All NOIs and NOTs must be filed electronically through the myDEQ portal. Paper submissions are rarely accepted.

Inspection Requirements for Arizona

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 Arizona. Eligibility, exemptions, local approvals, and project-specific conditions vary, so confirm coverage under the AZPDES Construction General Permit (CGP) 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

Arid climate waivers may apply. ADEQ focuses heavily on dust control and tracking in the dry season.
