operations/monitoring will be evaluated. Monitoring activity in <br />1990 exceeded the required BLM, EPA and CMLR (Colorado Mined Land <br />Reclamation) requirements for initial cavities. Figure 2-1 <br />illustrates location of monitoring wells completed in 1990. <br />2.5.2 Scove <br />Hydrology monitoring concentrates on ground water monitoring as <br />there are no perennial streams or springs located on the sodium <br />leases. An evaluation of possible springs on the lease and <br />pumpage effected areas was conducted in 1990. HRS Water <br />Consultants were contracted to project the cone of depression <br />based on current plant location and projected water well pumpage <br />rates. No springs were found within the cone of depression based <br />on a review of USGS and BLM survey results, and field inventory. <br />See Figure 2-5 for cone of depression. <br />2.5.3 Stream Gauging Stations <br />As required by the ROD, NaTec contracted for surface water <br />monitoring of water quality and quantity upstream and downstream <br />of the cone of depression on Yellow and Piceance Creeks. This was <br />done in cooperation with the USGS on four existing stations with <br />extensive historical data. Data collection started July 1, 1990. <br />Data will be reported to the BLM upon receipt from the USGS. <br />• <br />32 <br />_„_ <br />
