• DESCRIPTION OF THE HYDROLOGIC MONITORING PROGRAM <br />The hydrologic program followed for the Carbon Junction Mine is described below. With <br />the approval of Technical Revision 03 in April 1997, the original hydrologic monitoring <br />program for the mine was modified. Technical Revision 03 modified the sampling <br />frequency for springs and groundwater wells to semi-annual, with the exception of <br />groundwater well 95-1, which was to be sampled quarterly in 1997, and semi-annually <br />thereafter. The springs to be monitored were identified as 1, 2, and 4. The groundwater <br />wells to be monitored were 17-B, 82-1, 82-4, and 95-1. <br />During the review of Technical Revision 08 in late 1997, an in-depth analysis of the <br />hydrologic monitoring program was undertaken. It was acknowledged that several <br />springs and groundwater wells had been either mis-identified or identified with multiple <br />designations. The hydrologic monitoring program was modified in the permit text to <br />clearly identify the springs and groundwater wells to be sampled. <br />The current hydrologic monitoring program (page 5-36 of the permit document) requires <br />the semi-annual sampling and analysis of springs 1 (upper Carbon Junction Canyon), 3 <br />(REA Canyon below the mine), and 4 (Carbon Junction Canyon below the mine) when <br />flowing, and the semi-annual sampling and analysis of groundwater wells 17-B (above the <br />mine), 94-1 (mid-mine), and 95-1 (below the mine). <br />• During the permit renewal process in 1998, Technical Revision 09 clazified the parameters <br />to be analyzed when sampling is conducted (page 5-36a). <br />Spring Monitoring <br />Spring 1 (Upper Carbon Junction Canyon) did not flow during water year 1999. This <br />spring has been dry since the eazly 1980's. Spring 3 (REA SPG #3) was sampled in <br />October 1998 and April 1999. Spring 4 (CJ-LO-SPG #4) flowed and was sampled in <br />April 1999. Additionally, CDMG requested that Oakridge Energy sample discharge from <br />the spring identified as the HauUoad Spring, located above the haulroad and below the <br />south pit. This spring was sampled in November 1998. Spring monitoring included a <br />full-suite laboratory analysis as well as collection of field parameters of pH, conductivity, <br />temperature, and flow. <br />Well Monitorine <br />The groundwater wells which were monitored in water yeaz 1999 were 17-B (upgradient <br />of the mine), 94-1 (located mid-mine), and 95-1 (located downgradient of the mine). All <br />wells were monitored two times during water yeaz 1999; once during the first water year <br />quarter (October 1998), and once during the third water yeaz quarter (April 1999). A full- <br />suite analysis of parameters was conducted along with a field analysis of pH, temperature, <br />depth to water, and electrical conductivity. <br />~J <br />-2- <br />
