See <br />Map 2.04.7-1-A. WFC has also submitted a technical revision applications (TR-38, TR-47) to revise <br />the hydrological monitoring program as follows: <br />• Begin monitoring of the six new groundwaterwells (GW-N41, GW-N42 and GW-N43 up dip, <br />and GW-N44, GW-N45 and GW-N46 down dip). Table 2.04.7-1 shows the frequency and <br />• parameters to be monitored. <br />REVISED JULY 2006 2.04.7-48 <br />
