Chem Makers to Submit Risk Info

Tuesday, June 5, 2012 @ 04:06 PM gHale

Chemical manufacturers that produce certain flame retardants, fragrances, and other chemicals should submit to the Environmental Protection Agency (EPA) bu Aug. 31 information on the risks the compounds pose.

Hazard data, exposure data, and other risk-relevant information developed by other organizations should also come in.

EPA released on June 1 a list of 18 chemicals 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The agency also asked interested parties to submit information, such as unpublished scientific studies not already available through the existing literature or information on uses and potential exposures, to the agency for the assessments.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 need to manage risks the chemicals might pose.

The chemicals and groups of chemicals are:
five chlorinated hydrocarbons:
• 1,1-dichloroethane;
• 1,2-dichloropropane;
• 1,2-dichloroethane;
• trans-1-2-dichloroethylene;
• 1,1,2-trichloroethane;

three flame retardants:
• bis (2-ethylhexyl)-3,4,5,6-tetrabromophthalate ;
• 2-ethylhexyl-2,3,4,5-tetrabromobenzoate;
• tris (2-chloroethyl)phosphate;

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)-;

six additional chemicals:
• 1-bromopropane;
• 4-tert-octylphenol;
• 4-sec-butyl-2,6-di-tert-butylphenol;
• 2,4,6-tri-tert-butylphenol;
• p,p’-oxybis (benzenesulfonyl hydrazide); and
• octamethylcyclotetrasiloxane (D4).

The 18 chemicals came from a list of 83 the agency released in March as candidates for risk assessment over the next several years.

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.

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, can transmit via
