Section 6 of the Toxic Substances Control Act provides authority for the EPA to ban or restrict the manufacture (including import), processing, distribution in commerce, and use of chemicals, as well as any manner or method of disposal of chemicals. The EPA identified n-methylpyrrolidone (NMP) and methylene chloride for risk evaluation as part of its TSCA Work Plan for Chemical Assessments. NMP and methylene chloride are used in commercial processes and in consumer products in residential settings. 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, the EPA identified risks associated with commercial and consumer paint and varnish stripping uses. The EPA is initiating rulemaking under TSCA section 6 to address these risks, if the EPA finds that there is a reasonable basis to conclude that the risks to human health or the environment are unreasonable.
