Ambient Air Monitoring Reference and Equivalent Methods;
Reference Method Designation
Notice is hereby given that EPA, in accordance with 40 CFR part 53,
has designated another reference method for the determination of
ambient concentrations of particulate matter measured as PM10. The
new reference method is a gravimetric method which utilizes a specially
designed PM10 sampler for particle collection. The designated
method is identified as follows:
RFPS-0694-098, ``Rupprecht & Patashnick PartisolTM Model
2000 Air Sampler'', consisting of a Hub Unit and 0, 1, 2, or 3
Satellite Units, with each sampling station used for PM10
measurements equipped with a Rupprecht & Patashnick PM10 Inlet
and operated for continuous 24-hour periods using the Basic, Manual,
Time, Analog Input, or Serial Input programming modes, and with or
without any of the following options:
Stand for Hub or Satellite
57-002320
Advanced EPROM
59-002542
Large Pump (\1/4\ hp), 120 VAC
10-001403
Hardware for Indoor Installation consisting of:
Temperature Sensor (Extended
Length)
51-002638-xxxx
Roof Flange (1\1/4\'')
55-001289
Support Tripod for Inlet
57-000604
Sample Tube Extension
(1 m)
57-002526-0001
Sample Tube Extension
(2 m)
57-002526-0002
Hardware for Outdoor Installation in Extreme Cold Environments:
Insulating Jacket for Hub Unit
10-002645
This method is available from Rupprecht & Patashnick Co., Inc.
(R&P), 25 Corporate Circle, Albany, New York 12203. A notice of receipt
of application for this method appeared in the Federal Register, Volume
59, March 30, 1994, page 14853.
The hub unit of the PartisolTM Model 2000 Air Sampler contains
a filter holder assembly, the flow control system, the valves to direct
the sample flow through the hub or appropriate satellite unit, the
sample pump, a microprocessor, keypad, information display, and
associated electronics. Each satellite unit contains only a filter
holder assembly and is connected to the hub unit through a single flow
line. Each sampling station (hub or satellite) used for PM10
measurements must be equipped with an R&P PM10 inlet (other
sampling stations may have other types of inlets). Only one sampling
station may operate at a time.
The Model 2000 uses 47mm diameter filters mounted in cassettes.
Filter media meeting the minimum requirements specified in appendix J
to 40 CFR part 50 (Reference Method for the Determination of
Particulate Matter as PM10 in the Atmosphere) are available from
R&P, or may be obtained from other sources, depending on individual
user needs. A 5-place analytical balance is required for weighing
filters before and after sampling.
Test samplers representative of this method have been tested by the
applicant, in accordance with the test procedures specified in 40 CFR
part 53. After reviewing the results of these tests and other
information submitted by the applicant, EPA has determined, in
accordance with part 53, that this method should be designated as a
reference method. The information submitted by the applicant will be
kept on file at EPA's Atmospheric Research and Exposure Assessment
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 method, this method is acceptable for use
by States and other air monitoring agencies under requirements of 40
CFR part 58, Ambient Air Quality Surveillance. For such purposes, the
method must be used in accordance with the guidance in appendix J to 40
CFR part 50 and the specific procedures contained in the operation or
instruction manual associated with the method. Use of the method is
also subject to any limitations specified in the applicable designation
(see description of the method above). Vendor modifications of a
designated method used for purposes of part 58 are permitted only with
prior approval of 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, this designation applies to any sampler which is
identical to the sampler described in the designation. Similar samplers
manufactured and sold 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 designation status at a modest cost. The manufacturer
should be consulted to determine the feasibility of such upgrading.
Part 53 requires that sellers of designated methods comply with
certain conditions. These conditions are given in 40 CFR 53.9 and are
summarized below for PM10 methods:
(1) A copy of the approved operation or instruction manual must
accompany the PM10 sampler when it is delivered to the ultimate
purchaser.
(2) The PM10 sampler must not generate any unreasonable hazard
to operators or to the environment.
(3) The PM10 sampler must function within the limits of the
performance specifications given in table D-1 of part 53 for at least
one year after delivery when maintained and operated in accordance with
the operation manual.
(4) Any PM10 sampler offered for sale as a reference or
equivalent method must bear a label or sticker indicating that it has
been designated as a reference or equivalent method in accordance with
part 53.
(5) An applicant who offers PM10 samplers for sale as
reference or equivalent methods is required to maintain a list of
ultimate purchasers of such samplers and to notify them within 30 days
if a reference or equivalent method designation applicable to the
sampler has been canceled or if adjustment of the samplers is necessary
under 40 CFR 53.11(b) to avoid a cancellation.
(6) An applicant who modifies PM10 sampler previously
designated as a reference or equivalent method is not permitted to sell
the sampler (as modified) as 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 (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 as modified.
Aside from occasional breakdowns or malfunctions, consistent or
repeated noncompliance with any of these conditions should be reported
to: Director, Atmospheric Research and Exposure Assessment Laboratory,
Department E (MD-77), U.S. Environmental Protection Agency, Research
Triangle Park, North Carolina 27711.
Designation of this reference method will provide assistance to the
States in establishing and operating their air quality surveillance
systems under part 58. Technical questions concerning the method should
be directed to the manufacturer. Additional information concerning this
action may be obtained from Frank F. McElroy, Methods Research and
Development Division (MD-77), Atmospheric Research and Exposure
Assessment Laboratory, U.S. Environmental Protection Agency, Research
Triangle Park, North Carolina 27711, (919) 541-2622.

Assistant Administrator for Research and Development.
