f. Emissions of organic materials into the atmosphere required to be controlled by sections (a), (b) or (c), shall be reduced by:

(1) Incineration, provided that 90 per cent or more of the carbon in the organic material being incinerated is oxidized to carbon dioxide, or

(2) Adsorption, or

(3) Processing in a manner determined by the Air Pollution Control Officer to be not less effective than (1) or (2) above.

g. A person incinerating, adsorbing, or otherwise processing organic materials pursuant to this rule shall provide, properly install and maintain in calibration, in good working order and in operation, devices as specified in the authority to construct or the permit to operate, or as specified by the Air Pollution Control Officer, for indicating temperatures, pressures, rates of flow or other operating conditions necessary to determine the degree and effectiveness of air pollution control.

h. Any person using organic solvents or any materials containing organic solvents shall supply the Air Pollution Control Officer, upon request and in the manner and form prescribed by him, written evidence of the chemical composition, physical properties and amount consumed for each organic solvent used.

i. The provisions of this rule shall not apply to:

(1) The manufacture of organic solvents, or the transport or storage of organic solvents or materials containing organic solvents.

(2) The use of equipment for which other requirements are specified by Rules 56, 59, 61 or 65 or which are exempt from air pollution control requirements by said rules.

(3) The spraying or other employment of insecticides, pesticides or herbicides.

(4) The employment, application, evaporation or drying of saturated halogenated hydrocarbons or perchloroethylene.

j. For the purposes of this rule, organic solvents include diluents and thinners and are defined as organic materials which are liquids at standard conditions and which are used as dissolvers, viscosity reducers or cleaning agents.

k. For the purposes of this rule, a photochemically reactive solvent is any solvent with an aggregate of more than 20 per cent of its total volume composed of the chemical compounds classified below or which exceeds any of the following individual percentage composition limitations, referred to the total volume of solvent:

(1) A combination of hydrocarbons, alcohols, aldehydes, esters, ethers or ketones having an olefinic or cycloolefinic type of unsaturation: 5 per cent;

(2) A combination of aromatic compounds with eight or more carbon atoms to the molecule except ethylbenzene: 8 per cent;

(3) A combination of ethylbenzene, ketones having branched hydrocarbon structures, trichloroethylene or toluene:

20 per cent.

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 per cent of the total volume of solvents.

1. For the purposes of this rule, organic materials are defined as chemical compounds of carbon excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides, metallic carbonates and ammonium carbonate.

m. This rule shall be effective on the date of its adoption as to any article, machine, equipment or other contrivance, not then completed and put into service. As to all other articles, machines, equipment or other contrivances, this rule shall be effective:

(1) On July 1, 1967, for those emitting 500 pounds or more of organic materials in any one day.

(2) On October 1, 1967, for those emitting 100 pounds or more but less than 500 pounds of organic materials in any one day.

(3) On March 1, 1968, for those subject to compliance with section (a), and emitting 15 pounds or more but less than 100 pounds of organic materials in any one day, and for those subject to compliance with section (b), and emitting 40 pounds or more but less than 100 pounds in any one day.

RULE 66.1 (Adopted 7-28-66) ARCHITECTURAL COATINGS.

a. After July 1, 1967, a person shall not sell or offer for sale for use in Los Angeles County, in containers of one quart capacity or larger, any architectural coating containing photochemically reactive solvent, as defined in Rule 66(k).

b. After July 1, 1967, a person shall not employ, apply, evaporate or dry in Los Angeles County any architectural coating, purchased in containers of one quart capacity or larger, containing photochemically reactive solvent, as defined in Rule 66(k).

c. After July 1, 1967, a person shall not thin or dilute any architectural coating with a photochemically reactive solvent, as defined in Rule 66(k).

d. For the purposes of this rule, an architectural coating is defined as a coating used for residential or commercial buildings and their appurtenances; or industrial buildings.

RULE 66.2 (Adopted 7-28-66) DISPOSAL AND EVAPORATION OF SOLVENTS. A person shall not during any one day dispose of a total of more than 1%1⁄2 gallons of any photochemically reactive solvent, as defined in Rule 66(k), or of any material containing more than 1% gallons of any such photochemically reactive solvent by any means which will permit the evaporation of such solvent into the atmosphere.
