The environmental measure of transmission line construction

In order to construct a transmission line in a narrow country such as Japan, various environmental measures are implemented under restrictions of a flat-ground area and a mountainous region and the rise of environmental consciousness. In Japan, there is no law focused on environmental measures in transmission line construction. However, in some prefectures or local authorities, original environmental-impact-assessment regulations and instruction outlines are enacted, and cases where a transmission line is an object of environmental-impact assessment are increasing little by little.
