CRDA -01 through 03, and O1A; and thirty piezometers (Pz 100 -107, 200 -206, 300 -307, and <br />400 -406), all on CRDA -1, monitored quarterly for water level. "Critical levels" defined for 100, <br />200, 300, and 400 series piezometers. <br />CRDA -04 through 06 installed on CRDA -2, monitored quarterly for water level. <br />Unit Train Loadout Piezometers <br />Quarterly water level monitoring UTL- 01,02,03,04; <br />Annual water quality monitoring UTL -02 and UTL -04 (parameters listed in Permit Table 18-3); <br />Monitoring of UTL -01, 02, 03 & 04 Piezometers was discontinued in April 2011 with the <br />approval of SL -7 and they were abandoned and reclaimed in May 2011. <br />Roadside South Portal Workings <br />Well N -1, located at reclaimed North Decline; quarterly water level monitoring. <br />Rollins Sandstone Wells <br />Rollins -2 (At UTL) <br />Rollins -3 (Near Pond 7, North Decline) <br />The Rollins Sandstone wells were installed in the summer of 1997 in large part to address <br />questions raised by the Division in the 1995 mid -term review and review of PR -02, regarding the <br />hydrologic characteristics of the Rollins Sandstone within the permit area. Quarterly water <br />levels and Annual water quality analyses (Table 18 -3) required for Rollins Wells. Monitoring of <br />in -mine wells (Rollins -1 and Rollins -4) has been discontinued because the portals have been <br />sealed and the wells are therefore no longer accessible. Monitoring of Rollins -2 and Rollins -3 <br />wells was discontinued with the approval of SL -7 in April 2011 and they were abandoned and <br />reclaimed in May 2011. <br />The Roadside Mines are required to submit to the Division an Annual Hydrologic Report that <br />provides information on the water quantity and quality for both the surface and groundwaters in <br />the permitted area. In addition, quarterly NPDES reports are submitted to the Division and the <br />Department of Health to comply with the current laws governing point sources. In the event of <br />an effluent discharge that is not within compliance parameters, a written notice will be forwarded <br />to the Division and the Department of Health. <br />Groundwater monitoring wells are located in both the Rapid Creek and Cottonwood Creek <br />basins. GWMS 02a and 02b are upstream on Cottonwood Creek, GWMS 03a and 03b are <br />upstream on Rapid Creek, while GWMS 01a and Olb are downstream on Rapid Creek <br />(downstream from the confluence with Cottonwood Creek). These wells have been placed to <br />monitor surface subsidence impacts on creek flows in the southern permit area; therefore, water <br />level is the only parameter measured. <br />CRDA -1 and CRDA -2 piezometers are monitored for water levels on a quarterly basis (thirty - <br />four on CRDA -1 and three on CRDA -2). The thirty, 100 through 400 series piezometers on <br />CRDA -1 were installed in 1994 at four locations to monitor water levels in multiple zones within <br />Permit Revision No. 5 26 July 10, 2012 <br />
