1,4-Dioxane

April 20, 2015 - EPA released the final TSCA Work Plan Chemical Problem Formulation and Initial Assessment for 1,4-Dioxane. The problem formulation and initial assessment examined likely exposure and hazard scenarios to workers and consumers in order to identify scenarios where further risk analysis may be necessary. The assessment found no risks to the general population from inhalation exposure and low risks to aquatic life. EPA plans to conduct additional risk analysis on potential worker and consumer exposures.

Announcements

March 23, 2015 - EPA released the final TSCA Work Plan Chemical Risk Assessment for N-Methylpyrrolidone (NMP) (PDF) (281 pp, 7.0 mb, About PDF). The NMP assessment identified acute and chronic health risks to people, particularly pregnant women and women of childbearing age, who who are exposed to paint and coating removal products containing high concentrations of NMP, but those risks could be minimized by using NMP-resistant gloves in well ventilated work areas to reduce exposure.


March 10, 2015 – In response to requests from the public, EPA extended the public comment period for the proposed Significant New Use Rule under TSCA on long-chain perfluoroalkyl carboxylate and perfluoroalkyl sulfonate chemical substances by 90 days. EPA expects the notice announcing this extension to be published in the Federal Register on March 16, 2015. Comments on the proposed rule were originally due March 23, 2015. Comments will now be due June 26, 2015.


January 8, 2015 – To protect consumers from serious health effects, EPA proposed a Significant New Use Rule under TSCA on toluene diisocyanates (TDI) and related compounds. EPA will accept public comments on the proposal for 60 days from the time of publication in the Federal Register.


June 25, 2014 – EPA released its final TSCA Work Plan Chemical Risk Assessment for Trichloroethylene (TCE) (PDF) (212 pp, 3.0 mb, About PDF), identifying health risks from exposure when used as a degreasing agent, a spot removal agent in dry-cleaning and as a spray arts fixative.

EPA is using a multi-pronged strategy to ensure the safety of chemicals, recognizing that the current chemicals management law, the Toxic Substances Control Act (TSCA), needs to be strengthened.

EPA’s three-part strategy for addressing potential risks from existing chemicals includes:

In September 2009, EPA issued Essential Principles for Reform of Chemicals Management Legislation to help inform efforts underway in Congress to reauthorize and significantly strengthen the effectiveness of TSCA.
