Streamflow- Normally, the limited natural runoff from this area (estimated at 200 acrefeet <br />per square mile per yeaz for water rights purposes) does not reach the North Fork except <br />during high snowmelt or rainfall-runoff periods (when there is no "call" for water in the <br />river). Furthermore, as discussed in Section 2.05.6 (3)(b)(iii & viii), Streams, surface flow <br />losses will be small. A conservative projection of the average annual streamflow"lost" to <br />crack infiltration in the North Fork drainage is less than one acre-foot. The losses that do <br />occur (as a consequence of infiltration into surface cracks) will eventually be discharged to <br />the North Fork as either springsJseeps or shallow groundwater return flow. MCC <br />recognizes that this may affect the "timing" of discharges into the North Fork, but the key <br />point is that water will be returned to the river. Also, as described later in this section, <br />given the large fault inflows in 1996 and early 1997, MCC has been a significant net <br />exporter of water to the river. <br />2. Springs -As discussed at length in Section 2.05.6 (3) (b) (iii & viii) Springs/Seeps, there <br />are no springs in the Apache Rocks and Box Canyon permit revision areas which are <br />within the fracture zone above the B-Seam or the combined caved/fractured zone above the <br />B and E-Seams. As such, no spring flow is expected to be lost to the mine workings. <br />Surface cracks could disrupt some of the colluvial springs, but this would ultimately result <br />in the downgradient displacement of the flows, and there would be no loss to the river. <br />3. Groundwater -There is extensive discussion in Section 2.OS.b(3)(b)(iii & viii), <br />Groundwater Quantity Effects, on groundwater impacts including fault system inflows and <br />underground storage of water. There are no "aquifers" in the current pernrit area. Most of <br />the groundwater resulting from primary porosity occurs in small, discontinuous "lenses." <br />2.05-171 Revisedhn. 1995 PR06; Revised Nov. 1998TR80; 1/98PR08 <br />
