Proposed Data Collections Submitted for Public Comment and 
Recommendations

    The Centers for Disease Control and Prevention (CDC) publishes a 
list of information collection requests under review by the Office of 
Management and Budget (OMB) in compliance with the Paperwork Reduction 
Act (44 U.S.C. Chapter 35). To request a copy of these requests, call 
the CDC Reports Clearance Officer at (404) 371-5976 or send an e-mail 
to [email protected]. Send written comments to CDC Desk Officer, Office of 
Management and Budget, Washington, DC via fax to (202) 395-6974. 
Written comments should be received within 30 days of this notice.

Proposed Project

    Assessment of Occupational Exposures to Electric and Magnetic 
Fields (EMF)--New--National Institute for Occupational Safety and 
Health (NIOSH), Centers for Disease Control and Prevention (CDC).
    This proposal is to conduct a validation study on an interview-
based procedure for assessing occupational exposures to electric and 
magnetic fields (EMF) from AC electricity. Participants in the study 
will be asked to wear specially designed instruments to measure a range 
of EMF that employees encounter as part of their daily work practices. 
These devices have been field-tested and meet all safety requirements. 
This study will capture not only the magnetic field magnitude but also 
its frequencies, induced currents and contact currents. This study will 
provide important new information that will shed light on EMF and 
health effects on workers.
    This study 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 except for their time.
