Introduction <br />Tha iaformstioa assembled is this 1995 Annual Hydrology Aeyort (A811) includes data <br />collected from approved egaitorinq •itas sstsbliehaQ at Banace Coal Co~npy'• (HCC) Yoact <br />Mina (6tata Permit No. C-94.OH7). Locations of moaitorlaq sites diseueead is thi• repast <br />can Da found by referring to Exhibit 7.1, Hydrology Monitoring Map, rhich may be found is <br />the Yoaei Mine Permit Ayylieatioa Package (PAP). <br />The Yoact PAP included data up to December 31, 1993. Thi• first A88 includes data <br />collected betrean January 1, 1994 to 8eytember 30, 1995. All tablet referred to in the <br />following text csa be found is ApysaQix A.

Foz convenience Bake, this <br />table has bnea placed at the anQ of the Table of Contents (sea previous papa). <br />The Yoaet Miaa Dermit rant into affect oa August B, 1995. No mining has occurred yet; [ha <br />only Qiaturbaaca has bean the eoas[ructioa of a haul road. Ae a result, data in this AHA <br />may still ba considered as baseline data. Because of this, the discussion of data yraeeat <br />here will be minimal. A mars ec~lata discussion of data will ba yrovided in future AHRc. <br />Metaosologienl Dnta <br /> No mataoro logical data is collected et the Yoast Mina. 6CC maintains a weather station <br /> (windspaed cad flizactioa, tas~arntura sad praciDita[ioa) at its adjecsat 6aneea II-W Miae. <br /> The render ie referred to that AHR, Aypaadix H.
