Abstract
EPA then made a Second External Review Draft of the Air Quality Criteria for Particulate Matter available for CASAC and public review in April 2001 (66 FR 18929, April 12, 2001). Following that public review period and a second CASAC meeting in July 2001 (66 FR 34924, July 2, 2001), EPA again revised the document as appropriate to incorporate changes in response to CASAC and public comments and also made further revisions reflecting new studies on effects of particulate matter that had become available between issuance of the First and Second External Review Drafts.
EPA then made a Third External Review Draft of the Air Quality Criteria for Particulate Matter available for CASAC and public review in May 2002 (67 FR 31303, May 9, 2002). Following that public review period and a third CASAC meeting in July 2002 (67 FR 41723, June 19, 2002), EPA again revised the document as appropriate to incorporate revisions in response to CASAC and public comments and also made further revisions reflecting new studies on effects of particulate matter that had become available between issuance of the Second and Third External Review Drafts, as well as reanalyses of certain existing studies occasioned after discovery of problems with applications of statistical software.
EPA made a Fourth External Review Draft available for CASAC and public review in June 2003 (68 FR 36985). A public meeting with CASAC was held August 25-26, 2003, during which CASAC reached closure on Chapters 1,2,3,4,5, and 6, with only relatively minor final revisions to be made. No further public review is requested on these chapters. However, CASAC did not reach closure on Chapters 7 (toxicology), 8 (human health), and 9 (integrative synthesis), each of which are to be more extensively revised or, in the case of chapter 9, to be significantly restructured. Since then CASAC has provided additional review comments on revised drafts of Chapters 7 and 8 (dated December 2003).
EPA is now making further revised drafts of Chapters 7, 8, and 9 available for CASAC and public review. These revised draft chapters will be reviewed by CASAC at a public meeting to be held July 20-21, 2004 in the RTP, NC area. (For information on the CASAC meeting see 69 FR 32344, June 9, 2004.)
