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 reference 
method for measuring pollutant concentrations of PM10, one 
new reference method for measuring pollutant concentrations of 
PM10-2.5, one for measuring ozone (O3), and three 
new equivalent methods for measuring pollutant concentrations of 
PM2.5 in the 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 O3 is an automated method 
that utilizes a measurement principle based on non-dispersive 
ultraviolet absorption photometry. The newly designated reference 
method for O3 is identified as follows:

    RFOA-0216-230, ``Teledyne Advanced Pollution Instrumentation, 
Model 265E or T265 Chemiluminescence Ozone Analyzer,'' operated on 
any full scale range between 0-100 ppb and 0-1000 ppb, with any 
range mode (Single, Dual, or AutoRange), at any ambient temperature 
in the range of 5 [deg]C to 40 [deg]C, and with a TFE filter or a 
Kynar[supreg] DFU in the sample air inlet, operated with a sample 
flow rate of 500  50 cm\3\/min (sea level), with the 
dilution factor set to 1, with Temp/Press compensation ON, and in 
accordance with the appropriate associated instrument manual, and 
with or without any of the following options: Internal or external 
sample pump, Sample/Cal valve option, Rack mount with or without 
slides, analog input option, 4-20 mA isolated current loop output. 
Note 2 applies to the following Teledyne Advanced Pollution 
Instrumentation Models 265E and T265.

    The application for a reference method determination for this 
candidate method was received by the Office of Research and Development 
on February 2, 2016. The analyzer is commercially available from the 
applicant, Teledyne Advanced Pollution Instrumentation, Inc., 9480 
Carroll Park Drive, San Diego, CA 92121-2251.
    The new reference method for PM10 is a manual monitoring 
method based on a particular PM10 sampler and is identified 
as follows:

    RFPS-0216-231, ``Met One Instruments, Inc. E-FRM,'' configured 
for filter sampling of ambient particulate matter using the US EPA 
PM10 inlet specified in 40 CFR part 50 appendix L, Figs. 
L-2 thru L-19, with a flow rate of 16.67 L/min, using 47 mm PTFE 
membrane filter media, and operating with firmware version R2.0.1 
and later, and operated in accordance with the Met One E-FRM 
PM10 operating manual. This designation applies to 
PM10 measurements only.

    The new PM10-2.5 reference method utilizes a pair of 
filter samplers than 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-0315-
221 and RFPS-0216-231, respectively. The newly designated 
PM10-2.5 sampler is identified as follows:

    RFPS-0316-232, ``Met One Instruments, Inc. E-FRM-PM10 
and E-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-FRM samplers, with one being the 
E-FRM PM2.5 sampler (RFPS-0315-221) and the other being 
the E-FRM PM10 sampler (RFPS-0216-231). 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-FRM instruction manual. This designation applies to 
PM10-2.5 measurements only.

    One newly designated equivalent method for PM2.5 is a 
manual monitoring method based on a particular PM2.5 sampler 
and is identified as follows:

    EQPS-0316-235, ``Met One Instruments, Inc. E-FRM,'' configured
