In this project, the functions of audit, control, tracking and analyzing were strengthened which was based on law revision. Meanwhile, the countrywide training courses and the consulting service which contain 18 courses, materials, videos and highlight videos were provided to enhance the efficiency of the users who deals with the related affairs. Besides, because the laws of pollutant permit are integrated, some systems are influenced. Therefore, this project collected the current situations of usage, function, and mechanism from 8 related systems and held a consulting meeting with related departments and companies.
