EPA Proposes Evaluation of Five Chemicals

The Environmental Protection Agency this week proposed fast-tracking health risk evaluations for five chemicals, including vinyl chloride (Law360, subscription).

What’s going on: “In a Federal Register notice … published Thursday, the EPA said it’s proposing to list vinyl chloride, acetaldehyde, acrylonitrile, benzenamine and 4,4′-methylenebis(2-chloroaniline), or MBOCA, as high-priority substances for risk evaluations under Section 6(b) of the Toxic Substances Control Act.”

  • If the proposed designations are finalized, the EPA will start risk evaluation of the chemicals. This is a process used to determine whether a substance presents an unreasonable health or environmental risk.
  • Risk evaluation is the second step, after prioritization and before risk management, in the EPA’s TSCA chemical review and regulation process.

The background: The proposal to fast-track the evaluation of the five chemicals is “part of the agency’s efforts to implement 2016 amendments to the TSCA.”
