Permitting authority

Henderson County Department of Public Health — Environmental Health, On-Site Wastewater Program

Henderson County Environmental Health: 828-694-6060; 1200 Spartanburg Highway, Suite 100, Hendersonville, NC 28792.

North Carolina state and local framework

The N.C. Division of Public Health On-Site Water Protection Branch provides statewide regulatory oversight and technical guidance for subsurface onsite wastewater systems, while local health departments carry out county permitting and inspection functions. NCDHHS directs homeowners to the local health department for septic questions, permits, and inspections.

Zoning approval precedes Environmental Health permitting

Henderson County instructs applicants for new construction, additions or alterations, and change-of-use projects to obtain the applicable zoning permit before Environmental Health can issue the septic approval.

Site evaluation factors

The Environmental Health Specialist evaluates topography and landscape position, soil characteristics, soil wetness, soil depth, restrictive horizons, and available space before deciding whether the lot can support the proposed onsite system.

Construction Authorization and final approval

After an acceptable evaluation, the county issues the Improvement Permit and Construction Authorization. The installed system must then be inspected; if approved, the county issues the Operation Permit.

Five-year septic permit expiration

Henderson County states that septic permits expire five years after issuance and cannot be renewed or extended. Its Existing System Approval expires one year after issuance.

Permit required for major component replacement

The county requires a permit when a major system component is replaced or relocated, such as tank replacement or drainfield relocation, expansion, or replacement. It distinguishes these activities from specified routine maintenance that does not require a permit.
