​​An incinerator is a combustion device that uses high temperatures to turn waste material into ash.  In Sacramento County, the most common types of incinerators are used at human and animal crematories.  Most crematories use enclosed incinerators equipped with an afterburner.  Crematory chambers reach very high temperatures in order to completely incinerate materials.  Because human and animal fat store toxins, the incineration of bodies results in toxic emissions.

Who Needs a Permit?

  • All crematories require a permit to operate from Sac Metro Air District.

Permit Fees 

New Installations: 

  • Use Schedule 4 (see Rule 301, Section 308.5).  Fees are based on the maximum horizontal inside cross-sectional area, in square feet, of the primary combustion chamber.   Use the Initial Permit Fee column for new installations or equipment not previously permitted.


  • For modifications of permitted equipment resulting in an increase in rating, the fee is assessed in accordance with fee schedule 4 (see Rule 301, Section 308.5) based on the incremental increase in horizontal inside cross-sectional area, in square feet, of the primary combustion chamber resulting from such change.

  • For modifications resulting in no increase in rating, the fee will be based on Rule 301, Section 306.2.

Equipment Installed Without an Authority to Construct: 

As per Section 302.1 of Rule 301, any person installing/operating regulated equipment without obtaining a permit from the Sac Metro Air District will be required to pay permit renewal back fees for each year of unpermitted operation, to a maximum of 3 years, in addition to the initial permit fee. 

 Permit Application Completeness Determination

An application will not be accepted for processing until it is deemed complete. The following will be required in order for the Sac Metro Air District to make a completeness determination:
