machines include, but are not limited to, batch cold, batch vapor, in-line cold, in-line vapor, remote reservoir, 

and gas-path solvent cleaners, as defined in Rule 321. Buckets, pails, and beakers with capacities of 3.785 

liters (1.00 gallon) or less are not considered solvent cleaning machines. However, the use of such a 

container or similar containers (e.g., hand-held spray bottles) with a solvent for cleaning is considered to be 

solvent cleaning. Any device or piece of equipment used exclusively for stripping shall not be considered to 

be a solvent cleaning machine. 

“Spark Ignition Engine” means a gasoline-fueled engine or other engine with a spark plug (or other sparking

scope of drilling or construction activities; and 
Santa Barbara County APCD Rule 102 102 - 12 September 20, 2010[date of amended rule adoption]

4. The equipment will be used for less than 500 hours per stationary source in any calendar year and 

emit not more than 10 tons per stationary source of oxides of nitrogen, oxides of sulfur, reactive 

organic compounds, or particulate matter in any calendar year; and 

5. Use of the equipment is not recurrent from year to year. 

“Specialty Equipment Emergency Use” means that conditions giving rise to the use of the specialty

affected pollutant directly or as a fugitive emission. “Fugitive emissions” means those emissions of 

pollutants which could not reasonably pass through a stack, chimney, vent or other functionally equivalent 

opening. 

“Installation” includes any operation, article, machine, equipment, contrivance, or grouping of equipment 

belonging to the same two-digit standard industrial classification code, which emits or may emit any 

affected pollutant, and located on one or more contiguous properties and under common control. 

“Building, structure, or facility” includes all pollutant-emitting activities including those

of Outer Continental Shelf waters for which the District is the corresponding onshore 

area which: 

a) belong to the same industrial grouping 

b) are located on one or more contiguous or adjacent properties (except for activities located in 

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. 

Pollutant emitting activities shall be considered as part of the same industrial grouping if they are 

part of a common production process. (Common production process includes industrial processes, 

manufacturing processes, and any connected processes involving a common raw material.) 

“Common operations” includes operations which are related through dependent processes, storage or 

transportation of the same or similar products or raw material. Emissions from all marine vessels, 

including cargo carriers, servicing or associated with a stationary source shall be considered emissions 

from the stationary source while operating within:
