Ambient Air Monitoring Reference and Equivalent Methods:
Designation of a Reference Method and an Equivalent Method, and Receipt
of Two New Applications for Reference Method Determinations
AGENCY: Environmental Protection Agency.
ACTION: Notice of designations and receipt of applications.
-----------------------------------------------------------------------
SUMMARY: Notification is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with 40 CFR part 53, a new
reference method for measuring concen-trations of NO2 in
ambient air and a new equivalent method for measuring concentrations of
PM10 in ambient air. Notification is also given that EPA has
received two new applications for PM10 reference method
determinations under 40 CFR part 53.
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.

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. EPA hereby announces the designation of a new reference
method for measuring NO2 in ambient air and a new equivalent
method for measuring PM10 in ambient air. These designations
are made under the provisions of 40 CFR part 53, as amended on July 18,
1997 (62 FR 38764).
The new reference method for NO2 is an automated method
(analyzer) that utilizes the reference method measurement principle
based on the chemiluminescent reaction between nitric oxide and ozone
and the associated calibration procedure specified in Appendix F of 40
CFR part 50. The new equivalent method for PM10 is an
automated monitoring method that utilizes a measurement principle based
on sample collection by filtration and analysis by beta-ray
attenuation. The newly designated methods are identified as follows:
RFNA-0798-121, ``DKK Corporation Model GLN-114E Nitrogen Oxides
Ana-lyzer,'' operated within a temperature range of 20 to 30 degrees
C on any of the following measurement ranges: 0-0.005, 0-0.100, 0-
0.200, 0-0.500, and 0-1.000 ppm.
EQPM-0798-122, ``Met One Instruments Models BAM 1020, GBAM 1020,
BAM 1020-1, and GBAM 1020-1 PM10 Beta Attenuation Monitor,''
including the BX-802 sampling inlet, operated for 24-hour average
measurements, with a filter change frequency of one hour, with glass
fiber filter tape, and with or without any of the following options:
BX-823, tube extension; BX-825, heater kit; BX-826, 230 Vac heater
kit; BX-828, roof tripod; BX-902, exterior enclosure; BX-903,
exterior enclosure with temperature control; BX-961, mass flow
controller; and BX-967, internal calibration device.
An application for a reference method determination for the DKK
Model GLN-114E NO2 method was received by EPA on April 14,
1998, and a notice of the receipt of this application was published in
the Federal Register on June 2, 1998. The Model GLN-114E analyzer is
available from the applicant, DKK Corporation, 4-13-14, Kichijoji
Katamachi, Musashino-shi, Tokyo, 180, Japan.
An application for an equivalent method determination for the Met
One PM10 method was received by the EPA on September 12,
1997, and a notice of the receipt of this application was published in
the Federal Register on December 16, 1997. The method is available
commercially from the applicant, Met One Instruments, Inc., 1600
Washington Boulevard, Grants Pass, OR 97526.
Test analyzers representative of each of these methods have been
tested by the respective applicants 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 applicants, EPA has determined, in accordance with
part 53, that these methods should be designated as reference and
equivalent methods,
[[Page 41254]]
respectively. The information submitted by the applicants 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 implementing the Freedom of Information Act).
As a designated reference or equivalent method, each of these
methods 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, the specifications and limitations (e.g., sample period or
measurement range) specified in the applicable designation method
description (see identification of the methods 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-
94/038b). 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
designation application. In some cases, similar samplers or analyzers
manufactured prior to the designation may be upgraded (e.g., by minor
modification or by substitution of a new 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 maintained 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 show 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 he may choose to sell it without such
representation), nor to attach a label or sticker to the sampler or
analyzer (as modified) under the provisions described above, until he
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 he 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-registered 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, National Exposure Research Laboratory, Human Exposure and
Atmospheric Sciences Division (MD-77), U.S. Environmental Protection
Agency, Research Triangle Park, North Carolina 27711.
Designation of these reference and equivalent methods is intended
to assist the States in establishing and operating their air quality
surveillance systems under part 58. Questions concerning the commercial
availability or technical aspects of any of these methods should be
directed to the appropriate applicant.
Receipt of New Reference Method Applications
EPA is also hereby announcing that it has received two new
applications for reference method determinations under 40 CFR part 53.
Publication of a notice of receipt of such applications is required by
Sec. 53.5.
The new applications were received from BGI Incorporated, 58 Guinan
Street, Waltham, Massachusetts 02154, for reference method
determinations for that Company's Model PQ-100 PM10 Ambient Particulate
Sampler (application received on May 4, 1998) and for its Model PQ-200
Ambient Fine Particle Sampler (application received on June 1, 1998).
If, after appropriate technical study, the Administrator determines
that either or both of these methods should be designated as reference
methods, notice thereof will be published in a subsequent issue of the
Federal Register.
Dated: July 23, 1998
