Inspection Requirements for Missouri
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 Missouri. Eligibility, exemptions, local approvals, and project-specific conditions vary, so confirm coverage under the MO-R100000 General Permit 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.
