ENVIRONMENTAL PROTECTION AGENCY
[FRL 9949-01-ORD]
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods: Designation of One New Reference
Method and Four New Equivalent Methods
AGENCY: Environmental Protection Agency.
ACTION: Notice of the designation of a new reference method and four
new equivalent methods for monitoring ambient air quality.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with 40 CFR part 53, one new
reference method for measuring concentrations of sulfur dioxide
(SO2), four new equivalent methods for measuring
concentrations of PM2.5, PM10 and
PM10-2.5 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.

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 SO2 in ambient air
and two new equivalent methods for measuring pollutant concentrations
of PM2.5, one new equivalent method for measuring pollutant
concentrations of PM10, and one for measuring pollutant
concentrations of PM10-2.5. These designations are made
under the provisions of 40 CFR part 53, as amended on October 26, 2015
(80 FR 65291).
The new reference method for SO2 is an automated method
(analyzer) utilizing a measurement principle based on ultraviolet
fluorescence and is identified as follows:
RFSA-0616-237, ``Sutron Model 6020 Sulfur Dioxide Fluorescent
Analyzer'', operated at any of the following measurement ranges: 0-0.5
ppm, at any ambient temperature in the range of 5-40 [deg]C, at any
line voltage in the range of 90-260 VAC, at any sample flow rate in the
range of 0.4-0.8 L/min, and in accordance with the Model 6020
SO2 Analyzer Operation Manual, with or
[[Page 45285]]
without the following options: Zero/span ports for external
calibration; an optional inlet filter; or an optional second gas
measurement module co-located inside of the enclosure.
This application for a reference method determination for this
SO2 method was received by the Office of Research and
Development on April 25, 2016. This analyzer is commercially available
from the applicant, Sutron Air Quality Division, 2548 Shell Road,
Georgetown, TX 78628.
The four new PM equivalent methods are automated monitoring methods
utilizing a measurement principle based on active sampling of ambient
aerosols and contemporaneous analysis by means of a light-scattering
technique for determination of particle size and mass concentration.
These newly designated equivalent methods for PM2.5,
PM10 and PM10-2.5, are identified as follows:
EQPM-0516-236, ``Teledyne Advanced Pollution Instrumentation Model
T640 PM mass monitor,'' continuous ambient particulate monitor operated
at a volumetric flow rate of 5.0 Lpm, equipped with a TAPI 5-Lpm sample
inlet (P/N: 081050000), TAPI aerosol sample conditioner (P/N:
081040000), configured for operation with firmware version 1.0.2.126 or
later, and operated in accordance with the Teledyne Model T640
Operations Manual. This designation applies to PM2.5
measurements only.
EQPM-0516-238, ``Teledyne Advanced Pollution Instrumentation Model
T640 PM mass monitor with 640X option,'' continuous ambient particulate
monitor operated at a volumetric flow rate of 16.67 Lpm, equipped with
the louvered PM10 inlet specified in 40 CFR 50 Appendix L,
Figs. L-2 thru L-19, TAPI aerosol sample conditioner (P/N: 081040000),
configured for operation with firmware version 1.0.2.126 or later, in
accordance with the Teledyne Model T640 Operations Manual. This
designation applies to PM2.5 measurements only.
EQPM-0516-239, ``Teledyne Advanced Pollution Instrumentation Model
T640 PM mass monitor with 640X option,'' continuous ambient particulate
monitor operated at a volumetric flow rate of 16.67 Lpm, equipped with
the louvered PM10 inlet specified in 40 CFR 50 Appendix L,
Figs. L-2 thru L-19, TAPI aerosol sample conditioner (P/N: 081040000),
configured for operation with firmware version 1.0.2.126 or later, in
accordance with the Teledyne Model T640 Operations Manual. This
designation applies to PM10 measurements only.
EQPM-0516-240, ``Teledyne Advanced Pollution Instrumentation Model
T640 PM mass monitor with 640X option,'' continuous ambient particulate
monitor operated at a volumetric flow rate of 16.67 Lpm, equipped with
the louvered PM10 inlet specified in 40 CFR 50 Appendix L,
Figs. L-2 thru L-19, TAPI aerosol sample conditioner (P/N: 081040000),
configured for operation with firmware version 1.0.2.126 or later, in
accordance with the Teledyne Model T640 Operations Manual. This
designation applies to PM10-2.5 measurements only.
The four applications for equivalent method determination for the
PM candidate methods were received by the Office of Research and
Development on May 2, 2016, June 1, 2016, June 9, 2016 and June 14,
2016 respectively. The monitors are commercially available from the
applicant, Teledyne Advanced Pollution Instrumentation, Inc., 9480
Carroll Park Drive, San Diego, CA 92121-2251.
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
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 method should be
directed to the applicant.
