According to an announcement in the Friday, Nov. 26, 2010, Federal Register, the EPA is adding 16 chemicals to the list of toxic chemicals subject to reporting. These 16 chemicals have been classified by the National Toxicology Program in their Report on Carcinogens as "reasonably anticipated to be a human carcinogen." The EPA has determined that these 16 chemicals meet the EPCRA section 313(d)(2)(B) criteria because they can reasonably be anticipated to cause cancer in humans.
The effective date for all 16 chemicals is Jan. 11, 2011, meaning they would need to be included in 2011 reports.
This final rule contains no changes to the list of chemicals the EPA included in the proposed rule. The chemicals being added as individual chemical listings on the EPCRA section 313 list in this final rule are as follows:
The interesting one is Isoprene, which is formed endogenously in humans and is generally the major hydrocarbon in human breath. Concentrations in blood range from 15 to 70 nmol/L. Humans produce isoprene endogenously at a rate of 0.15 μmol/kg/h, equivalent to approximately 17 mg/day for a 150-lb person Based on estimated human intake of 15 to 20 m3 air per day, ambient air would contribute less than 0.45 to 0.6 mg/day to daily isoprene exposure.
This final rule is effective November 30, 2010, and shall apply for the reporting year beginning Jan. 1, 2011 (reports due July 1, 2012).
