View Rule

Section 6(a) of the Toxic Substances Control Act provides authority for EPA to ban or restrict the manufacture (including import), processing, distribution in commerce, and use of chemical substances, as well as any manner or method of disposal. Section 26(l)(4) of TSCA authorizes EPA to issue rules under TSCA section 6 for chemicals listed in the 2014 update to the TSCA Work Plan for Chemical Assessments for which EPA published completed risk assessments prior to June 22, 2016, consistent with the scope of the completed risk assessment and other applicable requirements of section 6. N-methylpyrrolidone (NMP) is used in paint and coating removal in commercial processes and consumer products. In the March 2015 TSCA Work Plan Chemical Risk Assessment for NMP, EPA characterized risks from use of this chemical in paint and coating removal. On January 19, 2017, EPA preliminarily determined that the use of NMP in paint and coating removal poses an unreasonable risk of injury to health. EPA also co-proposed two options for NMP in paint and coating removal. The first co-proposal would prohibit the manufacture, processing, and distribution in commerce of NMP for all consumer and most commercial paint and coating removal and the use of NMP for most commercial paint and coating removal. The second co-proposal would require commercial users of NMP for paint and coating removal to establish a worker protection program and not use paint and coating removal products that contain greater than 3 percent NMP by weight, with certain exceptions; and require processors of products containing NMP for paint and coating removal to reformulate products such that they do not exceed 35 percent NMP by weight, to identify gloves that provide effective protection for the formulation, and to provide warnings and instructions on any paint and coating removal products containing NMP. In the final rule for methylene chloride in consumer paint and coating removal (RIN 2070-AK07), EPA explained that the Agency was not finalizing the proposed regulation for NMP as part of that action. NMP use in paint and coating removal was incorporated into the risk evaluation currently being conducted under TSCA section 6(b).
