MEMORANDUM

TO:  		Docket EPA-HQ-OAR-2010-0162

SUBJECT:	Economy-Wide Impacts of Heavy-Duty Truck Fuel Efficiency and
GHG Standards

EPA has undertaken an analysis of the economy-wide impacts of the
proposed heavy-duty truck fuel efficiency and GHG standards.  To
estimate the impacts of this proposal on U.S. Gross Domestic Product
(GDP) and personal consumption, EPA has used an economy-wide, computable
general equilibrium (CGE) model. The economy-wide model used in this
analysis is the Intertemporal General Equilibrium Model (IGEM).  The
detailed output from the IGEM model are included in the associated
spreadsheet.
