Assessing and Managing Chemicals under TSCA

Submitting Information on TSCA Work Plan Chemicals to Inform Prioritization and Risk Evaluation

With the publication of the Federal Register Notice announcing the Agency’s document, "A Working Approach for Identifying Potential Candidate Chemicals for Prioritization," EPA opened public dockets for the remaining chemicals on the 2014 TSCA Work Plan for Chemical Assessments that are not currently undergoing risk evaluation or being addressed as Persistent, Bioaccumulative, and Toxic (PBT) chemicals under TSCA section 6(h). The Agency is providing the public an opportunity to submit use, hazard, and exposure information on these chemicals.  EPA will use this data, and other information as appropriate, to help inform the prioritization and risk evaluation processes for these chemicals under the amended Toxic Substances Control Act (TSCA).

On March 20, 2019, EPA announced that it is initiating the prioritization process for 20 chemicals listed on the 2014 TSCA Work Plan. Dockets for those chemicals will close 90 days following publication of the Federal Register notice. The dockets for the remaining 53 chemicals on the TSCA Work Plan will remain open until December 1, 2019.

In addition to the 73 dockets for the remaining chemicals listed on the 2014 TSCA Work Plan for Chemical Assessments, EPA has opened a general docket for chemicals not listed on the 2014 TSCA Work Plan for Chemical Assessments. The purpose of the general docket is to allow the public to make suggestions on potential chemicals for prioritization and to provide information on use, hazard, and exposure in support of their suggestions.

On this page:


Submitting Information to Public Dockets

EPA is interested in the following information about each chemical:

  • Types of industrial, commercial or consumer use;
  • Types of products containing each chemical;
  • Types of articles containing each chemical; industry sectors that use each chemical;
  • Information on functional uses; discontinued uses or phased out uses;
  • Available hazard and toxicity information;
  • Regulatory actions from other federal or state authorities;
  • Exposure monitoring data;
  • Engineering controls used to reduce exposure;
  • Safety Data Sheets; and
  • Physical-chemical properties.

It is helpful, though not required, for EPA to receive information in a consistent format. Templates for similar types of information create efficiencies in the management, processing and review of the information. For example, the OECD has developed templates for information submission. View and consider following the OECD Harmonized Templates for Reporting Chemical Test Summaries.Exit At a minimum, please include the chemical name, submitter name, and contact information in your submission.
