ENVIRONMENTAL PROTECTION AGENCY
Ambient Air Monitoring Reference and Equivalent Methods;
Designation of One New Reference Method
AGENCY: Office of Research and Development; Environmental Protection
ACTION: Notice of the designation of a new reference method for
monitoring ambient air quality.
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated one new reference method for measuring
concentrations of nitrogen dioxide (NO2) in ambient air.
FOR FURTHER INFORMATION CONTACT: Robert Vanderpool, Exposure Methods
and Measurements Division (MD-D205-03), National Exposure Research
Laboratory, U.S. EPA, Research Triangle Park, North Carolina 27711.
Phone: 919-541-7877. Email: Vanderpool.Robert@epa.gov.
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 (NAAQS) 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 or equivalent methods (as applicable), thereby permitting
their use under 40 CFR part 58 by States and other agencies for
determining compliance with the NAAQS. A list of all reference or
equivalent methods that have been previously designated by EPA may be
found at http://www.epa.gov/ttn/amtic/criteria.html.
The EPA hereby announces the designation of one new reference
method for measuring concentrations of NO2 in ambient air.
This designation is made under the provisions of 40 CFR part 53, as
amended on October 26, 2015 (80 FR 65291-65468).
The new reference method for NO2 is an automated method
(analyzer) utilizing the measurement principle based on gas phase
chemiluminescence. This newly designated reference method is identified
RFNA-0118-249, ``Environnement S. A. Model AC32e and AC32e*
Chemiluminescent NO, NOX, NO2 Analyzer,''
operated with user selectable ranges of 0-1 ppm or 0-10 ppm, at any
temperature in the range of 0 [deg]C to 40 [deg]C, equipped with a 5-
micron PTFE sample inlet filter, molybdenum NOX converter
operating at 340 [deg]C, heated catalytic ozone scrubber, external
pump, operating with a sample flow rate of 0.66 Lpm (1.00 Lpm with
optional sample dryer), with an ozone flow rate of 0.06 Lpm, and
operating from a 115V/60Hz, 230V/50Hz power source. Includes 7'' touch
screen and USB and Ethernet outputs. Model AC32e* does not contain
touch screen and communicates via user-provided computer, smartphone,
or tablet. Analyzer operated and maintained in accordance with the
Model AC32e Technical Manual.
This application for a reference method determination for this
NO2 method was received by the Office of Research and
Development on December 6, 2017. This analyzer is commercially
available from the applicant, Environment S.A., 111, bd Robespierre,
78300 Poissy, France.
A representative test analyzer was tested in accordance with the
applicable test procedures specified in 40 CFR part 53, as amended on
October 26, 2015. After reviewing the results of those tests and other
information submitted by the applicant, EPA has determined, in
accordance with part 53, that this method should be designated as a
As a designated reference method, this 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,
this 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 designated method description (see the
identification of the method above).
Use of the method also should 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, Ambient Air Quality Monitoring
Program,'' EPA-454/B-13-003, (both
available at http://www.epa.gov/ttn/amtic/qalist.html). 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
Consistent or repeated noncompliance with any of these conditions
should be reported to: Director, Exposure Methods and Measurements
Division (MD-E205-01), National Exposure Research Laboratory, U.S.
Environmental Protection Agency, Research Triangle Park, North Carolina
Designation of this reference 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
