Advocacy Urges EPA to Wait for Best Available Science Before Completing Final Toxicological Review of Hexavalent Chromium

 Advocacy Urges EPA to Wait for Best Available Science Before Completing Final Toxicological Review of Hexavalent Chromium  

On October 4, 2011, the Office of Advocacy (Advocacy) submitted a comment letter to the U.S. Environmental Protection Agency (EPA) discussing Advocacy’s views on EPA’s Draft Toxicological Review of Hexavalent Chromium (Cr(VI)) and the Integrated Risk Information System (IRIS) program in general. Advocacy’s comment letter includes the following points: 
 

  • Advocacy recommends EPA postpone its final toxicological review of Cr(VI) until the industry studies, currently in progress, are completed. Data gaps in the existing scientific data do not provide EPA with sufficiently accurate scientific data and are not the best available science on which to base the toxicological review. These studies are set to be completed by the end of 2011. 
     
  • Advocacy supports EPA’s efforts to improve the IRIS program. Advocacy believes that the Cr(VI) toxicological review presents EPA with a good opportunity to continue to fulfill its pledge to improve the program which EPA can do by basing its evaluation on the best available science and by rewriting the Draft Toxicological Review.
