ta included in the SAR may be obtained from NOAA’s National Climatic Data Center, Regional Climate Centers, or State Climate Offices. The USACE Cold Regions Research and Engineering Laboratory holds accumulated freezing degree-days data that is sufficient to evaluate icing on lakes and storage reservoirs. Historical data related to hurricanes, storm surges, seiches, and tsunamis, collected and maintained by NOAA, are also used in staff’s review of these hydrological mechanisms. 3. Surface and Ground Water Uses: The staff reviews data on surface and ground water users, location with respect to the site, type of use, and quantity of water used to review the availability and reliability of safety-related water supply to the plant. Inventories of current and likely future water users, consistent with regional hydrologic inventories reported by applicable State and Federal agencies, are used in the staff’s evaluation. 4. Data: The staff reviews the identification and description of all spatial and temporal data that are used in the review of subsequent SRP sections. Spatial data may be presented 2.4.1-8 Revision 3 - March 2007 in a GIS format with a description of the computer software used to create the GIS layers. Temporal data may be presented electronically along with a description of the data format. The staff anticipates the use of the following data in the review of SAR Section 2.4: A. Spatially referenced data i. Topographic and bathymetric data including elevation contours ii. Location coordinates of the center of the powerblock and plant perimeter envelope iii. Locations of streamflow gauges iv. Locations of meteorological stations v. Locations of water control structures including dams and reservoirs vi. Locations of onsite or immediately adjacent water control, storage, or conveyance structures such as canals, dikes, levees, etc. vii. Locations of surface and ground water users viii. Maps of soil types and subsurface characteristics identifying aquifers
