ENVIRONMENTAL PROTECTION AGENCY
[FRL-8494-1]
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods: Designation of Two New Equivalent
Methods
AGENCY: Environmental Protection Agency.
ACTION: Notice of the designation of two new equivalent methods for
monitoring ambient air quality.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with 40 CFR part 53, two new
equivalent methods: One for measuring concentrations of ozone
(O3) in the ambient air and one for measuring concentrations
of sulfur dioxide (SO2) in the ambient air.
FOR FURTHER INFORMATION CONTACT: Elizabeth Hunike, Human Exposure and
Atmospheric Sciences Division (MD-D205-03), National Exposure Research
Laboratory, U.S. EPA, Research Triangle Park, North Carolina 27711.
Phone: (919) 541-3737, e-mail: [email protected].
SUPPLEMENTARY INFORMATION: In accordance with regulations at 40 CFR
part 53, the EPA evaluates various methods for monitoring the
concentrations of those ambient air pollutants for which EPA has
established National Ambient Air Quality Standards (NAAQSs) as set
forth in 40 CFR part 50. Monitoring methods that are determined to meet
specific requirements for adequacy are designated by the EPA as either
reference methods or equivalent methods (as applicable), thereby
permitting their use under 40 CFR part 58 by States and other agencies
for determining attainment of the NAAQSs.
The EPA hereby announces the designation of two new equivalent
methods for measuring concentrations of O3 and
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 equivalent method for O3 is an automated method
that utilizes a measurement principle based on non-dispersive
ultraviolet absorption photometry. The newly designated equivalent
method for O3 is identified as follows:
EQOA-1107-169, ``DKK-TOA Corporation Model GUX-313 E Ambient
O3 Analyzer,'' operated at any environmental temperature
in the range of 20 [deg]C to 30 [deg]C on any of the following
measurement ranges: 0-0.1 ppm, 0-0.2 ppm and 0-0.5 ppm.
An application for an equivalent method determination for the
candidate method was received by the EPA on July 12, 2007. The sampler
is commercially available from the applicant, DKK-TOA Corporation, 29-
10, 1-Chome, Takadanobaba, Shinjuku-ku, Tokyo 169-8648, Japan (http://www.toadkk.co.jp).
The new equivalent method 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:
EQSA-1107-168, ``DKK-TOA Corporation Model GFS-312 E Ambient
SO2 Analyzer,'' operated at any environmental temperature
in the range of 20 [deg]C to 30 [deg]C on any of the following
measurement ranges: 0-0.1 ppm, 0-0.2 ppm and 0-0.5 ppm.
An application for an equivalent method determination for the
candidate method was received by the EPA on September 18, 2007. The
sampler is commercially available from the applicant, DKK-TOA
Corporation, 29-10, 1-Chome, Takadanobaba, Shinjuku-ku, Tokyo 169-8648,
Japan (http://www.toadkk.co.jp).
Test analyzers representative of each 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
[[Page 63177]]
and other information submitted by the applicant in the application,
EPA has determined, in accordance with part 53, that these methods
should be designated as equivalent methods. The information submitted
by the applicant in the application 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 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,
the 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 designation method description
(see the identifications of the method 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, Part 1,'' EPA-454/R-98-004 (available
at http://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 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 and are summarized below:
(a) A copy of the approved operation or instruction manual must
accompany the sampler or analyzer when it is delivered to the ultimate
purchaser.
(b) The sampler or analyzer must not generate any unreasonable
hazard to operators or to the environment.
(c) The sampler or analyzer must function within the limits of the
applicable performance specifications given in 40 CFR parts 50 and 53
for at least one year after delivery when maintained and operated in
accordance with the operation or instruction manual.
(d) Any sampler or analyzer offered for sale as part of a reference
or equivalent method must bear a label or sticker indicating that it
has been designated as part of a reference or equivalent method in
accordance with Part 53 and showing its designated method
identification number.
(e) If such an analyzer has two or more selectable ranges, the
label or sticker must be placed in close proximity to the range
selector and indicate which range or ranges have been included in the
reference or equivalent method designation.
(f) An applicant who offers samplers or analyzers for sale as part
of a reference or equivalent method is required to maintain a list of
ultimate purchasers of such samplers or analyzers and to notify them
within 30 days if a reference or equivalent method designation
applicable to the method has been canceled or if adjustment of the
sampler or analyzer is necessary under 40 CFR 53.11(b) to avoid a
cancellation.
(g) An applicant who modifies a sampler or analyzer previously
designated as part of a reference or equivalent method is not permitted
to sell the sampler or analyzer (as modified) as part of a reference or
equivalent method (although it may be sold without such
representation), nor to attach a designation label or sticker to the
sampler or analyzer (as modified) under the provisions described above,
until the applicant has received notice under 40 CFR 53.14(c) that the
original designation or a new designation applies to the method as
modified, or until the applicant has applied for and received notice
under 40 CFR 53.8(b) of a new reference or equivalent method
determination for the sampler or analyzer as modified.
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 this new equivalent method 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.

Acting Director, National Exposure Research Laboratory.
