On April 6, 2010, EPA published a proposed rule to add 16 new chemicals to the TRI toxic chemical list (75 FR 17333). The chemicals that EPA is proposing to add have been classified as "reasonably anticipated to be a human carcinogen" by the National Toxicology Program (NTP) in their Report on Carcinogens. Based on a review of NTP's report, EPA believes that the 16 chemicals meet the EPCRA Section 313(d)(2)(B) statutory listing criteria, as they are reasonably anticipated to cause cancer in humans. Twelve of the new proposed chemicals would be listed individually, while four are being proposed for addition to the polycyclic aromatic compounds (PAC) category. The PAC category is of special concern because PACs are persistent, bioaccumulative, toxic (PBT) chemicals.
