EPA Releases Information that States and Tribes Can Use to Protect Local Fish
from Toxic Tire Chemicals
WASHINGTON – Today, June 10, the U.S. Environmental Protection Agency
published water quality screening values under the Clean Water Act related to
short-term concentrations of 6PPD and 6PPD-quinone (6PPD-q). These chemicals
have been found in freshwater ecosystems and linked to runoff from automotive
tire dust and debris. Once in freshwater, these chemicals are known toxins
that can quickly cause fish-kill events. The EPA’s non-regulatory and
non-binding screening values provide information that Tribes, states, and
local governments can use to monitor their waterways and help protect aquatic
life from these harmful pollutants.
“Achieving clean water that protects aquatic life and supports commercial,
recreational, and cultural fishing practices takes partnership at all levels
of government,” said EPA Acting Assistant Administrator for Water Bruno
Pigott. “6PPD and 6PPD-q can be lethal to fish, so it’s important we know
where it’s polluting waterways. The EPA’s screening values provide
important information that our partners can use to protect fish
populations—especially coho salmon on the Pacific coast. Solutions like
stormwater treatment and green infrastructure are effective at reducing
concentrations of these chemicals in freshwater ecosystems.”
This is the latest in a series of EPA actions to better understand and reduce
freshwater aquatic life exposure to these harmful chemicals. In November 2023,
the agency committed to consider establishing regulations prohibiting the
manufacturing, processing, use and distribution of 6PPD in tires and also
announced its intent to publish an advanced notice of proposed rulemaking
under the Toxic Substances Control Act (TSCA). The EPA also announced plans to
finalize a rule to require manufacturers (including importers) of 6PPD to
report lists and copies of unpublished health and safety studies to the
agency. In January 2024, the EPA announced the publication of a draft testing
method to help Tribes, states, and key stakeholders determine where and when
6PPD-q is present in local stormwater and surface waters. In March 2024, the
agency announced investments in the state of Washington to help treat and
control stormwater runoff that can contain 6PPD and 6PPD-q.
The EPA’s screening values are based on the latest scientific knowledge
about the short-term toxicity of 6PPD and 6PPD-q to freshwater aquatic life.
Based on current science, the agency believes that concentrations of 6PPD and
6PPD-q at or below these screening values are likely to protect freshwater
aquatic life. The EPA’s recommended screening values are not regulations and
they do not impose any legally binding requirements.

work on 6PPD-q.
