MINREC, INC., BLUE RIBBON MINE <br />2003 ANNUAL HYDROLOGIC REPORT <br />JANUARY 1, 2003 THROUGH DECEMBER 31, 2003 <br />INTRODUCTION <br />The Blue Ribbon Mine went into permanent cessation in 1986 and the majority of reclamation was <br />completed that year. A minor amount of grading was done in 1987 on the portal bench to improve <br />drainage. During 1988, 1989 and 1993 portions of the bench cover material slumped and were <br />repaired and seeded. <br />The hydrologic monitoring plan is contained in the permit document, pages 124 and 124a which <br />were revised July 28, 1994 and October 10, 1995 respectively. Exhibits H-1 and Z show the <br />various monitoring locations. <br />SURFACE WATER <br />The following table shows the flow, pH and conductivity for upstream and downstream Hubbard <br />Creek by quarter for 2003 compared to the same month averages from 1982 through 2003. <br /> Upper Hubbard Creek Lower Hubbard Creek <br />Quarter Parameter AVE 2003 AVE 2003 <br /> <br />1st Flow, cfs 22.1 10.6 - - <br /> pH 8.1 8.7 8.1 8.6 <br /> Cond-umhos/cm 202 252 215 265 <br />2nd Flow, cfs 28.2 5.3 - - <br /> pH 8.1 8.8 8.1 8.6 <br /> Cond-umhos/cm 221 187 230 195 <br /> <br />3rd Flow, cfs 5.7 0.9 - - <br /> pH 8.2 8.4 8.1 8.4 <br /> Cond-umhos/cm 252 312 272 322 <br />4th Flow, cfs 6.5 N/A - - <br /> pH 8.1 7.9 8.1 7.6 <br /> Cond-umhos/cm 221 230 246 280 <br />N/A -Hubbard Creek was frozen so there was no way to determine flow. <br />
