PART 1 GENERAL

1.1 Purpose
The purpose of this Rule is to limit emissions of vapors from the use of organic solvents.

1.2 Applicability
The provisions of this Rule shall apply to any equipment or process that uses organic solvents, unless specifically exempted.

1.3 Exemptions
The requirements of this Rule shall not apply to the following:

1.3.1 The manufacture of organic solvents, or the transport or storage of organic solvents or materials containing organic solvents.

1.3.2 The use of equipment or surface coating material for which other requirements are specified by other rules of the District, including Rules 417, 418, 419, 420, and 426 or which are exempt from the air pollution control requirements of said Rules.

1.3.3 The spraying or other use of insecticides, pesticides or herbicides.

1.3.4 The use, application, evaporation or drying of saturated halogenated hydrocarbons or perchloroethylene.

1.3.5 The use of any material, in any equipment described in Part 3 if all of the following apply:

1.3.5.1 the volatile content of such material consists only of water and organic solvents,

1.3.5.2 the organic solvents comprise not more than 20 percent of said volatile content,

1.3.5.3 the volatile content is not photochemically reactive as defined in Section 2.3, and

1.3.5.4 the organic solvent or any material containing organic solvent does not come into contact with flame.

1.3.6 The use of any material in any equipment described in Part 3 if all of the following apply:

1.3.6.1 the organic solvent content of such material does not exceed 20 percent by volume of said materials,

1.3.6.2 the volatile content is not photochemically reactive as defined in Section 2.3,

1.3.6.3 more than 50 percent by volume of such volatile material is evaporated before entering a chamber heated above ambient application temperature, and

1.3.6.4 the organic solvent or any material containing organic solvent does not come into contact with flame.

1.3.7 The use of any material, in any equipment described in Part 3, if all of the following apply:

1.3.7.1 the organic solvent content of such material does not exceed five percent by volume of said material,

1.3.7.2 the volatile content is not photochemically reactive as defined in Section 2.3, and

1.3.7.3 the organic solvent or any material containing organic solvent does not come into contact with flame.

1.4 Effective Dates
This Rule has been in effect since September 1, 1974. This Rule in its present form is effective July 20, 1994.

1.5 References
The requirements of this Rule arise from the provisions of the California Clean Air Act and amendments (Health and Safety Code Section 40910 et seq.) and the federal Clean Air Act and amendments (42 U.S.C. Section 7401 et seq.).

PART 2 DEFINITIONS

2.1 Equipment
Any article, machine, equipment or other contrivance.

2.2 Organic Solvents
Liquids containing chemical compounds of carbon which are used as dissolvers, viscosity reducers or cleaning agents. The following carbon compounds are not considered organic solvents: ammonium carbonate, carbon dioxide, carbon monoxide, carbonic acid, and metallic carbonates.

2.3 Photochemically Reactive Solvent
Any solvent with an aggregate of more than 20 percent of its total volume composed of the chemical compounds classified below or which exceed any of the following individual percentage composition limitations, referred to the total volume of solvent:

2.3.1 a combination of hydrocarbons, alcohols, aldehydes, esters, ethers or ketones having an olefinic or cyclo-olefinic type of saturation:  5 percent;

2.3.2 a combination of aromatic compounds with eight or more carbon atoms to the molecule except ethylbenzene: 8 percent; or

2.3.3 a combination of ethylbenzene, ketones having branched hydrocarbon structures, trichloroethylene or toluene: 20 percent.

Whenever any organic solvent or any constituent of an organic solvent may be classified from its chemical structure into more than one of the above groups of organic compounds, it shall be considered as a member of the most reactive chemical group; that is, that group having the least allowable percentage of the total volume of solvents.
 

PART 3 REQUIREMENTS AND STANDARDS

3.1 Equipment Exposing Solvent to Flame or Oxidizing Conditions
A person shall not cause or allow the uncontrolled emissions of more than 15 pounds of organic solvent vapors in any one day, nor more than three pounds in any one hour, from any equipment in which any organic solvent or any material containing organic solvent comes into contact with flame or is baked, heat-cured or heat-polymerized, in the presence of oxygen.

3.1.1 Emissions from all equipment designed for processing a continuous web, strip or wire shall be collectively subject to compliance with this Section.

3.1.2 Emissions resulting from the cleanup with photochemically reactive solvent, as defined in Section 2.3, of any equipment described in Part 3 shall be included with the other emissions from that equipment for determining compliance with this Rule.

3.2 Equipment Using Photochemically Reactive Solvents
A person shall not cause or allow the uncontrolled emissions of more than 40 pounds of organic solvent vapors in any one day, nor more than eight pounds in any one hour, from any equipment used under conditions other than described in Section 3.1, for using, or applying any photochemically reactive solvent, as defined in Section 2.3, or material containing such photochemically reactive solvent.

3.2.1 Emissions resulting from air or heated drying of products for the first 12 hours after their removal from any equipment using photochemically reactive solvent shall be included in determining compliance with Section 3.2.

3.2.2 Emissions resulting from baking, heat-curing or heat-polymerizing, as described in Section 3.1, shall be excluded from determination of compliance with Section 3.2.

3.2.3 Emissions from all equipment designed for processing a continuous web, strip or wire shall be collectively subject to compliance with Section 3.2.
