EPA asked to change course on assessment of dioxin
Calvin M Dooley, President and CEO, American Chemistry Council.


WASHINGTON DC, US: The American Chemistry Council (ACC), a chemical industry group, is asking the Environmental Protection Agency (EPA) to change course on its assessment of the most potent form of dioxin. Such a move could further prolong completion of the assessment, which has been under way for more than 20 years.

On 20 December 2011, in a letter, ACC asked EPA to delay the release of its hazard assessment for 2,3,7,8-tetrachloro­dibenzo-p-dioxin (TCDD). This pollutant causes cancer and is linked to reproductive problems. The assessment will affect the extent of cleanups of chlorinated and brominated dioxins and furans and polychlorinated biphenyls, as well as the costs borne by polluters.

In light of the new law, the letter from Calvin M Dooley, President and CEO, American Chemistry Council asked Lisa P Jackson, Administrator, EPA to reverse course on an EPA strategy to finish the long-pending document by splitting it into two parts. The agency plans to issue later this month a section on adverse non cancer health effects, such as reproductive problems, from exposure to TCDD. A second, more scientifically complicated part of the assessment will examine the cancer hazards of TCDD exposure and will be released later. This bifurcated approach is counter to National Research Council’s recommendation that the agency’s chemical assessments evaluate all relevant health end points, said Dooley.
