Exit EPA Disclaimer

These estimating tools should be used with discretion. Actual emissions from individual sources may vary considerably from values estimated by using emission and speciation factors. Source-specific emission test data are generally preferred, when available. EPA welcomes any emission data that would help improve the emissions estimating tools presented here.

Copies of the tools mentioned above are available from different sources and under differing conditions related to requester status (government agency, commercial entity, nonprofit organization, Freedom Of Information Act requestor, etc.).
