Therefore, the roadway disturbance acreage has <br />been increased and the disturbance acreage of the facilities has been decreased. <br />applicable technical revision plan. Laboratory analytical reports were transmitted to the Division <br />upon receipt from the laboratory. <br />Lysimeters were inspected monthly and reported to the Division. The Iysimeters remained dry <br />throughout the year. <br />Ground water sampling and analysis of the San Luis town and the Shalom Ranch wells were <br />conducted in accordance with the applicable technical revision monitoring plan. Laboratory <br />analytical reports were distributed to the Division and the other applicable parties upon receipt <br />from the Laboratory. <br />Tailing facility underdrain flows were monitored at the base of the embankment to determine the <br />rate of underdrain return flow to the collection pond. The 2002 underdrain flow rates ranged <br />from 40.88 to 52.46 with a mean annual underdrain flow rate of 45.59 gpm. <br />Stream staff gauges were monitored and reported as required until TR-32 approval was received <br />at that time the staff gauges were removed from the sites in accordance with the TR-32 <br />monitoring plan. <br />
