Hawaii

Current Regulations: On September 20, 2004, Hawaii adopted new regulations requiring at least 85% of all gasoline contain 10 vol% ethanol beginning April 2, 2006. An exemption is allowed if competitively priced ethanol is not available, or in the case of undue hardship. See Hawaii Administrative Rules Title 15, Chapter 35. These regulations implement Section 486J-10 of the Hawaii Revised Statutes.

Hawaii Administrative Rules require automotive gasoline to conform to ASTM D 439-79, class C volatility only per 4-86-10(1), and diesel fuel to conform to ASTM D 975-78 per 4-86-10 (3). Standards are enforced by the HI Department of Agriculture, Quality Assurance Division, Measurement Standards Branch.

Legislature: Introduced in January 2006, HB 2246 and HB 2611 would extend the 10 vol% ethanol in gasoline compliance date from April 2, 2006 to April 2, 2008. HB 3044 and SB 3182 introduced in January 2006, would ban MTBE in gasoline, except for de minimis levels, effective 7/1/07. SB 3182 was amended and passed by the Senate on 3/7/06.

Introduced in January 2007, HB 186 would change the ethanol in gasoline mandate from 10 vol% to 2 vol% and SB 1630 would delete the ethanol mandate

HB 809, HB 950, SB 405, SB 524, and SB 1079 (all introduced in January 2009) would eliminate the ethanol mandate. Introduced in January 2009, HB 1325 would require that all ethanol be produced from sugarcane grown in Hawaii.

Introduced in January 2011, HB 333 would repeal the ethanol mandate on 6/30/12 unless there is ethanol produced in Hawaii from locally grown or sourced feedstocks. 

HB 2648, introduced in January 2012, would repeal the ethanol mandate on 7/1/12.  Introduced in January 2012, SB 2339 and SB 2653 would repeal the ethanol mandate.  SB 2431 and HB 2006, both introduced in January 2012, would allow E0 unless sufficient quantities of locally produced ethanol or biofuel crops are available.

Introduced in January 2013, SB 15 would change the ethanol mandate to a biofuel mandate (biofuels must be at least 10%, on a Btu basis, of a distributor's sales of liquid fuels for motor fuels).  SB 790 and HB 1400, both introduced in January 2013, would repeal the ethanol mandate.  Introduced in January 2013, SB 372 would require diesel fuel to contain no less than: 5% biodiesel by 2015, 10% by 2020, and 20% by 2025; and repeal the ethanol mandate.  SB 201 and HB 81, both introduced in January 2013, would allow E0 unless sufficient quantities of locally produced ethanol or biofuel crops are available.

SB 717 and HB 743, both introduced in January 2015, would repeal the 10% ethanol mandate for gasoline.  Amended SB 717 was passed by the Senate on 3/10/15; however, it would not be effective until 7/1/50.  Introduced in January 2015, SB 348 would require diesel to contain no less than: 5% biodiesel by 2016; 10% biodiesel by 2020; and 20% biodiesel by 2025.
