Industrial Stormwater Permit

Industrial Stormwater Permit

Below is a copy of the Nebraska Department of Environmental Quality (NDEQ) Industrial Stormwater (ISW) permit and associated appendices.  The NDEQ has established 30 Sectors, grouped by similar industrial activity.  Industries with one or more Standard Industrial Classification (SIC) codes included on the Sector list are required to apply for coverage under the NDEQ ISW permit.  The Sector list is included in Appendix D of the NDEQ ISW permit.  The Permit Application and associated forms are included as attachments of the permit.

The terms of the NDEQ ISW permit include the requirement for the creation and implementation of a Storm Water Pollution Prevention Plan (SWPPP).  Facilities that have limited exposure of potential pollutants to stormwater can apply for exclusion from permitting under a No Exposure Certification (NEC) with the NDEQ.  The NDEQ NEC Form is available here:

Contact the Stormwater Hotline at 402-444-3908 for more information.

The goal of this element is to reduce pollutants that can result from business or industrial activities. To do this, the City of Omaha is working with the NDEQ by implementing the NDEQ ISW permit program. City staff will provide assistance to commercial and industrial facilities to reduce inappropriate disposal of pollutants. The City is required by the NDEQ to inspect specific types of industrial and commercial facilities for proper stormwater pollution reduction activities.   

Frequently Asked Questions


What is the cost of applying for permit authorization or No Exposure Certification?

The Nebraska Department of Environmental Quality does not charge an application fee for their Industrial Stormwater Permit or No Exposure Certification.

What is required for a full Industrial Stormwater Permit?

The permit requires that facilities develop and implement a Stormwater Pollution Prevention Plan (SWPPP) that is designed to eliminate or minimize stormwater contact with materials that may result in polluted stormwater discharges from their site.  The SWPPP must incorporate specific best management practices (BMPs) applicable to the site.

What is required in the Stormwater Pollution Prevention Plan (SWPPP)?

The SWPPP is a “living” document that is intended to be regularly updated and must be kept on site.  The SWPPP consists of a Narrative and Site Maps.  The SWPPP must include:

  • Identification of the Pollution Prevention Team
  • Site description
  • Receiving waters and wetlands
  • Identification and location of potential pollutant sources
  • Stormwater controls
  • Identification of Best Management Practices
  • Schedules and procedures
  • Associated documentation
  • Required certification and signatures

For additional information, references Section 5 of the NDEQ ISW permit (pg 24).

The SWPPP requirements mention Best Management Practices (BMPs), what are BMPs?

BMPs are practices or structures designed to reduce the quantities of pollutants that enter the storm sewer system or nearby lakes and creeks.  Practices such as employee training, spill prevention and response, and regular inspections are just a few examples of BMPs.  Structural BMPs could include secondary containment, stormwater detention basins, stormwater retention basins, grass swales, and more.

For a list of BMPs specific to your industry, please see the Industry Fact Sheets page.

What else should I expect once I’ve received permit authorization or No Exposure Certification?

The City of Omaha will conduct inspections as required by the City’s Municipal Stormwater Permit issued by the State of Nebraska.  At the time of the inspection, inspectors will review the storage and usage practices of materials, the site’s SWPPP and supporting documentation (if required), and overall compliance with the permit or No Exposure Certification.

What are typical things that Inspectors will look for?

Sources of stormwater pollution that inspectors will typically look for include, but are not limited to, the following:

  • Discharge from commercial vehicle washing, equipment washing, or power washing into the storm drainage system.
  • Evidence that work areas such as oily service bays are being hosed out and discharged into the storm drainage system.
  • Evidence of dumping materials and waste into the storm drainage system including materials such as concrete, paint, automotive fluids, etc.
  • Leakage from barrels and other outdoor containers.
  • Failure to properly manage leaks and spills.
  • Open or leaking dumpsters.
  • Mismanagement of hazardous wastes.
  • Oily, dirty items (such as engine parts or grills) and open containers of liquids or other materials that are left outdoors and exposed to rainfall.
  • Exposure of process activities and equipment to rainfall that is likely to result in pollutant wash-off.
  • Track-out of sediment and other materials from facilities onto roadways, and from indoor areas to outdoor areas.
  • Evidence of failure to maintain grease traps and interceptors.
  • Any other poor housekeeping practices that result in the exposure of pollutants to stormwater.

NOTE: The storm drainage system includes storm inlets, roadside drainage ditches and all man-made and natural water conveyance systems such as channels, creeks, etc.

What will happen if problems are found at my business?

The City of Omaha can pursue enforcement action through the permitting authority specified in the Stormwater Management Ordinance, Chapter 32, of the Omaha Municipal Code.  Consideration for enforcement will be dependent on the severity of the identified problems, the length of time a problem has gone unaddressed, and the business’s promptness in completing necessary corrective actions.

The State’s involvement in enforcement actions will be considered on a case by case basis.

Can anyone help me with the industrial stormwater regulations?
