Geographic Allocation and Growth In EPA's NONROAD Emission Inventory Model

摘要

The purpose of this paper is to discuss two critical input variables that are anticipated to be used in the final version of the EPA nonroad mobile source emissions model. The NONROAD model, as it is called, uses these inputs to geographically allocate national equipment population estimates to State or county modeling domains, and for projecting nonroad equipment populations and emissions for future years. This model will provide a tool for EPA, States, regional air pollution organizations, and local air pollution control agencies to use in estimating pollution from nonroad vehicles and equipment for State Implementation Plans (SIPs), as required by the 1990 Clean Air Act Amendments, and other regulatory needs.
