102 Final Staff Report 

I. BOARD ADOPTION 

Rule 102, Definitions was amended by the Kern County Air Pollution Control 

District’s Governing Board on March 11, 2010 at the March 2010 Board meeting. 

II. INTRODUCTION 

This staff report presents the amendments made to Rule 102 Definitions. The 

primary reason for amending the Rule is to update the Exempt Compounds list to 

conform to the Exempt Compounds list of the EPA. Four (4) definitions have also 

been added to the Rule along with modifications to Standard Conditions and 

minor formatting. 

Appendix A is the clean version of amended Rule 102 Definitions. 

Appendix B is the strikeout underline version of amended Rule 102 Definitions. 

Appendix C is the Response to Comments that followed the October 28, 2009 

workshop. 

III. TROPOSPHERIC OZONE 

Tropospheric ozone (ozone), commonly known as smog, occurs when VOCs and 

nitrogen oxides (NOx) react in the atmosphere. Because of the harmful health 

effects of ozone, EPA, State, and local governments limit the amount of VOCs 

and NOx that can be released into the atmosphere. 

IV. VOLATILE ORGANIC COMPOUNDS (VOC) 

Volatile organic compounds are any compound containing at least one atom of 

carbon (excluding negligibly reactive compounds) which form ozone through 

atmospheric photochemical reactions. Compounds of carbon (also known as 

organic compounds) have different levels of reactivity--that is, they do not react 

at the same speed or do not form ozone to the same extent. 

V. EXEMPT COMPOUNDS 

Compounds that have low atmospheric photochemical reactions are considered 

to have a negligible level of reactivity. It has been EPA's policy that organic 

compounds with a negligible level of reactivity do not need to be regulated to 

reduce ozone. The EPA lists negligibly reactive compounds in its regulations (at 

40 CFR 51.100(s)) and excludes them from the definition of VOCs. 

The following list of negligibly reactive compounds has been added to the 

Exempt Compounds list (Section N) in Rule 102 Definitions:

exempted Tertiary Butyl Acetate (t-butyl acetate) informally known as TBAC or 

TBAc with the following special provisions: TBAc will not be a VOC for purposes 

of VOC emissions limitations or VOC content requirements, but will be a VOC for 

purposes of all recordkeeping, emissions reporting, photochemical dispersion 

modeling, and inventory requirements which apply to VOC. TBAc shall also be 

uniquely identified in emission reports.

102 Final Staff Report 

VII. NEW DEFINITIONS 

Four (4) definitions have been added to Rule 102 Definitions. The new definitions 

have been placed into the Rule alphabetically and are as follows: 

After the EPA’s initial review of the amended version of Rule 102, the EPA 

deemed the District’s definition of Affected Pollutants to be unacceptable. The 

EPA asked the District to broaden the definition to include NSR regulations. 

The revised definition for Affected Pollutants and other new definitions are as 

follows: 

a. Affected Pollutants: Any air contaminant and precursor to such 

contaminant regulated under the Clean Air Act which include: volatile 

organic compounds, nitrogen oxides, sulfur oxides, Particles with 

aerodynamic diameter of 10 micrometers or less (PM10), carbon 

monoxide, ethylene, lead, asbestos, beryllium, mercury, vinyl chloride, 

fluorides, sulfuric acid mist, hydrogen sulfide, total reduced sulfur, and 

reduced sulfur compounds, and those pollutants which the U.S. 

Environmental Protection Agency (EPA), California Air Resources Board 

(ARB), or District, after due process, has determined to have a significant 

adverse effect on the environment, public health, or public welfare. 

b. Ambient Air Quality Standards: State and National Ambient Air Quality 

Standards. (For inclusion of this Rule in the State Implementation Plan, all 

references to ambient air quality standards shall be implemented as 

National Ambient Air Quality Standards.) 

c. Kern County Air Pollution Control District: That portion of Kern County 

which lies east of the line described as follows: 

 Beginning at the Kern-Los Angeles County boundary and running north 

and east along the northwest boundary of the Rancho La Liebre Land 

Grant to the point of intersection with the township line common to 

T.9.N and T.10.N, San Bernardino Base and Meridian (SBB&M); 

 then west along the township line to the range line common to T.10.N, 

R.16.W and T.9.N, R.17.W, SBB&M;

Rancho El Tejon Land Grant to the northwest corner of S.3, T.11.N, 

R.17.W, SBB&M;

d. Volatile Organic Compounds: Any compound containing at least one 

atom of carbon except for exempt compounds listed in section N of this 

rule. 

VIII. STANDARD CONDITIONS

To maintain consistency with EPA, ARB, and other air districts, KCAPCD’s 

Standard Conditions have been updated as follows: 

a. Gas test temperature has been changed from 60 degrees Fahrenheit to 

68 degrees Fahrenheit; and 

b. Gas test pressure has been changed from 29.92 inches of mercury to 14.7 

pounds per square inch (760-millimeters of mercury). 

All analyses and tests shall be calculated or reported at this gas temperature and 

pressure. 

IX. ECONOMIC IMPACT 

Amended Rule 102 Definitions poses no significant cost to industry. 

X. SOCIOECONOMIC IMPACTS 

CHSC Section 40728.5 exempts districts with a population of less than 500,000 

persons from the requirement to assess the socioeconomic impacts of proposed 

rules. Eastern Kern County population is below 500,000 persons. 

XI. ENVIRONMENTAL IMPACTS 

Amended Rule 102 Definitions poses no significant environmental impact.

by the test methods in the approved State implementation plan (SIP) or 40 CFR Part 60,

negligible photochemical reactivity, these negligibly-reactive compounds may be 

excluded as VOC if the amount of such compounds is accurately quantified, and such 

exclusion is approved by the enforcement authority.

3. The following compound is a VOC for purposes of all recordkeeping, emissions 

reporting, photochemical dispersion modeling and inventory requirements which apply 

to VOC and shall be uniquely identified in emission reports, but is not a VOC for 

purposes of VOC emissions limitations or VOC content requirements: Tertiary Butyl 

Acetate (t-butyl acetate) informally known as TBAC or TBAc.

AMENDED RULE 102 DEFINITIONS 

RESPONSE TO COMMENTS 
102 Final Staff Report - Response to Comments 

Appendix C C-1 Draft 4/5/2010 

I. ARB & EPA COMMENTS 

The California Air Resources Board (ARB) had no comments or suggested 

changes for the amended version of Rule 102. 

U.S. EPA (EPA) submitted only one suggested change for the amended version 

of Rule 102. EPA’s suggested change is as follows: 

The District has added the term “affected pollutant” and defined it as pollutants 

for which an air quality standard exists. This is significantly less broad then 

EPA’s term of “NSR regulated pollutant” which includes any pollutant regulated 

under the federal Clean Air Act. This definition is not acceptable if it is the 

District’s intent to rely on it for the purposes of the federal NSR program (minor 

NSR for all pollutants and major NSR for non-attainment pollutants). Please 

revise or add a specific definition for NSR regulated pollutants if this is the term 

to be used in your NSR program. 

To satisfy EPA’s request KCAPCD changed the definition of Affected Pollutants 

from “Air contaminants for which there are ambient air quality standards” to “Any 

air contaminant and precursor to such contaminant regulated under the Clean Air 

Act which include: volatile organic compounds, nitrogen oxides, sulfur oxides, 

Particles with aerodynamic diameter of 10 micrometers or less (PM10), carbon 

monoxide, ethylene, lead, asbestos, beryllium, mercury, vinyl chloride, fluorides, 

sulfuric acid mist, hydrogen sulfide, total reduced sulfur, and reduced sulfur 

compounds, and those pollutants which the U.S. Environmental Protection 

Agency (EPA), California Air Resources Board (ARB), or District, after due 

process, has determined to have a significant adverse effect on the environment, 

public health, or public welfare.” 

II. INDUSTRY COMMENTS 

KCAPCD was commended by industry for updating the Exempt Compounds list 

in Rule 102 Definitions to include Tertiary Butyl Acetate (t-butyl acetate) 

informally known as TBAC or TBAc along with Dimethyl Carbonate and 

Propylene Carbonate which are compounds used in various coatings. 

Industry offered no suggested changes for Rule 102 Definitions. 

III. PUBLIC COMMENTS 

There were no comments made by the general public. 

IV. ARB & EPA RULE REVIEW RESULTS 

KCAPCD submitted the Final Revised Draft of Rule 102 Definitions to ARB and 

EPA for a 30-day review period. At the close of the 30-day review period ARB 

and EPA each stated that there were no additional comments.
