摘要

Each year, the U.S. Environmental Protection Agency (EPA) develops emission estimates for the criteria pollutants for the entire U.S. in order to assess trends in these emissions. These annual emission estimates are developed for point, area, and mobile sources. Area sources are normally calculated using a variety of estimation procedures that are documented in the National Air Pollution Emission Trends, Procedures Document 1900-1996. The emission estimation procedures outlined in that document represent a number of related, but cumbersome estimation tools to derive either a "top-down" estimate or a county-level "bottom-up" emissions inventory for area sources. With promulgation of the revised ozone and particulate matter (PM) National Ambient Air Quality Standards (NAAQS), an area source emission estimation model that consolidates all of the methods used in producing the Trends emission estimates is highly desirable. This paper describes the goals, design, and development of an Area Source Emissions Model (ASEM). An alpha test version that provides estimates for a few categories has been completed and a beta version is currently under development. The beta test version is designed to combine the existing calculations being made to estimate area source emissions of PM_(2.5) and its most important precursors (ammonia [NH_3], nitrogen oxides [NO_x] and sulfur oxides [SO_2]) for Trends into a consolidated model with any easy to use user interface and report generator. This model will facilitate: 1) the use of consistent methodologies and the use of consistent activity data to estimate emissions from area sources and will enable the user to vary selected parameters and recalculate the emissions estimate for one or more categories; 2) ease of calculation when using location-specific data; and 3) development of summary outputs and exchange of the data among States and with the EPA. The paper discusses the alpha test version, plans for the beta test version, and a discussion of future plans for the model.
