TSCA Work Plan Chemicals
August 28, 2014 – EPA released final TSCA Work Plan Chemical Risk Assessments for DCM, ATO, and HHCB. The DCM assessment identified health risks to workers and consumers who use these products, and to bystanders in workplaces and residences where DCM is used.
August 1, 2014 –EPA held an experts workshop on TCE alternatives and risk reduction approaches on July 29-30, 2014.

Toxic Substances Control Act (TSCA) Work Plan
As part of EPA’s chemical safety program, in March 2012 EPA identified a work plan of 83 chemicals for further assessment under the Toxic Substances Control Act (TSCA). Watch a video on the TSCA Risk Assessment Program.
How Were the TSCA Work Plan Chemicals Selected?
After gathering input from stakeholders, EPA developed criteria used for identifying chemicals for further assessment. The criteria focused on chemicals that meet one or more of the following factors:
- Potentially of concern to children’s health (for example, because of reproductive or developmental effects)
- Neurotoxic effects
- Persistent, Bioaccumulative, and Toxic (PBT)
- Probable or known carcinogens
- Used in children’s products
- Detected in biomonitoring programs
Using this process, EPA identified 83 chemicals in the TSCA Work Plan as candidates for risk assessment in the next several years, as they all scored high in this screening process based on their combined hazard, exposure, and persistence and bioaccumulation characteristics.
Read the TSCA Work Plan Chemicals Methods Document (39 pp., 1.0 mb.) About PDF for a detailed explanation of the approach the Agency used to identify these chemicals.
In identifying a smaller set of TSCA Work Plan Chemicals for work in any given year, EPA considers a number of factors:
- Whether the chemical was identified as a “high” ranking chemical.
- Whether the chemical reflects more than one of the factors used to first identify Work Plan Chemicals, chemicals that were identified as a potential concern for children’s health and also were persistent, bioaccumulative, and toxic) and whether each of the factors was covered by the set of chemicals. These factors included health and environmental hazards, children’s health, use in consumer products and dispersive uses, persistence and bioaccumulation, and detection in biomonitoring and environmental monitoring.
- Whether certain chemicals or groups of chemicals, would benefit from some preliminary work to assure that risk assessments are targeted and scoped appropriately and therefore, would best be addressed in an out year.
- Whether certain chemicals or groups of chemicals have previously been assessed and addressed by the Agency, so that risk assessment in later years may be more appropriate than in the earlier years of the work plan.
- Agency work load considerations, including scope and timing of work needed on specific chemicals, and existing commitments for assessment.
Will EPA Revise the TSCA Work Plan?
EPA’s TSCA Work Plan sets forth the chemicals EPA plans to assess in the coming years. EPA plans to keep updating the Work Plan over time as assessments are completed, and as new or updated information about Work Plan Chemicals becomes available.
Will EPA Consider Chemicals Not on the TSCA Work Plan?
Identification of chemicals as TSCA Work Plan Chemicals (39 pp., 1.0 mb.) About PDF) does not mean that EPA would not consider other chemicals for risk assessment and potential risk management action under TSCA and other statutes. EPA will consider other chemicals if warranted by available information.
EPA will also continue to use its TSCA information collection, testing, and subpoena authorities, including sections 4, 8, and 11(c) of TSCA, to develop needed information on additional chemicals that currently have less robust hazard or exposure data.
