Announcement of Publication of the Final Public Health Goals for Benzo(A)Pyrene, Methoxychlor, and TCDD (Dioxin) In Drinking Water

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency announces the publication of the final technical support documents for the Public Health Goals (PHGs) for benzo(a)pyrene, methoxychlor, and TCDD (dioxin) in drinking water. The PHG for benzo(a)pyrene is established at 0.007 parts per billion (ppb), based on carcinogenic effects in rats and mice. The PHG for methoxychlor is established at 0.09 ppb, based on effects in male offspring of female mice treated with methoxychlor during pregnancy. The PHG for TCDD is established at 0.00005 parts per trillion (ppt), based on tumors in multiple sites in female rats.

2010 EPA
Hazardous Waste Management System; Identification and Listing of Hazardous Waste; Removal of Saccharin and Its Salts From the Lists of Hazardous Constituents, Hazardous Wastes, and Hazardous Substances

The Environmental Protection Agency (EPA or the Agency) is proposing to amend its regulations under the Resource Conservation and Recovery Act (RCRA) to remove saccharin and its salts from the lists of hazardous constituents and commercial chemical products, which are hazardous wastes when discarded or intended to be discarded. EPA is also proposing to amend the regulations under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to remove saccharin and its salts from the list of hazardous substances. This proposed rule is in response to a petition submitted to EPA by the Calorie Control Council (CCC), to remove saccharin and its salts from the above lists. EPA is proposing to grant CCC's petition based on a review of the evaluations conducted by key public health agencies concerning the carcinogenic and other potential toxicological effects of saccharin and its salts, as well as EPA’s own assessment of the waste generation and management information for saccharin and its salts, which demonstrate that saccharin and its salts do not meet the criteria in the hazardous waste regulations for remaining on EPA's lists of hazardous constituents, hazardous wastes, and hazardous substances.

NTP Information Cited
EPA believes that saccharin and its salts, based on the results of the latest reviews of the available scientific information performed by NTP and IARC, do not pose a present or potential risk of causing toxic, carcinogenic, mutagenic or teratogenic effects on humans or other life forms. (ROC)

Food Additives; Bisphenol A; Availability

The Food and Drug Administration (FDA) announces the availability of five documents related to FDA’s continuing assessment of Bisphenol A (BPA) and solicits public comments on the four documents prepared by FDA’s Center for Food Safety and Applied Nutrition (CFSAN). These documents do not represent an agency opinion or position on BPA, on which an interim update was recently provided. (See Rather, these documents provide perspectives and opinions that are being considered by FDA as it continues its safety assessment of BPA. This action will enable FDA to consider comments from the public in its assessment of BPA for food contact applications.
