The EPA hereby announces the designation of a new equivalent method for measuring concentrations of sulfur dioxide (SO2) in the ambient air. This designation is made under the provisions of 40 CFR Part 53, as amended on December 18, 2006 (71 FR 61271).
The new equivalent method is an automated method (analyzer) that utilizes a measurement principle based on ultraviolet fluorescence. The newly designated equivalent SO2 method is identified as follows:
EQSA-0507-166, “SIR, S.A. Model S-5001 U.V. Fluorescence SO2 Analyzer, ” operated with a full-scale measurement range of 0-0.5 ppm, with an integration time setting of 1 minute, and with or without an optional PCMCIA Card or the optional Internal Span permeation oven.
An application for an equivalent method determination for the candidate method based on this SO2 analyzer was received by the EPA on October 4, 2006. The sampler is commercially available from the applicant, SIR USA, 826 West Braddock Road, Alexandria, VA 22302-3605 or from SIR Spain, Avenida de la Industria, 3; 28760 Tres Cantos (Madrid), Spain.
A test analyzer representative of this method has been tested in accordance with the applicable test procedures specified in 40 CFR Part 53 (as amended on December 18, 2006). After reviewing the results of those tests and other information submitted by the applicant in the application, EPA has determined, in accordance with Part 53, that this method should be designated as an equivalent method. The information submitted by the applicant in the application will be kept on file, either at EPA's National Exposure Research Laboratory, Research Triangle Park North Carolina 27711 or in an approved archive storage facility. That information will be made available for inspection (upon request and with advance notice) to the extent consistent with 40 CFR Part 2 (EPA's regulations implementing the Freedom of Information Act).
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 I,” EPA/600/R-94/038a and “Quality Assurance Handbook for Air Pollution Measurement Systems, Volume II, Part 1,” EPA-454/R-98-004 (available at http://www.epa.gov/​ttn/​amtic/​qabook.html). Vendor modifications of a designate 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 (Modifications of Methods by Users) of Appendix C to 40 CFR Part 58.
(c) The sampler or analyzer must function within the limits of the applicable performance specifications given in 40 CFR 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 as been designated as part of a reference or equivalent method in accordance with Part 53 and showing its designated method identification number.Start Printed Page 26628
(e) If such an analyzer has two or ore selectable ranges, the label or sticker must be placed in close proximity to the range selector and indicator which range or ranges have been included in the reference or equivalent method designation.
(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 designation label or sticker to the sampler or analyzer (as modified) under the provisions described above, until the applicant 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 the applicant has applied for an received notice under 40 CFR 53.8(b) of a new reference or equivalent method determination for the sampler or analyzer as modified.
Aside from occasional breakdown or malfunctions, consistent or repeated noncompliance with any of these conditions should be reported to: Director, Human Exposure and Atmospheric Sciences Division (MD-E205-01), National Exposure Research Laboratory, U.S. Environmental Protection Agency, Research Triangle Park, North Carolina 27711.
