SWPPP Requirements in Utah

Who needs a SWPPP in Utah?

Any construction project that disturbs one acre or more — or is part of a larger common plan of development reaching one acre — needs a SWPPP under Utah permit UTRC00000.

Utah runs its own delegated stormwater program. Operators obtain coverage from DWQ under UPDES General Permit for Storm Water Discharges from Construction Activities (UTRC00000) (UTRC00000), not directly from the EPA. A small subdivision, a solar pad, and a road-widening project all clear the same one-acre line.

Utah adds requirements worth flagging early: Develop the SWPPP, submit the NOI through EPA’s NeT-CGP with the permit fee, and receive written authorization before discharging; the fee covers one year, so renew coverage annually for longer projects (UTRC00000 Part 1.4); Submit the NOI package, Authorization to Discharge letter, and SWPPP to the regulated MS4 where the site is located (UTRC00000 Part 1.4); Submit NOI changes (owner/operator or site name, disturbed area, receiving waters) through NeT within 30 days (UTRC00000 Part 1.4.3); Post notice of permit coverage at the site (UTRC00000 Part 1.5); Keep a corrective action log (UTRC00000 Part 5.4); A qualified SWPPP writer must write or certify the SWPPP for sites over 5 acres, or 1–5 acre sites with a perennial water within 50 feet or a qualifying steep slope (UTRC00000 Part 7.2).

What the plan must contain

A Utah SWPPPis the site's compliance binder — the document an inspector opens first. It documents:

1. 1Site & project descriptionTotal and disturbed acreage, soils, slopes, and the sequence of construction.
2. 2Receiving waters & discharge pointsWhere stormwater leaves the site and the waterbodies it reaches.
3. 3Erosion & sediment control BMPsSilt fence, stabilized entrances, inlet protection, and stabilization measures.
4. 4Inspection schedule & recordsDated, signed inspection logs and the corrective actions taken.
5. 5Operator certificationThe SWPPP is signed by the legally responsible party before work begins.

Required and conditional BMPs

Filing your Notice of Intent

Develop the SWPPP, then submit the NOI electronically through EPA’s NPDES eReporting Tool (NeT-CGP, via CDX) with the permit fee and receive DWQ’s written Authorization to Discharge before discharging; a paper NOI is allowed only with a DWQ waiver.

A Notice of Termination closes coverage once the site reaches final stabilization. Keeping the SWPPP and its inspection records on site is what keeps a project clear of stop-work orders.

Inspection requirements

The permit allows 2 inspection schedules; the operator follows one and records the choice in this plan: (a) 7-day schedule — inspect at least once every 7 calendar days (inspections are only required during the site’s normal working hours) (UTRC00000 Part 4.2.1); or (b) 14-day schedule with storm and snowmelt inspections — inspect at least once every 14 calendar days and within 24 hours of the occurrence of a storm producing 0.5 inch of rain or more within a 24-hour period (or of runoff from snowmelt sufficient to cause a discharge; during normal working hours; one inspection within 24 hours of when 0.5 inches has fallen, including several smaller storms that together produce 0.5 inches in 24 hours; for a storm producing 0.5 inches or more on consecutive days, inspect within 24 hours of the first day and within 24 hours after the last such day; keep a rain gauge on site or use a representative weather station) (UTRC00000 Parts 4.2.2–4.2.3). Reduced frequencies are in UTRC00000 Part 4.4. Every inspection is dated and signed, and any failed control is corrected before the next storm.

How Utah differs from the federal permit

Because Utah administers its own program, the federal EPA Construction General Permit does not apply directly here — the state permit governs. Sites inside a regulated municipal storm sewer system may carry additional local ordinance requirements on top of the state permit.
