2.18 Multiple-Chamber Incinerator

Any article, machine, equipment, contrivance, structure or part of a structure, used to dispose of combustible refuse by burning, consisting of two or more refractory lined combustion furnaces in series, physically separated by refractory walls, interconnected by gas passage ports or ducts and employing adequate design parameters necessary for maximum combustion of the material to be burned.  The refractories shall have a Pyrometric Cone Equivalent of at least 17, tested according to the method described in the American Societies of Testing Materials, Method C-24.

2.19 Oil-Effluent Water Separator

2.24 Process Weight per Hour

The total weight of all materials introduced into any specific process which process may cause any discharge into the atmosphere.  Solid fuels charged will be considered as part of the process weight, but liquid and gaseous fuels and combustion air will not.  The process weight per hour will be derived by dividing the total process weight by the number of hours in one cycle of operation from the beginning of any given process to the completion thereof, excluding any time during which the equipment is idle.

2.28.1 results in the separation of the air contaminants from the process materials or in the conversion of the process materials into air contaminants, as in the case of combustion of fuels; and,
2.28.2 is not an air pollution abatement operation.

2.29 Volatile Organic Compound (VOC)

Any compound of carbon, excluding exempt compounds as defined at Section 2.10 above, which participates in atmospheric photochemical reactions. When used in District permits, the terms "reactive organic gas" and "reactive organic compound" shall be synonymous with "volatile organic compound".
