NONROAD Model Archives

This page contains archive files related to the EPA Draft NONROAD Model, such as prior versions of the model and technical documentation. The primary use of these older drafts is for comparative analyses by professional mobile source modelers, such as state air quality officials and consultants. For the latest public version of the model and guidance on what version to use for SIPs see the main NONROAD model web page.

NOTE: You will need Adobe Acrobat Reader, available as a free download, to view some of the files on this page. See EPA's PDF page to learn more about PDF, and for a link to the free Acrobat Reader.

EPA does not recommend use of the draft NONROAD model in official SIP submittals. It is expected that emission rates and activity levels predicted by the model will change, possibly substantially, after further data collection and analysis. See the May 1999 announcement for more information on possible changes.
