California coastal waters or are on the Outer Continental Shelf), and 

c) are under the same or common ownership, operation, or control or which are owned or operated by 

entities which are under common control.

described above; and emissions from the loading and unloading of cargo. The term "Cargo Carrier" shall 

not include trains or vehicles. 

As applied to an attainment pollutant, “stationary source” shall be interpreted to mean facility wide. The 

term “installation” shall have the same meaning as “building, structure, or facility.”

“Temporary Total Enclosure” means any total enclosure that is constructed for the sole purpose of 

measuring the emissions from an affected source that are not delivered to an emission control device. A 

temporary total enclosure must be constructed and ventilated (through stacks suitable for testing) so that it has 

minimal impact on the performance of the permanent emission capture system. A temporary total enclosure 

will be assumed to achieve total capture of fugitive emissions if it meets the requirements found in 40 CFR 

Section 63.750(g)(4) and if all natural draft openings are at least four duct or hood equivalent diameters away 

from each exhaust duct or hood. Alternatively, the owner or operator may apply to the Control Officer for 

approval of a temporary enclosure on a case-by-case basis.

“Thermal Incinerator” means any device that burns reactive organic compounds or toxic air contaminants in 

air by direct application of heat. Thermal incinerators are usually equipped with burners, refractory lined 

chambers, heat recovery equipment, and process controllers. 

“Total Enclosure” means any permanent structure that is constructed around a gaseous emission source so 

that all gaseous pollutants emitted from the source are collected and ducted through a control device, such 

that 100 percent capture efficiency is achieved. There are no fugitive emissions from a total enclosure. The 

only openings in a total enclosure are forced makeup air and exhaust ducts and any natural draft openings 

such as those that allow raw materials to enter and exit the enclosure for processing. All access doors or 

windows are closed during routine operation of the enclosed source. Brief, occasional openings of such doors 

or windows to accommodate process equipment adjustments are acceptable, but if such openings are routine 

or if an access door remains open during the entire operation, the access door must be considered a natural 

draft opening. The average inward face velocity across the natural draft openings of the enclosure shall be 

calculated including the area of such access doors. The drying oven itself may be part of the total enclosure. 

An enclosure that meets the requirements found in 40 CFR Section 63.750(g)(4) is a permanent total 

enclosure.
