The final rule, expected by the end of 2024, will require manufacturers and importers of 6PPD to turn over unpublished health and safety studies
The US Environmental Protection Agency (EPA) has begun the process of regulating 6PPD, a common chemical found in car tyres that was responsible for mysterious salmon deaths in the American Northwest in 2020. In response to a petition by three Native American tribes, the agency plans to finalise the rule by the end of 2024, and it will require manufacturers and importers of 6PPD to provide copies of unpublished health and safety studies to the EPA, among other things. There will be reporting requirements by tyre manufacturers and others with 90 days of publication.
