On May 9, 2019, the U.S. Environmental Protection Agency (EPA) announced it will hold the first meeting of the Science Advisory Committee on Chemicals (SACC) under the Toxic Substances Control Act (TSCA), for Pigment Violet 29 (PV29), the first chemical of the initial ten chemicals undergoing review, on June 18-21, 2019, from 9:00 a.m. to 5:30 p.m. (EDT) at the Holiday Inn Rosslyn at Key Bridge, Rosslyn Ballroom, 1900 North Fort Myer Drive, Arlington, Virginia.  84 Fed. Reg. 20354.  The meeting may also be available via webcast.

EPA states that the purpose of the SACC meeting is for EPA “to get the independent review of the science underlying the PV29 risk assessment, including the hazard assessment, assessment of dose-response, exposure assessment, and risk characterization.”  Additionally, this meeting will include an orientation on TSCA and how EPA is evaluating chemicals in commerce as prescribed in amended TSCA.  EPA states that it will use the scientific advice, information, and recommendations from the SACC, as well as public comments, to inform the final risk evaluation.  Comments are still being collected on the PV29 risk assessment until May 17, 2019, in Docket No. EPA-HQ-OPPT-2018-0604 on www.regulations.gov.

More information about the June SACC meeting and peer review of PV29 is available on EPA’s website.

According to press reports, Nancy Beck, Ph.D., DABT has been hired as the Principal Deputy Assistant Administrator for the U.S. Environmental Protection Agency’s (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP).  Dr. Beck holds a doctorate in environmental health from the University of Washington.  For the past five years she served as the Senior Director for Regulatory Science Policy at the American Chemistry Council (ACC).  For a decade prior to ACC, she was an analyst within the White House’s Office of Management and Budget (OMB).

Despite Dr. Beck’s compelling credentials, the appointment has displeased some stakeholders.  Dr. Beck has been a staunch critic of how EPA conducts chemical risk assessments and its Integrated Risk Information System (IRIS).  President Trump is proposing to eliminate IRIS; it thus is unlikely that Dr. Beck would revive or rely upon it in implementing the recently revised Toxic Substances Control Act (TSCA).  Less than two months ago, Dr. Beck provided testimony before the Senate Homeland Security and Government Affairs Subcommittee on Regulatory Affairs and Federal Management calling for changes to EPA’s risk assessment processes.

On November 29, 2016,  the U.S. Environmental Protection Agency (EPA) announced the initial ten chemical substances on which risk evaluations will be conducted under Toxic Substances Control Act (TSCA) Section 6(b)(2)(A).  The chemicals, all of which were to be drawn from the TSCA Work Plan for Chemical Assessments, are:

1,4-dioxane
1-bromopropane
Trichloroethylene (TCE)
Carbon tetrachloride
Hexabromocyclododecane (HBCD)
Methylene chloride
Pigment violet 29
Perchloroethylene (PERC)
N-methyl-2-pyrrolidone (NMP)
Asbestos

EPA is required under TSCA Section 6(b)(2)(A) to announce the chemicals within 180 days of enactment, or by December 19, 2016.

Interestingly, several of the chemicals are the subject of Section 6 rules that are currently undergoing review by the Office of Management and Budget (OMB).  These include TCE, methylene chloride, and NMP.  Assuming that EPA continues with these rules (relying on the savings provision at TSCA Section 26(p)(3) to use the completed risk evaluations on these chemicals in taking the Section 6 actions), the inclusion of the chemicals on the list may suggest that EPA will broaden the risk evaluations to include other conditions of use beyond those in the completed risk assessments.
