Ambient Air Monitoring Reference and Equivalent Methods;
Designation of Two Reference Methods and Two Equivalent Methods
AGENCY: Environmental Protection Agency.
ACTION: Notice of designation.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that the Environmental Protection
Agency (EPA) has designated, in accordance with 40 CFR part 53, two new
reference methods for the measurement of PM2.5
concentrations in the ambient air and two new equivalent methods for
the measurement of sulfur dioxide and ozone (respectively) in the
ambient air.

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: EPA announces the designation of two new
reference methods for measuring mass concentrations of particulate
matter as PM2.5 in the ambient air and two new equivalent
methods, for monitoring concentrations of sulfur dioxide
(SO2) and ozone (O3), respectively, in the
ambient air. These designations are made under the provisions of 40 CFR
part 53, as amended on July 18, 1997 (62 FR 38764).
Each of the new reference methods is a manual monitoring method
based on a particular PM2.5 sampler, one being a single-
filter sampler and the other capable of automatically collecting
multiple (sequential) samples. The first equivalent method is an
automated method (analyzer) for SO2 that utilizes a
measurement principle based on ultraviolet fluorescence. The other
equivalent method is an automated method (analyzer) for O3
that utilizes a measurement principle based on absorption of
ultraviolet radiation at a wavelength of 254 nm. The new methods are
identified as follows:
RFPS-0598-119, ``Graseby Andersen Model RAAS2.5-100
PM2.5 Ambient Air Sampler,'' operated with software version
4B configured for ``Single 2.5'' operation, for 24-hour continuous
sample periods at a flow rate of 16.67 liters/minute, and in accordance
with the Model RAAS2.5-100 Operator's Manual and with the requirements
and sample collection filters specified in 40 CFR Part 50, Appendix L.
RFPS-0598-120, ``Graseby Andersen Model RAAS2.5-300
PM2.5 Sequential Ambient Air Sampler,'' operated with
software version 4B configured for ``Multi 2.5'' operation, for 24-hour
continuous sample periods at a flow rate of 16.67 liters/minute, and in
accordance with the Model RAAS2.5-300 Operator's Manual and with the
requirements and sample collection filters specified in 40 CFR Part 50,
Appendix L.

following ranges: 0-0.05 ppm or 0-0.1 ppm or 0-0.2 ppm or 0-0.5 ppm or
0-1.0 ppm, with any selectable time constant from 10 to 300 seconds.
EQOA-0992-087, ``Advanced Pollution Instrumentation, Inc. Model 400
or 400A 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, with the dynamic zero and span adjustment feature (some Model
400 units only) set to OFF, with a 5-micron TFE filter element
installed in the rear-panel filter assembly, and with or without any of
the following options: Zero/Span Valve option, Internal Zero/Span (IZS)
option, IZS ozone generator reference feedback option, standard serial
port or Multi-drop RS-232, digital status outputs, analog outputs: 100
mV, 1 V, 5 V, 10 V, 4-20 mA current loop, optional metal wool ozone
scrubber, optional external sample pump, optional 47 mm diameter
filter, optical bench heater, rack mount with slides.
An application for reference method determinations for the Graseby
Andersen PM2.5 methods was received by the EPA on January 8,
1998, and a notice of the receipt of this application was published in
the Federal Register on February 10, 1998. The methods are available
commercially from the applicant, Graseby Andersen, 500 Technology
Court, Smyrna, GA 30082.
An application for an equivalent method determination for the
Horiba Model APSA-360ACE SO2 method was received by EPA on
March 26, 1998 (publication of notice of receipt in the Federal
Register is currently pending). The Horiba Model APSA-360 was
previously designated as an equivalent method (62 FR 6968) and
continues to be designated, although it will be commercially superseded
by the Model APSA-360ACE. These analyzers are available from the
applicant, Horiba Instruments, Incorporated, 17671 Armstrong Avenue,
Irvine, CA 92714.
An application for an equivalent method determination for the
Advanced Pollution Instrumentation, Inc. (API) Model 400A O3
method was received by EPA on February 24, 1998 (publication of notice
of receipt in the Federal Register is currently pending). The API Model
400 was previously designated as an equivalent method (57 FR 44565) and
continues to be designated, although it will be commercially superseded
by the Model 400A. These analyzers are available from the applicant,
Advanced Pollution Instrumentation, Incorporated, 6565 Nancy Ridge
Drive, San Diego, CA 92121.
Test samplers or 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 or
equivalent methods, as appropriate. 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
operating temperature range) specified in the applicable designation
method description (see identification of the methods above), and (for
PM2.5 reference methods) the specifications and requirements
set forth in Appendix L to 40 CFR part 50. Use of the method should
also be in general accordance with the guidance and recommendations of
Quality Assurance Guidance Document 2.12 (for PM2.5
reference methods) or other applicable section 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 part 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
[[Page 31993]]
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
part 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.
In a notice in the April 16, 1998 issue of the Federal Register (63
FR 18911), the EPA announced that a method for monitoring
PM2.5 in the ambient air identified as ``RFPS-0498-116, BGI
Incorporated Model PQ200 PM2.5 Ambient Find Particle
Sampler'' was ``conditionally'' designated as a reference method under
Sec. 53.51(b)(2) pending ISO 9001 certification of the BGI
manufacturing facility. That certification is now complete, and the
designation of the PM2.5 reference method based on the BGI
Model PQ200 sampler (BGI, Incorporated, 58 Guinan Street, Waltham, MA
02154) is no longer conditional.
