Office of Research and Development; Ambient Air Monitoring 
Reference and Equivalent Methods: Designation of One New Reference 
Method

AGENCY: Environmental Protection Agency.

ACTION: Notice of the designation of a new reference method for 
monitoring ambient air quality.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that the Environmental Protection 
Agency (EPA) has designated one new reference method for measuring 
concentrations of carbon monoxide (CO) in ambient air.

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 (NAAQS) 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 NAAQS. 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 reference 
method for measuring concentrations of CO in ambient air. These 
designations are made under the provisions of 40 CFR part 53, as 
amended on October 26, 2015(80 FR 65291-65468).
    The new reference method for CO is an automated method (analyzer) 
utilizing a measurement principle based on non-dispersive infrared 
(NDIR)analysis and is identified as follows:
    RFCA-0817-248, ``Sabio Model 6050 Ambient CO Analyzer'', operated 
in the measurement range of 0-50 ppm, at any ambient temperature in the 
range of 5-40 [deg]C, at any line voltage in the range of 90-260 VAC, 
at any sample flow rate in the range of 0.50-0.75 L/min, in accordance 
with the Sabio Model 6050 Ambient CO Analyzer Instruction Manual, with 
or without optional zero/span ports for external calibration, and with 
or without an optional inlet filter.
    This application for a reference method determination for this CO 
method was received by the Office of Research and Development on August 
2, 2017. This analyzer is commercially available from the applicant, 
Sutron Corporation, 21 Cypress Blvd., Suite 1130, Round Rock, TX 78665.
    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 applicant, EPA has determined, in 
accordance with Part 53, that these methods should be designated as a 
reference or equivalent method.
    As a designated reference or equivalent method, 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, each 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.

    Dated: September 19, 2017.

Director, National Exposure Research Laboratory.
