Power Lines and Electro Magnetic Fields (EMFs)
New power line developments must comply with the 1998 ICNIRP Guidelines for exposure to Electro Magnetic Fields and should have optimum phasing as a precautionary measure. Proposals are assessed for impact on amenity and should avoid areas of landscape sensitivity including AONBs.
In relation to power lines current government policy is that exposures to power-line Electro Magnet Fields (EMFs) should comply with the 1998 International Commission on Non-Ionizing Radiation Protection (ICNIRP) Guidelines. Power Lines: Control of Microshocks and other indirect effects of public exposure to electric fields A voluntary Code of Practice (DECC, July 2013) has been agreed by the Department of Energy and Climate Change, the Department of Health, the Energy Networks Association, the Welsh Government, the Scottish Government, and the Northern Ireland Executive. It sets out what is regarded as compliance with those aspects of the EMF exposure guidelines that relate to indirect effects as far as the electricity system is concerned. Further government policies relating to EMFs from overhead power lines, advise that as a precautionary measure they should, where reasonable, have optimum phasing. This is the subject of a companion Code of Practice "Optimum phasing of high voltage double-circuit power lines". This Code of Practice applies in England, Wales, Scotland, and Northern Ireland. Any proposal for the development of new power lines should comply with the 1998 International Commission on Non-Ionizing Radiation Protection (ICNIRP). Furthermore, such proposals will be considered having regard to potential impact on amenity and should avoid areas of landscape sensitivity, including areas of outstanding natural beauty (AONBs).
