For the environmental sustainability, the program has been advanced, which involves: 1) Investigate soil pollution in places with high pollution potential. 2) Groundwater monitoring wells maintenance and groundwater investigation in both dry and wet season. 3) To assist and supervise declaration and facilities improvement of gas stations. 4) Counseling on compliance with laws and regulations for above-ground storage tanks 5) To supervise control sites. 6) The advertisement and education of storage tank regulations. 7) Dealing with emergency cases, and administrative assistances. 　　The plan has been executed from January 1th 2021 to December 20th 2021, and the results of implementation are summarized as follows. 　　A total of two soil surveys of high-pollution potential sites were carried out. Among them, the ‘Cu’, ‘Cr’, ‘Pb’ and TPH in the open space in front of Dongyin Power Plant exceeded the soil pollution control standards, and the ‘As’ exceeded the soil pollution monitoring standards. 　　The task of groundwater monitoring wells inspection was implemented four times this year averagely and there were totally 44 maintenance works finished. The one groundwater monitoring well screens also were completed, and two purges of monitoring well were implemented according to the screen results.

In addition, groundwater monitoring was conducted on the Howo Reservoir, showing that the quality of groundwater is still affected by seawater. 　　With respect to the mission of to assist and supervise declaration and facilities improvement of gas stations, the three times of declaration checks, gas stations assistance were completed. 　　In terms of laws enforcements and education, the meetings about storage tank regulations were completed.
