The purpose of the Staff Paper is to evaluate the policy implications of the key scientific and technical information contained in a related EPA document, Air Quality Criteria for Particulate Matter, required under sections 108 and 109 of the Clean Air Act (CAA) for use in the periodic review of the national ambient air quality standards (NAAQS) for particulate matter (PM). The OAQPS also will make available for public review and comment a draft EPA document entitled, Particulate Matter NAAQS Risk Analysis Scoping Plan.

DATES:

Comments on the preliminary draft Staff Paper and draft Risk Analysis Scoping Plan should be submitted on or before July 12, 2001.

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 was recently made available for public review and comment (66 FR 18929, April 12, 2001).

The purpose of the Staff Paper 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 (Natural Resources Defense Council v. Administrator, 902 F.2d 962, 967 (D.C. Cir. 1990).

This preliminary draft Staff Paper includes preliminary assessments of the scientific and technical information contained in the draft Air Quality Criteria document and discusses proposed analyses to be conducted for inclusion in a subsequent draft Staff Paper. Staff conclusions and recommendations on the PM NAAQS are not included in this preliminary draft but will be included in a subsequent draft to be made available for further review and comment as indicated below.

The draft Risk Analysis Scoping Plan describes EPA's plans and approach for conducting PM health risk analyses that will be summarized and discussed in the next draft of the Staff Paper.

The preliminary draft Staff Paper and draft Risk Analysis Scoping Plan, along with the second external review draft of the Air Quality Criteria for PM, will be reviewed at an upcoming public meeting 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 location of that meeting. Following the CASAC meeting, EPA will prepare a revised draft Staff Paper, taking into account public and CASAC comments, and will make the revised draft available for further review and comment by CASAC and the public.
