Dear Sir:
In response to the April 27, 2023 NC DEQ Division of Water Quality Permitting's Industrial Permitting
Unit Additional Information Request (ADI), Albemarle submits herein all information requested.
ADDITIONAL INFORMATION REQUESTED
1. Delegation of Authority for Reports to be Filed: Based upon the information supplied it does not
appear that Albemarle has delegated state application(s) authority to Mr. Fisher. A solution would
be to add to the existing list in the letter accompanying the PA a line item for the "State of North
Carolina. "
Albemarle Response: Delegation of authority will be Jose Fernando Rodriguez, Mine Site
Director/GM. Attachment 1 includes the delegation of authority for the State of North Carolina, as
well as the Form 1 and Form 2E signatory pages.
2. PFAS Questionnaire: Please complete the PFAS questionnaire as Attachment 1 herein and
submit with the additional information. This request is based upon information supplied to date,
specifically related to chlorinated organics.
Albemarle Response: A completed PFAS Questionnaire has been included with this response to
comments in Attachment 2.
3. Form 2D Data Required: Information (e.g. studies) and data provided to date regarding
characteristics of the discharge is not sufficient enough to enable Division to determine limits and
monitoring frequency for an NPDES permit. To address this please provide one-time sampling
results for all missing pollutants in EPA's Form 2D, tables B, C and D from submitted
application. Analysis for compounds in table E is necessary to determine if such contaminants
might be present. Sampling from various elevations of Pit Lake due to its depth is essential to
provide representative samples of possible pollutants in the proposed discharge during the
anticipated project duration. Please closely adhere to instructions contained in EPA's form 2D for

AALBEMARLE (1)

4250 Congress Street, Suite 900 Telephone: [phone]
Charlotte, North Carolina 28209 www.albemarle.com
presentation of results. Sampling shall be conducted according to sufficiently sensitive test
procedures (i.e., methods) approved under 40 CFR 136 for the analysis of pollutants or pollutant
parameters.
Albemarle Response:
The accumulation of storm water in Pit Lake did not occur "during manufacturing or processing" and
no processes or operations have been conducted in Pit Lake in 40 years. All dewatering activities will
occur prior to processes and operations re -starting on -site. However, as requested by NCDEQ, even
though Form 2D addresses discharges of process water while the Pit Lake contains nonprocess water,
Form 2D has been included with this response to comments in Attachment 3.
A one-time sampling event for all missing pollutants in EPA's Form 2D, tables B, C and D has been
included as an attachment to Form 2D. Samples were collected at various depths in the Pit Lake to
provide a complete profile of the water column. On Form 2D, samples from a depth of 150ft were
also included. These results do not take into account any mixing or dilution that would occur during
withdrawal and is representative of only a small section of the total volume. The remainder and
majority of the discharge will have lesser values as you can see in the attachment to Form 2D.
During this one-time sampling event, water quality data was collected from depths of 10, 50, 100, and
150 feet to provide a profile of the water quality throughout the Pit Lake. Table 1 shows the
percentage of Pit Lake Volume that each of the depths represent.

4. SIC/NAISC Codes and Pre -Mining Dewatering Activities: SIC /NAISC codes provided in
EPA's form I section 3 must be reflective of the characteristics of the discharge. Based upon the
information and data provided the discharge resulting from dewatering of Pit Lake is anticipated
to occur prior to Lithium mining activity. Please revise the SIC /NAISC codes accordingly.
Albemarle Response: Because the proposed temporary discharge is a dewatering event prior to
starting lithium mining activities, the SIC and NAICS codes that best reflect dewatering activities are
SIC Code 1799 — dewatering contractors and NAICS Code 238910 — dewatering contractors. The
forms have been updated to reflect this.
5. Dewatering Time Period Clarification: Please provide clarification as to why the EAA report
provided reflects dewatering is anticipated to occur for eight (8) months and yet the cost analysis
provided reflects a two (2) year period. If this apparent discrepancy is an error, please correct
and resubmit the corrected information.

AALBEMARLE (1)
Albemarle Corporation
4250 Congress Street, Suite 900 Telephone: [phone]
Charlotte, North Carolina 28209 www.albemarle.com
Albemarle Response: The 8-month timeline is based on a continuous discharge at the maximum
discharge rate of 3500 gpm and was provided as the best -case and most -efficient timeline scenario
The two (2) year time frame was based on an average discharge rate of 2000-2500 gpm to account for
rain events and to accommodate maintenance activities. The expected length of time to dewater the
Pit Lake is 2 years.
6. Dewatering of Pit Lake and Groundwater: Since many of the elevations of Pit Lake are lower
than the existing groundwater table it is safe to assume that groundwater will flow into the lake
area during dewatering. Has this additional water source been factored into the anticipated time
period of eight (8) months or two (2) years for dewatering? If not how much more time will be
required to completely dewater Pit Lake? In addition, if more time is required to dewater Pit Lake
how will this affect the existing time schedule for recommencement of Mine's operation and
requirements of the related discharge permit (e.g., NPDES permit)? Please provide a plan for
such transition.
Albemarle Response: Based on Albemarle's extensive groundwater monitoring, Pit Lake monitoring,
and modeling, groundwater flow into the Pit Lake is minimal, compared to the approximate one
billion gallons of water in the Pit Lake and the stormwater inflow. This additional water source was
factored into the anticipated timeline for dewatering. Ongoing groundwater studies indicated that
groundwater inflow to the pit would increase as the hydraulic gradient towards the dewatered
pit increases. At the end of the dewatering process, it is projected that the maximum
groundwater inflow into the pit will reach approximately 150 gpm. This amount, with an
additional 20% contingency, has been incorporated into the lake dewatering timeline
estimate.
Albemarle will timely apply for the applicable permits for mine operation discharges to facilitate a
seamless transition between this temporary discharge and the future operational discharges. The
temporary discharge permit is only for the dewatering of the pit, prior to operational activities. Once
operation commences, the temporary discharge permit will be terminated, and the in place future
operational discharge permit will become active.
7. Dewatering of Pit Lake and Water Quality Standards: What measures (e.g. specific treatment
alternatives, such as pH control and aeration) will be employed to ensure that discharge of Pit
Lake will not cause: (1) Water quality standards violations related to pH, DO; (2) and / or
negatively impact (e.g. compromise) aquatic life do to identified parameters; such as, ammonia,
dissolved lithium?
Albemarle Response: Albemarle has conducted extensive sampling of the water in the Pit Lake and
determined that the pit water meets North Carolina Class C Standards without treatment. These
sample results were provided to NCDEQ with Albemarle's application. (December 13, 2022)
In an effort to provide reasonable assurance that protection of the environment and in response to
potential community concerns, Albemarle determined that treatment may be desirable at various
times during the dewatering process for hydrogen sulfide and ammonia. Notably, neither of these

AALBEMARLE (1)
Albemarle Corporation
4250 Congress Street, Suite 900 Telephone: [phone]
Charlotte, North Carolina 28209 www.albemarle.com
constituents have NCDEQ Class C standards, but treatment for hydrogen sulfide will mitigate
potential odor concerns, and treatment for ammonia will mitigate potential aquatic life impacts.
Based on prior sampling, pH is not expected to create a water quality concern during dewatering and
the treatment for hydrogen sulfide and ammonia is expected to buffer the pH within NCDEQ Class C
standards (i.e., between 6 and 9).
Low dissolved oxygen (DO) occurs at certain depths of the pit; however, we expect DO will increase
at lower levels as the pit surface is drawn down. Water from the pit will enter South Creek reservoir
prior to being discharged to Kings Creek, which will provide further mixing and oxygenation to
improve water quality. Lastly, the chemical oxidation treatment for hydrogen sulfide and ammonia
will also increase oxygen in the discharged water.
Samples of the Pit Lake will be taken throughout the dewatering process to determine if additional
treatment may be required for constituents of concern. Real-time and grab samples will be collected
and analyzed prior to discharge, and Albemarle will comply with any sampling requirements and
effluent limits included in the final permit. If discharge monitoring indicates elevated parameters that
could affect water quality in Kings Creek, the water will be returned to the Pit Lake and the treatment
plant will be inspected and modified as necessary to ensure discharges meet water quality standards.
Additional information about the treatment system is provided in response to number 8., below.
8. Potential Downstream Impacts do to Dewatering: Based upon information provided to date, the
projected flow regime (e.g. volume and duration) will likely negatively impact creek stability and
water quality. Thus, please provide details on proposed treatment alternative(s) evaluation
demonstrating the facility will be capable of meeting water quality standards or limits at all times
accounting for potential variables that may exist during dewatering?
Albemarle Response: All water will meet discharge requirements at all ranges of flow and
duration. As stated in response to Question 7, Albemarle will treat water during dewatering. The
water treatment system will have process controls to adjust to changing water quality and flowrates
while maintaining compliance with the discharge permit.
Albemarle evaluated several alternatives to effectively treat the Pit Lake water, the final selected
alternative utilizes two stages of chemical oxidation, media filtration, followed by membrane
filtration. The water treatment system will be conservatively designed to treat maximum
concentrations of analytes identified in the Pit Lake.
In addition, the flow rate of the discharge will average 2,000-2,500 gallons per minute to maintain
Kings Creek channel integrity. Pit dewatering flow rates will be monitored in real time to ensure safe
operation and to maintain a flow rate that is suitable to the capacity of Kings Creek, particularly
during rain events.
9. Dewatering and "Minor Increase' : Please explain how proposed dewatering is a "minor
increases inflow due to the mine pit dewatering" and how this "is not expected to adversely
impact the banks of Kings Creek"? Based upon information provided to date the anticipated flow

AALBEMARLE (1)
Albemarle Corporation
4250 Congress Street, Suite 900 Telephone: [phone]
Charlotte, North Carolina 28209 www.albemarle.com
regime (e.g. volume and duration) is far above the critical flow of the stream (e.g. 7Q10), thus the
potential exist for significant ecological impacts to downstream waterbodies. Lastly, has
Albemarle /Kings Mountain conducted a bioassay of the creek; if so please provide that
information? Please note that responses provided may necessitate ADI request(s).
Albemarle Response: A request was submitted on June 1, 2023 to USGS for the determination
of the Annual 7Q 10 streamflow for the onsite portion of Kings Creek. A response was
received on June 14 from USGS that the Annual 7Q 10 streamflow for Kings Creek as it
leaves Albemarle's property is approximately 0.39 cfs. SWCA opinion is that this Annual
7Q 10 estimate is not representative of current baseflow conditions for Kings Creek within
the vicinity of the proposed discharge location. The USGS also reported that the Average
Annual Discharge for this portion of Kings Creek is approximately 2.7 cfs. In May of 2022,
Albemarle installed a stream gage at a v-notch weir in Kings Creek as part of the original
mining operations at the Site. Using this observed data, the average daily streamflow flowing
over the v-notch weir was calculated to be 2.59 cfs.
These higher baseflow observations are likely a result of a permitted discharge from the
aggregate mining operation owned and operated by Martin Marietta, which is located just
upstream of the Site. As mentioned in Section 2.2.1 of the Kings Creek Stability and Water
Quality Assessment (Report) submitted with the permit application ( December 13, 2022),
Martin Marietta is permitted to discharge 2,250 gpm (5.01 cfs) into Kings Creek according to
their active mining permit (23-02).
Because of the corroboration with the reported Average Annual Discharge with the measured
baseflow observations, the HEC-RAS model was updated using the baseflow assumption of
2.59 cfs. The velocity and depth results of the analysis are as follows:
Existing Velocity
(fps)
Proposed Velocity

Average

0.95
Although this increase in velocity and depth during baseflow conditions is significant, ranging from
8% to 250%, it can be safely assumed that the Kings Creek channel will remain stable throughout the
dewatering process. Figure 8-3 of the NRCS Stream Restoration Design National Engineering
Handbook indicates that Kings Creek, which was classified as a medium gravel stream with a D50 of
15 mm (see Section 2.3 of the Report), would remain stable for flows of 5 fps at a depth of 5 ft. The
maximum baseflow depth and velocity expected during the maximum dewatering flow rate of 3500
gpm is 3.84 fps at a depth of 2.54 ft, well below the critical threshold for a stream of this nature.

Furthermore, as mentioned in Section 2.4 of the Report, attached to the permit application as Form 2E
Section 7.1 Attachment 1, the BEHI & NBS analysis that was conducted to determine the stream
bank erosion potential for Kings Creek determined that the stream banks within the vicinity of the
Site have "very low" to "low" erosion potential, largely due to the existing stream bank
characteristics such as vegetation, root depth & density, bank angle, and bank height ratio. This bank
erosion assessment further confirms the assumption that Kings Creek will be stable throughout the
duration of Albemarle's dewatering operations.

PFAS Questionnaire
1. Do you use any material or products (directly or indirectly) in your operations that contain
fluorinated chemicals? If so, please identify what materials or products contain fluorinated
chemicals.
Albemarle Response: No, the dewatering of the Pit Lake will not use material or products that contain
fluorinated chemicals.
• Please also address if you have any historical conditions and/or information for past
practices at the site related to fluorinated chemicals?
Albemarle Response: There is no historic conditions or information for past practices at the site
related to fluorinated chemicals.
2. Will your facility formulate or create products (directly or indirectly) which contain
fluorinated chemicals? If so, please identify the specific fluorinated chemicals that may be
formulated or created.
Albemarle Response: No, the facility will not formulate or create products which contain fluorinated
chemicals.
3. Will your facility produce solid waste, liquid waste, wastewater effluent, or other waste
containing fluorinated chemicals? Please be as specific as possible to describe what
fluorinated chemicals may result in the facility's wastewater, solid waste, or sludge.
Albemarle Response: No, the facility will not produce solid waste, liquid waste, wastewater effluent,
or other waste containing fluorinated chemicals.
4. Are there processes or operations that use equipment, material, or components that contain
PFAS chemicals (e.g., surface coating, clean room applications, solvents, lubricants, fittings,
tubing, processing tools, packaging, facility infrastructure)? Could these activities result in
fluorinated chemicals being discharged as products, or by-products (i.e., through leaching,
chemical process, heat treatment, pressurization, etc.)?
Albemarle Response: No, the process of dewatering will not include the use of equipment, material,
or components that contain PFAS chemicals
S. List CAS numbers of all known or believed present fluorinated compounds from the questions
above. Please provide descriptions, quantities, and whether there are any unknowns related to
the above questions.
Albemarle Response: There are no known or believed present fluorinated compounds at the site.

6. Are there other facilities or operations in the U.S. or internationally that are identical to or
may use processes similar to the facility in North Carolina? If so, please provide facility
identification information and wastewater characterization including all PFAS compounds?
Albemarle Response: While dewatering mine pits is common practice in the U.S. and internationally,
the Albemarle Kings Mountain temporary pit lake dewatering activities is unique because of the lack
of process water. No process or operations have been conducted in the Pit Lake in 40 years, and the
proposed dewatering will occur prior to operations commencing again.
7. Additionally, have any PFAS analytical results been collected with any analytical test method
similar to the following EPA Test Methods. Are any of the fluorinated compounds listed in one
of the following methods and can you provide us with data resulting from these test methods?
■ Methods 533 & 537.1 (drinking water)
■ SW-846: Method 8327 (water)
■ Draft Method 1633 (water, solids, tissue)
Albemarle Response: PFAS sampling of the Pit Lake was conducted on March 21, 2023 at three
locations. The sample depth at all three locations was 1 Oft below the water surface. Analytical results
as well as a map of monitoring locations have been included with this questionnaire.

MEMORANDUM
DATE: March 14, 2023
TO: Morgan Warren
FROM: Sam Billin, P.E.
SUBJECT: Water Treatment Design Basis Memorandum
REFERENCE NO.: Albemarle Pit Dewatering Analysis, 125.01 137 Revl
OBJECTIVE
The purpose of this memorandum is to define the Basis of Design for a pit dewatering water
treatment system to be located at Albemarle's Kings Mountain mine.
The purpose of treatment is to lower the concentration of ammonia and sulfide species and other
constituents of concern (COCs) in the dewatering flows and enable discharge of treated effluent
to South Creek Reservoir. South Creek Reservoir discharges into Kings Creek. Kings Creek forms
part of the Broad River watershed deemed by the NC DEQ as Class C per ERM's report. Kings
Mountain (KM) pit water exceeds NC DEQ Class C reference values for various constituents.
DESIGN BASIS
Discharge Flow Rate
The requested discharge effluent flow rate to South Creek Reservoir is 2,000 gpm. Linkan will
perform a series of desktop models to predict flows based on achievable recovery. The objective
of the project is to treat roughly 1,300,000,000 gallons of retained pit water so as to facilitate mine
development. This effort is estimated to take between 15 and 16 months at the designated flowrate.
Location
Albemarle has recommended that the WTP be placed on the east side of the pit at the bottom of
the existing ramp or adjacent to the pavilion. Consideration of placing the WTP higher on the
bench southwest of the pit was abandoned after consideration of the blasting requirements to lay
in a pipeline line to the barge pumps.
Discharge Water Quality Standards
A permit application to discharge has been filed in November 2022. A permit has not been issued.
For this design basis memorandum, Linkan Engineering will use the NC DEQ Class C reference
values to assess treatment options. The NC DEQ Class C and In -Stream Target values are indicated
in Table 1 and are compared to the water quality results from the KM pit.

Office: 775.777.8003

Feed Water Quality
The pit water will provide influent to the treatment system. Work has been conducted by SRK and
Linkan to sample and determine the current water quality from the pit. It was identified that at a
depth of 130-140 ft, water conditions vary from higher elevations. The focus of the design basis is
treatability at these depths. It is anticipated that upper elevations of water contain fewer
contaminants and that the full treatment may not be required on the entire water column.
We also anticipate that the lower reaches of the pit (150-165 feet) will be a difficult mix of settled
solids, sludge, organic matter, and other deposits. We anticipate that additional efforts and/or
changes to the treatment system may be required as we reach the end of the project and need to
modify to accommodate this last volume of water. Based on the supplied Stage/Storage curve, this
last 15 feet of water (150-165 feet) represents about 17 million gallons or 1.3% of the total project
volume, based on reported pit elevation of 816.55 ft as of February 6th, 2023. Accordingly, the
basis of design will focus on the 0-150 feet of depth at this time.

CONTAMINANTS OF CONCERN
Based on the bench work of the 130 ft sample and the on -going 140 ft sample test, COCs have
been identified as sulfide, ammonia and manganese. While ammonia is not listed in the NC DEQ
limits, it is anticipated that the final discharge permit will employ a discharge standard based on
EPA's freshwater quality criteria to protect aquatic organisms. Table 2 identifies the likely
constituents requiring treatment.

Based on the in -situ sampling, the basis of design shall be 24.5 mg/L sulfide for all waters ranging
from 0 to 150 feet. The process shall be designed to allow bypass around any single treatment
process step in the event that step is not needed for water from that specific elevation.

Additional Testing
A sample of 140 ft pit water is currently being evaluated as per the treatment process described
herein at Linkan's Elko facility. All these works are in support of this design basis. Analytical
results will be presented when available.
MANAGEMENT OF TREATMENT WASTES
All liquid waste generated by the treatment system is anticipated to be pumped or gravity drained
back to the dewatering pit furthest away from the floating pump station. This liquid waste can be
comprised of periodic discharges of suspended solids and cleaning wastes from the water treatment
equipment.
Unit processes waste characterization are qualitatively described below:
• Media filter backwash waste is anticipated to be a combination of suspended particulate
from pit water larger than 20 µm in size and elemental sulfur from the oxidation of
hydrogen sulfide. Solids in the backwash will undergo additional filteration through
geobags. Filtrate from the geobags will be returned to the pit. The geobags will be
managed by Albemarle.
• Hollow fiber (HF) filtration backwash waste is anticipated to be suspended particles from
pit water larger than 0.01 µm in size and metal oxides from oxidation process. When
required, cleaning solutions consisting of high pH (sodium hydroxide and sodium
hypochlorite) and low pH (Citric acid) will be used to recover HF performance.
Linkan has not characterized the existing suspended solids in the water or the settled solids on the
pit floor. We understand these to be predominantly organics because of the pit flooding natural
vegetation. Note that all solids will be returned to the pit and settled. Management of the floor
slimes is not yet developed and beyond the scope of this design basis.
Metal hydroxides captured by the ultrafiltration will be comingled with the organic solids from
the pit floor. These solids should be subjected to RCRA hazard evaluation when they can be
secured. However, we do not anticipate that any individual metals concentration will exceed the
applicable RCRA standard for the 8 priority metals required for land application at a Class C
landfill.
All ammonia will be converted to gaseous nitrogen via Breakpoint Chlorination. Nitrogen gas will
be released from the top of the oxidation tank to the atmosphere.
PRELIMINARY ASSESSMENT
A preliminary Process Flow Diagram is attached that details the anticipated water treatment
process. Based upon the aforementioned bench testing and additional work, the pit water will
undergo physical chemical process. Pit water will be treated with a contingent coagulant (Ferric
Chloride or Aluminum Sulfate) to aid in the filtration process and oxidized with an estimated 215
mg/l of Sodium permanganate (-1220 gallons of 40% sodium permanganate per day to discharge
2,000 gpm) to convert hydrogen sulfide to elemental sulfur for removal in the media filters. The
filtrate of the media filters will be oxidized with an estimated 42 mg/1 of Sodium Hypochlorite
(-910 gallons of 12.5% of sodium hypochlorite per day to discharge 2000 gpm) to remove
ammonia and oxidize fugitive manganese in the resulting water. The final step of treatment is
0

hollow fiber (HF) membrane to ensure particulate solids are removed from discharged water
including oxidized manganese.
The discharge criteria limit the allowable chloride in the effluent to 230 mg/L (NC DEQ). Based
on the existing chloride in the raw water, the process has been developed as a two -stage oxidant
to limit the addition of disassociated chloride from the chemical reagents used for treatment.
Finished water pH is estimated to be similar to the reported feed water pH. No pH conditioning
of the finished water is expected. However, if during the course of pilot testing results are contrary
to this preliminary assessment a pH dosing system will be included.
The unit processes will undergo periodic backwash and regeneration. The waste from these
processes is expected to be returned to the pit.
ONGOING WORK
The Design Basis Memorandum provides the framework for detailed design and Issued for
Construction Documents.

Pit Lake Profile Sampling Results

With the December 13, 2022 permit application, Albemarle included analytical data from water
quality sampling of the Pit Lake. As per NCDEQ's April 27, 2023 ADI letter, a one-time
sampling event for the pollutants not previously sampled on EPA's Form 2D tables A, B, C and
D has been included as this attachment to Form 2D. Samples were collected at various depths in
the Pit Lake to provide a complete profile of the water column.
On Form 2D, analytical results from samples taken at a depth of 150ft were entered into tables
A, B, C, and D. These results do not take into account any mixing or dilution that would occur
during withdrawal and are representative of only a small section of the total volume. Table 1
shows the percentage of Pit Lake Volume that each of the depths represent. The remainder and
majority of the discharge will have lesser values as you can see the following data summary
tables.

Attachment 4
EPA Form 2E Section 7

SECTION 7. OTHER INFORMATION (40 CFR 122.21(h)(7))
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 Engineering Alternative Analysis Attachment). The attached Kings Creek Stability and
Water Quality Assessment 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 affect 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 discharging to Kings Creek. The attached Plan Sets show the facility and proposed
aboveground pipeline will run from the pit to South Reservoir along existing roads with no additional
ground disturbance.
