Gold was first discovered in Lancaster County, South Carolina in the 1820s. In 2007 Romarco Minerals acquired the property and began the process of planning, designing and permitting a modern mine at this historic location. ERC provided water resource and environmental consulting services through feasibility, permitting and final design. Environmental work included baseline wetland delineations, habitat functional assessments and impact assessments. Water resource work included climate evaluations, hydrologic and hydraulic assessments, water balance modeling, water supply assessments, spillway design and erosion control. ERC was particularly instrumental throughout the permitting process given our technical and regulatory expertise. We worked with the Corps and their third-party contractor during the EIS process and helped secure permitting which has led to operations of what will become the largest gold mine in the eastern US.
