Due to the environmental impact, continuous monitoring is carried out.
3. Inspection and investigation of gas stations
The results of monthly inspections and online declarations showed no abnormality; in the investigation of leak detection pipes, 17 stations were completed from April 19th to 23rd, and the inspection results of the Chidong and Tongliang gas stations were found to belong to Class A, soil and groundwater survey operations have been arranged. The Wangan Fishing Boat Gas Station completed the soil sampling operation on August 18, and there was no abnormality; the groundwater sampling operation was completed on September 24, and the test results showed no abnormality.
4. The new business regulation compliance operation of the underground storage tank system
The audit work has been carried out for the revision of regulations this year, and 38 sites and 2 sites outside the list have been implemented. Follow-up will continue to track the units that need to be improved.
5. Inspection, supervision and investigation of polluted sites
For the inspection of abnormal gas stations this year, the pollution investigation operation was carried out. The sampling operation of Chidong and Tongliang gas stations was carried out from August 19 to 20. No situation exceeding the pollution control standard was found, but the Chidong gas station showed some potential pollution. Potential characteristics, the factory has been suggested to do a good job in maintenance and management. Jianshan Power Plant is a formerly polluted site, and the survey results have not exceeded the control standards.
In response to the compliance work of the new business regulations of the underground storage tank system, the head of the Environmental Protection Agency and its executive team were invited to complete the regulation briefing on March 4; the campus publicity work was completed 10 times between October and November.
