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 methods 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.
    The EPA hereby announces the designation of five new equivalent 
methods for measuring pollutant concentrations in the ambient air: One 
for measuring concentrations of PM10-2.5, one for measuring 
concentrations of PM10, two for measuring concentrations of 
PM2.5 and one for measuring concentrations of 
NO2. These designations are made under the provisions of 40 
CFR Part 53, as amended on August 31, 2011 (76 FR 54326-54341).
    Two of the new equivalent methods for PM are automated monitoring 
methods utilizing a measurement principle based on sample collection by 
filtration and analysis by an inertial micro-balance that provides 
direct mass measurements in near real time. Separation of the 
PM10 aerosol into PM10-2.5 and PM2.5 
particle size fractions is by a virtual impactor. The newly designated 
equivalent methods are identified as follows:
    EQPM-1013-207, ``Thermo Scientific TEOM[supreg] 1405-DF Dichotomous 
Ambient Particular Monitor with FDMS[supreg],'' configured for dual 
filter sampling of fine (PM2.5) and coarse particles using 
the US EPA PM10 inlet specified in 40 CFR part 50 Appendix 
L, Figs. L-2 thru L-19 and a virtual impactor, with a total flow rate 
of 16.67 L/min, fine sample flow of 3 L/min, and coarse sample flow 
rate of 1.67 L/min, and operating with firmware version 1.70 and later, 
operated with or without external enclosures, and operated in 
accordance with the Thermo Scientific TEOM[supreg] 1405-DF Dichotomous 
Ambient Particulate Monitor Instruction Manual. This designation 
applies to PM10-2.5 measurements only.
