The original intent of this study was to obtain air pollution emissions data that would help the U.S. Environmental Protection Agency establish National Emission Standards for municipal incinerators processing greater than 50 tons per day in accordance with the Clean Air Act of 1970, as amended. In March, 1971, the Office of Solid Waste Management Programs (OSWMP) requested that the Town of Braintree allow it to test the facility for this purpose. However, OSWMP was not able to conduct any tests on the incinerator until July, 1972 because it had not been formally accepted by the town until September, 1971. By this time the National Emission Standards had already been established. Since the incinerator is a modern plant equipped with high-efficiency air pollution control equipment, data obtained from the tests can be used for possible substantiation of the standards.
