Section 26.11.18.05 - Control of Odors from the Reduction of Offal

A. A person may not cause or permit the use of any installation primarily engaged in the reduction of offal unless all gases, vapors, and gas-entrained matter from the installation are:

(1) First cooled to a temperature of not greater than 160°F (71°C); and then

(2) The non-condensible fraction is incinerated at a temperature of not less than 1400°F (760°C) for a period of not less than 0.4 seconds.

B. Alternate methods may be used if determined by the Department to be equally or more effective for the purpose of controlling air pollution.

C. Any person processing or incinerating gases, vapors, or gas-entrained matter, as required by §A of this regulation, when ordered by the Department, shall install, operate, and maintain in good working order and calibration continuous recording devices for indicating temperature or pressure or other operating conditions. These devices shall be approved by the Department and all data collected, when ordered by the Department, shall be made available to the Department or the control officer for inspection or copying. This data shall be kept on file by responsible persons for at least 5 years.

D. A person may not cause or permit any offal to be handled, transported, or stored, or to undertake the preparation of any offal without taking reasonable precautions to prevent odors from being discharged. Reasonable precautions, when approved by the Department, shall include, but not be limited to, the following:

(1) Storage of all offal, before or in the process of preparation, in properly enclosed and vented equipment or areas, together with the use of effective devices and methods to prevent the discharge of odors bearing gases;

(2) Use of covered vehicles or containers of watertight construction for the handling and transporting of offal;

(3) Use of hoods and fans to enclose and vent the storage, handling, preparation, and conveying of any odorous materials together with effective devices or methods, or both, to prevent emissions of odors or odor bearing gases.

E. Whenever the emissions from an installation primarily engaged in the reduction of offal creates a nuisance or air pollution beyond the property line, the Department may require that the building in which the installation is located be vented so that all emissions are treated by incineration or by other methods if determined by the Department to be equally or more effective for the purpose of controlling emissions.

F. The requirements of this regulation do not apply to any installation engaged exclusively in the processing of food for human consumption.
