Air Permitting

Air Permit determination and writing

Does my facility need an Air Permit? This can depend on several factors. Federal regulations require each major source of air pollutant emissions to obtain an "operating permit" that consolidates all of the air pollution control requirements into a single, comprehensive document covering all aspects of the source's air pollution activities. Air pollution permits are also required for businesses that build new pollution sources or make significant changes to existing pollution sources.

ESSG’s Environmental Engineers will perform an Air Permit Initial Evaluation that includes the following steps to determine if a permit is required for your facility. The evaluation includes local, state and federal guidelines. The evaluation steps are:


  1. Gather inventory and usage information;

  2. Evaluate your processes;

  3. Calculate emissions from each process;

  4. Cross reference your emissions with federal, state and local regulations;

  5. Determine if your emissions surpass permitting thresholds and require an air permit and if so, what type of permit; and

  6. Submit to you a report outlining your permitting requirements.


If a permit is not required, we provide you with the appropriate reports and documentation to show regulators that your facility does not require an air permit at this time.


If a permit is required, by completing this initial evaluation, we will have already completed the 5 initial steps needed to complete the permit process. We will then be able to better determine the amount of time it would take to complete the permit process. Therefore, upon your request, we will generate a quote to cover the remaining steps.


If it is determined that an Air Permit is required and on your approval, we then proceed with the Air Permit Writing Phase.


The Air Permit Application and Writing phase includes the following:

  1. Submit Permit Application OR Applicability Determination to your state’s environmental agency;

  2. Provide all necessary data requested by your state’s environmental agency to support permit application; and

  3. Work with your state’s environmental agency to define permit requirements
