New Equivalent Method 

AGENCY: Environmental Protection 

Agency. 

ACTION: Notice of the designation of a 

new equivalent method for monitoring 

ambient air quality. 

SUMMARY: Notice is hereby given that 

the Environmental Protection Agency 

(EPA) has designated, in accordance 

with 40 CFR Part 53, a new equivalent 

method for measuring concentrations of 

sulfur dioxide (SO2) in the ambient air.

SUPPLEMENTARY INFORMATION: In 

accordance with regulations at 40 CFR 

Part 53, the EPA evaluates various 

methods for monitoring the 

concentrations of those ambient air 

pollutants for which EPA has 

established National Ambient Air 

Quality Standards (NAAQSs) as set 

forth in 40 CFR Part 50. Monitoring 

methods that are determined to meet 

specific requirements for adequacy are 

designated by the EPA as either 

reference methods or equivalent 

methods (as applicable), thereby 

permitting their use under 40 CFR Part 

58 by States and other agencies for 

determining attainment of the NAAQSs. 

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). 

As a designated reference or 

equivalent method, this method 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 and subject 

to any specifications and limitations 

(e.g., configuration or operational 

settings) specified in the applicable 

designation method description (see the 

identifications of the method 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 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. 

In general, a method designation 

applies to any sampler or analyzer 

which is identical to the sampler or 

analyzer described in the application for 

designation. In some cases, similar 

samplers or analyzers manufactured 

prior to the designation may be 

upgraded or converted (e.g., by minor 

modification or by substitution of the 

approved operation or instruction 

manual) so as to be identical to the 

designated method and thus achieve 

designated status. The manufacturer 

should be consulted to determine the 

feasibility of such upgrading or 

conversion. 

Part 53 requires that sellers of 

designated reference or equivalent 

method analyzers or samplers comply 

with certain conditions. These 

conditions are specified 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 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.

(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. 

(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 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. 

Designation of this new equivalent 

method is intended to assist the States 

in establishing and operating their air 

quality surveillance systems under 40 

CFR Part 58. Questions concerning the 

commercial availability or technical 

aspects of the method should be 

directed to the applicant.
