Content:
dal currents, temperature, salinity, sedimentation rates, and sediment gradation and sorption characteristics. • Discussion of groundwater including, but not limited to, descriptions of aquifers and confining units, recharge and discharge areas and fluxes, groundwater head contour maps, hydraulic gradients, permeabilities, total and effective porosities, advective travel times, bulk density, and storage coefficients. • Groundwater transport characteristics (e.g., dispersion and adsorption coefficients), when necessary to evaluate impacts. DG-4026, Page 31 • Data concerning use of groundwater including drawdown caused by withdrawals from neighboring major industrial and municipal wells that may result in the transport of material from the site to these or other wells. • Maps or figures showing information requested above, as appropriate (e.g., areas affected by saltwater intrusion). 2.2.2 Water Use The applicant should provide present and known future surface-water, groundwater, and reclaimed water uses (as applicable) that could affect or be affected by building or operation, including for the following uses: public and self-supplied (or private) withdrawals for domestic, municipal, industrial, agricultural, mining, and power generation uses. Data and information provided for each use should include, but not be limited to, the following: • location and nature of water users and water-use areas; • distance from the station; • withdrawal rate by use category and return rate; and • statutory or other legal restrictions on the water use or the water resource. Additional information for groundwater use should include the following: • identification of the aquifer from which withdrawal occurs; • location and depth of wells; • identification of any U.S. Environmental Protection Agency (EPA)-designated sole source aquifers that may be affected by station building or operation; • characterization of consumptive and nonconsumptive water uses over the
