Resolved 2. Resolved 3. SCC revised the text as requested, but a few inconsistencies remain. a. Table 1 on page 5 of the bond release application narrative shows that the Total All Hit Allowable Herbaceous Cover of the Phase II Bond Release Block was 43.2 percent. The paragraph immediately following the table says it is 42.97 percent. Table 3 on page 6 gives a value of 45.02 percent. Please revise the pages so that the tables and narrative are consistent. Please note the data will be revised with the removal of the three landslide area transects; the tables and text should be updated based on the final data from the remaining 26 transects. b. In Table 1 on page 5 of the bond release application and on Page 13 of Attachment E, under the Sagebrush Extended Reference Area, mean allowable cover is listed as 35.8 percent. The narrative on page 10 of Attachment E lists it as 36.3 percent. Please revise the text to be consistent with the data. c. Pages 5 and 6 give conflicting values for the Steep Mountain Brush Extended Reference Area; Table 3 says 17.5 percent and Table 1 says 17.3 percent. Please revise the tables for consistency. Response: The tables and narrative have been revised for consistency with the new data. 4. Resolved 5. Resolved 6. Resolved Seneca Coal Company • P.O.
