NOTES: Accuracy Specifications
1) Contours -Ninety (90) percent of the elevations determined from the solid Line Denotes Property BoundaryV
line contours of this topographic map has an accuracy with respect to
true elevation of one-half (1/2) contour interval or better and the remaining ten Existing Mining Permit Boundary
(10) percent of such elevations are not in error by more than one contour
interval. In densely wooded areas where heavy brush or tree cover fully obscures
the ground and the contours are shown as dashed lines, they have been plotted as
accurately as possible from the stereoscopic model, while making full use of
spot elevations obtained during ground control surveys and all spot elevations
measured photogrammetrically in places where the ground is visible.
2) This map was compiled by Garland Photogrammetric Services, L.L.C. using photogrammetric
methods. Contours portrayed as dashed or broken lines represent areas of dense vegetation
and should be considered approximate. This map has not been field verified.
Prior to use as a basis for design / construction, it should be field verified.
3) Buildings are shown roofline only.

Wake Stone Corporation NOTES: Accuracy Specifications
1) Contours - Ninety (90) percent of the elevations determined from the solid
Triangle Quarry line contours of this topographic map has an accuracy with respect to
true elevation of one-half (1 /2) contour interval or better and the remaining ten
Wake County (10) percent of such elevations are not in error by more than one contour
interval. In densely wooded areas where heavy brush or nee cover fully obscures
Mining Permit N o . 9 2 —10 the ground and the contours are shown as dashed lines, they have been plotted as /
accurately as possible from the stereoscopic model, while making full use of
Site Plan Map spot elevations obtained during ground control surveys and all spot elevations /
measured photo—mmetrically in places where the ground is visible
2020 Mining Permit Modification Existing
2) This map was compiled by Garland Photogrammetric Services, L.L.C. using photogrammetric
(Adding RDU Mineral Lease) methods. Contours portrayed as dashed or broken lines represent areas of dense vegetation
and should be considered approximate. This map has not been field verified. Sump
Last Revised: April 2, 2020 Prior to use as a basis for design / construction, it should be field verified.

Anticipated Depleted
Triangle Pit to at least
-170' (MSL) Elevation
The current pit sump will remain in place at an
elevation currently estimated to be at least 130'
above the final pit floor elevation, maintaining
separation of water used for make-ur water for the
process water reservoir and/or discharged as pit
dewatering wastewater. Smaller portable pumps may
be utilized to transfer water from lower pit levels (as
they are currently) to the sump as needed:

Once appropriate E&SC measures are installed around
Triangle Quarry perimeter road improvement areas,
construction will begin at the easternmost point and ✓
ro ress to the west. The proposed method of
P g P P
construction for the cut areas of the road will ensure all
drainage is diverted into the existing pit via super
elevation of the road surface as illustrated by cross
sections above. En sneered retaining walls along fill
g g g
areas will be constructed and fill laced and compacted

to ensure all drainage is diverted into the existing pit or
to Temporary Basin 7. Safety berms, large boulder
barricades, or concrete block barricades will be utilized 14/ ll /�/ //////%/ //it
to meet MSHA safety requirements along any rollover
' hazard areas. This phase of perimeter road improvement
will also include filling and grading of pre-existing
/ SDO-4 basin and Temporary Basin 7 to divert all //// ///�/%// ,� ///

abatement will be provided along Umstead State Park
facia areas b the inclusion of a 14 h1 h solid barrier
