Before burning fat as an alternative fuel you should first check with your local/state regulatory agency to verify whether an air permit or a modification to an existing air permit is needed.

• If you know your air permit engineer, contact him/her and ask how to add fat as an alternative fuel.
• If you don¹t know your air permit engineer, ask to speak to the Supervisor of the Air Permitting Section. Ask what must be done to add fat as an alternative fuel.
• Click here to find a link to your state regulatory agency web site. If the combustion source is currently permitted, you will likely need a permit modification before being allowed to burn fat.
• If the combustion source is smaller than 10 mmBtu/hr, an air permit may not be needed to burn fat.

The permitting process for adding fat as a fuel may take from 30 days to nine months or more depending on various factors that include:

• Current permitting status
• Size/number of combustion units
• Location of the site.

Be sure to advise the air permitting agency if Griffin has already permitted fat as a fuel in your state.

Information on emissions from burning fats may be found on the University of Georgia Engineering Outreach Services web site.
