Ambient Air Monitoring Reference and Equivalent Methods:
Designation of Five New Equivalent Methods
AGENCY: Office of Research and Development; Environmental Protection
Agency (EPA).
ACTION: Notice of the designation of five 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, five
new equivalent methods, one for measuring concentrations of
PM10, one for measuring concentrations of
PM10-2.5, two for measuring PM2.5, and one for
measuring NO2 in the ambient air.
FOR FURTHER INFORMATION CONTACT: Robert Vanderpool, Human Exposure and
Atmospheric Sciences 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 methods 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.
The EPA hereby announces the designation of five new equivalent
methods for measuring pollutant concentrations in the ambient air: One
for measuring concentrations of PM10-2.5, one for measuring
concentrations of PM10, two for measuring concentrations of
PM2.5 and one for measuring concentrations of
NO2. These designations are made under the provisions of 40
CFR Part 53, as amended on August 31, 2011 (76 FR 54326-54341).
Two of the new equivalent methods for PM are automated monitoring
methods utilizing a measurement principle based on sample collection by
filtration and analysis by an inertial micro-balance that provides
direct mass measurements in near real time. Separation of the
PM10 aerosol into PM10-2.5 and PM2.5
particle size fractions is by a virtual impactor. The newly designated
equivalent methods are identified as follows:
EQPM-1013-207, ``Thermo Scientific TEOM[supreg] 1405-DF Dichotomous
Ambient Particular Monitor with FDMS[supreg],'' configured for dual
filter sampling of fine (PM2.5) and coarse particles using
the US EPA PM10 inlet specified in 40 CFR part 50 Appendix
L, Figs. L-2 thru L-19 and a virtual impactor, with a total flow rate
of 16.67 L/min, fine sample flow of 3 L/min, and coarse sample flow
rate of 1.67 L/min, and operating with firmware version 1.70 and later,
operated with or without external enclosures, and operated in
accordance with the Thermo Scientific TEOM[supreg] 1405-DF Dichotomous
Ambient Particulate Monitor Instruction Manual. This designation
applies to PM10-2.5 measurements only.
EQPM-1013-208, ``Thermo Scientific TEOM[supreg] 1405-DF Dichotomous
Ambient Particular Monitor with FDMS[supreg],'' configured for dual
filter sampling of fine (PM2.5) and coarse particles using
the US EPA PM10 inlet specified in 40 CFR part 50 Appendix
L, Figs. L-2 thru L-19 and a virtual impactor, with a total flow rate
of 16.67 L/min, fine sample flow of 3 L/min, and coarse sample flow
rate of 1.67 L/min, and operating with firmware version 1.70 and later,
operated with or without external enclosures, and operated in
accordance with the Thermo Scientific TEOM[supreg] 1405-DF Dichotomous
Ambient Particulate Monitor Instruction Manual. This designation
applies to PM10 measurements only.
Applications for the equivalent method determinations for these
candidate methods were received by the EPA Office of Research and
Development on July 26, 2011 and March 6, 2009. The monitors are
commercially available from the applicant, Thermo Fisher Scientific,
Air Quality Instruments, Environmental Instruments Division, 27 Forge
Parkway, Franklin, MA 02038.
Two of the new equivalent methods are automated monitoring methods
utilizing a measurement principle based on sample collection by
filtration and analysis by beta radiation attenuation. The newly
designated equivalent methods are identified as follows:
EQPM-1013-209, ``Met One Instruments, Inc. BAM-1022 Beta
Attenuation Mass Monitor--Outdoor PM2.5 FEM Configuration,''
configured for 24 1-hour average measurements of PM2.5 by
beta attenuation, using a glass fiber filter tape roll (460130) and a
sample flow rate of 16.67 liters/min and with the standard (BX-802) EPA
PM10 inlet (meeting 40 CFR part 50 Appendix L
specifications) and with a BGI VSCC[supreg] Very Sharp Cut Cyclone (BX-
808) particle size separator, and equipped with external enclosure BX-
922 and BX-592 ambient temperature sensor or BX-596 ambient
temperature/barometric combination sensor or BX-597 ambient
temperature/barometric pressure/relative humidity combination sensor.
Instrument must be operated in accordance with the BAM 1022 Particulate
Monitor operation manual, revision 3 or later. This designation applies
to PM2.5 measurements only.
The application for the equivalent method determination for this
candidate method was received by the EPA Office of Research and
Development on January 16, 2013. The monitor is commercially available
from the applicant, Met One Instruments, Inc., 1600 Washington Blvd.,
Grants Pass, Or 97526.
EQPM-1013-211, ``Environnement S.A. Model MP101M PM2.5
Beta Attenuation Monitor'' using a glass fiber filter tape roll,
operated at a sample flow rate of 16.67 liters/min for 24-hour average
measurements of PM2.5, configured with the standard EPA
PM10 inlet (meeting 40 CFR part 50 Appendix L
specifications) associated with a BGI VSCC[supreg] Very Sharp Cut
Cyclone particle size separator and using a temperature regulated

The new equivalent method for NO2 is an automated method
(analyzer) utilizing the principle of Cavity Attenuated Phase Shift
spectroscopy and the calibration procedure specified in the operation
manual. The newly designated equivalent method is identified as
follows:

method was received by the Office of Research and Development on
November 29, 2012. This analyzer model is commercially available from
the applicant, Environment S.A., 111 bd Robespierre, 78300 POISSY,
France.
Test monitors representative of these methods have been tested in
accordance with the applicable test procedures specified in 40 CFR Part
53, as amended on August 31, 2011. After reviewing the results of those
tests and other information submitted in the applications, EPA has
determined, in accordance with Part 53, that these methods should be
designated as equivalent methods.
As designated equivalent methods, 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,
the methods must be used in strict accordance with the operation or
instruction manuals associated with the methods and subject to any
specifications and limitations (e.g., configuration or operational
settings) specified in the applicable designated descriptions (see the
identification of the methods above).
Use of the methods 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-08-003, December, 2008. 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 should be reported to:
Director, Human Exposure and Atmospheric Sciences Division (MD-E205-
01), National Exposure Research Laboratory, U.S. Environmental
Protection Agency, Research Triangle Park, North Carolina 27711.
Designation of these new 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 applicant.
