Chapter 2 Haile Gold Mine EIS Project Description and Alternatives 2. PROJECT DESCRIPTION AND ALTERNATIVES 2.1 Introduction This chapter begins with a summary description of the Haile Gold Mine Project proposed by the Applicant. The chapter also discusses connected actions (infrastructure actions needed to support the Project that are not part of Haile’s DA permit application) and the identification and selection process for alternatives to the Applicant’s proposed Project. The alternatives analysis was in part guided by comments received from the public, agencies, and tribes during scoping; and these comments are summarized in the chapter. The chapter also describes the No Action Alternative. 2.1.1 Project Description A detailed description of the Applicant’s proposed Project is necessary to perform a comprehensive environmental analysis. The project description should define the geographic Project area, the layout of facilities in the proposed Project area, and the facilities and operations to be conducted in the Project area. It should discuss the construction sequence for the Project; the construction schedule; labor force requirements; and any regulated air, water, or waste emissions that would occur routinely or that could occur as a result of a disruption in routine project operations. Upon completion of mining operations, a mine closure and reclamation plan also should be included. As part of mine permitting, financial assurance would be required pursuant to the South Carolina State Mining Act (R-89-200). The Applicant’s revised DA permit application (dated August 15, 2012) and supporting documents form the basis for the description of the proposed Project. This chapter contains a summary description of the Applicant’s proposed Project (see Section 2.2); the detailed Project description is in Appendix A. 2.1.2 Identification and Evaluation of Project Alternatives To comply with NEPA regulations, the EIS must identify and evaluate a range of reasonable alternatives to the proposed Project. In addition to meeting the requirements of NEPA, the evaluation of alternatives provides the basis for the USACE to make specific findings under Section 404(b)(1) of the CWA. The alternatives evaluation must comply with the following regulations and guidelines. The National Environmental Policy Act – To comply with NEPA, regulations developed by the CEQ and the USACE require a detailed analysis of reasonable alternatives to the proposed project and their associated potential environmental consequences so that their comparative merits may be considered by agency decision makers (40 CFR 1502.14[b]). The alternatives evaluation must include the applicant’s proposed project, the no action alternative, and a range of other potential reasonable alternatives to the proposed project. The range of potential reasonable alternatives that should be considered includes alternative sites, alternative project configurations, alternative technologies, and alternative project sizes. The Section 404(b)(1) Guidelines – In addition to meeting the requirements of NEPA, the USACE’s regulations implementing the 404(b)(1) guidelines dictate that the USACE may not issue a DA permit without making a finding that no practicable alternative to the proposed project exists that would have less adverse impact on the aquatic environment (Waters of the U.S.), so long as the alternative does not have other significant adverse environmental consequences. This regulatory finding must be supported by an alternatives analysis. A USACE-prepared EIS involving a DA permit application should be thorough enough to determine compliance with NEPA and the 404(b)(1) guidelines. These regulations use different criteria for the Final EIS 2-1 July 2014 Chapter 2 Haile Gold Mine EIS Project Description and Alternatives types of alternatives that should be considered. NEPA considers “reasonable” alternatives, and the 404(b)(1) guidelines consider “practicable” alternatives. Reasonable alternatives include those that are practical or feasible from a technical and economic standpoint and using common sense, rather than simply desirable from the standpoint of the applicant (46 Federal Register [FR] 18026). An alternative is practicable if it is available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes. If it is otherwise a practicable alternative, an area not presently owned by the applicant which could reasonably be obtained, utilized, expanded, or managed in order to fulfill the basic purpose of the proposed activity may be considered (40 CFR 230.10). As noted in Chapter 1, the regulations further require that the USACE alternatives analysis identifies the least environmentally damaging practicable alternative (LEDPA). After a full range of alternatives has been identified and evaluated, the No Action Alternative, the Applicant’s Proposed Project, and the Modified Project Alternative (i.e., reasonable alternative) will be moved forward and evaluated in detail in the EIS (40 CFR 1502.14[a]). The USACE has completed an identification and evaluation of alternatives for the proposed Haile Gold Mine Project and has identified the alternatives to be evaluated in detail in the EIS. The alternatives analysis conducted by the USACE and described in this report complies with NEPA and provides the basis for the USACE to make the required findings under the 404(b)(1) guidelines. Section 401 Water Quality Certification – The SCDHEC reviews applications for 401 Water Quality Certification. This certification is required for projects requesting a federal permit for activities that, during construction or operations, may result in any discharge to Waters of the U.S. The SCDHEC must address and consider whether there are feasible alternatives to an activity proposed in an application. In accordance with R. 61-101, Water Quality Certification, an application for 401 Water Quality Certification will be denied if a feasible alternative to the activity would reduce adverse consequences on water quality and classified uses. The SCDHEC will use the alternatives analysis described in this EIS to address and consider whether there are feasible alternatives to the proposed Project. 2.2 Description of Applicant’s Proposed Project 2.2.1 Project Site The proposed Haile Gold Mine Project is located in north-central South Carolina, 3 miles northeast of the town of Kershaw in southern Lancaster County (Figure 1-1). The proposed Project boundary includes a total of 4,552 acres, of which approximately 2,612 acres1 would be used for Project features (Figure 2-1). The Project area includes the land inside of the Project boundary, with the exception of two land parcels that are not owned by Haile, as shown in Figure 2-1. Although the site was previously mined for gold and other materials, there is no active mining at present. The site is currently undergoing post-closure monitoring for the former mine workings and has no other ongoing commercial, industrial, or urban activities. 1 The area estimated for Project features does not include the area of a disturbance buffer around the design footprint of each mine component.
