California’s Appellate Court ruled that California’s Office of Environmental Health Hazard Assessment (OEHHA) went too far in basing Prop 65 listing as a “known” carcinogen on the basis of an IARC 2B (possibly carcinogenic to humans) classification for styrene and vinyl acetate.  Since Prop 65 represents a blacklist in not only California but also many other states and purchasers who use it for their toxics lists, this is a Big Deal.  Obviously for styrene and vinyl acetate (which are building blocks for major polymers) but also for other Prop 65 candidates and blacklisters.
