~J <br />MINREC, INC., BLUE RIBBON MNE <br />2005 ANNUAL HYDROLOGIC REPORT <br />JANUARY 1, 2005 THROUGH DECEMBER 31, 2005 <br />• <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 various <br />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 2005 compared to the same month averages from 1982 through 2005. <br /> Upper Hubbard Creek Lower Hubbard Creek <br />Quarter Parameter AVE 2005 AVE 2005 <br /> <br />1st Flow, cfs 23.5 17.6 - - <br /> pH 8.1 8.4 8.1 8.6 <br /> Cond-umhos/cm 206 240 217 220 <br /> <br />2nd Flow, cfs 33.5 105 - - <br /> pH 8.2 8.5 8.1 8.1 <br /> Cond-umhos/cm 211 80 220 70 <br /> <br />3rd Flow, cfs 6.3 2.4 - - <br /> pH 8.2 8.2 8.2 8.3 <br /> Cond-umhos/cm 248 210 263 200 <br /> <br />4th Flow, cfs 6.7 9.7 - - <br /> pH 8.1 8.6 8.1 8.2 <br /> Cond-umhos/cm 217 200 239 200 <br /> <br />
