EMF and Noise Studies
When utilities construct transmission facilities, they take actions and use techniques to mitigate noise during construction and operation. Tri-State and PSCo have taken steps to model the generation of audible noise and within their design plan to implement certain methods to reduce the noise during operation.
Additionally, the utilities have modeled electromagnetic fields that the proposed transmission lines would produce. A computer program is used to accurately predict the magnetic fields within the transmission corridors.

Electromagnetic fields (EMFs) are invisible lines of force associated with the production, transmission, and use of electric power such as those associated with high-voltage transmission lines, secondary power lines, and home wiring and lighting. Many studies of EMF have been conducted but none have identified a mechanism where EMF can cause disease. Visit the following Web sites to investigate the topic further:
