Draft October 1997 MOBILE6 Workshop Agenda

Many requests have been received for a more detailed agenda for the
second MOBILE6 Stakeholder Workshop, set for October 1-2, 1997. The
following is a DRAFT agenda for the workshop.  It divides the
presentations into morning and afternoon sessions for each of the two
days.  Some changes to this agenda may occur before the workshop,
however EPA anticipates that we will be able to hold fairly closely to
the topics and order provided below.

Afternoon session:

Outputs for MOBILE6 (structure, proposed changes)
**Nonroad modeling--Introduction and description of features
**NONROAD model demonstration

**EPA is currently developing a national emission inventory model for
nonroad equipment.  The model covers more than 80 types of
compression ignition (CI) and spark ignition (SI) engine categories,
including such items as lawnmowers, motorboats, portable generators,
construction equipment, and commercial marine vessels.  The model
estimates mass emissions of hydrocarbons (HC), carbon monoxide
(CO), nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter
(PM) and carbon dioxide (CO2), for specific states and counties, for
past and future years.  The model provides the user with a flexible tool
that can be applied to a wide variety of air quality modeling and planning
functions.
