MEMORANDUM

SUBJECT:	Heavy-Duty Hybrid Onboard Diagnostics

FROM:		Amy Kopin

TO:		The Docket

DATE:		July 25, 2011

	On February 24th, 2011 we held a meeting in Ann Arbor, MI with the
Hybrid Manufacturers Regulatory Collaboration (HMRC) to discuss concerns
raised by members of the HMRC regarding heavy-duty onboard diagnostic
(OBD) requirements and timing.  Concerns were raised during the comment
period for the heavy-duty greenhouse gas notice of proposed rulemaking
that heavy-duty hybrid applications may not be able to meet the 2013
heavy-duty OBD regulations that were published in the 2009 OBD Final
Rulemaking.,  Attendees are presented in the table below.
