<br /> <br /> <br /> 30 C1981-041 RN7 findings <br />were sewage lagoons, and three non-discharging sumps. A set of evaporative, non- <br />discharging sewage lagoons were permitted near the loadout for treating water from <br />the Roadside Mine and the loadout. The sewage lagoons have been reclaimed. <br /> <br />Two small sumps were constructed in the North Decline reclamation area and one <br />sump was constructed in the Cameo Borrow Area #1 (CBA-1) to serve to capture and <br />treat runoff from reclaimed lands. These sumps were adequately sized to contain <br />runoff from a 25-year, 24-hour storm event. Both sumps were reclaimed following <br />approval of PR-5. <br /> <br />G. Surface and Ground Water Monitoring <br /> <br />The permittee conducted monitoring of groundwater in a manner approved by the <br />Division. The groundwater monitoring plan is detailed in Tab 18 of the permit <br />application. Piezometers have been installed in various permit area locations to <br />monitor water level and/or quality in alluvium, refuse fill, the Rollins Sandstone <br />and abandoned sections of the South Portals Mine. Monitoring locations are shown <br />on “Roadside and Cameo No.1 Mines Hydrologic Monitoring Map” (Exhibit 56), in <br />Tab 18. The groundwater monitoring plan is outlined below; for additional detail <br />refer to Tab 18 of the approved permit. (4.05.13(1)): <br /> <br />Unit Train Loadout Piezometers <br /> <br />Quarterly water level monitoring UTL-01,02,03,04; Annual water quality monitoring <br />UTL-02 and UTL-04 (parameters listed in Permit Table 18-3); Monitoring of UTL- <br />01, 02, 03 & 04 Piezometers was discontinued in April 2011 with the approval of SL- <br />7 and they were abandoned and reclaimed in May 2011. <br /> <br />Roadside South Portal Workings <br /> <br />Well N-1, located at reclaimed North Decline; quarterly water level monitoring. <br /> <br />Rollins Sandstone Wells <br /> <br />Rollins-2 (At UTL) and Rollins-3 (Near Pond 7, North Decline) <br /> <br />The Rollins Sandstone wells were installed in the summer of 1997 in large part to <br />address questions raised by the Division in the 1995 mid-term review and review of <br />PR-02, regarding the hydrologic characteristics of the Rollins Sandstone within the <br />permit area. Quarterly water levels and Annual water quality analyses (Table 18-3) <br />required for Rollins Wells. Monitoring of in-mine wells (Rollins-1 and Rollins-4) has <br />been discontinued because the portals have been sealed and the wells are therefore no <br />longer accessible. Monitoring of Rollins-2 and Rollins-3 wells was discontinued with <br />the approval of SL-7 in April 2011 and they were abandoned and reclaimed in May <br />2011. <br />
