Availability of Meeting Materials: Prior to the meeting, the review documents, agenda and other materials will be available on the CASAC Web page at http://www.epa.gov/casac/. Procedures for Providing Public Input: Public comment for consideration by EPA’s federal advisory committees and panels has a different purpose from public comment provided to EPA program offices. Therefore, the process for submitting comments to a federal advisory committee is different from the process used to submit comments to an EPA program office. Federal advisory committees and panels, including scientific advisory committees, provide independent advice to EPA. Members of the public can submit relevant comments on the topic of this advisory activity, including the charge to the panel and the EPA review documents, and/or the group conducting the activity, for the CASAC to consider as it develops advice for EPA. Input from the public to the CASAC will have the most impact if it provides specific scientific or technical information or analysis for CASAC panels to consider or if it relates to the clarity or accuracy of the technical information. Members of the public wishing to provide comment should follow the instructions below to submit comments. Oral Statements: In general, individuals or groups requesting an oral presentation at a public meeting will be limited to five minutes. Each person making an oral statement should consider providing written comments as well as their oral statement so that the points presented orally can be expanded upon in writing. Interested parties should contact Dr. Thomas Armitage, DFO, in writing (preferably via email) at the contact information noted above by May 17, 2017, to be placed on the list of public speakers. Written Statements: Written statements will be accepted throughout the advisory process; however, for timely consideration by CASAC members, statements should be supplied to the DFO (preferably via email) at the contact information noted above by May 17, 2017. It is the SAB Staff Office general policy to post written comments on the Web page for the advisory meeting or teleconference. Submitters are requested to provide an unsigned version of each document because the SAB Staff Office does not publish documents with signatures on VerDate Sep<11>2014 19:09 Mar 29, 2017 Jkt 241001 its Web sites. Members of the public should be aware that their personal contact information, if included in any written comments, may be posted to the CASAC Web site. Copyrighted material will not be posted without explicit permission of the copyright holder. Accessibility: For information on access or services for individuals with disabilities, please contact Dr. Armitage at (202) 564–2155 or armitage.thomas@ epa.gov. To request accommodation of a disability, please contact Dr. Armitage preferably at least ten days prior to each meeting to give EPA as much time as possible to process your request.

ACTION: Notice of public comment period. AGENCY: Environmental Protection Agency (EPA) is announcing a public comment period for the draft document titled, ‘‘First External Review Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter—Ecological Criteria’’ (EPA/600/R–16/372). 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). In addition, EPA is currently developing separate ISAs to support the primary SUMMARY: PO 00000 Frm 00018 Fmt 4703 Sfmt 4703 NAAQS review for oxides of sulfur and the primary and non-ecological secondary (e.g., visibility, climate, materials damage) NAAQS review 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.

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 E:\FR\FM\30MRN1.SGM 30MRN1 asabaliauskas on DSK3SPTVN1PROD with NOTICES Federal Register / Vol. 82, No. 60 / Thursday, March 30, 2017 / Notices 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 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. 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 VerDate Sep<11>2014 19:09 Mar 29, 2017 Jkt 241001 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, 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 final ‘‘Integrated Review Plan for the Secondary National Ambient Air Quality Standard for Oxides of Nitrogen, Oxides of Sulfur, and Particulate Matter’’ will be announced by a separate Federal Register notice. 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. The ‘‘First 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.

First 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: Environmental Protection Agency (EPA) is announcing a public 
comment period for the draft document titled, ``First External Review 
Draft Integrated Science Assessment for Oxides of Nitrogen, Oxides of 
Sulfur, and Particulate Matter--Ecological Criteria'' (EPA/600/R-16/
372). 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). In addition, 
EPA is currently developing separate ISAs to support the primary NAAQS 
review for oxides of sulfur and the primary and non-ecological 
secondary (e.g., visibility, climate, materials damage) NAAQS review 
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 March 30, 2017, and ends on 
May 24, 2017. Comments must be received on or before May 24, 2017.

ADDRESSES: The ``First External Review Draft Integrated Science 
Assessment for Oxides of Nitrogen, Oxides of Sulfur, and Particulate 
Matter--Ecological Criteria'' will be available primarily via the

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

[[Page 15703]]

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 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. 
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, 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 final ``Integrated Review Plan for the Secondary National 
Ambient Air Quality Standard for Oxides of Nitrogen, Oxides of Sulfur, 
and Particulate Matter'' will be announced by a separate Federal 
Register notice.
    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.
    The ``First 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.

    Instructions: Direct your comments to Docket ID No. EPA-HQ-ORD-
2013-0620 and Docket ID No. EPA-HQ-OAR-2014-0128. Please ensure that 
your comments are submitted within the specified comment period. 
Comments received after the closing date will be marked ``late,'' and 
may only be considered if time permits. It is EPA's policy to include 
all comments it receives in the public docket without change and to 
make the comments available online at www.regulations.gov, including 
any personal information provided, unless a comment includes 
information claimed to be Confidential Business Information (CBI) or 
other information whose disclosure is restricted by statute. Do not 
submit information through www.regulations.gov or email that you 
consider to be CBI or otherwise protected. The www.regulations.gov Web 
site is an ``anonymous access'' system, which means EPA will not know 
your identity or contact information unless you provide it in the body 
of your comment. If you send an email comment directly to EPA without 
going through www.regulations.gov, your email address will be 
automatically captured and included as part of the comment that is 
placed in the public docket and made available on the internet. If you 
submit an electronic comment, EPA recommends that you include your name 
and other contact information in the body of your comment and with any 
disk or CD-ROM you submit. If EPA cannot read your comment due to 
technical difficulties and cannot contact you for clarification, EPA 
may not be able to consider your comment. Electronic files should avoid 
the use of special characters, any form of encryption, and be free of 
any defects or viruses. For additional information about EPA's public 
docket visit the EPA Docket Center homepage at https://www.epa.gov/dockets.
