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.
Overburden material(dirt)and sap rock present above the hard rock will be removed. The rock
is drilled and blasted to produce a product that can be transported to the plant for processing.
From there, the raw material is crushed and screened to produce desired products. A
construction sequence of land disturbing activities is provided on the Mine Map, specifically as it
relates to sediment and erosion control. Maintenance and stabilization efforts will be conducted
as noted and as required in the mining act.
2. Describe specific erosion control measures to be installed prior to land disturbing activities and during mining to
prevent offsite sedimentation(include specific plans for sediment 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 maps)and
provide typical cross-sections/construction details of each measure.Engineering designs and calculations are required
to justify the adequacy of any proposed measures.
Sediment and erosion control measures will be installed in accordance with the Mine Map and
construction details. These measures will be installed prior to disturbing the area they are
designed to protect. The construction sequence indicates the steps that will be taken to maintain
all of the sediment and erosion control measures. Temporary diversions are provided to direct
all surface runoff through the sediment basins. Design calculations are provided on the Mine
tia.rJ Map to support the dimensions and construction of the proposed sediment basins. The majority
of runoff from the property will be maintained internally, either from the pit or the existing
sediment basins.
3. A)Will the operation involve washin the material mined,recycling process water,or other wastewater handling?
AYES NO
If yes,briefly describe all such processes including any chemicals to be used.
Process wash water from material washing is treated through a recycling system within the
settling cells. The system is further described in the General NPDES permit issued to the mining
industry and specifically, NPDES Permit#NCG020169 for this facility.
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 -]NO
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).
Water discharged as a result of mine dewatering is comprised of storm water&processing area
runoff and groundwater seepage. This water will gravity flow to the pit sump for clarification prior
to discharge. Water collected in the pit will be used to replenish the recycling system or
replenish the existing fresh water pond on the property. Any accumulated water that is not
needed,will be discharged through the approved outfall location,specifically Outfall 001 shown
on the Mine Map discharges into Killians Creek. Discharge water from the outfall will be tested
for pH,Turbidity,Total Suspended Solids, and Settleable Solids; in accordance with the
requirements of General NPDES Permit requirements to ensure that water quality standards are
met.

C)Will any part of the proposed mine excavation(s)extend below the water table?
AYES FINO
If yes,do you intend to dewater the excavation(s)?
a YES NO
Estimated withdrawal rate in gallons per day: 1.0 Million Gallons
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 close proximity of the rock to the surface of the ground and the low level of permeability of
the rock in the quarry area indicate that the quarry development will have no detrimental impact
on any wells in the area.
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.
The process is described in the General NPDES permit issued to the mining industry and
specifically, NPDES Permit No. NCG020169 for this facility. This permit authorizes the
discharge of storm water, process water,and mine dewatering to the surface waters of North
Carolina.
4. A)Will the operation involve crushing or any other air contaminant emissions?
1^1YES FINO
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.
The NC DEQ Division of Air Quality has issued air Permit No.05571 for this facility.
B)How will dust from stockpiles,haul roads,etc.,be controlled?
Fugitive dust from the processing plant, stockpiles, etc.will be controlled through the use of a
wet suppression system within the operating plant. A large water truck will be used to control the
dust on the haul roads, pit area and within the stockpile area. A large portion of the annual
production will consist of washed stone,which generates little dust.

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).
Existing streams within the permit boundary will have a 50' undisturbed buffer.
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.
To assure slope stability adjacent to adjoining properties during mining, slope and excavation
configurations will take into account structural geology, rock mechanics, and mining engineering
considerations. Final excavation grades for all unconsolidated overburden material will be on a
2:1 minimum slope around the outer quarry perimeter from natural ground to the top of bedrock.
Further,a minimum ten-foot(10')wide safety bench will be provided at the base of any cut slope
and the top of bedrock in this same area.
B)Provide a cross-section on the mine map(s)for all fill slopes(berms,waste piles,overburden disposal areas,etc.),

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(ammonium nitrate and fuel oil)and water-based emulsions are the primary-blasting agents used. Blasting will be
conducted under the direction of experienced and qualified personnel. Blasts will be monitored at all times by
seismograph to ensure that vibration and air blast levels are within the guidelines set by the State. Shot patterns will be
designed in consideration of the geological environment,(i.e.,faults,fractures,and lithology)maximize material
breakage,and prevent any physical hazards to persons or neighboring property. Blast designs will also be based upon
the distance to the nearest dwelling from the blast site and the weight of explosives per blast interval(pounds detonated
per eight(8)millisecond delay),which will consistently yield predictable blast vibration levels well within all regulatory
limits at subject structures.Records of each blast will be maintained,and will include pertinent data such as the number
of holes,pattern,delay intervals,depth and size of holes,type and total pounds of explosives,maximum pounds per
delay interval,amount of stemming and burden for each hole,and blast location. Blast and seismograph records will be

5. A)Describe reclamation of processing facilities,stockpile areas,and on-site roadways.
All processing facilities will be dismantled. Salvageable equipment will be hauled off-site for use
at other Martin Marietta operations. Equipment that cannot be reused will be disposed/recycled
in accordance with all local,State, and Federal regulations. Stockpiles will be removed, and the
affected area graded to conform to surrounding topography. These areas will then be scarified
and re-vegetated. Haul roads and roadways not necessary for future development will also be
scarified and re-vegetated
B)Will any on-site roadways be left as part of the reclamation?
YES �NO
if yes,identify such roadways on the reclamation map and provide details on permanent road and ditch line
stabilization.
The main haul road and service roads will remain for vehicular access to the lake formed by the
pit. These roads shall be stabilized while the quarry is active. Other roads to remain will be
determined by the future use of the site after operations have ceased.
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.
No off-site generated waste requiring a NC DEQ Solid Waste permit will be allowed on-site.
Clean used concrete will be accepted and stored for processing and resale. This material will be
stored in areas with approved erosion control measures, as applicable. Waste products
generated through typical quarrying activities(i.e. scrap metal, cables,drill steel, etc.)may be
disposed on-site in a designated area but will typically be removed by a local scrap metal dealer.
All other waste products such as batteries, used oil,junked equipment, etc.will be recycled
and/or disposed of off-site by private collection firms.

Description
Hydrologic soil groups are based on estimates of runoff potential. Solis are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet,and receive
precipitation from long-duration storms.
The soils In the United States are assigned to four groups(A, B, C, and D)and
three dual classes(A/D,B/D,and C/D).The groups are defined as follows:
Group A. Soils having a high infiltration rate(low runoff potential)when
thoroughly wet.These consist mainly of deep,well drained to excessively
drained sands or gravelly sands.These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet.These
consist chiefly of moderately deep or deep,moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet.These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture.These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate(high runoff potential)when
thoroughly wet.These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table,soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly Impervious
material.These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group(A/D, B/D, or C/D),the first letter is
for drained areas and the second is for undralned areas. Only the soils that in
their natural condition are In group D are assigned to dual classes.
