SUPPLEMENTARY INFORMATION: In accordance with regulations at 40 CFR 
part 53, the EPA examines various methods for monitoring the 
concentrations of certain pollutants in the ambient air. Methods that 
are determined to meet specific requirements for adequacy are 
designated as either reference or equivalent methods, thereby 
permitting their use under 40 CFR part 58 by States and other agencies 
in determining attainment of the National Ambient Air Quality 
Standards. The EPA is hereby announcing that it has received five new 
applications for reference or equivalent method determinations under 40 
CFR part 53. Publication of a notice of receipt of such applications is 
required by section 53.5.
    On February 3, 1998, EPA received two applications from the 
Rupprecht and Patashnick Company, Incorporated, 25 Corporate Circle, 
Albany, New York 12203 to determine if methods based on that Company's 
Partisol1-FRM Model 2000 (single) and Partisol-
Plus Model 2025 (sequential) PM-10 Air Samplers should be designated as 
reference methods for PM10. The EPA received an application 
on February 24, 1998, from Advanced Pollution Instrumentation, 
Incorporated, 6565 Nancy Ridge Drive, San Diego, California 92121 for 
an equivalent method determination for their Model 400A UV Photometric 
Ozone Analyzer. An application was received on March 26, 1998 from 
Horiba Instruments Incorporated, 17671 Armstrong Avenue, Irvine, 
California 92614 for an equivalent method determination for Horiba's 
Model APSA-360ACE ambient SO2 monitor. And on April 14, 
1998, the EPA received an application from DKK Corporation, 4-13-14, 
Kichijoji Kitamachi, Musashino-shi, Tokyo, 180-8630, Japan for a 
reference method determination for DKK's Model GLN-114E Nitrogen Oxides 
Analyzer.
    If, after appropriate technical study, the Administrator determines 
that any or all of these methods should be designated as either 
reference or equivalent methods, notice thereof will be published in a 
subsequent issue of the Federal Register.
Thomas A. Clark,
Acting Assistant Administrator for Research and Development.
