[Code of Federal Regulations] [Title 40, Volume 13] [Revised as of January 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR68.2] [Page 158-159] TITLE 40 - PROTECTION OF ENVIRONMENT CHAPTER I - ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 68 - CHEMICAL ACCIDENT PREVENTION PROVISIONS--Table of Contents Subpart A - General Sec. 68.2 Stayed provisions. (a) Notwithstanding any other provision of this part, the effectiveness of the following provisions is stayed from March 2, 1994 to December 22, 1997. (1) In Sec. 68.3, the definition of ``stationary source,'' to the extent that such definition includes naturally occurring hydrocarbon reservoirs or transportation subject to oversight or regulation under a state natural gas or hazardous liquid program for which the state has in effect a certification to DOT under 49 U.S.C. 60105; (2) Section 68.115(b)(2) of this part, to the extent that such provision requires an owner or operator to treat as a regulated flammable substance: (i) Gasoline, when in distribution or related storage for use as fuel for internal combustion engines; (ii) Naturally occurring hydrocarbon mixtures prior to entry into a petroleum refining process unit or a natural gas processing plant. Naturally occurring hydrocarbon mixtures include any of the following: condensate, crude oil, field gas, and produced water, each as defined in paragraph (b) of this section; (iii) Other mixtures that contain a regulated flammable substance and that do not have a National Fire Protection Association flammability hazard rating of 4, the definition of which is in the NFPA 704, Standard System for the Identification of the Fire Hazards of Materials, National Fire Protection Association, Quincy, MA, 1990, available from the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269-9101; and (3) Section 68.130(a). (b) From March 2, 1994 to December 22, 1997, the following definitions shall apply to the stayed provisions described in paragraph (a) of this section: Condensate means hydrocarbon liquid separated from natural gas that condenses because of changes in temperature, pressure, or both, and remains liquid at standard conditions. Crude oil means any naturally occurring, unrefined petroleum liquid. Field gas means gas extracted from a production well before the gas enters a natural gas processing plant. Natural gas processing plant means any processing site engaged in the extraction of natural gas liquids from field gas, fractionation of natural gas liquids to natural gas products, or both. A separator, dehydration unit, heater treater, sweetening unit, compressor, or similar equipment shall not be considered a ``processing site'' unless such equipment is physically located within a natural gas processing plant (gas plant) site. Petroleum refining process unit means a process unit used in an establishment primarily engaged in petroleum refining as defined in the Standard Industrial Classification code for petroleum refining (2911) and used for the following: Producing transportation fuels (such as gasoline, diesel fuels, and jet fuels), heating fuels (such as kerosene, fuel gas distillate, and fuel oils), or lubricants; separating petroleum; or separating, cracking, reacting, or reforming intermediate petroleum streams. Examples of such units include, but are [[Page 159]] not limited to, petroleum based solvent units, alkylation units, catalytic hydrotreating, catalytic hydrorefining, catalytic hydrocracking, catalytic reforming, catalytic cracking, crude distillation, lube oil processing, hydrogen production, isomerization, polymerization, thermal processes, and blending, sweetening, and treating processes. Petroleum refining process units include sulfur plants. Produced water means water extracted from the earth from an oil or natural gas production well, or that is separated from oil or natural gas after extraction. (c) Notwithstanding any other provision of this part, the effectiveness of part 68 is stayed from June 21, 1999 to December 21, 1999 with respect to regulated flammable hydrocarbon substances when the substance is intended for use as a fuel and does not exceed 67,000 pounds in a process that is not manufacturing the fuel, does not contain greater than a threshold quantity of another regulated substance, and is not collocated or interconnected to another covered process.
