EPA/OCSPP RIN: 2070-AK46 Publication ID: Spring 2021 
Title: N-Methylpyrrolidone; Regulation of Certain Uses Under TSCA Section 6(a) 
Abstract: Section 6(a) of the Toxic Substances Control Act (TSCA) 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. 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. 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, and EPA took steps to continue considering regulation of the use of NPRM in paint and coating removal in a separate action (RIN 2007-AK46). The use of NMP in paint and coating removal was subsequently considered as part of the TSCA section 6(b) final risk evaluation for NMP, and EPA initiated a new action (RIN 2070-AK85) under TSCA section 6(a) to address the unreasonable risks of NMP. EPA announced the withdrawal of this proposed rule in the Federal Register of January 15, 2021.
