• September 16, 2009 meeting between DOE and the American Petroleum Institute’s (API’s) Mid

- Level Ethanol Blends Research Coordination Group . API further discussed the continued uncertaint y regarding how test data on the compatibility of exiting retail fuel equipment with E15 might be used to help sat isfy Authorities who Have Jurisdiction ( AHJ ) , Occupational Safet y and Health ( OSHA ) , insurance, and other authorities concerns in the absence of a Underwriter’s Laboratories ( UL ) cert ification which is no rmally required. API discussed their plans to evaluate the compatibility of in

- use Stage I vapor recovery equipment, storage tanks, an d flame arrestors with E15. API also discussed their plans to evaluate potential measures to prevent mi sfueling equipment that may

not be tolerant of E15 if a partial waiver for E15 is granted. APIcontacted OSHA regarding whether OSHA might be able to accept something other than a UL certification to satisfy their requirements for fuel retail equipment.5

• Update on testing of materials used in retail dispenser equipment for compatibility

with mid

• Marathon’s decision to discontinue sales of E85. D OE/Marathon evaluation of potential safet y concerns with E85 blends containing 68% ethanol. Implications if butane blending is needed to meet minimum ASTM volatilit y specifications for E85. Pote nt ial to reduce to the minimum ethanol concentration of e thanol in E85 below 68%. Potential n eed for judgement b y DOE/FTC that this would be necessary /appropriate. October 14 , 2009 Conference Call: Participants: Kristi Moriarty , National Renewable Energy L aboratory

• Underground storage tank sy stem mid

- level blends compatibility testing plans
• Update on testing of materials used in retail dispenser equipment for compatibility

with mid

- level ethanol blends
• ASTM plans to ballot a change to minimum ethanol specification in ASTM E85 standard. Current ballot would adjust minimum ethanol specification from 70% to 68%. A further adjustment to a lower minimum ethanol concentration is expected to be discussed at the upcomin g ASTM meeting in December.6

• Update on testing of materials used in retail dispenser equipment for compatibility

with mid

- level ethanol blen ds
• Potential impacts on emissions and equipment durability of misfueling non

- flex fuel vehicles with E85 . DOE related that wrt the short term effects, the vehicle can be hard to start and the on

- board diagnostics code for misfire or fuel trim may be act ivated. In the long term, fuel level senders and fuel pumps could experience reduced durability . Some catal ys t failures were experienced at high speed when the fuel pump started to loose flow capacit y.
• Results of International Code Council (I C C) Asso ciation meeting regarding changes to the International al Fire Code (IFC) were discussed

. The i ndustry proposal to allow something other than standards body listing to suffice for retail fuel dispensing/storage equipment failed. Thus, if a waiver is granted for a mid

level ethanol blend, Authorities who Have Jurisdiction (AHJs) would need to grant a waiver of the (IFC) requirement in order for existing retail fuel handling equipment (originally

certified for E10) to be used for a mid

- level ethanol blend.
• Interaction of Energy Policy Act ( EPACT ) definition of an alternative fuel with ASTM minimum ethanol specification for E85. The Department of Energy (DOE) interprets the definition of an alternative fuel as specified under the EPACT. The current ASTM International ballot regarding the minimum ethanol concentration for E85 would adjust the minimum ethanol concentration to 68% from the current specification of 70% to assist in meeting the minimum volatility specification for E85. This proposed change wo uld be consistent with the minimum ethanol concentration for to meet the definition of an alternative fuel under the EPACT as interpreted b y DOE. If it is determined the ASTM minimum ethanol specification needs to be further reduced, the n the resulting fu el may fall outside of the definition of an alternative fuel a s defined by the EPACT and may not benefit from the requirements regarding the use of alternative fuel b y fleets as provided in the EPACT.
