EPA releases draft risk assessments on 5 chemical uses from list of 83

Methylene chloride or dichloromethane (DCM), and n-methylpyrrolidone (NMP) in paint stripper products are among those being studied.

The American Coating Association reports that on Jan. 4, the U.S. Environmental Protection Agency (EPA) released draft risk assessments on five chemical uses from the list of 83 chemical uses up for review under the existing chemicals program.

The ACA says the five chemical uses are: 1) methylene chloride or dichloromethane (DCM), and 2) n-methylpyrrolidone (NMP) in paint stripper products; 3) trichloroethylene (TCE) as a degreaser and a spray-on protective coating; 4) antimony trioxide (ATO) as a synergist in halogenated flame retardants; and 5) 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8,-hexamethylcyclopenta-\[γ]-2-benzopyran (HHCB) as a fragrance ingredient in commercial and consumer products.

ACA is focusing on the review of methylene chloride and n-methylpyrrolidone.  EPA is accepting public comments from peer reviewers until Feb. 8, 2013, and comments on the risk assessments until March 11, 2013.

ACA is searching for possible peer reviewers, and reviewing the risk assessments to draft comments. If you have any comments or suggestions on possible peer reviewers for these five risk assessments, or any of the remaining chemical uses, please contact ACA.
