See Map 2.04.7-1-A. WFC has also submitted a technical revision applications <br />(TR-38, TR-47) to revise the hydrological monitoring program as follows: <br />• Begin monitoring of the six new groundwater wells (GW-N41, GW-N42 and GW-N43 up <br />dip, and GW-N44, GW-N45 and GW-N46 down dip). Table 2.04.7-1 shows the <br />frequency and parameters to be monitored. <br />• After the initial monitoring of each of the six (6) holes, the old monitoring holes GW-N13, <br />GW-N14 and GW-N15 will be abandoned. Abandonment reports will be submitted to <br />
