On January 25, 1999 at 0800 WRN personnel <br />reported excess surface water flowing to the erosion control basin near the scale building. An <br />investigation of the area indicated water was seeping up in the haul road, used to exit the scale <br />building. A buried pipeline is in the area where seepage was observed. The source of the seepage <br />was confirmed when the pump was turned oft at the process pond. The process pond return flow <br />will remain offuntil pipe is repaired (work scheduled for 1/27/99). [t is difficult to estimate the <br />amount of leakage. The area is mainly rock where cut was made for facilities and pipeline trench. <br />Therefore, 25,200 gallons of surface water was removed and was the basis for estimated leakage <br />of 26,000 gallons. All leakage was contained in erosion control basins and hauled to process <br />pond. As leakage was contained on the facility area, no damage to the surrounding vegetation is <br />anticipated. <br />If there are any questions, please contact Bob Warneke or me. <br />Sincerely, <br />~~J~!~~ <br />Ed Baker, REM <br />EnvironmentaUSafetyhanager <br />cc: Colorado DMG <br />Corporate E/S PAanager <br />White Rlvar Nahcolite Mlnarals, Llmlted Llablllty Company <br />P.
