ENVIRONMENTAL PROTECTION AGENCY

[FRL-9955-68-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 40 CFR part 53, 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: Vanderpool.Robert@epa.gov.

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 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) utilizing the measurement principle based on gas phase 
chemiluminescence reaction of nitric oxide (NO) with ozone, using a 
photolytic NO2 to NO converter and the calibration procedure 
specified in the operation manual. This newly designated equivalent 
method is identified as follows:

[[Page 85562]]

    EQNA-1016-241, ``Teledyne Advanced Pollution Instrumentation 
Model T200P chemiluminescence Nitrogen Oxides Analyzer,'' operated 
on any full scale range between 0-50 ppb and 0-1000 ppb, with a PTFE 
filter element or a Kynar[supreg] DFU installed in the filter 
assembly, with any range mode (Single or Dual), at any operating 
temperature in the range of 15[deg]C to 35[deg]C, with the high 
efficiency photolytic converter, with software Temperature and 
Pressure compensation ON, in accordance with the associated 
instrument manual; and with or without any of the following options: 
Zero/Span valves, internal Zero/Span permeation oven (IZS), Nafion-
type sample gas conditioner, external communication and data 
monitoring interfaces; and the NumaViewTM software.

    This application for an equivalent method determination for this 
candidate method was received by the Office of Research and Development 
on September 19, 2016. This analyzer is commercially available from the 
applicant, Teledyne Advanced Pollution Instrumentation, Inc., 9480 
Carroll Park Drive, San Diego, CA 92121-2251.
    A representative test analyzer has 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 this method should be designated as an 
equivalent method.
    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, 
this 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 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.
