ENVIRONMENTAL PROTECTION AGENCY
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods; Reference and Equivalent Method
Designations
Notice is hereby given that EPA, in accordance with 40 CFR part 53,
has designated two additional equivalent methods and one additional
reference method for ambient air monitoring. One of the equivalent
methods is for the measurement of ambient concentrations of ozone and
the other is for the measurement of ambient concentrations of lead. The
reference method is for the measurement of ambient concentrations of
carbon monoxide.
The new equivalent method for ozone is an automated method
(analyzer) which utilizes the measurement principle based on absorption
of ultraviolet radiation by ozone at a wavelength of 254 nm. This new
designated method is identified as follows:
EQOA-0895-105, ``Environment S.A. Model Q341M UV Photometric Ozone
Analyzer,'' operated on a full scale range of 0-500 ppb, at any
temperature in the range of 15 deg. C to 35 deg. C, with the response
time set to 50 seconds, and with or without any of the following
options:
(1) Internal Ozone Generator
(2) Span External Control
(3) RS232-422 Serial Interface
(4) Internal Printer
Note: In addition to the standard U.S. electrical power voltage
and frequency (115 Vac, 60 Hz), this analyzer is approved for use,
with proper factory configuration, on 50 Hertz line frequency at any
of the following voltage ranges: 105-125 Vac (115 V nominal) or 210-
250 Vac (230 V nominal).
This method is available from Environmental S.A., 111, bd
Robespierre, 78300 Poissy, France or from Environment U.S.A., 570
Higuera Street, Suite 25, San Luis Obispo, CA 93401. A notice of
receipt of application for this method appeared in the Federal
Register, Volume 60, Number 111, June 9, 1995, page 30535.
The new reference method for carbon monoxide is an automated method
(analyzer) which utilizes a cross flow modulated version of the
measurement principle (non-dispersive infrared (NDIR) photometry) and
the calibration procedure specified in appendix C of 40 CFR part 50.
The new designated method is identified as follows:
RFCA-0895-106, ``Horiba Instruments Incorporated, Model APMA-360
Ambient Carbon Monoxide Monitor,'' operated on the 0-50 ppm range, with
the Line Setting set to ``MEASURE'', with the Analog Output set to
``MOMENTARY VALUE'', and with or without the optional Rack Mounting
Plate and Side Rails.
Note: In addition to the standard U.S. electrical power voltage
and frequency (115 Vac, 60 Hz), this analyzer is approved for use,
with proper factory configuration, on 50 Hertz line frequency at any
of the following voltage ranges: 100-115 Vac and 220-240 Vac.
This method is available from Horiba Instruments Incorporated,
17671 Armstrong Avenue, Irvine, CA 92714. A notice of receipt of
application for this method appeared in the Federal Register, Volume
60, Number 111, June 9, 1995, page 30535.
A test analyzer representative of each of these methods has been
tested by the respective applicant, in accordance with the test
procedures specified in 40 CFR part 53. After reviewing the results of
these tests and other information submitted by the applicants, EPA has
determined, in accordance with part 53, that these methods should be
designated, respectively, as an
[[Page 39383]]
equivalent method and a reference method.
The new equivalent method for the determination of lead in
suspended particulate matter collected from ambient air uses a graphite
furnace atomic absorption method and is identified as follows:
EQL-0895-107, ``Determination of Lead Concentration in Ambient
Particulate Matter by Flameless (Graphite Furnace) Atomic Absorption
(City of Houston, Texas).''
The applicant's request for an equivalent method determination for
the above method was received on May 23, 1995. This method has been
tested by the applicant, the Health and Human Services Department of
Houston, Texas, in accordance with the test procedures prescribed in 40
CFR part 53. After reviewing the results of these tests and other
information submitted by the applicant, EPA has determined, in
accordance with part 53, that this method should be designated as an
equivalent method.
This method uses the sampling procedure specified in the reference
method for the determination of lead in suspended particulate matter
collected from ambient air (43 FR 46258). Lead in the particulate
matter is solubilized by extraction with nitric acid facilitated by
heat. The lead content of the sample is analyzed by a Perkin Elmer HGA
graphite furnace with Zeeman background correction and AS-40
Autosampler. Technical questions concerning the method should be
directed to the City of Houston, Health and Human Services Department,
Environmental Chemistry Service, 1115 S. Braeswood, Houston, Texas
77030.
The information submitted by the three applicants will be kept on
file at EPA's National Exposure Research Laboratory, Research Triangle
Park, North Carolina 27711 and will be available for inspection 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, each method must be used in strict
accordance with the operation or instruction manual associated with the
method or the procedures and specifications provided in the method
description and subject to any limitations (e.g., operating temperature
range) specified in the applicable designation (see description of the
methods above). Vendor modifications of a designated method used for
purposes of part 58 are permitted only with prior approval of 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 designation applies to any analyzer which is
identical to the analyzer described in the designation. In some cases,
similar analyzers manufactured prior to the designation may be upgraded
(e.g., by minor modification or by substitution of a new operation or
instruction manual) so as to be identical to the designated method and
thus achieve designated status at a modest cost. The manufacturer
should be consulted to determine the feasibility of such upgrading.
States or other agencies using a graphite furnace atomic absorption
method that employs procedures and specifications significantly
different from those in method EQL-0895-107 must seek approval for
their particular method under the provisions of Section 2.8 of Appendix
C to 40 CFR part 58 (Modification of Methods by Users) or may seek
designation of such a method as an equivalent method under the
provisions of 40 CFR part 53.
Part 53 requires that sellers of designated method analyzers comply
with certain conditions. These conditions are given in 40 CFR 53.9 and
are summarized below:
(1) A copy of the approved operation or instruction manual must
accompany the analyzer when it is delivered to the ultimate purchaser.
(2) The analyzer must not generate any unreasonable hazard to
operators or to the environment.
(3) The analyzer must function within the limits of the performance
specifications given in Table B-1 of part 53 for at least one year
after delivery when maintained and operated in accordance with the
operation manual.
(4) Any analyzer offered for sale as a reference or equivalent
method must bear a label or sticker indicating that it has been
designated as a reference or equivalent method in accordance with part
53.
(5) 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.
(6) An applicant who offers analyzers for sale as reference or
equivalent methods is required to maintain a list of ultimate
purchasers of such analyzers and to notify them within 30 days if a
reference or equivalent method designation applicable to the analyzer
has been canceled or if adjustment of the analyzer is necessary under
40 CFR 53.11(b) to avoid a cancellation.
(7) An applicant who modifies an analyzer previously designated as
a reference or equivalent method is not permitted to sell the analyzer
(as modified) as a reference or equivalent method (although he may
choose to sell it without such representation), nor to attach a label
or sticker to the 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 analyzer as modified.
Aside from occasional breakdowns or malfunctions, consistent or
repeated noncompliance with any of these conditions should be reported
to: Director, National Exposure Research Laboratory, Air Measurements
Research Division (MD-78A), 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 part 58. Technical questions concerning any
of the methods should be directed to the applicant. Additional
information concerning this action may be obtained from Frank F.
McElroy, Air Measurements Research Division (MD-77), National Exposure
Research Laboratory, U.S. Environmental Protection Agency, Research
Triangle Park, North Carolina 27711, (919) 541-2622.
