PCTC joined with four other trade associations to submit comments to EPA for discussion at a June 29, 2016, Public Science Meeting convened by EPA’s Integrated Risk Information System (IRIS). For the Public Science Meeting, EPA has invited a group of scientists with expertise in skin cancer to discuss how the IRIS program can address the opinion of EPA’s Science Advisory Board (SAB) that the proposed skin cancer risk value proposed by the IRIS program for benzo(a)pyrene (BaP) “is not sufficiently supported scientifically.” EPA uses BaP as the index compound for the polycyclic aromatic hydrocarbon (PAH) category of chemical compounds. PCTC’s position is that materials containing mixtures of PAHs should be evaluated as whole products, not on the basis of individual chemical constituents such as BaP.
PCTC joined with the American Petroleum Institute (API), the American Coke & Coal Chemicals Institute (ACCCI), the Asphalt Institute, and the Association of American Railroads (AAR) to commission a review of EPA’s science questions, and submit comments based on the review. The comments are posted on EPA’s electronic docket, here, and are also available here.
PCTC has been partnering with API, ACCCI, AAR, the Asphalt Institute, and other trade associations to submit comments to EPA’s IRIS program on its draft assessments of PAH mixtures and BaP since 2010. Joint comments on the SAB review draft of the EPA/IRIS PAH mixtures document are available here. Joint comments on the public review draft of the EPA/IRIS BaP assessment document are available here.
