Ambient Air Monitoring Reference and 

Equivalent Methods: Designation of 

One New Equivalent Method 

AGENCY: Environmental Protection 

Agency. 

ACTION: Notice of the designation of one 

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, one new 

equivalent method for measuring 

concentrations of lead (Pb) in total 

suspended particulate matter (TSP) in 

the ambient air.

and Atmospheric Sciences Division

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 compliance with the 

NAAQSs. 

The EPA hereby announces the 

designation of one new equivalent 

method for measuring Pb in TSP in the 

ambient air. This designation is made 

under the provisions of 40 CFR Part 53, 

as amended on November 12, 2008 (73 

FR 67057–67059). 

The new equivalent method for Pb is 

a manual method that uses the sampling 

procedure specified in the Reference 

Method for the Determination of 

Suspended Particulate Matter in the 

Atmosphere (High-Volume Method), 40 

CFR Part 50, Appendix B, with an 

alternative extraction and analytical 

procedure. The method is identified as 

follows: 

EQL–0510–191, ‘‘Determination of Lead 

Concentration in TSP by Inductively Coupled 

Plasma Mass Spectrometry (ICP–MS) with 

Heated Ultrasonic Nitric and Hydrochloric 

Acid Filter Extraction.’’ 

In this method, total suspended 

particulate matter (TSP) is collected on 

glass fiber filters according to 40 CFR 

Appendix B to part 50, EPA Reference 

Method for the Determination of 

Suspended Particulate Matter in the 

Atmosphere (High-Volume Method), 

extracted with a solution of nitric and 

hydrochloric acids, heated to 80 °C and 

sonicated for one hour, and brought to 

a final volume of 40 mL. The lead 

content of the sample extract is 

analyzed by Inductively Coupled 

Plasma-Mass Spectrometry (ICP–MS) 

based on EPA SW–846 Method 6020A. 

The application for an equivalent 

method determination for this method 

was submitted by the Office of Air 

Quality Planning and Standards, U.S. 

Environmental Protection Agency, 

Research Triangle Park, NC 27711 and 

was received by the Office of Research 

and Development on October 29, 2009. 

The analytical procedure of this 

method has been tested in accordance 

with the applicable test procedures 

specified in 40 CFR Part 53, as amended 

on November 12, 2008. After reviewing 

the results of those tests and other 

information submitted in the 

application, EPA has determined, in 

accordance with Part 53, that this 

method should be designated as an 

equivalent method for lead. The 

information 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, 

and will be available for inspection 

(with advance notice) 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 the requirements of 40 CFR Part 

58, Ambient Air Quality Surveillance. 

For such purposes, the method must be 

used in strict accordance with the 

complete operating procedure (SOP) 

associated with the method and subject 

to any specifications and limitations 

specified in the procedure. 

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, 

Ambient Air Quality Monitoring 

Program’’ EPA–454/B–08–003, 

December, 2008. 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. 

Consistent or repeated 

noncompliance with the method 

procedure/SOP 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 

technical aspects of the method should 

be directed to the applicant.

Acting Director, National Exposure Research 

Laboratory.

Weekly receipt of Environmental Impact 

Statements 

Filed 05/17/2010 Through 05/21/2010 

Pursuant to 40 CFR 1506.9. 

Notice: In accordance with Section 

309(a) of the Clean Air Act, EPA is 

required to make its comments on EISs 

issued by other Federal agencies public. 

Historically, EPA has met this mandate 

by publishing weekly notices of 

availability of EPA comments, which 

includes a brief summary of EPA’s 

comment letters, in the Federal 

Register. Since February 2008, EPA has 

been including its comment letters on 

EISs on its website at: http://www.epa.

gov/compliance/nepa/eisdata.html. 

Including the entire EIS comment letters 

on the website satisfies the Section 

309(a) requirement to make EPA’s 

comments on EISs available to the 

public. Accordingly, on March 31, 2010, 

EPA discontinued the publication of the 

notice of availability of EPA comments 

in the Federal Register.
