<P> During the 1880s and 1890s, Congress directed USACE to prevent dumping and filling in the nation's harbors, and the program was vigorously enforced . Congress first addressed water pollution issues in the Rivers and Harbors Act of 1899, giving the Corps the authority to regulate most kinds of obstructions to navigation, including hazards resulting from effluents . Portions of this law remain in effect, including Section 13, the so - called Refuse Act . In 1910, USACE used the act to object to a proposed sewer in New York City, but a court ruled that pollution control was a matter left to the states alone .

Bixby, suggested that modern treatment facilities and prohibitions on dumping "should either be made compulsory or at least encouraged everywhere in the United States ." </P> <P> Some sections of the 1899 act have been superseded by various amendments, including the 1972 CWA, while other notable legislative predecessors include: </P> <Ul> <Li> Public Health Service Act of 1912 expanded the mission of the United States Public Health Service to study problems of sanitation, sewage and pollution . </Li> <Li> Oil Pollution Act of 1924 prohibited the intentional discharge of fuel oil into tidal waters and provided authorization for USACE to apprehend violators .
