New TRI chemical for Reporting Year 2016: 1-bromopropane

Q: On October 2, 2014, the National Toxicology Program (NTP) released its 13th Report on Carcinogens (RoC), which outlines chemicals that may pose a hazard to human health by virtue of their carcinogenicity. Has EPA added any of the chemicals from the 13th RoC to the EPCRA §313 TRI toxic chemical list?

A: On November 23, 2015, EPA finalized a rule that added 1-bromopropane to the TRI list of reportable chemicals (80 FR 72906). EPA concluded that 1-bromopropane meets the EPCRA §313(d)(2)(B) statutory listing criteria because it is “reasonably expected to be a human carcinogen.” Because 1-bromopropane is classified as a carcinogen by the NTP, it will be subject to the lower 0.1% concentration level for the de minimis exemption. This final rule was effective on November 30, 2015, and applies for the reporting year beginning on January 1, 2016 (forms due July 1, 2017).
