Description
OEHHA posted a request for relevant information on the carcinogenicity of ethoprop and indicated the substance is being referred to the Carcinogen Identification Committee (CIC) for review for possible delisting. This initiates a stakeholder input/data submission process that could ultimately lead to a delisting decision. Compliance teams using ethoprop in products or operations should monitor the review, consider submitting relevant toxicology/exposure data, and be prepared to adjust Prop 65 warning determinations if OEHHA proceeds with delisting or maintains the listing.
