For the purpose of this rule, any petroleum distillate having a Reid vapor pressure of four pounds or greater shall be included by the term ''gasoline''.

(Amended 12-4-58) For the purpose of this rule, ''loading facility'' means any aggregation or combination of gasoline loading equipment which is both (1) possessed by one person, and (2) located so that all the gasoline loading outlets for such aggregation or combination of loading equipment can be encompassed within any circle of 300 feet in diameter.

The provisions of this rule shall not apply to:

a.

The burning of sulfur, hydrogen sulfide, acid sludge or other sulfur compounds in the manufacturing of sulfur or sulfur compounds.

d. The use of fuels where the gaseous products of combustion are used as raw materials for other processes.

e. The use of liquid or solid fuel to propel or test any vehicle, aircraft, missile, locomotive, boat or ship.

f. The use of liquid fuel whenever the supply of gaseous fuel, the burning of which is permitted by this rule, is not physically available to the user due to accident, act of God, act of war, act of the public enemy, or failure of the supplier.

di

(1) Any use of fuel described in Subsections a, b,
e, and f of said Rule 62 under the conditions and for
the uses set forth in said Subsections.

(2) The use of liquid fuel during a period for which the supplier of gaseous fuel, the burning of which is not prohibited by this Rule, interrupts the delivery of gaseous fuel to the user.

c. Every holder of, and every applicant for a permit to operate fuel-burning equipment under these Rules and Regulations shall notify the air pollution control officer in the manner and form prescribed by him, of each interruption in and resumption of delivery of gaseous fuel to his equipment.

RULE 63.

(Amended 1-25-62) GASOLINE SPECIFICATIONS.

a. A person shall not, after June 30, 1960, sell or supply for use within the District as a fuel for motor vehicles as defined by the Vehicle Code of the State of California, gasoline having a degree of unsaturation greater than that indicated by a Bromine Number of 30 as determined by ASTM Method D1159-57T modified by omission of the mercuric chloride catalyst.

b. For the purpose of this rule, the term ''gasoline'' means any petroleum distillate having a Reid vapor pressure of more than four pounds.

RULE 64. (Adopted 6-25-59) REDUCTION OF ANIMAL MATTER. A person shall not operate or use any article, machine, equipment or other contrivance for the reduction of animal matter unless all gases, vapors and gas-entrained effluents from such an article, machine, equipment or other contrivance are:

a. Incinerated at temperatures of not less than 1200 degrees Fahrenheit for a period of not less than 0.3 second, or

b. Processed in such a manner determined by the Air Pollution Control Officer to be equally, or more, effective for the purpose of air pollution control than (a) above.

A person incinerating or processing gases, vapors or gasentrained effluents 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 Permit to Operate or as specified by the Air Pollution Control Officer, for indicating temperature, pressure or other operating conditions.

For the purpose of this rule, ''reduction'' is defined as any heated process, including rendering, cooking, drying, dehydrating, digesting, evaporating and protein concentrating.

The provisions of this rule shall not apply to any article, machine, equipment or other contrivance used exclusively for the processing of food for human consumption.

This rule shall be effective on the date of its adoption as to any article, machine, equipment or other contrivance used for the reduction of animal matter not completed and put into service. As to all other such articles, machines, equipment or other contrivances this rule shall be effective October 1, 1959.

RULE 65. (Amended 6-1-65) GASOLINE LOADING INTO TANKS. A person shall not after January 1, 1965, load or permit the loading of gasoline into any stationary tank with a capacity of 250 gallons or more from any tank truck or trailer, except through a permanent submerged fill pipe, unless such tank is equipped with a vapor loss control device as described in Rule 56, or is a pressure tank as described in Rule 56.

The provisions of the first paragraph of this rule shall not apply to the loading of gasoline into any tank having a capacity of less then 2,000 gallons which was installed prior to the date of adoption of this rule nor to any underground tank installed prior to the date of adoption of this rule where the fill line between the fill connection and tank is offset.

Any person operating or using any gasoline tank with a capacity of 250 gallons or more installed prior to the date of adoption of this rule shall apply for a permit to operate such tank before January 1, 1965. The provisions of Rule 40 shall not apply during the period between the date of adoption of this rule and January 1, 1965, to any gasoline tank installed prior to the date of adoption of this rule provided an application for permit to operate is filed before January 1, 1965.

A person shall not install any gasoline tank with a capacity of 250 gallons or more unless such tank is equipped as described in the first paragraph of this rule.

For the purpose of this rule, the term "gasoline" is defined as any petroleum distillate having a Reid vapor pressure of 4 pounds or greater.

For the purpose of this rule, the term submerged fill pipe" is defined as any fill pipe the discharge opening of which is entirely submerged when the liquid level is 6 inches above the bottom of the tank. "Submerged fill pipe" when applied to a tank which is loaded from the side is defined as any fill pipe the discharge opening of which is entirely submerged when the liquid level is 18 inches above the bottom of the tank.

(Adopted 6-1-65) The provisions of this rule do not apply to any stationary tank which is used primarily for the fueling of implements of husbandry, as such vehicles are defined in Division 16 (Section 36000, et seq.) of the Vehicle Code.

A person shall not discharge more than 15 pounds of organic materials into the atmosphere in any one day from any article, machine, equipment or other contrivance 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, unless all organic materials discharged from such article, machine, equipment or other contrivance have been reduced either by at least 85 per cent overall or to not more than 15 pounds in any one day.

b. A person shall not discharge more than 40 pounds of organic material into the atmosphere in any one day from any article, machine, equipment or other contrivance used under conditions other than described in section (a), for employing, applying, evaporating or drying any photochemically reactive solvent, as defined in section (k), or material containing such solvent, unless all organic materials discharged from such article, machine, equipment or other contrivance have been reduced either by at least 85 per cent overall or to not more than 40 pounds in any one day.

c. Any series of articles, machines, equipment or other contrivances designed for processing a continuously moving sheet, web, strip or wire which is subjected to any combination of operations described in sections (a) or (b) involving any photochemically reactive solvent, as defined in section (k), or material containing such solvent, shall be subject to compliance with section (b).' Where only non-photochemically reactive solvents or material containing only non-photochemically reactive solvents are employed or applied, and where any portion or portions of said series of articles, machines, equipment or other contrivances involves operations described in section (a), said portions shall be collectively subject to compliance with section (a).
