Nebraska’s requirements regarding clean air operating permits include some regulatory information beyond the federal requirements. A summary of the additional requirements includes:

The State of Nebraska’s Title V operating permit program is referred to as the Class I operating permit program. Although the Federal Title V program only regulates major sources of air pollution, the Nebraska program also regulates certain minor sources using Class II operating permits.

Fees: Permit fees apply

Thresholds: An operating permit is required for all sources that have actual emissions that are equal to or greater than the Class II thresholds as defined in “Major vs Minor Source” and “Class I and Class II Permits.” The type of permit that is required is as follows:

• A Class I Operating Permit is required if actual emissions are at or above the Class I thresholds;
• Either a Class I or Class II Permit is required if actual emissions are greater than the Class II thresholds, and potential emissions are greater than the Class I thresholds;
• A Class II Operating Permit is required if potential and actual emissions are between the thresholds.

A source has No Operating Permit Required Status if actual emissions are less than the Class II thresholds and potential emissions are less than the Class I thresholds.

Major Source: as defined in Chapter 2 of Title 129, are those sources that emit or have the potential to emit any air pollutant in quantities greater than 100 tons per year (tpy). Lower thresholds exist for lead (5 tpy) and for other hazardous air pollutants: 10 tpy of any single hazardous air pollutant (HAP) or 25 tpy of a combination of HAPs.

Minor Source: as defined in Chapter 1 of Title 129, any source that is not defined as a major source in Chapter 2.

Differences in regions: Nebraska has designated five basic Air Quality Control Regions. Check with the region for permitting differences.  NAC 129-2.004
