Notes:
a. This permit approves the redefined footprints of Cells B and C at the Phase 1 area
consistent with the revised Facility Plan map Drawing No. E1B/ Sheet No. 3B (DIN
12796).

b. The gross capacity of Phase 1, Cell B is reduced to 186,242 cy from the original
approved capacity of 192,470 cy. The reduction of capacity of 6,228 cy resulted
from the as-built grades of Cell B having an average of 2-feet higher than the
originally designed grade over approximately 1.9 acres (DIN 12795).

c. The gross capacity of Phase 1, Cell C is reduced to 221,720 CY from the original
approved capacity of 223,664 CY based on the as-built grades. The capacity
reduction in Phase 1 development results in the new total gross capacity of the
landfill of 2,231,847 CY. (DIN 17547). The originally approved total gross capacity
for the C&DLF unit is 2,240,000 CY (DIN 6225) and A-1 Sandrock, Inc. may not
cede capacity at this permit action.

d. The gross capacity of Phase 2, Cells A & B are revised due to adjustment of the final
base grade elevations at Cell A. The approved gross capacity of 608, 193 CY for
Phase 2 is not changed.

2. Pursuant to N.C.G.S. 130A-295.8(b)(1), construction of any future phases or cells of the
C&DLF unit – Phases 3 and 4 is considered as a “Major Permit Modification” and requires
written approval of the Section. Application for Permit Approval to Construct must be
prepared in accordance with applicable statutes and rules in effect on that date.
