On November 26, 2010, EPA finalized a rule, which became effective on November 30, 2010, that adds 16 chemicals to the TRI list of reportable chemicals. This is the first TRI program chemical expansion in over a decade. Each chemical added has been classified as "reasonably anticipated to be a human carcinogen" by the National Toxicology Program in their Report on Carcinogens document. EPA has concluded, based on a review of available studies, that these 16 chemicals could cause cancer in humans and therefore meet the EPCRA section 313(d)(2)(B) statutory listing criteria. [Based on this finding, California is likely to add these chemicals to the Proposition 65 list of chemicals, assuming they are not already listed.]
Four of the chemicals are being added under the polycyclic aromatic compounds category. The PAC's category is deemed to be of special concern because PAC's are persistent, bioaccumulative, toxic 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 body.
The 16 chemicals are: 1-Amino-2,4-dibromoanthraquinone, 1,6-Dinitropyrene, 2,2-bis(Bromomethyl)-1,3-propanediol, 1,8-Dinitropyrene, Furan, 6-Nitrochrysene, Glycidol, 4-Nitropyrene, Isoprene, Methyleugenol, o-Nitroanisole, Nitromethane, Phenolphthalein, Tetrafluoroethylene, Tetranitromethane, Vinyl Fluoride,
