-25- • the total area disturbance is so small ,, the potential cu•rulative effect of the operations on surface water quantity is also negligible. Approximately 8.4 acres in Hunger Canyon and 3 acres in ~~fcClane Canyon will be contained within sedimentation systems. This accounts for aparoximately .02 percent of the drainage area of East Salt Creek above the confluence of Munger Canyon. Obviously, the impact of the operations on sur?ace water quantity in East Salt Creek will be negligible. The impact on water quantity :+i11 also be minimal since water retained by the structures wi1Z be discharged following settlement of suspended solids. As mentioned previously, no wells or springs have been identified in ~4cCZ ape or dfunger Canyons. No ground water rights have been adjudicated wi thin a three .mi.1e radius of the mines. Neither operation will have an effect on any major aquifers. Drilling in and around the ,7cClane and Munger permit areas indicates that the mine zone will be dry. No ground water inflows are anticipated far either operation. There will be no need for discharge of mine water from either mine. A saturated zone has been identified in the Cameo coal seam (Figure 4.4-1). The proposed mine plan indicates that this zone will only be encountered by the McClave Canyon mine workings around the eleventh year of operation. Ground water inflows into this :nine wi/1 be monitored throughout the term of operation so the zcne can be identified further and impacts can be projected. i• The mine workings will acproach the Cameo subcrop in Sast Salt Creek in years eleven to fifteen of the ,+inger Canyon operation (see Figure 2.1-41. Prior to this, Salt Creek Mining Company will be required to submit an application to allow the extension of the mine. At that time, sufficient data :+i11 be available to assess the potential for an effect on East Sait Creek tributary ground water. The effect of underground mine workings in Stave and Bunigez Canyons on the quality and quantity of surface water in dig Salt :Dash is expected to be negligible. No surface disturbances are anticipated in these canyons so there is no potential for impacting water quality (see Section vI7, A11av+'a1 valley Floors, of this document). .There is a potential for surface water infiltraticn into the mine workings via natural and mine-induced fractures. This potential is very low due to the low precipitation experienced by the region and because of the steep slopes over the nine :+orkings.
