Subject: Revised Permit Modification Application for Buechel Stone Corporation
Steel Gray Mine, Spruce Pine, North Carolina
Dear Mr. Parr,
In response to the December 19, 2022 letter from the North Carolina Department of Environmental Quality
(NCDEQ)commenting on the October 25,2022 Permit Modification Application for the Buechel Stone
Corporation (BSC)Steel Gray Mine(Mining Permit No. 61-19), near Spruce Pine, North Carolina,Arcadis US,
Inc. (Arcadis), is submitting the attached revised modification application and supporting materials on behalf of
BSC. The application is being submitted pursuant to G.S. 74-52 of the Mining Act of 1971 for review and
approval by NCDEQ. The mine is owned and operated by Buechel Stone Corporation (BSC).
The attached application is a revision to the October 25,2022 permit modification issued by NCDEQ and is
intended to address conditions required in the NCDEQ's December 19 letter. Specifically,thee include the
following:
1. Please provide construction and maintenance details for all outfalls.
Response: Construction and maintenance details are provided on Figure 10 of the attached package.
Note that the revised stormwater and sedimentation control system includes only one outfall, Outfall 01.
2. Please provide construction and maintenance details for conveyance system(diversion ditches, berms,
etc.) to convey stormwater or mine dewatering, etc., water from the drainage areas to the traps and
from the traps to the outfalls. Please clearly indicate and label on the map any conveyance system on
the mine map. These details, which are shown on the NOI maps for the stormwater permit, need to be
included on the mine map.
Response: Construction and maintenance details are provided on Figures 9 and 10 of the attached
package.
3. Please provide dimensions and calculation for the newly proposed unlabeled traps.
Response: The dimensions of the sediment traps are shown on Figure 9 and provided in Attachment 2

4. Please clarify if traps T-1A and T-2 were enlarged or installed in an arrangement not previously
approved. Please provide any calculations and dimensions for modifications to previously approved
traps.
Response: Traps T-1A and T-2 are no longer part of the sedimentation control system. It has been
replaced with the above-described system.
BSC acknowledges that pumping of groundwater will be required to mine a portion of the rock. However, pumping
activities will be temporary and likely to end after approximately one month. A pumping plan is provided in
Attachment 3 of the application package. Groundwater will be pumped over the haul road in basin DA-1. Overflow
from basin DA-1 subsequently discharges through Channel C-1 into the Main Basin. Water that accumulates in the
Main Basin ultimately discharges to Outfall 01 through a skimmer dewatering device described on Figure 10. The
Main Basin is also equipped with an emergency spillway as shown on Figures 9 and 10.
There will be no change to the total permitted acreage(60.90 acres). The proposed mine area remains
approximately 0.70-acre area with an estimated site life of 10 years. Furthermore, per your October 13, 2022
email, adjacent landowner notification is not required for this modification application.
The enclosed package includes one original and five copies of the modification application, attachments, and
figures.
Please contact me with any questions. Thank you for your consideration.

Revised July 13, 2021 P a g e 17

Response to Item 3C of Permit Modification Application
The withdrawal of groundwater is temporary and intermittent until mining can be
completed in the low areas of the quarry and is expected to stop after 1 month of
dewatering. Typically, the water in the pit is pumped for approximately 8 hours per day,
thus assuming a pumping rate of 200 gallons/minute, approximately 100,000 gallons
would be pumped during the course of a day. This will be modified depending on the
change in water levels during the day—i.e., less water may be pumped if the water level
decreases faster than expected. The Pumping Plan contained in Attachment 3
provides additional detail on the groundwater pumping.
Two residential wells are located within 500 feet of the area where dewatering is
occurring. Logs were not available for these wells— North Carolina did not require
private well logs before 2008, but industrial and commercial wells in the area are greater
than 200 ft deep. Because the excavation is just below the water table, it will only affect
the shallow groundwater in the immediate vicinity and will have no impact on the wells.
The mine locale is served by private wells.

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 wide 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).
A minimum buffer of 25 ft will be maintained but the buffer may be larger in
certain areas of the site. Buffers are shown on Figures 2, 3, 4, 5, and 6.
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).
A 50 ft minimum buffer will be observed along the North Toe River and unnamed
tributary to the east as shown on Figures 2, 3, and 5.
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.
Mining will be.performed using the bench method for safety, access, and to
reduce slope Instability thus preventing slides and the associated dangers.
Proper sloping of all waste rock material will be observed. Final slopes in
reclaimed areas will be 3H:1 V or less. Reclamation topoggraphy for the
previously mined area is shown on Figure 5 and reclamafon topgraphy for the
area to be mined is shown on Figure 6.

Buechel Stone — Steel Gray Mine
Spruce Pine, North Carolina
Permit Application Item C.1 Mining sequence
15`year:
In year one for this mine Buechel Stone Corporation (BSC) will fill in the deepest
area which currently holds several feet of water. By doing this we will avoid any
potential for encroachment into the water table.
Beginning from the west side of the area the mining will proceed to the east
approximately 50-100'. This will allow us to turn the face of the wall to the east
and avoid any fly rock concerns in the future.
Moving forward BSC will provide oversight to the blasting process to ensure
safety and efficiency.
Sedimentation ponds are planned at the two locations shown on Figures 3 and 4.
A Notice of Intent (NO[) to discharge stormwater from the site has been filed with
the North Carolina Department of Environmental Quality (NCDEQ). Stormwater
compliance requirements will be conducted with the help of third party
consultants.

Year 3:
By year 3 BSC will be mining in a northeast direction provided the rock material
stays true to the desired colors and quality. As the mine progresses reclamation
activities will continue in areas just previously mined to avoid potential
stormwater issues with the North Toe River located to the south.
At this point we will be approx. 20' down and 150' north east. There will be 1-2
different bench areas for diversity of material. The haul road to the North may
have to be rerouted as the quarry moves. We hope to have the demand for 300+
ton per month from this quarry.
Year 10:
By year 10, provided the rock material is still of acceptable quality BSC will
continue to quarry east-northeast toward the edge of the mine permitted area. At
that point BSC will consider whether to file a Permit Modification for additional
acreage. The haul road will be completely rerouted by now.

Pumping Plan

u
Buechel Stone — Steel Gray Mine
Basin Pumping Plan
Site Condition
Operations at the Steel Gray Mine are currently on hold pending a renewal of the facility Mine Permit.
During this time,the previously mined area at the base of the active face has filled with water.
Accumulated water is a combination of surface water runoff from precipitation as well as groundwater
recharge through fractures in the bedrock,with the majority of the water being from groundwater.
In order to complete mining in the area,water must be pumped out to allow for safe operations.To do
this in a manner compliant with applicable regulations established by Part G of the NCG02 permit,
comingled mine groundwater and surface runoff water must be pumped into and through the new
stormwater skimmer basin. Due to the changing volume of water present,sizing the skimmer basin for
dewatering activities is not possible.To address this,the following Pumping Operations and Monitoring
Plan has been prepared.
Pumping
The recently designed skimmer basin has an available storage volume of approximately 19,500 cubic
feet(cf)at the outfall weir elevation(INV=2550.60),and a total storage area of 29,595 cf to the top of
berm(Ele.=2552.00).The available storage volume of 19,500 cf exceeds the required storage capacity
of 12,500 cf(1,800 cu.ft./acre)established in Section 6.64 of the NCDEQ Erosion and Sediment Control
Manual.The following Pumping Operations and Monitoring Plan has been prepared in order to provide
guidance for dewatering of the active face area.
The pumping plan is as follows:
1. Verify pending weather conditions are absent any large-scale precipitation events. If any
stormwater events(greater than 1-inch)are anticipated in the next 24-hours, do not initiate
dewatering activities.
2. Verify current free board in the pond (i.e.top of water to overflow weir outfall elevation). If less
than 2 feet,do not initiate pumping.
3. If the criteria#1 and#2 are acceptable, pumping can be initiated.
a. Pumping should start at an approximate flow rate of 200 gpm.
b. Water from the mine pit will be pumped over the haul road (via hose) and into basin
DA-1 (see Figure 2)
c. If ponds are empty at the beginning of pumping,the available pumping time is
approximately 12 hours.
d. The discharge rate of the skimmer is approximately 0.066 cfs or approximately 30 gpm,
which will result in approximately 3.4 days to fully drain via the skimmer. Note that it is
not required to fully drain the basin prior to continuing to dewater.

\IWOI� 4. A record of the pumping events will be maintained on site. Records will include date,start
time,stop time,estimated water levels,and any precipitation events that occur during these
pumping events.
5. During pumping events,the pump/basin should be inspected every 2 hours at a minimum to
verify operation in accordance with this plan.

Blasting Plan

Blue Ridge Quarries, inc.,keel Gray Mine
Site Blast Program and Plan
Introduction:
To assure a safe and economical blast all applicable federal,state,and local regulations will be followed. Good
acceptable practices from non-regulatory agencies,such as Institute Makers of Explosives(IME),International Society of
Explosives Engineers(ISEE)will be followed.
This blast program and plan is to aid In assuring the security of explosives material where stored,transported,handled,
and used as well as the control of the blast process from design to initiation,evaluation and In handling of any
premature or misfire condition. A blast program and plan,when followed,will also aid in the assurance of safety to the
public,site personnel and surrounding properties.
As with any job, it is imperative to have a plan of action and to follow that plan. Ninety percent of a job's success or
failure Is attributable to prior planning. Proper blast planning can enhance safety by eliminating many hazards. A
blaster can calculate the elements of a blast to assure a safe and productive shot before putting any explosive in the
ground. A plan can help increase production and safety by allowing the blaster to see on paper what the shot Is planned
to do,and consequently, by allowing the blaster to make necessary adjustments where needed. In North Carolina the
Department of Environment, Health and Natural Resources requires mines and quarries to have an approved blast plan
prior to being issued a mining permit.Proper calculations for burden,spacing,borehole depth and size,timing between
holes and rows and pounds of explosive per delay, along with proper scale distance calculations, can help eliminate
excess vibration,air blast and flyrock.
Regulatory requirements:
• Bureau of Alcohol Tobacco and Fire Arms
• 30 CFR part 56 Mandatory Health and Safety Standards
• North Carolina Administrative Code,Chapter 6
• If explosives are transported on a public highway the 49 CFR requirements will apply

stringent requirement will apply.
• Biasthole: A hole drilled into material to be blasted,for the purpose of containing an explosive charge,also
called borehole or drill hole.
• Blast Pattern: The plan of the drill holes as laid out for blasting;an expression of the burden distance and the
spacing distance and their relationship to each other.
• Blast site: The area where explosive material Is handled during loading of blastholes..Including 50 feet in all
directions from the perimeter formed by loaded holes. This distance shall apply in all directions along the full
depth of the blasthole.
• Blaster or Blaster In charge: That qualified person In charge of,and responsible for,the loading and firing of a
blast. Sometimes referred to as a shot firer. Though more than one blaster can be part of a blast crew,there
can be only one blaster In charge for each blast site.
• Blast crew: A group of persons under the direction of the blaster In charge,and are properly trained meeting all
regulatory requirements necessary for handling explosives or related material,who assist the blaster in charge
In loading and firing a blast.

energy source to Initiate the detonating sequence to fire the blast.
• Burden: The distance from the blasthole and the nearest free face or the distance between blastholes measured
perpendicular. Also the total amount of material to be blasted by a given hole.
• Charged: A blasthole(borehole)containing a primer and explosive material awaiting firing.
• Coupling: The degree to which an explosive material fills the cross section of a blasthole.
• Detonator. Any device containing an initiating or primary explosive that is used for initiation detonation in
another explosive material.
• Drill log: A written record of information about a specific borehole,or blast pattern. The record shall contain
the minimum Information;hole depth,hole diameter,dimensions for the burden and spacing,number of holes
In a row and the number of rows in the blast pattern,any hole anomaly referenced by a measurement;such as
broken material,change in geology,water,cracks and or crevices,etc.and any other Information the blaster in
charge may need from the driller.
• Flyrock: Rocks propelled from the blast area by the force of an explosion.
• Free face: A surface exposed which provides room for expansion and movement of the burden being blasted.
• Ground vibration: Shaking the ground by elastic waves emanating from a blast;usually measured in inches per
second of particle velocity.

Use: To complete a safe blast,everyone Involved must be committed to sVee work practices and see that every step
of the operation is done in a manner which uses the correct methods and procedures. Shortcuts and carelessness is
never an option on a blast site.
• Review drill log: Prior to explosives being brought to the blast site the blaster In charge will review the drill log
and address any needs for corrections that would be necessary to assure a proper blast pattern and safe firing of
the explosives. This will be accomplished prior to the explosives being brought to the site.
Blast log(report): The Information on the blast log should paint a picture of the blast that would stand in a court of law.
The blast log is a required document for every shot no matter the amount of explosive material used. The minimum
Information shall be:
• Date,
• Time of blast,
• Blast site location,
• Location of all blastholes In relation to each other and the free face as well as directional movement of the total
burden in relation to geographical north(graphical representation),
• Weather at the time of blast,
• Distance and direction to the nearest inhabited off site structure,scale distance information used to calculate
amount of explosive fired within an 8 millisecond delay period,
• Seismograph information,
• Type of material blasted,
• Blast design(number of holes in a shot,burden spacing,depth,length and type of stemming,type of delay used,
Initiation method,explosives used in the shot and total weight of explosives to include the primer),
• Powder factor,
• Blasters name and signature,and
• Any unusual circumstances relative to the shot such as water in the blasthole or excess delay in firing.
• A graph of the shot pattern should be drawn to include the timing of each blasthole, delays within each
blasthole, placement of primer within the blasthole, any stemming used In the blasthole for decking purpose,
and stemming height used to cap each blasthole.
Survey the area: Before explosives are brought to the site,a check of the conditions at the blast site shall be conducted.
The high wall and ground conditions that pose any hazard must be addressed and taken care of prior to proceeding with
the blasting operation. At no time will a blast be loaded during the approach of an electrical,snow,or sand storm. If at
any time a storm approaches the blast area,all persons will be removed from the blast area and proper safe guards put
In place. The area will be properly posted and guarded until after the approaching storm. The explosive laden vehicle
will remain in the blast area and not used to transport persons from the area during the approach of such storm.
• Eliminate extraneous electricity sources: Watch for over head power lines,RF energy sources,approaching
electrical storms,blowing snow or sand and address those hazards in accordance with applicable regulations. 114�
5

• Explosive material and detonators must be kept separated at all times until loading of the blasthole begins.
• Security: Survey and determine all approaches to the blast area and properly provide safeguards. Remove
personnel not needed for the blasting operation from the area and to a safe location. Properly post the blast
site to warn others of the dangers.
• Extraneous material: Remove all unnecessary equipment,tools,etc.not required for the blasting operation to a
safe location. Drilling shall not be done within the blast site.
Borehole preparation: Check all boreholes prior to commencing loading the shot to assure proper depth and
contiguousness. A blasthole is never loaded immediately after drilling. The blaster must make assurances that the
temperature in the blasthole Is less than 150 degrees Fahrenheit.
Priming charge(primer): Primers are made only at the time of placing them within the blasthole.
• Preparing the primer. The detonator will be placed into the center of the explosive to be used.
• Securing: The detonator will be securely fastened to the explosive material so that it will not be pulled from the
explosive material when lowered into the blasthole.
• Priming charge location in the blasthole: The priming charge should be located in the blasthole pointing in the
direction of Initiation.
• Coupling: The blaster in charge must assure that when loading explosive material on and around the priming
charge blasthole coupling is maintained.
Loading: Once the primer is In place,the remaining explosive column is loaded. Care must be taken to not damage leg
wires,tubes,and cords during the loading process and that the primer is securely anchored. The primer shall never be
,,.�ubJected to forces such as dropping heavy cartridges on top of or tamping directly on the primer.
• Charging: Holes shall be loaded starting at the free face.
• Depth of charge: The blaster will assure the proper depth of the explosive charge as determined by the blast
design. The explosive column shall be measured continuously if bulk explosives are used.
• Stemming: Once the blasthole Is loaded a stemming column Is placed on top of the explosives to seal the
explosive column. The type of and depth of stemming will be determined by the blast design.
• Charged: Once a hole is loaded it is considered charged and ready for firing. Equipment is never driven over or
placed on a charged blasthole.
Connecting the shot: After all blasholes are charged,the detonators must be connected to form a circuit. Only persons
necessary for connecting the shot will remain In the blast area. It Is the responsibility of the blaster In charge to assure
all detonators are properly connected as Indicated by the blast design.
• Electrical initiation: Only proper equipment will be used to check an electrical Initiation system. Regulatory and
detonator manufacturer requirements for checking electrical Initiation systems will be followed.
• Non electrical initiation: The blaster in charge will walk the shot and visually check all connections.
Seismograph set up: A competent person must perform a preblast survey at the nearest,offsite,Inhabited dwelling,as a
minimum prior to a blast event. A postblast survey should follow. Any complaints from the community will be
investigated immediately by the blaster in charge. A competent person must properly setup and operate a seismograph
for each blast. A seismograph Is used to monitor,record,analyze,and display ground vibrations and airblast resulting
`,✓from a blast. The seismic wave is measured from one point to another. The Information gathered from a seismograph
6

reading can aid the blaster In determining whether the explosive energy waste to do the work as designed. Excess
airblast and ground vibrations can be a nuisance to offsite persons resulting in complaints. In rare events damage to
structures can result from excess ground vibration and airblast.
• Seismograph: Must be maintained In accordance with the manufacturer recommendations
• Setup: In most cases a seismograph is setup at the nearest offsite and Inhabited dwelling. Follow the
manufacturer's recommendations for proper set up.
• Qualifications of operator. The operator of the seismograph must be properly tasked trained in the use of the
seismograph unit and familiar with the manufacturers operating procedures.
Firing: After loading and checking the initiation system,the blast shall be fired as soon as safely possible.
• Blast area security: Flyrock is one of the three leading causes of injury and death relative to a blast. The blaster
In charge must assure the blast area is sufficient,clear of persons,and all approaches are properly posted and
guarded.
• Blaster protection: The blaster In charge must assure the one qualified to fire the shot has adequate protection
(shelter)from all energy sources related to the blast.
• Audible warning: An audible warning must be given prior to firing. The warning signals will be posted in
conspicuous places for all In,or near,the blast area to familiarize themselves with the warning. The audible
warning must be distinguishable and heard above the surrounding noise level. Car horns are not to be used as
an audible warning. Hand signals can be used in conjunction with an audible warning. All people within the
vicinity of the blast area must be familiar with the warning signals prior to firing the shot. The audible signal
shall consist of a minimum of: A five minute warning prior to the blast signal;A blast signal containing a series of
short sounds 1 minute prior to firing;An all clear signal of a prolonged sound,Initiated by the blaster in charge,
following the post blast examination of the blast area by a qualified and competent person(s)to recognize all
hazards that could have been caused by the blast.
• Post blast exam: A qualified and competent person(s)will make a check of the blast area after sufficient time
has elapsed for all fumes,and dusts to settle. Na misfire is suspected the blaster in charge will establish a time
to allow for any burning charges,etc.to elapse. As a minimum the MSHA regulatory requirement for time will
be followed.
Misfires:
Any time an explosive does not detonate as planned,a misfire has occurred. It Is usually obvious when none or a
portion of a blast did not fire as planned. Sometimes partial initiation occurs within the blasthole and It is not noticed
until mucking starts. All misfires must be investigated because there is a reason for its occurrence. Ninety nine percent
of all misfires are due to human error. One percent can be attributed to product failure. The best way to handle a
misfire Is not to have one by following all acceptable practices during the loading and firing of the blast. First and
foremost,once a misfire is suspected,proper safe guards must be put Into place for the protection of persons in or near
the area.
Handling misfires: When a misfire occurs,everyone in the area Is at risk. The blaster In charge Is responsible for proper
handling of the misfire condition. Management should be notified immediately of a misfire condition. Each misfire
occurrence is unique. The following are recommendations for handling a misfire situation:
1. The blaster In charge shall invoke sufficient safeguards to exclude all persons from the potential blast area.
7

2. No work shall be done except that necessary to remove the hazard o�e misfire. Only those necessary to do
the work shall enter the potential blast area. Only the blaster in charge and the absolute minimum competent
persons needed to assist in handling the misfire will be allowed to approach the misfire.
3. The blaster in charge shall determine the safest steps for removing the hazard of the misfire. During the
development and implementing these steps,the blaster in charge shall comply with all applicable regulations,
and the manufacturers recommendations. Further,the guidelines from the IME will be utilized.
4. Regulations governing the waiting periods before approaching a misfire will be adhered to.
S. No drilling,digging,or picking shall be permitted until all misfires have been detonated or the blaster In charge
approves the work.
Flyrock: The primary means of controlling flyrock Is through proper blast design and delay timing. Proper confinement
within the blasthole is also essential for controlling flyrock. Anytime flyrock has traveled beyond the blast area the
blaster in charge must investigate the cause and take any corrective actions In the future to prevent a recurrence.
Excess flyrock,that flyrock thrown beyond the blast area,may need to be reported to federal,state,and local
authorities. It is the responsibility of the blaster in charge to report to the proper authority a flyrock incident.

Practice Applies vegetation,particularly slopes steeper than 3:1.
Planning Rough slope surfaces are preferred because they aid the establishment of vegeta.
Considerations Lion,improve water infiltration,and decrease runoff velocity.Graded areas with
smooth,hard surfaces may be initially attractive,but such surfaces increase the
potential for erosion.A rough,loose soil surface gives a mulching effect that
protects lime,fertilizer,and seed.Nicks in the surface are cooler and provide
more favorable moisture conditions than hard,smooth surfaces;this aids seed
germination.
There are different methods for achieving a roughened soil surface on a slope,
and'the selection of an appropriate method depends upon the type of slope.
Roughening methods include stair-step grading,grooving,(Figure 6.03a).and
tracking.Factors to be considered in choosing a method are slope steepness,
mowing requirements,and whether the slope is formed by cutting or filling.

Design Criteria No formal design is required.
Construction CUT SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED
Specifications Stair-step grade or groove cut slopes with a gradient steeper than 3:1(Figures
6.03b and 6.03c).
Use stair-step grading on any erodible material soft enough to be ripped with a
bulldozer. Slopes consisting of soft rock with some subsoil are particularly
suited to stair-step grading.
Make the vertical cut distance less than the horizontal distance, and slightly
slope the horizontal position of the"step"in toward the vertical wall.
Do not make individual vertical cuts more than 2 feet in soft materials or more
than 3 feet in rocky materials.
Grooving uses machinery to create a series of ridges and depressions that run
across the slope(on the contour).
Groove using any appropriate implement that can be safely operated on the
slope,such as disks,tillers,spring harrows,or the teeth on a front-end loader
bucket.Do not make such grooves less than•3 inches deep nor more than 15 in-
ches apart.
fir✓ FILL SLOPE ROUGHENING FOR AREAS NOT TO BE MOWED
Place fill slopes with a gradient steeper than 3:1 in lifts not to exceed 9 inches,
and make sure each lift is properly compacted.Ensure that the face of the slope
consists of loose, uncompacted fill 4 to 6 inches deep. Use grooving, as
described above,to roughen the face of the slopes,if necessary.
Do not blade or scrape the final slope face.
CUTS,FILLS,AND GRADED AREAS THAT WILL BE MOWED
Make mowed slopes no steeper than 3:1..
Roughen these alias to shallow grooves by normal tilling,disking.harrowing,
• of use of culdpacker-seeder.Make the final pass of any such tillage implement

Make grooves formed by such implemeats close together(less than 10 inches)
and not less than I inch deep.
Excessive roughness is undesirable where mowing is planned.
ROUGHENING WITH TRACKED MACHMRY
Limit roughening with hacked machinery to sandy soils to avoid undue com-

Rare, Threated, and Endangered Species Habitat Review
Buechel Stone Corporation—Steel Gray Mine, Spruce Pine, North Carolina
This Rare, Threatened, and Endangered Species (RTE) Memo summarizes the results of a habitat
assessment for RTE species conducted on February 25, 2022, by Arcadis G&M of North Carolina, Inc.
(Arcadis) on behalf of Buechel Stone Corporation (Buechel) for the Steel Gray Mine Permit Modification
Application Project(Project)in Spruce Pine, Mitchell County, North Carolina(Attachment 1, Figure 1). The
survey was focused on an approximate 12-acre area north of Altapass Highway(Attachment 1, Figure 1).
The purpose of this delineation was to assess the presence or absence of potential RTE habitat that may
be impacted by the proposed Project. The habitat assessment was completed in response to the December
21, 2021 request from the North Carolina Department of Environmental Quality (NCDEQ).
BACKGROUND INFORMAIION
Prior to conducting the Habitat Assessment, Arcadis reviewed the following resources to identify the
potential locations and extent of caves and portals within the Project area:
• United States Geological Survey(USGS)topographic map, Spruce Pine, NC(USGS, 1994).
• Aerial Photography(Google Earth,2022).
The USGS topographic data, which identify intermittent and perennial streams, do not show mapped
streams north of the North Toe River within the environmental survey area.

MEMO
A review of 2022 aerial photography (Google Earth, 2022) of the Project area (Attachment 1, Figure 1)
shows that the surrounding land use is predominantly rural residential and agricultural with the survey area
being an active stone mine.
METHODOLOGY AND SURVEY RESULTS
Vegetative Communities
The environmental survey area comprises early to mid-successional forest and a floodplain field within an
existing stone mine.While most of the mined areas are cleared,the early to mid-successional forest canopy
community was dominated by sycamore (Platanus occidentalis), white oak (Quercus alba), sweetgum
(Liquidambar styraciNua), eastern hemlock (Tsuga canadensis), and red maple (Acer rubrum). Forest
understory was dominated by fescue (Festuca sp.), broomsedge (Andropogon virginicus), blackberry
(Rubes argutus), and goldenrod (Solidago canadensis). Representative photographs of the mine and
vegetative communities are included in Attachment 3. Locations of the photographs are shown on
Attachment 1, Figure 1.
RTE Species
Comment letters received from the U.S. Fish and Wildlife Service(USFWS)and NCDEQ indicated that two
of the RTE species with the potential to occur in the County would require a habitat assessment to determine
if there is a potential for these species to occur within the Project area. The NCDEQ stated that the
assessment should be conducted for the gray bat(Myotis grisescens-Endangered and Appalachian elktoe
(Alasmidonta raveneliana)-Endangered) (Attachment 2).
The gray bat roosts and hibernates in caves and portals that have specific temperature requirements
depending on the time of year. Caves are often deep and include large underground rooms. Based on the
site topography and soil types, one would not expect to find suitable winter or summer roosting habitat for
the gray bat in the Project area. No openings, passages, or other entrances to underground voids were
observed during the habitat assessment, confirming the lack of suitable habitat. Because of the lack of
habitat and that the site is an active stone mine that utilized blasting, the Project will have no effect on the
gray bat.
The Appalachian elktoe is mussel species that prefers relatively shallow, medium-sized creeks and rivers
with cool,well-oxygenated and moderate-to fast-flowing water. It has been observed in a variety of substrate
types including gravel mixed with cobble and boulders; in cracks in bedrock; and occasionally in relatively
silt-free, coarse sand. No streams or rivers are located in the proposed Project area, therefore activities
conducted at this site would have no effect on the Appalachian elktoe.
CONCLUSION
This memo summarizes the results of a RTE habitat assessment review conducted by Arcadis within the
environmental survey area at the Steel Gray Mine in Spruce Pine, North Carolina, on February 25, 2022.
Arcadis did not identify suitable habitat for the gray bat or the Appalachian elktoe withing the proposed
Project area,therefore the Project will have no effect on these species.
