A.  EPA received a petition from the Calorie Control Council (CCC) to remove saccharin and its salts from the mentioned hazardous lists.  The CCC cited the removal of saccharin as a potential human carcinogen by the National Toxicology Program and International Agency for Research on Cancer as justification to remove saccharin and its salts from hazardous listings.

EPA reviewed the evaluations conducted by the National Toxicology Program and the International Agency for Research on Cancer concerning the carcinogenic and other potential toxicological effects of saccharin and its salts.  Based on the conclusions by these public health agencies that saccharin and its salts are not reasonably expected to be human carcinogens, as well as EPA’s own assessment of the waste generation and management information, EPA issued a proposed rule in April 2010 proposed granting CCC’s petition.

As no objections were received during the public comment period, EPA finalized the proposal on December 17, 2010.
