Inspection Requirements for North Carolina

Construction projects that disturb one or more acres—or smaller sites that are part of a larger common plan—commonly require stormwater permit coverage in North Carolina. Eligibility, exemptions, local approvals, and project-specific conditions vary, so confirm coverage under the NCG01 Construction General Permit before construction begins.

Operational Insight

This schedule combines recurring and event-driven duties. Record rainfall or discharge events independently from the weekly calendar and document why each event did or did not trigger an inspection.

Specific State Nuance

NC uses a 1.0 inch rain trigger for some inspections, but weekly checks are standard. E&SC Plan must be approved locally.
