Introduction
This NPDES application is for the Carolina Lithium— Lithium Hydroxide Conversion Plant which is owned
and will be operated by Piedmont Lithium Carolinas, Inc. (PLCI). This is a new facility, and as of the date
of this application, construction and subsequent operations have not commenced. A NPDES application
was submitted in December 2022 and this revised NPDES application is being submitted as a result of an
additional information request (ADI).
There are 13 outfalls treated in this application and include the following:
• Sediment Basins: SB-17 and SB 201-207
o SBs 201, 202, and 204 each have two outfalls per basin
• Skimmer Basins: SK-20 and SK-25
WAIVER REQUEST
The following waiver is requested herein this application in EPA Form 2D, Section 7.1 and 7.2 and Table
A.PLCI is hereby requesting monitoring and limit waivers for flow and temperature for all of the
aforementioned outfalls.
The monitoring and limit waivers are being requested for all outfalls because the application is for
stormwater-generated wastewater — no thermal inputs are proposed, and no process wastewater will be
discharged. Rain events that generate the stormwater runoff and seasonal temperature variations are
outside of PLCI's control.
CONCENTRATION OF POTENTIAL POLLUTANTS
There are no stormwater structures expected to receive stormwater with exposure to battery-grade lithium
hydroxide, Conversion Plant tailings, or crystallized salts.The basis of design for the sediment and skimmer
basins is erosion control and stormwater received in the basins will mainly be characterized as having
suspended sediment. However, based on the material being conveyed to the Lithium Hydroxide Conversion
Plant from the Lithium Mine/Concentrate Operations, a conservative prediction (e.g., worst case) of
potential constituents that may be discharged through the aforementioned basins is discussed below.
In Form 2D, Section 7 Tables B, C, and E, the provided concentrations of potential pollutants are based on
a Leaching Environmental Assessment Framework (LEAF) (EPA Method 1313) testwork campaign that
was performed, per request from Division of Energy, Mineral, and Land Resources (DEMLR), on material
proposed to be placed in the waste rock pile and used as backfill in the East and South pits (waste rock
material). LEAF is designed to evaluate leachability as a function of pH for inorganic, semi-volatile organic,
and non-volatile organic constituents in solid materials.
Seven material combinations were tested across seven pH scenarios. Of the seven material compositions
tested, the material composition sample relevant to this application is the material that combines native
potentially acid generating (PAG) material (i.e., native overburden that is not processed) and the Lithium
Mine/Concentrate Operations concentrator tailings, collectively called waste rock material— PLCI believes
this to be the "worst case" material condition based on laboratory results and is not necessarily indicative
of rain-touched materials across the Lithium Hydroxide Conversion Plant site; however, using this material
composition would conservatively cover potential discharges.The PAG/concentrator tailings material is one
combination of the waste rock material that will be placed in the waste rock pile and used as backfill in the
East and South pits at the Lithium Mine/Concentrate Operations facility (i.e., there are no waste rock piles
or pits at the Lithium Hydroxide Conversion Plant facility).

FN
The sample material was tested across seven pH LEAF tests. The applicable pH LEAF test for this
application is the Natural LEAF test. The Natural LEAF test was conducted using deionized water with extra
filtering at an approximate pH of 5.5. This Natural test is considered to be the best representation of
rainwater as present-day rain pH is usually below 5.7.'
Thus, because the NPDES application is for stormwater-generated wastewater(discharges resulting from
rain falling on materials at the Lithium Hydroxide Conversion Plant), the data presented in the NPDES
application are based on the results of leaching the Natural fluid (—pH 5.5)through material using the LEAF
method —to representatively demonstrate rain falling and leaching through materials that will ultimately be
discharged to surface waters.
MASS OF POTENTIAL POLLUTANTS
In Form 2D, Section 7 Tables B, C, and E, the mass of constituents has been updated to be reported in
Ibs/d. Using constituent concentrations from the data described above, the potential mass of each
constituent was calculated for each sediment and skimmer basin outfall using the respective basins'
skimmer drawdown rates (Qd) as the skimmers provide a controlled rate of discharge flow. Note that SIB
201, SB-202, and SB-204 each have two outfalls per basin.

dredged or fill material in waters of the United States done by their contractors.
11 .Special condition 11:
1) During the clearing phase of the project, heavy equipment shall not be operated in
surface waters or stream channels. Temporary stream crossings will be used to
access the opposite sides of stream channels. All temporary diversion channels and
stream crossings will be constructed of non-erodible materials. Grubbing of riparian
vegetation will not occur until immediately before construction begins on a given
segment of stream channel.
2) No fill or excavation impacts for the purposes of sedimentation and erosion
control shall occur within jurisdictional waters, including wetlands, unless the impacts
are included on the plan drawings and specifically authorized by this permit. This
includes, but is not limited to, sediment control fences and other barriers intended to
catch sediment losses.
3) The Permittee shall remove all sediment and erosion control measures placed in
waters and/or wetlands, and shall restore natural grades on those areas, prior to
project completion.
4) The Permittee shall use appropriate sediment and erosion control practices which
equal or exceed those outlined in the most recent version of the "North Carolina
Sediment and Erosion Control Planning and Design Manual" to ensure compliance

practices shall be in full compliance with all specifications governing the proper
design, installation and operation and maintenance of such Best Management
Practices in order to ensure compliance with the appropriate turbidity water quality
standards. This shall include, but is not limited to, the immediate installation of silt
fencing or similar appropriate devices around all areas subject to soil disturbance or
the movement of earthen fill, and the immediate stabilization of all disturbed areas.
Additionally, the project shall remain in full compliance with all aspects of the
Sedimentation Pollution Control Act of 1973 (North Carolina General Statutes
Chapter 113A Article 4). Adequate sedimentation and erosion control measures
shall be implemented prior to any ground disturbing activities to minimize impacts to
downstream aquatic resources. These measures shall be inspected and maintained

regularly, especially following rainfall events. All fill material shall be adequately
stabilized at the earliest practicable date to prevent sediment from entering into
adjacent waters or wetlands.
Rationale: This condition documents the permittees responsbility to employ
appropriate sediment and erosion control practices to avoid potential indirect impacts to
jurisdicitonal waters.

provided in accordance with the provisions outlined on the most recent version of the
attached Compensatory Mitigation Responsibility Transfer Form. The requirements
of this form, including any special conditions listed on this form, are hereby
incorporated as special conditions of this permit
Rationale: This permit condition was added to document compensatory mitigation
requirements for the project, to ensure compliance with the 404(b)(1) guidelines, and to
ensure that project impacts were not more than minimal.
16 No activity may substantially disrupt the necessary life cycle movements of those
species of aquatic life indigenous to the waterbody, including those species that
normally migrate through the area. All discharges of dredged or fill material within
waters of the United States shall be designed and constructed to maintain low flows
to sustain the movement of aquatic species.
4

Rationale: This condition addresses potential issues associated with the installation of
improperly designed and/or installed culverts.
17. Special Condition 17
1) Unless otherwise requested in the application and depicted on the approved
permit plans, culverts greater than 48 inches in diameter shall be buried at least one
foot below the bed of the stream. Culverts 48 inches in diameter and less shall be
buried or placed on the stream bed as practicable and appropriate to maintain
aquatic passage, and every effort shall be made to maintain existing channel slope.
The bottom of the culvert shall be placed at a depth below the natural stream bottom
to provide for passage during drought or low flow conditions. Culverts shall be
designed and constructed in a manner that minimizes destabilization and head
cutting.
2) Measures shall be included in the culvert construction/installation that will promote
the safe passage of fish and other aquatic organisms. The dimension, pattern, and
profile of the stream above and below a culvert or pipe shall not be modified by
widening the stream channel or by reducing the depth of the stream in connection
with the construction activity. The width, height, and gradient of a proposed opening
shall be such as to pass the average historical low flow and spring flow without
adversely altering flow velocity. Spring flow should be determined from gauge data,
if available. In the absence of such data, bankfull flow can be used as a comparable
level.
3) The Permittee shall implement all reasonable and practicable measures to ensure
that equipment, structures, fill pads, work, and operations associated with this
project do not adversely affect upstream and/or downstream reaches. Adverse
effects include, but are not limited to, channel instability, flooding, and/or stream
bank erosion. The Permittee shall routinely monitor for these effects, cease all work
when detected, take initial corrective measures to correct actively eroding areas, and
notify this office immediately. Permanent corrective measures may require additional
authorization by the U.S. Army Corps of Engineers.
Rationale: This condition documents the permittee's responsibility as it relates to the
installation of culverts.
18. If previously undiscovered cultural resources are encountered while condcuting
grading within the project area, the Corps shall be immediately notified in writing and
by telephone at: 828-271-7980 within 24 hours of the Permittee's discovery of the
resources so that coordination can be initiated with the Cherokee Nation and North
Carolina State Historic Preservation Office.
Rationale: This is to address the Cherokee Nations concern regarding the potential for
the discovery of cultural resources during the grading operations.

14. All work in or adjacent to streams shall be conducted so that the flowing stream does not come in
contact with the disturbed area. Approved best management practices from the most current version
of the NC Sediment and Erosion Control Manual,or the NC DOT Construction and Maintenance
Activities Manual, such as sandbags, rock berms, cofferdams, and other diversion structures shall be
used to minimize excavation in flowing water. [15A NCAC 02H .0506(b)(3) and (c)(3))
15. Culverts shall be designed and installed in such a manner that the original stream profiles are not
altered and allow for aquatic life movement during low flows. The dimension, pattern, and profile of
the stream above and below a pipe or culvert shall not be modified by widening the stream channel or
by reducing the depth of the stream in connection with the construction activity. The width, height,
and gradient of a proposed culvert shall be such as to pass the average historical low flow and spring
flow without adversely altering flow velocity. [15A NCAC 02H .0S06(b)(2) and (c)(2)).
Placement of culverts and other structures in streams shall be below the elevation of the streambed
by one foot for all culverts with a diameter greater than 48 inches, and 20%of the culvert diameter
for culverts having a diameter less than or equal to 48 inches,to allow low flow passage of water and
aquatic life.
If multiple pipes or barrels are required, they shall be designed to mimic the existing stream cross
section as closely as possible including pipes or barrels at flood plain elevation and/or sills where
appropriate. Widening the stream channel shall be avoided.
If bedrock is discovered during construction, then DWR shall be notified by phone or email within 24
hours of discovery.
Installation of culverts in wetlands shall ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions. When roadways, causeways, or other fill
projects are constructed across FEMA-designated floodways or wetlands, openings such as culverts
or bridges shall be provided to maintain the natural hydrology of the system as well as prevent
constriction of the floodway that may result in destabilization of streams or wetlands.
The establishment of native woody vegetation and other soft stream bank stabilization techniques
shall be used where practicable instead of rip-rap or other bank hardening methods.
16. Application of fertilizer to establish planted/seeded vegetation within disturbed riparian areas and/or
wetlands shall be conducted at agronomic rates and shall comply with all other Federal, State and
Local regulations. Fertilizer application shall be accomplished in a manner that minimizes the risk of
contact between the fertilizer and surface waters. [15A NCAC 02B .0200 and 15A NCAC 02B .02311
17. If concrete is used during construction,then all necessary measures shall be taken to prevent direct
contact between uncured or curing concrete and waters of the state. Water that inadvertently
contacts uncured concrete shall not be discharged to waters of the state. [15A NCAC 02B .02001

18. No temporary impacts are allowed beyond those included in this Certification. All temporary fill and
culverts shall be removed,and the impacted area shall be returned to natural conditions within 60
calendar days after the temporary impact is no longer necessary. The impacted areas shall be
restored to original grade, including each stream's original cross-sectional dimensions, planform
pattern, and longitudinal bed profile. All temporarily impacted sites shall be restored and stabilized
with native vegetation. [15A NCAC 02H .0506(b)(2) and (c)(2)]
19. All proposed and approved temporary pipes/culverts/rip-rap pads etc. in streams shall be installed as
outlined in the most recent edition of the North Carolina Sediment and Erosion Control Planning and
Design Manual or the North Carolina Surface Mining Manual or the North Carolina Department of
Transportation Best Management Practices for Construction and Maintenance Activities so as not to
restrict stream flow or cause dis-equilibrium during use of this Certification. [15A NCAC 02H
.0506(b)(2) and (c)(2)]
20. Any riprap required for proper culvert placement, stream stabilization, or restoration of temporarily
disturbed areas shall be restricted to the area directly impacted by the approved construction activity.
All riprap shall be buried and/or"keyed in" such that the original stream elevation and streambank
contours are restored and maintained, Placement of riprap or other approved materials shall not
result in de-stabilization of the stream bed or banks upstream or downstream of the area. [15A NCAC
02H .0506(b)(2)]
21. This Certification does not relieve the applicant of the responsibility to obtain all other required
Federal, State, or Local approvals before proceeding with the project, including those required by, but
not limited to Sediment and Erosion Control, Non-Discharge, Water Supply Watershed, and Trout
Buffer regulations.
22. All mechanized equipment operated near surface waters shall be inspected and maintained regularly

Justification:A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. In determining that the proposed activity will
comply with state water quality standards(including designated uses, numeric criteria, narrative
criteria and the state's antidegradation policy), the project must provide for replacement of
existing uses through compensatory mitigation.
2. Streams within the project limits that have been avoided by direct impacts from the project shall
be monitored for surface flow by the Permittee to establish any loss of hydrologic function/flow
and to determine if the streams continue to provide aquatic life propagation and biological
integrity per required in North Carolina Administrative Code 15A NCAC 2B .0211(1). Continuous
flow measurement shall occur through gauges installed at the locations identified as 401-1
through 401-8 as shown on the attached Monitoring Location Map.
Background flow measurements shall be conducted for a minimum of 1 year prior to the
commencement of pit dewatering activities and shall continue until a it can be demonstrated
that all possible pit dewatering conditions have been realized for a sufficient period of time to
document flow trends during each season, and any hydrologic function/flow impacts have been
sufficiently monitored. Annual reports of monitoring shall be submitted to the Winston-Salem
Regional Office on June 1 of each year.
If monitoring of stream flow indicates a reduction of flow of greater than 10% at any sampling
location,then the Permittee shall submit a report to the Division which includes an analysis of
of hydrologic and aquatic function of the stream. If the Division determines that there has been
a loss of functioning accordance with 15A NCAC 2B .0211(1)the Permittee shall submit a
mitigation plan to the Division.

Lithium Hydroxide Conversion Plant NPDES Permit Application i Engineering Alternatives Analysis L��
Purpose and Need r
1 Purpose and Need
HDR Engineering, Inc. of the Carolinas (HDR) was retained by Piedmont Lithium Carolinas, Inc.
(PLCI) to prepare an Engineering Alternatives Analysis (EAA) for management of stormwater
generated from operations of the proposed Carolina Lithium Project (Project) located near
Cherryville, NC. The Project is a fully integrated lithium hydroxide operation that will include a
proposed mine, spodumene concentrator, and lithium hydroxide conversion plant. An EAA is
required with any National Pollutant Discharge Elimination System (NPDES) application for a
new or expanding wastewater discharge, in accordance with 15A North Carolina Administrative
Code (NCAC) 2H.0105(c)(2). An Environmental Assessment (EA) was prepared for the Clean
Water Act Section 404/401 permitting process. Section 404 and 401 individual permit approvals
are included in Appendix A.
2 Project Description
PLCI proposes to mine pegmatite ores which include spodumene for the purpose of lithium
extraction, as well as quartz, mica (muscovite), feldspar (albite and microcline). The Project
comprises 1,548 acres and is located in an unincorporated area of Gaston County on private
land surrounding portions of Hephzibah Church Road, Whitesides Road, and St. Mark's Church
Road, approximately one mile east of Cherryville, North Carolina. The project site vicinity is
located within the Lincolnton West and Bessemer City 24K U.S. Geological Survey (USGS)
topographic quadrangles in Gaston County, North Carolina.
The Project consists of the Mine/Concentrate Operations and Lithium Hydroxide Conversion
Plant (processing operations).
HDR Engineering Inc. of the Carolinas (HDR) is the engineer of record for the Lithium
Hydroxide Conversion Plant which includes site layout, grading, stormwater, and erosion
control plans. The site layout includes an entrance road, rail access, rail storage, the
plant and associated administrative, operations, and maintenance buildings. The
adjacent proposed Carolina Lithium Mine/Concentrate Operations is not included in the
Project as described herein. A separate EAA has been prepared for the
Mine/Concentrate Operations.
The Mine/Concentrate Operations include the Piedmont Lithium Carolinas Mine, a
Concentrate Plant, Waste Rock Disposal Area, Topsoil Storage Pile, magazine location,
material conveyors, and haul/access roads, which make up the mine operations.
Marshall Miller &Associates (MMA) is the engineer of record for the Mine/Concentrate
Operations.
An application for a North Carolina Mining Permit was submitted to the North Carolina
Department of Environmental Quality (NCDEQ) Division of Energy, Mineral and Land
Resources (DEMLR) Mining Program on August 31, 2021. The mining permit included both the
Mine/Concentrate Operations and the Lithium Hydroxide Conversation Plant within the mine
boundary, which was approved May 2024 (Appendix A).

Design Flows and Wastewater Characteristics r
This EAA is specific to the management of operational stormwater generated at the Lithium
Hydroxide Conversion Plant (processing operations) described above.
3 Design Flows and Wastewater Characteristics
The proposed NPDES discharge to surface waters will consist of operational stormwater
collected from the areas of the Lithium Hydroxide Conversion Plant (processing operations).
Stormwater will be discharged to Beaverdam Creek and associated unnamed tributaries. Each
source is further described below along with estimated stormwater volumes and characteristics.
A Water Flow Diagram showing proposed NPDES outfalls and stormwater flows is included in
Appendix B.
3.1 Stormwater
This NPDES application and associated EAA is related to the collection, treatment, and
discharge of stormwater runoff from the Lithium Hydroxide Conversion Plant.
A system of sediment basins (SB-201 to SB-207) will be constructed for collecting stormwater
runoff from the Lithium Hydroxide Conversion Plant. These basins are located based upon site
topography to receive runoff from the various operations of the Lithium Hydroxide Conversion
Plant site.
Sediment basin SIB-1 7 and skimmer basins SK-20 and SK-25 will be constructed for collecting
stormwater runoff from an access road and the emulsion storage (i.e., blasting materials) and
truck parking area.
3.2 Stormwater Characteristics
The spodumene concentrate (from the adjacent mine) processed at the Lithium Hydroxide
Conversion Plant will be conveyed to the processing operations in an enclosed conveyor
system and will not be exposed to precipitation. Once received at the Lithium Hydroxide
Conversion Plant, the spodumene concentrate will be completely enclosed and protected from
precipitation prior to processing. There are no sediment or skimmer basins expected to receive
stormwater with exposure to spodumene concentrate.
The process wastewater effluent generated by the manufacturing operations to convert the
spodumene concentrate to lithium hydroxide will be pre-treated at an onsite pretreatment facility
and discharged to an offsite Publicly Owned Treatment Works (POTW) facility via the sewer
collection system. There are no sediment basins or skimmer basins that will receive this process
wastewater effluent.
The conversion plant product (lithium hydroxide) and solid waste streams (tailings and
crystallized salts) produced during the process have limited moisture and will be transported
offsite such that any leachate generated would be nominal and contained appropriately. No
discharge of process wastewater to the ground or surface waters would occur. The following
details the management of the Lithium Hydroxide Conversion Plant product and solid waste
streams:
2

Lithium Hydroxide Conversion Plant NPDES Permit Application I Engineering Alternatives Analysis L��
Design Flows and Wastewater Characteristics r
• Battery-grade lithium hydroxide product
o Transported offsite and sold to battery manufacturer.
o Does not have measurable moisture content.
o When stored at the plant prior to transportation, is stored in a completely
enclosed structure.
• Conversion Plant tailings and crystallized salts
o Transported to an offsite permitted facility.
o Has limited moisture content.
o When stored at the plant prior to transportation, is stored in a completely
enclosed structure (i.e., no exposure to rainwater) with designed containment
that ultimately routes to an onsite water pretreatment facility via a sump
system. The pretreated water would ultimately be discharged to an offsite
POTW.
There are no stormwater structures expected to receive stormwater with exposure to battery-
grade lithium hydroxide, Conversion Plant tailings or crystallized salts. The basis of design for
the sediment basins and skimmer basins is erosion control and stormwater received in the
sediment basins will mainly be characterized as having suspended sediment. However, based
on the material being conveyed to the Lithium Hydroxide Conversion Plant from the
Mine/Concentrate Operations, a conservative prediction (e.g., worse case) of constituents that
may be discharged through stormwater outfalls is shown below in Table 3.1 for SB-17, SB-201
— SB-207, SK-20, and SK-25.

Evaluation of Alternatives r
4 Evaluation of Alternatives
Five alternatives were evaluated for the management of operational stormwater for the Lithium
Hydroxide Conversation Plant:
• No Action;
• Alternative 2 — Connection to an Existing Wastewater Treatment Plant;
• Alternative 3 — Land Application;
• Alternative 4 —Wastewater Reuse; and,
• Alternative 5 — Discharge through the NPDES Program (Preferred Alternative).
4.1 No Action
The Project is a new lithium hydroxide operation being developed that is expected to produce
30,000 metric tons of lithium hydroxide per year when fully operational. The No Action
alternative is not considered feasible because it would prevent development of the Lithium
Hydroxide Conversion Plant. In this case, the spodumene concentrate (from the adjacent
mine/concentrate operations) would have to be shipped offsite for conversion into lithium
hydroxide.
4.2 Alternative 2: Connection to An Existing Wastewater
Treatment Plant
PLCI is proposing to pretreat the industrial process wastewater generated from the conversion
operations that convert concentrated spodumene to battery-grade lithium hydroxide. The
projected peak flow for this industrial process wastewater from the conversion plant is 0.39
million gallons per day (MGD) (270.83 gallons per minute [gpm]). This pretreated process
wastewater will be combined with sanitary wastewater at the site boundary for a proposed
discharge to a municipal wastewater treatment plant (WWTP).
As stated in Section 3 above, the proposed NPDES discharge to surface waters will consist of
stormwater collected from the areas of the Lithium Hydroxide Conversion Plant operations. For
Alternative 2, consideration is given to conveying peak stormwater flows from these operations
to another WWTP for treatment and discharge. Figure 4.1, below, shows municipal WWTPs that
have the potential to receive stormwater from the operation of the Piedmont Carolina project.
These include: 1) The City of Cherryville's Cherryville WWTP; 2) The City of Gastonia's Long
Creek WWTP; 3) The City of Shelby's First Broad River WWTP; and 4) The City of Lincolnton's
Lincolnton WWTP.

The peak design flows for the sediment and skimmer basins were determined by HDR (see
Section 4.5.1 for additional design criteria). The sediment and skimmer basins peak design
flows are based on runoff from the 25-year, 24-hour storm event (Table 4.2).

SB-17 30.22 20
Total Peak Flow: 262.56 171
Considering the sediment and skimmer basins above, the peak design flow is greater than the
combined available treatment capacity of all wastewater treatment facilities identified in Table
4.1.
In addition to considering the peak design flows from the Lithium Hydroxide Conversion Plant
site, municipal wastewater treatment facilities consist of a biological process in which active
microorganisms naturally breakdown organic matter by biological metabolism. The organic
composition is a principal characteristic of influent wastewater received at municipal treatment
facilities and is thus one of the main parameters used in the design of these treatment facilities.
Stormwater runoff from the Lithium Hydroxide Conversion Plant will have a very low organic
content verses the typical composition of untreated domestic wastewater. Additionally,
stormwater flows will be intermittent (based on the storm event), and when discharging, could
result in a surge in flow rate and sudden changes in the organic concentration entering the
municipal WWTP. The constantly changing amount and strength of wastewater to be treated
would make it difficult to operate the treatment processes efficiently.
Based upon the Lithium Hydroxide Conversion Plant stormwater runoff design flows and
expected stormwater characteristics, Alternative 2, connection to an existing WWTP, is not
considered a viable alternative due to insufficient treatment capacity and the potential for
creating ongoing operational difficulties at the receiving WWTP. Therefore, a present value cost
estimate is not provided.
4.3 Alternative 3: Land Application
The evaluation of land application of the stormwater system is based on 15A NCAC 02T.0500
and other applicable rules. This alternative would not allow any discharge since the land
application permit is not a federal NPDES permit. This presents a significant challenge for areas
in North Carolina where precipitation can be heavy over the entire year as well as seasonally
high. This would be particularly true for a system where the volume of effluent to be irrigated is
6

Lithium Hydroxide Conversion Plant NPDES Permit Application I Engineering Alternatives Analysis 1 ��
Evaluation of Alternatives r
directly proportional to the amount of rainfall (i.e., more rainfall means more effluent to be
sprayed), but irrigation is limited during those wetter timeframes.
A land application alternative would include the construction of collection and pumping
infrastructure, storage ponds, and irrigation facilities at dedicated land application sites, which
would likely be in multiple areas as large, contiguous tracts of suitable land may not be
available. These additional facilities would substantially increase the construction impacts
associated with this alternative.
To evaluate this alternative, nearby spray systems were examined for loading rates and
similarity in soils compared to areas surrounding the PLCI property. The volume of water that
must be disposed under the land application alternative was based on runoff estimates from
various areas of the mining operation.
The following nearby spray systems were reviewed as part of the land application alternative:
WQ0002052, Milliken & Company, Golden Valley Plant
This spray system consists of a 31,000 gpd wastewater treatment facility including a
1.36-million-gallon storage lagoon and 12.25 acres of spray fields. The approved loading
rate for irrigation is 57.2 inches per year on Pacolet soils (USDA Web Soil Survey).
WQ0003924, Linco Partnership, Lincolnton WWTF
This spray system consists of a 60,000 gpd wastewater treatment facility including a
300,000-storage tank, 2.0-million-gallon storage lagoon and 21.5 acres of spray fields.
The approved loading rate for irrigation is 45.5 inches per year on Pacolet, Altavista, and
Lloyd soils (WQ0003924). This land application system has failed based on the Notice of
Continuing Violation and Notice of Intent to Enforce (issued April 13, 2021) from the
North Carolina Department of Environmental Quality.
WQ0004270, AB Carter, Gastonia WWTP
This spray system consists of a 5,000 gpd wastewater treatment facility including a
235,000-gallon storage lagoon and two acres of spray fields. The approved loading rate
for irrigation is 26 inches per year on Cecil soils (WQ0004270).
Based on Natural Resources Conservation Service Soil Survey information, the soils
surrounding the Project primarily include Cecil, Lloyd, Madison, and Pacolet soils which are
similar to the soils in the three nearby spray systems. These soils are generally well drained, on
typical piedmont topography. However, for this analysis a detailed soils report was not obtained
since it is understood that design loading rates are not needed at this time. For the three
permitted spray systems permitted in the region, annual loading rates vary significantly from 26
inches per year to 57 inches per year. The loading rate for WQ0003924 was +/-45 inches per
year; however, that system has failed. The mechanism for failure (e.g., soils improperly
classified, lack of maintenance, groundwater mounding, etc.) is not known. For the purposes of
this alternative, the average of two of the three systems (WQ0002052, WQ0004270) was used
(i.e., 42 in/yr) as an estimated average loading rate. This is not significantly different than using
7

Lithium Hydroxide Conversion Plant NPDES Permit Application I Engineering Alternatives Analysis 1 ��
Evaluation of Alternatives r
the average of three systems since the failed system's (WQ0003924) loading rate (45 in/yr) is
very to close the assumed average loading rate.
A detailed water balance was not performed; however, typical storage volumes were used from
the three nearby spray systems detailed above. The average days of storage for these three
systems was 43 days of storage. The assumed value for evaluating this alternative was 45
days. A slightly higher value was used than the average since WQ0003924 (failed system) had
only 38 days storage while the others were 47 and 44 days.
Based on the loading rates and assumed wetted/total acreage ratio, the total land needed for
irrigation fields was estimated. The wetted acreage for a spray system is much less than actual
total land needed since property lines, streams, drainage ways, excessive slopes, etc. must be
buffered. In addition, the irregular shape of many piedmont fields based on topography also
create pockets that are not practical to irrigate with the large irrigation spray heads (typical
radius is 90-100 ft.) needed for this type of irrigation system. There may also be small inclusions
of poorer soils that should not be irrigated within a larger field. For this evaluation, it was
assumed that the ratio of total to wetted acres was 1.6 for a given parcel that theoretically could
be available for utilization for spray irrigation (i.e., wetted area). That is, for every irrigatable
acre, 1.6 acres would need to be obtained. This ratio was based on the examination of two large
irrigation areas near the proposed mine.
Based on the assumed loading rate of 42 in/yr, a total of 66 wetted acres are needed for spray
irrigation. Based on the total/wetted ratio of 1.6, a total of 106 acres is needed to be purchased
for the system. For larger tracts of land in the area surrounding the Project, the market rate per
acre is approximately $3,800/acre based on market rate determinations from the Gaston County
Tax Office.
For this alternative, it is assumed a pump station is located at the location of proposed outfalls
and all stormwater is pumped to a central location for storage prior to irrigation. The pump
stations would have common force mains as flow is collected across the site. Based on eight
operational sediment basins and two operational skimmer basins, there would be a total of 10
pump stations. The length of force main was estimated based on the distance from between
each pump station and then to an assumed central location where the storage pond could be
located. The assumed location for a storage pond was on the northeast side of Hephzibah
Church Road near the intersection of Whitesides Road.
The overall cost of constructing is $73,327,803 with additional details provided in Table 4.3. This
alternative is rejected based on the overall costs of this alternative.

4.4 Alternative 4: Wastewater Reuse
Under North Carolina regulations, 15A NCAC 02U, reclaimed water can be used for non-
potable purposes including:
9

Lithium Hydroxide Conversion Plant NPDES Permit Application I Engineering Alternatives Analysis L��
Evaluation of Alternatives r
• Irrigation of public and private landscapes and turf
• Soil compaction
• Dust control
• Non-potable processes such as concrete production and cooling water
• Industrial and commercial toilet flush and fire prevention systems where there are
separate, non-potable plumbing lines
• Decorative ponds and fountains
• Street sweeping (not street cleaning)
• Sewer cleaning (not washing)
• Vehicle washing
There are no additional reuse alternatives for stormwater from the Lithium Hydroxide
Conversion Plant area.
The proposed Project site is located in a rural area in northwest Gaston County, near the city of
Cherryville. Based upon available information from the Division of Water Resources Document
Repository, the City of Cherryville does not have any current Significant Industrial Users (SIUs).
As such, there are no industries in close proximity to the Project site that would be candidates
for water reuse opportunities.
There are no viable reuse opportunities for the Lithium Hydroxide Conversion Plant that would
reduce the NPDES discharge volume. Wastewater reuse therefore is not considered a viable
alternative at this time and a cost estimate is not provided.
4.5 Alternative 5: Discharge through the NPDES Program
Discharge of stormwater water via an NPDES permit is the preferred alternative based on the
evaluation of other alternatives.
As discussed in Alternative 2, conveying stormwater from Lithium Hydroxide Conversion Plant
to a municipal wastewater treatment plant (WWTP) is not a viable option, because these
WWTPs are specifically designed to biologically treat wastewater that has an organic
composition. Whereas stormwater from the Lithium Hydroxide Conversion Plant would be much
more dilute and characterized as having a low organic composition. Generally, municipal
wastewater collection facilities are designed to exclude stormwater and groundwater. None of
the nearby municipal systems are designed to be combined (sanitary and storm) sewers.
Additionally, municipalities are investing in capital projects to reduce and attenuate stormwater
inflows to the sewer collection and treatment system.
Land application, as evaluated in Alternative 3, would require approximately 106 additional
acres that PLCI would need to acquire for the Project. Additionally, this alternative would require
the construction of a storage basin, associated pump stations, force mains, and the irrigation
system. Thus, notwithstanding additional acreage needed, this alternative is cost prohibitive.
Additionally, there are no viable reuse opportunities that would eliminate the need for a NPDES
permitted discharge.
10

Lithium Hydroxide Conversion Plant NPDES Permit Application I Engineering Alternatives Analysis L��
Evaluation of Alternatives r
Therefore, a discharge through the NPDES program is the most viable option for managing
stormwater from the operations of the Lithium Hydroxide Conversion Plant.
4.5.1 New Infrastructure
Operational stormwater from the Lithium Hydroxide Conversion Plant will be managed through a
series of sediment and skimmer Basins. The location of these structures is based upon site
topography and will intercept water from the project site for discharge to the receiving streams.
Each basin outlet is assigned an NPDES Outfall number.
The design criteria for the sediment and skimmer basins are as follows:
• Sediment Basins (SB-17 and SB-201 — SB-207):
o Design Storm: 25-year, 24-hours.
o Maximum Drainage Area: 100 acres per basin.
o Minimum Surface Area: 435 ft2/cfs or greater.
o Minimum Volume: 1,800 ft3/acre of disturbed area draining to basin.
o Dewatering Mechanism: Skimmer with orifice sized to achieve dewatering the
basin over a 3-day period; each sediment basin has a specific controlled
drawdown rate (Qd) based on the skimmer orifice sized to the respective basin;
discharge will occur through a principal outfall.
o Emergency spillway designed to discharge at the 25-year, 24-hour storm event.
• Skimmer Basins (SK-20 and SK-25):
o Design Storm: 25-year, 24-hours.
o Maximum Drainage Area: 10 acres per basin.
o Minimum Surface Area: 325 ft2/cfs or greater.
o Minimum Volume: 1,800 ft3/acre of disturbed area draining to basin.
o Dewatering Mechanism: Skimmer with orifice sized to achieve dewatering the
basin over a 2 to 3-day period; each skimmer basin has a specific controlled
drawdown rate (Qd) based on the skimmer orifice sized to the respective basin;
discharge will occur through a principal outfall.

Rationale: This condition addresses potential issues associated with the installation of
improperly designed and/or installed culverts.
17. Special Condition 17
1) Unless otherwise requested in the application and depicted on the approved
permit plans, culverts greater than 48 inches in diameter shall be buried at least one
foot below the bed of the stream. Culverts 48 inches in diameter and less shall be
buried or placed on the stream bed as practicable and appropriate to maintain
aquatic passage, and every effort shall be made to maintain existing channel slope.
The bottom of the culvert shall be placed at a depth below the natural stream bottom
to provide for passage during drought or low flow conditions. Culverts shall be
designed and constructed in a manner that minimizes destabilization and head
cutting.
2) Measures shall be included in the culvert construction/installation that will promote
the safe passage of fish and other aquatic organisms. The dimension, pattern, and
profile of the stream above and below a culvert or pipe shall not be modified by
widening the stream channel or by reducing the depth of the stream in connection
with the construction activity. The width, height, and gradient of a proposed opening
shall be such as to pass the average historical low flow and spring flow without
adversely altering flow velocity. Spring flow should be determined from gauge data,
if available. In the absence of such data, bankfull flow can be used as a comparable
level.
3) The Permittee shall implement all reasonable and practicable measures to ensure
that equipment, structures, fill pads, work, and operations associated with this
project do not adversely affect upstream and/or downstream reaches. Adverse
effects include, but are not limited to, channel instability, flooding, and/or stream
bank erosion. The Permittee shall routinely monitor for these effects, cease all work
when detected, take initial corrective measures to correct actively eroding areas, and
notify this office immediately. Permanent corrective measures may require additional
authorization by the U.S. Army Corps of Engineers.
Rationale: This condition documents the permittee's responsibility as it relates to the
installation of culverts.

grading within the project area, the Corps shall be immediately notified in writing and
by telephone at: 828-271-7980 within 24 hours of the Permittee's discovery of the

Justification:A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. In determining that the proposed activity will
comply with state water quality standards(including designated uses, numeric criteria, narrative
criteria and the state's antidegradation policy), the project must provide for replacement of
existing uses through compensatory mitigation.
2. Streams within the project limits that have been avoided by direct impacts from the project shall
be monitored for surface flow by the Permittee to establish any loss of hydrologic function/flow
and to determine if the streams continue to provide aquatic life propagation and biological
integrity per required in North Carolina Administrative Code 15A NCAC 2B .0211(1). Continuous
flow measurement shall occur through gauges installed at the locations identified as 401-1
through 401-8 as shown on the attached Monitoring Location Map.
Background flow measurements shall be conducted for a minimum of 1 year prior to the
commencement of pit dewatering activities and shall continue until a it can be demonstrated
that all possible pit dewatering conditions have been realized for a sufficient period of time to
document flow trends during each season, and any hydrologic function/flow impacts have been
sufficiently monitored. Annual reports of monitoring shall be submitted to the Winston-Salem
Regional Office on June 1 of each year.
If monitoring of stream flow indicates a reduction of flow of greater than 10% at any sampling
location,then the Permittee shall submit a report to the Division which includes an analysis of
of hydrologic and aquatic function of the stream. If the Division determines that there has been
a loss of functioning accordance with 15A NCAC 2B .0211(1)the Permittee shall submit a
mitigation plan to the Division.

Justification:Surface water quality standards require that conditions of waters be suitable for all
best uses provided for in state rule, and that activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. Ensuring that structures are installed
properly in waters will ensure that surface water quality standards are met and conditions of
waters are suitable for all best uses.
18. Any rip-rap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All rip-rap shall be placed such that the original streambed elevation and
streambank contours are restored and maintained and shall consist of clean rock or masonry
material free of debris or toxic pollutants. Placement of rip-rap or other approved materials
shall not result in de-stabilization of the stream bed or banks upstream or downstream of the
area or be installed in a manner that precludes aquatic life passage.

Justification:Surface water quality standards require that conditions of waters be suitable for all
best uses provided for in state rule, and that activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. The Division must evaluate if the
activity has avoided and minimized impacts to waters, would cause or contribute to a violation
of standards, or would result in secondary or cumulative impacts.
19. Any rip-rap used for stream or shoreline stabilization shall be of a size and density to prevent
movement by wave, current action, or stream flows, and shall consist of clean rock or masonry
material free of debris or toxic pollutants. Rip-rap shall not be installed in the streambed except
in specific areas required for velocity control and to ensure structural integrity of bank
stabilization measures.

precludes any best use on a short-term or long-term basis. The Division must evaluate if the
activity has avoided and minimized impacts to waters, would cause or contribute to a violation
of standards, or would result in secondary or cumulative impacts.
20. All mechanized equipment operated near surface waters shall be inspected and maintained
regularly to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids, or
other toxic materials. Construction shall be staged in order to minimize the exposure of
equipment to surface waters to the maximum extent practicable. Fueling, lubrication, and
general equipment maintenance shall be performed in a manner to prevent,to the maximum
extent practicable, contamination of surface waters by fuels and oils.

Justification:A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. Activities must not cause water pollution that
precludes any best use on a short-term or long-term basis.As cited in Stream Standards: (12)
Oils, deleterious substances, or colored or other wastes:only such amounts as shall not render
the waters injurious to public health, secondary recreation, or to aquatic life and wildlife, or
adversely affect the palatability offish, aesthetic quality, or impair the waters for any designated
uses.As cited in Wetland Standards: (c)(1)Liquids,fill or other solids, or dissolved gases shall not
be present in amounts that may cause adverse impacts on existing wetland uses;and(3)
Materials producing color or odor shall not be present in amounts that may cause adverse
impacts on existing wetland uses.
21. Heavy equipment working in wetlands shall be placed on mats or other measures shall be taken
to minimize soil disturbance and compaction.
Citation: 15A NCAC 02H.0506(b);15A NCAC 0214.0507(c); 15A NCAC 028.0231
Justification: Wetland standards require maintenance or enhancement of existing uses of
wetlands such that hydrologic conditions necessary to support natural biological and physical
characteristics are protected,populations of wetland flora and fauna are maintained to protect
biological integrity of the wetland;and materials or substances are not present in amounts that
may cause adverse impact on existing wetland uses.
22. In accordance with 143-215.85(b),the permittee shall report any petroleum spill of 25 gallons or
more; any spill regardless of amount that causes a sheen on surface waters; any petroleum spill
regardless of amount occurring within 100 feet of surface waters; and any petroleum spill less
than 25 gallons that cannot be cleaned up within 24 hours.
Citation: 15A NCAC 02H.0507(c);N.C.G.S 143-215.85(b)
Justification:Person(s)owning or having control over oil or other substances upon notice of
discharge must immediately notify the Department, or any of its agents or employees, of the
nature, location, and time of the discharge and of the measures which are being taken or are
proposed to be taken to contain and remove the discharge. This action is required in order to
contain or divert the substances to prevent entry into the surface waters. Surface water quality
standards require that conditions of waters be suitable for all best uses provided for in state rule
(including, at minimum:aquatic life propagation, survival, and maintenance of biological
integrity; wildlife;secondary contact recreation;agriculture), and that activities must not cause
water pollution that precludes any best use on a short-term or long-term basis.
23. The permittee and their authorized agents shall conduct all activities in a manner consistent
with State water quality standards (including any requirements resulting from compliance with
§303(d) of the Clean Water Act), and any other appropriate requirements of State and Federal
Law.
