Conclusions and recommendations for EPRI's program in supplementary environmental control systems

Two important facts set the stage for the discussions of supplementary environmental control systems (SECS) at the EPRI Workshop on this topic: time-variable emissions control systems, which define SECS broadly, have been used successfully for at least forty years; and present concern over the lack of clearly defined threshold values for air pollutant effects, and the emergence of secondary pollutants as the potentially more dangerous culprits in environmental health, have led to strong opposition to SECS on the part of governmental, regulatory, and environmentally-oriented people. Since the successful use of SECS is based on meeting the national air quality standards, the second points above directly challenge any mode of pollutant control other than continuous control with best available technology. The Workshop quite literally had no choice but to accept the judgments of judicial, legislative, and regulatory agencies that risks associated with environmental pollutants are to be minimized and often without reference to costs. It was concluded that SECS is an acceptable interim measure for air pollution control under specific circumstances only, and will be phased out for the most part by legislative and regulatory fiat. SECS may have some continuing usefulness as a supplement to emission control systems, such as episode control or to satisfy more stringent state and local standards, but these will be special cases and not a general practice. The time is right and the need is great for a detailed analysis of the costs of air pollution emissions control for representative utility networks or power pools using a variety of control options, including SECS. Recommendation of the Workshop are discussed.
