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. Methylene chloride and N-methylpyrrolidone (NMP) are used in paint and coating removal in commercial processes and consumer products. In the August 2014 TSCA Work Plan Chemical Risk Assessment for methylene chloride and the March 2015 TSCA Work Plan Chemical Risk Assessment for NMP, EPA characterized risks from use of these chemicals in paint and coating removal. On January 19, 2017, EPA preliminarily determined that the use of NMP and methylene chloride in paint and coating removal poses an unreasonable risk of injury to health. EPA also proposed prohibitions and restrictions on the manufacture, processing, and distribution in commerce of methylene chloride for all consumer and most types of commercial paint and coating removal and on the use of methylene chloride in commercial paint and coating removal in specified sectors. EPA 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 35% 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% 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. Also in that proposal, EPA identified commercial furniture refinishing as an industry for which EPA would like more information before proposing regulations to address the risks presented by methylene chloride, and announced its intention to issue a separate proposal to address those risks. EPA held a public workshop on September 12, 2017, with representatives of Federal and State government agencies, industry professionals, furniture refinishing experts, non-government organizations, academic experts, and others to discuss the role of methylene chloride in furniture refinishing, work practices employed when using methylene chloride in furniture refinishing, potential alternatives, economic impacts, and other issues identified in EPA's January 2017 proposed rule.
