Per NCDEQ review comments dated December 21, 2021 for the subject project, CEC is providing the
following responses. Each comment is listed below and responses are in Italic.
1. Please label and clearly indicate on the mine map the location of wells of adjacent properties.
Response: CEC contacted Forsyth County Health Department and requested any well
location information they had on all adjoining properties to the subject site. Two well permits
were located, 4901 Kesler Mill Road & 4880 Kesler Mill Road, these approximate well
locations have been added to Sheet C003 2021 Mine Map. (See attached well permits per the
attached investigation report by Highlands Environmental Solutions (HES), Inc. dated
February 1, 2022, HES contacted the Winston Salem Public Utilities Department (WSPUD)
to confirm or deny if any of the adjoiner properties had public water billing records. WSPUD
confirmed that water billing records were associated with 4952 and 4958 Kesler Mill Road,
properties on Kesler Mill CT, and all properties South and East ofKester Mill Court,
therefor these properties do not have drinking water wells on the property
2. Please provide a Pumping Operation and Maintenance plan for the pit dewatering.
Response: During initial dewatering of the existing pit, a floating pump will remove water
from the lake surface and discharge it through the existing 24-inch pipe directly to Silas
Creek. As this is a NCG02 permitted outfall, Vulcan will continue to monitor for NCG02
compliance parameters until the existing quarry is dewatered. Subsequently and before
filling activities commence, a sediment sump and final polishing system pond will be
installed. The pit will be dewatered by a floating pump located in the proposed sediment
sump. All groundwater & stormwater run-off will be diverted to the sediment sump then
pumped to the proposed polishing basin before discharging into Silas Creek. The pump will
be protected with rock inlet protection. Inlet protection will be cleaned of sediment once
sediment has reached a depth of 6" above original sump bottom. See Phase 2 Construction
Sequence and the labels shown on the mine map on Sheet C301.

3. Please provide information on how the pit dewatering will influence local groundwater table
and/or Silas Creek.
Response: Refer to the attached investigation report by Highlands Environmental Solutions,
Inc. dated February 1, 2022 for response.
4. The Division of Water Resources Groundwater Management does not have enough
information to complete their review on the application. Please provide additional
information on volume and method of dewatering. If pumping more than 100,000 gallons per
day you will need to register the water withdrawals with DWR and report on an annual basis.
If pumping more than 100,000, please provide proof of registration.
Response: At this time, Vulcan is proposing to pump less than 100, 000 gallons per day
during the dewatering process. If plans change and operations require pumping more than
100, 000 gallons per day, Vulcan will provide proof of registrations for water withdrawals
and report on an annual bases.
The proposed method of dewatering are as follows:
The initial pit dewatering will be provided with a floating pump, discharging directly into
Silas Creek. Once the pit is dewatered and Vulcan is able to construct the sediment pit, any
additional groundwater/stormwater runoff will be diverted to the sediment sump within the
pit. As stormwater fills the sump it will be pumped to the 18 " diameter RCP culvert which
then discharges into a second method of cleaning, the proposed polishing basin. The pit
discharge will be controlled by the floating pump inside the sediment sump.
5. Please provide supporting calculations to confirm that the polishing basin is adequately sized
for the 25-year storm event.
Response:
The polishing basin will not be affected by a 25 year storm event as the basin is only
receiving pumped flow from the pit sediment sump. All surface flow will be diverted around
the polishing basin therefore the basin will only receive stormwater that falls directly into the
basin. Vulcan will drain the pit sediment sump after storm events via the floating pump
system to the final polishing basin (See below sequence for pit sediment sump and polishing
basin).
The proposed sequence of events for stormwater collection and release for erosion control
purposes are as follows:
Stormwater runoff inside the pit is diverted through one of the two diversion ditch's above
the sump. Stormwater then travels through the diversion's and outfalls to an 18" diameter
HDPE Slope drain. The flow then moves through the slope drain and outfalls onto a rip rap
apron at the bottom of the sump. Once inside the sump the water will be stored and flow
through one (1) 2'-high rock baffle before entering the pump chamber. Stormwater will be
stored in the sump until water reaches 2ft above bottom of the sump in the pump chamber.
Once the 2ft storage height is reached pumping operations will begin and pit water will be

discharged. Clean stormwater will be pumped to an 18 " diameter RCP culvert which then
discharges onto a rip rap apron into a second method of cleaning, the proposed polishing
pond. The discharged stormwater will then flow through two (2) 2'-high rock baffle's to the
skimmer chamber. Vulcan will then control the discharge of the polishing basin by moving
the skimmer off the 2ft-high rip rap pad to allow stormwater to discharge. No surface
stormwater will enter the polishing basin, a clean -water diversion ditch has been provided
around the polishing pond to ensure no surface run-off enters the polishing pond.
b. The polishing basin appears to utilize rock baffles; please confirm that their volume is not
included in the figures for volume provided.
Response: See response to comment No. 5. The rock baffles are not included in the volume
calculations for the sediment sump nor the polishing basin. (Refer to Polishing Basin
calculations)
7. Maintenance notes provided appear to be for coir baffles, please provide a maintenance plan
for the rock baffles.
Response: Maintenance Plan has been updated to reflect the use of rock baffles. See Detail 9
on Sheet C801 for updated maintenance plan.
8. Please clearly identify and label on the mine map the location for temporary stockpiling,
contractor laydown, and parking. Please clarify the erosion and sediment control measures
with construction and maintenance details for each of these areas.
Response: There will be no temporary stockpiling or contractor laydown area required for
this project. Proposed erosion control devices have been provided on Sheet C003, 2021 Mine
Map which includes silt fence, polishing basin, construction entrance, stone access road with
pull ofj`'area, inlet/outlet protection etc. It is anticipated that two people would be at the site
atone time during the filling operation. Adequate and safe parking for employee vehicles
during the day and grading equipment at night is provided outside of the pit area in the stone
pull out area. If additional employee%onstruction parking is required, the parking will be
provided off -site. The above ground storage tank has been added to the various sheets
comprising the 2021 Mine Map. The above ground storage tank construction detail and
design data are provided on Sheet C802.
9. The construction entrance appears to be inadequate. Please provide a construction entrance of
at least 100' or clarify why a construction entrance of less is adequate.
Response: The construction entrance detail, Detail I Sheet C800 has been updated to
indicate a minimum length of 100 feet. The construction entrance call -out on Sheet C300 has
also been updated to include a minimum 100 foot length.
10. Please clarify exactly what material will be used for fill. Please define "other naturally
occurring materials" as stated in the application. Please clarify if any of the material entering
the site will have been chemically treated.
Civil & Environmental Consultants. Inc.

NCDEQ
CEC Project 314-511
Page 4
February 11, 2022
Response: The materials used in the fill placement will be materials that are generated
during the development of other Vulcan mine sites such as topsoil, overburden, and
unsaleable rock, excavated sediment, fines created by crushing process, etc. The materials
will not include any materials that have been created by other producers such as recycled
asphalt products, crushed concrete, byproducts from the creation of concrete or materials
from another public or private construction project. The fill material will also not include
any tree debris or LCID materials.
The materials are not chemically treated. Some of the settled fines come from water that may
include polymers that were used in the collection process to encourage settling. Only
polymers that are approved for use in compliance with the NPDES permits are used in
Vulcan quarries.
11. Please provide the locations where fill material will be coming from. Please clarify how
reporting of future locations and volumes will be monitored.
Response: The fill material will be coming from Vulcan's current and future quarries in the
region. The initial locations are North Quarry, East Forsyth, and Smith Grove. We will
provide notice prior to accepting material from additional VMC locations. The project is
designed to fill the existing quarry as part of a reclamation process, which is limited to the
capacity of the existing pit. The materials being used for the project are not a hazardous
waste, so reports concerning the volume and location of placement are not required. Lastly,
due to the scheduling, weather, and other delays, it is difficult to estimate what volume may
be expected from any of the listed quarry sites during any given time period. The intent is to
use the US 421 Quarry to accept this inert material on an as needed basis. As the volume of
material that can be moved to this site is limited by the depth of the current quarry pit, how
much material is moved per month or year does not appear to be relevant.
12. Please provide soils information from the locations where the material will be coming from
and how pH will be monitored on the material entering the site.
Response: Refer to the attached investigation report by Highlands Environmental Solutions,
Inc. dated February 1, 2022 for response.
13. Please provide pH information on the soil and rock of the receiving site.
Response: Refer to the attached investigation report by Highlands Environmental Solutions,
Inc. dated February 1, 2022 for response.
14. Please clarify how potential groundwater infiltration will be addressed.
Response: Refer to the attached investigation report by Highlands Environmental Solutions,

15. Please clarify your testing and reporting procedures to achieve compaction to a minimum of
90% standard proctor. At a minimum, details should include testing method, testing
frequency, sampling area, and lift size.
Response: This project consists of the dewatering/filling of an existing closed mine pit. The
reclamation of this pit is for a vegetated natural area for wildlife and not for construction
purposes as a structural fill. As such, engineered compaction of the fill material is not
warranted. As noted above, all fill material will be contained within natural rock walls,
preventing lateral movement of the fill in any direction. Also, differential settlement should
not be a concern. The fill material will receive some degree of compaction as it is driven
over dumped by Vulcan dump trucks and tracked in by a bull dozer as it is graded into place
during each lift of fill placement — See Sheet C306 for more details and a description of fill
placement and stabilization. Thus, compaction of the material will be for erosion purposes
only, not for structural fill purposes.
Should you have any questions or require any additional information in support of this review please
do not hesitate to contact us at 980-237-0373.

Subject: Response to NCDEQ Request for Information
421 Quarry Mine Permit Modification
HES Project #11131
Dear Mr. Johnson:
Highlands Environmental Solutions, Inc. (HES) is submitting this correspondence regarding our review of
correspondence from the North Carolina Department of Environmental Quality — Division of Energy,
Mineral, and Land Resources (NCDEQ) regarding modification of Mine Permit #34-01. The subject permit
is for the Vulcan Materials Company (VMC) 421 Quarry, which is currently an inactive operation. It is our
understanding that VMC intends to modify the Mine Permit to allow for the former quarry pit to be dewatered,
and the former quarry pit be used for the storage of inert mining by-products, such as overburden, fines,
unusable rock, and other inert materials generated by VMC's permitted mining operation without chemical
treatment. The location of the 421 Quarry is depicted on Figure 1 and Figure 2, included in Attachment
A.
In correspondence dated December 21, 2021 (included in Attachment B), the NCDEQ requested
additional Information regarding VMC's request for Mine Permit modification. A copy of the correspondence
is included in Attachment B. Specifically, HES was requested to investigate and address items #3, #12,
#13, and #14 in this correspondence. HES' responses to these items are presented below:
#3: Please provide information on how pit dawatering will influence local groundwater table and/or Silas
Creek.
On January 26, 2022, HES personnel visited the site, which included an inspection of the pit (including
exposed stratigraphy) and inspection of Silas Creek. Within the quarry pit, both bedrock and
unconsolidated overburden were observed. Saturated soils (i.e., water table aquifer) were not observed
above the bedrock within the pit. Two small fracture areas within the exposed bedrock were observed
discharging a small volume of groundwater along the Southeastern and Southern wall of the quarry pit.
Select photographs of the site are included in Attachment C.
Multiple residential properties are located within 1700 feet of the quarry pit, with the closest residence being
situated approximately 795 feet South of the quarry pit, and on the opposite side of Silas Creek from the
quarry pit. The locations of these residences are depicted on Figure 3. Residences to the North of US
Highway 421 are located in areas where HES observed both fire hydrants and water meters; as such it is
concluded that these areas are connected to public water. HES was uncertain 9 residences along Kester

Mr. Tony .lonson February 1.2022
Response to NCDEQ Correspondence — Mine Permit #34-01 Page 2
Mill Road or Kester Mill Court were connected to public water. HES contacted the Winston Salem Utilities
Department to see if billing records were available for properties located along these two roads to confirm
(or deny) if these properties were connected to public water. Three addresses (4880, 4952, and 4958)
were located on Kester Mill Road. The WSPUD confirmed that water billing records were associated with
4952 and 4958 Kester Mill Road, but not for 4880 Kester Mill Road. it is reasonable to suspect that the
property at 4880 Kester Mill Road utilizes a water supply well for potable water.
Per the WSPUD, water billing records were available for all properties along Kester Mill Court, and in areas
South and East of this area.
Based on this information, HES concludes that all nearby residences are connected to public water, with
the exception of the residence at 4880 Kester Mill Road. Assuming this residence uses a water supply
well for potable water, this residence is located approximately 790 feet South -Southwest of the quarry pit,
and on the opposite side of Silas Creek. Silas Creek serves as an assumed groundwater flow boundary
between the quarry pit and this assumed water supply well. Additionally, potable water is available to this
landowner, if needed. The total depth of the quarry pit is 50 feet. Most water supply wells installed in the
Piedmont Physiographic Province are drilled to several hundred feet in depth. As such, HES concludes
that dewatering of the former quarry pit will have no effect on the water table aquifer, only minimal effect on
the groundwater in the bedrock aquifer, and no effect on the water supply well assumed to be present at
4880 Kester Mill Road.
Silas Creek is an actively flowing, ephemeral stream. The quarry pit does not continuously or naturally
contribute discharge to this surface water body. Water Is only discharged from the quarry pit to Silas Creek
when VMC conducts discharge activities from the quarry pit to Silas Creek. HES personnel conducted
reconnaissance of the quarry pit and along Silas Creek both upstream and downstream of the subject
property. Neither springs nor other areas of groundwater discharge to Silas Creek were observed. The
water level in the quarry pit is below the level of the interface between the soil overburden and the bedrock.
As such, water in the quarry pit does not contribute to the unconsolidated (or water table) aquifer local to
the area.
During the initial dewatering of the former quarry pit, flow will be increased in Silas Creek. VMC will install
structures and discharge at a flow rate such as not to cause flooding conditions downgradient and/or
excessive erosion within Silas Creek. Once the pit Is dewatered, the water discharge rate from the pit will
be reduced, since water discharge will only occur to maintain the dewatered condition. This will reduce the
flow within Silas Creek due to dewatering operations.
Based on the information presented above, HES concludes that dewatering of the quarry pit will not
influence the surficial aquifer, or significantly influence the bedrock aquifer. Additionally, there is no
evidence to suggest dewatering of the quarry pit will influence surface water flow within Silas Creek.
#12: Please provide soils information from the locations where the material will be coming and how pH will
be monitored on the material entering the site.
VMC intends to transport and store inert mining by-products, such as overburden, fines, unusable rock, and
other inert materials generated by VMC's permitted mining operation without chemical treatment. These
materials will be generated at several local VMC quarries in the area, where igneous and metamorphic rock
are crushed and washed after mining. Igneous and metamorphic rocks are typically slightly acidic, therefore
it is reasonable to assume the pH of these materials would be expected to be slightly acidic, given the
geochemistry of these and the parent materials. On January 26, 2022, HES collected a sample of the fine-
grained material from the current material storage area located at the VMC North Quarry facility, and tested
pH of this material with values of 5.5 being detected. With regards to the material entering the site, it is our
understanding that incoming material will predominantly be the unusable fine-grained material.
During the site visit on January 26, 2022, HES also tested the pH of the surface water in Silas Creek and
in the quarry pit. The pH of the surface water in Silas Creek was evaluated upgradient and downgradient

Mr. Tony Jonson February 1, 2022
Response to NCDgQ Correspondence — Mine Permit #34-01 Page 3
of the former quarry pit, with values ranging from 5.0 to 5.5. The pH of the water in the quarry pit was also
found to be 5.5.
Fine-grained wash material from the crushing of limestone or sedimentary rock (which could raise the pH
of the material and any runoff) will not be transported to the site for storage. Only material from VMC
facilities in the North -central and Northwestern portions of North Carolina will be used. All of these areas
contain acidic bedrock. Because the incoming material will be generally consistent with the pH found at
the receiving 421 quarry site, the monitoring of the pH of incoming materials should not be required.
#13. Please provide pH information on the soil and rock of the receiving site.
Based on information obtained from the Geologic Map of North Carolina (1985), the bedrock underlying the
subject site consists of metamorphosed igneous rock (metagabbro, metadiorite, amphibolite, etc.). The
pH of the bedrock would be expected to be slightly acidic. Testing of the fine-grained materials during this
investigation confirmed this as provided in the response above.
Per the United States Department of Agriculture (USDA) Web Soil Survey (WSS), soils in the area consist
of Fairview Sandy Loam and Fairview Clay Loam. These soils are derived from the weathering of granite,
schist, and/or gneiss bedrock. Based on information from the WSS, the pH of Fairview soils varies from
5.5 to 7.0, with an average of 6.08. Soil pH values are generally consistent with the pH of the fine-grained
materials that were tested at VMC's North Quarry source site and at the 421 Quarry receiving site, as well
as the pH of surface water measured in Silas Creek. A copy of the data obtained from the WSS is included
in Attachment D.
#14: Please clarify how potential groundwater infiltration will be addressed.
Based on information provided by VMC, the former quarry pit will be continuously dewatered. As such,
significant groundwater infiltration is not anticipated. Since the material that will be stored in the former
quarry pit is of a similar geochemical nature to the existing soil, bedrock, and groundwater, the potential
infiltration of groundwater (if it occurs), should not be of an environmental concern.
HES was requested to investigate and provide input regarding four comments/questions in correspondence
from the NCDEQ to VMC with regards to the modification of Mine Permit #34-01. Based on the results of
our Investigation, HES concludes the following:
• Dewatering operations in the VMC 421 Quarry will not adversely impact baseflow within Silas Creek
nor water levels in the public water supply well located across Silas Creek, an assumed
groundwater flow boundary.
• Dewatering operations in the VMC 421 Quarry will not impact groundwater in the surficial aquifer.
The depth of the former quarry pit is relatively shallow (50 feet), as such dewatering of the former
quarry pit will only minimally influence groundwater conditions (i.e., water levels) in the bedrock
aquifer.
• VMC intends to install a pump to continuously dewater the former quarry pit. As such, a significant
volume of groundwater will not be present to infiltrate within the former quarry pit.
• The storage of the intended material within the former quarry pit will not adversely impact
groundwater quality in the event that limited groundwater infiltration occurs.
• The storage of the intended material and discharge of water from the former quarry pit will not
adversely impact water quality within Silas Creek.

Description
Soil reaction is a measure of acidity or alkalinity. It is important in selecting crops
and other plants, in evaluating soil amendments for fertility and stabilization, and
in determining the risk of corrosion. In general, soils that are either highly alkaline
or highly acid are likely to be very corrosive to steel. The most common soil
laboratory measurement of pH is the 1:1 water method. A crushed soil sample is
mixed with an equal amount of water, and a measurement is made of the
suspension.
For each soil layer, this attribute is actually recorded as three separate values in
the database. A low value and a high value indicate the range of this attribute for
the soil component. A "representative" value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.
