Program Title: Utility Acid Precipitation Study Program To obtain a better understanding of the relationship between power plant emissions and environmental quality, some 30 electric utilities formed the Utility Acid Precipitation Study Program (UAPSP) in 1980. This group sponsored a network of precipitation chemistry monitoring stations designed to provide long-term, high quality data on the chemical composition of rainfall, primarily in the eastern U.S. At several sites, stations have been operated continuously since 1979. The Electric Power Research Institute's Sulfate Regional Experiment (SURE) network operated between 1979 and the end of 1980, and the Utility Acid Precipitation Study Program (UAPSP) network continued on from the beginning of 1981 until the end of 1987. At the beginning of 1988 the EPRI Operational Evaluation Network (OEN) began operations which continued into 1990. There were also several networks in other parts of the U.S. collecting daily precipitation chemistry data at about the same time as UAPSP, the major ones being MAP3S (Multistate Atmospheric Power Production Pollution Study), WISC (Wisconsin Acid Deposition Monitoring Network) and FADS (Florida Acid Deposition Study). UAPSP converted data from these networks into the standard UAPSP format, and included them in the database. See: "http://src.com/~epriasdc/uapsp/uapsp.htm" for information on the UAPSP program.
