California EPA’s Office of Environmental Health Hazard Assessment (OEHHA) has changed the basis for listing 1,2-dibromo-3-chloropropane (DBCP), an agricultural fumigant that persists in groundwater despite being banned from use by the U.S. Environmental Protection Agency in 1979. "Based on changes to certain federal regulations that affect the bases for the original listings, OEHHA has accordingly changed the bases for listing these chemicals," according to the agency. DBCP was originally added to the Prop. 65 list of chemicals known to the state to cause reproductive toxicity in 1987 under the Labor Code, and its listing date will remain the same. Another chemical subject to the notice is ethylene oxide, which is used to make the raw material (PET) in plastic bottles. See OEHHA Press Release, November 21, 2013.
