! 3.2.1 Plant Water Use i

i Estimates of plant water use, including withdrawal rates and consumptive use rates have changed since the issuance of the CP-FES.

Table 3.3-1 and Figure 3.3.12 of ER provide the required information, i

The maximum values for consumptive use were changed from 16,500 gpm (1.0 m3 /sec) to 12,877 gpm ("8 m3 /sec). .

2-Small quantities of groundwater (standby well water supply) will be withdrawn for makeup demineralized and potable water. This supply, consisting of two wells with a combined capacity of 500 gpm (.03 m3 /sec) would be used if the norr;al . sources of water would fail.

5.3.6 Effects on Surface Water Supply The conclusions presented in Section V.B CP.fES remain valid.

5.3.7 Effects on Groundwater The two wells which supply water to the standby well water system would be used infrequently and therefore would not significantly impact groundwater use or lehels in the site area. Some changes

~

have occurred to groundwater levels (as discussed in Section 2.3.3).

These changes are minor and should have no effect on the overall ground-water system in the area.

6.3.3 Groundaater Studies The Departrient of Energy (DGE) has conducted extensihe programs for monitoring of characteristics of groundwater in the Hanford Reservation. Theseprogramshaveaccumbl3tedcomprehensihedata.

DOE is expected to continue the program. Tne applicant, therefore, expects to do no additional monitoring, and rely instead on the monitoring by DOE.
