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), 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 one new equivalent
method for measuring concentrations of sulfur dioxide (SO2)
in ambient air and one new equivalent method for measuring
concentrations of ozone (O3) in ambient air. These
designations are made under the provisions of 40 CFR part 53, as
amended on July 18, 1997 (62 FR 38764).
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 is identified as
follows:
EQSA-0802-149, ``Environnement S.A. Model AF22M UV Fluorescence
Sulfur Dioxide Analyzer,'' operated with a full scale range of 0-500
ppb, at any temperature in the range of 10 [deg]C to 35 [deg]C, with
a 5-micron PTFE sample particulate filter, with a response time
setting of 11 (Automatic response time), with the automatic ``ZERO-
REF'' cycle ON and set for activation every 24 hours, and with or
without either of the following options: Permeation oven, Rack mount
slides.
An application for an equivalent method determination for this
method was received by the EPA on April 30, 2002. The method is
available commercially from the applicant, Environnement S.A., 111,
Boulevard Robespierre, 78304 Poissy, France (http://www.environnement-sa.com).
The new equivalent method for O3 is an automated method
(analyzer) that utilizes a measurement principle based on absorption of
ultraviolet light by ozone at a wavelength of 254 nm. The newly
designated equivalent method is identified as follows:
EQOA-0992-087, ``Teledyne--Advanced Pollution Instrumentation
Model 400E UV Photometric Ozone Analyzer,'' operated on any full
scale range between 0--100 ppb and 0--1000 ppb, with any range mode
(Single, Dual, or Auto Range), at any ambient temperature in the
range of 5 [deg]C to 40 [deg]C, on input power of 115 or 230 Vac
(nominal) and 50-60 Hz, with a PTFE sample particulate filter, with
a sample flow rate of 800 +/-80 cm3/min (sea level), with
the dilution factor set to 1, with Dynamic Zero ON or OFF, with
Dynamic Span OFF, with Temp/Press compensation ON, and with or
without any of the following options: Internal or external sample
pump, Sample/Cal valve option, Internal Zero/Span (IZS), Rack mount
with or without slides, 4-20 mA isolated current loop output.
An application for an equivalent method determination for this
method was received by the EPA on June 4, 2002. The Model 400E is a
modified and updated version of the Advanced Pollution Instrumentation
Model 400/400A, which was previously designated as an equivalent method
(57 FR 44565) and continues to be so designated. The model 400E is
available commercially from the applicant, Teledyne Instruments,
Advanced Pollution Instrumentation Division, 6565 Nancy Ridge Drive,
San Diego, California (http://www.teledyne-api.com).
A test analyzer representative of each of these methods has been
tested by the respective applicant in accordance with the applicable
test procedures specified in 40 CFR part 53 (as amended on July 18,
1997). After reviewing the results of those tests and other information
submitted by the applicants, EPA has determined, in accordance with
part 53, that each of these methods should be designated as an
equivalent method. The information submitted by the applicants 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 a designated reference or equivalent method, each method is
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., measurement range,
operational settings, or temperature range) specified in the applicable
designation 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, Part 1,'' EPA-454/R-98-004. Vendor
modifications of a designated reference or 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 of appendix C to 40
CFR part 58 (Modifications of Methods by Users).
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
[[Page 57813]]
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 these new 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.
Dated: September 4, 2002.
