A controversy about the scientific credibility of results from the Community Health and Environmental Surveillance System (CHESS) study prompted a series of Congressional hearings in 1976 ('The Brown Report') with subsequent legislation (Public Law 95-155) to enact the Environmental Research, Development and Demonstration Authorization Act of 1978. This addendum has been compiled to satisfy Recommendation 3(c) of The Brown Committee Report, entitled 'The Environmental Protection Agency's Research Program with Primary Emphasis on the Community Health and Environmental Surveillance System (CHESS): An Investigative Report.' It contains the following materials which concern the 1974 CHESS Monograph and various CHESS studies, in addition to EPA's research and development program in general: as follows The Brown Committee Report; P.L. 95-155; Appendices from EPA's Research Outlook for 1978 and 1979; and the Science Advisory Board's Health Effects Research Review Group Report to Congress in February 1979.
