ENVIRONMENTAL PROTECTION AGENCY
[FRL-9966-90-ORD]
Ambient Air Monitoring Reference and Equivalent Methods:
Designation of Three New Reference Methods
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated three new reference methods for measuring
concentrations of PM2.5, PM10, and
PM10-2.5 in the 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 (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 three new reference
methods for measuring concentrations of PM2.5,
PM10, and PM10-2.5 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 specific PM2.5 sampler and is
identified as follows:
RFPS-0717-245, ``Met One Instruments, Inc. E-SEQ-FRM,'' sequential
sampler configured for multi-event filter sampling of ambient
[[Page 44613]]
particulate matter using the U.S. EPA PM10 inlet specified
in 40 CFR part 50, Appendix L, Figs. L-2 thru L-19, equipped with
either a Mesa Laboratories VSCCTM cyclone or WINS
PM2.5 fractionator, with a flow rate of 16.67 L/min, using
47 mm PTFE membrane filter media, and operating with firmware version
R1.1.0 and later, and operated in accordance with the Met One E-SEQ-FRM
PM2.5 operating manual. This designation applies to
PM2.5 measurements only.
The new reference method for PM10 is a manual monitoring
method based on a specific PM10 sampler and is identified as
follows:
RFPS-0717-246, ``Met One Instruments, Inc. E-SEQ-FRM,'' sequential
sampler configured for multi-event filter sampling of ambient
particulate matter using the U.S. EPA PM10 inlet specified
in 40 CFR part 50, Appendix L, Figs. L-2 thru L-19, equipped with
either a Mesa Laboratories VSCCTM cyclone or WINS
PM2.5 fractionator, with a flow rate of 16.67 L/min, using
47 mm PTFE membrane filter media, and operating with firmware version
R1.1.0 and later, and operated in accordance with the Met One E-SEQ-FRM
PM10 operating manual. This designation applies to
PM10 measurements only.
The new PM10-2.5 reference method utilizes a pair of
filter samplers that 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-0717-
245 and RFPS-0717-246, respectively. The newly designated
PM10-2.5 sampler is identified as follows:
RFPS-0717-247, ``Met One Instruments, Inc. E-SEQ-FRM
PM10 and E-SEQ-FRM PM2.5 Sampler Pair'' for the
determination of coarse particulate matter as PM10-2.5,
consisting of a pair of Met One Instruments, Inc. E-SEQ-FRM samplers,
with one being the E-SEQ-FRM PM2.5 sampler (RFPS-0717-245)
and the other being the E-SEQ-FRM PM10 sampler (RFPS-0717-
246). The units are to be collocated to within 1-4 meters of one
another and sample concurrently. Both units are operated in accordance
with the associated E-SEQ-FRM 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 May 17, 2017, the PM10 method application was
received on June 5, 2017, and the PM10-2.5 method was
received on July 25, 2017. These monitors are commercially available
from the applicant, Met One Instruments, Inc., 1600 Washington Blvd.,
Grants Pass, OR 97526.
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 reference methods. The information in the applications
will be kept on file, either at EPA's National Exposure Research
Laboratory, Research Triangle Park, North Carolina 27711 or in an
approved archive storage facility, and will be available for inspection
(with advance notice) to the extent consistent with 40 CFR part 2
(EPA's regulations implementing the Freedom of Information Act).
As designated reference 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, 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 new reference 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.
Dated: August 16, 2017.

Deputy Director, National Exposure Research Laboratory.
