ENVIRONMENTAL PROTECTION AGENCY
[FRL-9960-60-ORD]
Office of Research and Development; Ambient Air Monitoring
Reference and Equivalent Methods: Designation of One New Equivalent
Method
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of the designation of a new equivalent method for
monitoring ambient air quality.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with applicable Federal
regulations, one new equivalent method for measuring concentrations of
nitrogen dioxide (NO2) 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.
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 or equivalent methods (as applicable), thereby permitting
their use under 40 CFR part 58 by States and other agencies for
determining
[[Page 21996]]
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 equivalent
method for measuring concentrations of NO2 in ambient air.
This designation is made under the provisions of 40 CFR part 53, as
amended on October 26, 2015 (80 FR 65291-65468).
The new equivalent method for NO2 is an automated method
(analyzer) and is identified as follows:
EQNA-0217-243, ``2B Technologies, Model 405 nm NO2/
NO/NOX Monitor,'' operated in a range of 0-500 ppb,
operated at temperatures between 20 [deg]C and 30 [deg]C, with
temperature and pressure compensation, with internal DewLine for
humidity control, with averaging times from 5 seconds to 1 hour,
with a 110-220V AC power adapter or a 12V DC source, operated in
accordance with the instrument manual, and with or without the
following: Auto zeroing, external PTFE inlet filter and holder,
cigarette lighter adapter or a 12V DC battery for portable
operation, serial data communication, 0-2.5V or scalable analog
output, external communication and monitoring interfaces, internal
data logger, removable memory device for data recording and backup.
An application for the equivalent method determination for this
candidate method was received by the EPA on January 23, 2017. This
analyzer is commercially available from the applicant, 2B Technologies,
2100 Central Ave., Suite 105, Boulder, CO 80301.
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 in the respective
applications, EPA has determined, in accordance with Part 53, that this
method should be designated as a reference method or equivalent method,
as appropriate.
As a designated equivalent method, this method is 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 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 this new equivalent method 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: March 6, 2017.
Jennifer Orme-Zavaleta,
Director, National Exposure Research Laboratory.
