SWPPP Requirements in Nebraska

Who needs a SWPPP in Nebraska?

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 Nebraska permit NER210000.

Nebraska runs its own delegated stormwater program. Operators obtain coverage from DWEE; formerly NDEE under General NPDES Permit for Storm Water Discharges from Construction Sites to Waters of the State of Nebraska (CSW-2021) (NER210000), not directly from the EPA. A small subdivision, a solar pad, and a road-widening project all clear the same one-acre line.

Nebraska adds requirements worth flagging early: Submit the CSW-NOI online with the SWPPP, a site map, and a Nebraska Game and Parks Commission CERT review; discharge is authorized 7 calendar days after a complete and accurate submittal unless NDEE delays it (Parts II.A–II.B); Where discharging through an MS4, send the MS4 operator a copy of the CSW-NOI and the approval letter before construction starts (Part II.D.2); Post a sign near the site entrance with a copy of the CSW-NOI and either the SWPPP or the contact and location for obtaining it (Part IV.L.2); Remove sediment tracked onto off-site streets, paved areas, and sidewalks by the end of the same work day (next work day if on a non-work day) (Part IV.C.5.d); Remove sediment from traps and ponds when design capacity is reduced by 50 percent (Part IV.F.8.e); Submit the CSW-NOT within 30 days of final stabilization (70 percent perennial vegetative cover) or another termination condition; a change of certifying official requires a new CSW-NOI within 7 calendar days (Parts VI.A, VI.C).

What the plan must contain

A Nebraska 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

Submit the construction storm water Notice of Intent (CSW-NOI), with the SWPPP and Game and Parks CERT review, through the DWEE online application for Construction Storm Water.

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 (excluding nonbusiness hours) (NER210000 Part VII.A.1.a); or (b) 14-day schedule with storm inspections — inspect at least once every 14 calendar days and within 24 hours of the occurrence of a storm producing 0.25 inch of rain or more (also within 24 hours of the occurrence of runoff from snowmelt sufficient to cause a discharge; excluding nonbusiness hours) (NER210000 Part VII.A.1.b). Linear projects may conduct representative inspections at the permit-specified frequency, covering a quarter mile above and below access points (NER210000 Part VII.A.4). Every inspection is dated and signed, and any failed control is corrected before the next storm.

How Nebraska differs from the federal permit

Because Nebraska 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.
