Ambient Air Monitoring Reference and Equivalent Methods: 
Designation of a new Equivalent Method for O3

AGENCY: Environmental Protection Agency.

ACTION: Notice of designation and receipt of application.

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

SUMMARY: Notice is hereby given that the Environmental Protection 
Agency (EPA) has designated, in accordance with 40 CFR part 53, a new 
equivalent method for measuring concentrations of O3 in 
ambient air. Notice is also given that EPA has received a new applica-
tion for an equivalent method determination from Andersen Instruments, 
Incorporated, Smyrna, Georgia, for a PM10 monitor.

FOR FURTHER INFORMATION CONTACT: Frank F. McElroy, Human Exposure and 
Atmospheric Sciences Division (MD-46), National Exposure Research 
Laboratory, U.S. EPA, Research Triangle Park, North Carolina 27711, 
Phone: (919) 541-2622, email: [email protected].

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 
for determining attainment of the National Ambient Air Quality 
Standards. EPA hereby announces the designation of a new equivalent 
method for measuring O3 in ambient air. This designation is 
made under the provisions of 40 CFR part 53, as amended on July 18, 
1997 (62 FR 38764).
    The new equivalent method for O3 is an automated method 
which utilizes the measurement principle based on UV photometry. The 
newly designated method is identified as follows:

    EQOA-0200-134, ``DKK Corporation Model GUX-113E Ozone 
Analyzer,'' operated at any temperature in the range of

[[Page 11309]]

15  deg.C to 35  deg.C and on any of the following measurement 
ranges: 0-0.100 ppm, 0-0.200 ppm, 0-0.5 ppm, or 0-1.000 ppm.

    An application for an equivalent method determination for the 
method based on this DKK analyzer was received by the EPA on December 
2, 1999. The analyzer is available commercially from the applicant, DKK 
Corporation, 4-13-14, Kichijoji Kitamachi, Musashino-shi, Tokyo, 180, 
JAPAN.
    A test analyzer representative of this method has been tested by 
the applicant in accordance with the test procedures specified in 40 
CFR part 53 (as amended on July 18, 1997). 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. The information submitted by the 
applicant will be kept on file at EPA's National Exposure Research 
Laboratory, Research Triangle Park, North Carolina 27711 and will be 
available for inspection to the extent consistent with 40 CFR part 2 
(EPA's regulations imple-menting the Freedom of Information Act).
    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, 
the method must be used in strict accordance with the operation or 
instruction manual associated with the method and the specifications 
and limitations (e.g., operating temperature or measurement range) 
specified in the applicable designation method description (see the 
identification of the method above). Use of the method should also be 
in general accordance with the guidance and recommendations of 
applicable sections of the ``Quality Assurance Handbook for Air 
Pollution Measurement Systems, Volume II, EPA/600/R-94/0386.'' Vendor 
modifications of a designated reference or equivalent method used for 
purposes of part 58 are permitted only with prior approval of the EPA, 
as provided in part 53. Provisions concerning modification of such 
methods by users are specified under section 2.8 of appendix C to 40 
CFR part 58 (Modifications of Methods by Users).
    In general, a method designation applies to any sampler or analyzer 
which is identical to the sampler or analyzer described in the 
application for designation. In some cases, similar samplers or 
analyzers manufactured prior to the designation may be upgraded (e.g., 
by minor modification or by substitution of the approved operation or 
instruction manual) so as to be identical to the designated method and 
thus achieve designated status at a modest cost. The manufacturer 
should be consulted to determine the feasibility of such upgrading.
    Part 53 requires that sellers of designated reference or equivalent 
method analyzers or samplers comply with certain conditions. These 
conditions are given in 40 CFR 53.9 and are summarized below:
    (a) A copy of the approved operation or instruction manual must 
accompany the sampler or analyzer when it is delivered to the ultimate 
purchaser.
    (b) The sampler or analyzer must not generate any unreasonable 
hazard to operators or to the environment.
    (c) The sampler or analyzer must function within the limits of the 
applicable performance specifications given in parts 50 and 53 for at 
least one year after delivery when main-tained and operated in 
accordance with the operation or instruction manual.
    (d) Any sampler or analyzer offered for sale as part of a reference 
or equivalent method must bear a label or sticker indicating that it 
has been designated as part of a reference or equivalent method in 
accordance with part 53 and showing its designated method 
identification number.
    (e) If such an analyzer has two or more selectable ranges, the 
label or sticker must be placed in close proximity to the range 
selector and indicate which range or ranges have been included in the 
reference or equivalent method designation.
    (f) An applicant who offers samplers or analyzers for sale as part 
of a reference or equivalent method is required to maintain a list of 
ultimate purchasers of such samplers or analyzers and to notify them 
within 30 days if a reference or equivalent method designation 
applicable to the method has been canceled or if adjustment of the 
sampler or analyzer is necessary under 40 CFR 53.11(b) to avoid a 
cancellation.
    (g) An applicant who modifies a sampler or analyzer previously 
designated as part of a reference or equivalent method is not permitted 
to sell the sampler or analyzer (as modified) as part of a reference or 
equivalent method (although it may be sold without such 
representation), nor to attach a label or sticker to the sampler or 
analyzer (as modified) under the provisions described above, until the 
applicant has received notice under 40 CFR 53.14(c) that the original 
designation or a new designation applies to the method as modified, or 
until the applicant has applied for and received notice under 40 CFR 
53.8(b) of a new reference or equivalent method determination for the 
sampler or analyzer as modified.
    (h) An applicant who offers PM2.5 samplers for sale as 
part of a reference or equivalent method is required to maintain the 
manufacturing facility in which the sampler is manufactured as an ISO 
9001-certified facility.
    (i) An applicant who offers PM2.5 samplers for sale as 
part of a reference or equivalent method is required to submit annually 
a properly completed Product Manufacturing Checklist, as specified in 
part 53.
    Aside from occasional breakdowns or malfunctions, consistent or 
repeated noncompliance with any of these conditions should be reported 
to: Director, Human Exposure and Atmospheric Sciences Division (MD-77), 
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 this method should be directed to 
the applicant.

Receipt of New Application

    EPA is also hereby announcing that it has received a new 
application for an equivalent method determination under 40 CFR part 
53. Publication of a notice of receipt of such applications is required 
by section 53.5.
    On January 12, 2000, EPA received an application for an equivalent 
method determination from Andersen Instruments, Incorporated, 500 
Technology Court, Smyrna, Georgia for its Series FH 62 C14 Suspended 
Particle Monitor for monitoring PM10 in the atmosphere. If, 
after appropriate technical study, the Administrator determines that 
this method should be designated as an equivalent method under 40 CFR 
part 53, notice thereof will be published in a subsequent issue of the 
Federal Register.
