SIP - SCAPCA - Section 6.16

SECTION 6.16 - MOTOR FUEL SPECIFICATIONS FOR OXYGENATED GASOLINE

A. Purpose. This section establishes motor fuel specifications for oxygenated gasoline in order to reduce wintertime carbon monoxide emissions from gasoline powered motor vehicles.

B. Applicability. This section applies to all blenders and to all retail sellers of oxygenated gasoline, intended as a final product for fueling of motor vehicles within the Spokane Control Area and supplied to purchasers within the Spokane Control Area, as defined in Chapter 173-492-070 of the Washington Administrative Code (WAC).

C. Definitions. Unless a different meaning is clearly required by context, words and phrases used in Section 6.16 shall have the following meaning:

D. Adoption of state regulation by reference. Except for Subsections 173-492-040(1) and (2), Chapter 173-492 WAC is hereby adopted by reference, to the extent that it applies to the Spokane Control Area.

E. Blend and retail sale requirements for gasoline with non-ethanol oxygenates. Gasoline shall contain the maximum allowable oxygenate for the control period, unless the oxygenated is ethanol.

F. Blend and retail sale requirements for gasoline with ethanol as an oxygenate. The following requirements shall apply:
G. Conformity blend and retail sale requirement for gasoline with ethanol as an oxygenate. Notwithstanding Subsection F., the following requirement shall apply after the applicable Metropolitan Planning Organization, Ecology, and the Authority determine, after consultation that, due solely to an exceedance of a forecast of vehicle miles traveled, a higher level of oxygen in gasoline than what is required in Subsection F., is necessary in order for the Transportation Plan or the Transportation Improvement Program to conform to the Implementation Plan or Maintenance Plan:
H. Contingency blend and retail sale requirements for gasoline with ethanol as an oxygenate. Notwithstanding Subsections F. or G., gasoline shall contain the maximum allowable oxygenate, as of the initial control period beginning after EPA makes any one of the following findings in Subsection H.1., H.1., or H.3., relative to the Spokane Carbon Monoxide Nonattainment Area, in conjunction with the finding in Subsection H.4.:
The maximum allowable oxygenate requirement shall remain in effect for the duration of the initial control period and all subsequent control periods until the Authority proposes and EPA determines that subsequent reductions in carbon monoxide emissions, achieved through other control measures or strategies, are sufficient to correct the referenced failure or violation. Upon such determination by EPA, the applicable oxygenate requirement by EPA, the applicable oxygenate requirement in Subsection F. or G. shall apply, as of the beginning of the control period immediately following the determination.

I. Test method. Compliance with requirements in this Section for oxygen in gasoline, including maximum allowable oxygenate, shall be determined by ASTM 4815-89; Determination of C1 and C2 Alcohols and MTBE in Gasoline by Gas Chromatography, or other test methods as approved by Ecology.
State effective: 7/6/95; EPA effective: 12/31//97
