ENVIRONMENTAL PROTECTION AGENCY
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods: Designation of One New Reference
Method and One New Equivalent Method
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of the designation of one new reference method and one
new equivalent 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 carbon monoxide (CO), and one new equivalent method
for measuring concentrations of nitrogen dioxide (NO2) in

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) 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 NAAQSs. 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 CO in ambient air and one new
equivalent method for measuring concentrations of NO2 in
ambient air. These designations are made under the provisions of 40 CFR
part 53, as amended on October 26, 2015 (80 FR 65291-65468).
The new reference method for CO is an automated method (analyzer)
utilizing a measurement principle based on non-dispersive infrared
(NDIR) analysis and is identified as follows:
RFCA-0317-244, ``Kentek Mezus Model 310 Carbon Monoxide Analyzer''
non-dispersive infrared (NDIR) analyzer operated in the measurement
range of 0-50 ppm, with 0.5 [micro]m, 47 mm diameter Teflon[supreg]
filter installed, operated at any ambient temperatures between 20
[deg]C and 30 [deg]C, at nominal input line voltages of 110 VAC or 220
VAC and frequencies of 50 to 60 Hz, with temperature and pressure
compensation, at a nominal sampling flow rate of 800 cc/min, and
operated according to the Kentek Mezus 310 CO User's Instruction
This application for a reference method determination for this CO
method was received by the Office of Research and Development on May
25, 2016. This analyzer is commercially available from the applicant,
Kentek Environmental Technology, Hanshin S Meca Room #526, 65 Techbi 3-
ro, Yuseong-gu, Daejeon, Republic of Korea, 34016.
The new equivalent method for NO2 is an automated method
(analyzer) utilizing a measurement principle based on cavity attenuated
phase shift (CAPS) spectroscopy and is identified as follows:
EQNA-0217-242, ``Ecotech Serinus 60 NO2 CAPS (Cavity
Attenuated Phase Shift) Analyzer'' operated at temperatures between 20
[deg]C and 45 [deg]C, a line voltage between 80V and 260V, and with or
without any of the following options: Rack mounts, internal pump,
internal permeation device, high pressure calibration ports, Ethernet
output. The following menu choices must be selected: Control Loop--
Enabled; Diagnostic Mode--Operate; Pres/Temp/Flow Compensation--
Enabled; Span Compensation--Disabled, and operated according to the
Serinus 60 User Manual.
This application for an equivalent method determination for this
NO2 method was received by the Office of Research and
Development on January 11, 2017. This analyzer is commercially
available from the applicant, Ecotech Pty. Ltd., 1492 Ferntree Gully
Rd., Knoxfield, Victoria, 3180, Australia.
Representative test analyzers have been 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 these methods should be designated as a
reference or equivalent method.
As a designated reference or equivalent method, these methods are
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 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 part 58.
Consistent or repeated noncompliance with any of these conditions
should be reported to: Director, Exposure Methods and Measurement
Division (MD-E205-01), National Exposure Research Laboratory, U.S.
Environmental Protection Agency, Research Triangle Park, North Carolina
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 the method should be
directed to the applicant.
Dated: May 17, 2017.
Director, National Exposure Research Laboratory.
