Increased public awareness on environmental noise has resulted in a need for a comprehensive guide for the abatement of noise emissions from electric power plants. The Edison Electric Institute, the principal organization of investor owned electric utilities, sponsored the development of the Electric Power Plant Environmental Noise Guide (Guide) which providing utility engineers, environmentalists, consultants and regulators with detailed information for predicting, evaluating measuring, specifying, and abating power plant noise emissions. The information used in the Guide was gathered from technical publications, standards, consultants' project files and EEI member companies, and represents the state-of-the-art of power plant noise data. The Guide contains information on the following topics: (a) a method for estimating expected community response to power plant emissions; (b) a method for making noise surveys; (c) relationships between noise emissions and significant design parameters of more than twenty types of power plant equipment; (d) properties of outdoor sound propagation, including the effects of local topography and meteorology; (e) a step-by-step procedure of predicting noise emissions from an existing or proposed power plant and a method for drawing noise contours of the yearly energy average A-weighted sound levels; (f) the effectiveness and relative costs of noise control treatments for major power plant equipment; (g) a methodology for ordering the potential environmental noise impact of major pieces of power plant equipment; and (h) information on consensus noise standard applicable to power equipment. The Guide was prepared for EEI by Bolt Beranek & Newman, Inc., under the direction of the EEI Environmental Noise Regulatory Task Force, and it is available from the Edison Electric Institute, 1140 Connecticut Avenue, Northwest Washington, DC 20036.
