TRI chemicals added as a result of the 2005 Report on Carcinogens

In 2005, the National Toxicology Program (NTP) released its 11th Report on Carcinogens (RoC), which outlines chemicals that may pose a hazard to human health by virtue of their carcinogenity.  Has EPA added any of the chemicals from the RoC to the EPCRA §313 TRI toxic chemical list?

On November 26, 2010, EPA expanded the TRI toxic chemical list by adding 16 chemicals classified as “reasonably anticipated to be a human carcinogen” by the National Toxicology Program’s (NTP) Report on Carcinogens (75 FR 72727). After reviewing the NTP’s report, EPA believes that these 16 chemicals meet the EPCRA §313(d)(2)(B) statutory listing criteria because they can reasonably be anticipated to cause cancer in humans. Twelve of the chemicals were listed individually, while the remaining four were added to the polycyclic aromatic compounds (PACs) category. The PACs category is a category of special concern because PACs are persistent, bioaccumulative, toxic (PBT) chemicals, and as such, they are likely to remain in the environment for a very long time, are not readily destroyed, and may build up or accumulate in the body.

 

This rulemaking to expand the TRI toxic chemical list is a part of EPA’s ongoing efforts to provide communities with more complete information on chemicals. The revised toxic chemical list is effective starting with reports due July 1, 2012, for Reporting Year 2011.
