DIRECTIONS TO THE SITE The Piedmont Lithium mine is centered around 1501 Hephzibah Church Road in Bessemer City, North Carolina (Figure 1, Appendix A). From US -321 N, take Exit 12B for NC -275 W/NC-279 W. Take a right onto NC -275 W, then continue onto NC -279 W for 7.3 miles. Take a right onto Hephzibah Church Road and continue to follow Hephzibah Church Road for 0.9 miles, then turn left to stay on Hephzibah Church Road for another 1.5 miles. Address above is the locality for the bridge crossing of Beaverdam Creek on Hephzibah Church Road, which is the approximate center of the site. On-site waters include Little Beaverdam Creek and Beaverdam Creek, which ultimately drain to the South Fork Catawba River. 18. Nature of Activity (Description of project, include all features) The proposed project would involve the development of a hard rock lithium mine, which includes the construction of an open pit, awaste rock area, a concentrator plant site, access roads, and applicable National Pollutant Discharge and Elimination System (NPDES) best management practices (BMPs). The project would result in impacts to 1,263 linear feet of perennial stream channel and 4,547.5 linear feet of intermittent stream channel (5,810.5 linear feet total), 0.14 acre of wetlands, and 0.16 acre of pond. Approximately 781 linear feet of perennial stream channel, 2,283 linear feet of intermittent stream channel, 0.14 acre of wetlands, and 0.16 acre of ponds will be impacted by waste rock areas. Approximately 249 linear feet of perennial stream channel and 2,264.5 of intermittent stream channel will be impacted by pit shell areas. Approximately 178 linear feet of perennial stream channel will be impacted by an internal access road stream crossing and 55 linear feet of perennial channel will be impacted by a stormwater BMP. Figure 3 (Appendix A) depicts the proposed site layout. (see supplemental document for additional information). 19. Project Purpose (Describe the reason or purpose of the project, see instructions) The global transition away from hydrocarbons toward energy alternatives has increased demand for many scarce metals. Among these is lithium (Li), a key component in lithium -ion batteries for electronic devices, particularly electric and hybrid vehicles, laptop computers, and cell phones. Forecasted growth in both global lithium demand and supply varies among analysts and industry experts; however, Roskill forecasts overall growth in lithium consumption to average 15.3% per year to 2027 (Roskill's Base -Case Scenario). Consumption of lithium will continue to be driven by the rechargeable battery sector, which is forecast to register 22.4% per year growth through to 2027. The global leaders in lithium supply are Australia, Chile, and Argentina at 37%, 36%, and 17%, respectively, while the U.S. supplies only 2% to the global market. And although there are untapped lithium reserves in the U.S., the U.S. imports two-thirds of the lithium needed to meet domestic demand. Expanding the lithium supply in the U.S. would ensure a domestic source and insulate domestic prices in a global market. Thus, a domestic lithium source is needed to supplement demands in the U.S. (see supplemental document) USE BLOCKS 20-23 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED 20. Reason(s) for Discharge There are multiple disposal sites (impacts) located throughout the project site. Impact 1 is the only stream crossing. Impacts 2-7 are those associated with pit construction. Impacts 8-16 are those associated with waste rock area construction. Figure 4 (Appendix A) depicts the impact site locations. With the exception of one impact (Impact 1), all other impacts are located on shallow, first order streams that originate on site. The impact sites would contain no flow or be dewatered prior to construction which would eliminate the stream velocities and prevent and control turbidity, stratification, and other factors typically associated with mixing soil with water. All fill material would be clean fill material originating from on site and readily available to the applicant. (see supplemental document for additional information) 21.

Other Location Descriptions There are 74 parcels associated with the proposed project. See the Tax Parcel ID Map (Figure 2, Appendix A) and the list of property ownership in Appendix B. Block 18. Nature of Activit The Piedmont Lithium mine would generate approximately 11.2 million cubic yards of lithium bearing spodumene ore and 83.2 million cubic yards of waste rock and tailings. The project proposes to extract lithium bearing spodumene from the open pit, which is within host rock in a geologic formation called a pegmatite dyke and would then be separated into ore, waste, and byproduct. The separation of lithium bearing spodumene ore and marketable byproducts from the host rock would be conducted at an on-site concentrator plant. The project boundary has been developed to encompass open pits, waste rock areas, appropriate NPDES BMPs, internal access roads, the concentrator unit, and all other necessary support facilities. Large waste rock areas would be required to accommodate as much as all pit waste as possible since offsite removal of waste rock is not practicable due to the volume of material that would be generated. The full 200 -acre open pit areas and 145 -acre waste rock areas are needed for the applicant to meet the project purpose. The construction sequence would first require the establishment of 300 foot mining buffers around the entire perimeter of the project site as required by Gaston County. The Federal Emergency Management Act (FEMA) 100 -year floodplain would also be maintained along the entirety of Beaverdam and Little Beaverdam Creeks. Next, the sediment and erosion control measures would be installed around the perimeter of the site to control stormwater flows. The North Carolina Mine Permit requires that all sediment and erosion control measures such as ditches, ponds, rock dams, be designed for the 25 -year storm. Underdrains would be placed in the waste rock areas to capture normal groundwater flows in areas where existing streams will be filled. Additional NPDES BMPs would be installed in appropriate areas to treat stormwater runoff of the site in general as needed. Clearing of the pit and waste area sites would occur before the open pit and waste rock area are constructed and only cleared as needed during the development of the pit and waste rock areas. Internal roads would be constructed for pit and waste rock area access throughout the mine site. The open pits will have design parameters similar to batter face angles of 80 degrees, a batter height of 40 feet (12.2 meters), a berm width of 20 feet (6.1 meters), an overall wall angle of 52 degrees, and a ramp width of 80 feet (24.8 meters) for transportation of material. The waste rock area would contain as much pit waste as possible since offsite removal of waste rock is not practicable due to the volume of material that would be generated. The majority of remaining waste will be returned to the pit as backfill once pit voids have been established. A percentage of waste will also be separated as marketable byproducts, such as mica and feldspar. Filter cake waste from the concentrator will also be placed in the waste rock area and co -disposed with waste rock. Page 11 ENG Form 4345 Supplemental Document Piedmont Lithium SAW -2018-01129 The Piedmont Lithium site was acquired by the applicant for the purpose of managing all the aforementioned mining activities in close proximity to one another. The proposed impacts would result from the construction of open pits, waste rock areas, and one access road crossing. There are multiple disposal sites (impacts) located throughout the project site. Impact 1 is the only stream crossing. This impact would consist of a culvert installation. Impacts 2-7 are those associated with pit construction. Impacts 8-16 are those associated with waste rock area construction. All impacts would be the result of discharge (fill) material consisting of clean fill material originating from on site and readily available to the applicant. The impact sites would contain no flow or be dewatered prior to construction which would eliminate the stream velocities and prevent and control turbidity, stratification, and other factors typically associated with mixing soil with water. Figure 4 depicts the impact site locations, which are described in detail in Blocks 20-22. Block 19. Project Purpose The main sources of lithium used in cathodes of lithium -ion batteries are spodumene (a mineral) and sub - saline brines. Lithium -ion batteries require lithium hydroxide (LiOH), which is expected to be the fastest growing product of the lithium market. Global Lithium, LLC projects sustained relatively firm lithium hydroxide pricing over the next five to seven years based on the consensus opinion of lithium producers, purchasers and industry experts that lithium demand to produce lithium hydroxide will grow a minimum of 300% between 2017 and 2025. To produce lithium hydroxide, lithium must be extracted from either hard rock sources such as spodumene or extracted through an evaporative process from sub -saline brines. Extracting spodumene- containing lithium is accomplished by utilizing traditional hard rock mining techniques of open pit drilling and separation of lithium from host rock using a series of physical and chemical processes to produce lithium concentrate. This process can be completed as fast as the material can be moved from an open pit to a concentrator plant. Saline -based projects rely upon pumping saline -containing lithium from underground reserves to the earth's surface, which is then pumped through a series of evaporation ponds, each having a higher concentration of lithium than the last. This process can take months to a year or more, depending on weather, to yield adequate lithium concentrate. Both spodumene- and saline - based projects require conversion of lithium concentrate through purification and crystallization into battery -grade quality lithium hydroxide of the type which can be used in cathodes for the manufacturing of electric car batteries. According to Roskill Industry Cost Curves, it is more cost efficient to produce battery -grade quality lithium hydroxide from lithium concentrates extracted from spodumene-based projects than with saline -based projects.' Lithium conversion with spodumene-based projects cost approximately $2,500 to $3,500 per metric tonne (1.1023 US tons) of lithium hydroxide produced while lithium conversion with saline -based projects cost approximately $4,500 to $6,500 per metric tonne of lithium hydroxide produced. Moreover, if lithium concentrates are shipped to China (a common practice in the industry) for this conversion/purification process (vs. on-site or nearby conversion locations), costs increase to approximately $7,500 to $9,500 per metric tonne of lithium hydroxide produced. Since spodumene-based lithium extraction projects are more cost efficient than saline -based lithium extraction projects to produce battery -grade lithium hydroxide and since there is a need for a domestic supply of lithium, spodumene reserves containing lithium located in the U.S. were considered for development. Spodumene based lithium reserves located outside the US were not considered Roskill Market Reports and Consultancy. 2018. Lithium Industry Cost Curves. https://roskill.com/roskill-Product/lithium-industry- cost-curves/ Page 12 ENG Form 4345 Supplemental Document Piedmont Lithium SAW -2018-01129 reasonable or practicable alternative to provide domestic sources of lithium. While there are a few lithium reserves contained in mineralized spodumene in the US, the largest lithium reserves are located within the Carolina Tin-Spodumene Belt (TSB), in North Carolina, according to the US Geological Survey (USG S).2 The Carolina TSB was the world's largest producer of lithium after World War II, from the 1950's through the 1980's and infrastructure such as rail and highway are still existing which can be utilized to access and support mining operations today .3 An attractive draw for potential investors and local labor forces, the Carolina TSB is also close (< 30 minutes) to multiple metropolitan areas, such as Gastonia and Charlotte. Therefore, the purpose of the project is to develop a hard rock lithium mine in the Carolina TSB, to extract and refine mineralized spodumene to a high quality lithium bearing spodumene concentrate; which, upon conversion to a battery grade lithium hydroxide, will provide a domestic source of lithium to meet growing demands in the U.S. Block 20. Reason(s) for Discharge Impact 1: Stream crossing The proposed reinforced concrete pipe (RCP) would be placed directly in 178 linear feet of jurisdictional Perennial Stream 2 (Figure 5, Appendix A). The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill material would also be free of toxic pollutants in toxic amounts. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that the substrate of remaining waters of the United States would not change or be affected. The pipe will be buried 1 foot if larger than 48 inches in diameter or will be buried 20% of the diameter if less than 48 inches, so as not to impede low flows and aquatic life movement. Impacts 2 — 7: Those associated with pit construction. The proposed pit material would be directly removed from the following on-site jurisdictional streams: 1,090 linear feet of Intermittent Stream 3, 548.5 linear feet of Intermittent Stream 8, 249 linear feet of Perennial Stream 8, 76.5 linear feet of Intermittent Stream 9, 520 linear feet of Intermittent Stream 10, and 30 linear feet of Intermittent Stream 11 (Figures 6-8, Appendix A). The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill material would also be free of toxic pollutants in toxic amounts. All fill material would be clean fill material originating on site from adjacent areas to be mined and readily available to the applicant. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that the substrate of remaining waters of the United States would not change or be affected. Impacts 8 — 16: Those associated with waste rock area construction. The proposed waste rock material would be placed directly in the following on-site jurisdictional streams: 917 linear feet of Intermittent Stream 12, 755 linear feet of Perennial Stream 12, 240 linear feet of Intermittent Stream 8, 76.5 linear feet of Intermittent Stream 9, 240 linear feet of Intermittent Stream 13, 1,125.5 linear feet of Intermittent Stream 15, and 81 linear feet of Perennial Stream 15 (Figures 9-11, Appendix A). The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill material would also be free of toxic pollutants in toxic amounts. All fill material would be clean fill material originating on site from adjacent areas to be mined and readily available to the applicant. Proper 2 Norton, J. and McKenney Schlegel, D. 1955.

Typical construction equipment such as bobcats, dump trucks, and excavators would also provide construction support. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that remaining waters of the United States would not change or be affected. Block 23. Description of Avoidance, Minimization, and Compensation According to the applicant, the applicant's preferred alternative would avoid impacts to the entirety of Beaverdam Creek (13,741 feet) and Little Beaverdam Creek (2,848 feet). Impacts to Stream 2 have been minimized through utilization of the footprint of an existing crossing for an access road, and impacts to the majority of the stream have also been avoided (1,762 feet). Avoiding disturbance in the FEMA floodplain will prevent impacts to the entirety of Wetlands 1, 3-8, and 11-14 (7.62 acres). Wetlands 2, 10, and 15-16 (0.40 acre) will also be avoided due to site design. Finally, adhering to the 300 -foot mining buffer setback as required by Gaston County Zoning Ordinance, the preferred alternative also avoids impacts to 10,603 feet of stream. Indirect impacts to remaining streams will be avoided through the use of 100 -foot stream buffers and stormwater management through NPDES BMPs. The applicant has considered alternatives including off-site alternatives, a no -build option, an on-site no impact option, an on-site additional impact option, and an on-site avoidance option. Construction equipment would be kept in upland areas. Sediment and erosion control measures would be used to prevent impacts to downstream waters. No live Page 15 ENG Form 4345 Supplemental Document Piedmont Lithium SAW -2018-01129 concrete would be allowed to come in contact with surface waters. Water quality monitoring would be conducted to monitor site discharge and runoff. A Section 401 Individual Water Quality Permit is being submitted concurrently with this IP application. A Stormwater Pollution Prevention Plan (SWPP) is also being developed and will be submitted upon completion to the North Carolina Department of Environmental Quality (NCDEQ) Division of Energy, Mineral, and Land Resources (NCDEMLR) under the General Permit (No. NCG020000) for Mining Activities. There are no active private mitigation banks within HUC 03050102; therefore, the applicant proposes compensatory mitigation for all permanent impacts through the purchase of stream and wetland mitigation credits from the North Carolina Division of Mitigation Services (DMS). The applicant provided supporting documentation from DMS in a letter dated December 21, 2018 (attached to the Environmental Assessment in Appendix C), indicating that they are willing to accept compensatory mitigation payment for 5,810.5 linear feet of stream impacts and 0.14 acre of riparian wetland within the South Fork Catawba Sub -Basin within the Catawba River Basin (03050102).

Project location Page 2 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 1.3 Description of activity requiring permit: The proposed project would involve the development of a hard rock lithium mine, which includes the construction of an open pit, a waste rock area, a concentrator plant site, access roads, and applicable National Pollutant Discharge and Elimination System (NPDES) best management practices (BMPs). The project would result in impacts to 1,263 linear feet of perennial stream channel and 4,547.5 linear feet of intermittent stream channel (5,810.5 linear feet total), 0.14 acre of wetlands, and 0.16 acre of pond. Approximately 781 linear feet of perennial stream channel, 2,283 linear feet of intermittent stream channel, 0.14 acre of wetlands, and 0.16 acre of ponds will be impacted by waste rock areas. Approximately 249 linear feet of perennial stream channel and 2,264.5 of intermittent stream channel will be impacted by pit shell areas (Figure 2). Approximately 178 linear feet of perennial stream channel will be impacted by an internal access road stream crossing and 55 linear feet of perennial channel will be impacted by a stormwater BMP.

Proposed impacts to Waters of the US The Piedmont Lithium mine would generate approximately 11.2 million cubic yards of lithium bearing spodumene ore and 83.2 million cubic yards of waste rock and tailings. The project proposes to extract lithium bearing spodumene from the open pit, which is within host rock in a geologic formation called a pegmatite dyke (Figure 3), and would then be separated into ore, waste, and byproduct.

Depiction of pegmatite dyke formation within host rock The separation of lithium bearing spodumene ore and marketable byproducts from the host rock would be conducted at an on-site concentrator plant. The project boundary has been developed to encompass open pits, waste rock areas, appropriate NPDES BMPs, internal access roads, the concentrator unit, and all other necessary support facilities. Large waste rock areas would be required to accommodate as much as all pit waste as possible since offsite removal of waste rock is not practicable due to the volume of material that would be generated. The full 200 -acre open pit areas and 145 -acre waste rock areas are needed for the applicant to meet the project purpose. The construction sequence would first require the establishment of 300 foot mining buffers around the entire perimeter of the project site as required by Gaston County. The Federal Emergency Management Act (FEMA) 100 -year floodplain would also be maintained along the entirety of Beaverdam and Little Beaverdam Creeks. Next, the sediment and erosion control measures would be installed around the perimeter of the site to control stormwater flows. The North Carolina Mine Permit requires that all sediment and erosion control measures such as ditches, ponds, rock dams, be designed for the 25 -year storm. Underdrains would be placed in the waste rock areas to capture normal groundwater flows in areas where existing streams will be filled. Additional NPDES BMPs would be installed in appropriate areas to treat stormwater runoff of the site in general as needed. Clearing of the pit and waste area sites would Page 4 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) occur before the open pit and waste rock area are constructed and only cleared as needed during the development of the pit and waste rock areas. Internal roads would be constructed for pit and waste rock area access throughout the mine site. The open pits will have design parameters similar to batter face angles of 80 degrees, a batter height of 40 feet (12.2 meters), a berm width of 20 feet (6.1 meters), an overall wall angle of 52 degrees, and a ramp width of 80 feet (24.8 meters) for transportation of material (Figure 4). 52'Over all Slope Anile _A ■ Inter Ramp Angie I 180 m Figure 4. Representation of the Piedmont pit wall design based on wall design configuration assumptions The waste rock area would contain as much pit waste as possible since offsite removal of waste rock is not practicable due to the volume of material that would be generated. The majority of remaining waste will be returned to the pit as backfill once pit voids have been established. A percentage of waste will also be separated as marketable byproducts, such as mica and feldspar. Filter cake waste from the concentrator will also be placed in the waste rock area and co - disposed with waste rock. The Piedmont Lithium site was acquired by the applicant for the purpose of managing all the aforementioned mining activities in close proximity to one another. The proposed impacts would result from the construction of open pits, waste rock areas, and one access road crossing. Page 5 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 1.3.1 Proposed avoidance and minimization measures: According to the applicant, the applicant's preferred alternative would avoid impacts to the entirety of Beaverdam Creek (13,741 feet) and Little Beaverdam Creek (2,848 feet). Impacts to Stream 2 have been minimized through utilization of the footprint of an existing crossing for an access road, and impacts to the majority of the stream have also been avoided (1,762 feet). Avoiding disturbance in the FEMA floodplain will prevent impacts to the entirety of Wetlands 1, 3-8, and 11-14 (7.62 acres). Wetlands 2, 10, and 15-16 (0.40 acre) will also be avoided due to site design. Finally, adhering to the 300 -foot mining buffer setback as required by Gaston County Zoning Ordinance, the preferred alternative also avoids impacts to 10,603 feet of stream. Indirect impacts to remaining streams will be avoided through the use of 100 -foot stream buffers and stormwater management through NPDES BMPs. The applicant has considered alternatives including off-site alternatives, a no -build option, an on-site no impact option, an on-site additional impact option, and an on-site avoidance option. Construction equipment would be kept in upland areas. Sediment and erosion control measures would be used to prevent impacts to downstream waters. No live concrete would be allowed to come in contact with surface waters. Water quality monitoring would be conducted to monitor site discharge and runoff. A Section 401 Individual Water Quality Permit is being submitted concurrently with this IP application. A Stormwater Pollution Prevention Plan (SWPP) is also being developed and will be submitted upon completion to the North Carolina Department of Environmental Quality (NCDEQ) Division of Energy, Mineral, and Land Resources (NCDEMLR) under the General Permit (No. NCG020000) for Mining Activities. 1.3.2 Proposed compensatory mitigation: There are no active private mitigation banks within HUC 03050102; therefore, the applicant proposes compensatory mitigation for all permanent impacts through the purchase of stream and wetland mitigation credits from the North Carolina Division of Mitigation Services (DMS). The applicant provided supporting documentation from DMS in a letter dated December 21, 2018 (attached), indicating that they are willing to accept compensatory mitigation payment for 5,810.5 linear feet of stream impacts and 0.14 acre of riparian wetland within the South Fork Catawba Sub -Basin within the Catawba River Basin (03050102). 1.4 Existing conditions and any applicable project history: The Piedmont Lithium project is located in the piedmont physiographic region of North Carolina and encompasses 971 acres of land in Gaston County. The project area is approximately 67% forested land, consisting of mixed medium Page 6 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) aged hardwoods (34%), pines (17%), and young successional growth (16%). The remaining areas (33%) are open crop fields, maintained pasture, or maintained residential areas. Surrounding land use is rural residential and agricultural, with a patchy landscape of discontinuous forested areas. Beaverdam Creek flows in a southeast to northeast to eastwardly direction, bisecting the project area. Little Beaverdam Creek flows northeast to a confluence with Beaverdam Creek in the approximate center of the project area. Jurisdictional aquatic resources within the project area include 11 unnamed tributaries to Beaverdam Creek, two unnamed tributaries to Little Beaverdam Creek, and 16 wetlands. At the time of this submittal, a portion of the site has been field -verified by the USACE on August 29, 2018 and on October 24, 2018; written verification has not yet been received. The majority of the site has been delineated and areas where the applicant's environmental consultant did not have access were estimated using desktop information. Therefore, this application references "desktop features" as depicted on Figure 5. These features have all been partially delineated either up or downstream and are good approximations of remaining jurisdictional features. These features are included in all impact calculations for this submission, as applicable. The applicant's environmental consultant will submit a second and final JD Verification Request for the remaining areas pending access. Page 7 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Figure 5. Jurisdictional features Elevations on the site range from a low of approximately 738 feet above Mean Sea Level (MSL) along Beaverdam Creek, to a high of approximately 912 feet MSL in the southeastern corner of the site. The Soil Survey of Gaston County, North Carolina (USDA-NRCS) depicts the project area as underlain by Cecil sandy clay loam and Lloyd sandy clay loam in upland areas of the site, Congaree loam along Beaverdam and Little Beaverdam Creeks, Chewacla loam in floodplain pockets, Pacolet sandy loam on steep slopes, and one occurrence of Udorthents in a northeast portion of the site. In July 2018, the applicant's environmental consultant installed five groundwater monitoring wells, four groundwater observation wells, and one groundwater pumping well to facilitate periodic groundwater level, water quality monitoring, and aquifer testing throughout the site. Depths to groundwater has been measured monthly starting July 2018 and will be measured through July 2019. To date, depths to water range from 8 to 48 feet, with the shallowest depths to water in the northeast of the site near Beaverdam Creek and the deepest depths to water in the northwest, southwest, and southeast reaches of the site. Generally the direction of groundwater flow is from southwest to northeast across the site. Bedrock was observed in the bottom of Beaverdam Creek during well installation; therefore, the hydrologic regime of on-site surface waters are influenced by both stormwater runoff from on-site forest land, agricultural fields, Page 8 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) pasture fields, and rural residences and by groundwater baseflow. Overbank flooding by Beaverdam and Little Beaverdam Creeks also influence their abutting and adjacent wetlands. The site has been observed by the environmental consultant over a period of a year and the on-site features have been observed throughout all seasons. Piedmont Lithium will acquire the necessary NCDEQ DEMLR General Permit for Mining Activities parallel to this IP review and will not commence work until approval. Approximately 217 acres (22%) of the site will be located in the 300 foot setback mine buffer and 109.5 acres (11 %) of the site is within the FEMA floodplain; neither of these areas will experience disturbance. Of the disturbed area, open pit would occupy 200 acres (21 %) of the site, waste rock area would occupy 145 acres (15%), and the concentrator site (6%) and mine operation structures would occupy 60 acres. Internal access roads consisting of existing roads and new roads will occupy approximately 53 acres (5%) of the site. The riparian areas along Beaverdam Creek, Little Beaverdam Creek, and their tributaries are dominated by various oaks (Quercus spp.), hickories (Carya spp.), loblolly pine (Pinus taeda), red maple (Acer rubrum), American beech (Fagus grandifolia), red cedar (Juniperus virginiana), tulip poplar (Liriodendron tulipifera), hornbeam (Carpinus caroliniana), sweetgum (Liquidambar styraciflua), river birch (Betula nigra), The understory vegetation consists of laurel (Rhododenron spp.), bamboo (Arundinaria spp.), spicebush (Lindera benzoin), strawberry bush (Euonymus americanus), Christmas fern (Polystichum acrostichoides), Chinese privet (Ligustrum sinense), autumn olive (Eleaganus umbellate), Japanese stilt grass (Microstegium vimineum). There is a FEMA 100 -year floodplain associated with both Beaverdam and Little Beaverdam Creeks within the project area. 1.5 Permit Authority: Section 404 of the Clean Water Act (33 USC 1344). 2.0 Scope of review for National Environmental Policy Act (i.e. scope of analysis), Section 7 of the Endangered Species Act (i.e. action area), and Section 106 of the National Historic Preservation Act (i.e. permit area) 2.1 Determination of scope of analysis for National Environmental Policy Act (NEPA): The scope of analysis includes the specific activity requiring a Department of the Army permit.

Among these is lithium (Li), a key component in lithium -ion batteries for electronic devices, particularly electric and hybrid vehicles, laptop computers, and cell phones. Forecasted growth in both global lithium demand and supply varies among analysts and industry experts; however, Roskill forecasts overall growth in lithium consumption to average 15.3% per year to 2027 (Roskill's Base -Case Scenario).2 Consumption of lithium will continue to be driven by the rechargeable battery sector, which is forecast to register 22.4% per year growth through to 2027.3 The global leaders in lithium supply are Australia, Chile, and Argentina at 37%, 36%, and 17%, respectively, while the U.S. supplies only 2% to the global market. And although there are untapped lithium reserves in the U.S., the U.S. imports two-thirds of the lithium needed to meet domestic demand. Expanding the lithium supply in the U.S. Bradley, D., Munk, L., Jochens, H., Hynek, S., and Labay, K. 2013. A preliminary deposit model for lithium brines.

Lithium -ion Batteries: Market Development & Raw Materials. https://roskill.com/market-report/lithium-ion-batteries/ Page 10 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) would ensure a domestic source and insulate domestic prices in a global market. Thus, a domestic lithium source is needed to supplement demands in the U.S. The main sources of lithium used in cathodes of lithium -ion batteries are spodumene (a mineral) and sub -saline brines. Lithium -ion batteries require lithium hydroxide (LiOH), which is expected to be the fastest growing product of the lithium market. Global Lithium, LLC projects sustained relatively firm lithium hydroxide pricing over the next five to seven years based on the consensus opinion of lithium producers, purchasers and industry experts that lithium demand to produce lithium hydroxide will grow a minimum of 300% between 2017 and 2025. To produce lithium hydroxide, lithium must be extracted from either hard rock sources such as spodumene or extracted through an evaporative process from sub -saline brines. Extracting spodumene-containing lithium is accomplished by utilizing traditional hard rock mining techniques of open pit drilling and separation of lithium from host rock using a series of physical and chemical processes to produce lithium concentrate. This process can be completed as fast as the material can be moved from an open pit to a concentrator plant. Saline -based projects rely upon pumping saline -containing lithium from underground reserves to the earth's surface, which is then pumped through a series of evaporation ponds, each having a higher concentration of lithium than the last. This process can take months to a year or more, depending on weather, to yield adequate lithium concentrate. Both spodumene- and saline -based projects require conversion of lithium concentrate through purification and crystallization into battery -grade quality lithium hydroxide of the type which can be used in cathodes for the manufacturing of electric car batteries. According to Roskill Industry Cost Curves, it is more cost efficient to produce battery -grade quality lithium hydroxide from lithium concentrates extracted from spodumene-based projects than with saline -based projects.' Lithium conversion with spodumene-based projects cost approximately $2,500 to $3,500 per metric tonne (1.1023 US tons) of lithium hydroxide produced while lithium conversion with saline -based projects cost approximately $4,500 to $6,500 per metric tonne of lithium hydroxide produced. Moreover, if lithium concentrates are shipped to China (a common practice in the industry) for this conversion/purification process (vs. on-site or nearby conversion locations), costs increase to approximately $7,500 to $9,500 per metric tonne of lithium hydroxide produced. Since spodumene-based lithium extraction projects are more cost efficient than saline -based lithium extraction projects to produce battery -grade lithium hydroxide and since there is a need for a domestic supply of lithium, spodumene reserves containing lithium located in the U.S. were considered for development. Spodumene based lithium reserves located outside the US were not considered reasonable or practicable alternative to provide domestic sources of lithium. While there are a few lithium reserves contained in mineralized spodumene in 4 Roskill Market Reports and Consultancy. 2018. Lithium Industry Cost Curves. https://roskill.com/roskill-product/lithium-industry- cost-curves/ Page 11 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) the US, the largest lithium reserves are located within the Carolina Tin- Spodumene Belt (TSB), in North Carolina, according to the US Geological Survey (USGS).5 The Carolina TSB was the world's largest producer of lithium after World War II, from the 1950's through the 1980's and infrastructure such as rail and highway are still existing which can be utilized to access and support mining operations today.6 An attractive draw for potential investors and local labor forces, the Carolina TSB is also close (< 30 minutes) to multiple metropolitan areas, such as Gastonia and Charlotte. Therefore, the purpose of the project is to develop a hard rock lithium mine in the Carolina TSB, to extract and refine mineralized spodumene to a high quality lithium bearing spodumene concentrate; which, upon conversion to a battery grade lithium hydroxide, will provide a domestic source of lithium to meet growing demands in the U.S. 3.2 Basic project purpose, as determined by the Corps: Select N/A or basic purpose here. 3.3 Water dependency determination: Select correct choice.

An evaluation of alternatives is required under NEPA for all jurisdictional activities. An evaluation of alternatives is required under the Section 404(b) (1) Guidelines for projects that include the discharge of dredged or fill material. NEPA requires discussion of a reasonable range of alternatives, including the no action alternative, and the effects of those alternatives; under the Guidelines, practicability of alternatives is taken into consideration and no alternative may be permitted if there is a less environmentally damaging practicable alternative. 5.1 Site selection/screening criteria: In order to be practicable, an alternative must be available, achieve the overall project purpose (as defined by the Corps), and be feasible when considering cost, logistics and existing technology. Criteria for evaluating alternatives as evaluated and determined by the Corps: A. Hard Rock Mine (technology and cost): The alternative would only be considered practicable and achieve the overall project purpose if it relied on open pit, hard rock mining techniques. This is a surface mining method of Page 13 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) extracting a resource from an open pit in the earth's surface, utilizing drilling and construction machinery. Because industry data concludes it is more cost efficient to mine lithium from spodumene-based projects than with saline - based projects,' spodumene containing lithium is the resource target; therefore, open pit, hard rock mining techniques will be utilized. An open pit, hard rock mine is the best mining technique for spodumene extraction because the mineral is contained within host rock present at, or near, the earth's surface. The extraction process begins at the pit's surface and goes downward, narrowing as the pit becomes deeper — the pit will look like an upside-down wedding cake, with the pit width largest at the surface and pit width smallest at the deepest part of the pit. This mining process happens as fast as the material can be extracted and concentrated, on a scale of a few weeks to months. Also, the surface area footprint for an open pit lithium mine is much smaller at a few hundred acres than that of what is needed for the brine extraction process. Brine mining is an alternative to open pit, hard rock lithium mining, and is the extraction of lithium that is naturally dissolved in a brine/saline solution. The saline solutions may be contained in salt lakes or salars (salt -encrusted depressions) on the earth's surface or underground in saline groundwater that are enriched in dissolved lithium; however, in the U.S. those brine -containing lithium reserves are underground reserves. Saline brines -containing lithium are pumped from underground reserves to the earth's surface. Once at the surface, the solution is pumped through a series of evaporation ponds, each having a higher concentration of lithium than the last. The evaporative process can take months to a year or more to obtain adequate lithium concentrates. This mining method is limited to arid climates, is highly dependent on weather, depletes groundwater aquifers, and requires thousands of acres of surface area for the evaporation ponds. Overall, the open pit, hard rock mining method for spodumene-based projects is more cost efficient, is not dependent on weather or climate, can yield adequate spodumene-containing lithium concentrate over a smaller footprint and in a faster timeframe than mining lithium from saline -based projects. Therefore; to achieve the project purpose of extracting spodumene-containing lithium, the alternative would only be considered practicable if it relied upon open pit, hard rock mining techniques. B. Location within Carolina Tin-Spodumene Belt with Previous Exploration History (logistics): The alternative would only be considered practicable and achieve the overall project purpose if it is located within the Carolina Tin- Spodumene Belt (TSB) and if there was a history of previous exploration with Roskill Market Reports and Consultancy. 2018. Lithium Industry Cost Curves. https://roskill.com/roskill-product/lithium-industry- cost-curves/ Page 14 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) positive identification of mineralized spodumene within the alternative identified. The USGS Mineral Resource Potential for Lithium in North and South Carolina estimates the TSB to be approximately 24.5 miles long, 1.8 miles in maximum width, extending southwestward from Lincolnton, North Carolina to Gaffney, South Carolina .8 Currently, the TSB contains the largest North American lithium reserves (contained in spodumene),9 estimated to contain 6.5 million tons (5.9 million metric tonnes) of lithium.10 Compared to the total estimated domestic supply of 11.2 million tons (10.2 million metric tonnes), the TSB contains over half of the U.S. lithium supply.11 Also, according to the U.S. Department of the Interior, spodumene-based lithium mines in the TSB were historically the world's leading producer of lithium after World War II, from the 1950s to the 1980s.12 The historic knowledge (old mines) of mineralized spodumene locations within the TSB helped to immediately narrow potential mine sites and save capital exploration costs, according to the applicant. Given the documentation and proven existence of the resource in the TSB, the project should be located on previously explored properties within the TSB. C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative would only be considered practicable and achieve the project purpose if an initial core parcel of at least 120 acres is identified to warrant the assembly of other adjacent properties into a larger project area of approximately 900 to 1,100 acres. This total mine area is of sufficient size to extract the minimum amount of mineralized spodumene to produce sufficient lithium hydroxide needed to balance capital investment costs and to operate a mine designed to Mine Safety and Health Administration (MSHA) standards, while also observing local and state requirements, such as a 300 -foot wide mine buffer setbacks required by Gaston County Zoning Ordinance. According to the applicant, a minimum of 14.3 million tons or more (roughly 17 million cubic yards) of mineralized spodumene is required to produce approximately 265,500 tons of battery grade lithium hydroxide, which is the minimum volume needed to be attractive to capital investors. Ideally, the total mine area would handle an open pit design that captures adequate mineralized spodumene needed to offset capital investment cost, in areas where the resource presence was confirmed, waste rock areas that handle at as much as all pit waste as possible, a site for the concentrator plant, internal 8 Horton, J.W., Jr. 1987.

Table 1 (below), summarizes an approximate minimum total area needed to accommodate all mine features. Table 1. Approximate area needed to accommodate reasonable mine design. Mine Feature Minimum Area Needed Pit Shell ± 200-300 ac. Waste Rock Area ± 140-200 ac. Concentrator Plant Site ± 60-70 ac. Mine Buffers, Erosion Control, Access Roads ± 250-450 ac. Basic Mine Features ± 400-570 ac. Property Dependent Mine Design Features ± 200-450 ac. Total Mine Area Needed ± 650-1,020 ac. Comparatively, the historic Hallman Beam lithium mine (Off -Site Alternative 2) and the historic Foote Lithium Mine (Off -Site Alternative 3) were both roughly 700 acres; however, during these mines' operation between the 1930s to 1990s, environmental requirements, such as buffers and sediment and erosion control practices, most likely did not require as much land to accommodate. Currently, there are no operational lithium mines in the area for size comparison. Given that there are few large parcels (>_120 acres) remaining in the TSB, all those parcels identified of this size or greater are examined as off-site alternatives in Section 5.2.2. D. Property Availability (logistics): The alternative would only be considered practicable and achieve the project purpose if it the current land owner(s) would be willing to sell or lease the core parcel alternatives identified. E. Minimization of Environmental Impacts: The alternative would only be considered practicable and achieve the overall project purpose if only a minimum of environmental impacts are required. A desktop analysis of environmental impacts will be assessed for each alternative utilizing the publically available National Wetland Inventory (NWI) and National Hydrography Dataset (NHD) datasets. Additionally, those NWI and NHD features depicted within 100 -Year Federal Emergency Management Act (FEMA) Floodplains are assumed to be avoided due to the additional permitting associated with impacting floodplains. Therefore, this allows for equal comparison across off-site alternatives of NWI and NHD features outside FEMA floodplains. 5.2 Description of alternatives Page 16 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 5.2.1 No action alternative: Under the no action alternative, a hard rock lithium mine would not be constructed in the TSB and battery grade lithium hydroxide, made from lithium bearing spodumene concentrates produced from hard rock mining, would not be brought to the U.S. market from a domestic source to supplement current needs. The majority of lithium chemicals would still be imported from outside the U.S. to meet the domestic demand. If the majority of lithium chemicals were imported to the U.S. the cost of these chemicals would ultimately drive up prices of lithium - ion batteries and products that use them such as electric vehicles. Due to this factor, the no action alternative is not considered a practicable alternative. This alternative would not satisfy the following screening criteria: B. Location within Carolina Tin-Spodumene Belt with Previous Exploration History (logistics): The alternative would not occur and would therefore not occur within the TSB. C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative would not occur and would therefore not provide minimum size needed to produce lithium hydroxide as a domestic supply. D. Property Availability (logistics): The alternative would not occur; therefore, property availability would not be considered practicable and achieve the project purpose. E. Minimization of Environmental Impacts: It can be assumed that there are environmental impacts associated with mines located outside the U.S., especially in areas where environmental regulations may be less stringent, although the amount of impacts is unknown. This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): There are hard rock lithium mines outside the U.S. 5.2.2 Off-site alternatives Off-site alternatives include alternatives located outside the TSB, which were eliminated from consideration as it was not considered practicable or achievable within the scope of the project's purpose and need. In addition to the Preferred Alternative, three other off-site alternatives are discussed. Figure 6 (below) illustrates the off-site alternatives discussed in the alternatives analysis relative to their location to the Preferred Alternative in the TSB.

Page 18 of 85 Gaston County, North Carolina CE SAW -RG -C (File Number, SAW 2018-01129) Off-site alternative 1: Constructing a hard rock lithium mine outside the Carolina Tin-Spodumene Belt: According to the applicant, the demand for lithium hydroxide will grow at least 300% between 2017 and 2025 due to its use in lithium -ion batteries principally to power electric vehicles. Currently, the U.S. imports approximately two-thirds of lithium chemicals needed to meet domestic demand. As demand grows, the U.S. would need to import more lithium hydroxide to meet demand for lithium chemicals. A number of active lithium mines are operational on the international stage, some are large in scale, and have been operational for a number of years. Entering into the international market to provide lithium chemicals to the U.S. would be difficult to accomplish in a competitive manner. In order for a lithium mining operation to be feasible, the extracted resource must be present and of a suitable quality so that it can be mined, processed, and used for downstream lithium chemical production, specifically lithium hydroxide. As discussed in the purpose and need, and reported by USGS, the Carolina TSB contains the largest North American lithium reserves within mineralized spodumene;13 therefore, based on current known reserves, it would not be economically feasible to locate a hard rock lithium mine in the United States outside the Carolina TSB. It is unlikely that sufficient mineralized spodumene containing lithium for a domestic supply would be available outside the TSB. Alternatives located outside the TSB were eliminated from consideration because it was determined that constructing a hard rock lithium mine outside the TSB would be unreasonable considering the overall project purpose and the presence and quantity of the resource within the Carolina TSB. 13 Norton, J. and McKenney Schlegel, D. 1955.

However, this core parcel is not for sale, Martin Marietta intends to continue processing construction aggregates on the site, and it would require the acquisition of 44 more parcels under multiple ownerships (33% of the land area). Moreover, if the land were available for purchase, the applicant believes the land would be unsuitable for lithium mining as the former lithium mine depleted the resource beyond sufficient volume needed to offset capital investment costs. The closure of Hallman -Beam in 1998 corroborates the lack of sufficient resource. The unavailability of the land for purchase in combination with a lack of sufficient resource to cover capital investments costs means that this alternative is not practicable. See Table 5 at the end of this section for the alternatives analysis siting criteria summary. This alternative would not satisfy the following screening criteria: D. Property Availability (logistics): The alternative is not available for purchase. E. Minimization of Environmental Impacts: This alternative has the 2nd highest amount of NHD and NWI features that are potentially subject to impacts; therefore, it is not the least damaging alternative. This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): The alternative is currently a construction aggregates processing facility and mining infrastructure is already available, though this infrastructure is not well suited to processing spodumene and a substantial retrofit would be necessary, thus increasing costs. B. Location within Carolina TSB with Previous Exploration History: The alternative is both within the TSB and at least 25% of the area was the former Hallman -Beam lithium mine, substantiating the previous exploration history of mineralized spodumene.

Unfortunately, the core parcel is divided by a major highway (1-85), thus separating the alternative's total area. This site, or parts of this site, were once part of the Foote Lithium Mine, owned and operated from 1938 to its closure in the 1980s by the Foote Mineral Company. The historic Foote Lithium Mine was one of the largest producers of lithium between the 1930s and the 1980s and has historic production records of lithium chemicals. Through a series of land mergers, Rockwood Lithium acquired the land in 2012. Rockwood Lithium was Page 22 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) acquired by Albemarle Corporation in 2015, a global company that specializes in lithium chemicals, among others. The strategic purchase of Rockwood Lithium by Albemarle Corporation (Figure 8), leads the applicant to believe that there is sufficient mineralized spodumene within the site, or in adjacent land holdings, to warrant a restart of a hard rock lithium mine at this location; however, the amount of spodumene reserves are unknown. Moreover, the site has not been mined for many years and much of the land has been reclaimed and naturalized, including the on-site aquatic resources. For equal comparison across alternatives, a desktop analysis of NHD and NWI features for the alternative was performed and these features would be subject to potential impacts.

Therefore, due to the unavailability of the land for purchase, the unknown amount of resource reserves remaining, and potentially considerable aquatic resource impacts, this alternative would not be practicable. See Table 5 at the end of this section for the alternatives analysis siting criteria summary. This alternative would not satisfy the following screening criteria: D.

The alternative is currently a mica mine, owned and operated by Imerys Mica Kings Mountain Inc. The site appears to have been in operation as a mica mine since prior to the 1960s. To the best of the applicant's knowledge, this site is not known Page 24 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) to contain lithium reserves and it has not been historically mined or explored for lithium. There are no known records to substantiate the presence of mineralized spodumene within the site. For equal comparison across alternatives, a desktop analysis of NHD and NWI features for the alternative was performed. These features would be subject to potential impacts for this alternative.

The mica resource has likely not been depleted and mining operations are ongoing at the site. The combination of unavailability of the land for purchase, and the lack of exploration for mineralized spodumene result in this alternative being impracticable. See Table 5 at the end of this section for the alternatives analysis siting criteria summary. This alternative would not satisfy the following screening criteria: B. Location within Carolina TSB with Previous Exploration History: The alternative is not known to contain lithium reserves and does not have a history of exploration for lithium containing -mineralized spodumene. It is unknown if the alternative could provide adequate mineable lithium reserves to cover capital investments costs. C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative core parcel size is of sufficient size; however, the total mine area is 602 acres and is less than the target area needed. Moreover, the alternative is divided by a major highway (I-85). D. Property Availability (logistics): The alternative is not available for purchase. E.

Preferred Alternative There are 74 parcels associated with this preferred alternative, of which 48 parcels (78% of the land area) are controlled by the applicant, including the core parcel. The core parcel and immediately adjacent areas in the preferred alternative boundary were originally explored by Lithium Corporation of America, which was eventually acquired by FMC Corporation. A Canadian exploration company, North Arrow Minerals, completed a 19 drill-hole, 2,544 meter (8,346 feet) exploration drill program on the alternative in 2009-2010, which confirmed the presence of lithium -bearing mineralized spodumene. Upon the acquisition of this data and knowledge of the resource presence, the applicant acquired the 120 -acre parcel, and many adjacent parcels to create a larger contiguous area, which is now considered the applicant's preferred alternative of 971 acres. Subsequently, the applicant commenced additional exploration with a 230 -drill hole, 35,293 meter (115,790 feet) drilling program between 2017 and 2018 on the property. The acquisition of the 2009-2010 North Arrow drilling data enabled the applicant to target a property with the resource present and ultimately save on capital exploration costs during the subsequent 2017-2018 drilling program. For equal comparison across alternatives, a desktop analysis of NHD and NWI features for the preferred alternative was performed. These features would be subject to potential impacts. Table 6 summarizes the potential environmental impacts to NHD and NWI features for this alternative. Page 27 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Table 6.

Ponds none " excludes NWI / NHD features within FEMA floodplain Since this alternative can be developed as a hard rock lithium mine, is within the TSB, contains a core parcel of sufficient size to warrant the assembly of parcels for a larger area, the applicant was able to acquire the core parcel along with many other adjacent parcels; and, as the preferred alternative contains the least amount of NHD and NWI features outside the floodplain of all the alternatives potentially subject to impacts, this alternative was carried forward as the preferred alternative. This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): The alternative creates the opportunity to develop a hard rock lithium mine using proven hard rock mining techniques to extract mineralized spodumene. No retrofit of existing technology is required. B. Location within Carolina TSB with Previous Exploration History: The alternative and has a history of previous exploration for mineralized spodumene, which substantiates the inferred and indicated resource amounts of the existing resource. Moreover, the applicant has commenced their own drilling program on the alternative, thus increasing the confidence of the resource presence and location. C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative core parcel size is of sufficient size and is also surrounded by other land parcels already consolidated under control of the applicant. The preferred alternative mine area is 971 acres and is sufficient to accommodate the necessary size and design of the pit shell, waste rock areas, and attendant mine features. The alternative is also large enough to accommodate perimeter buffers, sediment and erosion controls, internal access roads, and other features as approved by the approved mine design D. Property Availability (logistics): The core parcel and 78% of the preferred alternative is under the applicant's control. Negotiations are currently ongoing for control of the remaining 22%. The applicant is confident that 100% control will occur in 2019. Page 28 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) E. Minimization of Environmental Impacts: This alternative has the least amount of NHD and NWI features that are potentially subject to impacts; therefore, it is the least damaging alternative. The FEMA floodplain, features within the FEMA floodplain, and perennial streams originating offsite are avoided. Buffers will be placed on remaining aquatic features. In summary, the Preferred Alternative meets all of the siting criteria to be practicable and achievable within the scope of the project's purpose and need. It is the least environmentally damaging alternative when comparing sites equally using publically available datasets. See Table 5 in the previous section for a summary of the siting criteria used in the alternatives analysis and how the preferred alternative was chosen. Once the Preferred Alternative was chosen over the other off-site alternatives using the siting criteria, multiple on-site alternatives were examined to determine the best fit of mine features that can be practicably achieved within the project's scope, while also balancing the mandate of avoidance and minimization to the highest degree. These include the Applicant's Preferred Site Layout (On -Site Alternative 1), a No Impact Site Layout (On -Site Alternative 2), a More Impact Site Layout (On -Site Alternative 3), and an Avoidance Site Layout (On -Site Alternative 4), discussed below. Page 29 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) On-site alternative 1 (applicant's preferred alternative): On -Site Alternative 1 — Applicant's Preferred Site Layout: The applicant's preferred site layout was designed based on the data collected during the drilling program conducted by the applicant, targeting areas of spodumene mineralization (Figure 11 and Figure 12). Additionally, jurisdictional determination field work was conducted by the applicant's consultant to locate jurisdictional streams, wetlands, and ponds for impact determination.

Concentrator plant site It was determined that approximately 12.3 million tons (11.2 million metric tonnes) or more of mineralized spodumene can be extracted over a 13 year span, utilizing an approximately 200 -acre pit shell design. The waste rock areas are approximately 145 acres and will contain roughly 24% (19.4 million cubic yards) of the waste produced, the most of all the on-site alternatives. Any remaining waste will be placed in the pit shell as backfill once final pit shell voids have been defined. The pit shell and waste rock area designs include set parameters for wall angles, ramp widths, and high wall angles, widths, and heights necessary for stability and safety, while also avoiding FEMA floodplains that bisect the alternative, major drainages, and streams originating off site. Proposed impacts to jurisdictional waters include approximately 5,810.5 linear feet of stream, 0.14 acre of wetlands, and 0.16 acre of pond (Table 7). Approximately 781 linear feet of perennial stream channel, 2,283 linear feet of intermittent stream channel, 0.14 acre of wetlands, and 0.16 acre of ponds would be impacted by waste rock areas. Approximately 249 linear feet of perennial stream channel and 2,264.5 of intermittent stream channel would be impacted by pit shell areas. Approximately 178 linear feet of perennial stream channel would be impacted by a stream crossing for an internal access road, and 55 linear feet of perennial channel will be impacted by a BMP (Figure 2). All waste rock areas are designed with underdrains at low points to capture groundwater discharges Page 31 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) and all pit shell areas are designed with sump collection which would be pumped to NPDES BMPs for treatment, as required by NCDEQ DEMLR under the General Permit (No. NCG020000) for Mining Activities. Table 7. Approximate impact amounts for On -Site Alternative 1 (applicant's preferred alternative). Internal access roads within the Preferred Site Layout utilize existing roads or are located in areas within the pit and waste rock areas. At this time, the applicant is proposing to NCDOT to abandon the existing roads within the project site. Coordination with NDOT is ongoing and at this time, and no impacts associated with road relocation are anticipated. The Mine Safety and Health Administration (MSHA) requires design road widths to be 2.5x the width of mine trucks utilized. The applicant will utilize 70 ton mine haul trucks, which are 40 feet in width; therefore, internal access roads would be at minimum 100 feet in width with additional width as needed once road embankments and fill slopes are designed. Existing roads would be retrofitted/widened as necessary to MSHA standards. The largest pit, largest waste rock area, and the concentrator plant site can all be accessed without road crossings of aquatic features. The existing bridge crossing of Hephzibah Church Road would be reinforced and utilized to avoid impacts associated with a necessary crossing of Beaverdam Creek to access the eastern pit and waste rock area. Two internal access road stream crossings are needed to access pit areas separated by major perennial drainages in the north and south of the site. The proposed crossing in the north of the site is designed to utilize the footprint of an existing culverted crossing to minimize impacts (Figure 13). Approximately 178 linear feet of perennial stream channel will be impacted by this crossing. The crossing will most likely be a reinforced concrete pipe (RCP) and be designed to handle the 100 -year storm event once design is finalized.

To access the southern pit area, a crossing of Beaverdam Creek is proposed in the southwest of the Preferred Site Layout at the narrowest width of the FEMA floodplain. This crossing will be designed with an arch span bridge to horizontally and vertically avoid the 100 -year flood elevation entirely; therefore, this crossing will not impact Beaverdam Creek or the FEMA floodplain. The 971 -acre Preferred Alternative is large enough to accommodate the Preferred Site Layout with a 200 -acre pit shell, 145 -acre waste rock area, a 60 - acre concentrator plant site, 200 acres within the 300 -foot mine setback buffer, internal access roads, and sediment and erosion control measures in order to extract sufficient ore (12.3 million tons or more of mineralized spodumene) to produce approximately 264,500 tons of lithium hydroxide. According to the applicant, this amount of lithium hydroxide would be an adequate supply of lithium to be economically viable, attractive to long-term capital investors, and sufficient as a domestic supply of lithium. This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): The alternative creates the opportunity to develop a hard rock lithium mine using proven hard rock mining techniques to extract mineralized spodumene. No retrofit of existing technology is required. Page 33 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) B. Location within Carolina TSB with Previous Exploration History: The alternative and has a history of previous exploration for mineralized spodumene, which substantiates the inferred and indicated resource amounts of the existing resource. Moreover, the applicant has commenced their own drilling program on the alternative, thus increasing the confidence of the resource presence and location. C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative core parcel size is of sufficient size and is also surrounded by other land parcels already consolidated under control of the applicant. The preferred alternative land area is of adequate size to accommodate the necessary size and design of the pit shell, waste rock areas, and attendant mine features. The alternative is also large enough to accommodate perimeter buffers, sediment and erosion controls, internal access roads, and other features as approved by the approved mine design. D. Property Availability (logistics): The core parcel and 78% of the preferred alternative is under the applicant's control. Negotiations are currently ongoing for control of the remaining 22%. The applicant is confident that 100% control will occur in 2019. E. Minimization of Environmental Impacts: This alternative has the least amount of NHD and NWI features that are potentially subject to impacts; therefore, it is the least damaging alternative. The FEMA floodplain, features within the FEMA floodplain, and perennial streams originating offsite are avoided. Buffers will be placed on remaining aquatic features. See Table 10 at the end of this section for a summary of the on-site alternatives analysis. On-site alternative 2: On -Site Alternative 2 — No Impact Site Layout: This alternative consists of a pit shell design and waste rock areas completely located in upland portions of the preferred alternative while entirely avoiding impacts to Waters of the United States (Figure 14). This would result in pit shell and waste rock area designs that are smaller than the preferred concept. To have a no impact scenario, this design would also not have internal access roads due to impacts to streams for crossings, thus separating the most northern and southern pits from access to the concentrator plant site.

Figure 14. No Impact Site Layout (On -Site Alternative 2) Avoiding all aquatic features in this alternative would reduce the acreage of the pit shell and waste rock areas, diminish the mine life to 9 years, and decrease the amount of mineable mineralized spodumene to approximately 9.7 million tons (roughly a 29% reduction from the preferred alternative). This alternative would generate the least amount of waste (62.2 million cubic yards) of all the alternatives; however, the waste rock area design is only capable of handling 12% (8 million cubic yards) of the waste generated, and is the least capable of the alternatives for waste capacity. Furthermore, this volume of spodumene will only convert to a volume of approximately 137,700 tons of lithium hydroxide — an almost 50% reduction in lithium hydroxide produced compared to the preferred alternative, essentially cutting the potential domestic supply of lithium by half. According to the applicant, prospective investors would not be enthusiastic about the short mine life or the insufficient amount of lithium hydroxide produced for the project. Additionally, as the no impact pit shell mineable area decreases, the pit shell perimeter would increase in a non-linear fashion as it circumvents drainage features. This prevents the technique of utilizing long stretches of linear batter and berms, which would reduce mining efficiency and increase operational costs. Essentially, this alternative does not practicably achieve a no impact scenario while locating the pit shell, the waste rock areas, and the concentrator plant Page 35 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) entirely in uplands. Therefore, this alternative is not practicable or reasonable for the project purpose and need This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): The alternative creates the opportunity to develop a hard rock lithium mine using proven hard rock mining techniques to extract mineralized spodumene. No retrofit of existing technology is required. B. Location within Carolina TSB with Previous Exploration History: The alternative and has a history of previous exploration for mineralized spodumene, which substantiates the inferred and indicated resource amounts of the existing resource. D. Property Availability (logistics): The core parcel and 78% of the preferred alternative is under the applicant's control. Negotiations are currently ongoing for control of the remaining 22%. The applicant is confident that 100% control will occur in 2019. E. Minimization of Environmental Impacts: This alternative has the least amount impacts to aquatic features. This alternative would not satisfy the following screening criteria: C. Core Parcel Size & Mineable Area Needed for Reasonable Mine Design (logistics): The alternative core parcel size is of sufficient size and is also surrounded by other land parcels already consolidated under control of the applicant. However, the no impact alternative that avoids all aquatic features decreases the ability for mining the necessary amount of mineralized spodumene to meet project goals and contains as much as all pit waste as possible since offsite removal of waste rock is not practicable due to the volume of material that would be generated. Moreover, the no impact design is not practicable as two pits cannot be accessed without impacts for access roads, thus further decreasing the mineable area. See Table 10 at the end of this section for a summary of the on-site alternatives analysis. On-site alternative 3: On -Site Alternative 3 — More Impact Site Layout: The applicant considered a site layout with a larger pit area, targeting areas of spodumene mineralization (Figure 15). This site layout is similar to the applicant's preferred site layout except for this design's central and northern pits are combined, thus impacting an additional 1,430 linear feet of perennial stream that originates off site.

More Impact Site Layout (On -Site Alternative 3) This alternative would extract roughly 14.3 million tons of mineralized spodumene, utilizing an approximately 215 -acre pit shell design; however, the waste rock areas design is the same as the preferred alternative. As such, this alternative will generate more waste from the larger pit design (108 million cubic yards), but the waste rock areas would only handle 18% (19.4 million cubic yards) of pit -generated waste. Any remaining waste would be placed in the pit shell as backfill once final pit shell voids have been defined. Impacts for this alternative include approximately 7,185.5 linear feet of stream, 0.14 acre of wetlands, and 0.16 acre of pond (Table 8). Approximately 781 linear feet of perennial stream channel, 2,283 linear feet of intermittent stream channel, 0.14 acre of wetlands, and 0.16 acre of ponds would be impacted by waste rock areas. Approximately 1,857 linear feet of perennial stream channel and 2,264.5 of intermittent stream channel would be impacted by pit shell areas. Approximately 178 linear feet of perennial stream channel would be impacted by a stream crossing and 55 linear feet of perennial channel would be impacted by a BMP. All waste rock areas are designed with underdrains at low points to capture groundwater discharges and all pit shell areas are designed with sump collection which would be pumped to NPDES controls for treatment, as required by NCDEQ DEMLR under the General Permit (No. NCG020000) for Mining Activities.

Internal access roads within this alternative are the same as On -Site Alternative 1; however, impacts associated with the proposed road crossing for access to the northern pit would no longer be needed as this area would already be impacted by the pit. To access the southern pit area, a crossing of Beaverdam Creek is proposed in the southwest of the Preferred Site Layout at the narrowest width of the FEMA floodplain. This crossing would be designed with an arch span bridge to horizontally and vertically avoid the 100 -year flood elevation entirely; therefore, this crossing would not impact Beaverdam Creek or the FEMA floodplain. This alternative would satisfy the following screening criteria: A. Hard Rock Mine (technology and cost): The alternative creates the opportunity to develop a hard rock lithium mine using proven hard rock mining techniques to extract mineralized spodumene. B.

The preferred alternative land area is of adequate size to Page 38 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) accommodate the necessary size and design of the pit shell for this alternative, but the waste rock areas would be insufficient to handle the pit waste generated. Between topographic and mine buffer setback constraints, it would not be achievable to increase the waste rock areas to handle the additional waste and; therefore, not practicable for the project's purpose. E. Minimization of Environmental Impacts: This alternative has the highest amount of impacts to jurisdictional features of approximately 1,400 linear feet more than the preferred alternative; therefore, it is the most environmentally damaging alternative and was eliminated from consideration. See Table 10 at the end of this section for a summary of the on-site alternatives analysis. On-site alternative 4: On -Site Alternative 4 — Avoidance Site Layout: The applicant considered a site layout with the same pit configuration as the preferred alternative, but with a smaller waste rock area (Figure 16).

However, two internal access road crossings are still needed to Page 40 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) access pit areas separated by major perennial drainages in the north and south of the site. The proposed crossing in the north of the site is designed to utilize the footprint of an existing crossing to minimize impacts (Figure 13). Approximately 178 linear feet of perennial stream channel would be impacted by this crossing. The crossing would most likely be a reinforced concrete pipe (RCP) and be designed to handle the 100 -year storm event once design is finalized.

The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill material would also be free of toxic pollutants in toxic amounts. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that the substrate of remaining waters of the United States would not change or be affected. The pipe will be buried 1 foot if larger than 48 inches in diameter or will be buried 20% of the diameter if less than 48 inches, so as not to impede low flows and aquatic life movement. Suspended particulates/turbidity: During construction, there may be a minimal increase in suspended particulates that may lead to increased turbidity downstream. However, the increase would be minimal and temporary due to the installation and maintenance of proper sediment and erosion control measures during construction and shortly thereafter. Water Quality: The proposed discharge of dredge and fill material should not cause increased chemical contamination levels within the aquatic ecosystem. Specifically, changes in clarity, color, odor, and taste of water in addition to possible chemical contamination would be minimized by the applicant's storm water management and sediment and erosion control plan. The proposed fill material would consist of a reinforced concrete pipe (RCP). Current patterns in water circulation: The proposed discharged dredge and fill material is not expected to modify current downstream water circulation patterns by obstructing flow, changing direction or velocity of water, or changing velocity or flow of circulation. Normal water fluctuations: There is an existing pipe at this location (77 linear feet), whose footprint will be utilized to minimize impacts. The new pipe will be placed appropriately as to not impede low flows as described above. The discharge of fill material associated with this impact is not anticipated to have more than a minimal effect on the downstream hydrologic regimes.

Impacts 6 and 7 — Impacts to Intermittent Streams 10 and 11 due to removal for pit construction. Table 12. Potential Impacts on Physical and Chemical Characteristics for Im acts 2 — 7. Discussion: Substrate: The proposed pit material would be directly removed from the following on-site jurisdictional streams: 1,090 linear feet of Intermittent Stream 3, 548.5 linear feet of Intermittent Stream 8, 249 linear feet of Perennial Stream 8, 76.5 linear feet of Intermittent Stream 9, 520 linear feet of Intermittent Stream 10, and 30 linear feet of Intermittent Stream 11. The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill Page 47 of 85 Minor Minor Physical and Chemical NSA No Negligible Effect Effect Major Effect Characteristics Effect Effect (Short (Long Term) Term) Substrate x Suspended particulates/ turbidity X Water x Current patterns and water circulation X Normal water fluctuations x Salinity gradients x Discussion: Substrate: The proposed pit material would be directly removed from the following on-site jurisdictional streams: 1,090 linear feet of Intermittent Stream 3, 548.5 linear feet of Intermittent Stream 8, 249 linear feet of Perennial Stream 8, 76.5 linear feet of Intermittent Stream 9, 520 linear feet of Intermittent Stream 10, and 30 linear feet of Intermittent Stream 11. The existing stream substrate in these areas would be buried/removed. The discharge would consist of suitable fill material and would not include any trash, debris, car bodies, asphalt, etc. The fill Page 47 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) material would also be free of toxic pollutants in toxic amounts. All fill material would be clean fill material originating on site from adjacent areas to be mined and readily available to the applicant. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that the substrate of remaining waters of the United States would not change or be affected. Suspended particulates/turbidity: During construction, there may be a minimal increase in suspended particulates that may lead to increased turbidity downstream. However, the increase would be minimal and temporary due to the installation and maintenance of proper sediment and erosion control measures during construction and shortly thereafter. Water Quality: The proposed discharge of dredge and fill material should not cause increased chemical contamination levels within the aquatic ecosystem. Specifically, changes in clarity, color, odor, and taste of water in addition to possible chemical contamination would be minimized by the applicant's storm water management and sediment and erosion control plan. The proposed fill material would consist of clean fill material originating from on site from the adjacent areas to be mined. The fill material used on-site would be clear and free of chemical contamination. Current patterns in water circulation: The proposed discharged dredge and fill material is not expected to modify downstream current water circulation patterns by obstructing flow, changing direction or velocity of water, or changing velocity or flow of circulation. Normal water fluctuations: For all Impacts 2-7, the affected watersheds are completely contained within the project area and are relatively small, headwater catchments. The discharge of fill material associated with this project is not anticipated to have more than a minimal effect on the downstream hydrologic regimes.

Discussion: Substrate: The proposed waste rock material would be placed directly in the following on-site jurisdictional streams: 917 linear feet of Intermittent Stream 12, 755 linear feet of Perennial Stream 12, 240 linear feet of Intermittent Stream 8, 76.5 linear feet of Intermittent Stream 9, 240 linear feet of Intermittent Stream 13, 1,125.5 linear feet of Intermittent Stream 15, and 81 linear feet of Perennial Stream 15.

The discharge of fill material associated with this project is not anticipated to have more than a minimal effect on the downstream hydrologic regimes. 6.4 Potential impacts on the living communities or human uses (Subparts D, E and F): 6.4.1 Potential impacts on the biological characteristics of the aquatic ecosystem (Subpart D 40 CFR 230.30). See Table 14: Page 51 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Table 14. Potential Imaacts on Bioloaical Characteristics for all Imaacts Discussion: Threatened and endangered species: See Section 10.1. Fish, crustaceans, mollusks, and other aquatic organisms. Discharges of dredge and/or fill material in the stream channels on the site would alter the food web in these locations by impacting animals, such as invertebrates, that make up the basis of a food chain. The release of contaminants or an increase in turbidity has the potential to negatively affect certain aspects of the food web in/downstream/surrounding these areas. Such releases may also potentially increase the opportunities for exotic species to colonize disturbed areas which can cause shifts in the makeup of the food web. However, sediment and erosion control measures would also be implemented to ensure that indirect/secondary effects to nearby aquatic organisms would also not be impacted. Impacts to primary food chain production within the waters of the US on the project site is expected to be minimal and temporary. The project site is similar to surrounding landscapes and does not represent a rare landscape or contain any unique landscape elements in general. As such, the activities in on-site waters are not expected to have more than a minimal/temporary effect on aquatic wildlife as there is available and similar habitat surrounding the project area for species to migrate and maintain primary food chain production. Other wildlife: The discharge of dredge and/or fill material has the potential to negatively affect breeding and nesting areas, escape cover, travel corridors, and preferred food sources for resident and migrant wildlife species in the immediate vicinity of the impact areas. Vegetation and trees would be removed which would eliminate existing and future habitat for terrestrial and avian species in the area. However, the avoidance of the FEMA floodplain preserves a forested and vegetated habitat corridor through the site. As such, the activity is not expected to have more than a minimal/temporary effect on wildlife as there is available and similar habitat surrounding the project area for species to migrate.

Page 52 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 6.4.2 Potential impacts on special aquatic sites (Subpart E 40 CFR 230.40). See Table 15: Refer to Figure 24 for the only impact to a special aquatic site (Impact 14 — Wetland 9). This impact is relatively minor at 0.14 acres of fill to Wetland 9. Table 15. Potential Imnacts on one Snecial Aauatic Site (Wetland 9). Discussion: Wetlands: The discharge of dredge and/or fill material has the potential to negatively affect wetlands on the project site through modification of regime and/or loss or disruption of ecological function. The project specific activities of altering the natural drainage regimes or moderating natural flows of streams and wetlands during mining operations may also cause increased flows causing more permanent flooding of wetlands. Alternatively, the alteration of natural drainage regimes may cause reduced groundwater and overland flows, which may cause the opposite effect by reducing the hydrologic function of on-site wetlands. It should be noted that this wetland has been degraded by domestic animal grazing (cattle, donkey) and has diminished functional value. Sediment and erosion control measures would be implemented to ensure that increased flows do not negatively inundate on-site and nearby wetlands. Additionally, the capture of normal stormwater and construction runoff and subsequent treatment and discharge as required by NCDEQ DEMLR under the General Permit (No. NCG020000) for Mining Activities would also ensure the reduction of hydrologic regimes would not negatively affect on-site and nearby wetlands. Impacts to wetlands within the project are expected to be minimal and temporary. The project proposes only one wetland impact, consisting of 0.14 acre of permanent impact to Wetland 9. The discharge of fill material for a waste rock area will permanently affect this wetland; however, the applicant is proposing a 2:1 mitigation ratio for this impact, which would be a 0.5 acre wetland credit. The mitigation proposed for this impact allows for a no net loss of wetlands and effectively mitigates for an almost 30% larger wetland area. Therefore, the overall impact to this wetland is negligible.

See Table 16 Table 16. Potential Imaacts on Human Use Characteristics Discussion: Municipal and private water supplies: Municipal water does not serve the area or the project site. Wells are the primary source of drinking water and other water needs in the area. The proposed project is expected to need approximately 600-800 gallons per minute and will be supplemented by collecting on-site stormwater runoff for a closed circuit recirculating water supply, before being treated and discharged. If the project demands water in excess of what is naturally produced on site, then a high capacity well or stream withdraw permit may be needed (and appropriately permitted, as applicable). The applicant's environmental consultant has installed five groundwater monitoring wells, four groundwater observation wells, and one groundwater pumping wells to facilitate periodic groundwater level, water quality monitoring, and aquifer testing throughout the site. Measurements have been taken monthly starting July 2018 and will be measured through July 2019. The purpose of these studies is to determine if the mining activities will have an effect on the area's aquifer and groundwater supply. The results will be shared once complete. At this time, groundwater supply in the surrounding area is not expected to increase or decrease due to activities at the proposed project site.

Page 54 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Recreational and commercial fisheries: The on-site stream channels are not part of or any close proximity to any recreation or commercial fishery. Therefore, the project would not affect these resources/uses. Water -related recreation: Activities taking place at the proposed project site would not increase or decrease waterborne recreation ion, or in the vicinity of the project. The stream channels that would be impacted by the project are not used for water related recreation. Therefore, the project would not affect these resources/uses. Aesthetics: The project area is in a rural residential and rural agricultural area. The project may have short term, minor effects to the aesthetics of the area. However, the North Carolina Division of Mining requires a minimum of 25 feet of natural (vegetated) screening between the boundary and mining operations. Additionally, Gaston County requires 300 -foot setback buffers from the boundary as well. The 25 -foot natural screening buffer will be left as is (i.e. not cleared and remaining in its current state pre -mining operations) and a berm will be built from stripping material between the 25- and 300 -foot buffer areas. The berm will serve as a visual screen and the natural 25 -foot vegetated natural buffer will act as an aesthetic buffer as well. Therefore, the aesthetics of the area will only experience minor and short term effects. 6.5 Pre -testing evaluation (Subpart G, 40 CFR 230.60): The following has been considered in evaluating the biological availability of possible contaminants in dredged or fill material. See Table 17: Table 17. Possible Contaminants in Dredaed/Fill Material Physical characteristics Hydrography in relation to known or anticipated sources of contaminants Results from previous testing of the material or similar material in the vicinity of the project Known, significant sources of persistent pesticides from land runoff or percolation Spill records for petroleum products or designated (Section 331 of CWA) hazardous substances Other public records or significant introduction of contaminants from industries, municipalities, or other sources Known existence of substantial material deposits of substances which could be released in harmful quantities to the aquatic environment by man -induced discharge activities Discussion: It has been determined that testing is not required because the discharge and extraction sites are adjacent, subject to the same sources of contaminants and Page 55 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) have substantially similar materials. Although the discharge material may be a carrier of contaminants, it is not likely to degrade the disposal site. The applicant has engaged a consultant to provide a sampling and analysis plan that will identify and assess potential contaminants associated with the proposed waste rock disposal areas. Testing is currently underway and results will be provided once complete. At that time if contaminants are determined present, then a mitigation plan will be developed, as necessary. The applicant's environmental consultant also conducted research at the NC Division of Mining office to determine if historical, similar mining sites provided substantive evidence that mines of this type were known to have contaminants. Of two sites researched, neither were known be sources of harmful contaminants. 6.6 Evaluation and testing (Subpart G, 40 CFR 230-61): Discussion: N/A 6.7 Actions to minimize adverse impacts (Subpart H). The following actions, as appropriate, have been taken through application of 40 CFR 230.70-230.77 to ensure minimal adverse effects of the proposed discharge. See Table 18: Table 18_ Actions to Ensure Adverse Effects are Minimized Actions concerning the location of the discharge x Actions concerning the material to be discharged x Actions controlling the material after discharge x Actions affecting the method of dispersion x Actions affecting plant and animal populations x Actions affecting human use x Discussion: Actions concerning the location of the discharges: The discharge of fill material has been designed to minimize or prevent the creation of standing bodies of water and provide for normal flow of water, the extent of any plume, and the disruption of periodic water inundation patterns. The material to be discharged would be similar to the existing site substrate but mixed due to the nature of mining. Actions concerning the material to be discharged: The fill material would consist of waste rock and top soil taken from onsite. The fill material would be free of toxic pollutants in toxic amounts. The rock is not expected to contain natural constituents that are toxic or could become toxic and/or bioavailable as a result of the discharge. This would ensure that physiochemical conditions are maintained and the potency and availability of pollutants are reduced. Page 56 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Actions controlling the material after discharge: The fill material would be stabilized after discharge to prevent erosion and slumping by using grade controls; sediment containment fencing; cover seeding; sediment basins; and storm water controls. Actions affecting the method of dispersion: Sediment fencing, sediment basins, and dewatering structures would aid in minimizing the potential of the fill material to disperse. Actions affecting plant and animal populations: Fill material would be placed in disposal sites that would contain no flow or be dewatered prior to the placement of fill and aquatic life movement would be negligible. The activities in waters of the U.S. are not expected to create habitat conducive to the development of undesirable predators or species which have a competitive edge ecologically over indigenous plants or animals. The project site is similar to surrounding landscapes and does not represent a rare landscape or contain any unique landscape elements in general; thus, the surrounding area is representative of similar plant and animal populations on the project site and the activities in waters of the U.S. would have minimal effects to plant and animal populations relative to their presence in the surrounding area. Actions affecting human use: The proposed project site is located outside of public and private water intakes. Procedures for discharging fill material would minimize the disturbance of aesthetic features of the aquatic resources onsite. The activities in waters of the U.S. are internal to the project site and are generally not visible, accessible, or considered aesthetically pleasing to humans. 6.8 Factual Determinations (Subpart B, 40 CFR 230.11). The following determinations are made based on the applicable information above, including actions to minimize effects and consideration for contaminants. See Table 19: Table 19. Factual Determinations of Potential Impacts Page 57 of 85 Minor Minor No Negligible Effect Effect Site N/A Effect Effect (Short (Long Major Effect Term) Term) Physical substrate x Water circulation, fluctuation and salinity x Suspended particulates/turbidity x Contaminants x Aquatic ecosystem and organisms X Page 57 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Discussion: Physical substrate: A stream crossing will be installed directly in Perennial Stream 2. The substrate in this area would be buried and aquatic functions eliminated. The discharge would consist of a RCP that is yet to be designed. All work will be conducted in the dry. The pit material and waste rock would be placed directly in 4,547.5 linear feet of onsite intermittent stream and 1,208 linear feet of perennial stream. The substrate in these areas would be buried and aquatic functions eliminated. The discharge would consist of onsite pit material and waste rock and would not include any trash, debris, car bodies, asphalt, etc. The fill material would also be free of toxic pollutants in toxic amounts. Proper sediment and erosion control measures would be installed prior to and during construction to ensure that the substrate of all remaining waters on the property would not be change or affected. Water circulation, fluctuation, and salinity: The proposed discharged dredge and fill material is not expected to modify current downstream water circulation patterns by obstructing flow, changing direction or velocity of water, or changing velocity or flow and circulation. This project is not anticipated to have more than a minimal effect on the downstream hydrologic regimes associated with naturally occurring hydro -period fluctuations. On-site storm water management facilities would ensure that downstream hydro periods are not altered beyond minimal levels. Because this project is located inland and away from tidally influenced waters and wetlands, no modification to the salinity of on-site or adjacent waters is expected. Suspended particulates/turbidity: During construction activities on the site, there may be a minimal increase in suspended particulates that may lead to increased turbidity downstream. However, the increase would be minimal and temporary due to the installation and maintenance of proper sediment and erosion control measures before and during mine operation. Contaminants: The proposed discharge of dredge and fill material should not cause increased chemical contamination levels within the aquatic ecosystem.

Page 58 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Specifically, changes in clarity, color, odor, and taste of water in addition to possible chemical contamination would be minimal. All discharges of dredge and fill material would be controlled with a sediment and erosion control plan. The pit material and waste rock that would be discharged would be taken from on-site areas. The material would be clear and free of chemical contamination. Proposed disposal sites: The discharges for the impacts associated with the waste rock areas would be controlled and confined to fill areas and constructed in the dry to the maximum extent possible. All fill placed would be contained using sediment and erosion control measures. Some minor and short term suspended sediment plumes and related turbidity in adjacent waters may occur due to sediment movement as a result of the construction during heavy rainfall events. Cumulative effects on the aquatic ecosystem: See Section 9.0. Secondary effects on the aquatic ecosystem: See Section 9.0. 6.9 Findings of compliance or non-compliance with the restrictions on discharges (40 CFR 230.10(a -d) and 230.12). Based on the information above, including the factual determinations, the proposed discharge has been evaluated to determine whether any of the restrictions on discharge would occur. See Table 20: Table 20. Compliance with Restrictions on Discharge Subject Yes No 1.

To the extent appropriate, the public interest review below also includes consideration of additional policies as described in 33 CFR 320.4(b) through (r). The benefits which reasonably may be expected to accrue from the proposal are balanced against its reasonably foreseeable detriments. 7.1 All public interest factors have been reviewed and those that are relevant to the proposal are considered and discussed in additional detail.

Economics: The project would provide an overall benefit to the local economy. The project would provide work for local labor forces in the Charlotte/Gastonia metro area, including Cherryville and northwest Gaston County. It would also provide a competitive source of lithium which would likely keep lithium prices in the domestic market area relatively low. According to the applicant, the appropriate economic evaluations have been completed and the project as proposed is economically viable. Aesthetics: The project area is in a rural residential and rural agricultural area and the project may have short term, minor effects to the aesthetics of the area.

Economics: The project would provide an overall benefit to the local economy. The project would provide work for local labor forces in the Charlotte/Gastonia metro area, including Cherryville and northwest Gaston County. It would also provide a competitive source of lithium which would likely keep lithium prices in the domestic market area relatively low. According to the applicant, the appropriate economic evaluations have been completed and the project as proposed is economically viable. Aesthetics: The project area is in a rural residential and rural agricultural area and the project may have short term, minor effects to the aesthetics of the area. Page 61 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) However, there will be 300 -foot setback buffers from surrounding properties. Additionally, rezoning applications will be made as necessary to observe local rezoning regulations. Through the 300 -foot buffer setback and land use rezoning, the project is not expected to diminish the aesthetic value of the area or cause disharmony from an aerial or neighboring view. General Environmental Concerns: All applicable federal, state, and local laws and regulations would be observed, and construction would not commence before applicable permit approvals. The proposed project would occur within the realm of those constraints, which are put in place to make sure minimal effects occur. Additionally, mitigation for stream and wetland impacts ensures a no net loss of aquatic resources. A Stormwater Pollution Prevention Plan under the General Permit (No. NCG020000) for Mining Activities would also ensure that the proposed project would not negatively affect remaining on-site and downstream streams and wetlands. Wetlands: The wetlands found on the project site are typical for the physiographic region. Sediment and erosion control measures would be implemented to ensure that increased flows do not negatively inundate on-site and nearby wetlands. Additionally, the capture of normal stormwater and construction runoff and subsequent treatment and discharge as required by NCDEQ DEMLR under the General Permit (No. NCG020000) for Mining Activities would also ensure the reduction of hydrologic regimes would not negatively affect on-site and nearby wetlands. Finally, as compensatory mitigation will be required for wetlands impact, there is effectively no net loss of wetlands with activities association with this project. Impacts to wetlands within the project are expected to be minimal and temporary. Fish and Wildlife Values: The terrestrial and aquatic species found on the project site are typical for the physiographic region. In order to construct the proposed facility, the vegetation in this area would be removed with typical mechanized land clearing equipment. This vegetation in the form of wooded buffers and transitional/fallow fields provides habitat for small mammals, reptiles, birds, insects, etc. A majority of these species can and would probably relocate to surrounding/adjacent habitats once construction activities begin on the site. Flood Hazards: Due to the relatively small sizes of the watersheds per each impact area (i.e. all headwater catchment areas), the proposed activities within the project boundary are not expected to increase or decrease the natural rate of flooding at the site or downstream. Therefore, no effects are anticipated. Floodplain Values: There is a mapped floodplain and floodway on Beaverdam and Little Beaverdam Creeks that bisect the project site. However, all site Page 62 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) development would take place outside of the designated 100 -year floodplain and floodway. Therefore, no effects are anticipated. Land Use: The proposed project would be in compliance with local zoning regulations and ordinances and/or rezoning would be applicable. Therefore, no effect is anticipated. Water Supply and Conservation: The proposed project would utilize existing water sources but it is not expected to substantially affect the availability of water in this area. Private water supply in the surrounding area is not expected to increase or decrease due to activities at the proposed project site. Private water supply servicing the project is expected to range about 600-800 gallons per minute and will be supplemented by collecting on-site stormwater runoff for a closed circuit recirculating water supply, before being treated and discharged. If the project demands water in excess of what is natural produced on site, then a high capacity well or stream withdraw permit may be needed (and appropriately permitted, as applicable). Water Quality: The proposed discharge of dredge and fill material should not cause increased chemical contamination levels within the aquatic ecosystem. Specifically, changes in clarity, color, odor, and taste of water in addition to possible chemical contamination would be minimized by the applicant's storm water management and sediment and erosion control plan. The proposed fill material would consist of clean fill material originating from on site from the adjacent areas to be mined. The fill material used on-site would be clear and free of chemical contamination. The applicant's environmental consultant has installed five groundwater monitoring wells, four groundwater observation wells, and one groundwater pumping well to facilitate baseline monitoring. Energy Needs: Rutherford Electric Membership Corporation (EMC), has an easement within the project boundary. The applicant and Rutherford EMC are coordinating a substation install to occur within the concentrator plant site. From this interface point, all electricity needs would be provided to the site. As the easement for the utility in place, additional energy needs for the area were expected. Therefore, no impacts to energy needs in the area are anticipated. The easement and subsequent aerial transmission line will not cause any impacts to jurisdictional features. Safety: The proposed project would be designed and operated in accordance with federal, state, local, and MSHA laws and regulations that address issues of public safety. Therefore, the proposed activity is not expected to affect public safety. Page 63 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) Food and Fiber Production: The project site is currently a mix of forestry, rural residential, and agricultural land uses. Development of the proposed project would result in the conversion of agricultural land and forestry land to a commercial mining operation. However, agricultural lands form only a small part of the project area. There are extensive agricultural lands available in Gaston County. Therefore, the Corps believe the project would have a negligible on food and fiber production. Needs and Welfare of the Public: The proposed project would positively address the needs and welfare of the public by providing a competitive source of lithium to the domestic market. Also, new jobs at the mine would boost the Charlotte/Gastonia metro area economy, including Cherryville and northwest Gaston County. Mineral Needs: The proposed project would positively address the need for a domestic source of lithium by targeting the extraction of mineralized spodumene. The mineral needs for this project is the identified pit shell areas where mineralized spodumene has been indicated. Consideration of property ownership: The properties within the project boundary are 78% controlled by the applicant at the time of this submission. Negotiations are currently ongoing for control of the remaining 22%. The applicant is confident that 100% control will occur in 2019. 7.1.1 Climate Change. The proposed activities within the Corps federal control and responsibility likely will result in a negligible release of greenhouse gases into the atmosphere when compared to global greenhouse gas emissions. Greenhouse gas emissions have been shown to contribute to climate change. Aquatic resources can be sources and/or sinks of greenhouse gases. For instance, some aquatic resources sequester carbon dioxide whereas others release methane; therefore, authorized impacts to aquatic resources can result in either an increase or decrease in atmospheric greenhouse gas. These impacts are considered de minimis and are negated through compensatory mitigation. Greenhouse gas emissions associated with the Corps' federal action may also occur from the combustion of fossil fuels associated with the operation of construction equipment, increases in traffic, etc. The Corps has no authority to regulate emissions that result from the combustion of fossil fuels. These are subject to federal regulations under the Clean Air Act and/or the Corporate Average Fuel Economy (CAFE) Program. Greenhouse gas emissions from the Corps action have been weighed against national goals of energy independence, national security, and economic development and determined not contrary to the public interest. Page 64 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 7.2 The relative extent of the public and private need for the proposed structure or work: The proposed project serves the private need of the applicant to create a profitable business by entering the domestic lithium market, but also serves the public need for a domestic source of lithium to insulate domestic prices in a global market. 7.3 If there are unresolved conflicts as to resource use, explain how the practicability of using reasonable alternative locations and methods to accomplish the objective of the proposed structure or work was considered. Discussion: There are no unresolved conflicts identified as to resource use. 7.4 The extent and permanence of the beneficial and/or detrimental effects that the proposed work is likely to have on the public and private use to which the area is suited: Detrimental effects are expected to be minimal and temporary. Beneficial effects are expected to be minimal and temporary. Based on the analysis above there would be minimal/negligible detrimental effects to aquatic/other biological/terrestrial resources on the site when compared to the beneficial effects on the human uses/characteristics and public interest. 8.0 Mitigation(33 CFR 320.4(r), 33 CFR Part 332, 40 CFR 230.70-77, 40 CFR 1508.20 and 40 CFR 1502.14) 8.1 Avoidance and Minimization: When evaluating a proposal including regulated activities in waters of the United States, consideration must be given to avoiding and minimizing effects to those waters. Avoidance and minimization measures are described above in Sections 1 and 3. Were any other mitigative actions including project modifications discussed with the applicant implemented to minimize adverse project impacts? (see 33 CFR 320.4(r)(1)(i)) Yes The applicant engaged its environmental consultants to provide the expertise of conducting threatened and endangered species surveys pursuant to Section 7(a)(2) of the Endangered Species Act, conducting a cultural resources survey pursuant to Section 6 of the National Historic Preservation Act, conducting groundwater, aquifer, and water quality monitoring for baseline environmental conditions, and pre-emptive testing of waste rock/tailings material for potential Page 65 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) contaminants. Results of all studies have been or will be provided once completed. 8.2 Is compensatory mitigation required to offset environmental losses resulting from proposed unavoidable impacts to waters of the United States? Yes Provide rationale: As there is over 300 linear feet of stream channel proposed for impacts, compensatory mitigation is required to offset the unavoidable impacts to waters of the U.S. 8.3 Type and location of compensatory mitigation 8.3.1 Is the impact in the service area of an approved mitigation bank? No If yes, does the mitigation bank have appropriate number and resource type of credits available? N/A 8.3.2 Is the impact in the service area of an approved in -lieu fee program? Yes If yes, does the in -lieu fee program have the appropriate number and resource type of credits available? Yes 8.3.3 Selected compensatory mitigation type/location(s).

No If yes, provide rationale for the deviation, including the likelihood for ecological success and sustainability, location of the compensation site relative to the impact site and their significance within the watershed, and/or the costs of the compensatory mitigation project (see 33 CFR §332.3(a)(1)): N/A 8.4 Amount of compensatory mitigation: Page 66 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) The North Carolina Stream and Wetland Assessment Methodologies (NCSAM and NCWAM) were utilized to determine functional scores for features that would be impacted. These functional scores were then assigned ratios that would determine amount of mitigation required. The following mitigation ratios are proposed: NCSAM • 2:1 for perennial channels that scored `High' (1,263 linear feet for 2,526 credits); • 1:1 for intermittent channels that scored `High" (1,880 linear feet for 1,880 credits); • 0.5:1 for intermittent channels that scored `Medium' (2,279 linear feet for 1,139.5 credits); and • 0:1 for intermittent channels that scored `Low" (two reaches of stream that are degraded due to agricultural and husbandry practices (388.5 linear feet of stream for 0 credits). NCWAM • 2:1 for wetlands that scores `High' (0.14 acre for 0.5 acre of wetland). Rationale for required compensatory mitigation amount: The current project impacts are beyond any threshold that would be considered individually minimal. Various compensatory mitigation ratios are proposed. See Table 23 for a summary of proposed mitigation rationale. The NCSAM and NCWAM data forms and the NCDWQ Stream Identification Forms are attached to this submittal. Table 23. Proposed mitigation ratios.

As an alternative, the district engineer may determine that it would be more appropriate to address any of the items described in (c)(2) through (c)(14) as permit conditions, instead of components of a compensatory mitigation plan. Presence of sufficient information related to each of these requirements in the applicant's mitigation plan is indicated by "Yes" in Table 21. "No" indicates absence or insufficient information in the plan, in which case, additional rationale must be provided below on how these requirements will be addressed through special conditions or why a special condition is not required: Table 24. Perm itee-Responsible Mitigation Plan Requirements Requirement Yes No Objectives Site selection Site protection instrument Baseline information Determination of credits Mitigation work plan Maintenance plan Performance standards Monitoring requirements Long-term management plan Adaptive management plan Financial assurances Other Page 68 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) For any "No", provide rationale on how the subject component(s) of the compentatory mitigation plan will be addressed as special conditions or why no special conditions are required: Provide discussion here 9.0 Consideration of Cumulative Impacts (40 CFR 230.11(g) and 40 CFR 1508.7, RGL 84-9) Cumulative impact is the impact on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (Federal or non -Federal) or person undertakes such other actions. Cumulative impacts can result from individually minor direct and indirect but collectively significant actions taking place over a period of time. A cumulative effects assessment should consider how the direct and indirect environmental effects caused by the proposed activity requiring DA authorization (i.e., the incremental impact of the action) contribute to cumulative effects, and whether that incremental contribution is significant or not. . 9.1 Identify/describe the direct and indirect effects caused by the proposed activity: The direct effects of the proposed activity in waters would include the loss of jurisdictional waters (as specified in Section 1.3) and their associated aquatic resource functions. The proposed activities also have the potential to result in indirect effects to waters including excess sedimentation in downstream waters, disruption and/or killing of aquatic life in the direct vicinity of the project area, and a potential increase in downstream flows. These indirect effects are expected to be minimal due to the applicant's proposed avoidance, minimization, and mitigation measures. Additionally, indirect effects would be further reduced through the implementation of best management practices required by state, local, and federal ordinances and regulations. Another potential indirect effect would be the construction of a chemical conversion plant associated with the proposed project. However, the proposed project would occur regardless of whether a conversation plant would be constructed or not. Additionally, the future plans, if any, for this facility are unknown; therefore, potential impacts associated with it are unknown and not quantifiable at this time. 9.2 The geographic scope for the cumulative effects assessment is: The geographic area for this assessment is the South Fork Catawba sub -basin which is part of the Santee (Catawba) River Basin (Figure 25). This watershed contains the proposed project area and the areas that would potentially be affected by the proposed project. The general South Fork Catawba sub -basin watershed characteristics and land uses are summarized in Table 25.

The date May 11, 2006 was chosen because no data is available in the Corps ORM2 for cumulative impacts prior to that date due to database migration issues. Information for expected future growth and development in the geographic area was gathered from an urban growth study that was conducted by The University of North Carolina at Charlotte for the Charlotte metropolitan area. 9.4 Describe the affected environment: The U.S. Geological Survey (USGS) National Hydrography Dataset (NHD) provides digital geospatial datasets to the public that map a network of surface waters and catchments of the U.S., which provides crude estimates of the type and quantity of various types of aquatic resources within the watershed (Table 26 and Table 27). The U.S. Fish and Wildlife Service also provide estimates of the quantity and types of aquatic resources as part of their publically available National Wetland Inventory (NWI) dataset (Table 28). These estimates are usually made using remote sensing methods which are known to be inaccurate and not representative of what would be considered jurisdictional under the Corps regulatory program (normally underestimated). According to a Ph.D. Dissertation completed by Thomas P. Colson of North Carolina State University in 2005, the NHD 1:24,000 dataset only identified 65% of streams mapped in the field using the North Carolina Division of Water Quality stream identification methods.14 Table 26.

According to the ORM2 database, 171,930 linear feet (Table 29) were impacted in some manner from May 11, 2006 to July 27, 2017. The authorized linear foot measure in the ORM2 database account for stream impacts both temporary and permanent in nature. This accounts for a rate of 83 linear foot of impact per day in the South Fork Catawba sub -basin. The total stream impacts during this time period represents 0.76% of the total streams currently mapped by the USGS within the South Fork Catawba sub -basin. It is expected that many more linear feet of stream subject to the Corps regulatory authority are present in the South Fork Catawba sub -basin due to the inaccuracies in the NHD dataset. Approximately 19,127 acres of wetlands have been identified as part of the U.S. Fish and Wildlife National Wetland Inventory within the South Fork Catawba sub - basin. According to the ORM2 database, 48 acres (Table 29) were impacted in some manner from May 11, 2006 to July 27, 2017. The authorized fill measure in the ORM2 database accounts for the area of filled for wetland and stream, both temporary and permanent in nature. Assuming these were all wetland impacts, this accounts for a rate of 0.01 acre of wetland impact per day in the South Fork Catawba sub -basin. The total potential wetland impacts during this time period Page 73 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) represents 0.2% of the total wetlands currently mapped by the U.S. Fish and Wildlife Service within the South Fork Catawba sub -basin. It is expected that many more acres of wetlands subject to the Corps regulatory authority are present in the South Fork Catawba sub -basin due to the inaccuracies in the NWI dataset. Table 29.

However, the mine would be located near the northern boundary of Gaston County and would utilize supplies and labor from a large part of Mecklenburg and Gaston County. Therefore, the development of Mecklenburg County and surrounding area is an appropriate surrogate when looking at the likely development trends in this part of Gaston County. Figure 28 to Figure 30 show the relative rate of development that has occurred in this area since 1985. Mecklenburg County's population increased 117 percent between 1976 and 2006 according to an analysis on urban growth conducted in 2008 by the Urban Institute at the University of North Carolina at Charlotte. Mecklenburg County began to rapidly develop in the mid-1980s and has steadily increased to present day (Figure 26 to Figure 28). This growth slowed for a period during an economic recession that generally began in 2007 and ended in 2011. The rate of growth in Mecklenburg County between 2015 and 2016 was 1.9% according to a U.S. Census Bureau report released on May 25, 2017. This rapid development of Mecklenburg has spilled over into adjacent communities such as Gaston County and is forecasted to continue into the foreseeable future (Figure 29 and Figure 30).

Besides Corps authorized projects, other activities include residential, commercial, institutional and recreational development on uplands, as well as numerous infrastructure and facility maintenance projects that do not require Corps authorization or notification. Resulting natural resource changes and stresses include loss of wildlife habitat, increases in storm water flows, and decreases in overall water quality. Aquatic resources are also being affected by the increase in impervious surfaces, and the application of numerous herbicides, pesticides, and fertilizers associated with residential, commercial, and institutional developments and roadway construction/expansion. Additional issues of concern in this watershed are the decrease in floodwater retention capabilities, increase in storm water flows and decreased water quality, specifically nitrogen and phosphorus inputs from point sources, especially municipal wastewater, and non -point sources such as urban storm water runoff and rural agricultural runoff. 9.6 Discuss any mitigation to avoid, minimize or compensate for cumulative effects: During the period between May 11, 2006 and July 27, 2017, the Corps required approximately 11 acres and 24,503 linear feet of compensatory wetland and stream mitigation, respectively, in the form of restoration, preservation, and/or enhancement (Table 29). 9.7 Conclusions regarding cumulative impacts: When considering the overall impacts that will result from the proposed activity, in relation to the overall impacts from past, present, and reasonably foreseeable future activities, the incremental contribution of the proposed activity to cumulative impacts in the area described in section 9.2, are not considered to be significant. Compensatory mitigation Select will or will not be required to help offset the impacts to eliminate or minimize the proposed activity's incremental contribution to cumulative effects within the geographic area described in Section 9.2. Mitigation required for the proposed activity is discussed in Section 8.0. 10.0 Compliance with Other Laws, Policies, and Requirements 10.1 Section 7(a)(2) of the Endangered Species Act (ESA): Refer to Section 2.2 for description of the Corps action area for Section 7. Page 78 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) 10.1.1 Are there listed species or designated critical habitat present or in the vicinity of the Corps' action area? No. The Corps has determined that it has fulfilled its responsibilities under Section 7(a)(2) of the ESA Effect determination (s), including no effect, for all known species/habitat, and basis for determination(s): The applicant's consultant consulted the U.S. Fish and Wildlife (USFWS) Information for Planning and Consultation (IPaC) database and the North Carolina Natural Heritage Program (NCNHP) Data Explorer for a list of federally protected species with potential to occur within and in proximity to the project site. Table 30 summarizes federally listed in both databases that have the potential to be located in proximity to the project site. The IPaC database was last accessed on September 21, 2018 (IPac Resource List, attached) and the NCNHP Data Explorer was last accessed on November 6, 2019 (NCNHDE-7459, attached). The IPaC Resourse list indicated that no known occurrences or critical habitat have been document within the project site. The NCNHP Data Explorer query revealed that no known occurrences of federally protected species have been documented within the project site; however, one historical occurrence (pre -1917) of a federally protected species occurs within a one -mile radius of the project site.

Additional field work has been conducted on the site during two visits each in August, October, and November 2018, including continued observation for habitat and individuals listed in Table 30. None have been identified to date. Three areas that were not accessible during the 2018 surveys will be reviewed in 2019 (Figure 31).

During the 2018 March, April, August, October, and November surveys, no suitable habitat for the bald eagle, bog turtle, Schweinitz's sunflower, or Michaux's sumac were identified and none of these species were observed during the field surveys. However, suitable habitat for the dwarf -flowered heartleaf was identified (Figure 31) during the March field efforts and subsequently surveyed for the species during the April field efforts. Utilizing topographic and soil survey GIS files, target areas for the dwarf -flowered heartleaf were identified on Pacolet soils on north facing slopes prior to field work. These areas were surveyed in the field and suitable habitat for the species was identified (Figure 11 and Figure 31). The field work was conducted during the appropriate flowering window (March -May) for dwarf -flowered heartleaf and although other species of Hexastylis were observed, no individuals of dwarf - flowered heartleaf were identified. Areas identified as not being suitable for this species were due to a number of factors such as the presence of pine plantations, cattle disturbance, highly modified understory, or timber and agricultural practices with heavy disturbance. These areas were still carefully observed during periodic field work throughout this timeframe for individuals of dwarf -flowered heartleaf and none were identified. The project was also reviewed in accordance with the northern long-eared bat (NLEB) Standard Local Operating Procedures for Endangered Species Page 80 of 85 CE SAW -RG -C (File Number, SAW 2018-01129) (SLOPES) between the USACE, Wilmington District, and the Asheville and Raleigh U.S. Fish and Wildlife Service (Service) Offices, and determined that the project is located outside of the highlighted areas/red 12 -digit HUCs and activities in the project limits do not require prohibited incidental take; as such, this project meets the criteria for the 4(d) rule and any associated take is exempted/excepted. As established in the NLEB SLOPES, this project does not require prohibited intentional take of the NLEB and it meets the criteria for the 4(d) rule. Based on the desktop review of the IPaC and NCNHP Project Report, GIS files, and field reviews, the project will have no effect on the bald eagle, bog turtle, Schweinitz's sunflower, or Michaux's sumac. The project may affect, but is not likely to adversely affect the northern long-eared bat. The suitable habitat identified for the dwarf -flowered heartleaf within the proposed project has been surveyed for the species during the appropriate flowering window — no individuals of the species were observed. The three remaining areas to be reviewed will not be impacted by the proposed project (Figure 31); therefore, the project will have no effect on the dwarf -flowered heartleaf. The results of the additional surveys will still be provided once completed. A letter has been sent to the USFWS by the applicant's environmental consultant; however, a response has yet to be received. 10.1.2 Has another federal agency been identified as the lead agency for complying with Section 7 of the ESA with the Corps designated as a cooperating agency and has that consultation been completed?

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site-specific (e.g., vegetation/species surveys) and project -specific (e.g., magnitude and timing of, proposed activities) information. 4 Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population, even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site-specific and project -specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following: 1. Draw the project location and click CONTINUE. 2. Click DEFINE PROJECT. 3. Log in (if directed to do so). 4. Provide a name and description for your project. 5. Click REQUEST SPECIES LIST. Listed species' and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries). Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction. 1.

Any person or organization who plans or conducts activities that may result in impacts to migratory birds, eagles, and their habitats should follow appropriate regulations and consider implementing appropriate conservation measures, as described below. 1. The Migratory Birds Treaty Act of 1918. 2. The Bald and Golden Eagle Protection Act of 1940. Additional information can be found using the following links: Birds of Conservation Concern http://www.fws.gov/birds/management/managed-species/ birds-of-conservation-concern.php Measures for avoiding and minimizing impacts to birds http://www.fws.gov/birds/management/project-assessment-tools-and-guidance/ conservation-measures.php Nationwide conservation measures for birds http://www.fws.gov/migratorybirds/pdf/management/nationwidestandardconservationmeasures.pdf https://ecos.fws.gov/ipac/location/MRW16CW4MNCFXC25A4ZI14VZVI/resources 3/7 11/6/2018 IPaC: Explore Location THERE ARE NO MIGRATORY BIRDS OF CONSERVATION CONCERN EXPECTED TO OCCUR AT THIS LOCATION. Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 14km grid ceII(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the E -bird Explore Data Tool. �I What does IPaC use to generate the probability of prese rice graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey,, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and haw to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls Within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and https://ecos.fws.gov/ipac/location/MRW16CW4MNCFXC25A4ZI14VZVI/resources 4/7 11/6/2018 IPaC: Explore Location 3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. 040%LS Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving bird Study_ and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cells) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence scare can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Wetlands in the National Wetlands inventory Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District. \1) WETLAND INFORMATION IS NOT AVAILABLE ATTHIS TIME This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or for very large projects that intersect many wetland areas. Try again, or visit the NWI map to view wetlands at this location. Data limitations A" The Service's objeetive of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery, thus, detailed on -the -ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. https://ecos.fws.gov/ipac/location/MRW16CW4MNCFXC25A4ZI14VZVI/resources 6/7 11/6/2018 Data precautions IPaC: Explore Location Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.
