The TSCA Interagency Testing Committee (ITC) submitted a report to EPA on April 13, 2020 listing an additional 39 chemicals on the priority testing list. Within the 39 chemicals, 15 are already designated as high-priority substances and 24 are organohalogen flame retardants. The priority testing list currently has five other high-priority substances and six organohalogen flame retardants. The high-priority substance list contains substances with the most demand for evaluation from a risk-based screening process.
ITC also recommended the 15 high-priority substances be added to TSCA section 8(d) Health and Safety Data Reporting rule in order for EPA to obtain unpublished health and safety studies. The report states the high-priority substances may present an unreasonable risk for the health of people and/or the environment. The risk evaluation process has already begun for each of these high-priority substances.
The 24 organohalogen flame retardants were added to the priority testing listing after the Consumer Product Safety Commission (CPSC) voted to ask the ITC to add the chemicals. In addition, CPSC granted a petition to begin rulemaking for additive, nonpolymeric organohalogen flame retardants under the Federal Hazardous Substances Act
EPA is currently seeking public comments on the revisions to the priority testing list and any information relevant to the listing. The comment period is open until May 28, 2021.
