"Evaporative Emissions of Gross Liquid Leakers in MOBILE6" 

Report Number   EPA420-R-01-024     (M6.EVP.009)
 
	The Office of Transportation and Air Quality, Assessment and 
Standards Division announces the release of "Evaporative Emissions of 
Gross Liquid Leakers in MOBILE6" for public information.  This document 
EPA420-R-01-024, also known as M6.EVP.009, is available at the MOBILE6 
section of the OTAQ Web Site (http://www.epa.gov/otaq/m6.htm).

	In six parallel documents (M6.EVP.001, M6.EVP.002, M6.EVP.004, 
M6.EVP.005, M6.EVP.006, and M6.EVP.008), EPA noted that a potentially 
significant portion of evaporative emissions (from the in-use fleet) 
may be the result of a small number of vehicles leaking liquid gasoline 
(rather than gasoline vapors).  This document describes EPA's approach 
(in MOBILE6) to estimating both the frequency of occurrence vehicles 
with these significant leaks of liquid gasoline and the magnitude of 
the emissions resulting from those leaks.

	This report was originally released (as a draft) in June 1999.  
This current version is the final revision of that draft.  This final 
revision incorporates suggestions and comments received from stakeholders 
during the 60-day review period and from peer reviewers.
