ENVIRONMENTAL PROTECTION AGENCY
[FRL-5876-2]
Ambient Air Monitoring Reference and Equivalent Methods DKK
Corporation; Designation of Equivalent Method
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of designation.
-----------------------------------------------------------------------
SUMMARY: Notice is hereby given that EPA, in accordance with 40 CFR
part 53, has designated another equivalent method for the measurement
of ambient concentrations of sulfur dioxide.
FOR FURTHER INFORMATION CONTACT: Berne I. Bennett, Human Exposure and
Atmospheric Sciences Division (MD-77B), National Exposure Research
Laboratory, U.S. Environmental Protection Agency, Research Triangle
Park, North Carolina 27711, (919) 541-2366.
SUPPLEMENTARY INFORMATION: Notice is given that designation of
equivalency has been granted to DKK Corporation, Kichijoji-Kitamachi-
shi, Tokyo, 180, Japan, for model GFS-32 Ambient Air SO2
Ultraviolet Fluorescent Analyzer. The newly designated method is
identified as follows:
EQSA-0701-115, DKK Corporation model GFS-32 Ambient SO2
ultraviolet fluorescent analyzer, operated within the 0.000 to 0.500
ppm range in the temperature range of 20 deg.C to 30 deg.C.
A representative analyzer has been tested for the applicant by the
Zedek Corporation, Durham, NC, in accordance with the test procedures
specified in 40 CFR part 53. 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 implementing the Freedom of Information Act).
As a designated equivalent 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 strict accordance with the operation manual
associated with the method and 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
(Modification of Methods by Users). In general, a designation applies
to any analyzer which is identical to the analyzer described in the
designation.
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:
(1) A copy of the approved operation or instruction manual must
accompany the analyzer when it is delivered to the user.
(2) The analyzer must not cause any unreasonable hazard to
operators or to the environment.
(3) The analyzer must function within the limits of the performance
specifications given in Table B-1 of part 53 for at least one year
after delivery when maintained and operated in accordance with the
operation manual.
(4) Any analyzer 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) If 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.
(6) An applicant who offers analyzers for sale as reference or
equivalent methods is required to maintain a list of ultimate
purchasers of such analyzers and to notify them within 30 days if a
designation has been cancelled, or if adjustment of the analyzer is
necessary under 40 CFR part 53.11(b) to avoid cancellation.
(7) An applicant who modifies an analyzer previously designated as
a reference or equivalent method is not permitted to sell the analyzer
(as modified) as a reference or equivalent method (although it may be
sold without such representation), nor to attach a label or sticker to
the analyzer (as modified) under the provisions described above, until
notice has been received under 40 CFR part 53.14(c) that the original
designation or a new designation applies to the method as modified or
until notice under 40 CFR 53.8(b) has been received of a new reference
or equivalent method determination for the analyzer as modified.
