The CEIDARS emission inventory liaisons are the main point of contact between the 35 Local Air Districts for criteria emission inventory related issues. There is also a liaison between CARB and the U.S. EPA who deals with issues related to the submittal of CEIDARS data to the National Emission Inventory.

This report covers the data for 1994 testing and the methodology was then applied to 1996 test data. Profiles from the 1996 testing were used for the MTBE fuel and were also used as part of the basis for constructing the organic gas profiles for EtOH (ethanol) 2% O (oxygenate) gasolines.
The methane fraction in catalyst exhaust was clearly seen to increase as exhaust THC decreased. This relationship, as seen in the MTBE gasolines, was also used to project yearly methane fractions for ethanol gasolines. All other exhaust compounds are renormalized. Organic gas profiles for all other emission categories vary only with fuel composition.
The 1996 test data, from which the MTBE and EtOH containing fuel profiles were derived (via the adjustments in 'ogexh04.doc') are shown in the documents, below (note, especially, Attachment A2):
Attachment A1 - Peer Review of Organic Gas Emission Profiles
