Inspection Requirements for Arkansas
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 Arkansas. Eligibility, exemptions, local approvals, and project-specific conditions vary, so confirm coverage under the NPDES General Permit ARR150000 before construction begins.
Operational Insight
A 14-day schedule may be paired with an event-driven inspection requirement. Track both the recurring deadline and qualifying weather events so one schedule does not obscure the other.
Specific State Nuance
Rain trigger is strictly 0.25 inches. A mailbox containing the SWPPP is required on-site if no trailer exists.
