The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on November 7, 2019, announcing the availability of the draft risk evaluation for N-methylpyrrolidone (NMP) and soliciting public comment.  84 Fed. Reg. 60087.  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.

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 will hold a preparatory virtual meeting on November 12, 2019.  Stakeholders must register online on or before November 12, 2019, to receive the webcast meeting link and audio teleconference information.  Written comments for the preparatory virtual meeting and requests for time to present oral comments are due on or before 10:00 a.m. (EST) on November 12, 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.  Comments on the draft risk evaluation are due January 6, 2020.  More information is available in our November 5, 2019, memorandum, “EPA Releases Draft Risk Evaluation for NMP, Schedules SACC Review for December.”

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.

On May 1, 2017, the U.S. Environmental Protection Agency (EPA) issued a notice in the Federal Register stating it was reopening and extending the comment period for two proposed rules:  (1) to prohibit the use of trichloroethylene (TCE) in vapor degreasing; to require manufacturers (including importers), processors, and distributors, except for retailers, of TCE for any use to provide downstream notification of these prohibitions throughout the supply chain; and to require limited recordkeeping (issued January 19, 2017); and (2) to prohibit the manufacture (including import), processing, and distribution in commerce of methylene chloride and N-methylpyrrolidone (NMP) for consumer and most types of commercial paint and coating removal; to prohibit the use of methylene chloride and NMP in these commercial uses; to require manufacturers (including importers), processors, and distributors, except for retailers, of methylene chloride and NMP for any use to provide downstream notification of these prohibitions throughout the supply chain; and to require recordkeeping (issued January 19, 2017).  82 Fed. Reg. 20310.

This is the second extension of the comment period for the proposed rule to ban TCE use in vapor degreasing and the first extension of the comment period for the proposed rule to ban the uses of NMP and methylene chloride for consumer and most types of commercial paint and coating removal.  Comments on both proposed rules are now due on May 19, 2017.
