Air Emission Construction Permit Requirements for the City of Omaha

by Dan May, Air Quality Control Technician, City of Omaha – Air Quality Control

The City of Omaha’s Air Quality Control Division (OAQC) would like to remind contractors working in Omaha that, in addition to the other permits you may be required to obtain, your projects may also require air emission permits. Any construction of a new unit with potential air pollutant emissions above certain thresholds requires the issuance of an Air Emission Construction Permit. In practical terms, this means most stationary engines, including emergency generators (usually those 250 kW and above), as well as large boilers (usually 10 MMBtu and larger). These Air Emission Construction Permits are required before the emission unit is purchased, constructed, reconstructed, or modified. Since the application and permit issuance process can take some time, it is highly recommended that an application be submitted early in the project planning stage.

While the responsibility to obtain these permits ultimately lies with the owner or operator of the new unit, the failure to submit a timely permit application can delay or halt a project. OAQC asks that you keep these requirements in mind and remind your clients of them when planning to install a new generator, large boiler, or other emission unit. If you or your client suspect the planned unit may require an Air Emission Construction Permit – or are unsure what the potential emissions of a new unit will be – please call OAQC at (402) 444-6015 and we will be happy to work with you to make sure the unit is in compliance.
