Gego, E., A. GILLILAND, J. M. GODOWITCH, S. RAO, P. Porter, AND C. Hogrefe. Modeling Analyses of the Effects of Changes in Nitrogen Oxides Emission from the Electric Power Sector on Ozone Levels in the Eastern United States. JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION. Air & Waste Management Association, Pittsburgh, PA, 58(4):580-588, (2008).

Description:

This modeling study tests a hypothetical scenario to see what air quality might have looked like if no emission controls had been placed on electric generating units, as required by the NOx State Implementation Plan (SIP) Call required in 2004. Results showed that ozone levels would have been higher and air quality deteriorated noticeably if the controls had not been put in place.

Purpose/Objective:

The National Exposure Research Laboratory′s (NERL′s) Atmospheric Modeling Division (AMD) conducts research in support of EPA′s mission to protect human health and the environment. AMD′s research program is engaged in developing and evaluating predictive atmospheric models on all spatial and temporal scales for forecasting the Nation′s air quality and for assessing changes in air quality and air pollutant exposures, as affected by changes in ecosystem management and regulatory decisions. AMD is responsible for providing a sound scientific and technical basis for regulatory policies based on air quality models to improve ambient air quality. The models developed by AMD are being used by EPA, NOAA, and the air pollution community in understanding and forecasting not only the magnitude of the air pollution problem, but also in developing emission control policies and regulations for air quality improvements..
