ENVIRONMENTAL PROTECTION AGENCY
[FRL-9997-98-ORD]
Ambient Air Monitoring Reference and Equivalent Methods;
Designation of One New Equivalent Method
AGENCY: Office of Research and Development; Environmental Protection
Agency (EPA).
ACTION: Notice of the designation of a new equivalent method for
monitoring ambient air quality.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated one new equivalent method for measuring
concentrations of ozone (O3) 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 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 equivalent
method for measuring concentrations of O3 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). This new equivalent
method for O3 is an automated method (analyzer) utilizing
the measurement principle based on UV photometry. This newly designated
equivalent method is identified as follows:
EQOA-0719-253, ``Focused Photonics Inc. AQMS-300 O3
Analyzer'' UV photometric analyzer operated the range of 0-0.5 ppm,
with 5 [micro]m, 47 mm diameter Teflon[supreg] (PTFE) filter installed,
[[Page 44300]]
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-300 User Manual.
This application for an equivalent method determination for this
O3 method was received by the Office of Research and
Development on June 10, 2019. 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 an
equivalent method.
As a designated equivalent 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 equivalent 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: July 31, 2019.

Director, National Exposure Research Laboratory.
