On July 6, 2011, EPA initiated a 60-day comment period on a preliminary human health risk assessment for the pesticide chlorpyrifos.  This preliminary risk assessment is part of EPA’s registration review program that ensures all registered pesticides continue to meet current safety standards for registration; that is, they will not cause unreasonable adverse effects when used according to label directions and precautions.  This assessment includes new research findings available since the agency’s last human health risk assessment for chlorpyrifos, completed in June 2000.  EPA is requesting comment on key areas of the preliminary risk assessment, including the limitations of assessing residential bystander inhalation exposure, the conversion of chlorpyrifos to the more toxic degradate chlorpyrifos oxon during drinking water treatment and distribution, the impact of alternative drinking water treatment processes on chlorpyrifos and the oxon in finished drinking water, and the appropriate Food Quality Protection Act (FQPA) safety factor to use in the final risk assessment.  Regarding the FQPA Safety Factor, the Agency is presenting assessments which reflect the retention of the 10X Safety Factor and a proposal to reduce the FQPA Safety Factor to 1X based on newly available information.  The chlorpyrifos preliminary human health risk assessment and a related Reader’s Guide is available on the chlorpyrifos registration review status Web page,

Following a BPA Action Plan announced in March 2010, the EPA is requesting public comment on possible toxicity testing and environmental sampling to study BPA’s potential environmental impacts. BPA has been shown to cause reproductive and developmental effects in animal studies. This action is part of Administrator Lisa P. Jackson’s comprehensive effort to strengthen EPA’s chemical management program and assure the safety of chemicals that Americans encounter in their daily lives.
BPA is used in the manufacture of a wide range of consumer and industrial products including food-can liners, hard polycarbonate plastics, epoxy paints and coatings, and thermal papers, including some cash register receipts. Releases of BPA to the environment exceed 1 million pounds per year.  “A number of concerns have been raised about the potential human health and environmental effects of BPA,” said Steve Owens, assistant administrator for EPA’s Office of Chemical Safety and Pollution Prevention. “The data collected under the testing EPA is considering would help EPA better understand and address the potential environmental impacts of BPA.” In January 2010 the U.S. Food and Drug Administration announced it would further examine potential human health effects and reduce exposure to BPA in the food supply, which represents the greatest source of exposure to people. EPA is working with FDA, Centers for Disease Control, and the National Institute of Environmental Health Sciences on research under way to better determine and evaluate the potential health consequences of BPA exposures. At the conclusion of that research, EPA will determine if additional actions may be needed to address human health concerns from non-food use exposures. EPA issued an action plan on BPA in March 2010 outlining possible steps the agency might take to address risks presented by BPA, including the testing discussed in today’s announcement. EPA’s BPA action plan is available at
