Ambient Air Monitoring Reference and Equivalent Methods;
Reference Method Designation
Notice is hereby given that EPA, in accordance with 40 CFR part 53,
has designated another reference method for the measurement of ambient
concentrations of nitrogen dioxide. The new reference method is an
automated method (analyzer) which utilizes the measurement principle
(gas phase chemiluminescence) and calibration procedure specified in
appendix F of 40 CFR part 50. The new designated method is identified
as follows:
RFNA-0795-104, ``Environment S. A. Model AC 31 M Chemiluminescent
Nitrogen Oxide Analyzer,'' operated with a full scale range of 0-500
ppb, at any temperature in the range of 15 deg.C to 35 deg.C, with 5-
micron PTFE sample particulate filter, with the following software
settings: Automatic response time ON, Minimum response time set to 60
seconds (RT2), and with or without any of the following
options:
Internal Permeation Oven
Connection for Silica Gel Dryer
RS232-422 interface
EV34 valve
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 and
any of the following voltage ranges: 98-126 Vac (115 nominal) and
195-246 Vac (230 volts 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, California 93401. A notice
of receipt of application for this method appeared in the Federal
Register, Volume 60, January 31, 1995, page 5919.
A test analyzer representative of this method has been tested by
the 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 applicant, EPA has determined, in
accordance with part 53, that this method should be designated as a
reference method. The information submitted by the applicant 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 method, this method is acceptable for use
by States and other air monitoring agencies under 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
limitations (e.g., operating range) specified in the applicable
designation (see description of the method 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 part 58 (Modifications of Methods by
Users).
In general, this designation applies to any analyzer which is
identical to the analyzer described in the designation. In many 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 designation status at a modest cost. The manufacturer
should be consulted to determine the feasibility of such upgrading.
Part 53 requires that sellers of designated methods 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 analyzers
has been canceled or if adjustment of the analyzers 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 he has received
[[Page 38327]]
notice under 40 CFR 53.14(c) that the original designation or a new
designation applies to the method as modified or until he 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, Department E (MD-
77), U.S. Environmental Protection Agency, Research Triangle Park,
North Carolina 27711.
Designation of this reference method will provide assistance to the
States in establishing and operating their air quality surveillance
systems under part 58. Technical questions concerning the method should
be directed to the manufacturer. 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.
