BILLING CODE 6560-50-P 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 (NO <sup>2</sup> ) 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 NO <sup>2</sup> 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 NO <sup>2</sup> is an automated method (analyzer) utilizing the measurement principle based on gas phase chemiluminescence reaction of nitric oxide
(NO)with ozone, using a photolytic NO <sup>2</sup> to NO converter and the calibration procedure specified in the operation manual. This newly designated equivalent method is identified as follows: 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® DFU installed in the filter assembly, with any range mode (Single or Dual), at any operating temperature in the range of 15°C to 35°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 NumaView TM 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. Dated: November 18, 2016. Jennifer Orme-Zavaleta, Director, National Exposure Research Laboratory. [FR Doc. 2016-28562 Filed 11-25-16; 8:45 am]
