EPA Includes More Than 30 Uses in the Draft Risk Evaluation for NMP

Lynn L. Bergeson Carla N. Hutton

On November 4, 2019, the U.S. Environmental Protection Agency (EPA) announced the availability of the draft risk evaluation for N-methylpyrrolidone (NMP), which includes more than 30 uses of NMP in adhesives, sealants, paints and arts and craft paints, paint and coating removers, adhesive removers, and degreasers.  EPA’s draft risk evaluation findings include:

  • EPA did not find risk to the environment, bystanders, or occupational non-users.  For all the conditions of use included in the draft risk evaluation, EPA has preliminarily found no unreasonable risks to the environment, bystanders, or occupational non-users from NMP.
  • EPA’s draft risk evaluation preliminarily found unreasonable risks associated with acute and chronic inhalation and dermal exposure to NMP under a variety of conditions of use.  EPA found that workers and consumers could be adversely affected by NMP under certain conditions of use.

EPA notes that these initial determinations are based on a draft risk evaluation of the reasonably available information and are not EPA’s final determinations on whether NMP presents unreasonable risks under the conditions of use.  EPA will publish a Federal Register notice announcing the availability of the draft risk evaluation and beginning a 60-day comment period.  The draft risk evaluation will be peer reviewed by the Toxic Substances Control Act (TSCA) Science Advisory Committee on Chemicals (SACC) on December 5-6, 2019.  EPA requests comments on the draft risk evaluation by November 26, 2019, to allow SACC time to review and consider them before the peer review meeting.  EPA states that it will use feedback received from the public comment and peer review processes to inform the final risk determinations.  More information will be available in our forthcoming memorandum.
