Proposed Data Collections Submitted for Public Comment and 

    In compliance with the requirement of Section 3506(c)(2)(A) of the 
Paperwork Reduction Act of 1995 for opportunity for public comment on 
proposed data collection projects, the Centers for Disease Control and 
Prevention (CDC) will publish periodic summaries of proposed projects. 
To request more information on the proposed projects or to obtain a 
copy of the data collection plans and instruments, call the CDC Reports 
Clearance Officer on (404) 498-1210 or send an e-mail to [email protected].
    Comments are invited on: (a) Whether the proposed collection of 
information is necessary for the proper performance of the functions of 
the agency, including whether the information shall have practical 
utility; (b) the accuracy of the agency's estimate of the burden of the

proposed collection of information; (c) ways to enhance the quality, 
utility, and clarity of the information to be collected; and (d) ways 
to minimize the burden of the collection of information on respondents, 
including through the use of automated collection techniques or other 
forms of information technology. Send comments to Sandi Gambescia, CDC 
Assistant Reports Clearance Officer, 1600 Clifton Road, MS-E11,

Proposed Project

    Assessment of Occupational Electric and Magnetic Field (EMF) 
Exposures--Validation of Interview Procedures used in a Brain Tumor 
Study against Measurements of Biologically-based Exposure Metrics--
New--National Institute for Occupational Safety and Health (NIOSH), 
Centers for Disease Control and Prevention (CDC).
    This study to assess occupational exposures to electric and 
magnetic fields (EMF) has the following objectives: (1) Validate an 
interview-based EMF exposure assessment algorithm against measurements 
of the time-weighted average (TWA) magnetic field magnitude used in 
previous epidemiologic studies, (2) calibrate the parameters in the 
algorithm in order to improve the exposure estimates, and (3) determine 
the correlation between the EMF exposures from the algorithm and 
biologically-based metrics measured by new instrumentation. These 
biologically-based metrics consist of either characteristics of the 
magnetic field that have produced biological effects in laboratory 
studies or currents in the body resulting from contact with charged 
surfaces. For the higher correlations with the TWA magnetic field 
magnitude, these data will be used to determine whether the exposure 
algorithm can be modified to accurately assess exposures to the 
biologically-based metrics.
    This is a one-time study of workers of an electric utility in 
Canada and a federal research laboratory in the U.S. There will be no 
cost to respondents.
