MEMORANDUM


                              
SUBJECT:	Heavy-Duty Hybrid Onboard Diagnostics

FROM:		Amy Kopin

TO:		The Docket

DATE:		July 15, 2011


	
	On July 6th, 2011 we held a conference call with the California Air Resources Board (CARB) to discuss concerns raised by hybrid manufacturers, engine manufacturers, and related industry trade groups 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.[,]  Specifically, manufacturers have requested a delay of the application of HD OBD requirements for hybrid applications until 2020.  Attendees from the EPA and CARB are shown in the table below.
