The answer

None found

We found no state level preparer credential for Arizona. On what we verified, an operator may adopt the plan without a credentialed signature. Local ordinances can still be stricter.

The named Qualified Person role is self-attested. A.R.S. 32-144 is a conditional practice-act citation and does not make plan preparation a licensed activity.

No permit section cited. Confirm this with your permitting authority.

What this means for a generated plan

On what we verified, an operator may adopt a generated plan here without a credentialed signature. Local ordinances can still impose a stricter gate than state law, so check the county or municipality as well.

State*

Activity*

Total acres disturbed*

Total land disturbance over the whole project, including staging and access. This decides whether you need a permit at all.

Acres open at any one time

Optional. If you phase the work, the most that will be disturbed at once. Leave blank if the whole site is open together. The stabilisation deadline turns on this figure, not the total.

Part of a larger common plan of development or sale

A half acre lot inside a 40 acre subdivision is covered even though the lot alone is under the threshold. This is the most commonly missed trigger in the permit.

Receiving water and site conditions(optional, but they change the inspection frequency)

Discharges to a sediment or nutrient impaired water

Discharges to a Tier 2, 2.5 or 3 water

Arid, semi arid or drought stricken area

May allow a reduced inspection frequency during the seasonally dry period.

What people ask about preparing a SWPPP in Arizona

Do I need a qualified preparer for a SWPPP in Arizona?

We found no state level preparer credential for Arizona. On what we verified, an operator may adopt the plan without a credentialed signature. Local ordinances can still be stricter.

Does a professional engineer have to stamp the plan in Arizona?

Practice act citations are routinely overstated on this point. A PE stamp is not required as a general matter in most states with no preparer gate, and where we have not verified it we will not assert either answer. Confirm with the state board or the permitting authority.
