The applicants treau;ient of mine inflows ~.viChin the permit applicatio;; <br />deals with an estimate of mine infl„vs made in a 190 study. This study <br />clealUr only •wiLn the IJo. 5 mine, and dealt wiCh the Plo. 9 mime ;.hrouyh <br />extrapolation. Given the length of time between this sturJy and the <br />present; given the amount of mining :which has taken place since 193u; and <br />given the requirements in kule 2.U5.7(3)(a), and 4.U5.13(1)(a) to monitor <br />the hydrologic impacts of ~nininy during operation; the applicant shall <br />verify the results of the study with a new mine inflow study ~•;hich <br />includes uoth the P;o. 5 and Igo. 9 niir~es. This inflow study shall include <br />the ~uappiny of all mine inflows presently encountereu in both ~uines on a <br />recent mine workinys maps. Httachn~ent Q contains an example of an inflow <br />study conducted uy another underground mine in the state. The inflow <br />study shall include a table keyed to the map whicn includes the following: <br />(a). 11ow rates (OSllinates ul luw inflow l'aic'., .uul ~nca,urc•m;iil.•, ul <br />flows in excess of one gallon per minuC~); <br />(d). Sources of each inflow (i.e. fauTi., fracture, roof bolt, seal <br />from an abandoned-pillared area, abandoned bore hole, weeping <br />wall face, or reof, etc). <br />(c). Geologic source of each iufloo-,. , <br />(d). Total area contributing to each inflow (e.g. abandoned-pillared <br />area of mine 20 acres; coal face 6 ft. high and 250r`t. long; <br />paint source bore hole, etc.); and <br />(a). Field water quality incluuing pH, electro-conductivity acd <br />temperature. <br />Tne applicant shall recalculate the projected inflows for all minim in <br />tnis 5-year permit period in both mines. Tlie projections shall b2 made <br />~~ith data gathered in the new inflow study outlined above. This will <br />require amine plan delineating areas of complete extraction (projected <br />subsidence areas), partial extraction (entries and subsidence protection <br />zones), and projected faults and fractures. The applicant shall also <br />calculate the quantity of water required to fill the mine workinys to <br />pre-existing water levels and the time required to fill the ~•.or!:ir,gs for <br />the combined 5-year and pre-existing workinys, and also 'for the total <br />life-of-mine workings. <br />The annual Hydrologic report shall include a yearly submittal of an inflow <br />study as outlined .:hove. The amwal mine influw sturJy shall also include <br />a. record of daily discharges from each of the mines. <br />
