Discussion Items:

•	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 uncertainty regarding how test data on
the 

compatibility of exiting retail fuel equipment with E15 might be used to
help satisfy Authorities who Have Jurisdiction (AHJ), Occupational
Safety and Health (OSHA), insurance, and other authorities concerns in
the absence of a Underwriter’s Laboratories (UL) certification which
is normally required.   API discussed their plans to evaluate the
compatibility of in-use Stage I vapor recovery equipment, storage tanks,
and flame arrestors with E15.  API also discussed their plans to
evaluate potential measures to prevent misfueling equipment that may not
be tolerant of E15 if a partial waiver for E15 is granted.   API
contacted OSHA regarding whether OSHA might be able to accept something
other than a UL certification to satisfy their requirements for fuel
retail equipment.

Discussion Items:

•	Underground storage tank leak detection protocols

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

compatibility with mid-level ethanol blends

•	Marathon’s decision to discontinue sales of E85.  DOE/Marathon 
evaluation of 

potential safety concerns with E85 blends containing 68% ethanol. 
Implications 

if butane blending is needed to meet minimum ASTM volatility
specifications for E85.  Potential to reduce to the minimum ethanol
concentration of ethanol in E85 below 68%.  Potential need for judgement
by DOE/FTC that this would be necessary/appropriate.

October 14, 2009 Conference Call:

Participants:

Kristi Moriarty, National Renewable Energy Laboratory (NREL)

Tim Theiss, Oakridge National Laboratory (ORNL)

Marc Goodman, Department of Energy (DOE)

Douglas Horne, Clean Vehicle Education Foundation (CVEF)

Clare Kammer, Underwriters Laboratories (UL)

Andrea Barbery, EPA, Office of Underground Storage Tanks (OUST)

Jeff Herzog, EPA, Office of Transportation and Air Quality (OTAQ)

Discussion Items:

•	Underground storage tank system 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 upcoming ASTM
meeting in December. 

October 28, 2009 Conference Call:

Participants:

Kristi Moriarty, National Renewable Energy Laboratory (NREL)

Tim Theiss, Oakridge National Laboratory (ORNL)

Marc Goodman, Department of Energy (DOE)

Douglas Horne, Clean Vehicle Education Foundation (CVEF)

Joseph Sopata, EPA, Office of Transportation and Air Quality (OTAQ)

Jeff Herzog, EPA, (OTAQ)

Discussion Items:

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

compatibility with mid-level ethanol blends

•	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 activated.  In the long
term, fuel level senders and fuel pumps could experience reduced
durability.  Some catalyst failures were experienced at high speed when
the fuel pump started to loose flow capacity. 

•	 Results of International Code Council (ICC) Association meeting
regarding changes to the International al Fire Code (IFC) were
discussed.  The industry 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 would be consistent with the minimum ethanol
concentration for to meet the definition of an alternative fuel under
the EPACT as interpreted by DOE.  If it is determined the ASTM minimum
ethanol specification needs to be further reduced, then the resulting
fuel may fall outside of the definition of an alternative fuel as
defined by the EPACT and may not benefit from the requirements regarding
the use of alternative fuel by fleets as provided in the EPACT.
