[Federal Register Volume 83, Number 123 (Tuesday, June 26, 2018)] [Notices] [Pages 29786-29788] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-13713] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY [Docket ID No. EPA-HQ-ORD-2013-0620 and Docket ID No. EPA-HQ-OAR-2014- 0128; FRL-9979-52-ORD] Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter-- Ecological Criteria AGENCY: Environmental Protection Agency (EPA). ACTION: Notice of public comment period. ----------------------------------------------------------------------- SUMMARY: The Environmental Protection Agency (EPA) is announcing a public comment period for the draft document titled, ``Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter--Ecological Criteria'' (EPA/ 600/R-18/097). 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 secondary (welfare- based) National Ambient Air Quality Standards (NAAQS) for oxides of nitrogen, oxides of sulfur, and particulate matter. 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. On January 28, 2016, EPA released a separate ISA as part of an independent review for the primary (health- based) NAAQS for oxides of nitrogen (EPA/600/R-15/068). [[Page 29787]] In addition, EPA also released a separate ISA to support the primary NAAQS review for oxides of sulfur (EPA/600/R-17/451, December 13, 2017), and is currently reviewing the primary and non-ecological secondary (e.g., visibility, climate, materials damage) NAAQS for particulate matter. EPA is releasing this draft document to seek review by the Clean Air Scientific Advisory Committee (CASAC) and the public (meeting date and location to be specified in a separate Federal Register notice). This draft document is not final, as described in EPA's information quality guidelines, and it does not represent, and should not be construed to represent, Agency policy or views. When revising the document, EPA will consider any public comments submitted during the public comment period specified in this notice. DATES: The public comment period begins on June 26, 2018 and ends on September 4, 2018. Comments must be received on or before September 4, 2018. ADDRESSES: The ``Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter--Ecological Criteria'' will be available primarily via the internet on EPA's Integrated Science Assessment home page at https://www.epa.gov/isa/integrated-science-assessment-isa-oxides-nitrogen-and-sulfur-ecological or the public docket at http://www.regulations.gov, Docket ID No. EPA-HQ-ORD-2013-0620 and Docket ID No. EPA-HQ-OAR-2014- 0128. 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 protected] to request a CD-ROM, and please provide your name, your mailing address, and the document title, ``Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter--Ecological Criteria'' to facilitate processing of your request. FOR FURTHER INFORMATION CONTACT: For information on the public comment period, contact the ORD Docket at the EPA Headquarters Docket Center; phone: 202-566-1752; fax: 202-566-9744; or email: [email protected]. For technical information, contact Dr. Tara Greaver, NCEA; phone: 919-541-2435; fax: 919-541-1818; or email: [email protected]. SUPPLEMENTARY INFORMATION: 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 (for more information on the NAAQS review process, see https://www.epa.gov/naaqs). Oxides of nitrogen, oxides of sulfur, and particulate matter are three 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 Clean Air Scientific Advisory Committee (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 August 21, 2013 (78 FR 53452), EPA formally initiated its current review of the air quality criteria for the ecological effects of oxides of nitrogen and oxides of sulfur, and the associated secondary (welfare-based) NAAQS, requesting the submission of recent scientific information on specified topics. Similarly, on December 3, 2014 (79 FR 71764), EPA formally initiated its current review of the air quality criteria for the particulate matter NAAQS. EPA conducted two workshops--the first on March 4 to 6, 2014 for oxides of nitrogen and oxides of sulfur (79 FR 8644, February 13, 2014), and the second on February 11, 2015 (79 FR 71764, December 3, 2014) for particulate matter--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 these secondary NAAQS. Teleconference workshops with invited scientific experts, both internal and external to EPA, were held on August 25, 26, and 27, 2015 (80 FR 48316, August 12, 2015) and June 13, 2016 (81 FR 89262, May 11, 2016), to discuss initial draft materials prepared in the development of the draft ISA. These science and policy issues were incorporated into EPA's ``Draft Integrated Review Plan for the Secondary National Ambient Air Quality Standard for Oxides of Nitrogen and Oxides of Sulfur'' as well as the ``Integrated Review Plan for the National Ambient Air Quality Standards for Particulate Matter.'' The Draft Integrated Review Plan (IRP) for oxides of nitrogen and oxides of sulfur was available for public comment (80 FR 69220, Monday, November 9, 2015) and discussion by the CASAC via publicly accessible teleconference consultation (80 FR 65223, February 10, 2016). The Draft IRP for particulate matter was available for public comment (81 FR 2297, April 19, 2016) and discussion by the CASAC via publicly accessible teleconference consultation (81 FR 13362, March 14, 2016) prior to release of the final document (81 FR 87933, December 6, 2016). The ``First External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter--Ecological Criteria'' was available for public comment (82 FR 15703, March 30, 2017) and discussed by CASAC and the public (82 FR 15701, March 30, 2017). The ``Second External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter-- Ecological Criteria'' will be discussed at a public meeting for review by CASAC and the public. In addition to the public comment period announced in this notice, the public will have an opportunity to address the CASAC. 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. II.
