Environment considerations with the second phase


Monitoring of the influence onto the environment



next

An environment monitoring plan has been mapped out in cooperation with the governor of Osaka and the mayors of the 9 cities and 4 towns of the area in order to grasp the influence of the work of phase 2 onto the environment, to prevent deterioration of the environment by taking suitable measures as required, and to check for problems in regard to environment protection by comparison with environment protection targets.
This plan is used as the basis for environment monitoring.
