MINREC, INC., BLUE RIBBON MINE <br />2001 ANNUAL HYDROLOGIC REPORT <br />JANUARY 1, 2001 THROUGH DECEMBER 31, 2001 <br />INTRODUCTION <br />The Blue Ribbon Mine went into permanent cessation in 1986 and the majority of <br />reclamation was completed that year. A minor amount of grading was done in 1987 on the <br />portal bench to improve drainage. During 1988, 1989 and 1993 portions of the bench <br />cover material slumped and were repaired and seeded. <br />The hydrologic monitoring plan is contained in the permit document, pages 124 and 124a <br />which were revised July 28, 1994 and October 10, 1995 respectively. Exhibits H-1 and Z <br />show the various monitoring locations. <br />SURFACE WATER <br />The following table shows the flow, pH and conductivity for upstream and downstream <br />Hubbard Creek by quarter for 2001 compared to the same month averages from 1982 <br />through 2001. <br /> Upper Hubbard Creek Lower Hubbard Creek <br />Quarter Parameter AVE 2001 AVE 2001 <br /> <br />1st Flow, cfs 23.5 7.8 - - <br /> pH 8.1 8.2 8.1 8.3 <br /> Cond-umhos/cm 199 200 213 190 <br />2nd Flow, cfs 30.6 6.1 - - <br /> pH 8.1 8.5 8.1 8.4 <br /> Cond-umhos/cm 222 180 231 190 <br />3rd Flow, cfs 6.0 2.7 - - <br /> pH 8.2 8.0 8.2 8.2 <br /> Cond-umhoslcm 252 210 262 200 <br /> <br />4th Flow, cfs 6.5 2.9 - - <br /> pH 8.1 8.2 8.1 8.5 <br /> Cond-umhos/cm 221 190 242 190 <br />
