EPA Assessments of Chemicals in Commerce
Key Development: Makers of 18 flame retardants, fragrances, and other chemicals are asked to submit information to EPA by Aug. 31 relevant to risks the compounds pose.
What's Next: The agency will use the submitted data and publicly available information in 2013 and 2014 to assess the risks of the chemicals.

Chemical manufacturers that produce certain flame retardants, fragrances, and other chemicals are being asked to submit to the Environmental Protection Agency by Aug. 31 information relevant to the risks the compounds pose.
Hazard data, exposure data, and other risk-relevant information that has been developed by other organizations also may be submitted.
EPA released on June 1 a list of 18 chemicals in commerce for which it plans to complete risk assessments in 2013 and 2014.
The agency also asked interested parties to submit information, such as unpublished scientific studies that are not already available through the existing literature or information on uses and potential exposures, to the agency for the assessments.
EPA would use the risk analyses for regulatory or other actions the agency may conclude are needed to manage risks the chemicals might pose.
The chemicals and groups of chemicals are:
five chlorinated hydrocarbons:
three flame retardants:
• bis(2-ethylhexyl)-3,4,5,6-tetrabromophthalate ;
four fragrance chemicals:
• ethanone, 1-(1,2,3,4,5,6,7,8-octahydro- 2,3,8,8-tetramethyl-2-naphthalenyl)-4-sec-butyl-2,6-di-tert-butylphenol;
• ethanone, 1-(1,2,3,4,5,6,7,8-octahydro- 2,3,5,5-tetramethyl-2-naphthalenyl)-;
• ethanone, 1-(1,2,3,5,6,7,8,8a-octahydro- 2,3,8,8-tetramethyl-2-naphthalenyl)-;
• ethanone, 1-(1,2,3,4,6,7,8,8a-octahydro- 2,3,8,8-tetramethyl-2-naphthalenyl)-;
and six additional chemicals:
• p,p'-oxybis(benzenesulfonyl hydrazide); and
• octamethylcyclotetrasiloxane (D4).
The 18 chemicals were drawn from a list of 83 the agency released in March as candidates for risk assessment over the next several years (41 DEN A-14, 3/2/12).
EPA selected the chemicals because they have potential characteristics such as persistence in the environment, accumulation in the food chain, and harmfulness to human health or the environment.
The June 1 announcement means EPA is assessing a total of 25 of the 83 chemicals, or about one-third of its “work plan” compounds.
Richard Denison, a senior scientist with the Environmental Defense Fund, told BNA the organization is pleased with the ambitious pace at which the agency is striving to assess these chemicals.
“The proof will be in the assessments, not just the identification of the chemicals,” he said.
Chemical manufacturers or other parties providing information to EPA should include the chemical name and Chemical Abstract Service number on their submission and mark the material with docket number EPA-HQ-OPPT-2011-0516.
The submissions, due Aug. 31, should be transmitted via http://www.regulations.gov.
