Office of Research and Development; 

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. 

FOR FURTHER INFORMATION CONTACT:

and Atmospheric Sciences Division 

(MD–D205–03), National Exposure 

Research Laboratory, U.S. EPA,

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 lead (Pb) in total 

suspended particulate matter (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 method is identified as follows: 

EQL–0310–189, ‘‘Procedure for 

Determination of Lead in Ambient Air 

TSP by Hot Plate Acid Extraction and 

ICP–MS Analysis.’’ 

In this method, total suspended 

particulate matter (TSP) is collected 

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 on a hot plate with 

3M HNO3 according to 40 CFR 

Appendix G to part 50, EPA Reference 

Method for the Determination of Lead in 

Suspended Particulate Matter Collected 

from Ambient Air, and 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 Inter-Mountain 

Laboratories, Incorporated, 1673 Terra 

Avenue, Sheridan, WY 82801 and was 

received by the Office of Research and 

Development on December 16, 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 provided by the applicant 

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 procedures (SOPs) 

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 (available at http:// 

www.epa.gov/ttn/amtic/qabook.html). 

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. 

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.

Advisory Committee (FRRCC) 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of Charter Renewal 

The Charter for the Environmental 

Protection Agency’s Farm, Ranch, and 

Rural Communities Advisory 

Committee (FRRCC) will be renewed for 

an additional two-year period, as a 

necessary committee which is in the 

public interest, in accordance with the 

provisions of the Federal Advisory 

Committee Act (FACA), 5 U.S.C. App.2. 

The purpose of the FRRCC is to provide 

advice to the Administrator of EPA on 

environmental issues and policies that 

are of importance to agriculture and 

rural communities. It is determined that 

the FRRCC is in the public interest in 

connection with the performance of 

duties imposed on the Agency by law.
