The U.S. Environmental Protection Agency (EPA) released on March 20, 2019, a list of 20 chemicals that EPA has suggested as candidates for high priority designation under the Toxic Substances Control Act (TSCA), as reported in our March 22, 2019, memorandum "EPA Releases List of 40 Chemicals Undergoing Prioritization for Risk Evaluation." Should those chemicals go forward as high priority, they will be subject to risk evaluation under TSCA Section 6. Industry stakeholder responses to this candidate list proposal and follow up actions with EPA related to risk evaluation work optimally will be conducted under existing or potentially newly formed chemical consortia. But what if your chemical is not on the list of 20? If you want to protect or even increase your business market advantage, consider inviting your commercial rivals to join an industry advocacy group anyway. This is particularly important if you have a chemical of commercial interest on the TSCA Work Plan Chemicals list. For more information on this issue, please see our full memorandum.
