SUPPLEMENTARY INFORMATION:

The EPA is currently reviewing the NAAQS for PM. Sections 108 and 109 of the CAA require that EPA carry out a periodic review and revision, where appropriate, of the scientific criteria and the NAAQS for “criteria” air pollutants such as PM. Details of EPA's plans for review of the NAAQS for PM were announced in a previous Federal Register notice (62 FR 55201, October 23, 1997). The second external review draft of the Air Quality Criteria for Particulate Matter and the preliminary draft Staff Paper were made available for public review and comment (66 FR 18929, April 12, 2001 and 66 FR 32621, June 15, 2001, respectively).

The draft PM Risk Analysis Methodology document describes EPA's plans and approach for conducting PM health risk analyses for fine particles that will be summarized and discussed Start Printed Page 3898in the next draft of the Staff Paper. The risk analysis will be performed to assist in the preparation of the OAQPS Staff Paper, which is to evaluate the policy implications of the key scientific and technical information contained in the Air Quality Criteria document and identify critical elements that EPA staff believe should be considered in reviewing the NAAQS. The Staff Paper is intended to “bridge the gap” between the scientific review contained in the Air Quality Criteria document and the public health and welfare policy judgments required of the Administrator in reviewing the NAAQS.

The draft PM Risk Analysis Methodology will be reviewed at an upcoming public teleconference of the Clean Air Scientific Advisory Committee (CASAC) of EPA's Science Advisory Board. A future Federal Register notice will inform the public of the date and details of that meeting. Following the CASAC meeting, EPA will revise the draft Risk Analysis Methodology taking into account public and CASAC comments, and proceed with the risk analyses.
