ENVIRONMENTAL PROTECTION AGENCY
[FRL-10020-31-ORD]
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 sulfur dioxide (SO2), and one new
equivalent method for measuring concentrations of particulate matter
(PM10) in ambient air.
FOR FURTHER INFORMATION CONTACT: Robert Vanderpool, Air Methods and
Characterization Division (MD-D205-03), Center for Environmental
Measurements and Modeling, 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 reference
method for measuring concentrations of SO2 in ambient air
and one new equivalent method for measuring concentrations of
PM10 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 SO2 is an automated method
(analyzer) utilizing the measurement principle based on UV
fluorescence. This newly designated reference method is identified as
follows:
RFSA-1120-257, ``KENTEK Inc. Model MEZUS 110 SO2
Analyzer,'' UV fluorescence analyzer operated in a range of 0-0.5 ppm,
with 0.5 [micro]m, 47 mm diameter Teflon[supreg] filter installed,
operated at temperatures between 20[deg] C and 30[deg] C, at a nominal
sampling flow rate of 800 cc/min, using a 5 minute averaging time, with
either 105VAC-125VAC or 200VAC-240VAC input power options installed,
280-watt power consumption, equipped with 7 inch LCD touch screen
display, and operated according to the KENTEK Inc. Model Mezus 110
Sulfur Dioxide Analyzer User's Instruction Manual.
This application for a reference method determination for this
SO2 method was received by the Office of Research and
Development on July 21, 2020. This analyzer is commercially available
from the applicant, KENTEK Inc., Hanshin S. Meca Room #526, 65 Techno
3-ro, Yuseong-gu, Daejeon, Republic of Korea, 34016.
The new equivalent method for PM10 is an automated
method (monitor) utilizing the measurement principle based on Beta
Attenuation or [beta]-ray monitoring. This newly designated equivalent
method is identified as follows:
EQPM-0121-258, ``Focused Photonics Inc. BPM-200 PM10
Monitor,'' [beta]-ray monitor operated in the following concentration
ranges: 0-1 mg/m\3\, 0-2 mg/m\3\, 0-5 mg/m\3\, or 0-10 mg/m\3\,
analyzing ambient conditions temperatures between -30[deg] C to 50[deg]
C, while the monitor can operate in a conditioned space between 0[deg]
C to 50[deg] C. The unit is operated for 24-hour average measurements,
with the FPI P/N 6150138000X EPA PM10 inlet, glass fiber
filter tape with axial inner diameter of 40mm (GCY00003900), the 220VAC
50Hz power supply, the FPI P/N 6150139000X Atmospheric Temperature
Unit, the 6100050000X Air heating unit for maintaining moisture at
about 35% and no [Delta]T control, the FPI P/N GCX00013700 filter, the
FPI P/N 6102182000X internal calibration device, 290508D00A Main Board,
and 2910510B00X Interface board display. Instrument must be operated in
accordance with the appropriate instrument manual and with software
(firmware) version AQMSPlus.P005.V01A.US001.
This application for an equivalent method determination for this
PM10 method was received by the Office of Research and
Development on October 13, 2020. This monitor is commercially available
from the applicant, Focused Photonics Inc. (FPI), 760 Bin`an Road,
Binjiang District, Hangzhou, Zhejiang, China.

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 applicants, EPA has determined, in
accordance with 40 CFR 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, Air Methods and Characterization
Division (MD-D205-03), Center for Environmental Measurements and
Modeling, U.S. Environmental Protection Agency, Research Triangle Park,
North Carolina 27711.
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 methods should be
directed to the applicants.
Timothy Watkins,
Director, Center for Environmental Measurements and Modeling.
