Commission approves industrial rezoning for Heidelberg Materials parcels after residents voice groundwater and traffic concerns

Summary
Dorchester County approved a broad rezoning to industrial for parcels tied to Giant/Heidelberg Materials to regularize long‑standing mining operations; residents urged buffers, groundwater monitoring and restrictive conditions citing private wells, dust and truck traffic.
The Dorchester County Planning Commission voted to rezone roughly 2,386 acres in the Harleyville area from AR (agricultural residential) to I (industrial) to bring long‑standing Giant/Heidelberg Materials operations into a conforming industrial zoning category.
Staff framed the request as an administrative correction following earlier zoning changes that left several long‑operating mining parcels legally nonconforming. Brett Miller, director of land and environmental sustainability for Heidelberg Materials in the Southeast, said the firm has operated in the county for about 80 years and that the request is intended to allow the business to continue as a conforming use; he told the commission there were no present plans to expand operations.
Multiple residents said the rezoning risked damage to private well water, increased heavy truck traffic, dust and air particulates, and encroachment on rural residential areas. Kim Huff, Amanda and James Faulkner and others urged the commission to impose binding conditions if it approves the change — including enforceable setbacks, groundwater monitoring and limits on permitted uses — because industrial zoning allows a wide range of uses by right. Amanda Faulkner told commissioners she relies on a private well and said the comprehensive plan designates parts of the area for environmental conservation.
John Trulock, Dorchester County’s economic development director, supported the rezoning and said the county does not regulate mining operations — permitting is a state function — so the rezoning corrects an administrative problem and helps preserve a major local employer and property tax base.
Commission discussion focused on compatibility with the comprehensive plan, the practical differences between AR (where mining can be conditional) and industrial (where mining is permitted), and the classification and capacity of local roads for heavy traffic. After discussion the commission approved the rezoning by voice vote.
Why it matters: The vote regularizes zoning for a major local employer and tax payer but raises questions about long‑term compatibility with nearby residential properties, private well protection, and whether binding local conditions are sufficient to address environmental and traffic concerns.
