Scope of Pigment Violet 29 Risk Evaluation under Amended TSCA

This scope document includes the hazards, exposures, conditions of use, and the potentially exposed or susceptible subpopulations EPA expects to consider in its risk evaluation of pigment violet 29 conducted pursuant to TSCA Section 6(b)(4). EPA will publish and take public comment on a Problem Formulation document for pigment violet 29 which will refine the current scope, as an additional interim step, prior to publication the draft risk evaluation. This problem formulation is expected to be released within approximately six months of publication of the scope documents.
