California’s Office of Environmental Health Hazard Assessment (OEHHA) has extended its public comment period for a controversial proposed listing for an authoritative bodies listing under Proposition 65.
OEHHA announced its intent to list styrene as a carcinogen cancer via the authoritative bodies listing mechanism of Proposition 65 on February 27. Styrene is used in the manufacture of various consumer products, including polystyrene packaging, synthetic rubber and food containers.
OEHHA’s two attempts to list styrene as a carcinogen have both failed, but have also resulted in a noteworthy appellate opinion that clarified the mysterious Labor Code listing mechanism.
OEHHA’s latest attempt to list styrene was prompted by the findings of the National Toxicology Program’s (NTP’s) 2011 Report on Carcinogens which concluded that styrene is “reasonably anticipated to be a human carcinogen”
NTP’s listing of styrene in the 11th Report on Carcinogens was challenged by the Styrene Information and Research Center (SIRC)—the organization that successfully challenged OEHHA’s initial listing of styrene.
The outcome of SIRC’s challenge to NTP’s listing was rejected by a federal district court judge in 2013. The National Academy of Sciences confirmed NTP’s findings in its 2014 review of NTP’s styrene assessment.
OEHHA extended the public comment period because it received a request from the Expanded Polystyrene (EPS) Industry Alliance seeking an extension of time.
The extended comment period is open through the close of business on April 29.
