Current Regulations: The Governor requested RFG opt-out and the RFG program in Lewiston-Auburn, Portland and Knox and Lincoln Counties ended effective March 10, 1999. Beginning with the summer of 1999, Maine required a summer max. 7.8 psi RVP gasoline in these areas. See 06-096 Code of Maine Rules, Chapter 119 Motor Vehicle Fuel Volatility Limit.

Signed by the Governor on 4/14/04, LD 1870 bans MTBE in gasoline effective 1/1/07; it also includes a de minimis level of 0.5 vol% MTBE. See Maine Revised Statutes, Title 38, Chapter 4, Section 585-I.

LD 1662 (SP 627), Public Law (Chapter 604) signed by the Governor on 4/5/10, lowers the maximum sulfur content for distillate fuel oil (except for manufacturing uses) to 0.005% by weight by 7/1/16 and 0.0015% by weight by 1/1/18, and for residual fuel oil to 0.5% by weight by 1/1/18; the bill also permits the application of an "equivalent alternative sulfur reduction strategy." See Chapter 106 of Maine's Rules for the Department of Environmental Protection (06-096). LD 603 (HP 416) delays the 15 ppm sulfur limit for distillate fuel oil by six months; enacted 5/10/15 without the governor's signature (Chapter 66 Public Law).  In addition, the distillate fuel oil sulfur standard for 7/1/16 was deleted. The 0.0015% by weight sulfur cap for distillate fuel oil sulfur beginning 7/1/18 is ME Revised Statutes, Title 38, Chapter 4, section 603-A(2)(A)(3).  

LD 115 (HP 97), Public Law 249, approved by the Governor on 6/14/13, prohibits motor fuel containing corn ethanol if 10 other states with a collective population of at least 30 million have the same law.

LD 1359 required RFG by 5/1/14 in York, Cumberland, Sagadahoc, Androscoggin, Kennebec, Knox and Lincoln Counties; passed by the House and Senate in May 2013 and became law (Chapter 221) without the governor's signature.  LD 1796 postpones the RFG effective date until 6/1/15; passed by the House and Senate on 2/27/14 and signed by the governor on 3/6/14 (Chapter 453).  This was provisionally adopted on 6/5/14 by Maine's Department of Environmental Protection. RFG was approved by EPA for these counties beginning in the summer of 2015 on 1/23/15 (published at 80 FR 6658; 2/6/15). 

In a multi-state letter dated 8/31/17, to address a fuel supply emergency caused by Hurricane Harvey, EPA waived RFG requirements and allowed 11.5 psi RVP gasoline throughout the state through September 15.  

Proposed State Actions: The Commissioner of the ME Department of Environmental Protection and representatives of ten other states signed a Letter of Intent, dated 12/31/08, to analyze low carbon fuel supply options and develop a framework for a regional Low Carbon Fuel Standard in the Northeast/Mid-Atlantic region. Governor Baldacci and the governors of 10 NE/MA states signed a Memorandum of Understanding dated 12/30/09 for the development of a regional LCFS.

Legislature: Introduced in March 2009, LD 1320 (SP 478) would require a retail dealer and distributor of gasoline to offer for sale or use nonethanol-blended unleaded premium grade gasoline.

LD 1632 (HP 1160), passed as amended by House on 3/11/10, would establish state goals and a biofuels study for 2% biofuel by 7/1/13 and 5% by 7/1/15 in all number 2 heating oil. 

Introduced in March 2015, LD 824 (HP 558) would clarify that a motor fuel distributor, franchisor or refiner may not impose any condition, restriction, agreement or understanding that prohibits or limits the sale, resale, transfer or purchase of conventional, ethanol-free motor fuel products in Maine; vetoed by the governor on 5/15/15.
