Since the 1980s, saccharin was included in EPA's lists of hazardous wastes, hazardous constituents, and hazardous substances because it was identified as potentially causing cancer in people. In the late 1990s, the National Toxicology Program and the International Agency for Research on Cancer re-evaluated the available scientific information on saccharin and its salts and concluded that saccharin and its salts are not potential human carcinogens. Because the scientific basis for remaining on EPA's lists no longer applies, the agency is issuing a proposed rule to remove saccharin and its salts from the list.
The public comment period will be open for 60 days after the proposal is published in the Federal Register.
