The Corps evaluates this application and decides whether to issue, conditionally issue, or deny the proposed work pursuant to applicable procedures of the following Statutory Authorities:

Section 404 of the Clean Water Act (33 U.S.C. 1344)



Location Description:

Project Area (acres): 917

Nearest Town: Cherryville, NC

Nearest Waterway: Beaverdam Creek

River Basin: South Fork Catawba

Latitude and Longitude: 35.387869, -81.286758

Existing Site Conditions

The proposed Piedmont Lithium project is located in the piedmont physiographic region of North Carolina and encompasses 971 acres of land in Gaston County (reference Figure 1- Site Location in the attached plans). The project area is approximately 67% forested land, consisting of mixed medium 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, 16 wetlands, and four ponds/impoundments.

Applicant’s Stated Purpose

The purpose of the project is to develop a hard rock lithium mine in the Carolina Tin-Spodumene Belt to extract and refine mineralized spodumene to a high quality lithium bearing spodumene concentrate; which, upon conversion to a battery grade lithium hydroxide, would provide a domestic source of lithium to meet growing demands in the U.S.

Project Description

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 5,810.5 linear feet of stream channel, 0.14 acre of wetlands, and 0.16 acre of open water pond/impoundment. 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 open water pond/impoundment would be impacted by waste rock areas. Approximately 249 linear feet of perennial stream channel and 2,264.5 linear feet of intermittent stream channel would be impacted by pit shell areas. Approximately 178 linear feet of perennial stream channel would be impacted by an internal access road stream crossing and 55 linear feet of perennial channel would be impacted by a storm water BMP.

Avoidance and Minimization

The applicant provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:

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 have been minimized through utilization of the footprint of an existing crossing for an access road. Avoiding disturbance in the FEMA floodplain will prevent impacts to the entirety of 7.62 acres of wetlands and 0.40 acre of wetlands 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 (totaling 27,192 feet, to include Beaverdam and Little Beaverdam Creeks). Indirect impacts to remaining streams will be avoided through the use of 100-foot stream buffers and storm water 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 as described in the Environmental Assessment submitted with the permit application. 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 the Section 404 individual permit application. A Storm Water Pollution Prevention Plan is also being developed and will be submitted upon completion to the North Carolina Department of Environmental Quality Division of Energy, Mineral, and Land Resources under the General Permit (No. NCG020000) for Mining Activities.

Compensatory Mitigation

The applicant offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:

There are no active private mitigation banks within Hydrologic Unit Code (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. The applicant provided supporting documentation from DMS in a letter dated December 21, 2018, 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). The proposed compensatory mitigation ratios are shown in Table 1.

Essential Fish Habitat

Pursuant to the Magnuson-Stevens Fishery Conservation and Management Act, this Public Notice initiates the Essential Fish Habitat (EFH) consultation requirements. The Corps’ initial determination is that the proposed project would not affect EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service.

Cultural Resources

Pursuant to Section 106 of the National Historic Preservation Act of 1966, Appendix C of 33 CFR Part 325, and the 2005 Revised Interim Guidance for Implementing Appendix C, the District Engineer consulted district files and records and the latest published version of the National Register of Historic Places and initially determines that:

Properties ineligible for inclusion in the National Register are present within the Corps’ permit area; there will be no historic properties affected by the proposed work. The Corps subsequently requests concurrence from the SHPO (or THPO).

The District Engineer’s final eligibility and effect determination will be based upon coordination with the SHPO and/or THPO, as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on historic properties within the Corps-indentified permit area.
