ENCLOSURE Supplemental Information Associated with Environmental Report Figures Supplemental Information:

Item 1:

During the public meeting held on August 14, 2017, the NRC staff requested verification of the source data used in the development of ER Figures 2.2-2 and 4.1-1 .

TVA reviewed the source data used to produce ER Figures 2.2-2 and 4.1-1 and confirmed that National Land Cover Database (NLCD) 2011 is the correct source for the information presented .

Based on this confirmation , no change to ER Figures 2.2-2 and 4.1-1 is required.

Item 2:

During the public meeting held on August 14, 2017, the NRC staff requested clarification of the source data used in the development of ER Figures 2.4.1-1 and 4.3-1 .

The source data used to inform ER Figures 2.4.1-1 and 4.3-1 were CRN Site and Barge/Traffic Area (BTA) field surveys conducted by TVA biologists to characterize vegetation communities, wetlands, and ponds. The findings from these surveys are described in ER Subsection 2.4.1.1, "Upland Habitats," and ER Subsection 2.4.1.2, "Wetland Habitats." Based on the interpretation of aerial imagery, in conjunction with the descriptions of vegetation communities, wetlands, and water bodies provided by these field surveys, dominant vegetation communities and other land cover types were delineated on aerial photographs by hand . This information was converted to Geographic Information Systems (GIS) layers and mapped using GIS to create ER Figures 2.4 .1-1 and 4.3-1 . Acreages for the land cover types were then calculated using the GIS polygons (shown in the figures) . Acreages for the land cover types are summarized in ER Table 2.4.1-1 . As noted in ER Table 2.4.1-1 , wetland acreages were accounted for in the vegetation community type in which they occur (i.e ., deciduous forest , mixed forest, or herbaceous).

ER Figures 2.4.1-1 and 4.3-1are being revised to include the source data references . In addition, ER Table 2.4 .1-1 , Note 1 is being revised to reflect the method used to develop the land cover types.

Item# 3:

The NRC staff requested clarification concerning the GIS files associated with ER Figure 3.1-2.

Specifically, the NRC staff requested that TVA confirm that the GIS files provided in Reference 3 were the correct files for ER Figure 3.1-2.

TVA reviewed the information submitted to the NRC in Reference 3 and identified that the GIS layer file (map package [.mpk]) associated with ER Figure 3.1-2 was incorrect. The correct GIS layer file for ER Figure 3.1-2 is being provided on the enclosed CD-ROM disk.
