EPA Releases Updated Systematic Review Supplemental Files for CI PV29 Risk Evaluation; Reopens Comment Period
On April 17, 2019, the U.S. Environmental Protection Agency (EPA) announced the availability of updated systematic review supplemental files with data evaluation scoring sheets as supporting documents for the draft risk evaluation for Colour Index (C. I.) Pigment Violet 29 (PV29) under the Toxic Substances Control Act (TSCA). 84 Fed. Reg. 16011. EPA states it is “seeking public comment on the draft risk evaluation for PV29 in light of the additional materials already made or being made publicly available.” In her April 16, 2019, blog item, Alexandra Dapolito Dunn, Assistant Administrator, EPA Office of Chemical Safety and Pollution Prevention, described the updated systematic review documents for PV29 as “a tool that guides our review and selection of scientific studies used to evaluate chemicals,” and that the updates were made “based on public input we received during the initial comment period.”
On March 22, 2019, EPA made 24 full study reports on PV29 available to the public, in some instances with information withheld as confidential business information (CBI) pursuant to EPA regulations. EPA has considered these materials in the risk evaluation process of PV29 and has also submitted these materials to the TSCA Science Advisory Committee on Chemicals (SACC). EPA states that comments submitted will be considered by the agency and also provided to the TSCA SACC peer review panel, which will have the opportunity to consider the comments during its discussions.
The comment period for the draft risk evaluation of CI PV29 closed on January 14, 2019, but via this notice is being extended. The Federal Register notice announcing the availability of the updated systematic review supplemental files lists a comment deadline of the same date as the notice -- April 17, 2019, but Docket ID EPA-HQ-OPPT-2018-0604-0038, however, lists a comment deadline of May 17, 2019; it is most likely that the docket is correct in this instance especially considering that follows what was stated by Ms. Dunn in her blog item that in light of the new and updated information EPA has recently released, "we will be reopening the public comment on the draft risk evaluation for PV29. It is important that the public have the opportunity to provide input on all of the information EPA is considering before our risk evaluation is finalized, so we invite you to provide us with your feedback. The public comment period will reopen for 30 days following publication in the Federal Register.”
