Who may prepare a stormwater plan in Utah

Utah requires a credentialed preparer only in some cases. Sites above 5 acres.

The answer

Conditional

Utah requires a credentialed preparer only in some cases. Sites above 5 acres.

What triggers it: Sites above 5 acres.

Credentials that qualify

  • Utah Registered SWPPP Writer (RSW)
  • Licensed Professional Engineer (PE) in a related field
  • Professional Geologist (PG)
  • Certified Professional in Erosion and Sediment Control (CPESC)
  • Certified Professional in Storm Water Quality (CPSWQ)
  • National Institute for Certification in Engineering Technologies (NICET), Erosion and Sediment Control, Level 3

The gate is not a flat 5-acre cutoff: Part 7.2 requires a qualified SWPPP writer for any project disturbing more than 5 acres, AND for small (1-5 acre) projects that have a perennial surface water within 50 feet or a steep slope (70% or 35 degrees or more, with 10+ feet of elevation change). Below that threshold, no certified preparer is required at all. A PE stamp is explicitly not required by itself — a licensed PE (or PG) is one of five interchangeable acceptable qualifications alongside RSW, CPESC, CPSWQ and NICET Level 3, commonly overstated as mandatory. Verified against the permit's Part 7.2 text and independently cross-checked against a March 2026 official SWPPP compliance-evaluation checklist for the current permit, which cites identical section numbers and triggers.

What this means for a generated plan

Where a credential applies, or where we cannot confirm that none does, treat a generated document as a complete draft for a credentialed preparer to review, amend and sign. It is not by itself a compliant filed plan, and ours says so on its face.

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

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.

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)

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

What people ask about preparing a SWPPP in Utah

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

Utah requires a credentialed preparer only in some cases. Sites above 5 acres.

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

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.
