Concern for the potential health hazards of medical wastes grew in the 1980s after medical wastes were washing up on several east coast beaches. This prompted Congress to enact The MWTA of 1988. The MWTA was a two-year federal program in which EPA was required to promulgate regulations on management of medical waste. The Agency did so on March 24, 1989. The regulations for this two year program went into effect on June 24, 1989 in four states - New York, New Jersey, Connecticut, and Rhode Island and Puerto Rico. It expired in 1991.

EPA concluded from the information gathered during this period that the disease-causing potential of medical waste is greatest at the point of generation and naturally tapers off after that point. Thus, risk to the general public of disease caused by exposure to medical waste is likely to be much lower than risk for the healthcare workers.
