Background:

On May 13, 2010, as approved by the District’s Governing Board, the Kern 

County Air Pollution Control District (KCAPCD) formally changed the name of the 

District to Eastern Kern Air Pollution Control District (EKAPCD). All definitions in 

the Rule referencing KCAPCD have been revised to now reference EKAPCD. 

Section O, Eastern Kern County Air Pollution Control District has been 

added to the Rule to define the District’s boundaries.

Rule Summary: 

Eastern Kern Air Pollution Control District (EKAPCD) Rule 102, 

Definitions, is being amended to define a number of terms that are used in other 

District rules. The amendments include updating the name of the District, adding 

ten new definitions, revising language in three definitions, and adding one 

compound to the Exempt Compounds list. Minor formatting issues are also 

being corrected. 

New Definitions

The following ten definitions have been added alphabetically to Rule 102:

Agricultural Facility

Carbon Dioxide Equivalent

CO2 Equivalent, or CO2e

Confined Animal Facility (CAF)

Fugitive Dust; Gasoline

Greenhouse Gas, Greenhouses Gases, or GHG(s)

Global Warming Potential or GWP
-3-

Motor Vehicle

Toxic Air Contaminant (TAC)

Vehicle

Revised Definitions

The following three definitions have been revised for clarity and intent as 

follows: 

Affected Pollutants 

Air Contaminants

Volatile Organic Compounds

The term “excluding GHGs as defined in this rule” has been added to the 

definitions of Affected Pollutants and Air Contaminants.

Perchloroethylene (tetrachloroethylene) has been added to the list of 

Exempt Compounds. Although perchloroethylene is excluded from the definition 

of Volatile Organic Compounds because it has been determined to have 

negligible photochemical reactivity, it is still considered a Toxic Air Contaminated 

(TAC) and its use must comply with District, State, and Federal regulations.

The Exempt Compounds list has also been reformatted to maintain 

consistency throughout the entire list.

Eastern Kern APCD does not anticipate any emissions changes or any 

significant impacts to regulated sources resulting from the amendments to Rule 

102.

EPA Evaluation

Amended Rule 102 poses no significant cost to industry and no significant 

environmental impact.

EPA is recommending approval of Eastern Kern County APCD Rule 102

under section 110(k) as meeting the requirements of section 110(a) and Part D of 

the Clean Air Act, as amended in 1990.
