NCG02 Application Supplemental Information
Introduction
The Carolina Lithium Project (Project) consists of the Concentrate Operations (mine operations) and the
Lithium Hydroxide Concentrate Plant (processing operations). The Concentrate Operations include the
Piedmont Lithium Carolinas Mine #1, a Concentrate Plant, and an Industrial Minerals Plant which make
up the mine operations. Marshall Miller & Associates (MMA) was the engineer of record for the
Concentrate Operations and HDR Engineering Inc. of the Carolinas (HDR) was the engineer of record for
the Lithium Hydroxide Conversion Plant. Piedmont Lithium Carolinas, Inc (PLCI), the applicant, proposes
to mine pegmatite ores which include spodumene for the purpose of lithium extraction, as well as quartz,
mica (muscovite), feldspar (albite and microcline), other mineral products, and rock products including for
aggregate and other industrial or construction purposes on 1,548 acres located about 1 mile east of
Cherryville, NC off/near road St. Marks Church Road, Whitesides Road, and Hephzibah Church Road in
Gaston County (Appendix A, Figures 7 and 2). A figure depicting land parcels with the Project boundary
is included as Figure 3 (Appendix A). A copy of PLCI's most recent Annual Report to the NC Secretary
of State is included as Appendix B.
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 30, 2021. At the date of this application for the NCG02 Notice of Intent, the review
process for the mine permit is currently ongoing. DEMLR is conducting a Public Hearing on November 15,
2021 as part of the mine permit review process.
Conversion Operation pit discharge will be collected in pit discharge ponds shown on the mine map
prior to being released (Appendix A, Figure 4, and Appendix C). Lithium Hydroxide Conversion
Plant construction stormwater will be collected in sediment basins and sediment traps shown on the
mine map prior to being released (Appendix A, Figure 4, and Appendix D). Water from these sediment
and erosion control measures, or the pits, will be discharged at a non -erosive rate back to surface waters
or will be used as makeup water for the Concentrate Plant.
See Appendix E for line drawing and pictorial description of water flow through the facility
USACE Wetland Delineation
A wetland delineation was performed in June 2018, December 2018, and in April 2019. The United States
Army Corps of Engineers issued a Jurisdictional Determination on February 21, 2019 and again on June
20, 2019, for the areas delineated at that time. The areas within the mine boundary that have not been
verified have been delineated and are currently under review by the USACE (Appendix A, Figure 5 and
Appendix F).
Pump Dewatering Size and Dewatering Method Details
The proposed mine dewatering plan includes pumping water from pits during excavation. As each open
pit is developed, water encountered in the pit will be channeled to a low spot, or sump, within the
excavation. Water will be pumped from the sumps in the pit using pumps that are adequately sized to
control the water in the pit. The water from the pits will be pumped to pit discharge settling ponds outside
of the pit, from which water will be either pumped out for operational use or discharged to the creek. The
pit discharge ponds have been designed to provide adequate storage for expected pit dewatering
activities.
For pit dewatering activities, the potential size for dewatering pumps include vertical turbine, 8 stage 200
horsepower pumps 12CHC 8 stage 200 HP 3 phase 480 v 1770 rpm 1000 gpm max; however, variation
in pump size may occur due to actual conditions. For pit dewatering activities, water from the pits would
be discharged through sediment basins.
The operation for the proposed Project involves sequenced excavation and mining of four pits. Mining is
planned to begin in the South Pit, with excavation of the East Pit beginning as the South Pit is exhausted
The West Pit excavation will begin as mining in the East Pit is being completed, and mining in the North
Pit will begin shortly after West Pit mining commences. The West and North pits will be mined together
until the reserves are exhausted. Locations of pit discharge ponds for each pit are indicated in Appendix
C and Appendix D. All pits have one planned pit discharge pond, with the exception of West Pit which
has two pit discharge ponds to accommodate the location of a main access/conveyor road.
Mine dewatering operations include pumping water from pits during excavation. Pit water is expected to
be pumped concurrently from South Pit and East Pit during approximately the first five years of mining,
with pumping from South Pit ceasing around Year 5 and pumping from only East Pit occurring in
approximately Years 6 through 11. Pumping in Year 12 is expected to be from both East Pit and West Pit
and pumping in Year 13 is expected to be from both North Pit and West Pit. Pumping is expected to be
only from West Pit beginning around Year 14 and continuing for the remainder of the life of the mine.
The pit pumping sequence may vary throughout the life of the Project. As each open pit is developed,
water encountered in the pit will be channeled to a low spot, or sump, within the excavation. Pit water will
be pumped from the sumps using pumps that are adequately sized to control the water in the pit. The
water from the pits will be pumped to the pit discharge ponds, from which water will be either pumped out
for operational freshwater use or discharged via controlled release from permitted outfalls to local surface
water bodies.
Settling Pond Sizing Information
The pit discharge ponds have been sized to provide adequate storage for the potential combination of
maximum expected pit dewatering activities (-2,300 gallons per minute or gpm) and large storm events.
The pit discharge ponds are designed to store approximately 1,000,000 gallons of water from the pit area
as needed during operations. The pit discharge pond spillways are designed to discharge the 100-year,
24-hour storm event and maximum pit dewatering flow as determined by groundwater modeling. Pit
dewatering ponds are designed with a non -erodible riprap lined spillway to discharge water safely without
erosion.
Cone of Influence Calculations
There is no public water system in the vicinity of the mine locale. The estimated withdrawal rate range
across the life of the project (20 years) is 828,000 gpd — 3,312,000 gpd based on a groundwater modeling
report prepared by HDR in 2021 (Appendix G).
If mitigation for adversely impacted wells is necessary, PLCI may offer assistance to connect the affected
property to municipal water supply where municipal water service has been brought to a practical
distance to the affected property or, may offer to drill new, deeper residential water supply wells. PLCI is
also committed to installing observation wells located around the perimeter of the pit excavation areas to
monitor groundwater levels during mine operation (Appendix A, Sheet 1).
Description of Measures to Prevent Erosion and Flooding
Erosion and sediment control structures will be installed prior to disturbance in all areas of the operation.
Detailed designs for planned sediment basins, spillways, sediment traps, conveyance ditches and flumes
are included in the mine permit data package. Erosion and sediment control structures have been
designed to accommodate a 25-year, 24-hour storm event. All In -Stream Culverts are designed on a 100-
year, 24-hour storm event. Stormwater runoff will be captured and discharged from sediment basins in a
non -erosive manner as depicted and designed in the erosion and sedimentation control design.
Clean Water Act Section 404 and 401 Permits
In November 2019, PLCI received a Clean Water Act (CWA) Section 404 Standard Individual Permit from
the USACE. PLC[ has also received a Section 401 Individual Water Quality Certification from the North
Carolina Division of Water Resources (DWR). A copy of the approved Section 404 and Section 401
permits are included in Appendix H. The project as currently submitted in this Notice of Intent does not
propose impacts to streams and wetlands beyond those approved in the 2019 CWA Section 404/401
permits.
Pumping Operation and Monitoring Plan
A pumping operation and monitoring plan is included in Appendix I.
