View Rule

Under the Toxic Substances Control Act (TSCA), EPA has the authority to apply a suite of regulatory tools to address unreasonable risks from chemical substances, including authority to regulate the distribution in commerce for a particular use and to regulate any manner or method of commercial use, to the extent necessary so that the chemical substance no longer presents unreasonable risk. On January 19, 2017, EPA preliminarily determined that the use of 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 issued an advance notice of proposed rulemaking on March 27, 2019, to solicit public input on a training, certification, and limited access program to address unreasonable risks that may be presented by methylene chloride when used for commercial paint and coating removal. Such a program could allow access to paint and coating removal products containing methylene chloride only to commercial users who are certified as properly trained to engage in use practices that do not present unreasonable risks.
