__________
a The denaturant must meet the ASTM D 4806-88
						specification for denatured fuel ethanol, except the denaturant cannot be
						rubber hydrocarbon solvent. The final blend specifications for E-85 take
						precedence over the ASTM D 4806-88 specifications.
b Hydrocarbon fraction shall have a final maximum boiling
						point of 225 degrees C by ASTM method D 86-90, oxidation stability of 240
						minutes by ASTM test method D 525-88 and No. 1 maximum copper strip corrosion
						by ASTM method D 130-88. Ethers must be aliphatic. No manganese added.
						Adjustment of RVP must be performed using common blending components from the
						gasoline stream. Starting 4/1/96, the hydrocarbon fraction must also meet
						specification for benzene, olefin content, aromatic hydrocarbon content,
						maximum T90 and maximum T50 found in California Code of Regulations, Title 13
						sections 2262.3,
						2262.4,
						2262.7 and
						2262.6 (T90 & T50),
						respectively.
c RVP range of 6.5 to 8.7 for those geographical areas
						and times indicated for A, A/B, B/A and B volatility class fuels in Table 2 of
						ASTM D 4814-91b. RVP range of 7.3 to 9.4 for those geographical areas and times
						indicated for B/C, C/B, C, C/D and D/C volatility fuels. RVP range of 8.7 to
						10.2 for those geographical areas and times indicated for D, D/E, E/D and E
						volatility fuels. Geographical areas referenced in this note shall be adjusted
						to reflect the air basin boundaries set forth in Title 17, California Code of
						Regulations, section
						60100 through
						60113.
d No added lead.
e No added phosphorus.
