Pre-2008 Closure Activities

The following publically sourced aerial photo clearly shows the north and east sides of Phase 2A on
grade with final cover applied, prior to the map date of January 2, 2008. The young vegetation is
sparse, as this photo shows winter conditions. Nonetheless, these slopes are technically closed,
and the progression of aerial photos from 2008 to present (found in Google maps) shows no further
disturbance. This area coincides with the 2.9 acres of required closure addressed in the 2014 PTO
(DIN 9575), Attachment 3, Part 1, Condition 2. Based on the November 24, 2014 SCS Engineers
report (DIN 28336), the final cover on these slopes, evaluated with test holes #1 - #15, was
documented as having the minimum 24 inches of cover as required by Rule 15A NCAC 13B .0510.
