Download as PDF Federal Register / Vol. 74, No. 146 / Friday, July 31, 2009 / Notices concentrations of O3 in the ambient air and one for measuring SO2 in the ambient air. These designations are made under the provisions of 40 CFR Part 53, as amended on December 18, 2006 (71 FR 61271). The new reference method for NOX is an automated method (analyzer) utilizing the measurement principle based on gas phase chemiluminescence and the calibration procedure specified in Appendix F of 40 CFR part 50. This newly designated reference method is identified as follows: RFNA–0809–186, ‘‘Ecotech Serinus 40 Oxides of Nitrogen Analyzer’’, operated in the range of 0–0.5 ppm, with a five-micron Teflon® filter element installed, and with the following selected: Control Loop-Enabled, Diagnostic Mode-Operate, Pres/Temp/Flow Compensation-Enabled, Span CompensationDisabled, with concentration automatically corrected for temperature and pressure changes, and operated according to the Serinus 40 Oxides of Nitrogen Analyzer User Manual. The new equivalent method for O3 is an automated method that utilizes a measurement principle based on nondispersive ultraviolet absorption photometry. The newly designated equivalent method for O3 is identified as follows: EQOA–0809–187, ‘‘Ecotech Serinus 10 Ozone Analyzer’’, operated in the range of 0– 0.5 ppm, with a five-micron Teflon® filter element installed, and with the following selected: Control Loop-Enabled, Diagnostic Mode-Operate, Pres/Temp/Flow Compensation-Enabled, Span CompensationDisabled, with concentration automatically corrected for temperature and pressure changes, and operated according to the Serinus 10 Ozone Analyzer User Manual. The new equivalent method for SO2 is an automated method (analyzer) that utilizes a measurement principle based on ultraviolet fluorescence. The newly designated equivalent method for SO2 is identified as follows: PWALKER on DSK8KYBLC1PROD with NOTICES EQSA–0809–188, ‘‘Ecotech Serinus 50 Sulfur Dioxide Analyzer’’, operated in the range of 0–0.5 ppm, with a five-micron Teflon® filter element installed, and with the following selected: Background-Enabled, Control Loop-Enabled, Diagnostic ModeOperate, Pres/Temp/Flow CompensationEnabled, Span Compensation-Disabled, with concentration automatically corrected for temperature and pressure changes, and operated according to the Serinus 50 Sulfur Dioxide Analyzer User Manual. Applications for the reference method and equivalent method determinations for these candidate methods were received by the EPA on March 19, 2008, April 22, 2009 and June 22, 2009, respectively. The monitors are commercially available from the applicant, Ecotech Pty. Ltd., 1492 VerDate Nov<24>2008 16:38 Jul 30, 2009 Jkt 217001 Ferntree Gully Road, Knoxfield, Victoria, 3180, Australia. Test analyzers representative of these methods have been tested in accordance with the applicable test procedures specified in 40 CFR Part 53 (as amended on December 18, 2006). After reviewing the results of those tests and other information submitted by the applicant in the respective applications, EPA has determined, in accordance with Part 53, that these methods should be designated as a reference or equivalent method, as appropriate. The information submitted by the applicant in the respective applications will be kept on file, either at EPA’s National Exposure Research Laboratory, Research Triangle Park, North Carolina 27711 or in an approved archive storage facility, and will be available for inspection (with advance notice) to the extent consistent with 40 CFR Part 2 (EPA’s regulations implementing the Freedom of Information Act). As designated reference or equivalent methods, these methods are acceptable for use by states and other air monitoring agencies under the requirements of 40 CFR Part 58, Ambient Air Quality Surveillance. For such purposes, each method must be used in strict accordance with the operation or instruction manual associated with the method and subject to any specifications and limitations (e.g., configuration or operational settings) specified in the applicable designated method description (see the identifications of the methods above). Use of the method should also be in general accordance with the guidance and recommendations of applicable sections of the ‘‘Quality Assurance Handbook for Air Pollution Measurement Systems, Volume I,’’ EPA/ 600/R–94/038a and ‘‘Quality Assurance Handbook for Air Pollution Measurement Systems, Volume II, Ambient Air Quality Monitoring Program’’ EPA–454/B–08–003, December, 2008 (available at https:// www.epa.gov/ttn/amtic/qabook.html). Vendor modifications of a designated equivalent method used for purposes of Part 58 are permitted only with prior approval of the EPA, as provided in Part 53. Provisions concerning modification of such methods by users are specified under Section 2.8 (Modifications of Methods by Users) of Appendix C to 40 CFR Part 58. In general, a method designation applies to any sampler or analyzer which is identical to the sampler or analyzer described in the application for designation. In some cases, similar samplers or analyzers manufactured prior to the designation may be PO 00000 Frm 00021 Fmt 4703 Sfmt 4703 38185 upgraded or converted (e.g., by minor modification or by substitution of the approved operation or instruction manual) so as to be identical to the designated method and thus achieve designated status. The manufacturer should be consulted to determine the feasibility of such upgrading or conversion. Part 53 requires that sellers of designated reference or equivalent method analyzers or samplers comply with certain conditions. These conditions are specified in 40 CFR 53.9. Aside from occasional breakdowns or malfunctions, consistent or repeated noncompliance with any of these conditions should be reported to: Director, Human Exposure and Atmospheric Sciences Division (MD– E205–01), National Exposure Research Laboratory, U.S. Environmental Protection Agency, Research Triangle Park, North Carolina 27711. Designation of these new reference and equivalent methods is intended to assist the States in establishing and operating their air quality surveillance systems under 40 CFR Part 58. Questions concerning the commercial availability or technical aspects of the method should be directed to the applicant. Jewel F. Morris, Acting Director, National Exposure Research Laboratory.

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 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 or welfare. EPA is also to revise the 
NAAQS, if appropriate, based on the revised air quality criteria.
    Particulate matter (PM) is one of six principal (or ``criteria'') 
pollutants for which EPA has established NAAQS. Periodically, EPA 
reviews the scientific basis for these standards by preparing an 
Integrated Science Assessment (ISA) (formerly called an Air Quality 
Criteria Document). The ISA and supplementary annexes, in conjunction 
with additional technical and policy assessments, provide the 
scientific basis for EPA 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 existence and whose review and advisory 
functions are mandated by Section 109(d)(2) of the Act, is charged 
(among other things) with independent scientific review of EPA's air 
quality criteria.
    On June 28, 2007 (72 FR 35462), EPA formally initiated its current 
review of the air quality criteria for PM, requesting the submission of 
recent scientific information on specified topics. A draft of EPA's 
``Integrated Review Plan for the National Ambient Air Quality Standard 
for Particulate Matter'' (EPA/452/P-08-006) was made available in 
October 2007 for public comment and was discussed by the CASAC PM 
Review Panel via a publicly accessible teleconference consultation on 
November 30, 2007 (72 FR 63177). EPA finalized the plan and made it 
available in March 2008 (EPA/452/R-08-004; https://www.epa.gov/ttn/naaqs/standards/pm/s_pm_2007_pd.html). In June 2008 (73 FR 30391), 
EPA held a workshop to discuss, with invited scientific experts, 
initial draft materials prepared in the development of the PM ISA and 
its supplementary annexes.
    The First External Review Draft ISA for PM (EPA/600/R-08/139 and 
EPA/600/R-08/139A; https://cfpub.epa.gov/ncea/cfm/recordisplay.cfm?deid=201805) was released on December 22, 2008 (73 FR 
77686). This document was reviewed by the CASAC and discussed at a 
public meeting on April 1 and 2, 2009 (74 FR 7688). The CASAC held a 
follow-up public teleconference on May 7, 2009 (74 FR 18230) to review 
and approve the CASAC PM Review Panel's draft letter providing comments 
to the Agency on the First External Review Draft ISA for PM (https://
yosemite.epa.gov/sab/sabproduct.nsf/73ACCA834AB44A10852575BD0064346B/
$File/EPA-CASAC-09-008-unsigned.pdf).
    The second external review draft ISA for PM will be reviewed and 
discussed by CASAC at a public meeting. Public comments received will 
be provided to the CASAC PM Review Panel. A future Federal Register 
notice will inform the public of the exact date and time of that CASAC 
meeting.

2007-0517. 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 https://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 https://www.regulations.gov or e-mail

that you consider to be CBI or otherwise protected. The https://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 e-mail comment 
directly to EPA without going through https://www.regulations.gov, your 
e-mail 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/epahome/dockets.htm.
    Docket: Documents in the docket are listed in the https://www.regulations.gov index. Although listed in the index, some 
information is not publicly available, e.g., CBI or other information 
whose disclosure is restricted by statute. Certain other materials, 
such as copyrighted material, are publicly available only in hard copy. 
Publicly available docket materials are available either electronically 
in https://www.regulations.gov or in hard copy at the OEI Docket in the 
EPA Headquarters Docket Center.
