Impact/Purpose:
Our main objective is to assess the exposure of selected ecosystems to specific atmospheric stressors. More precisely, we will analyze and interpret environmental quality (primarily atmospheric) data to document observable changes in environmental stressors that may be associated with legislatively-mandated emissions reductions.
Description:
The main goal of EPA's Atmospheric Ecosystem Stressor Pattern and Trend Analysis work is to analyze and interpret environmental quality data collected to document observable changes in environmental stressors that may be associated with emissions reductions required by various legislation (i.e., Clean Air Act Amendments of 1990 [CAAA], state implementation plans (SIP), and Clear Skies Presidential initiative). This effort focuses on the analysis of atmospheric stressor and trends, and the analysis of data quality.

Project Information:
Progress :Atmospheric stressors and trends:Several preliminary analyses by NERL LCB scientists have addressed airborne sulfur and nitrogen stressor concentrations, spatial distributions, and trends using concentration data collected at Clean Air Status and Trends (CASTNET) and the National Atmospheric Depositon Program (NADP) sites in the eastern United States between 1989 and 1995. Following on a 1997 peer panel's recommendation to publish our work, over 30 publications, manuscripts, and presentations have been produced. Published studies of CASTNET and NADP concentration data show strong declines of airborne concentrations of both SO2 and sulfates, but little change in nitrogen concentrations. Recent analyses of total deposition (dry and wet) data from CASTNET and NADP for the time period 1990-2000 have shown strong declines in total sulfur deposition (25-30%) in the eastern U.S. with little change in total nitrogen deposition. Total sulfur and nitrogen deposition in the west have shown little change for the period 1990 to 2000. These results are generally consistent with emissions trends over the same period, especially the CAAA-mandated Phase I controls on emissions from electric power generation that became effective in January of 1995. Analyses to date indicate that CAAA-mandated Phase I controls for sulfur emissions are working. Nitrogen emissions from non-regulated sources have contributed to the lack of decline in nitrogen since the Phase I controls were implemented.
Relevance :Results from this research improves understanding of selected impacts of pollutant emissions reductions mandated under the CAAA and other "control strategy" actions in terms of air quality, deposition and changes to affected ecosystems. This research provides input to OAR CAMD for their preparation of reports to Congress assessing the environmental effectiveness of EPA's Acid Rain Program, as well as input to biennial assessments required under the US-Canada Air Quality Agreement.
