EPA Issues Revised PM Epidemiology and Toxicology Chapters, 12/30/03
EPA has issued the fifth revised drafts of the Toxicology and Epidemiology chapters of the Criteria Document on particulate matter for public review.
At a public meeting of the Clean Air Science Advisory Committee (CASAC) on August 25-26, 2003, CASAC reached closure on Chapters 1,2,3,4,5, and 6, with only relatively minor final revisions to be made.
However, CASAC did not reach closure on Chapters 7 (toxicology), 8 (epidemiology), and 9 (integrative synthesis), each of which are to be more extensively revised or, in the case of chapter 9, to be significantly restructured.
EPA is now making revised drafts of Chapters 7 and 8 available for CASAC and public review.
These two revised draft chapters will be reviewed by CASAC via a publically accessible teleconference call in late January, 2004.
Following that CASAC teleconference, Chapter 9, the integrative synthesis, will be released for CASAC and public review at a public meeting in early March.
Written comments on the Toxicology and Epidemiology chapters must be submitted by January 31, 2004 to:
Project Manager for Particulate Matter
National Center for Environmental Assessment–RTP (B243-01)
U.S. Environmental Protection Agency
Research Triangle Park, NC 27711
EPA has published the chapters online.
