7.1 Use the space below to expand upon any of the above items. Use this space to provide any information you believe the
reviewer should consider in establishing permit limitations.Attach additional sheets as needed.
c Samples in Section 4 reflect expected discharge quality;the samples were taken from the Pit Lake,not the outfall point.
Water quality of the discharge water contained within Pit Lake does not exceed Class C aquatic water standards(See
E Engineering Alternative Analysis Attachment).The attached Kings Creek Stability and Water Quality Assessment
`o
c demonstrates that minor increases in flow due to the mine pit dewatering is not expected to adversely impact the
banks of Kings Creek,and is not expected increase flood or adversely effect elevations beyond the subject property
lines. Based on the attached Engineering Alternatives Analysis,direct discharge to Kings Creek is deemed the most
environmentally sound alternative of the economically viable alternatives for dewatering Pit Lake.
The dewatering configuration under consideration is conveyance of pit water to the South Creek Reservoir prior to

INTRODUCTION
This memorandum is prepared in support of a NPDES application to document the water sampling events
and laboratory results that have occurred to date for the pit lake at the Albemarle Lithium Project
(Project)in Kings Mountain,North Carolina. The water quality results presented in this memorandum
were utilized in the NPDES application in Section 4 and represent the expected discharge quality.
SAMPLING EVENTS TO DATE
2018 Sample Collection
SRK Consulting(SRK) conducted a preliminary sampling event in November 2018. During that event
two pit lake samples were collected. The collected samples are described as:
• Sampled from middle of the pit lake by boat, 10 cm below surface; and
• Sampled from boat,near historic divide between two pit lake areas,recently overtopped as a
result of recent rains, forming one mixed pit lake.
A memorandum documenting the 2018 sampling event and results is included in Appendix A.
2022 Sample Collection
SWCA Environmental Consultants (SWCA)began the collection of baseline water quality data of the
Project pit lake in 2022; sample collection locations are displayed in Table 1 below.

Quarterly Monitoring
SWCA collected water quality samples in the pit lake for the second quarter and third quarter of 2022.
Water quality samples for PL-2,PL-5, and PL-8 were collected at depths of 10 feet, 50 feet, and 80 feet.
The deep pit lake sampling location was to the third quarter water quality sampling event; samples were
collected at 80 feet, 100 feet, 120 feet, 140 feet, and 160 feet. The water samples were processed by ACZ
Laboratories in Steamboat,Colorado. The third quarter water quality data is preliminary in nature. The
laboratory results are attached in Appendix A.
Field Parameters
SWCA collected field parameter readings for the pit lake in four separate sampling events. The field
parameters collected are temperature,pH, specific conductivity,and dissolved oxygen. Locations PL-2,
PL-5, and PL-8 were sampled in 5-foot intervals in-situ from total depth to surface. These three locations
were sampled in April 2022,May 2022, and September 2022. An additional pit lake sampling location,
PL-DEEP,was added in September 2022 to assess the water quality in the deepest portion of the pit lake.
PL-DEEP was sampled in 20-foot intervals using a flow-through cell. The field parameter results are
included in Appendix B.
Data Usage on Permit Application
The laboratory and field parameter results from the pit lake samples presented in Appendices A and B
were utilized to complete Section 4. Effluent Characteristics of the EPA Form 2E.

Subject: Kings Mountain Water Sampling Program
1 Introduction
SRK Consulting completed a preliminary sampling program to provide baseline water quality
information to support the PFS engineering study. Samantha Barnes from SRK Canada was on
site at the Albemarle facilities on November 21s'and 22nd, 2018.
The goal of the program was to collect water samples from water features across the historic
working areas, including pit lakes, natural lakes, streams, or ponded areas. A total of 8 surface
water samples were collected.
The following memorandum summarizes the data collected during the sampling program.
2 Sampling Program
2.1 Sample Locations
A total of 8 surface water samples were collected on site. Sample locations are presented as
green dots in Figure 1.
Three additional locations were visited, including GW Well #2 and Well#3, as well as the
Pegmatite 25 Pond. Samples were not collected at these locations due to issues with access or
equipment.

2.2 Sample Data
A YSI DSS water quality probe was used to measure in-situ water quality at each sample
location, including pH, electric conductivity(pS/cm), oxygen reduction potential (ORP, in mV),
and temperature (degrees Celsius). Sample coordinates were collected using a handheld Garmin
GPS and reflect metric UTM coordinates in Zone 17S.
Data collected at each location are presented in Table 1.
Sampling included collection of water in the following bottles for associated lab analysis:
• 1 x 500 mL bottle for wet chemistry
• 2 x 4L bottles and 1 x 1000 mL bottle for radiochemistry (total)
• 1 x 250 mL bottle for total metals
• 1 x 250 mL bottle for dissolved wet chemistry(filtering recommended)
• 1 x 250 mL bottle for COD, TOC, Phenols and total wet chemistry
Insufficient 4L jugs were provided to collect the radiochemistry samples for all locations. Samples
KM_SW_01 through KM_SW_06 included the two 4L bottles for radiochemistry, while
KM_SW_07 and KM_SW_08 do not include the 4L bottles, as denoted by the grey hatch in Table
1.
Filtering of samples for dissolved wet chemistry bottles was achieved using a syringe and 0.45
pm filter. Filters were depleted after sampling KM_SW_01 through KM_SW_04, as denoted by
the blue hatch cells in Table 1. All other sample locations did not receive filtering for the dissolved
wet chemistry bottles.

2.3 Additional Sampling Attempts
2.3.1 Groundwater Wells
Malfunction of the Geotech bladder pump resulted in inability to sample from GW Wells#2 and
#3. Depths to water were measured to be 31.4 ft and 14.1 ft, for GW#2 and GW#3 respectively.
2.3.2 Waterbodies
Access to the Pegmatite 25 Pond included two sets of old steel staircases, which had not been
maintained. Sampling of the pond was deemed unsafe due to the steep pit walls and old
staircases. No sample was collected.
The property boundary at the time of the site visit limited sampling on the south side of Highway
85 to the two sites. Nearby waterbodies noted from aerial imagery were not within the boundary
area and were therefore not sampled.
3 Summary
A total of eight surface water samples were collected over a two day period on site in November
2018.
Future investigations should also target groundwater wells to evaluate baseline water quality in
the groundwater.

Engineering Alternative Analysis in Support of NPDES Application
ABSTRACT/EXECUTIVE SUMMARY
To support the application of a North Carolina National Pollutant Discharge Elimination System
(NPDES)to discharge water that has accumulated in an historic mine pit on-site,an Engineering
Alternatives Analysis(EAA) for the Albemarle Kings Mountain Lithium Project(Project) has been
prepared. The proposed discharge under the NPDES application includes dewatering an existing mine pit,
conveyance of pit water to the South Creek Reservoir prior to discharging to Kings Creek. The proposed
outfall is the northeastern edge of South Creek Reservoir,which has an outfall consisting of two 36-inch
high density polyethylene (HDPE)pipes. The approximate location of the existing outfall is
35°12'42.70"N, 81°21'19.05"W. Kings Creek, a North Carolina Class C perennial stream with its
headwater near the existing mine pit,bisects the site before flowing south through a culvert under
Interstate 85 (1-85).
Proposed alternatives reviewed for this analysis include connection to a wastewater treatment plant, land
application,water reuse, as well as a combination of alternatives. Based on the analysis,pipeline
connection to TJ Ellison WTP was the only feasible alternative, although a combination of land
application and discharge to Kings Creek was also possible.A 20-year Present Value of Costs Analysis
indicates that the Direct Discharge Alternative is the most cost effective based on the short duration of
discharge (1 —2 years).

Engineering Alternative Analysis in Support of NPDES Application
1 INTRODUCTION
On behalf of Albemarle Corporation(Albemarle), SWCA Environmental Consultants(SWCA)has
prepared this Engineering Alternatives Analysis(EAA) for the Albemarle Kings Mountain Lithium
Project(Project)located in Cleveland County,North Carolina. This EAA is in support of a permit
application under the North Carolina National Pollutant Discharge Elimination System(NPDES)to
discharge water that has accumulated in an inactive mine pit on-site.
Mining activities associated with the Kings Mountain spodumene deposit began as early as the late 19'
century with full scale production beginning with the issuance of a mining permit in 1950. Mining
activities ceased later in the 20t'century; as a result of mine closure,pit dewatering activities were ceased
and the pit was allowed to fill unencumbered, save a discreet period where a portion of the water was
provided to an adjacent aggregate quarry operated by Martin Marietta Materials, . Water entering the
mine pit is a combination of surface flow,groundwater inflow, and direct precipitation,to fill a volume
currently estimated at approximately Ibillion gallons.As the global market for lithium increases,
Albemarle is evaluating reopening the Kings Mountain Mine to resume mining the spodumene deposit.
Dewatering the historic mine pit is necessary to resume mining operations.
Dewatering is anticipated to take between 8 and 24 months, and to be a one-time discharge event.As such
an Individual Permit(Application Form 2E Manufacturing, Commercial, Mining, and Silvicultural
Facilities Which Discharge Only Nonprocess Wastewater)has been prepared, and includes an
Engineering Analysis(SWCA,2022) and this Engineering Alternatives Analysis(EAA). The North
Carolina Division of Water Resources Environmental Engineering Analysis Guidance Document for new
or expanding wastewater treatment plant was used as the basis for preparing this document.

2.2 Project Description and Proposed Discharge Location
The Project Site(Site)is located approximately 1 mile south of downtown Kings Mountain in Cleveland
County,North Carolina and consists primarily of historically mined land,forested land,maintained utility
rights of-way, and industrial mining processing facilities(Figure 1).

Engineering Alternative Analysis in Support of NPDES Application
Albemarle proposes to dewater an existing mine pit and recommence active mining,with the water from
the pit lake to be discharged to Kings Creek. The current dewatering configuration under consideration is
conveyance of pit water to the South Creek Reservoir located onsite prior to discharging to Kings Creek.
The proposed outfall is the northeastern edge of South Creek Reservoir,which consists of two 36-inch
HDPE pipes. The approximate location of the outfall is 35°12'42.70"N, 81°21'19.05"W. The proposed
configuration is shown in Figure 2.
Kings Creek,a North Carolina Class C perennial stream with its headwaters occurring near the existing
mine pit,bisects the site before flowing south through a culvert under Interstate 85 (1-85). The Project
Reach studied for the purpose of this report extends from the headwaters of Kings Creek to where Kings
Creek leaves the Site approximately 2,000 linear feet downstream of the 1-85 culvert. The total length of
the studied reach of Kings Creek(Project Reach)is approximately 6,080 linear feet.
Based on the measured and observed condition of the existing stream bed and banks,minor increases in
flow due to the mine pit dewatering is not expected to adversely impact the banks of Kings Creek, and no
discernible change to the stream competency or stability is expected. Additionally,the increase in flow is
not expected to increase flood elevations beyond the subject property line or adversely impact adjacent
properties.
Water quality of the discharge water contained within the pit varies with depth,however,does not exceed
Class C standards. The proposed action will use South Creek Reservoir as an equalization pond to allow
for lower temperature and oxygen levels in the lower portion of the pit to adjust to ambient levels prior to
discharge to Kings Creek.
The water quality of Kings Creek has the following noteworthy parameters:
• Ammonia and sulfide concentrations were below the detection limits
• Sulfate concentrations range from 70 to 145 mg/L.
• pH is circumneutral range from 7.2 to 7.5.
• Temperature ranged from 16°C, above the discharge point,to 25°C, at and below the discharge
point.
An aquatic assessment of all onsite waterbodies indicated that all species of fish,crustaceans,and
bivalves encountered during surveying are listed as Least Concern by the International Union for
Conservation of Nature.No Federal or State aquatic species of concern occur in the Project area.
According to the United States Geological Survey(USGS), the streamflow characteristics for Kings
Creek at the proposed discharge location are as follows:
• Annual 7Q10 low-flow yields are 0.13 to 0.38 csfm(average approximately 0.19 csfm,median
about 0.17 csfin);
• Annual 30Q2 low-flow yields are 0.35 to 0.68 csfin(average about 0.47 csfin,median about 0.44
csfin);
• Winter 7Q10 low flow yields are 0.23 to 0.58 csfin(average about 0.35 csfm,median about 0.33
csfin);
• Annual 7Q2 low flow yields are 0.26 to 0.6 csfm(average about 0.37 csfin and median about
0.34 csfm); and

• Average annual discharge yields are 1.2 to 1.4 csfm(both average and median are about 1.3
csfin).

3 EAA STEP 2: NON-MUNICIPAL FLOW PROJECTIONS
Development of population projections required for Step 2 apply to municipal treatment facilities as a
means to quantify flow and load increases due to population change. Albemarle does not own or operate
any municipal treatment facilities, and projected water flow is independent of population changes.
Additionally,this permit is being applied for as a single use permit to dewater an inactive mine pit that
has accumulated surface water runoff, groundwater inflow, and direct precipitation since operations
ceased.Albemarle requires the ability to discharge 5.040 MGD (3,500 gpm)to dewater the inactive mine
pit. Dewatering is expected to last approximately 8 to 24 months.
4 EAA STEP 3: EVALUATE TECHNOLOGICALLY
FEASIBLE ALTERNATIVES
North Carolina Department of Environment requires new or expanding wastewater discharge must
consider the feasibility of other wastewater disposal methods in addition to direct discharge. The EEAA
Guidance Document provided by the North Carolina Division of Water Resources outlines the
preparation protocol and the alternatives that must be considered in the study.
4

Engineering Alternative Analysis in Support of NPDES Application
Six alternatives are considered for technical feasibility and environmental soundness and has been used as
a basis for reviewing potential alternatives to direct description. A description of each alternative and
discussion of the technical feasibility is described below.
Alternatives considered are:
A. Connection to an Existing Wastewater Treatment System
B. Land Application
C. Wastewater Reuse
D. Direct Discharge to Surface Waters
E. Combination of Alternatives
4.1 Alternative A: Connection to an Existing Wastewater
Treatment System
Alternative A necessitates applicants consider the feasibility of connecting to an existing wastewater
treatment system that holds a valid NPDES or Non-Discharge Permit. When considering connection with
an existing wastewater treatment system, applicants must consider the following parameters:
• Existing sewer lines within a five-mile radius or expand the radius beyond five miles if that is
cost effective for the project.
• Gravity drain systems must be considered if sewer lines do not exist.
• Flow acceptance of existing wastewater treatment systems.
• Evaluation of piping/pumps/resources necessary to connect with existing wastewater treatment
plant.
• Present Value Cost Analysis for connecting to existing wastewater treatment system.
4.1.1 Alternative Al. Pump to TJ Ellison Water Treatment Plant
The TJ Ellison Water Treatment Plant(WTP)is a municipal water treatment plant located approximately
6 miles from the Project Site in Kings Mountain,North Carolina. The TJ Ellison WTP is a current
NPDES permit holder and has a permitted capacity of 12.0 MGD.
Alternative Al is connection by force main to an existing water treatment system. Based on a 2018
NPDES permit renewal application submittal,the TJ Ellison Water Treatment Plant has a water treatment
capacity of 12 MGD.At a discharge of 5.040 MGD,Albemarle site water would represent approximately
42%of TJ Ellison WTP influent..
Alternative Al is only feasible if water is conveyed via connection by force main to an existing water
treatment system.An existing wastewater pipeline enters the Kings Mountain property at the northeast
corner of the property along Quarry Road. SWCA will request as-built drawings from the Kings
Mountain municipality to determine whether existing pipeline is large enough to accommodate 3,500
gpm; however, for the purpose of this exercise SWCA assumes that the pipeline has sufficient capacity.
5

Engineering Alternative Analysis in Support of NPDES Application
4.1.2 Alternative A2: Pump to Pilot Creek Wastewater Treatment
Plant
The Pilot Creek Wastewater Treatment Plant(WWTP) is a municipal wastewater treatment plant located
approximately 7 miles from the Project site in Kings Mountain,North Carolina. The Pilot Creek WWTP
is a current NPDES permit holder and has a permitted capacity of 6.0 MGD.
Alternative A2 is connection by force main to an existing wastewater treatment system. Based on a 2018
NPDES permit renewal application,the Pilot Creek WWTP has a design flow rate of 6.0 MGD. At a
discharge rate of 5.040 MGD, dewatering of the existing mine pit would represent approximately 84%of
Pilot Creek WWTP. Operational data included in the 2018 permit renewal application indicates that the
Pilot Creek WWTP has an annual average flow rate of 1.857 MGD and maximum daily flow rate of 4.297
MGD.
Alternative A2 is deemed not technically feasible as a single discharge alternative because Albemarle's
daily discharge of 5.040 MGD exceeds Pilot Creek's remaining hydraulic capacity of 4.143 MGD under
typical operating conditions.
4.2 Alternative B: Land Application
Alternative B is the land application disposal and components include individual/community onsite
subsurface systems, drip irrigation,and spray irrigation. As part of this alternative,the following was
considered:
• An estimate of base case hydraulic loading rate.
• An assessment of the availability of land.
• A description of the non-discharge application system.
• A present value cost analysis for the reclaimed water system.
For this study,Alternative B is to land apply water by spray irrigation via a non-discharge permit.
To estimate the acreage required for land application, soil drainage rates were calculated using an average
soil drainage rate for land owned by Albemarle in the immediate vicinity of the pit lake(NRCS Web Soil
Survey). The soil classification is UdC—udorthents, loamy, 0 to 15% slopes—with a K,at that ranges from
0.00 in/hr to 1.98 in/hr. Land application for subsurface seepage is not a feasible discharge method
because the most conservative seepage rate is 0.00 in/hr. Precipitation and evapotranspiration data was
retrieved from the NC CRONOS database for Station ID KEHO in Shelby,North Carolina(annual rate of
34.72). Evapotranspiration data was retrieved from Maysville,North Carolina(annual rate of 39.75
inches).
To calculate the land required for atmospheric evaporation disposal,the annual Class A Pan Evaporation
rate of 39.75 inches(3.3125 feet)per year with an evaporation adjustment rate of 75%was used Using
these values,the land required for atmospheric evaporation disposal can be calculated as follows:
1,839,600,000 gallons
Area = Volume _ year = 1,704.31 acres
Evaporation Rate 39.75 inches
year
6

Engineering Alternative Analysis in Support of NPDES Application
Of the 1,403 acres that Albemarle currently owns at the Project Site, only 534 acres north of the I-85 are
suitable for land application. As such,there is insufficient land area for adequate land disposal.
Finally,land application is primarily suitable for rural areas with high infiltration rates.While Albemarle
does own over 1,000 acres,the land is generally unsuitable for land application due to reclaimed, low
infiltration waste rock piles and steep slopes.
4.3 Alternative C: Wastewater Reuse
Alternative C requires the evaluation of reusing all or a portion of the water generated. Examples of reuse
that are provided in the EAA Guidance Document include: irrigation,toilet flushing,backwashing, and
commercial and industrial uses. The guidance document specifically notes that some of the reuse
applications may overlap with uses identified in Alternative B.
On-site reuse as a single point discharge alternative was not deemed feasible as the quantity of water
pumped from the pit lake greatly exceeds onsite need. With a planned dewatering rate of 3,500 gallons
per minute,the pit lake will supply 5,040,000 gallons of water per day. The City of Kings Mountain
delivered 74,977 cubic meters(19,806,828 gallons) of water to Albemarle in 2021,which averages to a
daily demand of 54,265.3 gallons per day. As such,Albemarle's onsite water needs could only consume
1.08%percent of the daily dewatered volume.
Reuse at facilities in the community was evaluated. A 5-mile radius was selected as the practical distance
for a cost-effective pipeline. The recreational lakes that are operated by the city are separated from the site
by a major US interstate(1-85) and these lakes are fed by streams which keeps them at capacity. Moss
Reservoir,the City of Kings Mountain water supply,is approximately 7 miles from the site with the town
of Kings Mountain and a divided major highway lying in between.No additional facilities within the 5-
mile radius would require enough water that is not already supplied by others.
4.4 Alternative D: Direct Discharge to Kings Creek via
South Reservoir
The proposed discharge to Kings Creek is shown in Figure 2 and described in Section 2.2. Detailed
analysis of potential impacts to Kings Creek are detailed in a supporting Engineering Analysis(SWCA,
2022).
4.5 Alternative E: Combination of Alternatives
Alternative E is the evaluation of a combination of wastewater alternatives that would minimize or
eliminate a direct discharge alternative. An example of a suggested combination is to consider whether
the facility can operate a land application system during the dry season when stream flows are at their
lowest and provide less dilution and operate an NPDES discharge system during the wet season when
soils may not be as amenable to land application and the receiving stream provides its greatest dilution.
For this study,Alternative E is land application in addition to direct discharge to Kings Creek. The land
application system will be sized to irrigate 536 acres which the maximum number of acres that Albemarle
owns that is suitable land application(as identified in Alternative B). With an annual evaporation rate of
39.75 inches,the amount of what that can be consumed annually is 578,549,211 gallons per year, or 1,100
gpm. The remaining flow that cannot be consumed by spray irrigation(2,400 gpm)will be discharged to
Kings Creek via South Reservoir as described in Alternative D.

Engineering Alternative Analysis in Support of NPDES Application
5 EAA STEP 4: EVALUATION OF THE ECONOMIC
FEASIBILITY OF THE ALTERNATIVES
To provide valid cost comparisons among all technologically feasible wastewater alternatives identified in
Step 3,a 20-year Present Value of Costs Analysis(PVCA)was performed. A preliminary design level
effort was considered appropriate for comparing feasible options and their associated costs. For the
PVCA cost comparison, all future expenditures were converted to a present value cost at the beginning of
the 20-year planning period. A discount rate is used in the analysis and represents the time value of
money(the ability of money to earn interest). Present value is also referred to as "present discounted
value" or"present worth". One year of sustaining costs are included in the PVCA calculation as pit
dewatering is expected to last eight months. The PVCA includes costs associated with construction,
startup and annual operation and maintenance of a facility.
The standard formula for computing the present value is:
n
Ct
PV = Co +
(1 +r)
t=1t
Where:
PV=Present value of costs
Co=Costs incurred in the present year
Ct=Costs incurred in time t
n=Ending year of the life of the facility
r=EPA discount rate(2.25%based fiscal year 2022)
A PVCA was prepared for Alternatives Al, D, and E.Alternatives A2,B,and C were deemed not
technically feasible. The PVCA assumes that capital costs are incurred in year 1 and operational costs are
incurred in year 2 at the current EPA discount rate of 2.25%. Costs past year two were not relevant to the
PVCA calculation because the existing mine pit will be completely dewatered by the end of year 2.
5.1 Alternative Al PVCA: Pipeline Connection TJ Ellison
WTP
Capital costs for Alternative Al include a discharge pump station and a pipeline to connect the pit to the
existing municipal pipeline at the edge of the property. The PVCA assumes that upgrades to the TJ
Ellison WTP are not required for the facility to accept the additional flow as the facility is currently
constructed and permitted for 12 MGD.
Recurring costs incurred in year 2 include:
• TJ Ellison WTP Sewer Use Fees
• Operation and maintenance
• Laboratory analysis
8

Engineering Alternative Analysis in Support of NPDES Application
• Labor
• Energy
5.2 Alternative D: Direct Discharge to Kings Creek via
South Reservoir
Alternative D is direct discharge of water to Kings Creek via the South Creek Reservoir.
Capital costs for Alternative D include a discharge pump station and a new pipeline connecting the
existing mine pit to South Reservoir.
Recurring costs incurred in year 2 include:
• Operation and maintenance
• Laboratory analysis
• Labor
• Energy
5.3 Alternative E: Combination of Alternatives - Direct
Discharge to Kings Creek and On-site Evaporation
Alternative E includes the combination use of on-site evaporation as well as direct discharge to Kings
Creek.
Capital costs for Alternative E include a discharge pump station, spray evaporators,pumps and
instrumentation to feed the evaporators, and a new pipeline to connect the existing mine pit to South
Reservoir.
Recurring costs incurred in year 2 include:
• Operation and maintenance
• Laboratory analysis
• Additional labor
• Energy
5.4 Comparison of Present Value of Costs Analysis
A detailed comparison of the PVCA is displayed below in Table 1.
Table 1. Summary of Present Value Cost Analysis
Alternative Description Present Value(Million$)
Al Pipeline Connection to TJ Ellison WTP $15.1
9

Engineering Alternative Analysis in Support of NPDES Application
Alternative Description Present Value(Million$)
A2 Pipeline Connection to Pilot Creek WWTP Not Feasible
B Land Application Not Feasible
C Reuse Not Feasible
D Direct Discharge to Kings Creek via South Reservoir $2.2
E Direct Discharge to Kings Creek and On-site Evaporation $3.3
Alternatives A2,B, and C are not feasible. Alternative A2 is deemed not technically feasible as a single
discharge alternative because Albemarle's daily discharge of 5.040 MGD exceeds Pilot Creek's
remaining hydraulic capacity of 4.143 MGD under typical operating conditions. Alternative B is not
feasible because Albemarle does not own sufficient land to consume 3,500 gpm land application.
Alternative C is not feasible because Albemarle's daily external water consumption is 1.08%of the
proposed pit watering flow. While Alternative Al is feasible, it is nearly 500%more expensive than the
next considered alternative rendering this alternative not economically feasible. The high PVCA for this
alternative is driven by high disposal fees associated with utilizing a municipal treatment system.While
alternative E is feasible it is 50%more expensive than Alternative D. Additionally, investment in the
extensive evaporation system required to execute Alternative E is not an environmentally friendly
alternative because discharge of the historic pit lake is projected to be completed within two years.
Based on the PVCA and the analysis performed herein, direct discharge to Kings Creek is deemed the
most environmentally sound alternative of the economically viable alternatives for the dewatering of the
pit lake.

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
1 INTRODUCTION
On behalf of Albemarle Corporation(Albemarle), SWCA Environmental Consultants(SWCA)has
prepared this Kings Creek Stability and Water Quality Assessment for the Albemarle Kings Mountain
Lithium Mining Project(Project),located in Cleveland County,North Carolina(Appendix A).
1 .1 Background
Albemarle proposes to dewater an existing pit lake and recommence active mining,with the water from
the pit lake to be discharged to Kings Creek. The current dewatering configuration under consideration
is conveyance of pit water to the South Creek Reservoir prior to discharging to Kings Creek. The
proposed outfall is the northeastern edge of South Creek Reservoir,which has two existing 36-inch
gravity-fed drainpipes. The approximate location of the existing gravity fed drainpipes is 35'
12'42.70"N, 81°21'19.05"W.
The 1,403-acre Project Site(Site) is located approximately 1 mile south of downtown Kings Mountain,
North Carolina, and consists primarily of historically mined land, forested land,maintained utility
rights-of-way, and industrial mining processing facilities.
Kings Creek,a North Carolina Class C perennial stream with its headwater near the existing mine pit,
bisects the site before flowing south through a culvert under Interstate 85 (1-85). The Project Reach
studied for the purpose of this report extends from the headwaters of Kings Creek to where Kings Creek
leaves the Site approximately 2,000 linear feet downstream of the 1-85 culvert. The total length of the
studied reach of Kings Creek(Project Reach) is approximately 6,080 linear feet.
1 .2 Objectives
This report describes the methods and results of assessments performed to evaluate the impact of
discharging water from the existing mine pit water to Kings Creek,as well as SWCA's recommendations
for the dewatering process. The main objectives of these assessments were to evaluate current channel
stability and water quality conditions and to assess impacts, if any,to Kings Creek in order to ensure
National Pollutant Discharge Elimination System(NPDES) compliance is met. Potential impacts are
based on four major factors:
• changes in flow rate
• impacts to the physical structure of Kings Creek(potential for increased total suspended solids
(TSS)or turbidity)
• impacts to water chemistry
• impacts to the aquatic system(i.e., sensitive species)
2 STABILITY ASSESSMENT
2.1 Hydrology
In order to estimate expected flows through the Project Reach and evaluate channel stability, a desktop
hydrologic analysis of the watershed was completed. The 1-year, 100-year, and 24-hour storm events
were studied to represent a near-bankfull storm event and a major flood event.
1

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
The watershed was divided into four sub-basins delineated to points of analysis along the Project Reach
using QL1 LiDAR data from North Carolina's Spatial Data records. Points of analysis were selected
based on where there were significant changes in drainage area, such as inflow points or in-stream
culverts. The most upstream sub-basin, Sub-basin 1, does not include the drainage area that flows into the
existing pit lake or the Martin Marietta quarry since the outflows from those features are controlled
through pumping processes.
A composite curve number was assigned to each sub-basin based on land cover derived from the latest
available aerial imagery and soil types present according to the Natural Resources Conservation Service
(MRCS)Web Soil Survey. The subject watershed was classified as industrial,residential,or wooded land
cover with silty loam soils of Hydrologic Soil Groups(HSGs) `B' and `C'. Precipitation data was
obtained from NOAA Atlas 14 for Cleveland County,North Carolina.
Peak discharges were computed in the Hydraflow Hydrographs Extension for AutoCAD Civil 3D using
the NRCS TR-55 method(USDA,NRCS 1986). Baseflow conditions were calculated using field readings
from an existing onsite v-notch weir in Kings Creek located just upstream of I-85. A summary of
discharges are presented in Table 1 below. Hydrologic calculations and watershed drainage maps are
provided in Appendix B.

3 0.5 258.9 2,057.3
4 0.5 579.1 3,635.2
Note:Discharge values are derived from watershed hydrology and do not include proposed dewatering flow or existing inflow from the adjacent mining
operation.
cfs=cubic feet per second
2.2 Hydraulic Model
A hydraulic model provides quantitative results of channel hydraulics, such as channel velocities, shear
stresses, and flood elevations, critical to the evaluation of channel stability. Kings Creek was modeled
using US Army Corp of Engineers(USACE)HEC-RAS Version 6.1.0 software(USACE 2021).
Hydraulic parameters for stability assessment were computed using the peak discharge estimates and
geometry data of the existing channel.
2.2.1 Methodology
A 1-Dimensional steady-state model was created to compare existing and proposed channel hydraulics
and the effects of the proposed dewatering flow through the Project Reach. Channel geometry of Kings
Creek was derived from cross section survey data provided by Geospatial Professionals, Inc. (GPI) and
QL1 LiDAR data.A Manning's n roughness coefficient based on aerial imagery and field reconnaissance
was assumed as 0.035 within the channel,which is representative of a clean,winding stream channel, and
0.10 for the well-vegetated left and right over banks (Arcement et. al. 1989). Existing stream structures
including bridges, culverts, and weirs were integrated into the model based on survey data provided by
GPI.
2

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
Steady-state models require both upstream and downstream boundary condition data. Since the upstream
water surface elevation was not available for each flood event, a critical depth was assumed for the
upstream boundary condition. The downstream boundary condition was calculated based on normal
depth.Normal depth is derived from the average energy grade line slope which is assumed constant and
equivalent to the downstream bed slope of Kings Creek, calculated at 0.012.
Four scenarios were run and analyzed for Kings Creek:
• existing conditions,
• proposed additional discharge conditions,
• existing conditions with Martin-Marietta quarry pumping, and
• proposed additional discharge conditions with Martin-Marietta quarry pumping.
The existing and proposed conditions used identical geometry and boundary condition data with the only
variance being the flow data. Existing flows were based on watershed hydrology and the estimated peak
flows for the 1-year, 100-year,and baseflow events. Additional inflow to Kings Creek from the adjacent
Martin-Marietta quarry was added at cross section 65+73.11 and estimated as a constant 2,250 gpm
(5.01 cfs),provided by Martin Marietta. Proposed conditions assumed an additional 3,500 gpm(7.80 cfs)
of constant flow enter Kings Creek at cross section 38+80.56,representative of the proposed dewatering
flow from the inactive Albemarle pit lake. Combined,this represents a constant flow of 5,750 gpm(12.81
cfs)into Kings Creek below the discharge point during the dewatering event.
Additional data pertaining to hydraulic modelling methodology and results are presented in Appendix B.
2.2.2 Results
The results of the hydraulic model were evaluated in terms of channel stability and flooding potential and
are summarized in the following sections.
2.2.2.1 STABILITY
Channel stability was assessed based on permissible velocities and shear stresses on the channel banks
during the baseflow and bankfull events, since negligible differences were found in the 100-year storm
event.Assuming long native grass vegetation cover on the banks of Kings Creek,the permissible velocity
was 6 ft/s and the permissible shear stress 1.71b/ft2 in order to maintain channel stability(Fischenich,
2001).A summary of the hydraulic model results can be found in Table 2.
Table 2. Hydraulic Parameter Average Summary
Storm Event Existing Velocity(ft/s) Proposed Velocity Existing Shear Stress Proposed Shear
(ft/s) (Ib/ftz) Stress(lb/ft2)
Baseflow 1.94 2.09 0.26 0.29
1-Year 5.55 5.56 1.22 1.22
100-Year 8.33 8.33 2.03 2.03
Note:All values are an average of the hydraulic model results for the stream channel across the entire Project Reach.
The most significant changes are found to occur in the baseflow condition. Only minor increases in these
values are seen between existing and proposed conditions, and Kings Creek is well within the velocity

and shear thresholds in the proposed condition. This indicates that the increase in flow due to the pit lake
dewatering is not expected to adversely impact the stability of Kings Creek.
2.2.2.2 FLOODING EXTENTS
The downstream end of the Project Reach is confined by an accumulation of branches and sediment,
alternatively referred to as Weir#7.Adjacent property owners have voiced concerns about flooding
caused by Weir#7 in the existing condition. Potential flooding extents were assessed to ensure the
additional flows do not result in encroachment onto adjacent properties.
Negligible increases in flooding depth associated with the added discharge are anticipated in the area
surrounding Weir#7 based on the hydraulic model results summarized in Table 3.Using a surface
derived from QL1 LiDAR data, a 2-Dimensional steady-state HEC-RAS model was created to estimate
flooding extents for the 100-year storm event. Flooding is not expected to extend beyond the subject
property line or impact adjacent properties as shown in Appendix D.
Table 3. Flooding Depth Summary
Storm Event Pond Depth—Existing Conditions(ft) Pond Depth—Proposed Conditions(ft)
Baseflow 0.70 0.80
1-Year 3.04 3.05
100-Year 7.67 7.68
Note:All values are an average of the hydraulic model results for the stream channel across the entire Project Reach.
SWCA performed desktop and field assessments to evaluate the Project's watershed hydrology and
existing fluvial geomorphologic conditions of the Project Reach. These assessments provide good
indicators for determining the overall channel stability of Kings Creek. The methodologies applied are
described in the following sections.
2.3 Sediment Classification
Stream bed and bank material play a significant role in channel hydraulics. Classification of the sediment
material and its composition help to estimate erosion rates, sediment supply,and overall channel stability.
2.3.1 Field Methodology
The Wolman Pebble Count is a commonly used methodology to classify stream bed material and develop
a median particle size(1350)for a given reach. The median particle size is an essential parameter in
sediment transport calculations used to assess channel stability(Wolman 1954).
Wolman Pebble Count procedure involves recording size measurements of a minimum of 100 random
particle samples collected as an observer traverses the stream in a zig-zag pattern.Four SWCA employees
completed Wolman Pebble Counts at 15 locations along Kings Creek in June 2022. Since the purpose of
this assessment is to determine stream stability,particle samples were collected at riffle features only.
Riffles control stream slope and experience the highest velocities and shear stresses making them most
prone to instability. One hundred particle samples were measured with field rulers at each riffle location.
Size measurements were recorded based on the sample's b-axis, or the limiting size in which the particle
would pass through a sieve or gravelometer. Larger boulders or embedded particles were measured along
the shortest visible axis.
4

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
With the collected data, a particle curve was developed for each of the 15 sample riffle locations by
plotting the size distribution against frequency. The median particle size,Dso,was determined using the
curve and noting where 50%of the samples are equal to or smaller than the particle size. The same
methodology was used to calculate the Dsa and D95 for each riffle.
2.3.2 Results
The Dso at the 15 sampled riffle locations ranged from fine gravel(6-8 mm)to very coarse gravel(48-
64 mm).An average Dso was calculated across the entire Project Reach and determined to be
approximately 15 mm,which classifies as a medium gravel stream. Figure 1 displays existing
representative conditions in the Kings Creek streambed. This determination corresponds with
observations made in the field that a high percentage of the stream material was gravel. The Dso and D95
calculated for Kings Creek were 56 mm and 130 mm,respectively, indicating the presence of larger
cobble and boulders as well. Bedrock grade control was also noted throughout the Project Reach.All data
collection results are presented in Appendix C.

Sediment transport is the initiation of particle movement downstream and a key indicator in assessing
overall channel stability and potential for increases in Total Suspended Solids(TSS)or turbidity. Stream
competency is a measure of the maximum particle size a stream can transport. Therefore,the Dso,Dso,
and D95 for a reach can help provide an estimate of how much sediment is entrained, or being transported,
at different flow rates or storm events. The Shields relation is a common method to estimate stream
competency, or the ability to move the largest particle made available to the channel,based on critical
shear stress calculated in a stream channel (USDA,NRCS 2007).
5

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
As determined by the HEC-RAS model,the average bankfull shear stress experienced by Kings Creek is
estimated to be 1.21bs/ft2. Competency calculations indicate the expected movable particle size, as a
result,would fall between 94 and 170 mm,which falls between the D84 and D95 for the observed Project
Reach. This is indicative of a degrading or incising system. During field assessments,there were no visual
indicators noted that corroborated this conclusion,rather,Kings Creek appeared to be in a dynamic
equilibrium. SWCA assumes that this is likely a result of the pebble counts under-representing the
presence of bed rock grade control observed in the field. The presence of bed rock in the channel bed
would prevent any incision from occurring. The proposed additional discharge is expected to increase
shear stress by only 1%(0.01 lbs/ft2)when comparing existing to proposed shear stress within the HEC-
RAS model. This small increase in shear stress, from 1.21bs/ft2 to 1.21 lbs/ft2, does not change the
expected movable particle size,and therefore,no discernible change to the stream competency or stability
is expected.
2.4 Stream Bank Analysis
In addition to classification of streambed material, an analysis of stream bank condition is important in
estimating erosion potential and overall channel stability. Much of the suspended sediment found in
streams can be attributed to eroding stream banks. While some natural erosion is expected in a stable
stream,changes in watershed hydrology or sediment load due to anthropogenic influences increases the
potential for a deviation from naturally occurring erosion. Since flow in Kings Creek is expected to
increase as a result of the proposed mine pit dewatering, a stream bank analysis was performed to
estimate the allowable dewatering flow that would ensure no adverse impacts to the existing stream
banks.
2.4.1 Field Methodology
The Bank Erosion Hazard Index(BEHI)is a tool that can be used in the field to assess existing stream
bank conditions and erosion potential(Rosgen 2001).Values are assigned to five bank condition
parameters:
• bank to bankfull height ratio,
• root depth,
• root density,
• surface protection, and
• bank angle.
The parameters are scored and summed to determine the BEHI rating for a given stream section. BEHI
ratings are categorized from"very low"to"extreme",which aids in the understanding of the areas with
the highest erosion potential.A field assessment was completed by SWCA in June 2022. The Project
Reach was assessed in stream bank sections of varying lengths based on observed changing bank
conditions. Left and right banks were evaluated separately.
In addition to BEHI, a Near Bank Stress(NBS)Analysis was performed in the field as an additional
approach to evaluate stream bank condition(Rosgen 2001). There are seven NBS methods for evaluating
stream banks—SWCA utilized Method 1 which involves observing the location of flow relative to the
bank to determine erosion potential.NBS ratings are scored from"very low"to"extreme"for each
section of bank.
6

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
2.4.2 Results
SWCA walked approximately 5,100 feet of the Project Reach,between the headwater wetlands and the I-
85 culvert, and observed stream banks with good vegetation coverage and a moderately shallow bank
angle. Channel flows were primarily concentrated in the center of the channel with very little signs of
undercutting or erosion near the stream banks. As a result,a majority of the stream banks scored as "very
low"or"low"in BEHI and NBS ratings,indicative of stable stream banks with low erosion potential.
Table 4 summarizes the BEHI and NBS classifications given to the observed Project Reach. Additional
field data is presented in Appendix C.
Table 4. Stream Bank Analysis Summary
BEHI Classification NBS Classification Bank Length(ft) Reach Portion
Very Low Very Low 735 14%
Very Low Low 632 12%
Low Low 3,461 68%
Moderate Moderate 300 6%
Based on the measured and observed condition of the existing stream banks,minor increases in flow due
to the mine pit dewatering is not expected to adversely impact the banks of Kings Creek. The section of
stream with the highest erosion potential(moderate BEHI and NBS ratings)is located upstream of the
proposed discharge point and is not expected to be impacted by additional discharge associated with pit
dewatering. Figure 2 displays the existing representative conditions in a very low/low BEHI/NBS stream
bank and Figure 3 displays the existing representative conditions in a moderate BEHI/NHS stream bank.

3.1 Existing Water Quality Conditions
3.1.1 Pit Lake Water Quality
Analytical results are presented in Appendix E, compared to North Carolina Class C Water Quality
Standards and summarized below
Shallow pit lake waters
• The shallow pit lake waters are circumneutral to slightly alkaline,with a pH range of 7.7 to 9.1.
• The temperature has an average temperature of 22°C.
• The water is oxygenated,with PL-2 and PL-5 exceeding an oxygen saturation of 8 mg/L.
Dissolved oxygen at PL-8 is under-saturated at 5.4 mg/L,which could be attributed to less mixing
with surface waters at PL-8 compared to PL-2 and PL-5.
10

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
• There was no exceedance of Class C water quality standards(Appendix E).
Medium depth pit lake waters(-50 feet)
• The medium depth pit lake waters are circumneutral to alkaline,with a pH range of
approximately 7.5-9.2.
• The temperature is cooler and more homogonous than shallow pit lake waters with a range of
8.4°C to 8.5°C.
• The medium depth pit lake waters are largely depleted of oxygen to anoxic,with a dissolved
oxygen concentration ranging from 0.2 mg/L to 0.8 mg/L. The lack of dissolved iron at medium
depths indicates the dissolved oxygen concentration may trend towards low oxic.
• There was no exceedance of Class C water quality standards for metals concentrations.
Deep pit lake waters(>-80 feet)
• The deep pit lake waters are circumneutral,with a pH of approximately 7.6.
• The temperature is homogonous and consistent with the medium depth pit lake waters with
measurement of 8.7°C at the three sampling locations.
• Like the medium depth pit lake,the deep pit lake waters are anoxic with a dissolved oxygen
concentration ranging from 0.45 mg/L to 1.97 mg/L. The presence of moderate concentrations of
sulfide(18.4 mg/L to 29.2 mg/L) is indicative of fully anoxic conditions.
• The presence of ammonia(3.61 mg/L to 3.93 mg/L)in deep pit lake waters support reducing
conditions in the deeper lake.
• There was no exceedance of Class C water quality standards for metal concentrations.
3.1.2 South Creek Reservoir Water Quality
South Creek Reservoir will be used as an equalization pond prior to discharge to Kings Creek. Current
water quality within South Reservoir does not exceed any water quality standards, other than slightly
lower dissolved oxygen. The current water within the reservoir will initially be discharged into Kings
Creek
3.1.3 Kings Creek Water Quality
One water quality sample was collected above the discharge point and two water samples were collected
from Kings Creek—one at Weir#3 (KMSW-3) immediately below the discharge point and one further
downstream at Weir#7 (KMSW-3a)near the property boundary. The water samples were generally
similar from upstream of the discharge point,the discharge point and the downstream of the discharge
point,with the exception of dissolved oxygen. Upstream and downstream samples were anoxic,while the
discharge point had reasonable oxygen levels.
Water quality of Kings Creek compared with several water quality parameters of the pit lake include:
• Ammonia and sulfide concentrations were below the detection limits.
• Sulfate concentrations range from 70 to 145 mg/L.
• pH is circumneutral range from 7.2 to 7.5.
11

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
• Temperature ranged from 16°C above the discharge point to 25°C at and below the discharge
point.
• North Carolina Class C Water Quality Standards were not exceeded for any metal analytes. This
includes hardness-dependent water quality standards for both the hardness of the pit lake and the
hardness at 100 mg/L
3.1.4 Aquatic Assessment
SWCA conducted an aquatic habitat assessment to determine the aquatic faunal assemblage of the ponds
and streams within the Project area(Appendix G). SWCA conducted a desktop analysis of publicly
available information to characterize the lake,pond,wetland, and stream habitat within the Project area
that would be surveyed. SWCA previously conducted a wetland and waterbody delineation in February
and March of 2022 (SWCA 2022a). Observations from these surveys were also utilized when determining
suitable habitat and sampling areas for the aquatic surveys.
These sources were also used to determine a short list of aquatic species of concern with the potential to
occur in the Project area(Table 5). Seven state-listed aquatic species were identified as having the
potential to occur in the Project area,although none were listed as state threatened or endangered.No
federally listed aquatic species were identified. More detailed species descriptions are provided under
separate cover in SWCA's(2022b)Federally and State-Listed Species Report for the Kings Mountain
Lithium Mine, Cleveland County,North Carolina.

SWCA utilized three main methods to assess the aquatic habitats observed within the Albemarle
properties: trapping fish within pond habitats, electrofishing in streams, and visual and tactile surveys of
streams for aquatic macroinvertebrates(primarily freshwater mollusks and crayfish). Aquatic surveys
were conducted between August 22nd through August 26th, 2022.All collected animals were identified
to species and released at their capture location. Additional data including animal lengths and sexual
characteristics was collected.

Kings Creek Stability and Water Quality Assessment—Kings Mountain Lithium Mining Project
All species of fish, crustaceans, and bivalves encountered during surveying are listed as Least Concern by
the International Union for Conservation of Nature. The results of SWCA's aquatic survey indicate that
no Federally or State aquatic species of concern occur in the Project area. Because there is no evidence of
rare species occurring within the survey areas, SWCA is not providing any management
recommendations beyond the typical water quality best management practices.
Fish species composition differed between pond and creek habitats. Only five fish species were observed
within the ponds surveyed,versus 11 species within creek habitat.Bluegill was the most common species,
occurring in all ponds and all creeks surveyed. This common sunfish species,as well as three other
species observed within pond habitats(redbreast sunfish, largemouth bass, and spotted bass)were also
observed within some stream sections. Pumpkinseed was only observed in South Creek Reservoir.
While there is no exceedance of North Carolina water quality standards for Class C waters for waters to
be discharged from both South Reservoir and the pit lake, several constituents may impact aquatic life
identified within Kings Creek without equilibration in South Reservoir,notably temperature,dissolved
oxygen and dissolved sulfide. Based on the available data,residence time in South Reservoir as well as
the drop over rip rap from the culverts to the discharge point in Kings Creek will support equilibration of
these constituents to levels appropriate for discharge.
4 CONCLUSION
Based on the existing conditions detailed in this report,the following design considerations are
recommended:
• Dewatering flows from the existing mine pit shall not exceed 3,500 gpm(7.80 cfs).
• Based on the estimated volume of water to be discharged to Kings Creek,the anticipated
discharge rate, and the allowing for regular maintenance of the system, dewatering is anticipated
to take between 10 and 24 months to complete.
• Water quality sampling and analysis,combined with geochemical modeling is ongoing to further
evaluate potential impacts to Kings Creek through this proposed action.
If the proposed discharges into Kings Creek meet the recommendations within this report,then the
requirements set forth regarding the stream stability and water quality will be met without additional
analysis. However,modifications to the proposed flow regime may require that this analysis be revised.
Some modifications that would require this analysis to be revised include:
• Changes in measured water quality concentrations,performed annually.
• Significant changes in the watershed that result in increased runoff to the Project Reach.
The above modifications may result in the assumptions within this report becoming invalid.
The computations within this report will need to be revisited if any of the above conditions become
apparent as the project moves forward.

Laboratory and field data on critical shear stress required to initiate
movement of grains(Leopold.Wolman,do~tiller. 1%4). The solid line is the
Shields curve of the threshold of motion; transposed from the 9 versus Rg
form into the present form, in which critical shear stress is plotted as a
function of grain diameter.

Aquatic Habitat Assessment Report for the Kings Mountain Lithium Mine, Cleveland County, North Carolina
October 2022
1 INTRODUCTION
On behalf of Albemarle Corporation(Albemarle), SWCA Environmental Consultants(SWCA)conducted
an aquatic habitat assessment for the Kings Mountain Lithium Mining Project(Project)located in
southeastern Cleveland County,North Carolina. The primary objective of the assessment was to
determine the aquatic faunal assemblage of the ponds and streams within the Project area.Additionally,
state-listed species with the potential to occur were surveyed for during this assessment. These data will
be used to understand the potential impacts to the aquatic systems that might occur during mine
construction and operations,including the discharge of water to Kings Creek during pit dewatering.
1 .1 Location
The Project is on private land owned or leased by Albemarle and consists of approximately 1,403 acres
(Project area). The Project is located approximately 2 miles south of downtown Kings Mountain,North
Carolina, and is located on the U.S. Geological Survey(USGS)Kings Mountain,North Carolina,
7.5-minute quadrangle(Figure 1). The Project area is divided by Interstate 85 (I-85),with the main parcel
on the north side of the highway(Main Site—North of I-85)and two smaller parcels on the south side of
the highway(Main Site—South of I-85 and Albemarle East Property). The main parcel is bordered by
South Battleground Avenue (Highway 216),Parkgrace Road, and Tin Mine Road to the west; Quarry
Road to the north; and 1-85 to the south and east.
1 .2 Project Area Description
The main parcel is mostly developed/disturbed and includes Albemarle's lithium salts and compound
processing facility and Albemarle's Global Technical Center. The west side includes an active drive-in
theater,retired paper processing plant, and recreational vehicle(RV)campground. Five utility
rights-of-way(ROWS) cross the northern and central portions of the parcel. The parcel directly south of
I-85 is mostly undeveloped. The Kings Mountain Gateway Trail goes around the northern and eastern
boundaries of this parcel with an access point and parking area off Galilee Church Road. Additionally,
three utility ROWS cross the parcel running northeast—southwest. The easternmost parcel(Albemarle East
Property), east of York Road, is undeveloped with only a few unpaved roads for access.Undeveloped
land in the three parcels consists primarily of forest and wetland habitats. The Project area is surrounded
by residential, commercial,and industrial development to the north,west, and south(Figure 2). The
Martin Marietta mine borders the Project area to the north. To the east is primarily undeveloped land
associated with Crowders Mountain State Park.
The Project area is located within the Kings Creek(hydrologic unit code [HUC] 0305010509) and
Buffalo Creek(HUC 0305010508)watersheds of the Broad River Basin(North Carolina Department of
Environmental Quality [NCDEQ] 2022). The Broad River is located approximately 15 miles
west-southwest of the Project area. Kings Creek, a tributary of the Broad River,runs through the Project
area.According to the USGS Kings Mountain 7.5-minute quadrangle maps,the headwaters of Kings
Creek originate approximately 0.75-mile northeast of the Project area.
There are also on-site resources named by Albemarle for Project purposes. These are all man-made
features including the Pit Lake,Mud Pond 1,Mud Pond 2,No. 1 Mill Pond,Executive Club Lake, South
Creek,and South Creek Reservoir. Pit Lake is a mining pit that has filled with water since mining ceased.
Mud Pond 1,Mud Pond 2,and Mill Pond No. 1 are isolated ponds on the Albemarle Main Site—North of
1-85. South Creek is a south-flowing stream on the western portion of the Albemarle Main Site—North of
1-85 with the South Creek Reservoir making up the dammed-up portion that eventually empties in Kings
Creek to the east. Executive Club Lake is an old tailings pond on the Albemarle Main Site—South of 1-85
that has an outflow channel to Kings Creek. Small tributaries contribute flow to this lake.

2 METHODS
2.1 Desktop Analysis and Previous Surveys
A preliminary desktop analysis was completed for the Project prior to field surveys by using a
combination of existing information obtained from available public sources, including published
literature, online databases, and geographic information system(GIS)data. The following publicly
available data sources were used to characterize the lake,pond,wetland, and stream habitat within the
Project area that would be surveyed:
• North Carolina Natural Heritage Program's(NCNHP's)An Inventory of the Significant Natural
Areas of Cleveland County, North Carolina(NCNHP 2003)
• NCNHP List of Rare Animal Species of North Carolina(NCNHP 2020).
• NCNHP Element Occurrences,Natural Areas, and Managed Areas Within a One-mile Radius of
the Project Area(NCNHP 2022a)
• NCNHP Species/Community Search for Cleveland County(NCNHP 2022b)
• North Carolina Wildlife Resources Commission(NCWRC)Protected Wildlife Species of North
Carolina(NCWRC 2021)
• U.S. Fish and Wildlife Service(USFWS)Information for Planning and Consultation Species List
for Kings Mountain Area(USFWS 2022a)
• USFWS National Wetland Inventory(USFWS 2022b)
• USGS National Hydrography Dataset(USGS 2019)
SWCA previously conducted a wetland and waterbody delineation in February and March 2022 (SWCA
2022a). Observations from these surveys were also used when determining suitable habitat and sampling
areas for the aquatic surveys. SWCA focused aquatic survey efforts on streams with potential suitable
habitat for listed species, as well as all larger ponds and reservoirs.
Some areas,including small tributary streams,were not surveyed due to minimal habitat or unsuitable
habitat for listed species. Upstream aquatic surveys were terminated at points where declining flows, fish
density, and fish diversity rendered further sampling unlikely to add to the understanding of the aquatic
environment, in terms of either species diversity or detecting sensitive species.
Aquatic surveys continued downstream until terminated due to flooding(from beaver dams)or at the
Project property boundaries. Flooded areas were surveyed to obtain a representative species diversity but
terminated where pools became too deep to electroshock(approximately 1 meter deep). Further sampling
of flooded areas with hoop nets was deemed unlikely to add to the understanding of the aquatic
environment, as the species transition from the fast-moving aquatic environment in the upper portions of
Kings Creek to the typical pool/slow-water environment had already been noted from the electroshocking
surveys.
The publicly available data sources were also used to determine a short list of aquatic species of concern
with the potential to occur in the Project area(Table 1). Seven state-listed aquatic species were identified
as having the potential to occur in Cleveland County, although none were listed as state threatened or
endangered.No federally listed aquatic species were identified as having the potential to occur.More
detailed species descriptions are provided under separate cover in the Federally and State-Listed Species
Report for the Kings Mountain Lithium Mine, Cleveland County, North Carolina(SWCA 2022b).

2.2 Field Surveys
SWCA used three primary methods to assess the aquatic habitats observed within the Albemarle
properties: trapping fish within pond habitats, electrofishing in streams, and conducting visual and tactile
surveys of streams for aquatic macroinvertebrates(primarily freshwater mollusks and crayfish). Aquatic
surveys were conducted August 22 through August 26,2022.
All collected animals were identified to the species level and released at their capture location. Additional
data including animal lengths and sexual characteristics were collected.
2.2.1 Baited Minnow and Hoop Trap Surveys
SWCA deployed baited minnow traps and hoop nets at five locations on the Main Site—North of I-85
(No. 1 Mill Pond,Mud Pond 1,Mud Pond 2, South Creek, and Pit Lake) and one location on Main Site—
South of I-85 (Executive Club Lake) (Figure 3;Appendix A).A total of 61 minnow traps and 21 hoop
nets were deployed during the survey period. Traps were baited using Purina Aquamax dry fish food.
Minnow traps were fully submerged in the water and used to capture fauna larger than the 1/4-inch mesh
and smaller than the 1-inch opening of the traps.Hoop nets were partially submerged in water and used to
capture fauna larger than the 1/4-inch mesh and smaller than the 4-inch opening.All traps were checked
the day after they were placed, and all animals were identified and measured before being released at the
same location.

2.2.2 Electrofishing Surveys
SWCA conducted assessments of four streams within the Albemarle properties(Appendix A; see
Figure 3;Appendix A): South Creek,located on the Main Site—North of I-85; Kings Creek,located on
the Main Site—North of I-85 and Main Site—South of 1-85; and two unnamed streams located on the
Albemarle East Property(referred to as Wellman Stream 1 and Wellman Stream 2).
SWCA used a Smith-Root LR-24 backpack electrofishing unit to perform electrofishing sampling within
the stream habitat on the Albemarle properties. The electrofishing sampling started at the downstream
portion of a site,then moved upstream. Two netters were located on either side of the operator.Affected
animals were captured with hand nets and collected in plastic buckets.
Fourteen sites representing a total of 2,426 meters of stream habitat were sampled.
2.2.3 Aquatic Macroinvertebrate Surveys
SWCA conducted assessments of the four streams listed above.Due to the shallow waters of all four
streams, SWCA did not use snorkeling equipment,but rather conducted visual and tactile surveys by
wading each of the 14 stream segments within which electroshock fishing had been conducted. In
addition, in several cases, SWCA surveyed beyond the electroshocking segments within the main
Albemarle property. These sections are designated with an S-number in Figure 3 and the maps in
Appendix A. During these surveys,two or three biologists visually scanned the stream bottom for live
freshwater mussels, snails,and crayfish, as well as other evidence of these taxa, such as shells. The
biologists also conducted tactile searches in areas with soft substrates or where the water was too turbid
for visual surveys.
Fourteen sites representing a total of 2,712 meters of stream habitat were sampled
3 RESULTS
3.1 Minnow and Hoop Traps
In total, 82 baited traps sets were used for sampling the Project area. This included 21 hoop net sets and
61 minnow trap sets. The baited traps had an average sampling time of 20.51 hours per trap.
No threatened or endangered species were trapped during the survey period. In total, 957 fish were
trapped at the Project site using minnow traps and hoop nets. Bluegill(Lepomis macrochirus)was the
most common fish species, accounting for 98.4%of observations. Other fish species trapped included the
redbreast sunfish(Lepomis auritus), spotted bass(Micropterus punctulatus),largemouth bass
(Micropterus salmoides),and pumpkinseed(Lepomis gibbosus). Other fauna captured in traps included
mud turtles(Kinosternon subrubrum),musk turtles(Sternotherus odoratus),painted turtles(Chrysemys
picta), a yellow-bellied slider(Trachemys scripta scripta),a northern water snake(Nerodia sipedon), and
bullfrog tadpoles and adults(Lithobates catesbeianus).
A complete list of fish species encountered in ponds is provided in Table 2. All species have an
International Union for Conservation of Nature (IUCN) status of Least Concern,which is a species that
the IUCN has classified as not being a priority for species conservation because the species is still
abundant in the wild. They are not endangered,vulnerable,threatened,near threatened, or conservation
dependent(IUCN 2022);Additionally,none are listed by the USFWS under the Endangered Species Act,

and none are state listed. Detailed maps of trap locations are in Appendix A, and photographs are in
Appendix B.
3.2 Electrofishing Sampling
Fourteen stream sections (El—E14)were sampled using backpack electrofishing surveys. South Creek
was represented by stream sections E1 through E4.Kings Creek was represented by stream sections E5
through E8.Wellman Stream 1 was represented by stream sections E9 and E10,and Wellman Stream 2
was represented by stream sections El 1 through E14. Each site had an average sampling/shocking time of
14.4 minutes.A total of 2,426 linear meters of stream habitat were sampled. Each electrofishing site was
sampled using a single pass only in order to sample the largest area possible. General species
composition, abundance, and distribution data were collected in order to identify possible species of
concern.
In streams, a total of 895 fish were observed from 11 species(see Table 2). The most abundant species
observed in the stream habitats was the creek chub(Semotilus atromaculatus),which accounted for
5 1.1%of observed individuals. In-stream riffle/runs were dominated by creek chub,bluehead chub
(Nocomis leptocephalus),and rosyside dace(Clinostomus funduloides).Pool structures in the streams were
dominated by bluegill and redbreast sunfish. Less common,but also observed in pool structures with
woody debris or other cover,were spotted bass and warmouth(Lepomis gulosus).
All species have an IUCN status of Least Concern(IUCN 2022);none are listed by the USFWS under the
Endangered Species Act, and none are state listed by the NCWRC (see Appendices A and B).

October 2022
3.2.1 Aquatic Macroinvertebrate Surveys
Fourteen sites representing a total of 2,712 meters of stream habitat were sampled.No native bivalves
were observed in the four streams surveyed. The only freshwater bivalve observed was Asian clam
(Corbicula sp.). This is an introduced species of mollusk that is considered invasive. Asian clams were
observed only on the Albemarle East Property,in Wellman Stream 2. The presence of Asian clams in
Wellman Stream 2 suggests this stream may be capable of supporting native bivalve species as well.No
aquatic snail species were observed in the four streams surveyed. One unidentified crayfish was observed,
but not caught, in Kings Creek.Numerous individuals of crayfish were observed and captured in the two
streams within the Albemarle East Property.All crayfish photographed are members of the Cambarus
(Puncticambarus) sp. C(acuminatus)complex.No species within this complex are considered rare.
4 SUMMARY AND CONCLUSIONS
The main aquatic habitat types within the Project areas are ponds and creeks. Pond substrate was
generally soft silt or muck.Minnow traps and hoop nets were placed at varying depths in ponds to
diversify habitat and capture fish from different life stages. The surveyed creeks were generally less than
3 feet in depth and averaged closer to 1 foot in depth. Creek substrate ranged from soft silt and muck to
combinations of sand, gravel, cobble, and some boulder. The soft substrates were primarily found in areas
of beaver impoundment.
Fish species composition differed between pond and creek habitats (see Tables 2 and 3). Only five fish
species were observed within the ponds surveyed,versus eleven species within creek habitat. Bluegill was
the most common species, occurring in all ponds and all creeks surveyed. This common sunfish species,
as well as three other species observed within pond habitats(redbreasted sunfish, largemouth bass, and
spotted bass)were also observed within some stream sections.Pumpkinseed was observed only in South
Creek Reservoir.
Differences in species composition were observed between creeks within the Main Site and the Albemarle
East Property.Nine fish species were observed in South Creek and/or Kings Creek within the Main Site,
and nine fish species were observed in creeks surveyed in the Albemarle East Property. Species were
observed in South Creek(five species),Kings Creek(six species),Wellman Stream 1 (five species), and
Wellman Stream 2(seven species). White crappie(Pomoxis annularis)and largemouth bass were
observed in the Main Site only, and rosyside dace and flathead catfish(Pylodictis olivaris)were observed
only in the Albemarle East Property.All other species were observed in both survey areas. Another
notable difference between the creeks of the Main Site versus those of the Albemarle East Property is the
apparent low density of crayfish within the Main Site (only one individual observed) in contrast with the
numerous crayfish observed within both creeks on the Albemarle East Property. This observation is likely
due residential and mine development within and surrounding the Main Site and its aquatic resources,
while the Albemarle East Property has remained undeveloped.
Overall South Creek showed very low species diversity above the lower sections that were flooded by
beaver dams,with the upper stream sections being composed of only creek chub. King's Creek had a
significant fish barrier(a low water dam), and no species were observed above the dam except a single
mosquito fish. Below the dam, some species diversity was observed including bluehead chub,bluegill,
redbreast sunfish, spotted bass, and mosquito fish. The Albemarle East Property streams had the highest
species diversity longitudinally across entire stream sections. Sampled sections demonstrated classic
species compositions associated with pool vs.riffle run habitats,with deeper pools containing bluegill,
warmouth,and occasionally spotted bass. Riffle/run habitats contained primarily chub and dace species

with some bluegill. Larger-bodied creek chub and rosyside dace were also found in pools with associated
woody debris or other cover.
All species of fish,crustaceans, and bivalves encountered during surveys are listed as Least Concern by
IUCN. The results of SWCA's aquatic survey indicate that it is unlikely that federal or state-listed aquatic
species of concern occur in the Project area. Because there is no evidence of rare species occurring within
the survey areas, SWCA is not providing any management recommendations beyond the typical water
quality best management practices.
