnesota Creek. <br />Also, classify each stream to either perennial, ephemeral, or <br />intermittent, and include drainage basin area.
