Subject: Wake Stone Corporation- Knightdale Quarry
Mining Permit No. 92-06
Permit Modification Request
Dear Mr. Parr,
Enclosed are five copies of Mining Permit Application materials requesting modification of
Permit No. 92-06 for the Knightdale Quarry. The purpose of this modification is to expand the existing
quarry pit to the northwest. We are also requesting approval to construct a temporary access road to
the adjacent Hinton Oaks Industrial Park to provide borrow material. Permitting for the HOIP site has
been submitted to the Town of Knightdale by Wake Stone Property Company.
The enclosed permit modification application provides for a total of 16.73 acres of permanent
new land disturbing activities within the existing permit boundary. This area will be incorporated into
the existing quarry pit. The temporary access road will be a 30'-wide stone surface road (as shown on
the attached Site Plans) to allow off-highway haul trucks to transport borrow material offsite from the
pit expansion area.
We are also requesting as part of this modification the removal of 19.1 acres from the
westernmost mining permit boundary. This land is now owned and controlled by the Wake Stone
Property Company and is currently being developed as part of the Hinton Oaks Industrial Park. As
indicated on the attached Site Plan Map, the amount of land currently covered under this permit is
575.82 acres, with 322.84 acres approved for disturbance. Following the requested modification, 339.57
acres will be "affected," with the total acreage under permit reduced to 556.72 acres.
Pursuant to the Application Fee Schedule, we are enclosing our check in the amount of$750 for
the permit modification application processing fee. If you have any questions concerning this
modification request, please call me at(919) 266-1100.
Sincerely,
Wake Stone Corporation

C.PROTECTION OF NATURAL RESOURCES
1. Describe in detail the sequence of events for the development and operation of the mine and reference the sequence
to the mine map(s).Attach additional sheets as needed.
Knightdale Quarry is a currently operational crushed stone production facility, continuously operated
since 1970. This permit modification application is for the addition of 16.73 acres within the currently
permitted area (as indicated on the 2023 Permit Modification Site Plan/E&SC Map, sheet 1)to be
affected for the purposes of expanding the quarry pit. A ditch will be constructed to capture
stormwater runoff from the pit expansion area and divert all stormwater to the existing pit,where it
will be stored and used as make-up water for the process reservoir or discharged under the
provisions of NPDES General Permit No. NCG020030. As part of this modification, a temporary
access road will also be constructed to provide borrow material to the adjacent Hinton Oaks
Industrial Park as illustrated on the attached plans.
2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to
prevent offsite sedimentation (include specific plans forsediment and erosion control for mine excavation(s), waste
piles, access/mine roads, and process areas),and give a detailed sequence of installation and schedule for
maintenance of the measures.Locate and label all sediment and erosion control measures on the mine map(s)and
provide typical cross-sections/construction details of each measure. Engineering designs and calculations are required
to justify the adequacy of any proposed measures.
Silt fence will be installed as illustrated on the attached plans for the construction of the temporary
borrow access road and the diversion around the NW pit expansion area. The temporary access
road will be constructed with a stable stone surface comprised of 4-6"of"surge" base material (6"
minus). The NW diversion will direct all stormwater safely into the existing quarry pit. Where
required, clearing will initially only be done as necessary for construction of erosion control
measures. All erosion control measures will be seeded and stabilized immediately upon
completion. Once erosion control measures are in place, clearing, stumping, and grubbing will
begin in the pit expansion area and will continue in advance of stripping of overburden.
3. A)Will the operation involve washing the material mined, recycling process water,or other wastewater handling?
YES ❑NO
If yes,briefly describe all such processes including any chemicals to be used.
Production of washed stone is an ongoing activity at the Knightdale Quarry. Process/wash water is
contained in a non-discharging closed loop consisting of a reservoir and multiple settling cells. Washed
stone is produced at the rinse screen where used wash water is routed to a sand screw, hydro-cyclone,
and high frequency wet screen for production of classified screenings and stackable mineral fines.
MIDFLOC 1320L, a cationic flocculant liquid is metered in small volumes into the process water stream
at the sand screw overflow in order to increase settling efficiency in the settling cells.
B)Will the operation involve discharging fresh or wastewater from the mine or plant as a point discharge to the waters
of the State?
❑^ YES FINO
If yes,briefly describe the nature of the discharge and locate all proposed discharge points(along with their method of
stabilization)on the mine map(s).
Accumulated groundwater and stormwater runoff are collected in a pit sump and
used as make-up water in the closed-loop wash system, or discharged under
NPDES Permit No. NCG020030 when not needed for make-up. Discharge is
into a stable channel that ultimately leaves the site at SDO-1 as indicated on the
site plan maps.

C)Will any part of the proposed mine excavation(s)extend below the water table?
IYES ❑ NO
If yes, do you intend to dewater the excavation(s)?
YES NO
Estimated withdrawal rate in gallons per day: 918,000.00
If yes,what impact, if any,will mine dewatering have on neighboring wells?Locate all existing wells on the mine
map(s)that lie within 500 feet of the proposed excavation area. Provide data to support any conclusions or statement
made, including any monitoring well data,well construction data, and current water withdrawal rates. Indicate whether
the proposed mine locale is served by a public water system or private wells.
The 0.918 MGD average discharge rate indicated above includes precipitation
collected in the pit, as there is no way to separate groundwater from precipitation
runoff. Dewatering activities in crystalline formations such as the Rolesville granite
mined at the Knightdale Quarry have not been shown to have an adverse effect on
neighboring wells. Quarry facilities are served by a public water system, but the
old office well is still used for agriculture on site.
D)If you answered yes to any of the above questions,provide evidence that you have applied for or obtained the
appropriate water quality permit(s)(i.e.,non-discharge, NPDES, Stormwater,etc.)from the Stormwater Program. In
addition,the applicant is required to register water use with the Division of Water Resources, Ground Water
Management Branch,if the operation withdraws more than 10,000 gallons per day and needs a capacity use permit
from the Division of Water Resources, Ground Water Management Branch, if the operation lies in a capacity use area
and withdraws more than 100,000 gallons per day.
NPDES Permit No. NCG020030. A copy of the Certificate of Coverage for this
permit is included in this modification request package.
4. A)Will the operation involve crushing or any other air contaminant emissions?
YES ❑NO
If yes,indicate evidence that you have applied for or obtained an air quality permit issued by the Division of Air Quality
or local governing body.
Air Permit No. 3347. A copy of the cover page is included in this modification
request package.
B)How will dust from stockpiles,haul roads,etc.,be controlled?
Dust is controlled by wet suppression, including periodic wetting of haul road
and stockpile areas by water truck as needed.

5. A)A buffer will be required between any mining activity and any mining permit boundary or right-of-way. It may be an
unexcavated buffer(no excavation,but roadways, berms, and erosion&sedimentation control measures may be
installed within it),an undisturbed buffer(no disturbance within the buffer whatsoever),or a combination of the two,
depending upon the site conditions. Note that all buffers must be located within the mining permit boundaries.
How vide a buffer will be maintained between any mining activity and any mining permit boundary or right-of-way at
this site?A minimum buffer of 25 feet is recommended,although a wider buffer may be needed depending on site
conditions. Show all buffer locations and widths on the mine map(s).
See Site Plan Maps for established and proposed buffers. A minimum 25'
undisturbed buffer is dedicated around the entire Permit Boundary, including the
new property line/permit boundary change resulting from the removal of property
requested as part of this modification. Additional significant buffering is provided by
vegetated earthen berms along Forestville Road along the entire northern property
boundary, along the southeast boundary adjacent to the mobile home park, and
along the southwest boundary adjacent to the Home Depot shopping center.
B)A minimum 50 foot wide undisturbed buffer will be required between any land disturbing activities within the mining
permit boundaries and any natural watercourses and wetlands unless smaller undisturbed buffers can be justified.
Depending on site conditions, a buffer wider than 50 feet may be needed.
How wide an undisturbed buffer will be maintained between any land disturbing activities within the mining permit
boundaries and any natural watercourses and wetlands at this site?Show all buffer locations and widths on the mine
map(s).
Minimum of 50 feet. See attached site maps.
6. A)Describe methods to prevent landslide or slope instability adjacent to adjoining permit boundaries during mining.
Minimum 2 horizontal to 1 vertical slopes or flatter for clayey material and minimum 3 horizontal to 1 vertical slopes or
flatter for sandy material are generally required unless technical justification can be provided to allow steeper slopes.
Overburden cut slopes are established at 2H:1V and stabilized with vegetation.
As illustrated on site plans, significant setback is also provided between pit
development areas and Permit Boundaries.
B)Provide a cross-section on the mine map(s)for all fill slopes(berms, waste piles, overburden disposal areas, etc.),
clearly indicating the intended side slope gradient, installation of any benches and/or slope drains(with supporting
design information)if needed, and the method of final stabilization.

operation. The active mining and processing areas are located internal to the
large land area controlled by Wake Stone Corporation, providing hundreds of feet
of existing and enhanced vegetative screening from public view.
B)Could the operation have a significantly adverse effect on the purposes of a publicly owned park,forest, or
recreation area?If so,how will such effects(i.e.,noise,visibility,etc.)be mitigated?
No adverse effects from the on-going quarry operation are anticipated on any publicly
owned park or recreation area. The city of Knightdale's environmental park located along
Smithfield Road approximately 800 feet east of the quarry operation, and the Wake Stone
Athletic Park approximately 400 feet north of the quarry operation, are the nearest public
park/recreation properties. Both parks were developed on land donated by Wake Stone
Corporation.
11. Will ex losives be used?FXJYES ❑NO
If yes,specify the types of explosive(s)and describe what precaution(s)will be used to prevent physical hazard to
persons or neighboring property from flying rocks or excessive air blasts or ground vibrations. Depending on the mine's
location to nearby structures, more detailed technical information may be required on the blasting program(such as a
third-party blasting study).Locate the nearest offsite occupied structure(s)to the proposed excavation(s)on the mine
map and indicate its approximate distance to the proposed excavation.
ANFO and emulsion blasting agents are utilized for the production blasting at the
Knightdale Quarry. All blasting agents are brought on-site just prior to blasting
and loaded in blast holes by contract bulk dispensing truck. No blasting agents
are stored on site. Detonation of blasts is by electric caps utilizing a timing
board to maximize control of air and ground vibration. A seismograph is used to
monitor each blast at the nearest offsite occupied structure.

D.RECLAMATION PLAN
1. Describe your intended plan for the final reclamation and subsequent use of all affected lands and indicate the
sequence and general methods to be used in reclaiming this land.This must include the method of reclamation of
settling ponds and/or sediment control basins and the method of restoration or establishment of any permanent
drainage channels to a condition minimizing erosion,siltation and other pollution. This information must be illustrated
on a reclamation map and must correspond directly with the information provided on the mine map(s). In addition,
design information,including typical cross-sections, of any permanent channels to be constructed as part of the
reclamation plan and the location(s)of all permanent channels must be indicated on the reclamation map.
Knightdale Quarry has been continuously operated since 1970. With proven reserves and current
land ownership it is anticipated that the quarry may be operational for an additional 100+ years.
Given this anticipated long life of the operation, it is premature to foresee "final" reclamation of the
site. However, upon depletion of reserves and termination of operation of the Knightdale Quarry,
the pit will be allowed to fill with groundwater and surface runoff to create a lake. All plant
components will be disassembled and removed from the site. The process water settling basins
and sediment and erosion control basins will be drained and back-filled. All plant and stockpile
areas, on-site roadways, settling basin areas, and erosion control structures will be graded to
conform to surrounding land areas, and planted with wildlife food species and native vegetation.
2. Is an excavated or impounded body of water to be left as part of the reclamation?
FXYES F]NO
If yes,illustrate the location of the body(s)of water on the reclamation map and provide a scaled cross-section(s)
through the proposed body(s)of water.The minimum water depth must be at least 4 feet, measured from the normal
low water table elevation,unless information is provided to indicate that a shallower water body will be productive and
beneficial at this site.
Will the body(s)of water be stocked with fish?
❑X YES F ]NO
If yes,specify species.
At the time of final reclamation, the North Carolina Wildlife Resources
Commission will be contacted for assistance in determining the suitability of the
post-reclamation lake for fish stocking.
3. Describe provisions for safety to persons and to adjoining property in all completed excavations in rock including what
kind of permanent barricade will be left.Acceptable permanent barricades are appropriate fencing,large boulders
placed end-to-end,etc. Construction details and locations of all permanent barricades must be shown on the
reclamation map.
Suitable fencing and warning signs will be erected along the property boundary
where proximity to high walls constitutes a significant hazard.

The plant and stockpile areas and internal roadways will be graded to stable
configurations and seeded with various grasses, wildlife food species, and tree
seedlings.
B)Will any on-site roadways be left as part of the reclamation?
IYES �NO
If yes,identify such roadways on the reclamation map and provide details on permanent road and ditch line
stabilization.
The paved entrance road, the scales entrance and exit roads, and the paved
office parking areas will remain on site. Any needed additional ditch lines not
currently existing will be stabilized with riprap and vegetative linings as
necessary.
6. Describe the method of control of contaminants and disposal of scrap metal,junk machinery, cables,or other such
waste products of mining. (Note definition of refuse in The Mining Act of 1971.)
No off-site generated waste shall be disposed of on the mine site without prior written approval from the NC
Department of Environmental Quality,Division of Energy,Mineral,and Land Resources and either the Division
of Waste Management(DWM)or local governing body.If a disposal permit has been issued by DWM for the
site,a copy of said permit must be attached to this application.All temporary and permanent refuse disposal
areas must be clearly delineated on the mine map(s)and reclamation map, along with a list of items to be disposed in
said areas.
Scrap metal, junk machinery, cables, and other such mining generated wastes
are currently disposed of off-site in appropriate landfills or recycling facilities. It
is anticipated that this practice will continue throughout the future of the
operation, and that upon final reclamation, no such materials will remain on site.

APPLICATION FOR A MINING PERMIT
TYPICAL RE-VEGETATION PLAN
Site Preparation
Land surfaces will be graded and shaped as necessary to create topography applicable to the final
use of the land. Slopes in unconsolidated material will be graded to a stable slope not to exceed two
horizontal to one vertical. Loose rocks,woody material,and other obstructions that would interfere
with the establishment of vegetation will be removed and either buried or properly disposed of off-
site. Surface runoff will be controlled by use of diversions and terraces to allow discharge through
protected outlets.
Seed Bed Preparation
Lime and fertilizer will be incorporated into the soil to a depth of three to four inches on areas
where conventional equipment can be used. On slopes steeper than 2:1,soils will be scarified along
the contour for seed and nutrient retention. Lime and fertilizer will be applied according to soil tests
for the areas being re-vegetated,generally at a rate of 1,000 lbs. of 10-10-10 and 2,000 lbs. of lime
per acre. Newly seeded areas will be mulched with small grain straw spread evenly over the surface
at a rate of 1.5 to 2.0 tons per acre. One steep slope area not accessible to seeding equipment, seed,
nutrients, and mulch will be applied by hand.
Re-vegetation Species
Seed mixtures typically include some combination, depending on the season, of the following:
fescue, rye grain, bahiagrass, Kobe lespedeza, Korean lespedeza, sericea lespedeza, bicolor
lespedeza, white ladino clover, partridge pea, and native warm season grasses.
Fall or early spring plantings will utilize 100 lbs. fescue and 50 lbs. rye grain per acre. Late
spring plantings may include up to 40 lbs. Kobe/Korean lespedeza per acre where desirable to
supplement deer browse. Native warm season grasses will be utilized along with Kobe/Korean
lespedeza to enhance feeding and nesting areas for wildlife. Sericea lespedeza will be planted at a
rate of 20 to 40 lbs. per acre in combination with fescue when planting draughty soils or steep
slopes. Clover will be added to deer browse areas at a rate of 3-5 lbs.per acre in fall or early spring
plantings.
When using lespedeza species in fall plantings, non-scarified seed will be used. Scarified seed
will be used in spring plantings. When using clover in wildlife plantings, inoculated seeds will be
used.
Loblolly pine and red cedar seedlings will be planted at selected sites to provide visual screens.
Shrubs and Mast-bearing hardwoods such as those of the white oak subgenera may also be planted to
enhance wildlife habitat.

Each feature that is checked"Not Subject"has been determined to not be an intermittent stream,perennial stream,a
pond connected to a stream feature,or the feature is determined not to be present. Stream features that are checked
`'Subject"have been located on the property and possess characteristics that qualify it to be subject to the buffer
rules. There may be other streams located on the property that do not show up on the maps referenced above and are
therefore not subject to the buffer rules. However,if the stream features are present on the tract they are subject to
all other applicable North Carolina stream standards and permitting requirements as outlined in ISA NCAC 02B and
may be considered jurisdictional according to the US Army Corps of Engineers.
This on-site determination shall expire five(.5)years from the date of this letter, Landowners or affected
parties that dispute a determination made by the DWR may request a determination by the Director. An

Precipitation frequency(PF)estimates in this table are based on frequency analysis of partial duration series(PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90%confidence interval.The probability that precipitation frequency estimates(for
a given duration and average recurrence interval)will be greater than the upper bound(or less than the lower bound)is 5%.Estimates at upper bounds are not
checked against probable maximum precipitation(PMP)estimates and may be higher than currently valid PMP values.
Please refer to NOAAAtias 14 document for more information.

The rational formula is:
Q = CIA
where:
Q =peak rate of runoff in cubic feet per second(cfs)
C =runoff coefficient, an empirical coefficient representing the
relationship between rainfall rate and runoff rate
I = average intensity of rainfall in mchesfhour. for a storm duration equal
to the time of concentration, TC
A= drainage area in acres
The general procedure for determining peak discharge using the rational
formula is presented below and illustrated in Sample Problem 8.03a_
Step 1. Determine the drainage area in acres.
Total Drainage Area 16.7
Step 2. Determine the runoff coefficient, C. for the type of soiUcover in the
drainage area (Table 8.03b).
If the land use and soil cover is homogenous over the drainage area. a C
value can be determined directly from Table 8.03b. If there are multiple soil

corer conditions, a weighted average must be calculated, or the area may be
subdivided.
