Section 661.221.3. Flammable and combustible liquids.

The International Fire Code, 2006 edition, published by the ICC, Chapter 34 and references contained therein, and NFPA 30, Flammable and Combustible Liquids Code, 2003 edition and references contained therein, are adopted by reference as the rules for transportation, storage, handling, and use of flammable and combustible liquids. In any case in which a provision of the IFC conflicts with a provision of NFPA 30, the IFC provision shall apply. Any refinery shall comply with the provisions of this rule and with any applicable provisions of 661—Chapter 201.

       (1)             Delete the definition of combustible liquid and insert in lieu thereof the following:

COMBUSTIBLE LIQUID. A liquid having a closed cup flash point at or above 100°F (38°C) and below 200°F (93°C). Combustible liquids shall be subdivided as follows:

Class II. Liquids having a closed cup flash point at or above 100°F (38°C) and below 140°F (60°C).

The category of combustible liquids does not include compressed gases or cryogenic fluids.

       (2)             Delete the definition of refinery and insert in lieu thereof the following:

REFINERY. A plant in which flammable or combustible liquids are produced on a commercial scale from crude petroleum, natural gasoline or other sources, or in which flammable or combustible liquids are used to produce on a commercial scale fuels intended for use in motor vehicles, whether or not those fuels are flammable or combustible liquids.
