Emissions Inventories are the basis for numerous efforts including trends analysis, regional, and local scale air
quality modeling, regulatory impact assessments, and human exposure modeling.
The Emissions Factors & Policy Applications Center (EFPAC) provides information about existing emission factors,
the revision of existing factors and the development of new factors from stationary point and non point sources.
The Emissions Modeling Clearinghouse (EMCH) has been designed to support and promote emission modeling activities
both internal and external to the EPA. Through this site the EPA intends to distribute emissions model input formatted
inventories based on the latest versions of its National Emission Inventory databases.
|Emissions Monitoring Knowledge Base
EPA's Monitoring Knowledge Base Site provides information about monitoring techniques for air pollution control. The monitoring information is
presented by industry type and by control technique.
