ENVIRONMENTAL PROTECTION AGENCY
[FRL 9918-79-ORD]
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods: Designation of Two New Reference
Methods and Two New Equivalent Methods
AGENCY: Environmental Protection Agency.
ACTION: Notice of designation of two reference methods and two
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, two new
reference methods and two new equivalent methods. The reference methods
include one for measuring PM2.5, and one for measuring
PM10-2.5 in the ambient air. The two equivalent methods are
one for measuring carbon monoxide (CO) and one for measuring ozone
(O3) 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 one new reference
method for measuring PM2.5, one new reference method for
measuring PM10-2.5, one new equivalent method for measuring
concentrations of carbon monoxide (CO), and one equivalent method for
measuring ozone (O3) in the ambient air. These designations
are made under the provisions of 40 CFR part 53, as amended on August
31, 2011 (76 FR 54326-54341).
The new reference method for PM2.5 is a manual
monitoring method based on a particular PM2.5 sampler and is
identified as follows:
RFPS-1014-219, ``Tisch Environmental Model TE-Wilbur2.5
PM2.5 Low-Volume Air Particulate Sampler,'' configured as a
PM2.5 reference method, with firmware version 1.70 or later
and a TE-PM10-D PM10 size-selective inlet as
specified in 40 CFR 50 Appendix L Figs. L-2 thru L-19, with either a
BGI VSCCTM Very Sharp Cut Cyclone particle size separator or
WINS impactor, and operated for 24 sample periods at a flow rate of
16.67 L/min, using 47 mm PTFE membrane filter media, and in accordance
with the Tisch Environmental Model TE-Wilbur2.5 PM2.5 Low-
Volume Air Particulate Sampler instruction manual and with the
requirements and sample collection filters as specified in 40 CFR part
50, Appendix L.
The new PM10-2.5 reference method utilizes a pair of
filter samplers than have been designated individually as reference
methods, one for PM2.5 and the other one for
PM10, and have been shown to meet the requirements specified
in Appendix O of 40 CFR part 50. The PM2.5 and
PM10 samplers are designated as reference methods RFPS-1014-
219 and RFPS-0714-216, respectively. The newly designated
PM10-2.5 sampler is identified as follows:
RFPS-1014-220, ``Tisch Environmental Model TE-Wilbur Low-Volume Air
Particulate Sampler Pair'' for the determination of coarse particulate
matter as PM10-2.5, consisting of a pair of Tisch
Environmental Model TE-Wilbur samplers, with one being the TE-Wilbur
2.5 PM2.5 sampler (RFPS-1014-219) and the other being a TE-
Wilbur 10 PM10 sampler (RFPS-0714-216), and operated in
accordance with the associated TE-Wilbur instruction manual. This
designation applies to PM10-2.5 measurements only.
The application for reference method determination for the
PM2.5 method was received by the Office of Research and
Development on September 29, 2014 and the PM10-2.5 method
application was received on October 8, 2014. These monitors are
commercially available from the applicant, Tisch Environmental, Inc.,
145 S. Miami Avenue, Village of Cleves, OH 45002.
The newly designated equivalent method for CO is a mercury
replacement-UV photometric method and is identified as follows:
EQCA-0814-217, ``Peak Laboratories, Model 910-170 Carbon Monoxide
Analyzer'', (Mercury replacement--UV photometric method) operated on
any
[[Page 65393]]
full scale range between 0-50 ppm, at any operating temperature from 20
[deg]C to 30 [deg]C, using a back-flushing GC scrubber, 99.9999%
nitrogen carrier gas at a gas pressure of 60-80 psig, with a column
temperature of 105 [deg]C, and a detector temperature of 265 [deg]C;
inlet flow of 20-100 mL/min; in accordance with the associated
instrument manual, and with or without any of the following options:
Rack mount kit, internal sample pump, 4-20 mA output module, particle
filter, and data collection software.
The application for equivalent method determination for the CO
method was received by the Office of Research and Development on
January 3, 2011. This monitor is commercially available from the
applicant, Peak Laboratories, LLC, 2330 Old Middlefield Way Suite 10,
Mountain View, CA 94043.
One new O3 equivalent method is an automated monitoring
method (analyzer) utilizing a measurement principle based on
ultraviolet absorption photometry. The newly designated equivalent
method is identified as follows:
EQOA-0914-218, ``2B Technologies Model 106-L or OEM-106-L Ozone
Monitor'' operated in a range of 0-0.5 ppm in an environment of 20-30
[deg]C, with temperature and pressure compensation, internal dewLine
for humidity control, using a 1 minute average, with a 12V DC source
supplied by a 100-240V AC power adapter, operated according to the
Model 106 Ozone Monitor Operation Manual and with or without the
following: Cigarette lighter adapter or a 12V DC battery for portable
operation, external PTFE or PVDF inlet filter and holder, USB data port
with computer cable.
The application for equivalent method determination for the
O3 method was received by the Office of Research and
Development on June 24, 2014. This monitor is commercially available
from the applicant, 2B Technology, Inc., 2100 Central Ave., Suite 105,
Boulder, CO 80303.
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 application, EPA has
determined, in accordance with part 53, that these methods should be
designated as equivalent methods.
As designated reference and 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 manual associated with the method and
subject to any specifications and limitations (e.g., configuration or
operational settings) specified in the applicable designated method
description (see the identification of the method 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 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.
Dated: October 24, 2014.
