Notice of a draft for public review and comment.
On or about January 31, 2005, the Office of Air Quality Planning and Standards (OAQPS) of EPA will make available for public review and comment a draft document, Review of the National Ambient Air Quality Standards for Particulate Matter: Policy Assessment of Scientific and Technical Information (Second Draft Staff Paper). 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 related draft technical support document, Particulate Matter Health Risk Assessment for Selected Urban Areas (Second Draft Risk Assessment).
Comments on the second draft Staff Paper and second draft Risk Assessment should be submitted on or before March 31, 2005.

Section 108(a) of the Clean Air Act directs the Administrator to identify certain pollutants which “may reasonably be anticipated to endanger public health and welfare” and to issue air quality criteria for them. These air quality criteria are to “accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of [a] pollutant in the ambient air. * * *” Under section 109 of the Act, EPA is then to establish National Ambient Air Quality Standards (NAAQS) for each pollutant for which EPA has issued criteria. Section 109(d) of the Act subsequently requires periodic review and, if appropriate, revision of existing air quality criteria to reflect advances in scientific knowledge on the effects of the pollutant on public health and welfare. EPA is also to revise the NAAQS, if appropriate, based on the revised criteria.
Particulate matter is one of six “criteria” pollutants for which EPA has established air quality criteria and NAAQS. EPA is presently reviewing the criteria and NAAQS for PM. This review includes preparation of two key documents, the Air Quality Criteria for particulate matter (“Criteria Document”) and a related “Staff Paper”. EPA completed its Criteria Document for PM in October 2004 (69 FR 63111, October 29, 2004).
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.
In August 2003, a first draft of this Staff Paper was released by EPA for public review and comment and for review by the Clean Air Scientific Advisory Committee (CASAC) of EPA's Science Advisory Board (68 FR 51774, August 28, 2003) at a public meeting held in November 2003. Comments received from review of the first draft document have been considered in preparing this second draft Staff Paper.
Based on the information contained in the Air Quality Criteria document, this second draft Staff Paper includes assessments and analyses related to: (1) Air quality characterization; (2) integration and evaluation of health information; (3) health risk assessment; and (4) evaluation of information on visibility impairment and other welfare effects. The second draft Staff Paper also includes staff conclusions and recommendations on potential revision or retention of the 1997 PM NAAQS. Staff recommendations include consideration of revising both the primary (health-based) and secondary (welfare-based) PM NAAQS.
The second draft Risk Assessment technical support document describes and presents the results from an updated PM health risk assessment. A scoping plan, methodology documents, and the first draft Risk Assessment technical support document were previously reviewed by CASAC and the public. Comments received have been considered in developing the second draft Risk Assessment technical support document being released at this time. The risk assessment methodology and results are also discussed in the second draft Staff Paper.
The second draft Staff Paper and second draft Risk Assessment technical support document will be reviewed at an upcoming public meeting of the CASAC. A future Federal Register notice will inform the public of the date and location of that meeting. Following the CASAC meeting, EPA will consider comments received from CASAC and the public in completing the Staff Paper and Risk Assessment technical support document.Start Signature
