Description This publication provides an overview of proposed hazard criteria that will be used to conduct a 6PPD alternatives assessment. These hazard criteria are similar to the Safer Products for Washington criteria for safer, with three additions: 1) Alternatives must have data on acute aquatic toxicity to coho salmon and rainbow trout, as well as data on two other trophic levels; 2) alternatives must have data on the toxicity of transformation products after exposure to ozone; and 3) we will place a limit on the acute toxicity LC50 values allowed in the minimum criteria (>0.1 mg/L).

We originally published the 6PPD Hazard Criteria in June 2023. This version of the 6PPD Hazard Criteria is revised in response to public input received from June 14, 2023, to July 14, 2023.
