Ambient Air Monitoring Reference and Equivalent Methods;
Designation of One New Reference Method
AGENCY: Environmental Protection Agency (EPA).
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 carbon monoxide (CO) in ambient air.
FOR FURTHER INFORMATION CONTACT: Robert Vanderpool, Exposure Methods
and Measurement Division (MD-D205-03), National Exposure Research
Laboratory, U.S. EPA, Research Triangle Park, North Carolina 27711.
Phone: 919-541-7877. Email: [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
[[Page 24509]]
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 CO 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 CO is an automated method (analyzer)
utilizing the measurement principle based on non-dispersive infrared
(NDIR) spectroscopy. This newly designated reference method is
identified as follows:
RFCA-0419-252, ``Focused Photonics Inc. AQMS-400 CO Analyzer'' non-
dispersive infrared (NDIR) analyzer operated in the range of 0-50 ppm,
with 5 [micro]m, 47 mm diameter Teflon[supreg](PTFE) filter installed,
operated at temperatures between 20 [deg]C and 30 [deg]C, at nominal
input line voltage of 22010% VAC and frequency of 50 Hz, at
a nominal sampling flow rate of 80080 cc/min, and operated
according to the FPI AQMS-400 User Manual.''
This application for a reference method determination for this CO
method was received by the Office of Research and Development on April
10, 2017. This analyzer is commercially available from the applicant,
Focused Photonics Inc. (FPI), 760 Bin`an Road, Binjiang District,
Hangzhou, Zhejiang, China.
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
reference method.
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 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
27711.
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
the applicant.
Dated: May 10, 2019.

Director, National Exposure Research Laboratory.
