Air quality operating permits contain all applicable requirements for all emission points at a facility, including construction permit terms and other federal regulatory requirements.  There are two types of operating permits, based on a facility’s emissions:

Major Source Operating Permit

Facilities requiring a Major Source Operating Permit (also known as a Class I or Title V permit) have a potential-to-emit above one or more of the following levels:

  • 100 tons per year (tpy) of any criteria air pollutant* excluding lead; 
  • 10 tpy of any single hazardous air pollutant (HAP) or 25 tpy of a combination of HAPs; or 
  • 5 tpy of lead.

    * Criteria pollutants are particulate matter less than 10 microns (PM10), nitrous oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO), volatile organic compounds (VOCs), and lead.

Potential emissions are based on operating the unit/source 24 hours per day at maximum capacity for twelve months or 8,760 hours.

Minor Source Operating Permit

Under Nebraska Title 129 and Omaha Municipal Code Section 41-2 Chapter 5, certain facilities may qualify for a Minor Source (or Class II) Operating Permit.  Class II facilities are divided into two categories:

  • Synthetic Minor:
    • Potential-to-emit above Class I levels, and
    • Enforceable permit limits are taken to reduce potential-to-emit to below Class I levels
  • True Minor (or Natural Minor)
    • Potential-to-emit below Class I levels
    • Actual emissions above the following levels:
      • 25 tons per year (tpy) of PM10
      • 25 tpy of SOx
      • 25 tpy of NOx
      • 25 tpy of VOCs
      • 25 tpy of CO
      • 1.25 tpy of Lead
      • 2.5 tpy of any one Hazardous Air Pollutant (HAP) or 6.25 tpy total HAPs

Permitting Process

Facilities that meet the criteria for an Air Operating Permit are required to submit their application within 12 months of beginning operation or within 12 months of becoming subject to these requirements, whichever is earlier.  Contact OAQC at 402-444-6015 to assist you as you begin your operating permit application process.
