Environmental Protection Agency (EPA).
Notice of public comment period.
The Environmental Protection Agency (EPA) is announcing a public comment period for the draft document titled, “Integrated Science Assessment for Particulate Matter (External Review Draft)” (EPA/600/R-18/179). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development (ORD) as part of the review of the primary (health-based) and secondary (welfare-based) National Ambient Air Quality Standards (NAAQS) for particulate matter. The welfare-based effects evaluated consist of non-ecological effects, specifically visibility impairment, climate effects, and effects on materials. The Integrated Science Assessment (ISA), in conjunction with additional technical and policy assessments, provides the scientific basis for EPA's decisions on the adequacy of the current NAAQS and the appropriateness of possible alternative standards. EPA is currently developing a separate ISA to support the secondary NAAQS review for ecological effects for oxides of nitrogen, oxides of sulfur, and particulate matter.
EPA is releasing this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public. In addition, the date and location of a public meeting for CASAC review of this document will be specified in a separate Federal Register notice. This draft document is not final and it does not represent, and should not be construed to represent, any final Agency policy or views. When revising the document, EPA will consider any public comments submitted during the public comment period specified in this notice.
The public comment period begins on October 23, 2018, and ends December 11, 2018. Comments must be received on or before December 11, 2018.
The “Integrated Science Assessment for Particulate Matter (External Review Draft)” will be available primarily via the internet on EPA's Integrated Science Assessment Particulate Matter page at https://www.epa.gov/isa/integrated-science-assessment-isa-particulate-matter or the public docket at http://www.regulations.gov, Docket ID: EPA-HQ-ORD-2014-0859. A limited number of CD-ROM copies will be available. Contact Ms. Marieka Boyd by phone: 919-541-0031; fax: 919-541-5078; or email: email@example.com to request a CD-ROM, and please provide your name; your mailing address; and the document title, “Integrated Science Assessment for Particulate Matter (External Review Draft)” to facilitate processing of your request.

I. Information About the Document
Section 108(a) of the Clean Air Act directs the Administrator to identify certain pollutants which, among other things, “cause or contribute to air pollution which may reasonably be anticipated to endanger public health or 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 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 or welfare. EPA is also required to review and, if appropriate, revise the NAAQS, based on the revised air quality criteria (for more information on the Start Printed Page 53472NAAQS review process, see https://www.epa.gov/criteria-air-pollutants/process-reviewing-national-ambient-air-quality-standards).
Particulate matter is one of six criteria pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an ISA (formerly called an Air Quality Criteria Document). The ISA, in conjunction with additional technical and policy assessments, provides the scientific basis for EPA's decisions on the adequacy of the current NAAQS and the appropriateness of possible alternative standards. The CASAC, an independent science advisory committee whose review and advisory functions are mandated by Section 109(d)(2) of the Clean Air Act, is charged (among other things) with independent scientific review of the EPA's air quality criteria.
On December 3, 2014 (79 FR 71764), EPA formally initiated its current review of the air quality criteria for the health and welfare effects of particulate matter and the primary (health-based) and secondary (welfare-based) NAAQS, requesting the submission of recent scientific information on specified topics. EPA conducted a workshop from February 9 through 11, 2015 to gather input from invited scientific experts, both internal and external to EPA, as well as from the public, regarding key science and policy issues relevant to the review of the primary and secondary NAAQS (79 FR 71764). These science and policy issues were incorporated into EPA's “Draft Integrated Review Plan for the National Ambient Air Quality Standards for Particulate Matter,” which was available for public comment (81 FR 22977) and discussion by the CASAC via publicly accessible teleconference consultation (81 FR 13362). The “Final Integrated Review Plan for the National Ambient Air Quality Standards for Particulate Matter” was released December 6, 2016 (81 FR 87933).
Subsequent webinar workshops were held on June 9th, 13th, 20th, and 22nd, 2016, to discuss initial draft materials prepared in the development of the particulate matter ISA with invited EPA and external scientific experts (81 FR 29262, May 11, 2016). The input received during these webinar workshops aided in the development of the materials presented in the “Integrated Science Assessment for Particulate Matter (External Review Draft).”
The “Integrated Science Assessment for Particulate Matter (External Review Draft)” will be discussed at a public meeting for review by CASAC. In addition to the public comment period announced in this notice, the public will have an opportunity to address CASAC at this meeting. A separate Federal Register notice will inform the public of the exact date and time of the CASAC meeting and of the procedures for public participation.
