Ambient Air Monitoring Reference and Equivalent Methods:
Designation of a New Reference Method for CO and a New Equivalent
Method for O3
AGENCY: Environmental Protection Agency.
ACTION: Notice of designation of new reference and equivalent methods
for ambient air monitoring.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with 40 CFR part 53, a new
reference method for measuring concentrations of CO in ambient air and
a new equivalent method for measuring concentrations of O3
in 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), 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 reference
method for measuring concentrations of carbon monoxide (CO) 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 reference method for CO is an automated method that
utilizes the measurement principle based on non-dispersive infra-red
absorption photometry (combined with gas filter correlation) and the
calibration procedure specified in appendix C of 40 CFR part 50. The
newly designated reference method is identified as follows: RFCA-0206-
147, ``Environnement S.A Model CO12M Gas Filter Correlation Carbon
Monoxide Analyzer,'' operated with a full scale range of 0-50 ppm, at
any temperature in the range of 10 deg.C to 35 deg.C, on a nominal
power line voltage of 115 Vac (50 or 60 Hz) or 230 Vac (50 Hz), with a
5-micron PTFE sample particulate filter, with response time ON, and
with the automatic ``ZERO-REF'' cycle either ON or OFF.
An application for a reference method determination for this method
was received by the EPA on February 8, 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
that utilizes a measurement principle based on non-dispersive
ultraviolet absorption photometry. The newly designated reference
method is identified as follows:
EQOA-0206-148, ``Environnement S.A Model O342M UV
Photometric Ozone 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, on a
nominal power line voltage of 115 Vac (50 or 60 Hz) or 230 Vac (50 Hz),
with a 5-micron PTFE sample particulate filter, with response time
setting of 11 (Automatic response time), and with or without any of the
following options:
(a) Internal ozone generator,
(b) Span external control (zero/span solenoid valve).
An application for an equivalent method determination for this
method was received by the EPA on November 13, 2001. The method is
available commercially from the applicant, Environnement S. A., 111,
Boulevard Robespierre, 78304 Poissy, France (http://www.environnement-sa.com).
Test analyzers representative of each of these methods have been
tested by the 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 applicant, EPA has determined, in accordance with part
53, that these methods should be designated as a reference method and
an equivalent method, respectively. The information submitted by the
applicant 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 of these
methods 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.,
configuration, sample period, or temperature range) specified in the
applicable designation method description (see the identification of
the methods above). Use of the method should also be in general
accordance with the guidance and recommendations of applicable sections
[[Page 42558]]
of the ``Quality Assurance Handbook for Air Pollution Measurement
Systems, Volume II, EPA/600/R-94/0386.'' 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 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.
(h) An applicant who offers PM2.5 samplers for sale as
part of a reference or equivalent method is required to maintain the
manufacturing facility in which the sampler is manufactured as an ISO
9001-certified facility.
(i) An applicant who offers PM2.5 samplers for sale as
part of a reference or equivalent method is required to submit annually
a properly completed Product Manufacturing Checklist, as specified in
part 53.
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 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 either of the methods
should be directed to the applicant.
Dated: June 12, 2002.
