Runoff/Absorption Runoff from the project site is discussed in Section 2.10 Surface Water Runoff and Section 2.8.2.4 Site Stormwater System.

The new point of withdrawalwill be the power plant location, to permit reuse of the stormwater. Any stormwa_er captured for the power plant use results in a corresponding reduction in groundwater withdrawals form the gravel aquifer located under the proposed power plant and the Boise Cascade Corporation fiber farm. Therefore, capture of srormwater for beneficial re-use has no net impactupon the aquiferresourcesand isnotincludedintb.ccalculationof wateruse requirements described in Section 2.5 Water Supply System. The additional point of withdrawal is acceptable froma hydrogeologic standpoint because the same body of water is involved and stormwater capture win affect existing water rights the same as the existing withdrawal locations. The on-site makeup water supply well(s) will be used…
