Therefore. Salt Creek is only modifying the means by which the water is discharged and no significant harm is being done to the local hydrologic regime. If coal production at the mine resumes during the next year the only chance to the effect upon the aquifer will be an increase in the quantity of water that is discharged from the mine. Salt creek will use some of the water generated at the mine but compared to the total available water in the East Salt Creek regime the effect will be insignificant. Additionally. since there are no known water rights adjudicated for this aquifer, there is little chance that water interests are being injured. HUNGER CANYON M[NE To date there has been no water encountered by this mine: therefore. there has been no effect on the hydrologic regime of the area. Table 2 documents that there has been no water used at Munger. Since there has been no mining at either mine the mine workings mans included in the last submittal are still correct and should be retained. EFFECT OF THE MINES ON THE EAST SALT CREEK REGIME Surface Water Due to the limited disturbance of the mines there is little chance tnat any significant effect on the quantity or quality of the surface waters near either mine sites has occurred. As the Division notes in its approval package for the Munger Canyon Mine. the total area tYiat will be disturbed by both mine sites amounts to 0.12 percent of the area of the East Salt Creek drainage bas(n above the mines. Surface water samples are only being taken at one location on both McClane Creek (SW-2) and Munger Creek (SW-3), because Salt Creek has been allowed to alter the approved monitoring program. The alteration was requested in March of L984 because there was little activity at the mines and reduced sampling was adequate to determine the effects of mining on the environment. Results of the quarterly sampling for each monitoring site are shown on Table 2. The results of water sampling at SW-3 in Munger Creek are highly variable as was the case with the baseline data. Although sample site SW-2 was Checked numerous times during the reporting period, no flow was realized. It should be noted that most of the time sampling was attempted during rainstorms. The nature of the McClane Canyon is that it takes an intense storm to cause the creek to run. Many timed these events occur late at night or at other times when employees are not Present. Hopefully. the proposed relocation of the Salt Creek offices to the McClane Canyon Mine will allow better monitoring of flow conditions in the creek. Page - 3 ll/16/88
